When my picky son requested I make him a tomato soup, I jumped at the opportunity to create a keto tomato bacon cheddar soup.

I’ll admit that while he was growing up at times I would get pretty frustrated with Matt’s finicky palate. However, these days it’s a rare thing that he pulls me aside and asks me to make him something to eat.

He is getting to an age where I recognize that these moments must be cherished before they fade into a precious distant memory.

With some tomato paste, chicken stock, bacon, cheddar cheese, and a little heavy cream you’ll have a heartwarming keto tomato soup recipe in minutes.

This homemade keto soup recipe is pretty straightforward and starts off with smoky bacon. Yes, bacon because we know everything goes so well with it. 

You’ll be frying up the bacon in the soup pot and then setting it aside to use as a garnish. Be sure to reserve the bacon fat to cook the onions. 

Once your onions are tender then it’s time to cook the garlic and add the tomato paste and dried Italian seasonings.

After that has had a minute or two to cook, you’ll add the chicken or vegetable stock and allow the soup to come to a simmer.

Next, after about 20 minutes or so it’s time to add the shredded cheddar cheese and heavy cream. Continue to cook and stir allowing the cheese to melt completely and thicken the soup, for about 10 more minutes.

Honestly, the smells of this soup alone cooking are sure to bring everyone into the kitchen.  Is there anything more comforting than a bowl of tomato soup? Personally, I don’t think so. 

Matt must have been around 12 years old when I pointed to the refrigerator and pantry and told him he had permission to feed himself. Frankly, it was freeing and it forced him to get creative.

I am a firm believer that allowing our children in the kitchen creates an appreciation for food like nothing else. Not to mention that it’s a life skill that they will always use.

However, this does not mean that I don’t enjoy cooking a meal that the ENTIRE family will enjoy. Today, I rarely enter the kitchen without a notebook. After all, you never know when a new recipe will be birthed.

The combination of bacon, cheddar cheese, and tomato is simply stunning and I am happy to report that Matthew loved the soup. Making me pretty confident that so will you.

Keto Tomato Bacon Cheddar Soup

Soup Toppings

  • ¼ cup of shredded cheddar cheese
  • ½ cup of sour cream
  • 6 slices of cooked crispy bacon
  • Fresh basil leaves or parsley 


  1. In a 4-quart pot, fry the bacon until crisp and set aside. Reserve 2 tablespoon of the bacon fat. 
  2. Add the chopped onion and sauté in the bacon fat until translucent.
  3. Then add the garlic and continue cooking until just soft.
  4. Next add the tomato paste, chicken or vegetable stock, and spices.
  5. Stir well until fully combined and allow the soup to simmer. After about 20 minutes add the cheddar cheese and heavy cream.
  6. Continue to cook and stir allowing the cheese to melt completely and thicken the soup, about 10 more minutes.
  7. Once the soup is done, serve into bowls and garnish with a dollop of sour cream, top this with cheddar cheese, bacon, and sprinkle of red pepper flakes.
  8. Store leftovers in the refrigerator for up to 5 days.


I do not recommend freezing this soup once the cheese and cream have been added. This is because it tends to separate. If you plan on freezing do so without adding these ingredients for up to 3 weeks. Once the soup defrosts and is slowly heated you can add the cream and cheese.

Note that the nutrition fact includes all the soup toppings.
