Gathering Your Ingredients for Slow Cooker Tomato Basil Soup
To make this delightful crockpot tomato soup, we’ll gather a few simple things. Each ingredient plays a starring role. The crushed tomatoes and tomato sauce form our rich base. Vegetable broth adds depth without making it too heavy. We need garlic for that essential aromatic kick. Dried oregano brings a touch of earthy goodness.
And of course, the star: fresh basil! Its bright, sweet aroma is what makes this basil soup truly special. A splash of heavy cream at the end makes it wonderfully smooth and luxurious. Salt and pepper? Just to make all those flavors sing. Don’t forget your optional toppings like crunchy croutons or melty cheese!

Essential Ingredients
Here’s what you’ll need:
- 2 (28 ounce) cans crushed tomatoes
- 1 (15 ounce) can tomato sauce
- 1 cup low-sodium vegetable broth
- 2 cloves garlic, finely minced
- 1 teaspoon dried oregano
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 cup freshly chopped basil
- 1/2 cup heavy cream
- Optional: croutons, shredded cheese for serving
Ingredient Notes and Substitutions
For the best flavor, I really can’t stress enough how wonderful fresh basil is here. It makes all the difference! If you can’t find vegetable broth, chicken broth works too, but it will change the vegetarian nature of the soup. You can also adjust the amount of basil to your liking; more if you’re a huge basil fan like me!
If you don’t have crushed tomatoes, whole peeled tomatoes you’ve broken up yourself are a good alternative. For a slightly different flavor profile, you could add a pinch of sugar to cut the acidity of the tomatoes. But really, the beauty of this easy tomato soup recipe is its simplicity!
Step-by-Step Guide to Making Your Slow Cooker Tomato Basil Soup
Now for the fun part! Making this slow cooker tomato basil soup is so simple, you’ll wonder why you didn’t try it sooner. It’s mostly hands-off cooking. Let your slow cooker do all the hard work for you!
Getting Started
First, grab your slow cooker. Open up those cans of crushed tomatoes and tomato sauce. Pour them right into the slow cooker. Add your vegetable broth, minced garlic, dried oregano, salt, and pepper. Give it all a good stir to combine everything nicely.

Slow Cooking Your Tomato Basil Soup
Now, put the lid on. You have two options for cooking. You can cook it on low for 6 to 8 hours. Or, if you’re in a hurry, cook it on high for 3 to 4 hours. Either way, the flavors will meld beautifully. The soup will thicken up nicely.
Finishing Touches for the Perfect Slow Cooker Tomato Basil Soup
About 15 minutes before you’re ready to serve, stir in the heavy cream and your lovely fresh basil. This keeps the basil bright and fragrant. For a super smooth soup, you can use an immersion blender here. Just blend until it’s silky. Serve it piping hot!
Tips for the Best Slow Cooker Tomato Basil Soup
Making this crockpot tomato soup is already a breeze, but a few little tricks will make it even better. Want that perfect silky texture? Or maybe you’re curious about jazzing up the flavor? I’ve got you covered!
Achieving the Ideal Texture
For a wonderfully smooth soup, an immersion blender is your best friend. Give it a quick blend before adding the cream and basil. If you don’t have one, carefully transfer batches to a regular blender. If your soup seems too thick, just add a splash more broth or water until it’s just right.
Flavor Boosters and Serving Ideas
Want to add a little extra zing? A tiny pinch of sugar can balance the tomato’s natural acidity. Sometimes, I’ll add a sprig of fresh thyme while it cooks for an extra layer of flavor. This basil soup is divine served with crusty bread for dipping. A grilled cheese sandwich on the side is pure comfort! Or perhaps a light green salad to complete the meal?

Storing and Reheating Your Delicious Slow Cooker Tomato Basil Soup
Got some leftover slow cooker tomato basil soup? Lucky you! Let it cool slightly. Store it in an airtight container in the fridge for up to 3 days. It freezes beautifully too! Portion it into freezer-safe containers or bags, leaving a little headspace for expansion. It’ll keep well for about 3 months.
To reheat, gently warm it on the stovetop over medium-low heat, stirring occasionally. You can also reheat individual portions in the microwave. If frozen, thaw it in the fridge overnight before reheating. It’s still delicious!
