Ingredients List

• 3 medium red bell peppers (roasted and peeled)
• 2 medium ripe tomatoes (roasted)
• 1/2 cup toasted almonds or hazelnuts
• 2-3 garlic cloves (roasted or raw, depending on preference)
• 1 slice day-old bread, crust removed and toasted
• 1 tsp smoked paprika (preferably Spanish pimentón)
• 2 tbsp red wine vinegar
• 1/2 cup extra-virgin olive oil (plus more if needed)
• Salt to taste
• Freshly ground black pepper (optional)
• Pinch of cayenne or chili flakes (optional for a little heat)

Instructions

1. Roast the peppers and tomatoes: If you haven’t done so yet, roast your bell peppers under the broiler or on an open flame until the skin is blistered and blackened all over. Pop them in a sealed bowl covered with plastic wrap or a paper bag to steam for 10 minutes—this makes peeling a breeze. Roast the tomatoes until soft and slightly charred.
2. Toast your nuts and bread: In a dry skillet, gently toast the almonds or hazelnuts until golden and fragrant—watch them closely so they don’t burn. Toast the bread slice until crisp; it will add some lovely body to your sauce.
3. Blend the base: In a food processor or blender, combine peeled peppers, roasted tomatoes, toasted nuts, garlic, bread, smoked paprika, and red wine vinegar. Pulse until the mixture starts coming together but don’t stress if it’s a little chunky here and there—that’s character!
4. Emulsify: With the processor running, drizzle in olive oil slowly, allowing the sauce to thicken and become creamy. Taste and season generously with salt and a pinch of pepper or chili if you like a touch of heat.
5. Adjust consistency: If the sauce feels too thick, add a splash of water or more olive oil to reach your desired texture. Romesco should be thick enough to spread but still silky.
6. Serve or store: Transfer to a bowl and let it rest for at least 15 minutes to allow flavors to marry. Your kitchen will smell amazing right about now!

Serving Suggestions

Romesco is a remarkably versatile sauce. Serve it:

• Slathered over grilled fish or chicken
• As a dip for crunchy vegetables or toasted bread
• Alongside roasted potatoes or drizzled on grilled veggies like asparagus and zucchini
• Mixed into pasta or rice bowls for a flavor boost
• As a bold spread on sandwiches or burgers

Origin & History

Romesco traces its roots to Catalonia, a region in northeastern Spain known for its rich culinary traditions and vibrant Mediterranean flavors. Traditionally, this sauce was crafted by fishermen using simple pantry staples—roasted tomatoes and peppers to enhance grilled fish dishes. Over time, the blend gained popularity throughout Spain, evolving into a signature sauce that warms kitchens and hearts alike. While the exact recipe varies by village or family, its smoky, nutty character remains timeless.

Variations & Substitutions

If you want to shake things up (or need to accommodate dietary needs), here are some friendly tweaks:

• Nut-free version: Swap nuts for toasted sunflower seeds or omit them altogether and increase bread for texture.
• Vegan and gluten-free: Use gluten-free bread or substitute a small potato for thickness, and ensure your paprika is pure (some versions contain additives).
• Heat lovers: Add more cayenne or a splash of hot smoked paprika to turn up the fire.
• Smokier depth: Incorporate a bit of chipotle pepper or smoked salt if you want a bolder smoky flavor.
• Herbal twist: Fresh parsley or a touch of thyme brightens the sauce beautifully, especially on grilled meats.

Storage & Make-Ahead Tips

Romesco keeps beautifully! Store it in an airtight container in the fridge for up to 5 days. Give it a stir and add a drizzle of olive oil before serving if it thickens up. It also freezes well—pour into an ice cube tray to freeze in portions, then thaw in the fridge overnight as needed. Reheat gently at room temperature or warm slightly; avoid high heat to preserve the vibrant flavor.

FAQ

Q: Can I make romesco without roasted peppers?
A: While roasting enhances the deep sweetness and smoky notes, in a pinch you can use jarred roasted red peppers. Just drain them well and consider adding a little smoked paprika for that signature flavor.

Q: How long does romesco last in the fridge?
A: When stored airtight, it should stay fresh for about 5 days. The olive oil may solidify in cooler temps, so bring it to room temp and stir before serving.

Q: Is romesco gluten-free?
A: Traditional romesco includes toasted bread, but it’s easy to substitute gluten-free bread or small cooked potato chunks to keep it friendly for gluten-free diets.

All that said, romesco is the kind of sauce that grows on you—it’s smoky, nutty, and just a little bit unexpected in the best way. Give it a whirl; I promise your meals will thank you!
