This cozy slow cooker tomato basil soup with garden tomatoes is rich, creamy (without a drop of heavy cream), and has that deep, slow-cooked flavor that you just can’t rush. It turns the simplest ingredients into something that feels truly special.

Ingredients

Scale
  • 3 pounds garden tomatoes, roughly chopped
  • 1 large yellow onion, diced
  • 6 cloves garlic, smashed
  • 2 tablespoons olive oil
  • 2 cups low-sodium vegetable broth
  • 1/2 cup fresh basil, packed, plus more for garnish
  • 1 tablespoon balsamic vinegar
  • 1 teaspoon dried oregano
  • Salt and black pepper to taste
  • 1/4 cup heavy cream or full-fat coconut milk (optional)

Instructions

  1. Preheat oven to 400°F (200°C). Roughly chop garden tomatoes, dice onion, and smash garlic cloves.
  2. On a baking sheet, toss diced onion and smashed garlic with olive oil and a pinch of salt. Roast for 20-25 minutes until onions are soft and caramelized.
  3. Transfer roasted onions and garlic to a 5-6 quart slow cooker. Add chopped tomatoes, vegetable broth, dried oregano, and half of the fresh basil. Stir to combine.
  4. Cover and cook on low for 4-6 hours or on high for 2-3 hours, until tomatoes are broken down and flavors are melded.
  5. Remove lid and let cool for a few minutes. Use an immersion blender to puree the soup until smooth. Alternatively, blend in batches in a countertop blender, holding the lid down with a towel.
  6. Stir in remaining fresh basil, balsamic vinegar, and salt and pepper to taste. If using, stir in heavy cream or coconut milk. Adjust seasoning as needed.

Notes

Roasting the onions and garlic is crucial for deep flavor. Use the ripest tomatoes possible; canned San Marzano tomatoes are a good substitute. For a thicker soup, simmer on the stovetop after blending. Soup tastes even better the next day.
