How To Make Low Carb Broccoli Cheese Soup

Brown and Cook Brats

Brats are first browned in butter, then cooking is finished in the pressure cooker.

Using Saute (Medium heat) setting in your Instant pot, melt 2 tablespoons of butter, place bratwurst in the pot and cook only until outside because a golden brown, turning as needed to brown evenly.

**You are only giving the bratwurst a nice color - final cooking is done on high pressure (next step)

Turn the pressure cooker off. Pour beer over bratwurst. Lock lid and select High pressure (5 minutes cook time). Once cooking is complete, allow pressure to release naturally for 5 minutes, then do a quick pressure release. Once the valve drops, carefully remove the lid. Remove bratwurst and set aside.

**Save all remaining liquid in the pot and set aside in a bowl for later.

Cook Onions and Garlic

Using Saute setting (Medium heat) melt your remaining 2 tablespoons of butter. Add onions and cook until they are soft.

If onions are sticking to the pot, add up to 2 tablespoons of olive oil. If the pot gets too hot, turn heat to low.

Add garlic and cook for 2 minutes or until fragrant. Turn the pressure cooker off.

Cook Broccoli and Start Broth

Add chicken broth, the reserved beer brat liquid, and broccoli to the pot. Secure lid, set on High pressure and 1 minute cook time.

While you are waiting, slice bratwurst into ½" slices. Once the cycle is complete use a quick pressure release until the valve drops. Carefully remove the lid.

**As you can see in the picture, I used frozen broccoli. This worked perfectly, and with no change in cooking instructions. I tested this recipe with frozen broccoli and fresh and both turned out great!

Finish Soup

Using a slotted spoon remove ¾ of the broccoli and set aside. Using an immersion blender directly in the pot, blend the broccoli that remains in the pot with the broth until there are no more chunks.

Turn the pot on Saute Low. In a small bowl, whisk ½ teaspoons of xantham gum with a scoop of hot broth until there are no chunks. Pour back into the soup and blend. This is an optional step, but it helps the soup thicken without adding flour, as in traditional recipes.

Stir in cheeses and allow to melt. Slowly whisk in half and half, until blended.

Add your reserved broccoli and bratwurst back into the pot. Then add salt and pepper. Continue to heat only if necessary. Only heat to serving temperature, stirring frequently, and then turn the pot off.

The soup will thicken slightly as it cools. If you prefer a thicker soup, add ¼ to ½ teaspoons more of the xanthan gum. A little goes a long way, so be careful!

If you prefer a more liquid consistency, do not use xanthan gum; add additional broth until the desired consistency is reached. You may need to adjust salt and pepper to taste.

How to Serve Keto Cheddar Broccoli Soup

Ladle into bowls, sprinkle with pepper, and additional cheese. If you've got bread eaters in your house, serve with crusty sliced bread. (Low carb followers don't be tempted!) Enjoy!

Keto Broccoli Soup Recipe Variations

How can I make broccoli cheese soup that isn't low carb or keto?

• Use regular beer, not low carb
• Instead of Xantham Gum, use a ¼ cup of flour as a thickening agent whisked into ¼ cold water. Add into the soup and stir into the soup.

Can I make broccoli cheese soup on the stove?

Yes. Follow all of the same instructions for making the, except you would add the broccoli to your stockpot and cook on the stovetop, covered, until the broccoli is very tender. It is very easy to cook on the stove. Sometimes, it is even quicker because 20 minutes of the 50-minute cooking time with the pressure cooker are waiting for the pressure to build.

Can I substitute another ingredient for beer? 

Yes. You can substitute bone broth or chicken broth in place of the beer. This will lower the carbs in this recipe even more!

Kori's Tips

This recipe allows for chunkier broccoli pieces. If you would prefer a smoother soup, do not remove any broccoli as mentioned above, and blend all with an immersion blender.

Use any combination of favorite cheeses, up to 2-1/2 to 3 cups of cheese.

If you prefer a more liquid soup, do not use xanthan gum and add additional broth until the desired consistency is reached. You may need to adjust salt and pepper to taste.
