Romesco Sauce is a flavorful sauce typically made with roasted red peppers, tomatoes, onions, garlic, almonds (or hazelnuts) that originates from the Catalonian region of Spain.

It tastes earthy, smoky, and slightly sweet with just a hint of heat – the perfect condiment for vegetables, meats and fish -complementing a wide range of meals.
The best part? It requires no hard-to-find ingredients (you already probably have everything on hand), is very simple and quick to make, and can be made ahead! Great for meal prepping for the busy week!
I’ve also included a quick 5-minute “cheater version” in the recipe notes made with jarred roasted peppers

What goes with Romesco Sauce?

Use Romesco Sauce like you would pesto- stir it into soups or stews, slather it into a panini, sandwich, or wrap, or toss it with pasta and sprinkle with shaved manchego, or simply serve it in a bowl like a dip, alongside crusty bread. I love its smokey flavor with:

In Spain, the traditional recipe also contains bread or bread crumbs for added texture (which I’ve left out this time) and Nora peppers which are difficult to find here in our area. I’ve kept this version intentional simple, easy and gluten-free- with more accessible ingredients.  Feel free to embellish!

Elevate Romesco Sauce!

  • To elevate the flavors, try grilling or smoking the peppers and onions which will give it a little charred smoky goodness.
  • Play with adding different peppers… or reconstituted dried chilies.

Description

Flavorful Romesco Sauce! You’ll find a million uses for this robust & flavorful Spanish condiment. Earthy, smoky and deep, it’s made with simple ingredients you probably already have on hand. EASY, Vegan & Gluten-free ( See 5-minute version in Notes)


Ingredients

Scale
  • 1 large bell pepper (or sub 1 cup roasted bell pepper)
  • ½ an onion
  • 2 garlic cloves, smashed
  • ¼ cup olive oil, divided
  • 3 tablespoons water
  • ½ cup toasted almonds or hazelnuts
  • 1 tablespoon tomato paste
  • 1 teaspoon cumin
  • 1 teaspoon smoked paprika
  • ½ teaspoon chili flakes
  • ½¾ teaspoon salt
  • 1 tablespoon sherry wine vinegar (or red wine vinegar)
  • ¼ cup chopped fresh Italian parsley

Instructions

Stovetop method (20 mins) 

Dice the red bell pepper and onion. Heat a skillet over medium heat and add 1 tablespoon olive oil, and saute onion and pepper until tender and fragrant, about 8 minutes. Add smashed garlic cloves and continue sauteing until onions and peppers start to caramelize.

Roasting Method (40 mins) 

Preheat oven to 425 F. Cut bell pepper in half, remove seeds and place open side down on a greased sheet pan. Add the onion, cutting ½ inch rings, add the garlic cloves whole, brush or spray with olive oil and roast 25-30 minutes, checking on garlic halfway through.  Remove garlic when tender and golden. Continue roasting pepper and onion another 10 minutes, or until all are tender and slightly charred.

Blend Romesco Sauce: 

Place the pepper-onion mixture a food processor with all the remaining ingredients (except the parsley). Pulse until combined. You can keep this quite coarse, with more texture, or blend until very smooth and creamy.

Add the chopped parsley and pulse a few times. Taste, adjust salt and heat.

To serve, place in bowl and drizzle with olive oil. Sprinkle with parsley and crushed nuts if you like.


Notes

Extra Heat: Feel free to add fresh chilies to the cooking/roasting onion-pepper mixture. Or rehydrated dried chilies to the food processor.

5-minute version: Substitute jarred or canned Roasted Peppers (one cup, drained) (In this case, simply brown the onions and garlic on the stovetop- or use 1-2 teaspoons of each, granulated.

Store in a sealed jar, covering the sauce with a layer of olive oil to prevent discoloring.

The vinegar extends its shelf life- and will keep for 10 days in the fridge.

  1. Sylvia!!!
    Another 5 star recipe…. so easy and sooooo delicious!!!
    I served this with Gluten-free spaghetti and it was a HUGE hit!
    Thank you very much for sharing!!!
    Judy

  2. My husband said this is the best thing I have ever made for him – and we’ve been together 12 years so there’s a lot of competition!

  3. I made this for Christmas with the t
    roasted potatoes and the moment I taste-tested it I knew it was just like my favorite Muhammara dip at a Mediterranean restaurant that I used to go to 10 years ago. I am *so* happy to find this version bc nothing I tried at restaurants or at home came close to this before. So, so good!!! Love all your recipes, thank you.

  4. Delicious and tasted very close to the romesco we fell in love with in Barcelona!

  5. Pretty darned good! I made it twice – the second time I also added pine nuts – yowsa! So good!

  6. Sylvia,

    This recipe is incredible I love it. As usual your recipes are amazing and so many of them are prepared regularly in my house making our everyday meals soooo good ! A huge thankyou!

    Annette.

  7. Love the romesco sauce! Tried the sweet potato balls, but had a hard time getting them formed–very gloopy. Next time, might try to refrigerate to firm up the mixture before coating with flour and searing. Other suggestions would be appreciated!

    Thanks for great ideas 🙂
