Roasted Tomato Basil Soup

Bowl of Roasted Tomato Basil Soup

I love soup. It doesn’t matter to me what time of year it is. I will eat it anytime. I adapted this recipe for Roasted Tomato Basil Soup by Ina Garten from The Barefoot Contessa Cookbook. It can be made from grocery store or fresh tomatoes. Roasting the tomatoes first gives the soup a deeper, more complex flavor. I have used it as an appetizer as well as a main dish.

Fresh tomatoes from our garden are amazing in this soup. I usually use Roma tomatoes in the fall and winter months, and it is still really good.

Spread the tomatoes on a large rimmed sheet pan in a single layer and into a 400° oven.

While the tomatoes are roasting, sauté the onion, garlic, and red pepper flakes in butter and olive oil. I don’t use as much onion as the original recipe calls for. Use more if you’d like to.

Once the tomatoes are roasted, combine all of the ingredients in a large stockpot and simmer for about 40 minutes. This is even better with homemade chicken broth, which you can find a recipe for here.

Ina’s recipe says to use a food mill to blend all of the ingredients after the simmering is done, but I use my immersion blender. It is an amazing tool for soups and any other types of blending or smoothing. Using this blender keeps you from having to pour it out of the stockpot and into another container. You can find immersion blenders in the cooking section of most department stores. Here are a few examples. Mine was about $50, but you can probably find a good one for less.

The result is a beautiful soup with a very complex blend of flavors. It is seriously good, really beyond description. A great bonus is that it’s also very high in Vitamins A and C, and  low in calories. It can be kept in the fridge for several days and it also freezes really well.
