How to Make Mexican Keto Vegetable Soup

  • Prepare the ingredients. Dice the onion. Chop the bell pepper. Mince the garlic cloves. Cut the cauliflower head into florets. Chop the fresh cilantro (or parsley). Take the time to prep these ingredients beforehand and it makes your overall cooking time even shorter–perfect for busy nights.
  • Combine the ingredients. Add the olive oil, diced onion, chopped bell pepper, minced garlic cloves, cauliflower florets, frozen green beans, one can of diced tomatoes, vegetable broth, ground cumin, chili powder, chopped fresh cilantro or parsley, salt, and black pepper to a slow cooker and stir to combine.

Can I Freeze This Mexican Keto Vegetable Soup for Later?

You can absolutely freeze this Mexican vegetable soup. As a matter of fact, this recipe is a great candidate for making ahead of time in bulk in order to freeze it. You can have delicious Mexican vegetable soup on hand and ready to go all year long!

Make sure that you’re allowing the soup to cool completely after cooking and that you’re also keeping it sealed tightly inside freezer-safe airtight containers (or heavy duty freezer bags) before freezing. You’ll be able to keep this soup frozen like this for between 4-6 months.

As a final note, here are a few quick tips to keep in mind if you’re planning on freezing your soup:

  • Consider undercooking your vegetables slightly; veggies that are a little crunchy will have a better texture when they thaw out.
  • Make sure to leave about an inch of space between the soup and the top of the container/freezer bag; the soup will expand as it freezes.
  • Carrying on from the point above, you can also freeze the soup broth separately.
