Instant Pot Broccoli Cheddar Soup

The rain was coming down sideways when I finally decided to attempt broccoli cheddar soup in my Instant Pot. My grandmother used to make the stovetop version every snow day, but I'd never tried adapting it to pressure cooking. That first batch was so lumpy I almost cried, but the flavor was unmistakably home. Now it's become my go-to when I need something that feels like a hug in a bowl.

Last winter my neighbor came over unexpectedly while this was simmering, and she literally stood in my kitchen until I agreed to share a bowl. She still texts me about it every time the temperature drops below forty degrees.

Ingredients

• 4 cups broccoli florets: Fresh is best here since frozen can get mushy under pressure, and dont be afraid to include the tender stems
• 1 medium carrot grated: This adds natural sweetness that balances the sharp cheddar perfectly
• 1 small onion diced: Yellow onions work best for their mellow flavor after cooking
• 2 cloves garlic minced: Add this right after the onion so it doesnt burn and turn bitter
• 3 cups vegetable broth: Low sodium is crucial since the cheese brings plenty of salt on its own
• 2 tablespoons unsalted butter: This creates the foundation for your roux and adds that restaurant quality richness
• 2 cups sharp cheddar shredded: Buy a block and grate it yourself because pre shredded cheese resists melting
• 1 cup whole milk: The fat content matters for texture so resist the urge to substitute skim
• 1/2 cup heavy cream: This is what makes it feel indulgent rather than just edible
• 1/4 teaspoon ground nutmeg: The secret weapon that makes people ask whats different
• 1/2 teaspoon paprika: Smoked paprika adds incredible depth but regular works fine too
• Salt and pepper: Wait until the end to adjust since cheese varies so much in saltiness
• 2 tablespoons all purpose flour: This creates the velvety texture that separates soup from flavored milk

Instructions

Build your flavor foundation:

Set the Instant Pot to Sauté and melt that butter until it foams slightly, then tumble in your onions and let them turn translucent and fragrant. The garlic only needs thirty seconds before it joins the party.

Create the roux:

Sprinkle the flour over the vegetables and stir constantly for one full minute until it smells nutty and coats everything in a pale paste. This step is what prevents grainy texture later.

Add liquid and vegetables:

Pour in the broth slowly while whisking to break up any flour lumps, then add the broccoli and carrot with your spices. The mixture will look thick but thats exactly right.

Pressure cook:

Seal the lid and cook on high pressure for exactly five minutes, then perform a quick release as soon as it beeps. The broccoli should be fork tender but not falling apart.

Blend to your preference:

Use an immersion blender right in the pot to reach your desired consistency, whether completely smooth or with some texture remaining.

Add the dairy:

Switch back to Sauté on low and stir in the milk and cream, then gradually add the cheese while stirring until melted and glossy. Taste now and adjust your seasonings.

Save

This soup became the thing I make for friends going through breakups, bad weeks, or just because Tuesday needed something warm. Theres something about that first spoonful that feels like being tucked in.

Making It Your Own

Sometimes I throw in diced potatoes with the broccoli if I want it more substantial, or cauliflower if I need to sneak in extra vegetables for picky eaters. A splash of hot sauce at the end wakes everything up without overwhelming the delicate flavors.

The Make Ahead Secret

This soup actually tastes better the next day when the flavors have had time to marry and deepen. Store it in the refrigerator without reheating, and warm gently over low heat while stirring constantly.

Serving Suggestions

Crusty bread is non negotiable for soaking up every last drop from the bottom of the bowl. A simple green salad with vinaigrette cuts through the richness beautifully.

• Top with extra shredded cheese while still hot for that melty crust
• Fresh chives or parsley add color and brightness
• A drizzle of good olive oil before serving feels surprisingly sophisticated

Save

Some nights are just meant for soup that requires you to stop everything and pay attention to the bowl in front of you.

Frequently Asked Recipe Questions

→ Can I make this soup without an immersion blender?

Yes, you can carefully transfer the cooled soup in batches to a standard blender. Leave the vent open to release steam, and blend until smooth before returning to the pot to finish with the cheese and cream.

→ How do I store leftovers?

Cool completely and refrigerate in an airtight container for up to 4 days. The soup may thicken when chilled—simply reheat with a splash of milk or broth to reach desired consistency. Freezing is not recommended as dairy can separate.

→ Can I use frozen broccoli instead of fresh?

Absolutely. Frozen broccoli works well in this preparation. No need to thaw first—just add directly to the pot. You may need to reduce the pressure cooking time by 1-2 minutes since frozen vegetables cook faster.

→ What type of cheddar cheese works best?

Sharp cheddar provides the most robust flavor. Pre-shredded cheese contains anti-caking agents that can create a grainy texture, so shredding your own block cheese yields the smoothest, most velvety results.

→ Is there a dairy-free alternative?

Substitute coconut milk or cashew cream for the dairy milk and cream. Use nutritional yeast or dairy-free cheese shreds for cheddar flavor. The texture will be slightly different but still satisfyingly creamy.
