What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 2 pounds roma tomatoes halved
  • 1 medium yellow onion quartered
  • 4 cloves garlic
  • 2 cups vegetable broth
  • 0.5 cup fresh basil leaves
  • 3 tablespoons olive oil

Step by step instructions

Step 1: Roast the Vegetables

Preheat your oven to 400 degrees Fahrenheit. Arrange the tomatoes cut side up, onion quarters, and garlic cloves on a baking sheet. Drizzle with olive oil and roast for 40 minutes until caramelized and slightly charred at the edges.

Step 2: Cool and Transfer

Remove the roasted vegetables from the oven and allow them to cool for about 5 minutes. Transfer everything including any juices from the pan into your blender.

Step 3: Blend the Soup

Add the vegetable broth and fresh basil leaves to the blender with the roasted vegetables. Secure the lid tightly and blend on high for 60 to 90 seconds until completely smooth and velvety. Be cautious with hot liquids by starting on low speed.

Step 4: Heat and Season

Pour the blended soup back into a pot over medium heat and warm for 5 minutes. Season generously with salt and pepper and serve hot with a drizzle of olive oil.
