Ingredients

Instructions

  1. Step 1: Pat 1.5 lbs boneless chicken thighs dry, season with salt and pepper, and sear in a large ovenproof skillet over medium-high heat for 5 minutes per side until golden brown; transfer to a plate.
  2. Step 2: Dice 8 oz sliced cremini mushrooms and 1 medium chopped shallot, then cook in the skillet with 2 tbsp butter until mushrooms release liquid and brown, about 8 minutes.
  3. Step 3: Stir 3 tbsp all-purpose flour into mushroom mixture, then slowly whisk in 1.5 cups chicken broth and 1 cup heavy cream. Simmer for 5 minutes until thickened and bubbling.
  4. Step 4: Return chicken to skillet, nestling it into the sauce, and sprinkle with 2 tbsp fresh thyme and 1 tsp paprika. Cover with a lid and bake at 375°F for 25 minutes until chicken reaches 165°F.
  5. Step 5: Remove lid, scatter 1/2 cup panko breadcrumbs over the top, and bake uncovered for 8-10 minutes until breadcrumbs are golden and crisp.
