Piri piri chicken is one of the great fire-grilled dishes of the world - a Portuguese-African recipe built on the fierce, fruity heat of piri piri chillies blended with garlic, lemon, smoked paprika, and herbs, used as both a marinade and a basting sauce for chicken that's grilled until deeply charred and smoky. It's the dish that made Nando's famous across the UK, and the homemade version is genuinely superior in every way.

The piri piri chilli - also known as African bird's eye chilli - originates in sub-Saharan Africa and was adopted into Portuguese cooking during the colonial era, particularly in Mozambique and Angola. The result is a flavour profile that's entirely unique: hot, citrusy, garlicky, and smoky all at once, with a depth that goes far beyond a simple chilli sauce.

This recipe uses a homemade piri piri marinade built from bird's eye chillies, roasted red pepper, garlic, lemon, smoked paprika, and red wine vinegar - all available at UK supermarkets. Bone-in, skin-on chicken thighs give the best result on the BBQ or in the oven, and the marinade doubles as a basting sauce during cooking for maximum flavour. Serve with chips, a simple slaw, and garlic bread for the ultimate piri piri feast at home.

1 tsp Dried Oregano

Method

Place all the marinade ingredients into a food processor or blender and blitz to a smooth paste. Taste - it should be hot, smoky, and intensely flavoured. Add more chilli for heat or more lemon for brightness. Reserve 3–4 tbsp of the marinade in a separate bowl to use as a basting sauce during cooking - keep this separate from the raw chicken.

Tip: Roasting the red pepper yourself gives a deeper, smokier flavour — halve and deseed a pepper, roast at 200°C fan for 20–25 mins until charred, then peel. For speed, a jarred roasted red pepper works very well and is what most home cooks use.
Score the chicken thighs 2–3 times through the skin down to the bone with a sharp knife. Place in a large bowl or zip-lock bag and pour over the marinade (not the reserved basting portion). Massage thoroughly into every cut and crevice. Cover and refrigerate for at least 4 hours - overnight gives the best result.

Tip: Scoring the chicken allows the marinade to penetrate deep into the meat rather than just coating the surface. Don't skip this step - it's the difference between a marinade that flavours the skin and one that flavours the whole piece.
Remove the chicken from the fridge 30 mins before cooking to take the chill off.

To cook on the BBQ: Preheat the BBQ to medium-high. Cook the chicken skin-side down over indirect heat for 30–35 mins, turning occasionally, until cooked through. Move over direct heat for the final 5–8 mins, basting with the reserved marinade and turning frequently, until the skin is deeply charred and caramelised.
To cook in the oven: Preheat to 200°C fan / 220°C conventional / Gas Mark 7. Arrange the chicken skin-side up on a foil-lined roasting tin. Roast for 35–40 mins, basting with the reserved marinade halfway through, until the skin is deeply golden and charred at the edges and the internal temperature reaches 75°C. Finish under a hot grill for 3–4 mins if you want more char on the skin.
Rest for 5 mins before serving with chips, coleslaw, and lemon wedges.

Tip: The reserved basting sauce is key to building layers of flavour during cooking. Apply it generously in the final stages - it caramelises on the skin and creates the sticky, charred coating that makes piri piri chicken so good.

Air Fryer Method

Preheat the air fryer to 200°C for 3–5 mins.
Place the marinated chicken thighs skin-side up in the basket in a single layer. Cook in batches if needed.
Cook for 25–28 mins until the skin is deeply golden and charred at the edges and the internal temperature reaches 75°C. Brush with the reserved basting marinade halfway through cooking and again in the final 3–4 mins for a sticky, caramelised finish. No turning needed.

Tip: The air fryer produces excellent piri piri chicken - the intense circulating heat chars the skin beautifully and the basting marinade caramelises into a sticky, flavour-packed coating. Line the basket with foil for easier cleaning as the marinade is sticky and acidic.

Alternatives & Variations

Remove the skin before marinating - reduces fat and saturated fat significantly; score the flesh directly and massage the marinade in; the char won't be as dramatic but the flavour is excellent
Use skinless chicken breast instead of thighs - leaner, though reduce oven cooking time to 25–28 mins and check carefully to avoid drying out; chicken breast benefits from basting more frequently
Reduce the olive oil in the marinade to 1½ tbsp - the roasted pepper and lemon provide enough moisture to carry the marinade without the full amount of oil

FAQs

Around 1 hr 5 mins of active prep and cooking, plus at least 4 hours of marinating time - overnight is strongly recommended. The hands-on work is minimal; most of the time is the chicken marinating and then cooking through on the BBQ or in the oven.

Rated Easy. The marinade is made in a blender in minutes, and the cooking is straightforward grilling or oven roasting. The main technique is managing heat on the BBQ to avoid burning before the chicken is cooked through - indirect heat first, then direct for the final char.

With 3–4 bird's eye chillies the heat is medium-hot - around a 6–7 out of 10. For mild, use 1 chilli and remove the seeds. For medium, use 2 chillies with seeds removed. For genuinely hot, use 4–5 chillies seeds in. The roasted red pepper and lemon balance the heat and prevent it tasting one-dimensional.

Yes - freeze the raw chicken in the marinade in a zip-lock bag for up to 3 months. It continues marinating as it defrosts overnight in the fridge, which is ideal. Cooked piri piri chicken also freezes well - cool completely and freeze in an airtight container for up to 3 months. Reheat covered in foil at 180°C fan for 20–25 mins until piping hot.

Yes - the marinade keeps in an airtight jar in the fridge for up to 5 days, or can be frozen in portions for up to 3 months. Making a larger batch and freezing it in ice cube trays is a great way to always have piri piri marinade on hand.

Chips and coleslaw are the classic accompaniments - simple, satisfying, and perfect for mopping up the juices. Garlic bread, corn on the cob, and a simple green salad also work brilliantly. For a more substantial spread, serve alongside rice and chargrilled vegetables.

Yes - the air fryer is an excellent method for piri piri chicken, particularly when the BBQ isn't an option. Preheat to 200°C, place the marinated thighs skin-side up in a single layer, and cook for 25–28 mins, basting with the reserved marinade halfway through and again in the final few minutes. The skin chars and caramelises beautifully. Line the basket with foil for easier cleaning.
