Diet Cola Chicken Recipe
Introduction
Diet cola chicken is a flavorful and surprisingly simple dish that combines tender chicken thighs with a tangy, slightly sweet sauce made from diet cola and pantry staples. It’s a great weeknight meal that’s both comforting and easy to prepare.

Ingredients
- 1 tsp olive oil
- 640g boneless and skinless chicken thighs
- 1 onion, finely chopped
- 300ml chicken stock
- 2 garlic cloves, finely chopped
- 1 red pepper, deseeded and cut into chunks
- 1 yellow pepper, deseeded and cut into chunks
- 1 tsp dried oregano
- 1 tsp light brown soft sugar
- ½ tsp mustard powder
- 1 tbsp Worcestershire sauce
- 3 tbsp tomato purée
- 330ml diet cola
- 2 tbsp reduced-salt-and-sugar ketchup
- 2 spring onions, trimmed and finely sliced
Instructions
- Step 1: Heat the olive oil in a large non-stick saucepan over high heat. Season the chicken thighs then brown them all over for 4-5 minutes. Remove the chicken with tongs and set aside on a plate.
- Step 2: Reduce the heat and add the chopped onion to the pan. Cook for 8-10 minutes until softened, adding a splash of chicken stock if needed to prevent sticking or burning. Stir in the garlic and cook for 1 minute until fragrant, then add the yellow pepper pieces.
- Step 3: Stir in the dried oregano, brown sugar, mustard powder, Worcestershire sauce, tomato purée, diet cola, remaining chicken stock, and ketchup. Bring the mixture to a boil.
- Step 4: Return the browned chicken thighs to the pan. Reduce the heat to a simmer, cover, and cook for 10 minutes until the chicken is cooked through.
- Step 5: Increase the heat and let the sauce bubble for another 10 minutes to reduce and thicken slightly.
- Step 6: Serve the chicken sprinkled with finely sliced spring onions, accompanied by rice or pasta to soak up the delicious sauce.
Tips & Variations
- For extra color and flavor, add the red pepper along with the yellow pepper in Step 2.
- Use Greek yogurt or sour cream as a creamy topping when serving to add richness without much extra effort.
- If you prefer a spicier sauce, add a pinch of chili flakes along with the garlic in Step 2.
- Chicken breasts can be used instead of thighs, but be mindful they may cook faster and dry out if overcooked.
Storage
Store any leftover chicken and sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently in a saucepan over low heat or in the microwave until heated through. The sauce may thicken upon standing; add a splash of water or stock when reheating to loosen it if needed.

- Sauté Onions and Garlic: Lower the heat to medium and add the finely chopped onion to the pan. Cook for 8-10 minutes until softened, adding a splash of chicken stock as needed to prevent the onion from burning. Stir in the chopped garlic and cook for an additional 1 minute until fragrant.

- Serve: Sprinkle the sliced spring onions over the dish and serve hot with rice or pasta of your choice.
