Heat olive oil in a saucepan over medium heat. Add chopped onions and sauté until they turn translucent.
Toss in the minced garlic and sauté for another minute until that tantalizing aroma fills the air.
Introduce those diced tomatoes to the party. Sauté them until they break down and release their juicy goodness.
Sprinkle in the dried basil, salt, and pepper, stirring to let those flavors mingle.
Pour in the vegetable broth and bring the mixture to a gentle boil. Let it simmer for about 15 minutes.
Time to blend! Carefully transfer the mixture to your trusty Vitamix blender. Blend until smooth, and you've got that velvety texture we all adore.
Pour the blended soup back into the saucepan and stir in the heavy cream. Heat it up, but don't let it boil.
Ladle this masterpiece into bowls, and you're ready to savor every spoonful.
