Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Pat 2 chicken breasts (about 1 lb total) dry with paper towels and season with 1/4 tsp salt and 1/8 tsp black pepper.
  2. Step 2: In a small bowl, mix 2 tbsp Dijon mustard, 1/2 tsp garlic powder, and 1 tsp chopped fresh thyme.
  3. Step 3: Brush the mustard mixture evenly over both sides of the chicken breasts.
  4. Step 4: Heat 1 tbsp olive oil in an oven-safe skillet over medium-high heat until shimmering. Add chicken and sear for 2-3 minutes per side until golden brown.
  5. Step 5: Transfer skillet to oven and bake for 15-18 minutes until chicken reaches 165°F (74°C) internally.
  6. Step 6: While chicken bakes, toss 1 lb trimmed asparagus with 1 tsp olive oil, 1/4 tsp salt, and 1/8 tsp black pepper on a separate baking sheet. Roast for 12-15 minutes until tender-crisp.

How do I scale Mustard-Glazed Chicken with Roasted Asparagus for a different number of people?
