Equipment

  • Slow Cooker
  • Blender

Ingredients

Canned Tomatoes

  • 56 ounces canned diced tomatoes

Vegetables

  • 0.5 unit yellow onion, peeled and minced
  • 1 cup carrots, peeled and diced

Broth

  • 2 cups vegetable broth

Spices

  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • 0.5 teaspoon garlic powder
  • 0.5 teaspoon salt
  • 0.25 teaspoon black pepper
  • 1 unit bay leaf

Creaminess

  • 4 tablespoons butter
  • 1 cup half and half or whole milk

Instructions

  • Step 1: Prepare the Ingredients. Start by gathering all your ingredients. It’s best to have everything ready before you start cooking to streamline the process. Mince the onion and dice the carrots so they’re ready to go into the slow cooker.
  • Step 2: Combine Ingredients in the Slow Cooker. In your slow cooker, add the 56 ounces of canned diced tomatoes, minced yellow onion, and diced carrots. Pour in 2 cups of vegetable broth to create a comforting base for your soup.
  • Step 3: Add the Spices. Sprinkle in the 1 teaspoon of dried thyme, 1 teaspoon of dried oregano, ½ teaspoon of garlic powder, ½ teaspoon of salt, and ¼ teaspoon of black pepper. Toss in 1 bay leaf for an extra flavor boost.
  • Step 4: Add the Butter. Place 4 tablespoons of butter right on top of the vegetable mixture.
  • Step 5: Slow Cook. Cover the slow cooker and set it to cook on low for 6 to 8 hours, or on high for 3 to 4 hours.
  • Step 6: Blend the Soup. Once the soup has cooked, remove the bay leaf. If you prefer a smooth soup, you can use an immersion blender to puree everything directly in the slow cooker.
  • Step 7: Add Creaminess. After blending to your desired consistency, stir in 1 cup of half and half or whole milk to give the soup a luscious, creamy texture.
  • Step 8: Serve and Enjoy. Ladle the warm soup into bowls and serve immediately.

Notes

For an extra depth of flavor, consider roasting the diced carrots and onions in the oven before adding them to the slow cooker.
