Equipment

  • Ovenproof casserole dish
  • Sharp knife
  • Wooden spoon
  • Measuring cups and spoons
  • Cutting board

Ingredients
  

Chicken Casserole

  • salt and pepper to season
  • 8 strips smoked streaky bacon diced
  • 200 g mushrooms sliced
  • 1 g large onion finely diced
  • 8 chicken thighs
  • 250 g full fat creme fraiche or sour cream
  • 120 ml dry white wine
  • ½ tsp ground black pepper
  • ½ tsp minced garlic
  • 120 ml hot chicken stock from a stock cube
  • 1 tsp sunflower oil
  • ½ tsp salt
  • 2 bay leaves
  • 1 tsp xanthan gum or 2 tsp cornflour diluted in a little cold water
  • 1 tsp dried thyme or mixed herbs
  • 4 fresh sage leaves or small sage sprigs

Fried Sage

  • large fresh sage leaves
  • 1 tbsp unsalted butter

Instructions
 

  • Season the chicken thighs generously with salt and pepper.
  • Heat oil in a skillet over high heat, then brown the chicken on both sides before setting it aside and draining any excess oil.
  • In the same pan, cook the bacon over medium heat until the fat begins to render.
  • Add the onions and garlic, stirring for about five minutes until the onions soften and the bacon turns crispy at the edges.
  • Stir in the mushrooms, additional salt, pepper, and dried herbs, cooking until the mushrooms are browned.
  • Pour in the white wine and chicken stock, then add the sage and bay leaves.
  • Return the chicken to the pan, bring everything to a gentle simmer, and transfer to a preheated 160°C (325°F) oven.
  • Cover and cook for 20 minutes, then uncover and cook for another 10 minutes.
  • Alternatively, simmer on the stove over low heat for about 20 minutes until the chicken is fully cooked.
  • Stir in the crème fraîche and, if needed, thicken the sauce with xanthan gum or a little diluted cornflour, allowing it to simmer briefly.
  • In a separate pan, melt butter and fry the sage leaves until crispy, then drain them on a paper towel.
  • Discard the bay leaves, adjust the seasoning, and serve topped with crispy sage leaves alongside mashed potatoes or a low-carb alternative.

Notes

  • Browning the chicken well adds depth of flavor to the dish, so don’t rush this step.
  • Use dry white wine for a richer taste, or substitute with extra chicken stock for an alcohol-free version.
