Romesco Sauce

Naturally dairy free, this romesco sauce recipe yields a nutty red pepper sauce that’s a little smoky and full of flavor. It was intended to be eaten with fish, but this simple Spanish sauce can be used as a dip or served alongside any of your favorite proteins or vegetables.

Why you’ll love this romesco sauce

Similar to a pesto, this sauce is super easy to make. Just throw everything in a blender or food processor and you’re done.

It’s great served with fish (we just had it with sea bass and it was amazing), but we also love to serve it with roasted asparagus or use it as a dip for bacon wrapped dates. It’s even great on pasta – we even published a romesco pasta recipe on our other site – The Pasta Twins, but it’s not 100% dairy free.

You can blend until smooth or leave it chunky, depending on how you’re serving it. We like to leave it on the thicker side to use it as a dip, but as a sauce for fish, I think smooth is the way to go.

Ingredient notes:

  • Roasted red peppers – You can roast them yourself or buy some in a jar, just make sure you don’t accidentally buy pickled peppers. Look out for vinegar listed in the ingredients on the jar.
  • Almonds – I like to buy toasted sliced almonds from the store to make my life easier. You can easily toast them yourself, or swap the almonds for another nut of your choice. Just make sure you’re subbing equal parts. We’ve also swapped the almonds for peanuts to accommodate an tree nut allergy and it worked great!
  • Smoked paprika – you can substitute regular paprika for this ingredient, but you will definitely miss out on that beautiful smoky flavor that makes this romesco sauce so delicious. It’s totally up to you though. Use what you have.

Making changes to a recipe can result in recipe failure. Any substitutions listed below are simple changes that I believe will work in this recipe, but results are not guaranteed.

Melissa’s tips & tricks

  1. If you don’t have a food processor or blender, you could do it by hand with a mortar and pestle, but it will take a little more effort.
