A comforting and easy-to-make creamy roasted tomato basil soup paired with crispy grilled cheese croutons, perfect for cozy weeknight dinners.

Ingredients

Scale
  • 2 pounds (900g) ripe Roma tomatoes, halved (or two 28-ounce cans of whole peeled tomatoes)
  • 1 medium yellow onion, roughly chopped
  • 4 cloves garlic, peeled and smashed
  • 2 tablespoons olive oil
  • 1 cup (240ml) vegetable or chicken broth (low sodium)
  • 1/2 cup (120ml) heavy cream or coconut cream
  • 1/4 cup (10g) fresh basil leaves, chopped
  • Salt and freshly ground black pepper, to taste
  • 1 teaspoon sugar (optional)
  • 4 slices sturdy white or sourdough bread
  • 4 ounces (115g) sharp cheddar cheese, sliced
  • Butter, for spreading on bread

Instructions

  1. Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly oil it.
  2. Halve the Roma tomatoes and roughly chop the onion. Leave garlic cloves whole but smashed. Toss tomatoes, onion, and garlic with olive oil, salt, and pepper.
  3. Spread veggies evenly on the baking sheet in a single layer. Roast for 35-40 minutes, stirring halfway, until caramelized and slightly charred.
  4. While roasting, butter one side of each bread slice. Place cheese between two slices (buttered sides out) and cook in a skillet over medium heat until golden and cheese melts, about 3-4 minutes per side. Let cool slightly.
  5. Cut grilled cheese sandwiches into bite-sized cubes for croutons.
  6. Transfer roasted veggies to a blender. Add broth and blend until smooth, blending in batches if needed.
  7. Pour blended soup into a large saucepan. Stir in cream and chopped basil. Warm over medium heat for 5-7 minutes, adjusting salt and pepper. Add sugar if too acidic.
  8. Serve hot, topped generously with grilled cheese croutons.

Notes

Use canned San Marzano tomatoes if fresh are not in season. Add grilled cheese croutons just before serving to keep them crispy. For dairy-free, substitute heavy cream with coconut or cashew cream and use dairy-free cheese or omit croutons. When blending hot liquids, hold lid down with a kitchen towel to prevent splatters. Day-old bread works best for croutons. If soup is too thick, add a splash of broth. Fresh basil should be added at the end to preserve flavor.
