Instant Pot Pumpkin Soup – Kalyn’s Kitchen

posted by Kalyn Denny on October 18, 2021

My Instant Pot Pumpkin Soup has sausage, onion, green pepper, pumpkin, cauliflower rice, cream, and just the right spices, and this soup is so, so good! We loved the soup and were glad it made a big pot of soup so we had leftovers.

If you’re a regular reader of this blog you probably know I’ve repeatedly said that my niece (and cooking assistant) Kara and I are not big pumpkin fans. But the last few years we’ve made a few pumpkin recipes that we both enjoyed, and recently I became intrigued with the idea of creamy pumpkin soup. Our first attempt at Instant Pot Pumpkin Soup was not a keeper, but we persevered! And we both absolutely SWOONED over the version I’m sharing with you here!

My Instant Pot Pumpkin Soup has amazing flavors from ground turkey sausage, green pepper, canned pumpkin, chicken broth, and heavy cream. It’s seasoned with onion, garlic, ground fennel, ground thyme, Spike Seasoning, and just a touch of white balsamic vinegar, and thickened with some frozen cauliflower rice. And this makes a big pot of soup, and I happily ate my share of the leftovers two nights in a row!

What ingredients do you need for this recipe?

Do you have to use White Balsamic Vinegar?

We used white balsamic vinegar to keep the lovely color of the soup from darkening. But if you only have regular balsamic vinegar it will be fine, just realize the color will be a little darker.

Is this a low-carb soup?

Pumpkin is a winter squash and it has some carbs. But this recipe makes a huge pot of soup and it’s a rich soup that you might serve as a first course. And after Kara and I both devoured a bowl when we tested the recipe we still had lots left, so I’m calculating the nutritional information at 10 servings, which comes out to 9.5 net carbs. If you have a larger servings and make it eight servings, each serving will have 11.6 net carbs. You can check out Low-Carb and Keto Instant Pot Soups for lots more ideas for low-carb soup.

What size Instant Pot did I use?

I use a 6 Quart Instant Pot for all my Instant Pot Recipes. You can use Instant Pot Recipes to see my growing collection of Instant Pot Recipes. You’ll find more Instant Pot Recipes on my other site, Slow Cooker or Pressure Cooker.

How to make Instant Pot Pumpkin Soup:

(Scroll down for complete printable recipe with tips and nutritional information.)

  1. Chop onion and green pepper.
  2. Turn Instant Pot to SAUTE, MEDIUM, and add butter. Add onion and green pepper and cook 2-3 minutes. Then add minced garlic, ground fennel, ground thyme, and Spike Seasoning, and cook a few minutes more.
  3. Turn Instant Pot to SAUTE, HIGH. Crumble ground turkey sausage into the pot and cook until sausage is all nicely browned, about 10 minutes. 
  4. We used this package of frozen cauliflower rice, just over two cups.
  5. Add cauliflower rice, canned pumpkin, and chicken stock to the Instant Pot.
  6. Lock the lid and set to MANUAL, LOW (or use Soup Setting), 10 minutes. 
  7. Let pressure NATURAL RELEASE for 10 minutes, then release the rest.
  8. Stir in white balsamic vinegar and heavy cream. Taste to see if you want more balsamic vinegar.
  9. Season to taste with salt and fresh-ground black pepper.
  10. Serve hot, with grated Parmesan if desired.
  11. I don’t think soups with cream freeze all that well, but this will keep in the fridge for several days.

  • 1 tsp. ground thyme 
  • 1 T  Spike Seasoning (or any all-purpose seasoning blend)
  • 2 lbs. ground turkey breakfast sausage
  • 2 15 oz. cans canned pumpkin puree (NOT Pumpkin Pie Filling which has sugar added)

  4. Turn Instant Pot to SAUTE, HIGH HEAT. Crumble the ground turkey sausage into the pot and cook until sausage is all nicely browned, about 10 minutes. Don’t rush this step, browning adds flavor.
  5. Add cauliflower rice, canned pumpkin, and chicken stock to the Instant Pot.
  6. Lock the lid and set to MANUAL, LOW (or use Soup Setting), 10 minutes. 
  7. Let pressure NATURAL RELEASE for 10 minutes, then release the rest of the pressure.

Notes

Use homemade chicken stock if you have some. You can use half and half or milk instead of heavy cream if you prefer, but the cream made this so good!

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
If you stick with a small serving size, this soup is a good option for any low-carb or Low-Glycemic diet, including Keto. Personally I’d eat it as a treat for the original South Beach Diet, but Pumpkin would be limited to Phase 2 or 3, and South Beach would definitely not recommend cream.
