Piri-piri chicken and slaw
About this recipe
Portuguese cooking is fundamentally a seafood and pork tradition, with bacalhau (salt cod) appearing in hundreds of forms, alongside Mediterranean staples — olive oil, garlic, tomato, sweet paprika — applied differently than in Spain.
As a chicken dish, Piri-piri chicken and slaw is forgiving enough to roast whole, braise in pieces, or quick-cook for a weeknight dinner — chicken accepts most techniques without losing its character.
The scaler above resizes every ingredient to the number of servings you actually want; Cook Mode walks you through the recipe one step at a time with hands-free timers.

Method
- STEP 1
- Whizz together all of the marinade ingredients in a small food processor. Rub the marinade onto the chicken and leave for 1 hour at room temperature.
- STEP 2
- Heat the oven to 190C/fan 170C/gas 5. Put the chicken in a roasting tray and cook for 1 hour 20 minutes. Rest under loose foil for 20 minutes. While the chicken is resting, mix together the slaw ingredients and season. Serve the chicken with slaw, fries and condiments.
Cooking notes
When scaling protein-led dishes, weigh the meat rather than counting pieces, and remember that the pan size limits how much you can sear at once.
For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.
When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
Scaling notes
Scaling Piri-piri chicken and slaw
Piri-piri chicken and slaw is written for around four servings as it stands on this page — scaling it up for a party or down for a meal-for-one is the small math problem most home cooks face every week. Here's how this particular dish responds to scaling, what changes linearly, and what doesn't.
Piri-piri chicken and slaw scales gracefully because chicken is forgiving — both the cooking method and the timing apply per piece rather than per total weight. The non-linear rule still applies to seasoning: at 2× volume use 1.5× the salt and spices, not full double, because flavour concentration intensifies as batch size grows.
The seasoning here is the most non-linear thing to scale. At 2× the recipe, use 1.5× the spices and salt; at 3×, use 2×; at 4×, use 2.5×. Doubling spices linearly is the most common reason a scaled-up batch tastes harsher than the original — flavour intensity compounds with volume.

Beyond the recipe
Substitutions & make-ahead — Piri-piri chicken and slaw
Two things home cooks ask about most when they're outside the recipe's exact assumptions: what swaps work for which ingredients, and how the dish behaves when you make it ahead. Both depend on what Piri-piri chicken and slaw is doing structurally — here's the practical version.
Substitution ideas
Yogurt
Plain yogurt → sour cream or labneh for thicker applications; or buttermilk for thinner sauces and marinades. Dairy-free yogurts (cashew, coconut, soy) all work for cooking applications — match fat content to the original.
For weight-based swaps and arbitrary quantities, the ingredient density converter and the cup-to-grams chart cover most pantry staples.
Make-ahead and storage
Piri-piri chicken and slaw tolerates make-ahead better than most home cooks expect. Cooked chicken keeps 3-4 days refrigerated and freezes well for up to 3 months. Reheat in a low oven (around 300 °F / 150 °C) covered, with a splash of broth — microwave reheating dries out lean breast meat especially. If the sauce is dairy-based (cream, yogurt), warm gently over low heat and stir as it comes back together; high heat breaks the emulsion.
