Chicken casserole with bacon and mushrooms in a creamy sauce

Mary Berry is the queen of unfussy cooking and baking. I love her simple recipes and straightforward instructions. This chicken and herb casserole is a Mary Berry favourite!

You can’t go wrong with tender chicken thighs cooked with white wine, bacon, mushrooms and herbs! The finishing touch, creme fraiche, turns this one-pot recipe into something truly special.

Mary Berry’s Chicken Casserole is topped with crispy fried sage leaves which I normally would go the extra mile for but they are not essential!

If you follow a low carb / Keto diet, make sure to use xanthan gum to thicken the sauce. Serve with cauliflower or celeriac mash and steamed vegetables.

Here’s what you will need

You will need an oven-safe casserole dish for this recipe. I have rejigged the method of this recipe to simplify it and speed it up a bit. You can cook the casserole on the stove or partially in the oven.

  • Chicken thighs: I used bone in and skin on thighs but you can use boneless and skinless if you prefer
  • Smoked streaky bacon
  • Onions and garlic
  • Mushrooms – small white button mushrooms or chestnut mushrooms
  • White wine – dry white wine such as Sauvignon Blanc or Pinot Gris
  • Chicken stock from a cube
  • Creme fraiche or thick double cream
  • A little cornflour or xanthan gum to thicken the sauce if needed
  • Fresh sage leaves, dried thyme, bay leaves

Take the lid off and continue to cook for a further 10 minutes. Alternatively continue to cook the casserole on the stove over low heat until the chicken is cooked through.

    Why do you give instructions to cook in the oven if you haven’t tried it? How did you cook it?

        Thank you for your reply, Lucy.
        What temperature do you set the oven, and why not include that information in the method?
        I am also wondering why you told two other people that you hadn’t cooked the casserole in the oven.

          Hi Kate, thanks for pointing this out, there was some confusion here as the recipe was updated recently and clearly an error crept through. You can cook the casserole entirely on the stove or transfer it midway through to an oven. I have clarified in the instructions

      you state that this Mary berry recipe is not suitable for freezing due to its creme fraiche. but in a similar recipe with creme fraiche ms Berry tells us that it freezes well!

        You can freeze it if you like – I don’t like the texture when it is reheated xx
