Chicken Bake with Creamy Mushroom Sauce

Weeknight dinner that basically makes itself. Chicken thighs baked in a creamy mushroom sauce — just throw it together and let the oven do the work.

Instructions

  1. 1

    Cut the chicken thighs in half and place them in a greased ovenproof dish.

  2. 2

    Slice the mushrooms and cut the onion into wedges. Fry the mushrooms lightly in butter or oil, then fry the onion until it turns translucent.

  3. 3

    Mix together the mushroom sauce, water, and crème fraîche, then season with salt and pepper. Pour the sauce over the chicken thighs, and top with the fried mushrooms and onion.

  4. 4

    Put the dish in the oven at 200 °C for about 25 minutes.

Tips from the kitchen

  • Fry the mushrooms first in a hot pan and give them room. If you crowd them they steam and go grey instead of browning, and the browning is where the flavor comes from.
  • Mix the sauce, water, and crème fraîche in a bowl before pouring. Whisking it cold means no lumps once it hits the heat of the oven.
  • If you're using plain raw thighs rather than pre-grilled, check that the thickest piece hits 75°C with a thermometer. The 25 minutes is a guide, and bigger thighs sometimes need five more.
  • Cut the onion into wedges with a bit of the root left on each piece. They hold together while frying instead of falling apart into shreds.
  • Grease the dish properly. The crème fraîche sauce loves to stick to the corners, and a buttered dish saves you scrubbing later.

Ways to vary it

  • Throw a handful of fresh thyme or a couple of crushed garlic cloves into the pan with the onion if you want a bit more going on in the sauce.
  • Swap the chicken thighs for chicken breast if that's what you have, but cut the oven time back a touch since breast dries out faster than thigh.
  • A handful of grated cheese over the top in the last ten minutes gives you a browned crust if you like that.

Storage & leftovers

Keeps in the fridge for up to three days in a sealed container. The crème fraîche sauce can split a little when frozen, so I'd eat it fresh rather than freezing. Reheat gently in the oven at 150°C or in a pan over low heat, since high heat makes the sauce go grainy.

What to serve with it

Serve it over boiled potatoes or rice to catch the sauce. A simple green salad on the side keeps it from feeling too heavy.
