Storage Tips
This soup keeps very well in an airtight container in the refrigerator for up to four days. For longer keeping let the soup cool completely then store it in freezer-safe bags or containers and freeze for up to three months. Reheat gently on the stove while stirring often to preserve that smooth consistency.
Ingredient Substitutions
You can swap red peppers for yellow or orange for a slightly different flavor and color. If you have Roma tomatoes on hand use those for extra body. For a creamy dairy free version opt for an unsweetened coconut or cashew cream stirred in at the end. If you like some bite try adding a small pinch of dried chili flakes with the paprika.
Serving Suggestions
Pair with a slice of crusty gluten free bread or a toasted sandwich for a simple lunch. For a fancier starter drizzle with extra cream and a swirl of good olive oil. A bright arugula salad or lentil salad makes this a light but satisfying dinner.
Cultural and Historical Context
Roasting vegetables before pureeing them for soups is an old Mediterranean kitchen trick that creates deep flavor with minimal effort. This soup is inspired by both Spanish pimientos asados and classic Provençal tomato soups. In Spain and southern France these sorts of simple vegetable dishes celebrate the harvest and the comfort of gathering at the table.
Seasonal Adaptations
Choose ripe summer tomatoes for peak sweetness. Use jarred roasted peppers when fresh are not in season. In cooler months add a dash of cayenne for gentle heat.
