Romesco Sauce Uses

This sauce is best used as a condiment, much like you would use BBQ or even ketchup.  Because it has such big, bold flavors a little goes a long way. This Romesco sauce can also be used as a dip for your favorite keto friendly chips, crackers, or even with vegetables. It is an amazing accompaniment to roasted vegetables as well. You can also toss a few tablespoons of this sauce over zucchini noodles for a truly special keto pasta dish.

Romesco Sauce Ingredients

  • Roasted Red Peppers – To roast your own peppers, coat 3 large red peppers with olive oil and place them on an open fire and char each side for 1-2 minutes. Remove from flame and place them in a large brown paper bag or in a bowl covered with plastic wrap. This will help steam and cook them a bit longer. After 10 minutes, remove the peppers and peel away the skin. To make this recipe even quicker, buy a jar of roasted red peppers (in olive oil). This will save you precious time.
  • Tomato Paste – Instead of using regular tomatoes, tomato paste is far more concentrated with flavor and will not make your sauce watery.
  • Sun-Dried Tomatoes – These add a unique flavor to the sauce and make it even more rich.
  • Walnuts – Romesco sauce is traditionally made with almonds or hazelnuts. However, we have found that lightly toasted walnuts not only add a better flavor and texture, but it also adds healthier fats with more nutritional value.
  • Red Wine Vinegar – Adding vinegar or a touch of acidity helps balance flavors out and makes them pop.
  • Garlic – Flavors don’t get much more bold than raw garlic. To tame the flavor and pungency, you can roughly chop each clove and saute in olive oil for 1-2 minutes until fragrant.
  • Extra Virgin Olive Oil – This will help bring all of the flavors and textures together in your Romesco sauce.
