Key Ingredients for Romesco Sauce
Traditional Ingredients
The beauty of Romesco sauce is in its simplicity. Here’s what you’ll typically need:
- Roasted red peppers – These bring sweetness and color to the sauce.
- Tomatoes – Adds depth and a touch of acidity.
- Garlic – A must-have for that pungent kick.
- Almonds or hazelnuts – These provide the signature nutty flavor.
- Extra virgin olive oil – For richness and smooth texture.
- Vinegar (usually sherry or red wine vinegar) – For a bright, tangy finish.
- Smoked paprika – Brings in the smoky, earthy undertones.
- Bread (toasted or stale) – Used to thicken the sauce.
Modern Substitutions
Can’t find some of these ingredients? No worries. Here are some handy swaps:
- Use jarred roasted peppers if you’re short on time.

Step-by-Step Romesco Sauce Recipe
Step 1: Gather Your Ingredients
Before you start blending and roasting, gather everything you need:
- 2 large red bell peppers (or one 12-ounce jar roasted red peppers)
- 2 medium tomatoes, halved
- 3 garlic cloves
- ½ cup raw almonds
- ¼ cup extra virgin olive oil
- 2 tablespoons red wine vinegar
- 1 slice day-old bread or ¼ cup breadcrumbs
- 1 teaspoon smoked paprika
- Salt and pepper to taste
This recipe makes about 1½ cups of sauce.
Step 2: Roast the Vegetables
Start by roasting the peppers and tomatoes. If you’re using fresh peppers, place them under a broiler or directly over a gas flame until the skins are blackened and blistered. Once roasted, put them in a bowl and cover with a plate to steam for 10 minutes—this helps loosen the skin. Peel off the charred skin and remove the seeds.
Do the same with the tomatoes—roast until soft and slightly charred. This caramelizes their sugars and adds a depth of flavor.
Toss the garlic cloves (skin on) onto the baking sheet too, just for about 10 minutes, until they’re golden and soft.
Step 3: Blend Everything Together
Now it’s time to bring it all together. Add the peeled peppers, tomatoes, and garlic (peeled) into a food processor or blender. Add the almonds, toasted bread, paprika, and vinegar. Blitz until you get a coarse paste.
Drizzle in the olive oil while blending to create a creamy emulsion. If the sauce is too thick, add a tablespoon of water or more olive oil until you reach your desired consistency.
Step 4: Adjust Seasoning and Texture
Taste your sauce—this part is essential. Adjust the salt, maybe add a pinch more paprika, or a splash more vinegar for tang. If you like a smoother sauce, keep blending; if you prefer it chunkier, pulse less. It’s all about your preference.
Tips for the Perfect Romesco Sauce
Getting Romesco sauce just right is all about technique and attention to detail. Even though it’s simple, a few tricks can take it from good to absolutely unforgettable.
1. Roast your veggies properly: Roasting the peppers and tomatoes until they’re slightly charred adds a deep, smoky flavor that raw or boiled vegetables just can’t provide. The caramelization that happens in the oven or over an open flame brings out natural sugars, creating complexity in the sauce.
2. Use good-quality olive oil: Since olive oil is a major component of Romesco, don’t skimp. A good extra virgin olive oil will give your sauce that rich, velvety finish and enhance the overall flavor.
3. Toast the nuts and bread: Toasting almonds and bread before blending adds a nutty aroma and gives the sauce a more intense flavor. Just be careful not to burn them—golden brown is what you’re aiming for.
4. Balance is key: Romesco should hit multiple notes: smoky, tangy, nutty, and slightly sweet. Tweak the vinegar, paprika, or salt to suit your taste. If it tastes flat, a splash of vinegar usually does the trick.
5. Let it rest: If you have the time, let your sauce sit for at least 30 minutes before serving. This allows the flavors to meld beautifully, making it even more delicious.
Serving Suggestions
Romesco sauce is the kind of condiment that plays well with almost anything. Here are some delicious ways to enjoy it:
1. With grilled meats and seafood: Try spooning it over grilled chicken, pork, or steak. It’s also fantastic with shrimp, scallops, or grilled fish, which makes sense given its seafood origins.
2. As a dip: Serve it with crusty bread, pita chips, or veggie sticks. It’s a crowd-pleaser at parties or tapas-style dinners.
3. On roasted vegetables: Toss some roasted cauliflower, carrots, or potatoes in Romesco for a vibrant, flavorful side dish.
4. In sandwiches or wraps: Use it like a spread in your favorite sandwiches—it adds a punch of flavor and a creamy texture that’s better than mayo.
5. Mixed into pasta or grain bowls: Stir a few spoonfuls into pasta, quinoa, or rice for an easy, flavorful meal. Add some roasted veggies and a protein, and you’ve got dinner.
Storing and Shelf Life
One of the great things about Romesco is that it keeps well, making it perfect for meal prep.
- Refrigeration: Store your Romesco in an airtight container in the fridge for up to 1 week. The olive oil helps preserve it, and the flavors continue to develop over time.
- Freezing: Yes, you can freeze Romesco! Pour it into freezer-safe jars or silicone ice cube trays. Once frozen, transfer to a freezer bag. It’ll last up to 3 months. Thaw in the fridge and stir well before using.
- Pro Tip: Place a thin layer of olive oil on top of the sauce before storing—it acts as a natural preservative and keeps the surface from drying out.
Common Mistakes to Avoid
Romesco is pretty forgiving, but here are a few common pitfalls to steer clear of:
1. Using raw bell peppers: You’ll miss out on that iconic smoky sweetness. Always roast them first!
2. Skipping the nuts or using raw ones: Nuts add texture and flavor. Always toast them lightly to release their oils and deepen their flavor.
3. Over-blending: Romesco isn’t supposed to be baby-food smooth. It should have a bit of texture from the nuts and bread. Pulse your blender instead of going full speed.
4. Making it too thin: If you add too much oil or water, the sauce can get runny. You want it thick enough to coat a spoon.
5. Not seasoning properly: Always taste and adjust at the end. The right amount of salt, vinegar, and paprika can make or break the flavor.

FAQs about Romesco Sauce Recipe
1. Is Romesco sauce supposed to be served hot or cold?
Great question! Romesco sauce is traditionally served at room temperature or slightly chilled. That said, it’s incredibly versatile. You can gently warm it for pasta or hot dishes, but most of the time it’s used cold or at room temp as a dipping sauce, spread, or condiment. Just make sure not to overheat it, as the oils can separate and affect the texture.
2. Can I make Romesco sauce without a food processor or blender?
Absolutely! It might take a little elbow grease, but you can make a more rustic version using a mortar and pestle. It’s actually closer to the original method used in Catalonia. The texture will be chunkier, but the flavor will still be incredible. Just make sure everything is finely chopped before mixing and pounding.
3. How long does homemade Romesco sauce last?
Stored properly in an airtight container in the fridge, homemade Romesco can last up to 7 days. You can extend its life by freezing it in small batches. Just thaw and stir before using.
4. What can I use instead of almonds in Romesco sauce?
If you have a nut allergy or simply want a different taste, you can use sunflower seeds or pumpkin seeds as a nut-free option. Walnuts, cashews, or hazelnuts are also great substitutions depending on your flavor preference.
5. Is Romesco sauce spicy?
Not by default. Traditional Romesco isn’t spicy, but it’s very flavorful thanks to the smoked paprika, garlic, and vinegar. If you want a kick, you can easily add in roasted chilies or a dash of cayenne to heat things up.

It’s also wonderfully customizable—play around with the nuts, level of heat, or even add fresh herbs for a new spin. And the best part? It’s super easy to make with just a few pantry staples and fresh ingredients.
