Instructions

  1. Step 1: Pat dry 2 boneless skinless chicken breasts (6 oz each) and season both sides with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add the chicken breasts and sear for 5 minutes on each side until golden brown and cooked through, about 165°F internal temperature. Remove and set aside.
  3. Step 3: In the same skillet, add 1 medium thinly sliced yellow onion and sauté over medium heat for 10 minutes until caramelized, stirring occasionally to prevent burning.
  4. Step 4: Add 2 minced garlic cloves to the onions and cook for 30 seconds until fragrant.
  5. Step 5: Pour in 1/2 cup chicken broth and scrape the browned bits from the bottom of the pan. Simmer for 3 minutes until the sauce reduces slightly.
  6. Step 6: Return the chicken breasts to the skillet, top each with 2 oz sliced aged cheddar cheese, and cover the skillet with a lid. Reduce heat to low and cook for 2-3 minutes until the cheese melts.
  7. Step 7: Remove skillet from heat, stir in 1 tbsp butter and 1 tsp chopped fresh thyme into the sauce for richness and aroma. Serve chicken topped with caramelized onions and pan sauce.

How do I store leftover Pan-Seared Chicken with Aged Cheddar and Caramelized Onion?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep salt from drying out.

Can I substitute ingredients in Pan-Seared Chicken with Aged Cheddar and Caramelized Onion?
