Roasted Tomato-Basil Soup

Roasted tomato-basil soup is one of my favorite things to make when I have a big harvest of tomatoes, and this is a great twist on the traditional recipe. It still includes fresh tomatoes, but instead of cooking them into submission, you roast them in the oven until they’re nice and soft. The time in the oven gives the soup its rich flavor and is also a wonderful way to bring out the natural sugars of tomatoes and add an extra level of flavor.

This roasted tomato basil soup is luxurious yet simple. Tomatoes and basil are a classic duo, and pairing them together makes for a sumptuous soup that can be served hot or cold.

Personally, I like to make it in late summer when fresh ripe red tomatoes are coming into season, or in the fall and winter with my canned tomatoes. It’s an easy way to capture the essence of one of my favorite flavors at its peak and then enjoy it all year long.

Having great homemade roasted tomato-basil soup ready to go in my freezer is fantastic when I don’t feel like cooking or when unexpected company comes. This recipe freezes very well so if you’re planning ahead, simply double all ingredients and freeze whatever you don’t eat right away.
