Equipment

  • 1 slow cooker
  • 1 chopping board
  • 1 measuring cups
  • 1 measuring spoons
  • 1 blender optional for a smoother texture
  • 1 ladle

Ingredients
  

  • 2 tablespoons olive oil
  • 1 medium onion, diced
  • 2 cloves garlic, minced
  • 2 cans (14 oz each) diced tomatoes, with their juice
  • 2 cups vegetable broth
  • 1 teaspoon dried basil
  • 1 teaspoon dried oregano
  • 1 teaspoon sugar
  • to taste salt
  • to taste pepper
  • 1 cup heavy cream optional for a creamier soup
  • Fresh basil leaves for garnish (optional)

Instructions
 

  • In the slow cooker, heat olive oil using the sauté function (if applicable) or in a skillet. Add diced onion and sauté until translucent for about 3-4 minutes. Stir in minced garlic and cook for an additional minute until fragrant.
  • Add the sautéed onion and garlic mixture to the slow cooker. Pour in the diced tomatoes (with juice) and vegetable broth.
  • Season the mixture with dried basil, dried oregano, sugar, salt, and pepper. Stir well to combine all ingredients.
  • Cover the slow cooker and cook on low for 6 hours or on high for 3 hours.
  • Once the cooking time is complete, if you prefer a smoother texture, use an immersion blender directly in the slow cooker or transfer the soup in batches to a countertop blender. Blend until smooth, then return to the slow cooker (if using a countertop blender).
  • For a creamier soup, stir in the heavy cream just before serving. Allow the soup to heat through for an additional 10-15 minutes.
  • Serve the soup hot, garnished with fresh basil leaves if desired.

Notes

This soup can be stored in the refrigerator for up to 5 days. Reheat on the stove or in a microwave.
For a vegan version, skip the heavy cream or substitute it with coconut cream or a plant-based counterpart.
