Equipment

  • Blender or food processor
  • Skillet
  • Baking sheet

Ingredients
  

  • 1 red bell pepper
  • 6 plum tomatoes
  • 1 head garlic
  • 1 medium yellow onion
  • ½ cup extra virgin olive oil
  • ¼ cup almonds blanched
  • 2 slices baguette thin slices
  • 1 teaspoon salt
  • 1 Tablespoon sherry vinegar
  • 1 teaspoon Spanish sweet paprika pimentón
  • ¼ teaspoon ground red chili up to ½ teaspoon for spice, use ground ñora or ancho chili if possible

5-minute romesco sauce ingredient substitutes (see notes)

  • 16 ounce roasted red peppers jarred, drained
  • ¼ cup fire-roasted tomatoes drained
  • 2 cloves garlic peeled and minced (don't use a whole head if you're using raw garlic!)
  • keep remaining non-substituted ingredients the same!

Instructions
 

Roasting the Vegetables

  • Preheat the oven to 350˚F and lightly grease a rimmed baking sheet.
  • Cut an "x" into the top of each tomato. Place them on the baking sheet with the red bell pepper.
  • Remove the peel, then slice the head of garlic in half through the cloves. Place the halves cut side-up on the baking sheet.
  • Remove the outer layer of skin from the onion and cut it into wedges from the top. Don't cut all of the way through - keep it intact. Place cut side-up onto the baking sheet.
  • Brush the vegetables with olive oil and place in the oven. Roast until soft and beginning to char, 25-30 minutes.

Toasting Almonds and Bread

  • While the vegetables roast, place a small pan over medium-low heat with a drizzle of olive oil.
  • Add almonds once hot then cook, stirring often, until they are golden. Remove to a plate.
  • Add bread slices to the pan and toast until golden on each side. Remove from the heat and set aside.

Pureeing Romesco Sauce

  • Once roasted, add the bell pepper to a bowl and cover for 20 minutes. After 20 minutes, peel the skin from the bell pepper. Discard the stem and seeds.
  • Peel the skin and remove the seeds from the tomatoes.
  • Remove the skin from the onion and garlic.
  • Place all prepared vegetables in the blender or food processor. Add almonds, bread, salt, vinegar, paprika, ground red chili, and remaining olive oil.
  • Puree until smooth. Transfer to a bowl and taste for seasoning, adjusting as needed. Serve immediately, or refrigerate! Enjoy!

Notes

If you're short on time and want to make your romesco sauce in about 5 minutes, you can replace some of the ingredients to save time:
  1. Use fire-roasted canned tomatoes.
  2. Use jarred roasted red peppers.
  3. Don't roast the garlic or onions.
  4. Add everything to a blender except for the olive oil and blend until the sauce begins to smooth. Mix the olive oil in gradually as you finish blending. Taste and adjust seasoning as needed.
