Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss 1 lb halved Brussels sprouts with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper on a baking sheet. Roast for 20-25 minutes, stirring halfway through until tender and caramelized.
  2. Step 2: While Brussels sprouts roast, pat dry 2 boneless skinless chicken breasts (6 oz each). Season both sides with 1/2 tsp salt and 1/4 tsp black pepper.
  3. Step 3: Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 4 minced garlic cloves and 1 tsp lemon zest, sauté for 30 seconds until fragrant.
  4. Step 4: Add chicken breasts to the skillet and sear for 5-6 minutes per side, adjusting heat to prevent burning, until internal temperature reaches 165°F and the edges are golden.
  5. Step 5: Remove chicken from heat, drizzle with 2 tbsp lemon juice, and let rest for 5 minutes.
  6. Step 6: Serve chicken atop roasted Brussels sprouts, garnished with 2 tbsp chopped fresh parsley.
