I love making soup in the Instant Pot, and I’m excited to add this Instant Pot broccoli cheddar soup to our collection of favorite Instant Pot soup recipes. Like my stove top Broccoli Cheddar Soup recipe, this Instant Pot soup is deliciously creamy, yet it’s made without cream. Instead of using heavy cream or cream cheese to add richness to this soup, a little bit of butter plus a gold potato give this soup the best texture and flavor. Once you add in the cheese, you won’t miss the cream at all.

Using your pressure cooker to make soup isn’t necessarily faster than cooking it on the stove, once you account for the time that it takes for the pot to reach pressure and then release pressure. However, you won’t have to worry about watching or stirring a pot on the stove. Once you get everything in the Instant Pot for this Instant Pot broccoli cheddar soup, it’s completely hands-off while the soup pressure cooks. 

Cheesy comfort food, here you come!

Instant Pot Broccoli Cheddar Soup Recipe Ingredients

Ingredients for instant pot broccoli cheddar soup recipe.

The ingredient list for this easy soup recipe is short and simple!

  • Butter & Olive Oil: I like to use a combination of butter and olive oil because the butter adds richness and the olive oil lightens things up.
  • Onion & Garlic: A small yellow onion and a few cloves of fresh garlic provide a base layer of flavor for the soup. We’ll sauté these aromatics briefly to enhance their flavor.
  • Vegetable Broth: I recommend using a low sodium vegetable broth. If you can’t find low sodium broth, reduce the amount of added salt in this recipe. You can substitute low sodium chicken broth if you do not need the soup to be vegetarian.
  • Italian Seasoning: This seasoning blend brings delicious flavor to the soup.
  • Salt & Pepper: For seasoning. Adjust the amounts to your tastes.
  • Yukon Gold Potato: My secret ingredient! A gold potato gives the soup a creamy texture, without adding any heavy cream.
  • Carrot: For flavor complexity and to sneak an extra veggie into the soup.
  • Broccoli: Of course! I use broccoli crowns and chop them into florets before adding to the pot. You can also chop up and add the broccoli stems, just use a vegetable peeler to peel off any tough outer layers on the stems first.
  • Cheddar Cheese: Sharp cheddar cheese will add the most flavor. It is best to buy a block of cheese and shred it yourself using a box grater. The pre-shredded cheese that you can buy at the grocery store often has a coating that prevents it from melting smoothly.

  8. Remove about 1 cup of broccoli pieces, if desired. You’ll stir these back into the blended soup to give it some added texture.

Storage & Reheating Tips

If you have leftover soup you can enjoy it for an easy lunch or dinner on another day. Here’s how to store and reheat this soup:

  • Refrigerator: Store soup in an airtight container in the refrigerator for up to 3 days.
  • Freezer: Let soup cool completely and then store in an airtight container in the freezer for up to 2 months. Thaw the soup overnight in the refrigerator before reheating. 
  • To Reheat: Reheat soup in a pot on the stove over low heat or reheat gently in the microwave. This soup tends to thicken up over time in the refrigerator. If needed, you can stir in a little more broth when reheating to thin it out. Since the soup has dairy (cheese) in it, you need to be especially careful when reheating the soup after freezing. Heating it over low heat and stirring it often can help to prevent the soup from curdling or separating as it reheats.

This Instant Pot Broccoli Cheddar Soup is cheesy, flavorful and easy to make. Make this delicious vegetarian soup recipe when you're craving healthy comfort food.

Ingredients

  • 1 tablespoon unsalted butter
  • 1 tablespoon olive oil
  • 1 small yellow onion (chopped, about 1 ¼ cups)
  • 3 cloves garlic (minced)
  • 3 ½ cups low sodium vegetable broth (plus up to ½ cup more, as needed)
  • 1 teaspoon Italian seasoning
  • ¾ teaspoon salt
  • ½ teaspoon black pepper
  • 1 medium Yukon gold potato (about ½ pound, chopped into ½-inch pieces)
  • 1 medium carrot (sliced into ⅛-inch thick half rounds)
  • 1 ½ pounds broccoli crowns (chopped into florets, about 8 cups chopped)
  • 1 ½ cups shredded sharp cheddar cheese

Instructions 

  • Heat the butter and olive oil in the Instant Pot using the saute function. Once the pot is hot, add the onion and saute for 3 minutes, stirring often.
  • Add the garlic and cook, stirring, for 30 seconds. Turn off the Instant Pot.
  • Pour in the 3 ½ cups of broth. Stir and scrape up any bits that are stuck to the bottom of the pot.
  • Stir in the Italian seasoning, salt and pepper. Then stir in the potatoes, carrots and broccoli.
  • Close the Instant Pot lid and move the steam release valve to the sealing position. Pressure cook on high pressure for 5 minutes. The Instant Pot will take about 15 minutes to reach pressure and then the cook time will start counting down.
  • When the cook time ends, allow the pot to release naturally for 10 minutes. Then carefully move the steam release valve to the venting position and wait for all of the remaining steam to escape. Once the pin drops down, open the Instant Pot lid.
  • Use a slotted spoon to remove about 1 cup's worth of broccoli pieces and set aside, coarsely chop into bite-size pieces if large.
  • Use an immersion blender to puree the soup in the pot until it is mostly smooth. (If you do not have an immersion blender, you can transfer the soup in batches to a countertop blender.)
  • Stir in the shredded cheddar cheese until melted. Taste and add more salt if needed, to taste. Stir in the reserved broccoli pieces. Serve.

Notes

  • Do not use store bought pre-shredded cheese, since it doesn't melt as smoothly.
