How To Make Instant Pot Broccoli Cheddar Soup

  1. Saute the onion and garlic: Turn the instant pot to SAUTE mode. Add the butter. When the butter is melted, add the diced onion and saute until it becomes tender. Then, add the garlic and saute for 30 second or until the garlic is fragrant and slightly softened. Press the CANCEL button. 
  2. Pressure cook the vegetables: To the instant pot, add the broccoli, carrots, salt, pepper, and nutmeg. Close the lid and turn the knob, sealing the lid. Cook on MANUAL high pressure for 1 minute. Once it’s finished, carefully use a quick release to depressurize. 
  3. Partially blend the vegetables: Open the lid of the instant pot carefully to let excess steam escape. Using an immersion blender, blend ⅓-⅓ of the soup depending on how thick you want your soup. Press SAUTE mode once again. 
  4. Thicken the soup: Whisk the cornstarch with the remaining broth until there are no lumps in the cornstarch slurry mixture and slowly add it to the soup once it begins to simmer. Stir to thicken, then press the CANCEL button. 
  5. Stir in cream and cheese: Stir in the cream and milk, then add the shredded cheese ½ cup at a time making sure to stir until it fully melts. Season with additional salt and pepper, then serve in bowls with french bread or crackers.  

Serve this soup in bread bowls for the ultimate comforting dinner.

Expert Tips

  1. Use freshly grated cheddar. Pre-shredded cheddar is often mixed with flour or potato flour to keep it from sticking together. This could make for a rubbery texture and taste. Freshly grated sharp cheddar is best in this instant pot broccoli cheddar soup recipe. 
  2. Using frozen broccoli. If you don’t have fresh broccoli florets, you can use frozen broccoli in it’s place. Just add it to the vegetable mixture and the instant pot will adjust the cooking time as it pressurizes. 
  3. Pressure cook time is 1 minute, however the time it takes for the instant pot to come to pressure will vary depending on the volume of the vegetables and their temperature. This usually takes about 20 minutes.
  4. Make sure you mix the cornstarch with broth before adding to the soup as the cornstarch may leave visible lumps in the soup if not mixed properly. 
  5. You can choose whichever milk you enjoy to go with the heavy cream such as 1%, 2%, or whole milk. 
  6. Since the cheese already contains salt, make sure you give it a taste test before adding more salt and pepper to balance the seasonings. This is also important if you are using salted butter. 

Variations

  • Gluten Free Broccoli Cheddar Soup: To make a gluten free broccoli cheddar soup, make sure there are no wheat ingredients in the cornstarch or shredded cheese. 
  • Keto Broccoli Cheddar Soup: This recipe is already low carb compared to traditional soups that contain beans and grains. Keep the carb count low by using lower sugar milk and omit the carrots if needed. 
  • Add protein. You can add chicken, tofu, or your favorite cooked meat to add more protein to the soup. 
  • Add spicy flavor. Make this a spicy broccoli and cheese soup by adding a pinch of cayenne pepper or red pepper flakes as a garnish. 
  • Use more veggies. You can saute some celery or cauliflower to add bulk and nutrition to the soup. 
  • Add cooked pasta. Cooked pasta makes a great addition to this soup to stretch it out and make it filling and satisfying.

Notes

Storing: Leftover cooked and cooled broccoli cheddar soup can be stored in an airtight container for up to one week. Reheat on the stovetop in a saucepan or microwave for best results.
Freezing: Unused cooled portions of soup are best frozen in individual bags or airtight containers and can be frozen for up to 4 months. After thawing in the fridge overnight, the milk and cheese may separate when thawing, so you may need to whisk in a bit of cornstarch or blend when reheating.
