Equipment You’ll Need for This Slow Cooker Creamy Tomato Soup

For the best results, here’s what you’ll need:

Slow cooker: Any 4-6 quart model works great. If yours has a timer function, even better!
Immersion blender:
This tool is perfect for pureeing the soup right in the slow cooker. Don’t have one? A regular blender works too—just be sure to let the soup cool slightly and blend in batches.
Knife and cutting board: For dicing the onion and prepping the garlic.

Pro Tip: If you’re in the market for a slow cooker, look for one with a “keep warm” function to make serving even easier.

Simple Ingredients for Slow Cooker Creamy Tomato Soup

This soup is all about pantry staples and a few fresh additions. Here are the stars of the show:

Whole peeled tomatoes: Canned whole tomatoes have the best flavor. Use quality brands like San Marzano for a richer taste.
Tomato sauce: This adds depth and a smoother texture.
Chicken or vegetable broth: Choose low-sodium to control the salt level. Vegetable broth keeps this vegetarian-friendly.
Heavy cream: Optional, but it gives that luscious creamy finish. For lighter options, try half-and-half or even coconut milk.

Tip: Already have diced tomatoes instead of whole? No problem—swap them in!

Slow Cooker Creamy Tomato Soup FAQs

Can I use fresh tomatoes instead of canned?

Yes! Replace the canned tomatoes with about 2 pounds of peeled and chopped fresh tomatoes. You may need to adjust the cooking time slightly.
