Ingredients

  • ½ cup raw cashews
  • 1 medium yellow onion, finely diced
  • 2 cloves garlic, minced
  • 4 cups vegetable stock (or chicken stock)
  • 1 (28 ounce) can of crushed tomatoes (or diced tomatoes)
  • cup sun-dried tomatoes
  • 1 (6 ounce) can of tomato paste
  • 1 teaspoon no-salt-added Italian seasoning
  • teaspoons kosher salt
  • 1 teaspoon honey (optional)

Optional Topping Suggestions

  • chopped fresh basil
  • parmesan cheese

Instructions

  • Place the cashews in a small bowl and cover with water. Set aside.
  • Place the onions, garlic, vegetable stock, crushed tomatoes, sun-dried tomatoes, tomato paste, Italian seasoning, salt, and honey (if using) into the base of a slow cooker, stirring to combine.
  • Cover and cook on high for 4 hours or low for 6 hours.
  • When the soup is finished cooking, drain and rinse the cashews. Place the soaked cashews into the slow cooker, stirring to combine.
  • Using an immersion blender, blend the soup until well combined and very smooth, about 2 minutes. If you don’t have an immersion blender, carefully ladle the cooked tomato mixture into a blender, working in batches. Make sure the lid is on tightly, cover with a towel, and blend until well combined and very smooth.
  • Serve with toppings, if desired.

Notes

  • Storing: This homemade tomato soup keeps well in the fridge for up to 4 days, in a sealed container. It also freezes well, store in a sealed freezer friendly container for up to 3 months.
  • Nut-Free: If you want a nut-free alternative, feel free to add a 1/3 cup of heavy cream in place of the cashews.
