Ingredients

Instructions

  1. Step 1: Roast 2 medium poblano peppers over an open flame or under a broiler until the skin is blistered and blackened, about 5-7 minutes, turning occasionally. Place in a bowl covered with plastic wrap to steam for 10 minutes, then peel off skins, remove seeds, and roughly chop.
  2. Step 2: Heat 2 tbsp olive oil in a large pot over medium heat. Add 1 medium chopped yellow onion and sauté for 5 minutes until translucent.
  3. Step 3: Add 2 minced garlic cloves and cook for 1 minute until fragrant.
  4. Step 4: Stir in 4 cups fresh corn kernels and the chopped roasted poblano peppers, cooking for 3 minutes.
  5. Step 5: Pour in 4 cups vegetable broth, 1 1/2 tsp kosher salt, and 1/2 tsp black pepper. Bring to a boil, then reduce heat and simmer for 15 minutes.
  6. Step 6: Carefully transfer the soup to a blender in batches and puree until smooth, or use an immersion blender directly in the pot.
  7. Step 7: Return the soup to the pot, stir in 1/2 cup heavy cream, and warm gently over low heat until heated through but not boiling.
  8. Step 8: Serve garnished with 2 tbsp chopped fresh cilantro and lime wedges for squeezing over each bowl.
