A recipe for rich, flavorful roasted tomato basil soup served with crispy grilled cheese croutons.

Ingredients

Scale
  • 3 lbs ripe tomatoes, halved
  • 1 large yellow onion, quartered
  • 4 cloves garlic, unpeeled
  • 3 tablespoons olive oil
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 4 cups vegetable broth
  • 1/2 cup fresh basil leaves, packed
  • 1/4 cup heavy cream (optional)
  • For Croutons: 4 slices white bread
  • 4 slices cheddar cheese
  • 2 tablespoons butter, softened

Instructions

  1. Preheat your oven to 400 degrees F (200 degrees C).
  2. Toss the halved tomatoes, onion quarters, and unpeeled garlic cloves with olive oil, salt, and pepper on a large baking sheet.
  3. Roast for 35 to 40 minutes, until the tomatoes are softened and slightly caramelized.
  4. Remove the garlic skins once cool enough to handle.
  5. Transfer the roasted vegetables to a large pot. Add the vegetable broth.
  6. Bring the mixture to a simmer over medium heat. Cook for 10 minutes.
  7. Remove the pot from the heat. Stir in the fresh basil leaves.
  8. Use an immersion blender or carefully transfer the soup in batches to a standard blender to blend until smooth. Return the soup to the pot.
  9. If using, stir in the heavy cream. Heat gently, but do not boil.
  10. To make the croutons, butter one side of each slice of bread.
  11. Place two slices of bread, butter-side down, in a skillet over medium heat. Top each with two slices of cheese, then top with the remaining bread slices, butter-side up.
  12. Grill for 3 to 4 minutes per side until the bread is golden brown and the cheese is melted.
  13. Remove the grilled cheese sandwiches and cut them into small, bite-sized cubes (croutons).
  14. Ladle the hot soup into bowls and top generously with the grilled cheese croutons.

Notes

  • For a smoother soup, strain the blended mixture through a fine-mesh sieve before adding the cream.
  • If you do not have vegetable broth, you can use chicken broth or water with a bouillon cube.
  • Roasting the tomatoes concentrates their natural sweetness, which is key to this recipe’s flavor.
