This Smoked Tomato Basil Soup merges the smokiness of grilled tomatoes with the aromatic freshness of basil. A simple blend of onions and garlic forms the base, while the addition of chicken broth melds everything together. Cream adds a richness that will take this over the top. This soup is a play on traditional Tomato Basil Soup, but utilizes our Traeger Smoker to coax out deep, rich flavors from the tomatoes. The result is a comforting bowl that works as a warming winter meal or a chilled summer appetizer. It’s a straightforward recipe that delivers complex flavors with minimal fuss.

Traeger Smoked Tomato Basil Soup Recipe

Making this smoked tomato basil soup is a perfect opportunity to experiment with flavors and textures. Smoking the tomatoes offers a unique twist, infusing the soup with flavors that can’t be achieved with raw or canned tomatoes. It’s ideal for those looking to introduce a new standout dish into their meal planning or to impress guests with a homemade soup that has a gourmet edge.

This soup’s popularity also comes from its versatility; it can be served hot during colder months for a warming effect or chilled for a refreshing summer dish.

Common variations of this soup often include the incorporation of proteins or other vegetables. Adding shredded chicken or white beans can transform it into a more substantial meal, while the inclusion of carrots or red peppers can vary the flavor profile. Some might opt for a vegan version, substituting cream with coconut milk or omitting it entirely for a lighter broth.

Additional toppings and sides can also enhance the soup. A sprinkle of grated Parmesan or a dollop of pesto can complement the basil notes, while a side of grilled cheese or garlic bread makes this a whole meal. For those looking to add a kick, a dash of red pepper flakes or a spoonful of harissa will introduce a pleasant heat that cuts through the richness of the smoked tomatoes.
