Romesco Sauce

Romesco sauce is creamy, slightly smoky and sweet from the roasted red peppers and has some umami from parmigiano reggiano. It's so delicious and extremely versatile. You can toss it with pasta, use it as a dip with veggies or as a sauce with any protein. It is healthy-ish as we use only a little bit of olive oil and parmesan cheese otherwise it gets a nice punch of nutrition from the red peppers and walnuts.  This recipe makes about 1 cup of romesco sauce.

Romesco Sauce

If you have never had romesco sauce you are in for a treat.  It is creamy, slightly smoky and sweet from the roasted red peppers and has some umami from parmigiano reggiano. This sauce is perfect to make during summer when red peppers are in season. However, it is also perfect to make year round because jarred roasted red peppers are excellent. You can use it as a pasta sauce, dip or a sauce with any protein or veggie. It is fairly healthy using only a little bit of olive oil and parmesan cheese otherwise it gets a nice punch of nutrition from the red peppers and walnuts.  

What You'll Need

  • Roasted Red Peppers
    • Make your own:
      • Char on all sides until blackened. You can do this directly over an open flame or with your boiler in the oven. Once completely charred place in a container and cover with plastic wrap. Allow to cool for 10-15 min.
      • Remove the skin, stem and seeds from the peppers and slice into strips. 
    • Buy jarred roasted red peppers from the grocery store.
      • They are usually found in the aisle near the other jarred and canned vegetables.
      • They sell them whole or sliced and you can opt for either!
  • Walnuts 
    • Toast them until just golden brown. You can do this in a saute pan over medium heat or on a sheet pan in the oven at 375° until fragrant about 5-10 minutes turning halfway through. 
  • Parmigiano Reggiano – Or parmesan cheese 
  • Garlic 
  • Sun Dried Tomatoes – adds a touch of tomato for a depth of flavor
  • Sherry Vinegar – This is necessary to waken things up. Substitute apple cider vinegar if needed. 
  • Oil – Use olive oil or avocado oil
