Description

An easy recipe for homemade roasted tomato soup. Roasted tomatoes meld with sweet onion, fresh basil, and a splash of red wine to create a simple, yet satisfying soup, bursting with summer flavor. Vegetarian, gluten-free, and vegan-friendly.


Ingredients

Scale
  • 4 lbs tomatoes ¹
  • 1 Tbsp extra-virgin olive oil, plus more for roasting
  • 1 medium sweet or yellow onion, minced
  • 1 Tbsp fresh garlic, minced
  • 1012 fresh basil leaves, roughly-chopped
  • 34 sprigs fresh thyme, stems removed
  • 1/4 cup dry red wine
  • 23 tsp good balsamic vinegar
  • 23 cups chicken or vegetable broth ²
  • 1/2 tsp red pepper flakes, or to taste ³
  • Kosher salt and freshly-ground black pepper, to taste

Instructions

  1. Roast the tomatoes: Preheat the oven to 400℉. Line a rimmed sheet pan or large shallow baking dish with parchment paper. Set aside.
  2. Toss the tomatoes with just enough olive oil to lightly coat, and arrange in an even layer on your pan.
  3. Roast for 25-30 minutes, until the tomatoes have burst and are just beginning to shrivel. Remove from the oven, tent loosely with aluminum foil, and set aside.
  4. Make the tomato soup: Heat the olive oil in a medium-sized pot over medium heat until shimmering.
  5. Add the onion, and season generously with salt and pepper. Cook about 5 minutes, stirring occasionally, until softened and beginning to color. Add the garlic and cook, another 2-3 minutes.
  6. Add the roasted tomatoes (along with all the roasting juices from the pan), basil, and thyme. Stir to combine. Season with salt and pepper, to taste. Cook about 5 minutes.
  7. Add the red wine and balsamic vinegar. Stir to combine.
  8. Add the broth and red pepper flakes. When mixture comes to a boil, turn heat down to low, and let gently simmer, uncovered, for at least 30 minutes or up to an hour.
  9. Remove soup from heat and puree with an immersion blender or upright high-speed blender. Please be careful when working with the hot soup, which can splash or expand during blending. Work in batches as needed!
  10. Divide between bowls, and serve warm, with fresh basil and grated Parmesan cheese, or your favorite soup toppings. Enjoy!!


Notes

  • ¹ I like to use cherry tomatoes and/or smaller varieties like Campari or Roma, and/or cherry tomatoes, but feel free to use your favorite variety! A mix is also great. Cherry tomatoes can be left whole, and larger tomatoes can be halved or quartered prior to roasting.
  • ² Depending on how juicy your tomatoes are, and how thick you prefer your soup, feel free to adjust how much broth you add.
  • ³ The spice level can be adjusted by adding more or less or the red pepper flakes.
  • To store: best kept in a tightly-covered container in the refrigerator for 3-4 days.
