Instructions

  1. Step 1: Preheat oven to 425°F. Pat dry 4 bone-in, skin-on chicken thighs and season both sides with 1 tsp sea salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in an oven-safe skillet over medium-high heat until shimmering.

  7. Step 7: Stir in 1/2 cup heavy cream and 1 tsp fresh thyme leaves, simmer for 3-4 minutes until sauce thickens and coats the back of a spoon.
