Easy Piri Piri Sauce - Homemade Nando's-Style Recipe

If you've ever stood in the Nando's queue wondering "could I just MAKE this at home?" the answer is YES, and it's easier than you think. This homemade piri piri sauce is smoky, garlicky, a little bit spicy, and SO much more flavourful than anything from a bottle. The secret? Roasting the onion and peppers first (hello, air fryer!) to get that gorgeous caramelised depth before everything gets blended into silky, saucy perfection.

I always have a jar of this sitting in my fridge. It's one of those GAME-CHANGER condiments that makes everything taste better, whether you're marinating chicken, stirring it through pasta, drizzling it over roasted veggies, or using it as a dipping sauce. Once you make it, you'll wonder how you ever lived without it.

Recipe Details:

• Prep Time: 10 minutes
• Cook Time: 30 minutes (including roasting)
• Total Time: 40 minutes
• Makes: 1 jar (approx. 300ml)
• Difficulty: Easy
• Special Equipment: Air fryer or oven, blender or food processor, small saucepan

The real magic here is in the roasting. Getting some good colour on the onion and peppers first adds a depth of flavour that you simply can't get from raw vegetables, it brings out their natural sweetness and gives the finished sauce that smoky, almost Nando's-esque quality. The dried chilies get rehydrated in boiling water before blending, and here's a little chef tip: DON'T throw away that soaking water. Adding it to the blender gives you an extra hit of chili flavour without any of the waste. After blending, a quick simmer on the stove brings everything together and mellows out any harsh raw garlic edge.

Why You'll Love This Recipe

• Better than the bottle: Fresher, more vibrant, and you control the heat level
• Ridiculously versatile: Marinades, dressings, pasta sauces, dipping sauces, you name it

• Keeps for weeks: Make a batch and thank yourself every day that week
• Easily adjustable heat: Dial it up or down depending on how brave you're feeling

Ingredients

For the Sauce:

• 1 white onion
• 2 red peppers
• 4 dried red chilies, rehydrated in boiling water (add more if you like it spicier!)
• 5 garlic cloves
• Zest and juice of 1 lemon
• ½ tablespoon smoked paprika (or regular paprika)
• Small handful of fresh oregano (or 1 tsp dried)
• 100ml apple cider vinegar (or red/white wine vinegar)
• 25ml olive oil (a good glug), plus extra for roasting
• Salt, to taste

Instructions

1. Roast the Vegetables: Dice the onion and red peppers into roughly even pieces. Spread them out in your air fryer basket, season well with salt, and drizzle with olive oil. Roast at 200°C for 20 minutes, shaking halfway through to get an even colour. You want them soft, slightly caramelised, and starting to catch at the edges, that colour equals flavour. Alternatively, roast on a tray in your oven at 200°C fan (220°C / 425°F / Gas Mark 7) for 25–30 minutes.

2. Rehydrate the Chilies: While the veg is roasting, place your dried chilies in a small bowl and cover with boiling water. Leave them to soak for at least 10 minutes until softened. Keep the soaking water, you'll be using it in the blender.

3. Blend the Sauce: Add the roasted onion and peppers to a blender or food processor along with the rehydrated chilies and their soaking water, lemon juice and zest, garlic cloves, smoked paprika, oregano, vinegar, and olive oil. Blend until completely smooth. Taste and adjust, does it need more lemon? More salt? More chili? Now's the time.

4. Simmer: Pour the blended sauce into a small saucepan and simmer over low heat for 10–15 minutes, stirring occasionally. This step brings everything together and rounds out any sharp edges. Once off the heat, season with salt to taste.

5. Store: Pour into a clean jar and leave to cool completely before sealing. Store in the fridge.

Chef's Tips

Shake the jar before using: The sauce can separate slightly in the fridge, which is totally normal for a homemade, preservative-free sauce. Just give it a good shake.

Char = flavour: Don't be afraid of a bit of blackening on your roasted veg. That slight char is exactly what makes this sauce taste complex and smoky rather than flat.

Blend while warm: Blending the roasted veg while it's still warm (or just cooled slightly) gives you a smoother result than blending cold.

Taste your chilies before adding them: Dried chilies can vary a lot in heat. Better to start with 4 and add more than blow the roof off your sauce!

Substitutions & Variations

• Smoked paprika: Regular paprika or a pinch of cayenne for extra heat
• Apple cider vinegar: Red or white wine vinegar
• Fresh oregano: 1 tsp dried oregano
• Dried red chilies: 1–2 fresh red chilies or ½ tsp chili flakes (adjust to taste)
• White onion: Brown onion or 2 large shallots

Storage

Fridge: Store in a sealed jar for up to 3–4 weeks. The vinegar acts as a natural preservative, so it keeps really well.

Freezer: Pour into ice cube trays and freeze for up to 3 months. Pop out a cube whenever you need a quick hit of flavour, brilliant for weeknight marinades.

Frequently Asked Questions

Q: Can I make this in a regular oven instead of an air fryer? A: Absolutely! Roast the diced onion and peppers on a lined baking tray at 200°C fan (220°C / 425°F / Gas Mark 7) for 25–30 minutes, tossing halfway. You want good colour on them, don't rush this step.

Q: How spicy is this? A: With 4 dried chilies it has a noticeable kick, similar to Nando's medium/hot. For a milder sauce, start with 2 chilies. For something properly fiery, go up to 6–8.

Q: Can I use fresh chilies instead of dried? A: Yes! Use 1–2 fresh red chilies (seeds in for heat, seeds out for milder). Skip the rehydrating step and just toss them straight in the blender.

Q: Why do I need to simmer it after blending? A: The simmering step mellows the raw garlic, brings the flavours together, and thickens the sauce slightly. It's a short step but makes a real difference to the finished flavour.

Q: Is this gluten-free? A: Yes, this recipe is naturally gluten-free. Just double-check your smoked paprika and vinegar labels to be safe.
