Instructions

  1. Step 1: Pat dry 2 boneless skinless chicken breasts (about 6 oz each) and season with 1 tsp salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add chicken and cook for 5-6 minutes per side until golden brown and cooked through, then transfer to a plate and keep warm.
  2. Step 2: In the same skillet, add 1 tbsp olive oil and 1 medium thinly sliced yellow onion. Sauté over medium heat for 10 minutes, stirring occasionally, until onions are deeply caramelized and golden.
  3. Step 3: Add 8 oz sliced cremini mushrooms and 3 minced garlic cloves to the onions. Cook for 5 minutes until mushrooms release moisture and begin to brown.
  4. Step 4: Pour in 1/4 cup dry white wine and cook for 2 minutes, scraping the browned bits from the pan until the wine reduces by half.
  5. Step 5: Add 1/2 cup chicken broth and 1 tsp fresh thyme leaves, simmering for 3-4 minutes until the sauce thickens slightly.
  6. Step 6: Stir in 1 tbsp unsalted butter until melted and the ragout is glossy. Return the chicken to the skillet to warm for 1 minute, then serve topped with the onion and mushroom ragout.

Frequently asked questions

How long does Pan-Seared Chicken with Carmelized Onion and Mushroom Ragout take to make?

How do I store leftover Pan-Seared Chicken with Carmelized Onion and Mushroom Ragout?

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 olive oil from drying out.

Can I substitute ingredients in Pan-Seared Chicken with Carmelized Onion and Mushroom Ragout?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut).

How do I scale Pan-Seared Chicken with Carmelized Onion and Mushroom Ragout for a different number of people?

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.
