Ingredients

Instructions

  1. Step 1: Pat dry 2 boneless skinless chicken breasts and season with 1 tsp salt and 1/2 tsp black pepper evenly on both sides. Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering.
  2. Step 2: Add the chicken breasts to the skillet and sear for 5-6 minutes on the first side without moving, until golden brown and edges are crispy. Flip and cook an additional 4-5 minutes until cooked through and juices run clear, then remove from the pan and keep warm.
  3. Step 3: Reduce heat to medium and add 1 large thinly sliced yellow onion to the same skillet. Cook for 8-10 minutes, stirring occasionally, until the onions are deeply golden and caramelized.
  4. Step 4: Stir in 2 minced garlic cloves and 1 tbsp fresh thyme leaves, cooking for 30 seconds until fragrant. Pour in 1/2 cup chicken broth and scrape the bottom of the pan to deglaze, simmering until the sauce thickens slightly, about 3 minutes.
  5. Step 5: Remove from heat and whisk in 1 tbsp unsalted butter until melted and glossy. Return the chicken breasts to the pan to coat in the sauce before serving.

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
