Instant Pot Broccoli Cheddar Soup
This classic broccoli-cheddar soup adapts wonderfully to the Instant Pot. It’s a straightforward recipe that yields a creamy, cheesy soup that’s both comforting and satisfying.
I prefer using frozen broccoli because it softens quickly and evenly in the pressure cooker. If you choose fresh broccoli, allow a little extra cook time to reach the same tenderness.
Which Cheese is Best?
- For a smooth, melty texture, shred your own cheese from a block. Pre-shredded cheese often contains anti-caking agents that prevent it from melting cleanly.
- Use a sharp cheddar for the most pronounced flavor. A good quality medium cheddar can work, but sharp cheddar gives the soup the best balance against the broccoli.
- Add the cheese off heat (or after canceling the Sauté function) and stir gently. Overheating or boiling cheese can cause it to become grainy.

Does this soup freeze well?
- Yes. Cool completely before freezing and portion into individual containers for easier reheating.
- Thaw before reheating when possible and reheat slowly over medium-low heat for the best texture.
This pressure cooker version of Broccoli Cheddar Soup is quick and forgiving, making it a reliable choice when you want a hearty, homemade soup without fuss.

Instant Pot Broccoli Cheddar Soup
Equipment
-
6-quart Electric Pressure Cooker
Ingredients
- 3 Tablespoons Butter
- 2 teaspoons Olive Oil
- 1 small Onion, diced
- 1 large Carrot, shredded (about 1 cup)
- 1 small Potato (optional), peeled and diced
- 1 teaspoon Kosher Salt (or ¾ tsp table salt)
- ½ teaspoon Pepper
- ¼ teaspoon Nutmeg
- 1 teaspoon Garlic Powder
- 2 cups Chicken or Vegetable Broth, low sodium
- 1 teaspoon Chicken Bouillon
- 1 ½ lbs Broccoli Florets, fresh or frozen (chopped, about 6-8 cups)
To Thicken
- ¼ cup Flour
- ¼ cup Butter
To Finish
- 6 oz Sharp Cheddar Cheese, shredded (about 1 ½ cups)
- 4 oz Monterey Jack or Medium Cheddar Cheese, shredded (about 1 cup)
- 2 cups Half and Half
Instructions
-
Gather and prepare all ingredients: dice the onion, shred the carrot, peel and dice the potato if using, and shred the cheeses. Having everything ready makes the process smooth.
-
Set the Instant Pot to Sauté. When hot, add the butter and olive oil, then cook the onion for a few minutes until softened.
-
Stir in the grated carrot and potato (if using) and cook a minute to soften.
-
Add salt, pepper, nutmeg, and garlic powder. Cook for another minute, stirring to combine the spices.
-
Pour in the broth and stir to deglaze the pot.
-
Add the broccoli on top without stirring. Close and lock the lid, and set the steam release to Sealing.
-
Cancel Sauté, then choose Pressure Cook/Manual and set to High pressure for 3 minutes.
-
When cooking ends, let the pot rest for a 10-minute Natural Release. After 10 minutes, carefully quick-release any remaining pressure by turning the valve to Venting, then turn off the pot.
-
Once the pressure pin drops, open the lid.
-
Mash the vegetables with a potato masher for a rustic texture. For a smoother soup, use an immersion blender to purée to your desired consistency.
-
Combine the flour and ¼ cup butter in a microwave-safe bowl and heat for about 15 seconds, then whisk until smooth to form a quick roux.
-
Turn Sauté back on, stir in the roux, and cook until the soup begins to thicken.
-
Stir in the shredded cheeses until melted. Cancel Sauté, then add the half-and-half and stir until combined and heated through.
-
Taste and adjust seasoning with salt and pepper as needed.
-
Serve hot with crusty bread or your preferred accompaniment.
