A cozy, comforting soup made by roasting ripe Roma tomatoes, garlic, and onions, then blending with fresh basil and cream for a silky smooth texture. Perfect for chilly evenings and easy weeknight meals.

Ingredients

Scale
  • 2 pounds (900g) ripe Roma tomatoes, halved
  • 1 cup packed fresh basil leaves
  • 4 large garlic cloves, peeled
  • 1 medium yellow onion, chopped
  • 3 tablespoons extra virgin olive oil
  • 3 cups (720ml) vegetable or chicken broth
  • 1/2 cup (120ml) heavy cream or half-and-half
  • Salt and freshly ground black pepper, to taste
  • Optional: pinch of red pepper flakes
  • Optional: 1 teaspoon sugar (if tomatoes are very acidic)

Instructions

  1. Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it.
  2. Halve the Roma tomatoes and place them cut side up on the baking sheet. Add whole garlic cloves and chopped onion pieces around them.
  3. Drizzle olive oil over the tomatoes, garlic, and onions. Sprinkle with salt and pepper, then toss lightly to coat evenly.
  4. Roast for 30-35 minutes until tomatoes are soft, slightly charred around edges, and garlic is golden.
  5. Transfer the roasted vegetables and their juices into a large pot. Add fresh basil leaves and pour in the broth.
  6. Bring the mixture to a gentle simmer over medium heat and cook for 10 minutes to infuse flavors.
  7. Remove from heat and carefully blend the soup using an immersion blender until silky smooth. If using a countertop blender, blend in batches and vent the lid slightly.
  8. Return the soup to low heat. Stir in the heavy cream or half-and-half and warm gently without boiling.
  9. Taste and adjust seasoning with salt, pepper, and optional red pepper flakes or sugar.
  10. Serve warm, garnished with fresh basil leaves or a drizzle of olive oil if desired.

Notes

If the soup is too thick, add more broth or water to reach desired consistency. Let roasted ingredients cool slightly before blending to avoid splatters. Use low heat when adding cream to prevent curdling. Adjust seasoning gradually, especially salt and optional sugar to balance acidity.
