Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Pat 1 lb boneless chicken thighs dry and season with 1/2 tsp salt and 1/4 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat. Add chicken thighs and cook for 4-5 minutes per side until golden brown. Remove chicken and set aside.
  3. Step 3: Add 2 sliced carrots and 1 cup frozen peas to the skillet. Cook for 3 minutes until carrots soften slightly. Stir in 2 minced garlic cloves and 1 tsp chopped thyme.
  4. Step 4: Pour in 1/2 cup chicken broth and simmer for 2 minutes until liquid reduces slightly.
  5. Step 5: Place cooked chicken on top of vegetables. Sprinkle 1/2 cup breadcrumbs and 2 tbsp grated parmesan cheese over the top.
  6. Step 6: Bake uncovered for 20-25 minutes until chicken is cooked through (internal temperature 165°F) and breadcrumbs are golden brown. Let rest for 5 minutes before serving.
