5-Minute Romesco Sauce
Romesco sauce is a smoky, nutty Spanish sauce made with jarred roasted red peppers, almonds, and a good splash of sherry vinegar. You can spoon it over grilled vegetables, serve it alongside crusty bread, or dollop it onto eggs for an instant upgrade.
It comes together in a blender in about five minutes. No roasting, no chopping, just a quick blitz until it is thick and brick-red.
Why This Romesco Sauce Works
The roasted peppers carry a gentle sweetness that balances the toasted almonds. A little smoked paprika nudges in warmth without any real heat.
It is thick enough to scoop as a dip, but a splash of water loosens it into a silky sauce that coats pasta or grilled fish beautifully. I keep a jar in the fridge and find myself reaching for it all week long.
Ingredients
- 1 12-ounce jar roasted red peppers, drained: use jarred peppers packed in water, not oil.
- 2 sun-dried tomatoes in oil, drained: optional, but they add a deep, savory backbone.
- ¼ cup slivered almonds: toast them in a dry pan first if you have an extra minute.
- 1 small garlic clove: start with one, you want it subtle.
- ½ teaspoon smoked paprika: look for one labeled “sweet” or “dulce.”
- 1 tablespoon sherry vinegar: red vinegar works in a pinch.
- ¼ cup extra-virgin olive oil: use a fruity one you would pour over a salad.
- ¼ teaspoon kosher salt: plus more to taste.
Variations / Substitutions
- Almonds: swap for toasted hazelnuts, walnuts, or even pine nuts for a softer roundness.
- Sherry vinegar: red vinegar gives a similar sharp lift, just a little brighter.
- Add heat: a pinch of cayenne or a few drops of hot sauce stirred in right before serving.
- No sun-dried tomatoes: leave them out. The sauce will be slightly sweeter and a shade lighter.
Tuna Tortilla Wrap is one of our favorite ways to use this sauce.
How to Make Romesco Sauce
Step 1: Blend the Base
Scrape the drained roasted red peppers, sun-dried tomatoes, almonds, garlic clove, smoked paprika, and sherry vinegar into a food processor or high-speed blender. Pulse a few times to break everything down, then run it continuously until the mixture looks coarse and brick-red, about 20 seconds. You want a little texture, not a completely smooth purée.
Step 2: Stream In the Olive Oil
With the motor running, slowly drizzle in the olive oil through the feed tube or top opening. Let it run until the sauce emulsifies and turns creamy and lighter in color, about 30 seconds. It should coat the back of a spoon but still feel nubby from the almonds.
Step 3: Swirl and Serve
Scrape the romesco into a small serving bowl. Taste and stir in the salt, then adjust with another small pinch if the flavors feel flat. If the sauce seems thicker than you like, add a teaspoon of cold water and stir. Use the back of a spoon to make a wide swirl across the top, drizzle with a little more olive oil, and sprinkle with smoked paprika or chopped toasted almonds. Serve right away or chill and bring back to room temperature later.
Tips for the Best Romesco
- Toast your nuts: A quick dry toast deepens the almond flavor and keeps the sauce from tasting raw. Spread slivered almonds in a small pan for about 3 minutes over medium heat, shaking once, until fragrant.
- Use a good olive oil: Since the oil is not cooked, its flavor really comes through. Reach for a fruity, peppery extra-virgin one you enjoy raw.
- Make it ahead: Romesco tastes even better after an hour in the fridge, once the garlic and paprika have time to meld. Just pull it out 20 minutes before serving so it loses the chill.
- Keep some texture: A blender can turn this into a smooth paste fast. Pulse in short bursts and scrape down the sides to keep some nubby bits from the almonds intact.
Scale the batch for a party:
| Ingredient | 1x | 2x | 3x |
|---|---|---|---|
| Roasted red peppers (12 oz jar) | 1 jar | 2 jars | 3 jars |
| Almonds | ¼ cup | ½ cup | ¾ cup |
| Olive oil | ¼ cup | ½ cup | ¾ cup |
| Sherry vinegar | 1 tbsp | 2 tbsp | 3 tbsp |
Make-Ahead and Storage
- Refrigerate: Transfer to a sealed container and keep in the fridge for up to 5 days. The flavors deepen overnight.
- Serve cold: Romesco thickens when chilled. Let it sit on the counter for 20 minutes and stir in a teaspoon of water to bring back a pourable consistency.
What to Serve with Romesco Sauce
Spoon it over roasted cauliflower or charred broccolini, where the smokiness doubles down. It also makes a great swipe under grilled chicken thighs or pan-seared white fish, adding brightness and fat. For a simple appetizer, set out a bowl with toasted pita or baguette slices and let everyone dunk.
Frequently Asked Questions
Can I use fresh tomatoes instead of sun-dried?
Yes. Roast a small tomato alongside the jarred peppers at 400°F for 15 minutes until it softens, then add it in. The sun-dried version skips that step for speed.
Is romesco sauce spicy?
No, the smoked paprika gives warmth without heat. If you want heat, stir in a pinch of cayenne or a few red pepper flakes.
Why does my sauce taste bitter?
Raw garlic can dominate, especially if the clove is large. Next time, start with half a clove or soak the garlic in the vinegar for a few minutes before blending to mellow it.
Can I freeze it?
You can, but the texture may separate when thawed. Freeze in small portions and re-blend with a teaspoon of water to bring it back together.
