Keto Instant Pot® Soup (Low Carb)

Rated as 4.71 out of 5 Stars

"Just a recipe I threw together while entertaining my 6-month-old on a soccer night for my older kiddos when we had limited time. This is an alternative to fast food on busy hectic nights. I prechopped my veggies during nap time, so all I had to do was add them to the Instant Pot®! Garnish with green onions, Cheddar cheese, and bacon."

  1. Turn on a multi-cooker (such as Instant Pot(R)) and select the Saute function. Add olive oil, onion, and garlic; cook until browned, about 3 minutes. Add cauliflower, green bell pepper, onion powder, salt, and pepper. Pour in chicken stock; close and lock the lid. Select Soup function; set timer for 15 minutes. Allow 10 to 15 minutes for pressure to build.
  2. Release pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove lid. Add Cheddar cheese, half-and-half, turkey bacon, Dijon mustard, and hot sauce. Reselect Saute function; cook until bubbly, about 5 minutes.


  • Cook's Notes:
  • If using bacon instead of cooked turkey bacon, saute with the onion in step 1.
  • You can use gluten-free flour or cornstarch for a thicker soup (about 1 tablespoon dissolved in a small amount of water or 1/4 cup cold chicken stock), but this would not be keto friendly.

This is really good! As a diabetic I try to eat lower carb foods. I have steered away from cauliflower as it always has a fishy flavor to me. But this soup is amazing!

In an attempt to reduce dairy in my diet, I used Dayia brand cheddar cheese alternative and canned coconut cream. It turned out great! I would make this soup again.

The only change I made was before I added the whipping cream and cheese I puréed the Cauliflower then I put it back in the Dutch oven. Then added 2 cups of cheese and one cup of heavy whipping c...

This was really good! I’m on my third week of a keto diet so a made a few changes to lower the carbs a bit, and some just because of preference. First, I cooked about 6 slices of bacon in a cast...
