This Slow Cooker Tomato and Vegetable Soup is a dream to come home to at the end of a busy day. It’s creamy, and fresh, and incredibly delicious.
And simple? It practically makes itself.
I love to make soups in the slow cooker. It’s virtually handsfree, and there’s something comforting with a bowl of steaming homemade soup that’s been cooking all day.
The Parmesan croutons is a nod to the perennial favorite: grilled cheese sandwiches. Although I must be honest. In our house, we tend to make both. And tomato soup isn’t quite the same without it.

2 (28-ounce) cans tomatoes (diced or whole)
1 tablespoon tomato paste
4 tablespoons butter
1 (15-ounce) can chicken broth (or vegetable)
large potato, peeled and diced
3 cloves garlic, minced
large onion, diced
1–1/2 teaspoon dried basil
1/2 teaspoon red pepper flakes
1 tablespoon sugar
salt and pepper to taste
1/3 – 1/2 cup cream (or milk)
For the Croutons:
4 cups French bread, cubed
1/4 cup grated Parmesan Cheese
For the Tomato Vegetable Soup:
Place tomatoes into a 6-quart slow cooker. Stir in the butter, tomato paste, broth, potato, garlic, onion, basil, red pepper flakes, sugar, and salt and pepper to taste, about 1/2 teaspoon each. Stir until combined.
Cover and cook on HIGH for 3-4 hours or on LOW for 7-8 hours. Puree with an immersion blender (or regular blender in batches) until desired consistency is reached. Stir in heavy cream; season with salt and pepper, to taste. Garnish with additional red pepper flakes, if desired, and Parmesan Croutons.
For the Parmesan Croutons:
Preheat the oven to 375 degrees. Lightly oil a baking sheet with olive oil or nonstick spray. In a bowl, add bread cubes; drizzle with olive oil and toss to coat. Spread in an even layer on the baking sheet; sprinkle with Parmesan cheese. Bake until crisp and golden, about 10-12 minutes, stirring halfway through. Let cool.
If using whole tomatoes, mash with the back of a spoon before cooking.
