Romesco sauce is a classic Spanish condiment originating from Catalonia. It’s known for its rich and smoky flavor. Made primarily from roasted red peppers, almonds, garlic, and olive oil, it has a creamy texture and a slightly nutty taste. This versatile sauce is famous for its ability to enhance various dishes, from grilled meats and vegetables to pasta and sandwiches.
Romesco sauce is one of those recipes I always come back to — simple, bold, and full of flavor.
After years of cooking and traveling, I’ve tasted plenty of great sauces, but few are as versatile (and as easy) as Romesco.
I make mine with roasted red peppers, almonds, garlic, and olive oil — classic ingredients that don’t need anything fancy to taste amazing.
It’s the kind of sauce that just works, whether I’m serving grilled chicken, seafood, vegetables, or even just using it as a spread in sandwiches.
Over time, it’s become a regular in my kitchen. Quick to make, packed with flavor, and always a little more special than your everyday dips and sauces.
If you’ve never made it at home, trust me — once you do, you’ll wonder why it’s not already in your fridge.

Ingredients and substitutes
- Roasted Red Peppers: If you can’t find roasted red peppers, you can roast your bell peppers. Alternatively, you can use jarred roasted red peppers.
- Almonds: Almonds are traditional, but you can use other nuts, such as hazelnuts, walnuts, or sunflower seeds, for a nut-free version.
- Garlic: Fresh garlic is best, but you can use garlic powder if you don’t have fresh garlic on hand.
- Parsley: Fresh parsley adds brightness, but you can use other fresh herbs like cilantro, basil, or oregano.
- Red Wine Vinegar: You can also use sherry vinegar or balsamic vinegar as substitutes for red wine vinegar.
- Smoked Paprika: If you don’t have smoked paprika, you can also use regular paprika or a pinch of chipotle powder for a smoky flavor.
- Cayenne Pepper: Cayenne pepper adds heat, but you can also use other hot sauces or spices like red pepper flakes or chili powder.
- Salt and Pepper: To taste.
- Extra-virgin Olive Oil: Use a high-quality olive oil for the best flavor.
Step-by-step: Homemade romesco sauce
- Preheat the oven: Preheat your oven to 400°F / 200°C / Gas mark 6.
- Prep the veggies: Wash the red peppers and pat them dry. Cut the peppers in half and remove the seeds and membranes. Cut the bottom of the garlic bulb to expose the cloves. Place the garlic and pepper on a baking sheet lined with parchment paper or aluminum foil.
- Roast the veggies: Place the baking sheet in the oven and roast until the skin on the peppers is charred and blistered, about 20-25 minutes. Halfway through cooking, cover the garlic to prevent burning.
- Steam the peppers: Remove the baking sheet from the oven and immediately transfer the roasted peppers to a bowl. Cover the bowl with plastic wrap or a kitchen towel and let the peppers steam for 10 minutes. This will help loosen the skin.
- Peel the peppers: Once the peppers are cool enough to handle, peel off the charred skin. It should come off easily. Discard the skin. Squeeze the garlic out of the bulb.
- Blend: Combine the roasted red peppers and garlic, almonds, parsley, red wine vinegar, smoked paprika, cayenne pepper, salt, and pepper in a food processor. Blend until smooth. Slowly drizzle in the olive oil until the sauce is thick and creamy.
- Adjust: Taste and adjust seasoning, adding more salt, pepper, or vinegar as needed.
- Serve: Transfer the Romesco sauce to a bowl and serve with warm crostini, grilled vegetables, meats, or as a dip with crusty bread.
