Chicken in Mustard and Rosemary Sauce

Chicken in Mustard and Rosemary Sauce

with roast potatoes and broccoli

The sauce that coats the juicy chicken in this recipe is a multifaceted affair. It's creamy with a hint of heat—owing to the inclusion of mustard—with the earthy herbaceousness of rosemary adding yet another layer. Crispy potatoes and tender broccoli are also great pairings for this delicious dressing.

Baking Sheet with Baking Paper


Cook the Potatoes
  • Preheat your oven to 240°C/220°C fan/gas mark 9.
  • Cut the potatoes into 2cm chunks.
  • Pick the rosemary leaves and roughly chop.
  • Add the potatoes to a lined baking tray and toss with half the rosemary, saltpepper and a drizzle of oil.
  • Once the oven is hot roast on the top shelf until golden, 25-35 mins. Turn the tray halfway through.
Roast the Broccoli
  • Peel and grate the garlic (or use a garlic press).
  • Trim the tip of the broccoli. Cut head into small florets and stem into 2cm pieces.
  • Add the broccoli to a lined baking tray and toss with salt, pepper and a drizzle of oil.
  • When the potatoes have been cooking for 15 mins, place the broccoli on the middle shelf of the oven and roast until crispy around the edges, 10-12 mins.
Prep the Chicken
  • Meanwhile, place a hand flat on top of the chicken breast and slice through horizontally to make two thin steaks. IMPORTANT: Wash hands and equipment after handling raw chicken and its packaging.
  • Repeat with the other breast(s).
  • Season the chicken with salt and pepper.

TIP: Notice a stronger smell from your chicken? Don’t worry, this is normal due to packaging used to keep it fresh.

Fry the Chicken
  • Place a large pan over medium-high heat with a drizzle of oil.
  • Once hot, lay in the chicken, season to taste with salt and pepper and cook until golden brown and crispy, 3-6 mins on each side.
  • Once cooked, remove from the pan and cover to keep warm. IMPORTANT: Chicken is cooked when no longer pink in the middle.

TIP: Cook in batches if your pan is getting crowded.

Make the Sauce
  • Return the pan to medium-low heat and add the creme fraiche.
  • Season with pepper then stir in the stock, garlic, half the mustard (double for 4p), and remaining rosemary.
  • Cook, stirring, until everything is combined and the sauce is nice and smooth, 3-5 mins.
  • Once ready, add the chicken back into the pan to coat in the sauce and warm through, 1-2 mins.
Finish and Serve
  • Divide the broccoli and potatoes between plates. 
  • Plate the chicken alongside.
  • Finish with a drizzle of the creamy mustard rosemary sauce.
