Full Ingredients

Chicken

• 8 bone-in, skin-on chicken thighs (about 2.5 lb / 1.1 kg)
• 1 tsp kosher salt (for chicken), plus more to taste
• 1/2 tsp freshly ground black pepper (for chicken), plus more to taste
• 2 tbsp extra-virgin olive oil

Basque Piperade Sauce

• 1 large yellow onion, thinly sliced
• 3 bell peppers (1 red, 1 yellow, 1 green), seeded and sliced into 1/2-inch strips
• 4 garlic cloves, thinly sliced
• 1 tbsp tomato paste
• 1/2 cup dry white wine (120 ml)
• 1 can crushed tomatoes, 14.5 oz (400 g)
• 1/2 cup low-sodium chicken stock (120 ml)
• 1 to 1.5 tsp piment d’Espelette (adjust to heat preference)
• 1 bay leaf
• 4 fresh thyme sprigs (or 1/2 tsp dried thyme)
• 1/2 tsp sugar (optional, to balance acidity)
• 1/2 tsp kosher salt and 1/4 tsp black pepper (for sauce), or to taste

Finish & Serve

• 1/2 cup pitted green olives (80 g), Castelvetrano recommended
• 1/4 cup loosely packed fresh basil leaves, torn, plus extra for garnish
• 1 tsp red wine vinegar (optional, for brightness)
• Crusty bread, buttered rice, or creamy polenta (for serving)

Step-by-Step Instructions

Step 1: Season the chicken and prep the vegetables

Pat the chicken thighs very dry with paper towels. Season all over with 1 tsp kosher salt and 1/2 tsp black pepper. Let them sit at room temperature for 10 minutes while you slice the onion, peppers, and garlic. This short rest helps the salt penetrate and promotes better browning.

Step 2: Sear the chicken until deeply golden

Heat a large Dutch oven or deep skillet (12-inch) over medium-high heat. Add the olive oil. Place chicken in the pan skin-side down and cook without moving until the skin is deep golden-brown and crisp, 8–10 minutes. Flip and cook 2 minutes on the second side. Transfer chicken to a plate, leaving the fat in the pan.

Step 3: Build the piperade base with peppers and onions

Reduce heat to medium. If there is more than 1–2 tbsp fat, spoon off the excess. Add the onion and peppers with a pinch of salt. Cook, stirring occasionally, until softened and lightly blistered at the edges, 8–10 minutes. Add the garlic and tomato paste; cook 1 minute, stirring, until fragrant and the paste darkens slightly.

Step 4: Deglaze and layer the flavors

Pour in the white wine and scrape up the browned bits on the bottom of the pan. Simmer until reduced by roughly half, 2–3 minutes. Stir in the crushed tomatoes, chicken stock, piment d’Espelette, bay leaf, thyme sprigs, and sugar (if using). Bring to a lively simmer. Taste and adjust salt and pepper.

Step 5: Simmer the chicken gently

Nestle the chicken back into the sauce, skin-side up. Reduce heat to maintain a gentle simmer. Cover and cook for 25 minutes, or until the chicken is very tender and registers about 175°F/79°C at the thickest point (165°F/74°C is minimum safe; 175°F yields more tender thighs).

Step 6: Thicken the sauce and finish with olives and basil

Uncover and simmer 8–10 minutes to reduce and thicken the sauce to a glossy, spoon-coating consistency. Remove the thyme stems and bay leaf. Stir in the olives and torn basil. Taste and adjust seasoning; add 1 tsp red wine vinegar if you’d like a touch of brightness.

Step 7: Rest and serve

Let the stew rest 5 minutes off the heat. Spoon the peppers and tomato sauce into shallow bowls, top with chicken, and garnish with extra basil. Serve with crusty bread, buttered rice, or creamy polenta to soak up the sauce.

Pro Tips

• Dry chicken equals better browning. Pat aggressively and give it room in the pan; sear in batches if needed.
• Keep the simmer gentle. A lively bubble can toughen the meat; soft blips give you tender chicken and a glossy sauce.
• Adjust heat with Espelette. Start with 1 tsp, then add up to 1.5 tsp for a warm, peppery glow without harsh heat.
• No piment d’Espelette? Use 1 tsp sweet paprika plus a pinch (to taste) of cayenne or Aleppo pepper.
• Want extra-crisp skin? Briefly broil just the chicken on a sheet pan 1–2 minutes while you finish reducing the sauce, then return it to the pot.

Variations

• With Bayonne ham: Sauté 3–4 oz diced Bayonne ham or prosciutto with the onions and peppers in Step 3 for a smoky, savory lift.
• Cider-kissed: Swap half the white wine with Basque-style dry cider for gentle fruitiness that pairs beautifully with peppers.
• Different cuts: Use drumsticks or bone-in thighs/drumsticks mix; simmer times remain similar. Boneless thighs work too; reduce covered simmer to about 15–18 minutes.

Storage & Make-Ahead

Refrigerate leftovers in an airtight container for up to 4 days; the flavors deepen overnight. Freeze up to 3 months (without the basil for best color); thaw in the fridge and reheat gently on the stovetop with a splash of water or stock. You can make the piperade sauce base a day ahead, then reheat, add chicken, and simmer just before serving. Add fresh basil at the end for a bright finish.
