Salsa de Cacahuate (Mexican Peanut Salsa)

Salsa de Cacahuate is a lesser-known Mexican salsa that deserves more attention. This peanut-based sauce combines the richness of roasted peanuts with the heat of chiles de árbol and the depth of roasted garlic. While not as common as tomato-based salsas, it’s incredible on tacos, grilled meats, or as a dip.

Ingredients

  • 1 cup raw peanuts (unsalted)
  • 6-8 chiles de árbol (adjust to taste)
  • 4 cloves garlic, unpeeled
  • 2 roma tomatoes
  • 1/2 white onion
  • 2 tablespoons vegetable oil
  • 1 cup water (or more for desired consistency)
  • 1 teaspoon salt (or to taste)
  • 1/2 teaspoon Mexican oregano (optional)
  • 1 tablespoon apple cider vinegar

Instructions

  1. In a dry skillet over medium heat, toast the peanuts until golden brown and fragrant, about 5-7 minutes. Stir constantly to prevent burning. Set aside.

  2. In the same skillet, toast the chiles de árbol until they darken slightly and become fragrant, about 1-2 minutes. Remove stems and set aside.

  3. Toast the unpeeled garlic cloves until spotty brown and softened, about 8-10 minutes. Peel once cool.

  4. Char the tomatoes and onion in the same skillet until they have dark spots and are softened.

  5. In a blender, combine:

    • Toasted peanuts
    • Toasted chiles
    • Peeled roasted garlic
    • Charred tomatoes and onion
    • Mexican oregano (if using)
    • Salt
    • Apple cider vinegar
    • 1/2 cup of water

  6. Blend until smooth, adding more water as needed to reach desired consistency.

  7. Heat oil in a saucepan over medium heat. Carefully pour in the blended salsa (it will sputter).

  8. Simmer for 5-10 minutes, stirring occasionally, until the salsa thickens slightly and the flavors meld.

  9. Taste and adjust seasoning with salt and vinegar if needed.

The salsa will keep in an airtight container in the refrigerator for up to a week. It might thicken when chilled - just thin with a little warm water if needed.

Serving Suggestions

  • Drizzle over tacos (especially good with grilled meat or fish)
  • Use as a dipping sauce for quesadillas
  • Spoon over grilled chicken or shrimp
  • Toss with roasted vegetables
  • Use as a base for a spicy peanut marinade

The beauty of this salsa is its versatility - while it’s traditionally Mexican, the peanut base means it can bridge different cuisines. Try it anywhere you might use a spicy peanut sauce.
