Do I have delicious recipe for you!
A few weeks ago, I was eating a bowl of zoodles topped with a rich, smokey sauce at one of my favorite restaurants. After a few bites, I immediately knew I had to recreate that dish at home.
The zoodles were good and all, but the star of that mouthwatering entree was the amazing Romesco Sauce. It was so flavorful that I think I could have eaten a bowl of that tasty sauce alone and been happy.
Lucky for you, I’m sharing my Romesco recipe. I’m sure you’re going to love it just as much as I do, and it can be used to top everything from vegetables to pasta!
Easy Romesco Sauce (Salsa Romesco)
Have you ever had Romesco Sauce before?
Romesco (or Salsa Romesco in Spanish) is a nut and red pepper sauce that originated in the port town of Tarragona, Catalonia (Spain). It was originally intended to be served with fish, but there are so many uses for this irresistible sauce … like these Zucchini Noodles with Romesco and Feta, my Mediterranean Quinoa Bowl, or these yummy Grilled Vegetables.
This addictive sauce has an unique smokey, garlicky flavor that’s unforgettable. It’s rich and thick, and the nuts give it a great texture.
Once you learn how to make this Romesco recipe, you are going to be hooked. It’s so tasty and simple to make, too!
Romesco Sauce Ingredients
Wondering exactly what Romesco Sauce is made of? Although this sauce is Spanish in origin, you can find the ingredients in almost any grocery store:
- Roasted Red Peppers
- Crushed Red Pepper Flakes (optional)
- Smoked Paprika
- Olive Oil
- Sherry Vinegar
Romesco typically uses bread as a thickener, but I left it out of my recipe. I’m not Spanish or claiming this sauce is 100% authentic (and every cook has their own version anyway) … but it is super delicious!
How to Make Romesco Sauce
The best thing about Romesco, apart from it’s amazing taste, is that it’s so easy to make.
You’ll start by roasting the tomatoes. Use a sharp knife to make in X in the top and bottom of the tomatoes, then roast them until their skin is wrinkled and slightly charred.
Once the tomatoes are cool enough to handle, remove their skin and core them. Then, blot the tomatoes dry with a paper towel … this will keep your sauce from getting too runny.
While the tomatoes are cooking, toast the almonds in a small pan. Make sure to watch them closely, so they don’t burn.
Start by mincing the garlic in the processor. (This recipe does have a very garlicky flavor, by the way. If you’d prefer a milder garlic taste, roast the unpeeled garlic cloves with the tomatoes.)
Next, add the almonds and crushed red pepper flakes. Process until minced.
Sweet red peppers are the star of this sauce. I kept things simple and used a jar of roasted red peppers, but you could roast your own peppers if you wish (you’ll need two).
Just like you did with the tomatoes, blot the peppers dry with a paper towel. Then, add them to the garlic mixture, along with the roasted tomatoes, smoked paprika, and salt to taste. Process until smooth.
With the motor running, add the olive oil and sherry vinegar to your pepper sauce, blending until your sauce is thickened. (If you can’t find sherry vinegar, feel free to substitute white wine vinegar instead. Do not use sherry wine.)
And that’s it, your delicious Romesco Sauce is ready to be enjoyed. Just try not to eat it all with a spoon … it’s a challenge, I’m telling you!
By the way, Romesco can be frozen if you have any leftovers (doubtful). Simply place it in a small airtight container or freezer bag before freezing.
How to Use Romesco Sauce
Romesco Sauce can be served cold or hot (warm it in a microwave or over low heat), and it has so many uses!
I’ll be sharing a few recipes using this delectable sauce soon. In the meantime, try these creative ideas for using this delicious roasted red pepper sauce:
- Serve as a dip for crudité, crackers, and bread.
- Use as a pasta sauce or serve over zucchini noodles (or another spiralized veggies).
- Spoon over (or use as a dipping sauce for) steamed, roasted, or grilled vegetables.
- Stir into soups, stews, or even gazpacho.
- Use it to top fish, chicken, or meat.
- Mix with salad greens (thin with more oil and/or vinegar first, if desired).
- Use as a dressing for grain and veggie bowls, like this Mediterranean Quinoa Bowl.
- Serve with fries instead of ketchup.
- Spread on a pizza in place of pizza sauce.

You could also make like the Spanish, and serve this tasty sauce as a Romesco dip for roasted spring onions!
Each spring, Catalans roast calçots, a type of spring onion, over an open fire until the outer layer is charred (these traditional barbeques are called calçotades). The charred outside layer is then removed before dipping the tender onions in Salsa Romesco … doesn’t that sounds delicious?
