  • Total Time: 1 hour
  • Yield: 6 servings

Ingredients

Main Ingredients

  • 4 poblano peppers, seeded and sliced in half
  • 2 tablespoons butter
  • 1 tablespoon all purpose flour
  • 2 leeks, cleaned and dark green sections removed, then finely sliced
  • 2 large cloves garlic, minced
  • 4 cups fresh corn kernels
  • 1 large russet potato, peeled and diced
  • 2 cups vegetable or chicken stock
  • 2 cups milk
  • 1 cup half & half, or heavy cream
  • ½ cup sour cream
  • 1 teaspoon salt
  • Freshly ground black pepper, to taste

Optional Toppings

  • Cilantro
  • Crushed tortilla chips
  • Avocado
  • Lime

Instructions

  1. Roast the Poblano Peppers: Preheat your oven to the broil setting. Place the seeded, halved poblano peppers on a baking sheet and broil them for about 20 minutes, turning halfway through until they are soft and their skins are blistered and charred.
  2. Peel the Peppers: Remove the peppers from the oven and place them inside a plastic bag to steam for 8-10 minutes. This will loosen the skins, making them easy to peel off. Once cooled, peel off and dice the peppers. Set aside.
  3. Sauté Aromatics: In a large heavy-bottomed pot over medium-high heat, melt the butter. Add the flour and cook for about 1 minute while stirring constantly to create a roux. Add the sliced leeks and minced garlic, cooking for 2 more minutes until fragrant and softened.
  4. Add Soup Ingredients: Stir in the cooked poblano peppers, fresh corn kernels, diced potato, stock, milk, and half & half. Bring the mixture to a boil, then reduce the heat to medium-low and simmer uncovered for around 30 minutes, or until the potatoes are tender.
  5. Finish the Soup: Remove the pot from the heat. Stir in the sour cream, salt, and freshly ground black pepper. Taste and adjust the seasonings as needed.
  6. Serve: Ladle the soup into bowls and garnish with optional toppings such as cilantro, crushed tortilla chips, avocado slices, and a squeeze of lime for brightness. Serve immediately to enjoy the creamy, smoky flavors at their best.

Notes

  • You can use vegetable or chicken stock depending on your preference or dietary needs.
  • For a richer soup, substitute half & half with heavy cream and add more sour cream if desired.
  • If you want a smoother texture, blend part or all of the soup after cooking.
  • The roasting and peeling of poblanos is key to developing the smoky flavor and removing bitterness.
  • Adjust the level of seasoning carefully, especially salt, as the sour cream and broth add varying saltiness.
