Romesco Sauce (Spanish Roasted Red Pepper & Almond Sauce)

By @saucesanddips | Classic Catalan Sauce for Grilled Meats, Seafood, and Veggies

Romesco is a smoky, nutty Spanish sauce from Catalonia made with roasted peppers, tomatoes, almonds, garlic, and sherry vinegar. Thickened with toasted bread and blended with olive oil, it’s a versatile condiment that’s incredible with grilled seafood, vegetables, chicken, and crusty bread.


Ingredients (Makes about 1½ cups)

  • 2 roasted red bell peppers, peeled and seeded (or 1 jar/12 oz roasted peppers, drained)
  • 2 plum tomatoes, halved and roasted (or ½ cup crushed tomatoes)
  • ½ cup toasted almonds (or ¼ cup almonds + ¼ cup hazelnuts)
  • 1 small slice day-old bread (about 25 g), toasted
  • 2–3 garlic cloves, peeled (roast with tomatoes for sweeter flavor)
  • 2 tablespoons sherry vinegar
  • 1 teaspoon smoked paprika
  • ¼ teaspoon cayenne pepper (optional, for heat)
  • ½ teaspoon fine sea salt, plus more to taste
  • ⅓–½ cup extra-virgin olive oil
  • Freshly ground black pepper, to taste

Instructions

1. Prep the Base
Roast tomatoes (and garlic if you like them mellow) at 425°F (220°C) until soft and lightly charred, 15–20 minutes. Let cool slightly.

2. Blend the Dry Ingredients
In a food processor, pulse toasted almonds (and hazelnuts if using) with the toasted bread until finely ground.

3. Add Vegetables & Seasoning
Add roasted peppers, tomatoes, garlic, sherry vinegar, smoked paprika, cayenne, and salt. Blend until mostly smooth with a bit of texture.

4. Stream in Oil
With the motor running, slowly stream in ⅓–½ cup olive oil until the sauce thickens and emulsifies. Season with black pepper and adjust salt/vinegar to taste.

5. Rest
Let sit 15–20 minutes before serving for flavors to marry.


Serving Ideas

  • Spoon over grilled shrimp, octopus, or white fish
  • Serve with charred asparagus, roasted cauliflower, or potatoes
  • Spread on sandwiches or use as a dip with crusty bread

Tips from @saucesanddips

  • For extra smokiness, char peppers and tomatoes over an open flame or grill
  • Bread adds body—use gluten-free bread to keep it GF
  • Keeps 5–7 days refrigerated; stir in a splash of olive oil before serving
