You need 40 minutes and a handful of roasted ingredients. No marinating, no precooking, just peppers, nuts, and a blender.
The oven does most of the work. Char the peppers until the skin blisters, toast the almonds until golden, then blend everything into a smoky, nutty sauce.
This is what we make when grilled chicken or steamed vegetables need more than salt and pepper. Works for weeknight meals or when you're hosting and want something that looks intentional.
Spanish romesco sauce starts with charred peppers and toasted almonds blended into a smoky, creamy dip. The trick is roasting peppers until the skin blisters and adding olive oil slowly so the sauce emulsifies instead of separating. Make this when you need a versatile sauce that works for dipping, drizzling, or spreading.

Quick Tip
Toast nuts and bread for best texture
Best For
Weeknight | Entertaining | Meal prep
What makes it work:
- Charring the peppers under the broiler develops smokiness without needing an open flame-8-10 minutes at high heat blisters the skin and softens the flesh
- Toasting almonds separately prevents burning and brings out the nutty oils that thicken the sauce and add texture
- Soaking bread in vinegar creates body without making the sauce gummy-squeeze out excess liquid before blending
- Adding olive oil slowly while the blender runs emulsifies the fats into a creamy, cohesive sauce instead of a separated, oily mess
- Blending in stages lets you control texture-nuts and bread first, then roasted vegetables, oil last
What You'll Need
Most people skip something simple like oil, but it balances the meal. Stock your pantry with roasted peppers, almonds, and sherry vinegar for a sauce that works all week.
- 2 large red bell peppers (roasted)
- 1 medium tomato (roasted or canned)
- ½ cup toasted almonds
- 1 slice crusty bread (soaked)
- 3 garlic cloves
- 2 tablespoons sherry vinegar
- 1 teaspoon smoked paprika
- ⅓ cup olive oil
- Salt to taste
- Optional: pinch of nutmeg
Ingredient Details
- Roasted red bell peppers
Char under broiler 8-10 minutes, turning every 3 minutes-skin should blister and blacken in spots for maximum smokiness - Toasted almonds
Toast in dry skillet over medium heat 5-7 minutes, stirring constantly-almonds should smell nutty and turn golden, not dark brown - Garlic cloves
Use fresh garlic only-crush and let sit 5 minutes before adding to mellow the bite and prevent harsh raw flavor - Sherry vinegar
Adds authentic Spanish acidity-start with 2 tablespoons, then adjust by the teaspoon until sauce tastes balanced - Crusty bread
Soak in water or vinegar 5 minutes, squeeze gently to remove excess liquid-too wet and the sauce gets gummy - Olive oil
Use good quality extra virgin-add slowly in a thin stream while blending to emulsify into a creamy texture - Smoked paprika
Essential for authentic smoky depth-don't skip it or substitute sweet paprika unless you want a milder flavor
Ingredient Swaps
A good this dip can make or break the plate. The oil works best when it hits the table at the same time as the main.
Four swaps that work:
- Almonds → hazelnuts or walnuts: Changes the nutty profile slightly-hazelnuts add earthiness, walnuts bring softer texture and milder flavor (budget)
- Bread → gluten-free bread or omit entirely: Affects thickness-sauce may be thinner without bread, so add extra nuts to compensate (gluten-free)
- Sherry vinegar → red wine vinegar: Less authentic Spanish flavor but maintains necessary acidity-use same amount, adjust to taste (budget)
- Fresh tomato → sun-dried tomatoes (rehydrated): Deeper, concentrated flavor and thicker sauce-soak in warm water 10 minutes before blending (budget)
Almonds
Works for: Traditional texture, creamy thickness, authentic nutty flavor
Skip if: Nut allergies or want to try hazelnuts for earthier taste
Hazelnuts
Works for: Deeper earthy flavor, still creamy, common in Catalan versions
Skip if: You prefer milder nutty taste or can't find toasted hazelnuts
Peanut Butter (natural, unsweetened)
Works for: Budget option, no toasting required, quick shortcut
Skip if: You want authentic flavor-peanut butter changes the profile significantly
Instructions
Roast the peppers until the skin blisters, then blend everything in stages. Lobster adds the contrast this plate needs, but timing matters-a flaky lobster side works when you need something fast.
Roast the peppers and tomato: Place bell peppers and tomato under broiler on a baking sheet. Broil 8-10 minutes, turning peppers every 3 minutes until skin blisters and blackens in spots. Tomato should soften and char slightly. Transfer peppers to a bowl, cover with plastic wrap, and let steam 5 minutes. Peel skins off peppers and tomato, remove seeds from peppers.
Toast the almonds and bread: Heat a dry skillet over medium heat. Add almonds and toast 5-7 minutes, stirring constantly, until golden and fragrant. Remove almonds. Tear bread into pieces, add to skillet, and toast 2-3 minutes until crisp and lightly browned. Soak toasted bread in water or vinegar 5 minutes, then squeeze gently to remove excess liquid.
Blend nuts and bread first: Add toasted almonds and soaked bread to blender or food processor. Pulse until coarsely ground with small nutty bits remaining-don't over-blend into powder.
Add roasted vegetables and seasonings: Add roasted peppers, tomato, crushed garlic, sherry vinegar, smoked paprika, and salt to blender. Blend until mixture is smooth but retains slight texture-about 30 seconds.
Emulsify with olive oil: With blender running on low speed, slowly drizzle olive oil in a thin stream through the top opening. Blend until sauce is creamy and emulsified, about 1 minute. Taste and adjust seasoning-add more vinegar for acidity, salt for balance, or paprika for smokiness. Sauce should be thick enough to coat a spoon but pourable.
What to Serve With It

| Side Dish | Prep | Why It Works | How to Serve |
|---|---|---|---|
| Grilled chicken | Easy | Smoky nutty sauce complements charred chicken without overwhelming | Drizzle over sliced chicken breast or thighs |
| Steamed green beans | Easy | Fresh crunch contrasts creamy richness, adds color to the plate | Toss warm beans with romesco or serve on the side for dipping |
| Roasted potatoes | Easy | Starchy base soaks up sauce, adds hearty substance to the meal | Serve potatoes in a bowl with romesco spooned over top |
| Crusty bread | Easy | Classic dipping option, soaks up every bit of sauce | Slice thick, toast lightly, serve in a basket alongside sauce |
| Grilled vegetables | Medium | Charred veg echoes smoky flavors in sauce, adds textural variety | Arrange grilled zucchini, eggplant, and peppers with romesco drizzled over |
Three ways to serve it:
- As a dip for charcuterie boards: Pair with cured meats, olives, and marinated artichokes-the nutty acidity cuts through rich, salty flavors
- Drizzled over grilled prawns: Seafood and romesco are a classic match-the smokiness complements briny sweetness without masking it
- Spread on sandwiches or wraps: Use as a condiment instead of mayo-adds depth and keeps sandwiches from tasting flat
Store and Reheat
Roast adds the contrast this plate needs, but timing matters. For a version that comes together quickly, tender homemade roast recipe keeps the prep simple without sacrificing flavor.
| Method | Time | Best For |
|---|---|---|
| 🍳 Stovetop | 3-5 min low heat | Gently warming small portions without breaking emulsion |
| 📦 Microwave | 1 min in short bursts | Quick single servings-stir between intervals to prevent separation |
| 🔥 Oven | 10 min at 300°F | Warming larger quantities in covered dish for serving |
For best results when storing:
- Cool completely before refrigerating: Hot sauce creates condensation in the container, which waters down flavor and speeds spoilage-let sit at room temperature 20-30 minutes
- Use shallow glass or plastic containers: Wide, shallow storage prevents oil separation better than tall, narrow jars-easier to stir before serving too
- Press plastic wrap directly on surface: Contact wrap prevents oxidation and keeps top layer from darkening or developing off flavors
- Freeze in small portions: Divide into ice cube trays or small containers so you can thaw only what you need-frozen romesco lasts 3 months
- Stir before serving cold or reheated sauce: Oil naturally separates during storage-whisk or blend briefly to re-emulsify before using
Frequently Asked Questions
Yes-romesco keeps in the fridge 3-4 days in an airtight container. Stir well before serving since the oil separates naturally during storage.
The skin should blister and blacken in spots, and the flesh should feel soft when pressed. If the skin hasn't charred after 10 minutes, move the pan closer to the broiler.
Yes-a food processor works fine and gives you more control over texture. Pulse in stages to keep some nutty bits instead of over-blending into a paste.
For thick sauce, thin with water, vinegar, or olive oil one tablespoon at a time while blending. For thin sauce, add toasted bread crumbs or more nuts and blend until thickened.
Fridge: 3-4 days in an airtight container. Freezer: up to 3 months in small portions-thaw overnight in the fridge and stir well before using.
