Instructions

Step 1: Pat dry 2 boneless skinless 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 until shimmering.
Step 2: Add the chicken breasts and sear for 5-6 minutes on each side until golden brown and cooked through (internal temp 165°F). Transfer chicken to a plate and cover loosely with foil.
Step 3: Reduce heat to medium and add 2 tbsp unsalted butter to the skillet. Once melted, add 8 oz sliced button mushrooms and sauté for 5 minutes until browned and softened.
Step 4: Stir in 2 finely chopped shallots and 3 minced garlic cloves; cook for 1-2 minutes until fragrant but not browned.
Step 5: Pour in 3/4 cup stout beer and 1/2 cup chicken broth, scraping up any browned bits from the pan. Add 1 tsp fresh thyme leaves, then simmer for 6-8 minutes until the sauce reduces and thickens slightly.
Step 6: Stir in 1/4 cup heavy cream and simmer for another 2 minutes until the sauce coats the back of a spoon; return the chicken breasts to the pan to warm through.
Step 7: Sprinkle 1 tbsp chopped fresh parsley over the dish before serving. Serve chicken with the mushroom stout sauce spooned over the top.
