Make a rich, velvety tomato bisque using roasted tomatoes for deep flavor. This recipe is simple to follow and perfect for a comforting meal, especially when served with 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 heavy cream
  • 1/4 cup fresh basil leaves, chopped
  • 1 tablespoon butter
  • 4 slices sourdough bread, cubed (for croutons)
  • 4 slices cheddar cheese, shredded (for croutons)

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit (200 Celsius).
  2. Toss the halved tomatoes, onion quarters, and unpeeled garlic cloves with olive oil, salt, and pepper on a baking sheet.
  3. Roast for 30 to 35 minutes, until the tomatoes are slightly charred and soft. Squeeze the roasted garlic out of its skin.
  4. Transfer the roasted vegetables and garlic to a large pot. Add the vegetable broth.
  5. Bring the mixture to a simmer over medium heat and cook for 10 minutes to let the flavors combine.
  6. Carefully transfer the soup mixture to a blender (or use an immersion blender) and blend until completely smooth. Return the soup to the pot.
  7. Stir in the heavy cream and chopped fresh basil. Heat gently, but do not boil. Taste and adjust seasoning if needed. This is your rich and creamy soup base.
  8. While the soup heats, prepare the croutons: Melt the butter in a skillet over medium heat. Add the bread cubes and toast until golden brown on all sides. Remove from heat.
  9. Stir the shredded cheddar cheese into the warm bread cubes until melted and gooey. These are your grilled cheese croutons.
  10. Ladle the hot tomato bisque into bowls and top immediately with the grilled cheese croutons.

Notes

  • Roasting the tomatoes is the secret to developing a deep, sweet flavor in your bisque.
  • For an extra smooth texture, press the finished soup through a fine-mesh sieve before adding the cream.
  • Serve this with your favorite grilled cheese sandwich for the classic pairing.
