Golden-seared chicken thighs simmer in a creamy brandy peppercorn sauce made in one skillet. Coarsely crushed rainbow peppercorns provide bold, balanced heat.
Lightly crush the 1½ tablespoons whole rainbow peppercorns with a mortar and pestle, keeping the pieces coarse rather than grinding them into powder. Set aside.
Season both sides of the 650 g boneless skinless chicken thighs with ½ teaspoon salt and ¼ teaspoon freshly ground black pepper.
Heat the 2 tablespoons extra virgin olive oil in a large skillet over medium-high heat. Sear the chicken thighs for 3–4 minutes per side until golden. Transfer them to a plate.
Reduce the heat to medium. Add the 2 tablespoons unsalted butter, 1 shallot, chopped, and 2 cloves garlic, minced. Cook for 1–2 minutes until softened. Stir in the crushed peppercorns and 3 fresh thyme sprigs, then cook for 30 seconds.
Carefully pour in the 60 ml brandy or Cognac and scrape the browned bits from the bottom of the skillet. Simmer for 1–2 minutes until slightly reduced.
Pour in the 240 ml low-sodium chicken broth and bring it to a boil. Reduce the heat and simmer for 5 minutes.
Stir in the 80 ml heavy cream and simmer gently for 1–2 minutes until the creamy peppercorn sauce thickens slightly.
Return the chicken thighs and any collected juices to the skillet. Spoon the sauce over the chicken and simmer for approximately 2 minutes, or until the thickest part reaches 165°F / 74°C.
Remove the thyme sprigs, sprinkle the chicken au poivre with 1 tablespoon chopped fresh parsley, and serve immediately with the sauce.
Notes
Crush, Don’t Grind: I keep the peppercorns coarse because finely ground pepper can make the sauce taste excessively sharp. Control the Peppery Heat: For a milder sauce, use slightly fewer peppercorns while preserving their coarse texture. Check the Chicken: Thighs vary in thickness, so check that the thickest piece reaches 165°F / 74°C rather than judging doneness from color alone. Simmer the Cream Gently: I keep the sauce at a gentle simmer so it thickens gradually and coats the chicken evenly.
