Instructions

  1. Step 1: Pat dry 2 chicken breasts and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat and sear chicken for 5-6 minutes per side until golden brown and cooked through; remove and keep warm.
  2. Step 2: In the same skillet, add 1 tbsp olive oil, then add 1 medium thinly sliced yellow onion. Sauté over medium heat for 10 minutes, stirring occasionally, until the onions are deeply caramelized and fragrant.
  3. Step 3: Add 8 oz sliced shiitake mushrooms and 3 minced garlic cloves to the onions, cooking for 5 minutes until mushrooms soften and release moisture.
  4. Step 4: Stir in 1 tsp smoked paprika and cook for 1 minute to toast the spice and bring out the smoky aroma.
  5. Step 5: Pour in 1/4 cup dry white wine to deglaze the pan, scraping up browned bits. Let the wine reduce for 2 minutes.
  6. Step 6: Add 1/2 cup chicken broth and 1 tbsp chopped fresh thyme. Simmer for 5 minutes until the sauce thickens slightly and coats the back of a spoon.
  7. Step 7: Return chicken to the pan to warm through for 2 minutes, spooning the sauce over the top. Serve immediately.
