Equipment

  • Food processor *A blender will also work, sauce will likely be smoother if you go this route.

Ingredients

  • 4 poblano peppers
  • 1 large clove of garlic *or two smaller
  • 1 cup light sour cream *see note below
  • 1 small lime *juiced
  • 1 teaspoon salt
  • ⅓ cup chopped cilantro leaves *loosely packed

Recipe notes:

Light sour cream: full fat also works but will likely result in a thicker sauce. I like using light sour cream because it has less calories! Greek yogurt can also be used, and is even lower cal. than light sour cream. 

Instructions

  • Preheat oven to 425°F.
  • Remove stems and seeds from peppers and cut them in half.
  • Line peppers evenly on a large baking sheet, leaving a little space between each.
  • Roast peppers for 25-30 minutes until skin is blistered. No need to flip the peppers over halfway, you can just leave them be.
  • Remove baking sheet from the oven and allow peppers to cool down enough that you can comfortably handle them.
  • Transfer roasted halves to a plastic bag. You can also use plastic wrap if you don't have baggies. This allows peppers to steam and will further loosen tough outer skin.
  • Remove peppers from the bag and peel outer skin away. Thorough is good, perfect is unnecessary. A few bits of unpeeled skin will be fine!
  • Add roasted/peeled poblano peppers, sour cream, garlic clove, cilantro, salt and lime juice to a food processor.
  • Puree ingredients on high speed for 30-60 seconds.
  • Transfer sauce to a serving dish and enjoy!

Storage instructions:

  • Transfer leftovers to an air-tight, food storage container and store in the refrigerator for 3-5 days.
