In Catalonia, cooks have a simple sauce that transforms everyday vegetables into something extraordinary, intensely smoky, nutty, and surprisingly easy to make with ingredients you likely have on hand.
The recipe, rooted in generations of farming tradition near Girona, prioritizes understanding how ingredients interact: toasted hazelnuts complementing blanched almonds, sherry vinegar balancing the deep earthiness of smoked paprika. It’s a philosophy of flavor, not just a recipe.
Chef Antoni, a farmer from Girona, embodies this tradition. He sees himself as a caretaker of flavor, preserving the agricultural heritage of Catalonia. Romesco sauce began as a resourceful solution, a way to use up leftover peppers, orchard nuts, and stale bread. The ingredients, red bell peppers, almonds, hazelnuts, bread, garlic, olive oil, sherry vinegar, and smoked paprika, are humble, but their combination yields a remarkable complexity.
The peppers are essential, blanched and peeled to concentrate their sweetness before being smoked. Pimentón de la Vera, the smoked paprika used in this recipe, is produced in the Extremadura region of Spain, where peppers are dried over oak fires. The result is a distinctive, lingering aroma that defines Romesco’s character. This isn’t just a sauce; it’s a taste of a place.
Unlike many nut-based sauces, Romesco retains a rustic texture. The almonds and hazelnuts are toasted, but left slightly chunky, providing a welcome contrast to the roasted peppers. Even the bread, soaked and squeezed dry, adds body without weighing it down. It’s a sauce you feel as much as taste.
The secret lies in that unexpected texture. It’s a direct result of Catalan cooks’ ingenuity, elevating simple ingredients through clever technique.
Traditionally, Romesco sauce is served with escalivada, a Catalan dish of roasted vegetables. It’s equally delicious with grilled fish or chicken, tossed with pasta, or spread on crusty bread. A drizzle of extra virgin olive oil is the perfect finishing touch, letting the sauce’s inherent flavors shine.
This recipe represents a traditional Catalan preparation, but it’s not a definitive guide. Variations exist, some including tomatoes or other ingredients. The health benefits depend entirely on the quality of the ingredients and your overall diet; it’s not a shortcut to better health.
Can I substitute other nuts? Walnuts or pine nuts can be used, but the flavor will shift. The texture will remain. I don’t have sherry vinegar? Red wine vinegar or balsamic vinegar are acceptable substitutes, though the flavor will be slightly different. Where can I find pimentón de la Vera? It’s increasingly available in specialty spice shops and online. Can I make this ahead of time? Romesco is best fresh, but it can be stored in the refrigerator for up to 2 days. My sauce is too smoky? Reduce the amount of smoked paprika next time.

How to make this spanish romesco sauce recipe
This Spanish spanish romesco sauce recipe takes about 20 minutes to prep and 25 minutes to cook.

Ingredients for smoky spanish romesco sauce
- 2 large red bell peppers
- 150g (¾ cup) blanched almonds
- 50g (¼ cup) toasted hazelnuts
- 2 slices rustic bread, crusts removed, soaked in water then squeezed dry
- 2 cloves garlic, minced
- 60ml (¼ cup) extra virgin olive oil, plus more for drizzling
- 30ml (2 tbsp) sherry vinegar
- 1 tsp smoked paprika (pimentón de la Vera)
- ½ tsp dried thyme
- Pinch of cayenne pepper (optional)
- Salt and freshly ground black pepper to taste
- A handful of fresh parsley, roughly chopped (for garnish)
Method, the Catalonia way
- Step 1: Roast the Peppers: Preheat oven to 200°C (400°F). Place red bell peppers directly on the oven rack and roast for 20-25 minutes, turning occasionally, until the skins are blackened and blistered. Transfer to a bowl, cover with plastic wrap, and let steam for 10 minutes. This makes peeling easier.
- Step 2: Peel and Seed: Once the peppers are cool enough to handle, peel off the blackened skin. Remove the stems and seeds.
- Step 3: Make the Romesco: In a food processor, combine the roasted peppers, blanched almonds, toasted hazelnuts, soaked bread, minced garlic, smoked paprika, thyme, and cayenne pepper (if using). Process until coarsely chopped.
- Step 4: Emulsify: With the food processor running, slowly drizzle in the olive oil until a smooth, but slightly rustic, paste forms. Add the sherry vinegar and pulse to combine. Season generously with salt and pepper.
- Step 5: Adjust and Serve: Taste and adjust seasonings as needed. Add more sherry vinegar for tanginess or smoked paprika for more smokiness. Drizzle with extra virgin olive oil and garnish with fresh parsley. Chef Antoni always says, ‘A good Romesco needs a little love and a generous hand with the olive oil!’
Tips from Chef Antoni, a local farmer from Girona
The traditional way in Catalonia is to keep it simple. Researchers behind the PREDIMED trial found that the spanish romesco sauce recipe pattern, anchored in olive oil and short ingredient lists, cuts cardiovascular risk roughly 30%. Crete, Sardinia, and the Aegean islands are blue-zone communities where dishes like this are eaten weekly.
