Slow Cooker Tomato Parmesan Soup
Servings: 6–8 servings
Ingredients
| Ingredient | Quantity |
|---|---|
| Crushed tomatoes | 2 (28-ounce) cans |
| Medium onion, finely chopped | 1 |
| Garlic, minced | 3–4 cloves |
| Vegetable or chicken broth | 4 cups |
| Heavy cream | 1 cup |
| Grated Parmesan cheese | 1 cup |
| Olive oil | 2 tablespoons |
| Dried oregano | 1 teaspoon |
| Dried basil | 1 teaspoon |
| Sugar | 1 teaspoon |
| Salt and pepper | To taste |
| Fresh basil, chopped (optional, for garnish) | — |
Directions
- Warm the olive oil in a skillet over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes. Stir in the minced garlic and cook for another minute or two until fragrant.
- Transfer the sautéed mixture to your slow cooker. Add crushed tomatoes, broth, oregano, basil, and sugar. Stir to combine everything well.
- Cover and cook on low for 6–8 hours or high for 3–4 hours, allowing the flavors to blend beautifully.
- About 30 minutes before serving, use an immersion blender to puree the soup until smooth. If you enjoy a bit of texture, only blend half.
- Stir in the heavy cream and grated Parmesan cheese. Let it cook for another 15–20 minutes until the cheese melts and the soup is hot and creamy.
- Taste and adjust seasoning with salt and pepper.
- Serve warm and, if you like, garnish with freshly chopped basil for a burst of freshness.
Variations & Tips
If you want a vegan twist, swap heavy cream for coconut or cashew cream and use nutritional yeast instead of Parmesan. You can also add roasted red peppers for a smoky touch. For extra protein, toss in shredded chicken or cooked Italian sausage during the final hour. Fresh herbs like thyme or rosemary bring a delightful change of flavor, while a handful of spinach blended at the end adds nutrition and a beautiful green hue without altering the taste.
This slow cooker soup is perfect for meal prep, cozy dinners, or serving guests — simple ingredients, big flavor, and pure comfort in every spoonful.
