Seven chicken breasts, one bottle of Coca-Cola, a last-minute BBQ marinade rescue and almost ten hours in the slow cooker. What could possibly go wrong? (Famous last words, right?)

🥤 Coca-Cola… In My Dinner?!

There are some ingredients you expect to see when you’re making dinner.

Chicken? Absolutely. Barbecue sauce? Lovely. A bottle of Coca-Cola?

Honestly, I usually expect to drink my Coca-Cola with dinner, not pour it straight into the pot. Yet here we are, living dangerously.

Today’s Kitchen Notebook experiment: Slow Cooker Coca-Cola Chicken. This is one of those recipes I saved ages ago and only just got round to trying—classic me. And because I clearly like to keep life spicy, I found myself in the kitchen at 6 am, cooking chicken before heading off to spend the rest of my day cooking for other people’s little ones. Who needs sleep anyway?

The plan sounded simple enough: oven-cook the frozen chicken breasts, pop them in the slow cooker with the Coca-Cola BBQ sauce, and let dinner magically sort itself out. Well, that was the theory.

Spoiler: a minor cornflour emergency happened before we made it to the finish line.


📖 The Original Recipe

Today’s recipe comes from Spaceships and Laser Beams, with the current online article credited to Stephanie Keeping.

The recipe combines chicken breasts with Coca-Cola, barbecue sauce, and three simple seasonings, then cooks everything in the slow cooker. It also features an unusual two-stage sauce method: drain the initial cooking liquid partway through, then add the remaining cola and BBQ sauce for the final cooking period.

A Little Note About My Saved Recipe

I originally saved this recipe as a PDF several years ago. After finally tracking down the website again, I noticed that some of the online instructions now differ from my saved copy. My older version says to add most of the barbecue sauce and Coca-Cola at the start, reserving the rest for later. The current online version gives more specific quantities for each stage.

For this Kitchen Notebook experiment, I used my saved measurements as the starting point rather than automatically replacing them with the newer website instructions. As you’re about to discover, my actual cooking method ended up being quite different anyway!



🛒 What I Used

The original recipe needed only six ingredients, but of course my version took a few detours—a bottle rescue mission and a last-minute call for my trusty cornflour.


Original Ingredients vs My Kitchen

Original IngredientOriginal AmountWhat I Actually Used

A little seasoning clarification: I followed the original measurements exactly. The only substitution was onion granules instead of onion flakes, because that’s what I already had in the cupboard.

A Few Changes Before We Even Started

The recipe said six chicken breasts. I used seven, because five were left from my Alice’s Basket chicken bag and I couldn’t leave two lonely ones in the new packet. That’s just how my brain works.

Frozen chicken breasts can lose a noticeable amount of weight and liquid when you cook them in the oven, so I decided to use an extra breast.

And before anyone asks if I weighed each of those seven chicken breasts before cooking—absolutely not.

It was 6 am, the oven was already giving me attitude, and honestly, just remembering to take a photo of the ingredients felt like a win. So yes, I know exactly which chicken I used, but I had no way of faffing about with scales at that hour. I’ll explain more when we get to the Budget Breakdown.


The BBQ Bottle Rescue

Then came the barbecue sauce situation. The bottle only gave me approximately 200ml in the measuring jug.

Rather than let that precious sauce go to waste, I added a splash of water to the bottle, gave it a good shake (as you do), and poured in every last drop. That brought the BBQ mixture up to 380ml.

Waste not, want not—especially with barbecue sauce.

I also went with 380ml of Coca-Cola instead of the original 340ml. Maybe all that extra liquid would keep the chicken juicy through its marathon day in the slow cooker? That was the hope, anyway.

That was the theory, anyway.


💷 The Budget Breakdown

Time for our regular Kitchen Notebook budgeting investigation!

Two figures are worth distinguishing here: the price of buying all the products and the cost of the actual amounts that went into this dinner.

Because I used seven chicken breasts from two different frozen bags and didn’t weigh them before cooking, I can’t give an exact total of consumed ingredients without inventing a chicken weight.

And let’s be honest, there was zero chance I was standing there with kitchen scales at 6 am. Same goes for the exact grams of wedges and sweetcorn—I just wasn’t that organised.

I can show the reference product prices, calculate the known quantities, and clearly mark the remaining estimates.


Reference Full-Pack Prices

Iceland Chicken Breast Fillets 1.2kg£5.00 per bag
ASDA Smoky Kansas Style BBQ Marinade 280g£1.55
Coca-Cola Original Taste 1.25L£2.24
COOK by ASDA Ground Black Pepper 25g£1.20
COOK by ASDA Onion Granules 50g£1.06
COOK by ASDA Garlic Salt 85g£1.00
BAKE by ASDA Cornflour 250g£1.03
Iceland Southern Fried Wedges 1kg£2.00
Iceland Supersweet Sweetcorn 860g£2.00
One of each listed pack£17.08

Because today’s seven chicken breasts came from two separate 1.2kg bags, buying the same combination from scratch would bring the basket to £22.08, including two chicken bags and all the listed ingredients and sides.

That is a shopping-basket figure, not the cost of food actually consumed. It leaves plenty of Coca-Cola, seasonings, cornflour and potentially frozen ingredients for other meals.

Prices are based on previously checked online reference prices for October 2026, not my original till receipt. Actual purchase prices and promotions may differ.


How Much Did the Chicken Recipe Actually Use?

Seven chicken breastsExact cost unavailable without their original frozen weight
BBQ marinade, assuming the full bottle was emptied and rinsed£1.55
Coca-Cola, 380ml£0.68
Black pepper, 1 tspApprox. £0.11
Onion granules, 2 tspApprox. £0.10
Garlic salt, ½ tspApprox. £0.04
Cornflour, 3 tbspApprox. £0.10
WaterNegligible
Estimated subtotal excluding chicken£2.58

The seasoning quantities match the exact spoon measurements I used from the original recipe. Their costs are estimates because I measured them by teaspoon rather than weighing them in grams. I also estimated the cornflour cost from its three-tablespoon quantity.

At the listed reference price, the frozen chicken costs approximately £4.17 per kilogram before cooking. However, because I used a mixture of breasts from an older bag and a new one without weighing them, I’ll leave their exact consumed cost unconfirmed rather than assign them an invented weight.


The Cost Per Serving

Original stated yield: 6 servings
My provisional generous yield: Approximately 4–5 portions when sliced
Exact cost per original serving: Unavailable without the original chicken weight
Exact cost per generous portion: Unavailable without the chicken weight and confirmed final yield


The Sides

The wedges and sweetcorn were part of my complete plated dinner, but weren’t ingredients in the original Coca-Cola Chicken recipe. I’ll keep their cost separate so the recipe itself doesn’t look more expensive just because I fancied wedges!


⏰ The Real-Life Timings

Now, remember that lovely original estimate of four hours and five minutes?

My version had other ideas. Because I was using frozen chicken breasts, I returned to the oven-first approach I’d used for Alice’s Basket.

And, once again, my oven decided to test my patience and take its sweet time warming up. Classic.


My Actual Cooking Day

StageActual Time
Started the morning preparationApproximately 6:00am
Cooking the frozen chicken in the ovenApproximately 1 hour
Chicken transferred to slow cooker7:50 AM
Cornflour slurry addedApproximately 5:20pm
Chicken removed and dinner served5:45 PM
Slow-cooker time9 hours 55 minutes
Approximate morning-to-dinner elapsed time11 hours 45 minutes

That’s almost TEN hours in the slow cooker alone. A substantial difference from the original recipe, but thankfully I didn’t have to stand in the kitchen for most of that time.


🍗 First Things First: Cooking the Chicken

As mentioned, I used seven frozen Iceland chicken breasts rather than the six the original recipe suggested.

I decided to fully oven-cook them first instead of putting frozen or partially cooked chicken into the slow cooker. This was my own adaptation, not a step taken from the original recipe.

And the oven? One whole hour. Again. Honestly, I’m starting to think it just likes winding me up.

There was also quite a bit of liquid in the roasting tray after cooking, which is particularly worth noting when comparing the raw frozen product with the finished chicken.

The frozen and cooked weights aren’t interchangeable for a precise budget calculation.

A quick food-safety note: this post documents my cooking-day experience, not a recommendation to partially cook frozen poultry or use a slow cooker to reheat cold cooked chicken. Always follow appliance and product instructions, confirm that chicken is thoroughly cooked and keep food safely hot.


🥤 Preparing the Coca-Cola BBQ Sauce

With the chicken cooked, it was time to prepare the sauce. And here’s where we took our first proper detour.

The original recipe calls for specific quantities of BBQ sauce and cola, with some of each reserved for later.

Me? I just chucked everything in at once and hoped for the best.

No careful measuring, no setting aside a secret stash of sauce for later, no grand halfway plan. I just whacked the lot in and let the kitchen gods decide our fate.

I put the chicken in the slow cooker at 7:50 am, then added the seasoned BBQ mixture and Coca-Cola.

Lid on, fingers crossed, and off I went to work.


🕕 The All-Day Slow-Cooker Experiment

The original instructions say to drain the accumulated cooking liquid partway through, then add the reserved cola and BBQ sauce.

I didn’t do that. Mainly because I was at work. Since I added everything at the beginning, I let the chicken cook in the full sauce mixture all day.

And, admittedly, the extra liquid was still very noticeable by the evening.

This is where the photographs really show the difference between the original recipe’s intended two-stage method and what happened in my kitchen.

My sauce hadn’t naturally reduced to a thick, glossy consistency. But fortunately, I had a solution.


🥄 Cornflour to the Rescue!

By approximately 5:20 pm, the sauce was still far too runny for what I wanted to serve.

Enter my old faithful friend: cornflour, always ready to save the day.

Honestly, cornflour is one of my best kitchen friends at work, and now it’s officially part of my home-cooking rescue squad too. I mixed three tablespoons with water, put it in the slow cooker, and let it work its magic.

And look at the result.

Honestly, this might be my favourite progress photo from the whole recipe. Look at that shine!

We went from chicken bobbing around in a very generous amount of liquid to something much closer to the glossy sauce I’d hoped for.

Would following the original draining instructions have saved me from using cornflour? Possibly.

But that’s the fun (and chaos) of testing recipes in a real kitchen. You never know what will work, what won’t, or which random cupboard ingredient will swoop in to save dinner at the last minute!


🍖 The Finished Coca-Cola Chicken

At about 5:45 pm, dinner was ready—starting with the chicken.

It was already pulling apart as I lifted it out of the slow cooker. When I started slicing the breasts for the plates, it was definitely tender.

So my big worry about the chicken turning out dry after all those hours? Not the issue at all. The real drama was all about the sauce.

Rather than shredding the entire batch, I sliced the chicken for serving. This also made it easier to judge the actual generous portions.


🍽️ Bringing Dinner Together

For the full dinner experience, I served the Coca-Cola Chicken with Southern Fried Wedges and sweetcorn. Simple, sweet, smoky, and exactly the kind of meal that makes you want seconds.

My Dinner Menu

Main: Slow Cooker Coca-Cola Chicken

Sides: Iceland Southern Fried Wedges (air-fried) and Iceland Supersweet Sweetcorn.

The Products I Used

Potato wedges – Iceland Southern Fried Wedges 1kg

Sweetcorn – Iceland Supersweet Sweetcorn 860g


😋 The First Taste

So, after nearly ten hours in the slow cooker, was the Coca-Cola chicken worth the wait?

Well… it was good! Not life-changing, but definitely good.

The chicken itself was lovely and tender. It sliced easily, and the thickened sauce coated the pieces nicely. I could taste a definite sweetness from the Coca-Cola, which paired well with the barbecue flavour.

However, the Smoky Kansas Style BBQ Marinade also brought quite a spicy kick. And while I certainly don’t mind a bit of heat, it was noticeable enough to influence how the boys felt about dinner.

The combo worked, and I enjoyed eating it. Was it absolutely mind-blowing? Not really, but that’s okay.

Sometimes a recipe is just perfectly decent—not every dinner needs to be the best thing you’ve ever tasted. Not every Kitchen Notebook experiment gets a standing ovation, and that’s half the fun.


👦 The Boys’ Verdict

Now for our household food critics.

Big Boy

He tried the chicken, but unfortunately found it too spicy.

So yes, the sauce was sweet from the Coca-Cola, but the heat from that BBQ marinade was enough to put him right off. Mental note for next time if I want everyone at the table happy.

My Spud

His verdict? “Good.”

And he ate ALL his chicken! The wedges, however, were left behind.

So tonight’s win was all about the chicken, not the whole dinner. But honestly, with how particular Spud can be, I’m calling that a solid victory.

One boy thought the sauce was too hot; the other polished off his chicken. Family food reviews are never dull around here!


👩‍🍳 What I’d Change Next Time

This recipe has definitely left me with a few things to ponder for next time.

1. Consider a Milder BBQ Sauce

I liked the sweet-and-spicy combo, but Big Boy didn’t like the heat. A milder sauce might make this more of a crowd-pleaser without losing that Coca-Cola twist.


2. Revisit the Original Draining Stage

I chucked everything in at once, skipped the draining step, and needed cornflour to save the sauce. It worked, but I’m curious how it would turn out if I followed the original two-stage method next time.


3. Keep the Cornflour Handy

Three tablespoons of cornflour mixed with water did the trick right at the end. I wouldn’t add it automatically, but it’s definitely earned a spot in my notes for this version.


4. Remember the Generous Portions

Seven chicken breasts gave me way more wiggle room than six. Slicing the chicken instead of serving whole breasts made portioning so much easier—and less stressful.


❄️ What About the Leftovers?

The original recipe says six servings, but portion sizes in my kitchen always have a mind of their own.

With seven breasts and the way they cooked up, I’d say we ended up with about four to five generous portions.

If I served the breasts whole, I could portion them as one breast per serving.

My Actual Yield

Original recipe yield: 6 servings
Chicken breasts used: 7
Estimated generous yield when sliced: 4–5 portions


🔁 Would I Make Coca-Cola Chicken Again?

I wouldn’t rule it out—never say never in this kitchen!

The chicken was tender, the finished sauce was nicely thick after its cornflour rescue, and the Coca-Cola brought a sweetness that I could actually taste.

But I don’t think I’d call this an instant family favourite, especially with Big Boy’s spice radar on high alert.

The main change I’d consider is the choice of barbecue sauce. A milder one might make this much easier to serve to everyone without losing the sweet Coca-Cola flavour.

Although the original recipe’s sauce-draining method differs from mine, I’m pleased my improvised version still gave us a good dinner.

Not mind-blowing, not a disaster—just a perfectly decent midweek meal with a pretty entertaining kitchen story to go with it.


⭐ Final Rating & Thoughts

⭐⭐⭐☆☆ 3/5

Taste: ⭐⭐⭐☆☆ 3/5
Ease: ⭐⭐⭐☆☆ 3/5
Family Approval: ⭐⭐⭐☆☆ 3/5
Would I Make It Again?: Possibly, with a milder BBQ sauce and a few adjustments.

Three stars feels about right for this little experiment. The chicken was beautifully tender, the Coca-Cola sweetness came through, and trusty cornflour finally gave me the thick sauce I’d been dreaming of.

But was it mind-blowing? Not really.

Taste gets three stars because although I enjoyed the combination, I wasn’t completely won over by the finished flavour. The BBQ marinade added a spicy kick, and I think a milder sauce might have let the Coca-Cola’s sweetness shine through a little more.

Ease also gets three stars. The slow cooker did most of the work during the day, but the hour-long oven prep, nearly ten-hour cook time, and last-minute sauce rescue meant this wasn’t quite the effortless dinner the original recipe promised.

And family approval? Let’s call it mixed! Big Boy thought it was too spicy, but Spud ate every last bit of his chicken—which I’m absolutely counting as a win.

What I did enjoy was discovering that cooking with Coca-Cola isn’t nearly as weird as it sounds. It really did add sweetness to the sauce, and the chicken was lovely and tender after its marathon in the slow cooker.

Would I tinker with the recipe again? Quite possibly. I’d try a different barbecue sauce, maybe actually follow the draining step, and see if a few tweaks give us a more balanced result.

But that’s exactly why I love keeping this little Kitchen Notebook. Reading a recipe is one thing—actually making it, with whatever ingredients you’ve got, an oven with a mind of its own, and a busy day to juggle? That’s where the real stories happen.

Not every recipe needs to become a new family favourite. Sometimes a solid three-star dinner, a few lessons learned, and a bit of kitchen improvisation are more than enough.

And sometimes, all it takes is three tablespoons of cornflour to save the day (and dinner).
