WHAT IS ROMESCO SAUCE?
Romesco is Catalonia’s iconic red sauce—born on Spain’s Mediterranean coast around Tarragona, where fishermen blended pantry staples into a robust accompaniment for grilled catch. At its heart are tomatoes and roasted red peppers, enriched with toasted almonds (sometimes hazelnuts), garlic, and bread for body. Sweet ñora peppers add that unmistakable depth—sun-dried, fruity, and smoky without the heat—balanced by sherry vinegar and a generous stream of extra-virgin olive oil. The result is a silky, brick-red purée that tastes simultaneously fresh and fire-kissed: nutty, savory, gently smoky, and bright.
Texture and flavor profile
- Texture: spoonable and creamy, with a subtle rustic grit from nuts and bread—meant to cling, not run.
- Flavor: tomato sweetness, pepper fruitiness, roasted nuttiness, and a lively vinegar snap; smoke and spice are supportive, not dominant.
How to use it (classic and creative pairings)
- Seafood essentials: grilled shrimp, charred octopus, seared scallops, roasted cod or halibut. Romesco was made for the sea.
- Vegetables: roasted cauliflower, asparagus, charred leeks, blistered green beans, grilled mushrooms, potatoes (patatas bravas-style).
- Meats and poultry: roast chicken, pork tenderloin, hanger steak, lamb chops—the acidity cuts richness beautifully.
- Tapas and boards: spread on crostini, serve with anchovies or oil-packed tuna, pair with Manchego and olives, or spoon alongside roasted leeks for a very Catalan bite.
- Everyday upgrades: drizzle over eggs, tuck into sandwiches and burgers, toss with warm farro or quinoa bowls, or use as a dressing base with extra EVOO.
Pro tips for best results
- Balance is key: adjust sherry vinegar and salt at the end until it “pops.”
- Let it rest 15–30 minutes; flavors knit and mellow.
- Aim for a thick-yogurt consistency so it clings to seafood and vegetables.
- If using jarred tomato sauce, choose one without added sugar; compensate with vinegar if needed.
Serving temperature and storage
- Serve at cool room temperature; cold mutes flavors.
- Keeps 4–5 days refrigerated; freezes well up to 1 month. Stir and re-season after thawing.
Romesco Sauce Recipe
Yield: About 2 cups | Time: 15–20 minutes
Ingredients
- 1/2 cup high-quality tomato sauce (jarred), unsweetened
- 2 large roasted red peppers, peeled and seeded (from a jar is fine), roughly chopped
- 1/2 cup toasted blanched almonds (or 1/3 cup almonds + 2 tbsp hazelnuts for complexity)
- 1 slice rustic bread (about 30–40g), torn; or 1/3 cup coarse breadcrumbs
- 2 garlic cloves, smashed
- 2 dried ñora peppers (or 1 tbsp ñora pulp), seeds removed and softened in hot water; reserve 2–3 tbsp soaking liquid
- Substitute: 1 tsp sweet paprika + 1/4 tsp smoked paprika if ñora unavailable
- 2–3 tbsp sherry vinegar, to taste
- 1/2 cup extra-virgin olive oil, plus more as needed
- 1/2 tsp smoked paprika (pimentón), optional if not using ñora
- Pinch cayenne or Aleppo pepper, optional for gentle heat
- 1/2–3/4 tsp kosher salt, plus more to taste
- Freshly ground black pepper, to taste
Method
-
Prep the flavor base
- Toast nuts in a dry skillet over medium heat until golden and fragrant, 3–5 minutes. Cool slightly.
- In the same skillet, add 1–2 tbsp EVOO and fry the bread pieces until crisp and golden. Cool.
-
Blend
- In a food processor, add almonds, fried bread, garlic, ñora pulp (or paprikas), and 1/2 tsp salt. Pulse to a coarse crumb.
- Add roasted red peppers and the jarred tomato sauce. Blend until mostly smooth but still textured.
-
Emulsify
- With the motor running, stream in 1/2 cup EVOO. Add 2 tbsp sherry vinegar and 1–2 tbsp ñora soaking liquid to loosen. Blend to a creamy, spoonable sauce (aim for a thick yogurt consistency). If too thick, add more soaking liquid or a splash of water; if too thin, pulse in more nuts or breadcrumbs.
-
Season
- Taste and adjust: more vinegar for brightness, salt for depth, paprika/cayenne for warmth, and black pepper to finish.
-
Rest (optional but recommended)
- Let sit 15 minutes (or chill up to 3 days). Flavors bloom as it rests. Bring to room temp before serving.
Serving ideas
- Spoon over grilled shrimp, seared scallops, roast chicken, or charred vegetables.
- Spread on toasted baguette or crostini.
- Drizzle on roasted leeks or serve alongside tuna/anchovies for a Catalan-style tapa.
- Toss with warm potatoes or spoon over eggs.
Quality notes for jarred sauce
- Choose a tomato sauce with minimal sugar and clean ingredients; taste first. If sweet, balance with an extra 1/2–1 tbsp sherry vinegar.
- If the sauce is very loose, hold back the ñora soaking liquid until you see the final texture.
Storage
- Refrigerate in an airtight container up to 5 days. Freeze up to 1 month. Stir and adjust seasoning after thawing.
Chef’s tip
- For a smokier profile, lightly char an extra slice of bread or add 1–2 oil-packed sun-dried tomatoes for umami depth.
