- Olive oil – 1 tablespoon
- Onion – 1 large, sliced
- Red peppers – 2, deseeded and sliced
- Garlic cloves – 2, crushed
- Plain flour – 1 tablespoon
- Tomato purée – 1 tablespoon
- Chopped tomatoes – 1 × 400 g tin
- Chicken stock – 300 ml

Step-by-Step Cooking Guide
Cooking this Mary Berry Casserole is straightforward and enjoyable. Here’s a detailed step-by-step guide to help you master the dish.
1. Browning the Sausages
Start by heating olive oil in a large casserole pan. Add the sausages and cook until they are nicely browned all over. This step is crucial because browning enhances the flavor and ensures that your sausages remain juicy. Once browned, remove the sausages and set them aside.
2. Cooking the Vegetables
In the same pan, add sliced onions and red peppers. Cook them gently over medium heat until softened. This slow cooking brings out their natural sweetness and creates a rich base for the sauce. Adding garlic at this stage will give the dish a lovely aromatic depth. Cook the crushed garlic briefly until fragrant.
3. Building the Sauce
Sprinkle plain flour over the vegetables and stir well. This helps thicken the sauce later on. Then, add tomato purée, chopped tomatoes, and chicken stock, followed by paprika. Stir everything together until smooth. The sauce should start to thicken as it cooks.
4. Combining Sausages and Sauce
Return the browned sausages to the pan, ensuring they are fully covered by the sauce. This allows them to continue cooking slowly, absorbing the flavors of the sauce.
5. Simmering Gently
Cover the pan and let the casserole simmer gently for 30–35 minutes. Stir occasionally to prevent sticking. During this time, the sauce thickens naturally, and the sausages become tender and flavorful. For a thicker sauce, you can simmer uncovered for the last 10 minutes.
6. Seasoning and Serving
Taste the casserole and add salt and black pepper as needed. Serve your Mary Berry Sausage & Red Pepper Casserole with mashed potatoes, steamed rice, or crusty bread. A side of green beans or a simple salad adds freshness and balances the rich flavors.

Tips for the Perfect Casserole
- Brown the sausages properly – This adds flavor and keeps them juicy.
- Cook gently – Slow simmering prevents splitting and maintains texture.
- Taste before serving – Adjust seasoning as needed.
- Rest briefly – Allowing the casserole to rest for a few minutes helps flavors settle.
- Use a heavy pan – Ensures even cooking and prevents burning.
Healthier Version
For a lighter version, consider using lean sausages or chicken sausages and reduce the oil slightly. You can also increase the number of peppers or add extra tomatoes to bulk up the dish without adding heaviness.
Ingredient Substitutions
- Yellow or orange peppers can replace red peppers for a slightly different flavor.
- Smoked paprika adds depth and warmth.
- Vegetable stock can be used instead of chicken stock for a vegetarian-friendly version.
Creative Twists
- Add beans – Cannellini or butter beans make the casserole even more filling.
- Herb finish – Sprinkle fresh parsley or thyme before serving.
- Spicy kick – A pinch of chili flakes adds heat.
- Creamy touch – Stir in a spoon of crème fraîche for richness.
- Oven-baked – Transfer the casserole to an ovenproof dish and bake for a slightly different texture.
Storing and Reheating
- Refrigeration – Keep covered for up to 3 days.
- Freezing – Portion and freeze for up to 3 months.
- Reheating – Warm gently on the hob over low heat, adding a splash of stock if needed.
