Ingredients

Instructions

  1. Step 1: Pat 1.5 lbs bone-in, skin-on chicken thighs dry with paper towels; season evenly with 1/2 tsp sea salt and 1/4 tsp black pepper.
  2. Step 2: Heat 3 tbsp unsalted butter in a slow cooker on high until melted, then sear chicken skin-side down for 3 minutes until golden brown, flipping once to sear the other side.
  3. Step 3: Add 6 minced garlic cloves and 8 oz sliced cremini mushrooms to the slow cooker, stirring to coat in butter; cook on high for 1 minute until garlic is fragrant.
  4. Step 4: Pour in 1/2 cup low-sodium chicken broth and add 1 tsp dried thyme; secure lid and cook on low for 4 hours until chicken reaches 165°F and mushrooms are tender.
  5. Step 5: Remove chicken thighs, then reduce sauce on high for 10 minutes until thickened enough to coat the back of a spoon, stirring occasionally.
