Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large skillet over medium heat. Add 1 thinly sliced medium yellow onion and cook, stirring occasionally, for 15 minutes until deeply caramelized and golden brown.
  2. Step 2: Remove onions from skillet and set aside. Add 1 tbsp olive oil and 2 tbsp unsalted butter to the same skillet, then season 2 boneless skinless chicken breasts with 1 tsp salt and 1/2 tsp black pepper. Sear chicken over medium-high heat for 5-6 minutes per side until golden and cooked through.
  3. Step 3: Remove chicken and reduce heat to medium. Add 4 minced garlic cloves and 1 tbsp fresh thyme leaves to the skillet, sauté for 30 seconds until fragrant.
  4. Step 4: Pour in 1/2 cup chicken broth and scrape the browned bits from the pan, simmer for 2 minutes until sauce slightly thickens.
  5. Step 5: Return caramelized onions and chicken breasts to the skillet, spoon sauce over chicken, and sprinkle 2 tbsp chopped fresh parsley before serving.

Frequently asked questions

How do I store leftover Sautéed Chicken with Caramelized Onions and Garlic Herb Sauce?

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 large yellow onion from drying out.

Can I substitute ingredients in Sautéed Chicken with Caramelized Onions and Garlic Herb Sauce?
