Ingredients
Method
Step-by-Step
- Heat the olive oil or unsalted butter in a large pot over medium heat. Add the diced onion and cook for 5–7 minutes, stirring occasionally, until softened but not browned.
- Add the minced garlic and cook for about 30 seconds, just until fragrant. Stir continuously so the garlic does not scorch.
- Stir in the chopped sweet peppers and diced potato, if using. Cook the vegetables for 3–5 minutes to begin softening them and coat them with the onion mixture.
- Pour in the broth, then add the kosher salt, black pepper, and smoked paprika. Bring the mixture to a boil.
- Reduce the heat, cover the pot, and simmer for 20–25 minutes. The peppers and potato should be completely tender when pierced with a fork.
- Blend the soup with an immersion blender until smooth. If using a countertop blender, work in batches, remove or vent the lid carefully, and remember that hot soup expands.
- Return the blended soup to the pot if necessary and stir in the heavy cream or half-and-half. Heat gently for 2–3 minutes, but do not let the soup boil after adding the cream.
- Taste the soup and adjust the salt and black pepper. Add lemon juice or sherry vinegar if the soup tastes overly sweet and needs a brighter finish.
- Ladle the hot soup into bowls and garnish with a little cream, croutons, chopped parsley, basil, chives, or smoked paprika. Serve immediately.
Notes
For deeper flavor, roast the peppers at 425°F/220°C until blistered and lightly charred before simmering them with the broth. Peel roasted peppers for an especially smooth texture. Vegetable broth keeps the soup vegetarian, while chicken broth gives it a fuller savory flavor.
