One-Pan Chicken with Mushrooms and Kale

A simple, hearty one-pan chicken dish with earthy mushrooms, tender kale, and a mustardy stock sauce. Ready in under an hour and ideal for a satisfying weeknight dinner.

By Ricky Robinson Updated October 13, 2026

This one-pan chicken dish is exactly the kind of meal that earns its place in a regular weeknight rotation. Chicken thighs are seared until golden, then brought back together with mushrooms, kale, and a simple sauce built from chicken stock and wholegrain mustard. Everything cooks in the same pan, so there's minimal washing up and the flavours build nicely as you go.

Chicken thighs are the right cut for this. They hold up well to searing and stay juicy through the simmer, giving you tender, flavourful meat every time.

The kale wilts down quickly under the lid and picks up all the savoury juices from the pan. A squeeze of lemon at the end lifts the whole dish and balances the richness of the mustard sauce.

The mushrooms are worth cooking properly here. Give them a couple of minutes in the hot pan without moving them too much so they get some colour before you stir. That browning adds a depth of flavour that you lose if you rush this step. Once they're softened, the dried thyme and sage go in along with the paprika, and together they give the sauce a warm, earthy quality that works really well with the chicken.

The sauce itself is straightforward. Pour in the stock and mustard, scrape up the bits from the bottom of the pan, and let it come to a simmer before the chicken goes back in. You're not looking for a thick gravy here, more of a light, flavoursome broth that coats everything nicely. The kale goes in last, just long enough to wilt and steam through. Finish with the lemon juice and a scattering of finely chopped red chilli for a bit of colour and gentle heat.

This recipe serves four and keeps well in the fridge for a couple of days if you've got leftovers.

Ingredients

Equipment Needed

  • Knife
  • Large Frying Pan
  • Chopping Board

Instructions

  1. 1
    Heat a large pan over medium-high heat with a splash of olive oil. Season the chicken thighs with salt and black pepper. Sear for 5-6 minutes per side until golden brown and cooked through. Remove from the pan and set aside.
  2. 2
    In the same pan, add the mushrooms. Cook for 3 minutes without stirring to get a nice brown crust, then stir until softened. Add the dried thyme, dried sage, and paprika, stirring to combine.
  3. 3
    Add the onion and garlic to the pan, sautéing for 3-4 minutes until softened and fragrant.
  4. 4
    Pour in the chicken stock and wholegrain mustard, scraping up any brown bits from the bottom of the pan. Stir and bring to a gentle simmer. Return the chicken (and any resting juices) to the pan.
  5. 5
    Add the kale to the pan and cover with a lid. Leave for 2 minutes to allow the kale to steam and wilt down.
  6. 6
    Remove the lid and mix everything together for 1-2 minutes until the sauce thickens slightly. Finish with a squeeze of lemon juice. Serve scattered with the finely chopped red chilli.

Serving Suggestions

Serve straight from the pan with crusty bread to mop up the sauce, or alongside steamed rice or mashed potato. A simple green salad works well on the side if you want something lighter.
