Step 1

To marinate the chicken, put the chicken thighs to a large bowl. Then add 1 tablespoon of olive oil, Italian seasoning, half teaspoon of salt, pepper, lemon juice, dijon mustard, and stone ground mustard.

Step 2

Toss the chicken so that everything is coated evenly, then cover with cling film and marinate in the fridge for at least 30 minutes.

Step 3

Place trimmed and halved brussels sprouts on a sheet pan, followed by red onion, and garlic cloves.

Step 4

Drizzle with the remaining olive oil, and season with the remaining salt and pepper. Toss so that everything is well coated.

Step 5

Using tongs, place marinated chicken thighs skin side up on the sheet pan. Bake uncovered at 400°F (200°C) for 30-35 minutes. Then crisp the skin up and brown it under the broiler for a few minutes.
