Roasted Red Pepper Tomato Fennel Soup

This Roasted Red Pepper Tomato and Fennel Soup is an elevated yet easy take on the comforting classic, tomato soup. 

Roasted Red Pepper Tomato Fennel Soup

Tasting of the perfect blend of bell peppers and tomatoes but with a touch of fennel, this soup is perfect alone or served with a grilled cheese sandwich or simple cheese quesadilla. I love how the touch of bell pepper and smoked paprika gives it a Spanish-inspired flavor, almost like the gorgeous flavors of a romesco sauce but rebirthed into a beautiful bowl of soup. It’s also fantastic with simple toasted croutons on top! 

Roasted Red Pepper Tomato Fennel Soup

This recipe is a little more sophisticated than your usual tomato soup, thanks to the addition of fennel. It gives it some complexity by adding a pronounced sweetness, along with a very gentle licorice flavor that really livens it up a notch.

This Roasted Red Pepper Tomato and Fennel Soup is becoming a classic in my home (with grilled cheeses, of course) and I am sure it will be in yours!
