Why You’ll Love This Recipe
These spicy chicken thighs develop incredible flavor during slow roasting. Harissa and tomato paste create a rich sauce, while brown sugar adds just enough sweetness to balance the heat. Olives provide a salty, savory contrast, and fresh tomatoes become soft and juicy as they roast.
The preparation is also refreshingly simple. Everything comes together in one baking dish, and bone-in chicken thighs stay tender and succulent during the longer roasting time. The fresh gremolata added at serving makes these chicken thighs with olives taste bright and beautifully balanced.
Ingredients

For the chicken:
- 8 bone-in chicken thighs, trimmed
- 8 garlic cloves
- 1 cup mixed olives
- 1/4 cup tomato paste
- 1 tablespoon harissa paste
- 1 tablespoon brown sugar
- 1/2 cup chicken stock
- Salt, to taste
- Cracked black pepper, to taste
- 14 ounces Roma tomatoes, preferably on the vine
For the gremolata:
- 1/2 cup flat-leaf parsley, chopped
- 1/2 cup cilantro leaves, chopped
- 1 tablespoon lemon juice
- 1 tablespoon lemon zest
- 2 garlic cloves, minced
Instructions
- Preheat the oven to 350°F (175°C).
- Prepare the gremolata by combining the chopped parsley, cilantro, lemon juice, lemon zest, and minced garlic in a small bowl. Mix well and set aside.
- Arrange the chicken thighs, 8 garlic cloves, and mixed olives in a large baking dish.
- In a small bowl, stir together the harissa paste, tomato paste, brown sugar, and chicken stock until combined.
- Spoon the harissa mixture evenly over the chicken, garlic, and olives. Season with salt and cracked black pepper.
- Cover the baking dish tightly with foil and roast for 1 hour.
- Increase the oven temperature to 400°F (200°C). Carefully remove the foil and arrange the Roma tomatoes around the chicken.
- Return the uncovered Harissa Chicken Thighs to the oven and roast for another 30 minutes, or until the chicken is fully cooked and the tomatoes are tender and lightly caramelized.
- Check that the thickest part of the chicken has reached an internal temperature of at least 165°F (74°C), avoiding contact with the bone when measuring.
- Spoon some of the tomato-harissa sauce over the chicken and finish generously with the prepared gremolata before serving.

Tips & Tricks
For especially flavorful baked chicken thighs, use bone-in thighs because they remain juicy during the extended roasting time. Arrange them in a single layer whenever possible so they cook evenly.
Harissa pastes vary considerably in heat, so adjust the amount according to the brand and your preferred spice level. For a milder dinner, start with less harissa. For extra heat, increase it gradually.
Green, black, or mixed olives all work well. If your olives are particularly salty, season the chicken lightly at first and adjust the salt after cooking.
You can also prepare the gremolata while the chicken roasts. Keep it chilled until serving so the herbs and lemon remain fresh and vibrant.

Notes
For a less spicy version, reduce the harissa paste while keeping the tomato paste and chicken stock unchanged.
Boneless chicken thighs may also be used, but the cooking time will need to be reduced. Always use the internal temperature rather than the original cooking time as the final guide for doneness.
Serve these Mediterranean chicken thighs with couscous, rice, roasted potatoes, or warm flatbread to soak up the tomato and harissa sauce. A simple cucumber salad or leafy green salad also makes a refreshing side.

FAQ
What do Harissa Chicken Thighs taste like?
They have a savory, tomato-rich flavor with smoky, earthy heat from harissa. Olives add a salty bite, while lemon and fresh herbs in the gremolata provide a bright finish.
What is harissa paste?
Harissa is a North African chili paste typically made with red peppers, spices, garlic, and oil. Its exact heat and flavor vary by brand, so tasting your harissa before adding it is helpful.
Can I make this harissa chicken recipe less spicy?
Yes. Simply reduce the amount of harissa paste. You can keep the remaining sauce ingredients the same for a milder dish that still has plenty of flavor.
Which olives are best for chicken thighs with olives?
A combination of green and black olives gives the dish interesting color and flavor, but either variety can be used on its own. Choose olives you enjoy eating because their flavor becomes part of the roasting sauce.
Can I use boneless chicken thighs?
Yes, but boneless thighs generally cook faster than bone-in chicken. Adjust the roasting time accordingly and make sure the chicken reaches a safe internal temperature of 165°F (74°C).
What should I serve with spicy chicken thighs?
Couscous, basmati rice, roasted potatoes, flatbread, or a simple salad are all good options. Grains and bread are particularly useful for enjoying the flavorful harissa-tomato sauce.
Storage
Store leftover chicken, tomatoes, olives, and sauce in an airtight container in the refrigerator for up to 3–4 days. For the freshest flavor, keep leftover gremolata in a separate covered container.
For longer storage, freeze the cooked chicken and sauce in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheat gently in a covered baking dish at 350°F (175°C) until thoroughly hot. Individual portions can also be reheated in the microwave. Add fresh gremolata after reheating rather than before.
