I started making this soup in my Instant Pot on a random Tuesday when I had a fridge full of broccoli and zero patience for standing over a stove. One bowl in, and I knew I’d never go back to the slow, stovetop version again. It’s rich, cheesy, and tastes shockingly close to the broccoli cheddar soup I used to order at restaurants.

I make this on repeat now whenever the weather turns cold or I just need something comforting fast. If you’ve been hunting for a healthy energy-packed comfort meal that still feels indulgent, this Instant Pot Broccoli Cheddar Soup Recipe is hits every mark.

Instant Pot Broccoli Cheddar Soup Recipe

Cooking Time

Prep Time: 15 minutes
Cooking Time: 15 minutes
Total Time: 30 minutes

Ingredients

1 tablespoon butter — helps soften the onion, celery, and carrots before pressure cooking
1 medium yellow onion, diced — builds the savory base flavor for the whole pot
2 celery ribs, diced — adds a subtle earthy crunch that balances the richness
2 to 3 carrots, diced or grated — brings natural sweetness and a pop of color
4 cups fresh broccoli florets, chopped — fresh works best here, frozen can turn watery once thawed
3 cups chicken broth — forms the flavorful liquid base the vegetables cook in
¼ cup butter — melted separately to build the roux that thickens the soup
¼ cup all-purpose flour — whisked with butter to give the soup its classic velvety texture
2 cups milk — adds creaminess without going overboard on heavy cream
8 ounces sharp cheddar cheese, freshly grated — shred it yourself, pre-shredded cheese won’t melt as smoothly
½ teaspoon salt — adjust to taste depending on how salty your broth already is
Freshly ground black pepper, to taste — adds a subtle warmth that plays well with the cheddar

Note: this recipe serves 6.

Equipment You Need

Instant Pot or electric pressure cooker — cooks the vegetables quickly under pressure and handles the sauté step too
Cutting board and sharp knife — for chopping the broccoli, onion, celery, and carrots
Box grater — for shredding the cheddar cheese fresh, which melts far better than the bagged kind
Whisk — helps smooth out the roux and prevents lumps once the flour hits the liquid
Ladle — makes serving the finished soup into bowls simple and mess-free
Measuring cups and spoons — keeps your ratios consistent for a properly thickened soup

How to Make Instant Pot Broccoli Cheddar Soup Recipe?

This soup comes together faster than you’d expect for something this creamy and comforting. Most of the work happens hands-off while the Instant Pot does the heavy lifting. Here’s exactly how I walk through it every time.

Sauté the Vegetables

Turn your Instant Pot to the sauté setting and melt the first tablespoon of butter. Add the diced onion, celery, and carrots, stirring occasionally until they start to soften. This only takes a few minutes and really builds the soup’s flavor foundation.

Add Broccoli and Broth

Pour in the chicken broth and add your chopped broccoli florets right on top of the softened vegetables. Give everything a quick stir so nothing sits at the bottom of the pot before you seal the lid.

Pressure Cook

Secure the lid, set the valve to sealing, and cook on high pressure for about 2 minutes. Once the timer ends, do a quick release so the broccoli doesn’t turn mushy from sitting in residual heat.

Make the Roux

While the pot vents, melt the remaining butter in a small saucepan, whisk in the flour, and cook briefly until it smells nutty. Slowly whisk in the milk until the mixture turns smooth and slightly thickened.

Combine Everything

Stir the roux mixture directly into the Instant Pot with the broccoli and broth. Set the pot to sauté again and let it simmer gently for a couple of minutes until everything comes together.

Melt in the Cheese

Turn off the heat completely before adding the shredded cheddar, then stir it in a handful at a time. Adding cheese off direct heat keeps the soup smooth instead of turning grainy or oily.

Additional Tips for Making This Recipe Better

I’ve made this soup more times than I can count, and here’s what I’ve learned along the way.

I always shred my own cheddar block instead of using the bagged kind, since it melts into the soup so much smoother.
I turn off the sauté function completely before stirring in the cheese, because direct heat is what makes cheese soups turn grainy.
I like to blend a portion of the soup with an immersion blender for a thicker, restaurant-style texture while still keeping some broccoli chunks.
I taste and adjust the salt at the very end, since the broth and cheddar both bring their own saltiness.
I never rush the roux step, because a properly cooked flour and butter mixture is what keeps this soup from tasting thin.

Common Mistakes to Avoid

I used pre-shredded cheese once thinking it would save time, but it turned my soup oddly grainy instead of silky.
I added the cheese while the pot was still on high heat, and it separated into a stringy, oily mess.
I skipped the quick release one time and let it sit, and my broccoli turned mushy and lost its color.
I didn’t cook my roux long enough, and the soup ended up tasting faintly of raw flour.
I overfilled my Instant Pot past the max fill line, which caused liquid to sputter out of the valve while venting.

How to Serve Instant Pot Broccoli Cheddar Soup?

I like ladling this into deep bowls and topping each one with an extra sprinkle of shredded cheddar so it melts slightly on top. A few cracks of black pepper and some crusty bread on the side turn it into a full meal instantly.

Crumbled bacon or a handful of croutons add a nice crunch if you want some texture contrast. This soup also makes a great starter before something heartier, and it pairs beautifully with a bowl of slow cooker chicken gnocchi soup if you’re setting out a cozy soup night spread for guests.

Variations

Make Ahead and Storage

You can chop all your vegetables and shred the cheese a day ahead of time, then store them separately in the fridge until you’re ready to cook.

Leftover soup keeps well in an airtight container in the refrigerator for up to 4 days, and reheats best gently on the stovetop over low heat.

Freezing isn’t ideal here since the dairy can separate and turn grainy once thawed, so I’d recommend enjoying this one fresh within a few days instead.

Why You’ll Love This Recipe?

This soup has become one of my most-requested dinners, and here’s why I think it’ll win you over too.

It’s fast: With the Instant Pot doing most of the work, this soup goes from raw vegetables to dinner in about 30 minutes total.
It’s easily customizable: Whether you want it lighter, potato-loaded, or protein-boosted, the base recipe adjusts to whatever you’re craving that day.
It’s kid-approved comfort food: The cheesy, creamy flavor wins over even picky broccoli skeptics in my house.
It reheats beautifully: Leftovers taste just as good the next day, making it a great option for easy weeknight lunches.
It skips the extra dishes: Since most of the cooking happens in one pot, cleanup afterward is refreshingly minimal.

FAQs

Can I use frozen broccoli instead of fresh?

Yes, frozen broccoli works in a pinch, though fresh florets tend to hold their shape and color better after pressure cooking.

Why did my broccoli cheddar soup turn out grainy?

This usually happens when cheese is added while the pot is still on high heat, so always turn off the sauté function first.

Can I make a healthy broccoli cheddar soup instant pot version?

Yes, you can reduce the butter, use low-fat milk, and skip the roux by blending in a cooked potato instead for natural creaminess.

How long does this soup stay fresh in the fridge?

It stays good for about 4 days when stored in a sealed container, though it’s best enjoyed within the first couple of days.

Can I turn this into a potato broccoli soup instant pot recipe?

Definitely, just add a couple of diced potatoes along with the broccoli before pressure cooking for a heartier, stew-like texture.

If you’re already building out a lineup of easy one-pot dinners, this pairs really nicely with something like a crock pot lentil soup for the nights you want a plant-based option in the rotation too.
