Ingredients

  • 2 tbsp olive oil plus more for topping
  • 4 plum tomatoes cut in half
  • 1.5 lbs cherry tomatoes
  • 1 yellow onion roughly chopped
  • 6 cloves garlic whole
  • 4 sprigs fresh thyme or 1/2 tsp dried thyme
  • 1 cup vegetable broth
  • 1/4 cup heavy cream optional, plus more for topping
  • 1/4 tsp salt plus more to taste
  • 1/4 tsp pepper
  • 1 cup fresh basil divided; 1/2 cup goes in soup, 1/2 cup for garnish
  • 1 tbsp fresh oregano finely chopped; or 1/2 tsp dried oregano
  • Chili flakes optional garnish

Instructions

  • Preheat oven to 425 F. Add tomatoes, onion and garlic to a parchment-lined baking sheet and toss with olive oil and season with salt & pepper to taste. Add sprigs of fresh thyme, then roast for 30 minutes.
  • When tomatoes are done, let cool on the counter for at least 15 minutes, then add to a blender along with vegetable broth, heavy cream, salt & pepper, 1/2 cup of the fresh basil and oregano. Blend until smooth and creamy.
  • Serve in large bowls then drizzle extra olive oil and heavy cream overtop. Garnish with fresh basil leaves and a sprinkle of chili flakes if desired, then serve and enjoy!

Notes

To make this soup vegan, leave out the heavy cream.
Serve with crusty bread, mini grilled cheese sandwiches or a side salad.
If you want the soup to be even thicker, let it simmer for a bit on the stovetop.
Store the leftovers in the fridge for 5 days. Reheat in the microwave for 1-2 minutes or in a pot on the stovetop.
Freeze this soup without the heavy cream for up to 3 months. Defrost in the fridge overnight then reheat as normal.
