Easy Crockpot Creamy Tomato Soup

I have made this homemade tomato bisque recipe with canned tomatoes but it takes a quite a bit of time at the stovetop.  With just six main ingredients this Crockpot tomato soup is quick for me to throw together in the morning.

At first I didn’t think I was going to like this when I had it at a restaurant. You see I am not a fan of raw tomatoes so I thought none of it was going to be a go for me, I was so wrong. Cooked is so my style and now it is one of my favorite Crockpot dinner ideas.

Let’s talk a little bit about slow cooking shall we?? First off I have a few different varieties and I love them all. Each one has an occasion to be used like….

1. This is my favorite 6 quart programmable one with a locking lid so it’s great for bringing to a potluck too.
2. I prefer not to use liners, but rather just spray olive oil inside before adding my food for easier cleanups.

Let me give you a peek of my pretty thang I bought recently. It goes with my kitchen so I can just leave it out on the countertop all the time. 😉

What is the difference between tomato soup and creamy tomato soup?

I mean it is obvious in the title but to make this creamy you would need to pour in some heavy cream or half and half. “Regular” would not have any dairy products in it and would have a stronger flavor.

If you’re a busy mom too who loves homemade tomato soup but doesn’t have a lot of time to do it, you’ll love this recipe. We have even more slow cooker soups here too. 😉

Ingredients

1. 2 cans of petite diced tomatoes
2. Half and Half or heavy cream works
3. Chicken stock or vegetable broth
4. Onion and garlic
5. A bit of all purpose flour to thicken, optional
6. Fresh basil & Oregano
7. Season with salt and black pepper when done

Variations

If you wanted to make it a bit heartier you could add stuffed frozen noodles noodles inside the last 30 minutes. Then it would qualify to be added to our Crockpot recipes with tortellini roundup.

You could add some heat to this if you really wanted to. I like it as is with the natural flavors shining through but using a bit of sriracha or some red pepper flakes it could really amp things up.

Can you use fresh tomatoes instead of canned?

If you have the time you could even use fresh tomatoes to make this easy Crockpot soup. Typically I use two cans of petite diced tomatoes though. Let’s just be honest here, we like really easy right. The difference between the two, other than effort, is the skin is softened in the can which is more pleasant.

Can you use heavy cream instead of half and half?

I use half and half to make it really creamy but if you had their heavy cream on hand instead that would work too, NO worries my friend. If you only had milk you could add 1 tsp of lemon juice per cup and let it sit to become buttermilk to thicken up too as another alternative.

How to Make Creamy Tomato Soup with Canned Tomatoes in Crockpot

1. Over low/medium heat on the stove heat your butter in a pan and add your diced onions and garlic cook. Saute for a few minutes until onions begin to soften.
2. Sprinkle your flour on to the softened, butter covered onions and stir until coated. Cook for an additional minute and turn heat off.
3. Add this onion roux mixture to your slow cooker.
4. Pour your two cans of petite diced tomatoes on top of that followed by your chicken broth, and then sprinkle in your spices and garlic if you wish to add that.
5. Stir gently just so everything is combined
6. Cover and cook on high for 3.5 hrs. If cooking on low set to 5.5 hrs. If you are able to stir halfway through it is best.

Top with parmesan cheese when served with crackers on top or with grilled cheese sandwiches.

How do you make soup smooth?

Lift lid and use an immersion blender to blend until smooth in the pot. Or use a ladle to put all contents into a blender. Set to puree for about 30 seconds or until all chunks are smooth. Pour mixture back into your slow cooker and set to low. Pour in your half and half, stir until combined. Put lid back on and allow to cook on low for 30 more minutes.

Can you freeze leftover soup?

To freeze leftover tomato soup, allow it to cool completely. When you reheat it, least 2 hours on the counter or in the fridge to thaw out. When microwaving after it’s thawed, do so in small stints 30 seconds, stir, 30 seconds so it doesn’t curdle If curdling occurs use a whisk to break it up. Can add a bit of fresh cream to thin it out too.

What should I serve with tomato soup?

1. Grilled cheese in air fryer is expected of course
2. Saltine crackers
3. Instant Pot cornbread or make air fryer cornbread
4. Our refrigerated biscuit pull apart garlic bread is amazing
