It’s officially soup season. At least, according to my mother it’s officially soup season. About three weeks ago she hosted a soup party. I brought two kinds, she made three kinds, and we all gorged ourselves on soup galore one rainy Sunday evening. I can’t say that I didn’t enjoy it, because oh did I ever. I love me some soup. Particularly when it is creamy, rich, and cheesy.
Growing up I was never a tomato soup fan, and to this day I don’t like it straight out of the can. But creamy tomato-basil soup, that I can do. And by “do” I mean that I could eat it for breakfast, lunch, dinner, and midnight snack for days on end. Rain or shine. Summer, winter, fall, I’m impartial. My husband prefers that I wait until it’s actually cold outside to serve soup for dinner, and it takes all of my self control to put it off until September. In Utah, September weather is a gamble. (Actually every day’s weather is a gamble in Utah but let’s not get into that…) It may or may not be chilly in September but I can always count on the leaves changing color during this month and that’s when I start whipping up cozy soups.
This has to be in the top three or four best soup recipes I’ve ever made. Scratch that. The top two soup recipes I’ve ever tasted! It’s so good I just want to plunge my entire face into a giant bowl of it this instant. But alas, I shall refrain from such behavior. Instead I’ll just devote all of my soup-face-plunging energy to convincing you to make it yourself. It is E to the Z I tell ya. Just throw a few simple ingredients into the crockpot, set it, forget it, then remember it, and come back to finish it off in the last 30 minutes or so before you’re planning to serve it up. And if you really wanna get fancy, serve some crusty bread alongside this tomato basil parmesan soup for dipping and dunking – the kids will thank you later.
Okay you caught me, we don’t have kids . . . I’m the one who does all of the bread-dunking around here. C’mon you are too.

Slow Cooker Tomato Basil Parmesan Soup
Ingredients
- 2 15-ounce cans diced tomatoes
- 1 10-ounce can tomato sauce
- ¼ cup fresh basil, finely chopped
- 1 tablespoon minced garlic
- 1 tablespoon salt
- 1 teaspoon pepper
- 1 medium white onion, diced
- 1 cup heavy cream
- 4 cups chicken or vegetable broth
- 2 cups shredded parmesan cheese
Roux
- 3 tablespoons butter
- ¼ cup flour
- 1 cup heavy cream, see note
Instructions
- Add tomatoes, tomato sauce, and next 7 ingredients (through broth) to a slow cooker/crockpot. Cover and cook for 2 hours on high or 4-8 hours on low. (If you are home, give it a stir every now and then and scrape down the sides)
- About 30-40 minutes before serving transfer soup to a blender or food processor and puree until smooth, then return to crock pot.
- Prepare the roux. Begin by melting the butter in a medium sauce pan over medium heat.
- Add flour to melted butter and stir until flour clumps up. Slowly whisk in the heavy cream (or half & half) until mixture is thickened and smooth. Add roux and parmesan cheese to crockpot and stir to combine.
- Allow to cook another 20-30 minutes until cheese is completely melted. Give it a good stir before serving. Top with additional basil and parmesan cheese if desired.

I made this around Christmas to rave reviews from my family. I just made it again, this time I omitted the roux and extra cream to cut down the calories. It tastes just like last time! So yummy!
I need to make this ahead of time, and give to a new mom. Is there anything you would do differently? Since the recipe lists to complete the roux 30 minutes before serving I wasn’t sure if I should change anything. Thank you!
Hi Jennifer – I would probably just skip the slow cooker part and make this on the stove actually! I have readers write in and say that it works great on the stove. 🙂
Made this this afternoon. It was EPIC!!! Wow. So pumped I found your recipe!
How big of a crockpot did you use with this recipe. I have a pretty big one and was wondering if I’ll need to double this recipe. Thanks!
I used a 6 quart – you shouldn’t have any issues 🙂
Just finished making this! I have to say, as a Tomato soup LOVER, this is quite AMAZING!!!! Definitely one of the best tomato soups I’ve ever had!! Thanks sooo much! 🙂
Forgot to say I did it over the stove and it came out Great!
This is easy and Super delicious! I added spinach and nobody noticed once it was emulsified. Nummy!!!
Mmmmm, I’ll have to add spinach next time that sounds delicious!!
This looks wonderful! I can’t find heavy cream in my area. Can heavy whipping cream be used instead?
Is there anyway to skip the roux? I’m trying to watch what I’m eating and since there was already cream in the first part I really don’t want to have to add more.
You can skip it but the soup won’t be as thick!
Made this tonight and it was DELICIOUS!!!!!!!!!! All the kiddos loved it (and they are not fond of tomato soup). I only omitted the tablespoon of salt and had to substitute the fresh basil with dried (4 tsp of dried) because that is all I had on hand. Thanks for such a simple and tasteful meal!
This is by far the BEST tomato basil soup ever! It was simple to make and packed with flavor, can’t wait to have the leftover today. It is rare that I go back and add comments, but this was too good not to give credit for the great recipe.
Thanks for taking the time to comment – this is my FAVORITE soup and I’m glad that you enjoyed it too! 🙂
