I have been going soup crazy. I will list all my new soups below. What changed with this version was a follower asked for a keto vegetable soup with my brand new keto cornbread recipe. A very classic recipe that I had growing up with my grandmother for a little southern comfort.

Making the keto vegetable soup recipe

  1. To start, I suggest sourcing the freshest veggies as possible. You’ll need to dice all the vegetables up listed in the recipe below then proceed to next step.
  2. Now, using a bit of oil about one tablespoon add onion, red bell pepper and celery in a large pot. Sauté them a bit, about three minutes then add in minced garlic.
  3. Next, toss in a can of diced tomatoes and green beans. Using chicken broth pour over the veggies and bring to a very light simmer.
  4. Cover, then allow to cook for 10 minutes before adding cauliflower florets. You will season with salt, white pepper, Italian seasoning and a bay leaf. The salt and pepper will have to adjusted to taste.
  5. Now, after 20 minutes is up add in 2 tablespoons of tomato paste. Turn heat off then mix around and soup will naturally thicken up. Serve, you’ll get about 10 small bowls but it’s hard to gauge how much one person will eat so the nutrition label is a rough estimate.

Frequently Asked Questions (FAQs)

Can You Eat Vegetable Soup On The Keto Diet

The issue with vegetable soup is the traditional recipe has potatoes in it. Some recipes like to add noodles as well. Of course, you can’t have those things on the keto diet. So, that’s why this recipe is perfect for anyone living a low carb lifestyle.

Can You Freeze Vegetable Soup

Yes, you can freeze this soup. In fact, growing up my grandmother would make this huge pot. She would give some to my mother and we would have it for dinner. With storing leftovers she’d always freeze it for later. Reheated it remained fresh and tasted the same as the first day, if not better.

How To Thicken Vegetable Soup

I have seen people blend the soup up. My response to that is just no. Tomato paste is your best friend in this recipe. Traditionally, the starch from the potatoes give the soup a thickness. Without that you’ll end up with a broth. Keto vegetable soup doesn’t have to be this way. A quick addition of tomato paste gives it a nice thickness.
