Roasted Red Pepper Romesco
The Spanish sauce that quietly outperforms every other condiment in your fridge — fire-roasted red peppers, toasted almonds, charred garlic, and smoked paprika blended into a rich, nutty, slightly smoky sauce that works on grilled meat, roasted vegetables, fish, sandwiches, pasta, and eggs. Make a batch on Sunday and it’ll change every meal for the next two weeks.
Equipment
Ingredients
Romesco Base
- 3 piece large red bell peppers or one 12-oz jar roasted red peppers, drained
- 4 piece Roma tomatoes halved lengthwise
- 1 piece head of garlic top sliced off to expose cloves
- 1/2 cup Marcona almonds or blanched regular almonds
- 1/4 cup extra virgin olive oil plus more for drizzling
- 2 tbsp sherry vinegar or red wine vinegar
- 1 tbsp smoked paprika pimentón de la Vera if possible
- 1 tsp cayenne pepper adjust to taste
- 1 piece slice of crusty bread about 1 inch thick, stale is fine
- 1 tsp kosher salt plus more to taste
- 1/2 tsp freshly cracked black pepper
Instructions
- Preheat oven to 450°F. Place whole red bell peppers, halved Roma tomatoes cut-side up, and the head of garlic cut-side up on a sheet pan. Drizzle the tomatoes and garlic with olive oil and season with salt. Roast for 20-25 minutes until the peppers are blistered and blackened in spots and the tomatoes are collapsed and caramelized.
- Transfer the roasted peppers immediately to a bowl and cover tightly with plastic wrap or a plate. Let them steam for 10 minutes — the trapped steam loosens the skins so they peel off effortlessly. Peel, stem, and seed the peppers. Do not rinse them under water — you will wash away all the roasted flavor.
- While peppers steam, toast the almonds in a dry skillet over medium heat for 3-4 minutes, tossing frequently, until golden and fragrant. Transfer to a plate to cool. In the same skillet, toast the slice of bread on both sides until deeply golden and crunchy, about 2 minutes per side. Tear into rough pieces.
- Squeeze the roasted garlic cloves out of their skins — they should be soft, sweet, and spreadable. Discard the papery shells.
- Add the toasted almonds and torn bread to a food processor. Pulse 8-10 times until you have a coarse crumb — this is the body of the sauce and what gives romesco its signature nutty texture.
- Add the roasted peppers, roasted tomatoes, squeezed garlic, smoked paprika, cayenne, sherry vinegar, salt, and black pepper. Pulse 10-15 times until combined but still slightly chunky. With the processor running, drizzle in the olive oil in a slow stream until the sauce comes together into a thick, spoonable consistency.
- Taste and adjust: more vinegar for brightness, more cayenne for heat, more salt to amplify everything. Romesco should taste roasty, nutty, slightly smoky, and just bright enough from the vinegar to keep you reaching for another spoonful.
- Transfer to a clean glass jar. Drizzle a thin layer of olive oil over the surface to seal — this prevents oxidation and keeps the color vibrant. Store in the refrigerator for up to 2 weeks. Bring to room temperature before serving for best flavor and texture.
Notes
Romesco is the most underrated sauce in existence. It originated in Tarragona, Spain, where fishermen made it to serve with seafood, but it works on literally everything. Once you have a jar in your fridge, you will find yourself putting it on things that don’t even need sauce.
Where to use it: Grilled steak, chicken, lamb, or pork chops. Seared or grilled fish, especially salmon and halibut. Roasted cauliflower, broccolini, or sweet potatoes. Spread on sandwiches and burgers instead of mayo. Tossed with warm pasta and a splash of pasta water. Dolloped on fried or scrambled eggs. Served as a dip with crusty bread, crudités, or grilled flatbread. Swirled into soup as a garnish. Spooned over a grain bowl.
The bread is not optional: A piece of toasted bread blended into the sauce is traditional and gives romesco its unique thick, creamy body without dairy. Stale bread works even better than fresh.
Marcona almonds vs. regular: Marconas are rounder, fattier, and sweeter than California almonds. They are the traditional choice and make a noticeable difference. Find them at Trader Joe’s, Whole Foods, or any Spanish grocery. Regular blanched almonds work in a pinch.
Smoked paprika is the soul: Regular paprika will not give you the same depth. Pimentón de la Vera from Spain is the gold standard — it’s actually smoked over oak and the difference is dramatic.
Shortcut version: Use a 12-oz jar of roasted red peppers instead of roasting your own. Drain and pat dry. Skip step 1 and 2 entirely. Still excellent.
