This easy slow cooker tomato soup is a creamy, dairy free version of the old classic. No canned soup could compare to the authentic and intense flavors in this homemade soup recipe!
Tomatoes and slow cookers are meant for each other. The more time tomatoes spend in a slow cooker, the richer and more intense their flavors become.
Lazy Slow Cooker Marinara Sauce is a perfect example. The suggested minimum cooking time is eight hours, but cooking a bit longer will just intensify the flavors.
The same principle applies when using a Crockpot to make this tomato soup. Longer cooking = more intense flavor. Low and slow is the way to go (sorry for the corny-ness).
Shopping list

Substitutions
- This recipe calls for roasted garlic, which adds a nice flavor. However, feel free to substitute regular pressed garlic.
- To add to the creamy texture, a small amount of coconut cream is used towards the end of cooking time. For those of you who just turned your nose up because you don't like coconut, relax! My avowed coconut haters couldn't taste a hint of it. You can, however, regular dairy cream, or skip it all together (but I don't recommend it).
Hints and hacks
- One of the most labor intensive steps in this recipe is chopping onions. Stay lazy like I do and skip this by buying frozen chopped onion in the frozen veggie section of your market. It is very inexpensive and saves a lot of tears!
- Basil is an important ingredient. Recommended amounts are included below for both dried and fresh. If possible, go with fresh.
- Recommended cooking time is at least 8 hours. You can serve it after about 6, but the flavors will become more intense the longer you cook. This is a great 12+ hour soup to make if you want to set it up before work (or a long day out) and eat when you get home.
- Anytime after 6 hours, use an immersion blender to pulverize into a smooth and creamy soup. If you are using a slow cooker liner (I am a HUGE fan of these!), be very careful! It is easy to catch a piece of the liner on the immersion blender and chop it up - essentially ruining the entire soup. To avoid this, don't let the blade of the blender fully touch the sides or bottom of the slow cooker.
- The recipe shows 2 pieces of Parmesan rind as an optional ingredient. I feel this adds a really great additional layer of flavor. However, if your goal is dairy free soup or vegan soup, feel free to omit.
- For laziest cleanup, a slow cooker liner is the way to go (although always fully optional). I buy them in bulk for the best per piece price. Click here to see that option.

Do you need the coconut creme?
admin says
Nope! You can definitely skip it! It just gives it a bit of a creamier feel and taste.
Sue Davidson says
Hi going to try this recipe. A couple of questions
1. Can you use unsweetened almond milk?
2. Would you just double everything if you want more servings?
3. Can this be made in a stock pot and then the next day put in a crockpot to warm up if taking to a family soup day pot luck?
Thank you, Sue

Hi Sue!
1. You can use unsweetened almond milk, but your soup will be a little thinner and less creamy. If you aren't a fan of coconut cream, you can try an oat creamer (I like Oatly's Barista blend) or an unsweetened almond creamer.
2. Yes! You can exactly double everything. If you use your crockpot, you would need to cook it for longer but not double the time. You would just need to keep an eye on it.
3. I don't see why you couldn't make this in a stock pot and then warm it in a slow cooker the next day. However, since I have never tried it, I can't share any advice on things like timing or temperature. If you decide to make it that way, I would love to hear how it goes!!
Family soup day potluck sounds like so much fun! I love that idea!!
