How to Make Mary Berry Slow Cooker Chicken Casserole
- Prepare the ingredients by cutting the bacon into small pieces and seasoning the chicken thighs with salt and pepper. Heat the oil in a pan and brown the chicken on medium-high heat. This helps develop a deeper flavour before slow cooking.
- Fry the bacon until it has crispy edges and the fat has rendered out. Add the onions and garlic, then cook gently until softened. Stir in the flour to create a smooth base for the sauce.
- Pour in the hot chicken stock and white wine, then add the thyme, sage, and bay leaves. Bring everything to a gentle simmer before transferring it to the slow cooker.
- Add the mushrooms and cover with the lid. Cook slowly until the chicken becomes tender and the flavours have developed into a rich casserole.
- Stir in the crème fraîche near the end of cooking to create a creamy sauce. If needed, use a cornflour slurry made with cornflour and cold water to thicken the sauce.
- Remove the bay leaves and sage sprigs before serving. Check the seasoning, garnish with parsley or crispy sage leaves, and serve hot with your favourite side dishes.
Expert Tips For Mary Berry Slow Cooker Chicken Casserole Recipe
For the best results with this casserole, I recommend preparing the ingredients properly and allowing enough time for slow cooking. A few simple adjustments can improve the flavour, texture, and final result, especially when adapting the recipe for different dietary needs.
- Make ahead by preparing the casserole up to a day in advance, as the flavours often become even richer after resting.
- Choose bone in and skin on thighs for extra flavour, but boneless and skinless chicken thighs can also work well.
- Brown the chicken before slow cooking to add colour and a deeper savoury taste.
- Avoid adding the crème fraîche too early, as adding it near the end helps maintain a smooth creamy texture.
- Use a meat thermometer to check that the chicken reaches a safe temperature of 165°F / 75°C.
- If you prefer a lighter option, replace crème fraîche with full fat sour cream or another suitable creamy alternative.
- For a low-carb meal, serve with cauliflower mash, celeriac mash, or steamed vegetables.
- The casserole freezes well, so store portions correctly for an easy future meal.
- To simplify the method and speed up cooking, prepare chopped ingredients in advance before starting.
- Add a small amount of xanthan gum if you need extra thickening while keeping the dish suitable for low-carb diets.
