Each family had its own twist, but the heart of the recipe stayed true: simple ingredients, big flavor. From a humble fishing village to kitchens around the world, Romesco’s rich heritage proves that timeless recipes never go out of style.

Your Questions About Romesco Sauce, Answered

  1. Is Romesco sauce spicy?  Not usually! Traditional Romesco has a deep, smoky flavor but isn’t spicy. If you like a little kick, you can easily add some cayenne pepper or chili flakes to turn up the heat.
  2. Can you make the Romesco sauce thinner? Absolutely. Just blend in a tablespoon of water at a time until you reach the texture you love. Tip: Romesco thickens in the fridge, so don’t be afraid to loosen it up a bit before serving.
  3. Can I make Romesco sauce gluten-free? Yes! Just skip the bread and boost the almonds to keep that creamy texture. It still tastes amazing and works great as a gluten-free dip or sauce.
How to Make Smoky Spanish Romesco Sauce

Step-by-Step Instructions

2.

Roast for Richness – Get That Smoky Base!

Preheat your oven and roast the tomatoes, red bell peppers, and garlic for about 40 minutes, or until their skins are charred and blistered. Be sure to turn them halfway through for even roasting. Once done, remove from the oven and let them cool — this makes peeling easier and keeps those rich, roasted flavors intact.

Peel for a Smooth, Silky Sauce

nce the roasted veggies have cooled, gently peel the skins off the tomatoes and red peppers — they should slide right off! Removing the skins gives your Romesco sauce a smooth, velvety texture without any bitterness.

4.

Blend It All Together

5.

Adjust, Taste & Perfect

Blend until your Romesco sauce is smooth and creamy. If it feels too thick, just add a splash of water and blend again until you reach your desired consistency.

Now taste it — this is your moment to make it yours! Adjust the seasoning with a pinch more salt, vinegar, or spices until the flavor sings.

6.
