This amazing instant pot broccoli cheese soup is the ultimate comfort food and is so easy to prepare with a pressure cooker (or crock-pot!) Broccoli cheddar soup will surely become a family favorite, plus it's low carb, keto, gluten free, and vegetarian too!
Melt the butter in your instant pot with the saute setting on high
Saute the diced onions for 3-4 minutes, add minced garlic and cook for 30 more seconds
Add the broccoli, salt, pepper, cayenne pepper, and chicken broth to the instant pot. Cook on manual high (or pressure cook depending on your model) for 1 minute. Immediately do a quick release.
Stir in ½ cup of cream cheese until melted. Add the whipping cream and stir until the cream of broccoli soup is heated through.
Stir in the shredded cheddar cheese a ½ cup at a time until melted. Make sure it's melted before adding another ½ cup. This prevents cheese clumping. Serve immediately. Enjoy!
Slow Cooker
Combine the broccoli, garlic, and onion in a crock-pot. Add the chicken stock, salt, pepper, and cayenne pepper. Set your slower cooker to the LOW setting for 4-5 hours.
After 4+ hours when the broccoli and vegetables are cooked through, you'll need to turn the heat to HIGH to finish cooking the soup.
We HIGHLY recommend grating your cheese from a block and not using pre-shredded cheese. Pre-shredded cheese is mixed with potato starch and it often doesn't melt very well. You'll get much better results if you grate your own cheese.
Mix in the shredded cheddar cheese a little at a time, if you stir it all in together cheese has a tendency to clump and stick. Take about a ½ cup of cheese at a time, and stir until it's melted before adding another ½ cup of cheese.
Stir in the cream cheese until completely melted.
Add the whipping cream and stir to combine. Serve immediately. You can substitute half n half if you want a soup slightly less rich.
The broccoli cheddar soup thickens upon standing if it's thicker than you prefer simply add a little chicken broth until it's the desired consistency. Enjoy!
Notes
Whipping cream does not curdle under pressure but if you're trying to lighten the soup up a bit and want to swap half and half or milk, stir it in after pressure cooking.To keep the soup keto friendly and low carb, look for 0 carb dairy products and be sure to shred the cheese from a block instead of buying pre-shredded.Shredded cheese from a block works best in the recipe and melts better since pre-shredded packaged cheese is covered with potato starch and doesn't break down as well.Feel free to swap out the vegetables for cauliflower to make a cauliflower cheese soup or change the type of cheese you're using.
