This Portuguese-style piri-piri chicken roasts bone-in thighs and potatoes with a garlicky, tangy chile sauce, so the main and side cook together. The heat is easy to adjust, and versions vary by cook; this one uses a practical pantry-friendly substitute for hard-to-find piri-piri chiles.
Ingredients
- 8 bone-in, skin-on chicken thighs, about 3 lb (1.36 kg)
- 1½ lb (680 g) small Yukon Gold or red potatoes, cut into 1-inch (2.5 cm) pieces
- 1 medium yellow onion, about 5 oz (150 g), cut into wedges
- ¼ cup (60 ml) olive oil for the sauce
- 1 tbsp (15 ml) olive oil for the potatoes
- 5 garlic cloves, about ½ oz (15 g), peeled
- 2 tbsp (30 ml) fresh lemon juice, plus 1 lemon cut into wedges for serving
- 1 tbsp (15 ml) red wine vinegar
- 1 tbsp (7 g) sweet or smoked paprika
- 1 tsp (1 g) dried oregano
- 2 small dried piri-piri or African bird’s-eye chiles, about 1 g, stemmed; or ½ tsp (1 g) crushed red pepper plus a pinch of cayenne
- 1½ tsp (9 g) fine salt, divided
- ½ tsp (1 g) freshly ground black pepper
- ¼ cup (10 g) chopped fresh cilantro, for serving
Instructions
- Set a rack in the center of the oven and heat it to 425°F (220°C). Pat the chicken thighs dry with paper towels; dry skin browns more readily. If the potatoes are larger than bite-size, cut them into roughly even pieces so they finish at the same time.
- Make the piri-piri sauce: in a blender or small food processor, combine the ¼ cup (60 ml) olive oil, garlic, lemon juice, vinegar, paprika, oregano, chiles, ½ tsp (3 g) of the salt, and the black pepper. Blend until the garlic and chile are finely chopped and the sauce looks cohesive. Without a blender, mince the garlic and chiles very finely, then whisk everything together.
- Transfer 2 tbsp (30 ml) of the sauce to a small clean bowl and set it aside for serving. Put the chicken in a shallow dish and rub the remaining sauce over all sides, working a little beneath the skin without tearing it. Cover and refrigerate for 30 minutes. Do not leave raw chicken marinating on the counter.
- While the chicken marinates, toss the potatoes and onion with the remaining 1 tbsp (15 ml) olive oil and ½ tsp (3 g) salt. Spread them in a single layer in a large rimmed baking sheet or roasting pan. Roast for 15 minutes, giving the oven time to get the potatoes started before adding the chicken.
- Take the pan from the oven and turn the potatoes and onion. Arrange the thighs skin-side up among the vegetables, leaving a little space around each piece. Spoon any marinade left in the dish over the chicken, but do not use the clean sauce reserved for serving on raw poultry.
- Roast for about 35 minutes, until the potatoes are tender and the chicken skin is well browned. Start checking the thighs after 30 minutes because size and oven performance vary. Check the thickest part of each thigh with an instant-read thermometer, avoiding the bone; the USDA FSIS safe minimum temperature for poultry is 165°F (74°C). If the chicken reaches temperature before the potatoes are tender, move the chicken to a clean plate and continue roasting the vegetables.
- Let the chicken rest for 5 minutes, then scatter the cilantro over the pan. Serve with the reserved clean sauce and lemon wedges. If you prefer a milder finish, offer the sauce at the table rather than spooning it over every portion.
Tips
- Use the right chile for your heat preference. Piri-piri, also called African bird’s-eye chile, can be quite hot and is not stocked everywhere. Crushed red pepper with a pinch of cayenne is a useful substitute; it gives a similar sharp warmth but a less distinctive chile flavor. Start with half the amount if your flakes are especially hot.
- Get the skin dry before saucing. Patting the thighs dry helps them brown. The marinade adds moisture, so keep most of it on the flesh and under the skin rather than leaving a thick puddle over the skin. A little browning is still possible even if the skin is not perfectly crisp.
- Give the vegetables room. Crowding makes potatoes steam instead of roast. Use a large sheet pan, or split the potatoes and onion between two pans if needed. Keep the chicken on one pan if possible so you can collect its flavorful drippings with the vegetables.
- Keep raw-chicken tools separate. Use a clean spoon for the reserved sauce and wash hands, dishes, and the work surface after handling raw poultry. Never brush cooked chicken with sauce that touched raw chicken unless that sauce has been brought to a boil.
Serving Suggestions
Serve the chicken straight from the roasting pan with the potatoes and onion, making sure each plate gets some of the savory pan juices. A simple green salad dressed with olive oil and vinegar adds a crisp, fresh contrast to the warm chile and garlic. Steamed green beans, sautéed greens, or roasted peppers also fit well without competing with the piri-piri sauce.
If you want a heartier table, add crusty bread to catch the juices or serve a modest bowl of plain rice alongside the pan. Put lemon wedges and the reserved sauce within reach so everyone can season their own portion. The sauce is bright and spicy, so a cooling side such as sliced cucumber or a spoonful of plain yogurt can be useful for diners who prefer less heat.
Variations
Make it milder or hotter: For a gentle version, leave out the cayenne and use just a pinch of crushed red pepper. For more heat, add another small dried bird’s-eye chile or a little extra cayenne to the blender. Change the sauce gradually; it is easier to add heat at the table than to soften a sauce that is too fiery.
Use boneless thighs: Boneless, skinless thighs work, though they cook faster and will not develop crisp skin. Add them after the potatoes have roasted for 15 minutes, then begin checking after about 20 minutes. Use a thermometer to confirm 165°F (74°C) in the thickest piece rather than relying only on the clock.
Try a different side in the pan: Carrots cut into short, thin pieces can roast with the potatoes and onion. Avoid adding quick-cooking vegetables at the beginning, as they may become too soft during the full roasting time. For a more traditional chile flavor, use dried piri-piri chiles when available; the crushed-pepper substitution is convenient but less floral and earthy.
Make it dairy-free: The recipe is dairy-free as written. If serving a cooling yogurt sauce on the side, offer it separately so the chicken itself remains suitable for guests avoiding dairy. For a brighter sauce, add another teaspoon of lemon juice after blending and taste before adding more salt.
Storage and Reheating
Refrigerate leftover chicken and vegetables within 2 hours of cooking, in shallow airtight containers. They keep for 3 to 4 days in the refrigerator. Store any clean reserved sauce separately; discard sauce that has been contaminated by raw chicken or left out too long. For longer storage, freeze cooled portions in a freezer-safe container for up to 2 months for best quality, then thaw overnight in the refrigerator.
For reheating, place chicken and potatoes in a covered oven-safe dish with a spoonful of water or broth to reduce drying. Heat at 325°F (165°C) until the center of the thickest piece reaches 165°F (74°C), checking with a food thermometer. A microwave also works: cover loosely, heat in short intervals, and turn the pieces so they warm evenly to 165°F (74°C). The skin will soften during storage; uncovering the dish for the last few minutes in the oven can help it regain some texture.
Frequently Asked Questions
What does piri-piri mean in this recipe?
Piri-piri refers to the small, hot African bird’s-eye chile used to give the sauce its heat. The name is used in different ways, and Portuguese-style recipes vary in their chile, vinegar, and herb choices. This version keeps the defining garlicky, acidic, chile-forward character while allowing a convenient crushed-red-pepper substitute.
Can I marinate the chicken overnight?
Yes. Cover it and refrigerate for up to 12 hours. The lemon juice and vinegar make the marinade acidic, so very long marinating can affect the texture of the surface. Keep the 2 tbsp (30 ml) serving sauce separate before it touches the raw chicken, as directed.
Can I use chicken breasts instead of thighs?
You can, but breasts are leaner and may dry out sooner. Choose bone-in breasts of similar size if roasting them with the potatoes, and begin checking their internal temperature early. Remove each piece as soon as it reaches the poultry safe minimum of 165°F (74°C); do not wait for every piece to finish if sizes differ.
How do I know the potatoes are done?
Test the largest piece with a small knife or fork. It should slide in without a hard center, and the edges should be lightly browned. If the chicken is already at 165°F (74°C), transfer it to a clean plate to rest while the potatoes continue roasting, then serve both together.
Can I prepare the sauce ahead?
Yes. Blend it up to 2 days ahead and keep it covered in the refrigerator. Stir or shake it before using because the oil and other ingredients may separate. Set aside the clean serving portion before coating the raw chicken, and do not reuse marinade from the chicken dish as a finishing sauce.
