Instant Pot Broccoli Cheddar Soup

The first time I made broccoli cheddar soup, I accidentally doubled the cheese because my measuring cup was buried under a pile of mail. Best mistake ever. Now it's the soup my youngest asks for on cold rainy days, the kind where everyone comes home with wet socks and red noses.

Last winter during that snowstorm that trapped us inside for three days, I made this soup four times. My neighbor came over with a loaf of crusty bread and we sat at the kitchen table watching the flakes pile up, eating bowl after bowl and talking about everything and nothing.

Ingredients

• Fresh broccoli florets: I learned the hard way that frozen broccoli turns weirdly watery in pressure cookers
• Sharp cheddar cheese: Buy the block and grate it yourself because pre shredded cheese has anti caking agents that prevent smooth melting
• Whole milk and heavy cream: The combination makes it rich without being overwhelmingly heavy
• Vegetable broth: Use a good quality brand or homemade because the liquid is the foundation
• Butter: Unsalted lets you control the final seasoning
• Flour: Creates the roux that gives the soup its silky body
• Garlic and onion: The aromatic backbone that makes your kitchen smell incredible
• Grated carrot: Adds natural sweetness and pretty orange flecks throughout
• Nutmeg: Just a quarter teaspoon transforms ordinary cheese soup into something special
• Paprika: Brings a gentle warmth and beautiful color

Instructions

Build the flavor foundation:

Set your Instant Pot to Sauté mode and melt the butter until it foams slightly. Toss in the diced onion and let it soften for 2 to 3 minutes until translucent, then stir in the garlic for just 30 seconds until fragrant but not browned.

Create the roux:

Sprinkle the flour over the onions and stir constantly for 1 full minute. The mixture will look pasty and thick, which is exactly what you want.

Add the liquids and vegetables:

Pour in the vegetable broth gradually while whisking to break up any flour lumps. Add the broccoli florets, grated carrot, paprika, nutmeg, salt, and pepper.

Pressure cook:

Seal the lid and set to Manual High Pressure for exactly 5 minutes. When the timer beeps, do a quick release of the steam.

Blend to your preference:

Use an immersion blender right in the pot to puree until completely smooth, or leave some texture for a more rustic soup.

Add the creamy finish:

Switch back to Sauté on Low setting. Stir in the milk and heavy cream, then gradually add the shredded cheddar while stirring until melted and silky smooth.

Save

My friend Jane came over recently during a rough week and I made this soup. She took one sip, closed her eyes, and said this tastes like being hugged. Sometimes food really is love.

Make It Your Own

Sometimes I stir in diced potatoes with the broccoli for a more filling soup. Other times, especially when cooking for picky eaters, I add a small head of cauliflower that disappears into the puree but adds extra creaminess without any detectable flavor change.

Texture Secrets

Ive discovered that partially blending the soup creates the best of both worlds. Leave about a quarter of the broccoli pieces whole, blend the rest, and you get satisfying chunks in an otherwise smooth base.

Serving Ideas

A warm baguette from the bakery section transforms this into a complete meal. The bread soaks up that cheesy broth beautifully.

• Croutons add a lovely crunchy contrast on top
• A drizzle of extra cream makes it restaurant fancy
• Fresh chives or scallions brighten the rich flavors

There's something deeply comforting about a soup that comes together this quickly yet tastes like it simmered all afternoon. Those are the best kind of recipes.

Recipe FAQs

→ Can I make this soup ahead of time?

Absolutely. This soup reheats beautifully and often tastes better the next day as flavors meld together. Store in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop over low heat, adding a splash of milk if needed to restore creaminess.

→ Can I freeze this broccoli cheddar soup?

Yes, though the texture may change slightly upon reheating. Freeze in portion-sized containers for up to 3 months. Thaw overnight in the refrigerator before reheating. The cream may separate slightly but will come back together with vigorous stirring.

→ What can I use instead of an immersion blender?

A standard blender works perfectly—just blend in batches, filling only halfway and venting carefully to release steam. You can also use a potato masher for a chunkier version, or skip blending entirely if you prefer a rustic texture with visible vegetable pieces.

→ How do I make this gluten-free?

Replace the all-purpose flour with cornstarch or a 1:1 gluten-free flour blend. When using cornstarch, whisk it with cold milk first to prevent clumping, then add to the pot. Always check your broth and cheese labels to ensure they're certified gluten-free.

→ Why does my cheddar cheese sometimes separate?

Cheese separates when overheated or added too quickly. Always remove the pot from heat or switch to the lowest setting before incorporating cheese. Add it gradually, stirring constantly, and use room-temperature shredded cheese rather than cold from the refrigerator.

→ Can I use frozen broccoli?

Frozen broccoli works well in a pinch, though fresh yields better texture. If using frozen, there's no need to thaw—just add directly to the pot. You may need to cook for an additional 1-2 minutes since frozen vegetables release more water.
