The texture is wonderfully complex, a delightful combination of smooth and slightly chunky. People adore it because it's incredibly versatile, easy to make, and adds a touch of Mediterranean magic to any dish. Whether you're a seasoned chef or a kitchen novice, this recipe is guaranteed to impress. So, let's dive in and discover the secrets to making the perfect Romesco!

Ingredients:
- 1 large red bell pepper
- 4 ripe tomatoes (about 1.5 lbs), cored
- 1/2 cup blanched almonds
- 1/4 cup hazelnuts
- 2 slices of day-old bread, crusts removed
- 4 cloves garlic, unpeeled
- 1/4 cup extra virgin olive oil, plus more for drizzling
- 2 tablespoons red wine vinegar
- 1 teaspoon smoked paprika (pimentón de la Vera)
- 1/2 teaspoon cayenne pepper (optional, for heat)
- Salt to taste
- Fresh parsley, chopped (for garnish)
Roasting the Vegetables:
Okay, let's get started! The first step is roasting our veggies. This is where the magic happens, bringing out the sweetness and depth of flavor that makes Romesco so special. Don't skip this step it's crucial!
- Preheat your oven to 400°F (200°C). Make sure your oven is fully preheated before you put anything in. A consistent temperature is key for even roasting.
- Prepare the bell pepper and tomatoes. Wash the red bell pepper and tomatoes thoroughly. Place them directly on a baking sheet lined with parchment paper. The parchment paper makes cleanup a breeze!
- Roast the vegetables. Place the baking sheet in the preheated oven and roast for 30-40 minutes, or until the bell pepper skin is blackened and blistered, and the tomatoes are soft and slightly wrinkled. Keep an eye on them you want them nicely charred, but not burnt to a crisp.
- Cool the vegetables. Once roasted, remove the baking sheet from the oven. Place the roasted bell pepper in a bowl and cover it tightly with plastic wrap. This will help steam the pepper, making it easier to peel later. Let the tomatoes cool slightly on the baking sheet. Let both cool for about 15-20 minutes.
Preparing the Nuts and Bread:
While the vegetables are cooling, we can get the nuts and bread ready. These add texture and richness to the sauce, so don't skimp on the quality!
- Toast the nuts. In a dry skillet over medium heat, toast the almonds and hazelnuts for 5-7 minutes, or until they are lightly golden and fragrant. Be careful not to burn them! Stir them frequently to ensure even toasting. Alternatively, you can toast them in the oven at 350°F (175°C) for about 8-10 minutes.
- Remove the skins from the hazelnuts. Once the hazelnuts are cool enough to handle, rub them vigorously in a clean kitchen towel to remove as much of the skins as possible. Don't worry if you can't get all the skins off a little bit is fine.
- Toast the bread. Drizzle the bread slices with a little olive oil and toast them in the same skillet over medium heat for 2-3 minutes per side, or until they are golden brown and crispy. You can also toast them in a toaster oven. The bread should be nice and crunchy.
Peeling and Preparing the Roasted Vegetables:
Now it's time to tackle those roasted vegetables. This part can be a little messy, but it's worth it for the amazing flavor!
- Peel the bell pepper. Remove the bell pepper from the bowl and peel off the blackened skin. It should come off easily thanks to the steaming process. Discard the skin.
- Remove the seeds and stem from the bell pepper. Cut the bell pepper in half and remove the seeds and stem.
- Peel the garlic. Wrap the unpeeled garlic cloves in aluminum foil and bake them in the oven at 400°F (200°C) for about 20 minutes, or until they are soft and fragrant. Once cooled, squeeze the roasted garlic from their skins.
- Peel and seed the tomatoes. Peel the skin off the cooled tomatoes. You can use a paring knife to help you. Cut the tomatoes in half and remove the seeds.
Making the Romesco Sauce:
Alright, we're in the home stretch! Now we're going to combine all our prepared ingredients into a beautiful, flavorful Romesco sauce. Get your food processor ready!
- Combine the ingredients in a food processor. In a food processor, combine the roasted bell pepper, roasted tomatoes, toasted almonds, toasted hazelnuts, toasted bread, roasted garlic, red wine vinegar, smoked paprika, cayenne pepper (if using), and 1/4 cup of extra virgin olive oil.
- Process until smooth. Process the mixture until it is smooth and creamy. You may need to scrape down the sides of the food processor a few times to ensure everything is evenly incorporated.
- Adjust the consistency. If the sauce is too thick, add a little water or more olive oil, one tablespoon at a time, until it reaches your desired consistency. I like mine to be thick but still pourable.
- Season to taste. Season the Romesco sauce with salt to taste. Remember, you can always add more salt, but you can't take it away!
- Pulse briefly. Pulse the food processor a few more times to incorporate the salt.
