Very delicious weeknight meal for the family or for just you! It’s easy and all in one pan with Brussels and red onions. Easy to put together, just try and marinate chicken for how ever long you can — at least 30 minutes and up to 48 hours in the fridge. The marination process is key — I did it for about 6 hours in fridge and removed from fridge to bring to room temperature before cooking.
I don’t recommend using chicken breasts in this recipe as they tend to dry out. So use chicken thighs to get juicy and delicious tasting chicken.
Enjoy this meal bursting with flavor!
You’ll need a rimmed sheet pan, a large glass bowl, a small bowl, and I recommend using a kitchen thermometer which if you don’t have one you should own for cooking chicken.
Ingredients:
2 pounds of chicken thighs ( about 6 ) bone in , skin on
3 Tablespoons Olive Oil ( divided)
1 Tbsp. Italian Seasoning ( available dry in most supermarkets)
2 tsp. Kosher Salt
app. 1/2 ground black pepper
2 Tbsp. fresh Lemon Juice
1 heaping Tbsp. Dijon Mustard
1 heaping Tbsp. stone ground Mustard
app. 10 oz. Brussels sprouts trimmed and cut in half if very large cut in 1/4s and if very small leave whole
1 Red Onion cut into 8 wedges
6 cloves garlic minced
Directions:
To marinate the chicken, pat dry the chicken and put in a large bowl. In a smaller bowl add 1 Tbsp. Olive Oil, Italian seasoning, 1 teaspoon kosher salt, freshly ground black pepper, lemon juice , dijon mustard, stone ground mustard. I whisk it all together and pour over the chicken in bowl and with clean hands squish around the chicken and cover and place in the fridge. Take out of fridge and bring to room temperature before putting into the oven (probably a 1/2 hour)
Pre heat oven to 400 degrees
I spray baking sheet with cooking spray first, then place trimmed and halved Brussels sprouts on the sheet pan. I then put 6 garlic cloves in mini processor and add 2 Tablespoons of Olive oil to processor and when this is done pour over the Brussels and coat well and sprinkle the remaining 1 tsp. kosher salt and some freshly ground black pepper to them.
Place marinated chicken thighs skin side up on the sheet pan moving Brussels and onions around so the chicken touches the sheet . (see photo)
Bake uncovered at 400 degrees F. for 30 minutes then crisp the skin up and brown it under the broiler. I did it for about 4 minutes till I obtained a nice crispy skin. Check chicken temperature before serving but it should be 165 and perfect!
Served over rice and it was delicious.
