The first truly cold evening of the season always makes me want a bowl of something warm and cheesy before I have even thought about dinner. This year, my daughter asked for the Panera-style broccoli cheddar soup she loves, and I decided to make it in the Instant Pot instead of standing over a stove for an hour.
This instant pot broccoli cheddar soup is my easy home-kitchen version. It uses fresh broccoli, sharp cheddar, a little heavy cream, and a simple flour slurry to create a thick, velvety soup without needing a roux or a long simmer. By the time it is done, the broccoli is tender, the cheese is fully melted, and the whole pot smells like a cozy bakery-cafe lunch. By Chef Elise, TasteOurDish.com.

Key Takeaways
- The Instant Pot cooks broccoli, onion, celery, and garlic together in about 5 minutes under pressure.
- A flour-and-water slurry thickens the soup after pressure cooking, so you control the final consistency.
- Sharp cheddar gives the best flavor, and it should be added off heat to prevent graininess.
- Heavy cream makes the soup richest, while milk works for a lighter version.
- Frozen broccoli can replace fresh, but reduce the pressure time slightly to avoid overcooking.
What Is Instant Pot Broccoli Cheddar Soup?
Instant Pot broccoli cheddar soup is a pressure-cooker version of the classic creamy broccoli and cheese soup. It combines broccoli florets, aromatic vegetables, broth, and cheese into a thick, satisfying bowl that comes together much faster than a stovetop simmer.
The Instant Pot method is appealing because it cooks the vegetables evenly under pressure in a short time, then lets you blend and thicken the soup right in the same pot. There is no need to watch a pot or stir constantly. You build flavor in layers, pressure cook, blend, then finish with cheese and cream off the heat.
This version is inspired by the Panera broccoli cheddar soup many people love, but it is a homemade copycat rather than the restaurant’s exact formula. The goal is the same comforting result: a thick, cheesy soup with visible broccoli pieces and a smooth, velvety base.
Answer capsule: Instant Pot broccoli cheddar soup is a creamy soup made by pressure cooking broccoli, onion, celery, and garlic, then blending and finishing with sharp cheddar and cream. It takes about 5 minutes under pressure plus natural release time. A flour slurry thickens the soup after cooking, and cheese is added off heat to keep it smooth.
Instant Pot Broccoli Cheddar Soup Ingredients
For the Soup Base
- 1 tablespoon unsalted butter
- 1 medium yellow onion, diced
- 2 stalks celery, diced
- 3 cloves garlic, minced
- 1 pound broccoli florets, fresh or frozen
- 3 cups low-sodium chicken broth or vegetable broth
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon ground mustard
- 1/4 teaspoon ground nutmeg
For Thickening and Finishing
- 1/4 cup all-purpose flour
- 2/3 cup cold water
- 2 cups sharp cheddar cheese, freshly shredded
- 1/2 cup heavy cream or whole milk
- 1/2 teaspoon hot sauce, optional
Freshly shredded sharp cheddar melts more smoothly than pre-shredded cheese, which often contains anti-caking agents that can make the soup grainy. Broccoli is also a good source of fiber and several vitamins, including vitamin C, according to the FDA nutrition information for raw vegetables. A medium stalk of broccoli provides about 45 calories, 3 grams of fiber, and meaningful amounts of vitamin C and potassium.
How to Make Instant Pot Broccoli Cheddar Soup
Step 1: Saute the aromatics
Turn the Instant Pot to Saute and melt the butter. Add the diced onion and celery and cook for 3 to 4 minutes until they soften and turn translucent. Stir in the garlic and cook for another 30 seconds until fragrant, then press Cancel to stop the Saute function.
Step 2: Pressure cook the broccoli
Add the broccoli florets, broth, salt, pepper, ground mustard, and nutmeg to the pot. Stir once to combine, then secure the lid and set the valve to Sealing. Cook on High Pressure for 5 minutes, then let the pressure release naturally for 10 minutes before quick-releasing any remaining pressure.
Step 3: Blend to your preferred texture
Open the lid carefully once the pin has dropped. Use an immersion blender to puree the soup directly in the pot, leaving some small broccoli pieces for texture if you like. If you do not have an immersion blender, transfer the soup in batches to a countertop blender, blend until smooth, and return it to the pot.
Step 4: Thicken with a flour slurry
Whisk the flour and cold water together in a small bowl until completely smooth with no lumps. Turn the Instant Pot back to Saute and bring the soup to a gentle simmer. Whisk in about half the slurry and stir until the soup thickens, adding more a little at a time if you want it thicker.
Step 5: Add cheese and cream off heat
Press Cancel to turn off the Saute function before adding the cheese. Stir in the shredded cheddar a handful at a time until each addition is fully melted and smooth. Then stir in the heavy cream or milk and the hot sauce if using. Taste and adjust salt and pepper before serving.

2 cups sharp cheddar cheese, freshly shredded
1/2 cup heavy cream or whole milk
1/2 teaspoon hot sauce, optional
Instructions
1. Turn the Instant Pot to Saute and melt the butter. Add onion and celery, cooking 3 to 4 minutes until soft. Stir in garlic for 30 seconds, then press Cancel.
2. Add broccoli, broth, salt, pepper, mustard, and nutmeg. Secure the lid, set valve to Sealing, and cook on High Pressure for 5 minutes. Let pressure release naturally for 10 minutes, then quick-release the rest.
3. Blend the soup with an immersion blender until smooth, leaving some broccoli pieces for texture if desired.

Notes
Use freshly shredded sharp cheddar for the smoothest melt; pre-shredded cheese can turn grainy.
For frozen broccoli, reduce pressure time to 3 to 4 minutes and add it straight from the freezer.
For a lighter version, replace heavy cream with whole milk or unsweetened almond milk.
Store in an airtight container in the refrigerator for 3 to 4 days; add a splash of milk when reheating if it thickens.

How This Version Compares to Panera
| Feature | Homemade Instant Pot Version | Panera Broccoli Cheddar Soup |
|---|---|---|
| Cooking method | Pressure cooker, about 5 minutes under pressure | Restaurant kitchen, batch-prepared |
| Cheese | Freshly shredded sharp cheddar | Proprietary cheese blend |
| Cream | Heavy cream or milk, adjustable | Fixed restaurant formula |
| Thickener | Flour-and-water slurry | Proprietary thickening method |
| Customization | Easy to adjust salt, cheese, and cream | Fixed recipe |
The homemade version is not the restaurant’s proprietary recipe, but it follows the same flavor map: broccoli, cheese, cream, and a thick, comforting base. The Instant Pot official broccoli cheddar soup recipe uses a similar approach with a flour slurry and a note not to boil after the cheese goes in, which is exactly the technique that keeps the soup smooth.
Why This Easy Version Works
The Instant Pot does two things well here. First, it cooks the broccoli and aromatics evenly under pressure in a short time, so you do not need to babysit a pot. Second, it keeps everything in one vessel, from sauteing to blending to finishing, which means fewer dishes and less cleanup.
The flour slurry is the key to getting a thick soup without making a traditional roux. Whisking flour into cold water first prevents lumps, and adding it gradually after pressure cooking lets you control exactly how thick the soup gets. I learned this the hard way once by adding all the slurry at once and ending up with something closer to pudding than soup.
Adding the cheese off heat is the other important detail. Cheese can separate or turn grainy if it gets too hot too fast. Stirring it in gradually after the Saute function is off, while the soup is still hot but not boiling, gives you a silky, fully melted result every time.
Instant Pot Broccoli Cheddar Soup with Frozen Broccoli
Frozen broccoli works well in this recipe if fresh is not available. Use the same amount by weight, about 1 pound, and add it straight from the freezer without thawing. Reduce the pressure cook time to 3 to 4 minutes since frozen broccoli is already partially blanched and cooks faster.
The texture will be slightly softer than fresh broccoli, but the flavor is nearly identical once the soup is blended and finished with cheese. This is a great option for busy weeknights when you want the soup ready without an extra trip to the store.
Instant Pot Broccoli Cheddar Soup No Cream
If you want a lighter version without heavy cream, replace it with whole milk, half-and-half, or even unsweetened almond milk. The soup will be slightly less rich but still creamy from the blended broccoli and melted cheese. The Instant Pot’s own broccoli cheese soup recipe uses almond milk in a lighter variation, which shows how flexible the base is.
For a dairy-free version, use a plant-based cheddar-style cheese and unsweetened oat or almond milk. The flavor will be different, but the pressure cooking and slurry method still work the same way.
Instant Pot Broccoli Cheddar Soup Healthy Tips
To make this soup a little lighter without losing the comforting character, use whole milk instead of heavy cream, reduce the cheese to 1 1/2 cups, and add an extra cup of broccoli. The blended broccoli itself adds body, so you may not miss the extra cream at all.
Serving it with a slice of whole-grain bread or a simple side salad turns it into a complete meal. If you want another cozy soup for the same rotation, my Creamy Potato Soup is another one-pot option that comes together quickly.
Instant Pot Broccoli Cheddar Soup for Meal Prep
This soup stores well in the refrigerator for 3 to 4 days in an airtight container. Reheat it gently on the stove or in the microwave, stirring occasionally. If it thickens too much in the fridge, add a splash of milk or broth when reheating to loosen it back up.
It also freezes reasonably well, though the texture can separate slightly after thawing. Whisk it well while reheating and add a little fresh cheese or cream to bring it back together. For a full comfort-food spread, pair it with my Chicken Broccoli Rice Casserole for a broccoli-themed family dinner.
5 Mistakes to Avoid
- Using pre-shredded cheese. The anti-caking agents can make the soup grainy instead of smooth.
- Boiling after adding cheese. High heat causes cheese to separate and turn oily. Always add it off heat.
- Adding all the slurry at once. Add it gradually so you can control the thickness and avoid a gluey result.
- Overcooking fresh broccoli. Five minutes under pressure is enough. Longer cooking turns it mushy and dulls the color.
- Skipping the natural release. Letting pressure release naturally for 10 minutes keeps the broccoli tender without turning it to mush.
If you enjoy one-pot comfort meals, my Corned Beef and Cabbage Recipe is another Instant Pot-friendly option that delivers big flavor with minimal hands-on time.
FAQ About Instant Pot Broccoli Cheddar Soup
Can I make instant pot broccoli cheddar soup with frozen broccoli?
Yes, frozen broccoli works well and saves prep time. Use the same weight as fresh, about 1 pound, and reduce the pressure cook time to 3 to 4 minutes since frozen broccoli is already partially cooked. Add it straight from the freezer without thawing for the best texture.
How do I make instant pot broccoli cheddar soup no cream?
Replace the heavy cream with whole milk, half-and-half, or unsweetened almond milk for a lighter version. The soup will still be creamy from the blended broccoli and melted cheese. For a dairy-free option, use a plant-based cheddar and oat or almond milk.
Is instant pot broccoli cheddar soup healthy?
It can be part of a balanced meal, especially if you use milk instead of heavy cream and add extra broccoli. Broccoli provides fiber, vitamin C, and potassium, according to FDA nutrition data. The cheese and cream add richness, so portion size and ingredient choices determine how light the final bowl is.
How long does instant pot broccoli cheddar soup last in the fridge?
Store it in an airtight container in the refrigerator for 3 to 4 days. Reheat gently on the stove or in the microwave, stirring occasionally. Add a splash of milk or broth if it thickens too much during storage.
Can I freeze instant pot broccoli cheddar soup?
Yes, but the texture may separate slightly after thawing. Freeze in airtight containers for up to 2 months, then thaw overnight in the refrigerator. Whisk well while reheating and add a little fresh cheese or cream to restore the smooth consistency.
What cheese is best for broccoli cheddar soup?
Sharp cheddar gives the strongest, most classic flavor. Freshly shredding a block of cheese yourself melts more smoothly than pre-shredded bags, which contain anti-caking agents. You can also add a little Parmesan for extra depth if you like.
Can I make this soup without an Instant Pot?
Yes, use a large pot on the stovetop. Saute the aromatics, add broccoli and broth, and simmer covered for 15 to 20 minutes until the broccoli is tender. Then blend, thicken with the slurry, and finish with cheese and cream the same way.
Conclusion
Instant Pot broccoli cheddar soup is one of those recipes that makes a weeknight feel a little more special without requiring much effort. The pressure cooker handles the cooking, the blender creates the silky base, and a handful of sharp cheddar finishes it off. If you love cozy one-pot meals, my Creamy Potato Soup is another easy option to keep in your rotation.
