This easy homemade roasted tomato basil soup from garden tomatoes is a velvety, rich soup that tastes like summer concentrated into a bowl. Roasting tomatoes whole saves time, deepens flavor, and creates a soup so delicious it converts even tomato-haters.
Don’t overcrowd the baking sheet—give tomatoes breathing room to roast properly. Always slice the top off the garlic head before roasting. Let tomatoes cool slightly before blending to avoid dangerous hot liquid splashes. Taste tomatoes before roasting; if bland, add a tablespoon of tomato paste during sauté step. Add basil during simmer step, not before, to preserve its bright flavor. Soup tastes even better the next day as flavors meld.
