2 tbsp olive oil
1 medium onion, finely chopped
2 cloves garlic, minced
28 oz canned crushed tomatoes Shop
4 cups gluten-free vegetable broth Shop
1/2 cup fresh basil leaves, chopped
1/4 cup heavy cream or coconut milk (for dairy-free) Shop
1 tsp sugar (optional, to balance acidity) Shop
salt and freshly ground black pepper, to taste

Instructions

1 Heat the olive oil in a large pot or Dutch oven over medium heat until shimmering. Add the finely chopped onion and sauté for about 5-7 minutes, stirring occasionally, until softened and translucent. You should notice a sweet aroma developing.
2 Add the minced garlic to the pot and cook for another minute until fragrant, being careful not to burn it. Stir in the canned crushed tomatoes and the gluten-free vegetable broth. Bring the mixture to a gentle simmer.
3 Reduce the heat to low, cover the pot, and let the soup simmer for 20-25 minutes, until the raw tomato taste is gone and the onion is very soft. Stir occasionally to prevent sticking. The soup should be hot and fragrant.
4 Stir in the chopped fresh basil leaves and the heavy cream or coconut milk. If using, add the sugar to balance the acidity of the tomatoes. Season generously with salt and freshly ground black pepper to your liking.
5 Continue to heat the soup gently for another 2-3 minutes until warmed through, but do not boil after adding the cream. Taste and adjust seasonings as needed before serving this comforting gluten-free tomato basil soup hot.

Tips & Notes

For a smooth soup, purée it with an immersion blender before you stir in the cream or coconut milk.
Add the basil at the end, as step 4 does, and save a few leaves to tear over each bowl. Basil loses its aroma when it simmers.
Taste before you add the sugar. Canned tomatoes vary, and a pinch more salt often balances the acidity on its own.
