Ingredients

  • 5 chicken thighs, skin on, bone in (about 200g / 7 oz each)
  • Salt and pepper
  • 2 tsp olive oil
  • 2 garlic cloves, minced
  • 1 medium onion, finely chopped
  • 1 each red and green capsicum (bell pepper), sliced
  • ½ cup / 125 ml white or red wine (dry white recommended)
  • 800 g / 28 oz can crushed tomato
  • ¾ cup / 185 ml water
  • 1 tsp red pepper flakes (adjust to taste)
  • ¾ cup black olives, pitted (or ⅓ cup sliced)
  • 2 tbsp baby capers
  • Salt and pepper to taste
  • ¼ cup finely chopped parsley

Instructions

  1. Step 1: Use a small knife to prick about five gashes into the skin of each chicken thigh. Sprinkle both sides with salt and pepper.
  2. Step 2: Place the chicken skin side down in a cold large non-stick skillet, then turn the heat to medium-high. As the pan heats, fat will render through the skin.
  3. Step 3: Cook for 4–5 minutes until the skin is golden and crispy. Flip the chicken and cook the other side for 3 minutes.
  4. Step 4: Remove the chicken to a plate. Discard the fat from the pan without scraping. Return the pan to the stove.
  5. Step 5: Add olive oil, garlic, and onion to the pan. Cook for 1 minute, then add the sliced capsicum and cook for 2 more minutes.
  6. Step 6: Pour in the wine and bring to a simmer, stirring and scraping the pan to loosen browned bits. Cook until most of the wine has evaporated and the smell has faded.
  7. Step 7: Stir in the crushed tomato, water, and red pepper flakes. Adjust heat to maintain a steady, energetic simmer.
  8. Step 8: After about 5 minutes, mix in the olives and capers. Taste the sauce and season with salt and pepper as needed.
  9. Step 9: Return the chicken to the sauce, placing it so the skin stays above the sauce. Cook for another 5 minutes.
  10. Step 10: Sprinkle with chopped parsley before serving. Serve with crusty bread or toss half the sauce with pasta, using the rest with chicken.

Tips & Variations

  • For a lighter option, substitute chicken thighs with skin-on chicken breasts, adjusting cooking time accordingly.
  • If you prefer no wine, use chicken broth or extra water with a splash of lemon juice for acidity.
  • Adjust the red pepper flakes to control the heat level—start with less if you’re sensitive to spice.
  • Add a handful of chopped fresh basil or oregano for an extra herbal note.
  • Use Kalamata olives for a richer, more tangy flavor in the sauce.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat or in the microwave until warmed through. This casserole also freezes well; thaw overnight in the fridge before reheating.

How to Serve

A black skillet holds a rich, deep red tomato sauce layer with chunks of olives and bell peppers, creating a textured and colorful base. On top, there are three pieces of golden brown, crispy chicken thighs with a slightly shiny, crunchy skin. Thin slices of bright red chili peppers are scattered across the chicken and sauce, adding sharp color contrast, along with a sprinkle of finely chopped green herbs for freshness. A silver spoon partly lifts one piece of chicken, showing its tender side beneath the crisp top. The skillet rests on a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use boneless chicken instead of bone-in thighs?

Yes, boneless chicken thighs or breasts work fine, but cooking times may be shorter. Be sure to cook until the chicken reaches a safe internal temperature.

Is it necessary to prick the chicken skin with a knife?

Pricking the skin helps the fat render out during cooking, making the skin crisper and preventing it from becoming soggy in the sauce. It also allows seasoning to penetrate better.

Ingredients

Scale

Chicken

  • 5 chicken thighs, skin on, bone in (about 200g / 7 oz each)
  • Salt and pepper, to taste
  • 2 tsp olive oil

Vegetables & Aromatics

  • 2 garlic cloves, minced
  • 1 medium onion, finely chopped
  • 1 red capsicum / bell pepper, sliced
  • 1 green capsicum / bell pepper, sliced

Liquids & Sauce

  • ½ cup / 125 ml white or red wine (dry white preferred)
  • 800 g / 28 oz can crushed tomato
  • ¾ cup / 185 ml water (use empty tomato can to measure)

Seasonings & Garnishes

  • 1 tsp red pepper flakes (adjust to taste)
  • ¾ cup black olives, pitted (or 1/3 cup sliced)
  • 2 tbsp baby capers
  • Salt and pepper, to taste
  • ¼ cup finely chopped parsley

Instructions

  1. Prepare Chicken: Use a small knife to prick 5 or so gashes into the skin of each chicken thigh. Season both sides generously with salt and pepper.
  2. Render Chicken Skin: Place the chicken thighs skin side down in a cold large non-stick skillet. Turn the stove on to medium-high heat. As the pan heats, the fat under the skin will melt through the gashes creating crispy skin.
  3. Cook Chicken Skin Side: Cook the chicken for 4–5 minutes or until the skin is golden and crispy. Flip the chicken and cook the other side for 3 minutes.
  4. Remove Chicken & Discard Fat: Transfer the chicken to a plate. Carefully discard the rendered fat from the pan but avoid scraping the pan to keep the browned bits intact. Return the pan to the stove.
  5. Sauté Aromatics: Add olive oil, minced garlic, and chopped onion to the skillet. Cook for 1 minute until fragrant, then add the sliced red and green capsicum. Cook for an additional 2 minutes.
  6. Deglaze with Wine: Pour in the wine and bring to a simmer. Stir the mixture, scraping up the flavorful browned bits from the bottom of the pan until most of the wine has evaporated and the wine aroma has lessened.
  7. Add Tomato Sauce Base: Stir in the crushed tomato, water, and red pepper flakes. Adjust heat to maintain a steady, energetic simmer—bubbling but not rapid.
  8. Incorporate Olives and Capers: After about 5 minutes of simmering, stir through the black olives and baby capers. Taste the sauce and season with salt and pepper as needed.
  9. Simmer Chicken in Sauce: Carefully nestle the chicken thighs into the sauce skin side up, making sure the skin remains above the liquid to keep it crisp. Cook for another 5 minutes to allow flavors to meld and chicken to finish cooking.
  10. Finish and Serve: Sprinkle finely chopped parsley over the finished casserole. Serve hot with crusty bread or toss half the sauce with pasta to accompany the chicken.

Notes

  • You can substitute chicken breasts for thighs if preferred, but thighs provide better flavor and moisture.
  • If you don’t have wine, substitute with extra water mixed with a splash of vinegar or chicken broth for depth.
  • Adjust red pepper flakes to your preferred spice level.
  • For a complete meal, serve with crusty Italian bread or your favorite pasta.
  • Discarding rendered chicken fat keeps the sauce from becoming overly greasy.
