Classic broccoli cheddar soup has always been one of my favorite soups. However, it can take a lot of time to make on the stove top because you must be careful the pan doesn’t scorch.

I decided to convert my classic soup recipe into an Instant Pot recipe. I’m so glad I did because it’s so easy to make in an electric pressure cooker!

All you need are a handful of ingredients to make this easy weeknight meal. The easy recipe makes 4 individual portions of delicious, cheesy soup that pairs well with many dishes. It’s very similar to Panera’s Broccoli Cheese Soup, but my recipe is gluten free!

Ingredients

  • ¼ cup of unsalted butter
  • 1 cup of diced onion
  • 4 cloves of minced garlic
  • 4 cups of chicken stock
  • 5 cups of fresh broccoli florets
  • 1 cup of grated carrots
  • ½ teaspoon of sea salt
  • ¼ teaspoon of ground black pepper
  • 2 tablespoons corn starch or arrowroot powder
  • ¼ cup of cold water
  • 2 cups of heavy cream or half-and-half
  • 2 ½ cups of grated sharp cheddar cheese

Equipment

  • Knife
  • Cutting board
  • Measuring cups and spoons
  • Cheese grater or food processor
  • Mixing spoon
  • Small bowl
  • Whisk

By the Numbers: How to Make Instant Pot Broccoli Cheddar Soup

Follow these simple step by step instructions to learn how to make the most delicious broccoli cheddar soup in your Instant Pot electric pressure cooker.

Step 1: Saute Onions in Butter

Turn your Instant Pot onto Saute mode. Once hot, add ¼ cup butter and let it melt. Once melted, add 1 cup of diced onion and cook until it’s translucent.

Step 2: Add Minced Garlic

Press the cancel button, then stir in 4 cloves of minced garlic. Stir well, cooking until the garlic is fragrant.

Step 3: Add Stock, Broccoli, Carrots, Salt and Pepper

When the garlic is fragrant, you can go ahead and mix in 4 cups of chicken stock, 5 cups of small pieces of broccoli florets, 1 cup of grated carrots, ½ teaspoon of sea salt and ¼ teaspoon of black pepper.

Step 4: Pressure Cook Soup

Close the lid, check to make sure the pressure release valve is in the sealing position, press the High Pressure button and set it to a 1-2 minute cook time. When the cooking time is up, use a Quick pressure release to release all pressure. When all of the pressure is released and the pin drops, you can carefully open the lid.

Step 5: Make Cornstarch Slurry

In a small bowl whisk together 2 tablespoons of corn starch and ¼ cup of cold water until it’s well combined and smooth.

Step 6: Whisk Slurry Into Soup

Turn your Instant Pot back onto Saute mode (on high if your model has that feature) and slowly pour the cornstarch slurry into the pot. Use a heavy wooden spoon to stir constantly until your soup comes to a boil and begins to thicken.

I like to also break down the pieces of broccoli with my spoon as I stir it during this step.

Step 7: Add Heavy Cream

Once it’s thicker, turn your pot down to Saute Low (if it was on high), pour 2 cups of heavy cream into the broccoli soup and stir until well combined.

Step 8: Add Grated Cheese

Add 2 ½ cups of grated sharp cheddar cheese to the soup, about ½ cup at a time, and stir until it melts into the soup. Press the Cancel button to turn off your Instant Pot. Taste and adjust salt and pepper. If you used unsalted chicken stock, it may need more salt.

Step 9: Serve Broccoli Cheddar Soup

Either portion out into individual bowls or transfer to a serving bowl to set on the table. Top with additional grated cheddar if desired, then serve hot.

Tips for Making the Best Broccoli Cheddar Soup

Answers to all of your questions about making this Instant Pot Broccoli Cheese Soup recipe, including tips, substitutions and serving ideas.

Substitutions and variations

  • Use frozen broccoli. If you’d prefer to use frozen broccoli florets instead of fresh, increase the pressure cooking time by 1 minute.
  • Make it spicy. Add a pinch of red pepper flakes or cayenne pepper during cooking or a dash of hot sauce after cooking for soup with a little kick
  • Use your broth of choice. While I typically use my homemade chicken stock, you can also use chicken broth or vegetable broth from the grocery store.
  • Make it smooth. I like to leave the broccoli a little chunky, but you can use an immersion blender to make it smooth.

Serving ideas

There are lots of ways to enjoy this creamy soup, whether you serve it as a main course, side dish or appetizer:

Storage tips

Leftover soup should be stored in an airtight container and be consumed within 4 days.

You can also freeze room temperature soup for up to 2 months. Frozen soup should be defrosted in the fridge overnight then warmed on the stove top over low heat.
