Why You’ll Love This Recipe
The holidays are upon us and that means lots of cooking! I love all the planning and cooking that goes into making holiday gatherings and meals special and memorable but I’m always ready for a little break from it afterwards. I’m also ready for more simplified meals and cooking.
Today’s recipe for Crock Pot Tomato Basil Soup is a perfect way to transition to simple, delicious meals. Emphasis on simple, because there isn’t much easier than making soup in the crockpot.
Ingredients Needed
- Petite diced tomatoes. I use canned tomatoes but you can also use chopped, fresh tomatoes.
- Vegetables. Celery, carrots, onions.
- Dried Oregano
- Fresh Basil Leaves. If using dried basil use half the amount of fresh.
- Chicken broth
- Flour
- Parmesan Cheese
- Butter
- Half and half. If you don’t have half and half available you can use half milk and half heavy cream.
- Salt and pepper to taste.
What is a Roux?
- This soup uses a roux to thicken the soup. A roux is a combination of melted butter and flour. The flour thickens while the fat, in this case butter, adds flavor and makes the flour dissolve in the soup without clumping. If you need a gluten free option, you can use cornstarch or a gluten free flour.
How to Make Crock Pot Tomato Basil Soup
- Put tomatoes, celery, carrots, onions and chicken broth into crock pot.
- Cover and cook on Low for 5-7 hours.
- Thirty minutes before serving make the roux.
- Melt butter over low heat in a skillet and add in flour.
- Stir constantly for about 5 minutes
- Slowly add in 1 cup of hot soup.
- Add in 3 more cups of soup and stir or whisk until smooth.
- Put all the liquid back into the crock pot.
- Stir and add Parmesan cheese, warmed half and half, salt and pepper
- Add in oregano and basil.
- Cover and let cook on low for another 30 minutes or until ready to serve.
Crock Pot Tomato Basil Soup Variations
- Less creamy: If you prefer your tomato soup less creamy, leave out the roux and the milk.
- Vegetarian: You can use vegetable broth instead of chicken broth.
- Dairy Free: Use coconut milk instead of half and half, it won’t be as creamy but still delicious. Use a dairy free butter substitute.
- Fresh Tomatoes: If you have an abundance of tomatoes in your garden you can use fresh diced tomatoes instead of canned tomatoes. You will need 5-6 cups of diced tomatoes.
Serve this with:
For a smoother, creamier soup.
If you prefer a smoother, creamier tomato basil soup, use one of these methods.
Blender Method:
- Allow the soup to cool first, so there is no steam.
- Place soup in a high powered blender, about halfway full.
- Remove the center cap of the blender lid and hold a towel over the blender lid.
- Blend. Pour into a bowl or back into the crock pot and repeat with remaining soup.
- Overfilling the blender can cause the soup to explode all over your kitchen!! Trust me on this one.
Immersion Blender:
Place the immersion blender right into the crockpot and blend until desired consistency.
Frequently Asked Questions

Can I freeze crock pot tomato basil soup?
Because of the dairy in it, I find that freezes better if you do so before adding in the roux and cheese.
Allow the soup to cool completely, then pour into a freezer-safe container or zippered freezer bags.
It will freeze for 3-6 months.
Thaw in the refrigerator.
Warm on the stove top or in the crockpot and continue with adding the roux.
How long will leftover soup last?
Stored in an airtight container in the refrigerator, it will last for 4-5 days.

This was really good. Out of our nine kids only 2 weren’t too sure of it. In my book that’s a good enough home run for me. AND I was able to use the veggies that I harvested out of my garden!
Thanks!

Have you frozen this, and if so, did it curdle when you rewarmed. I make crock-pot meals so I can freeze several servings, and I would love this soup on a day when I’m wearing ice packs. (Sometimes, it hurts to cook).
Leigh Anne says
I have not frozen it but have frozen other recipes with cream and they were fine.
