Ingredient Breakdown

Ingredient	Notes
Broccoli	Fresh or frozen florets both work. Fresh allows you to chop pieces smaller for a more uniform texture.
Sharp Cheddar	Always shred from a block for the smoothest melt. Bagged pre-shredded cheese contains anti-caking agents that can make the soup grainy.
Carrots	Use shredded or finely diced. Pre-shredded carrots from the store save prep time.
Butter	Unsalted is preferred for better seasoning control.
Half and Half	A balanced choice — richer than plain milk but not as heavy as pure cream. A milk/cream combo works too.
Broth	Low-sodium chicken broth is the base. Swap in vegetable broth to keep it vegetarian.
Cornstarch + Water	Whisked into a slurry to thicken the finished soup. All-purpose flour can substitute if needed.
Garlic, Salt, Pepper, Paprika	Simple seasonings that round out the flavor beautifully.

Step-by-Step Instructions

Step 1 — Prep and Load. Chop your broccoli into small, bite-sized pieces and add them to the Instant Pot along with the shredded carrots.

Step 2 — Season the Pot. Pour in the broth, then add the butter, minced garlic, salt, black pepper, and paprika. Give everything a quick stir to distribute the seasonings.

Step 3 — Pressure Cook. Secure the lid, set the vent to Sealing, and select Pressure Cook (High) for 1 minute. Once the cycle ends, perform a quick release by carefully switching the vent to venting.

Step 4 — Add the Dairy and Cheese. Open the lid and stir in the half and half, followed by the shredded cheddar. Keep stirring until the cheese melts completely into the broth.

Step 5 — Make the Slurry. In a small bowl, whisk together cold water and cornstarch until completely smooth with no lumps.

Step 6 — Thicken and Serve. Switch the Instant Pot to Sauté mode and slowly pour in the slurry while stirring. Continue stirring frequently until the soup reaches your preferred consistency. Taste and adjust seasoning, adding extra cheese, salt, or pepper as needed.

Pro Tips for the Best Results

• Prefer a thicker soup? Reduce the broth to about 3 cups. You can always thin it out at the end, but starting with less gives you better control over the final texture.
• Want a smoother consistency? Use an immersion blender directly in the pot, or transfer a few ladles of soup to a countertop blender, blend until silky, and stir it back in.
• Boost the flavor depth by adding a pinch of cayenne, a dash of dry mustard powder, or a small squeeze of hot sauce — these all amplify the cheesy notes without overwhelming.
• Always shred your own cheese. This single habit makes a significant difference in the final creaminess of the soup.

Storage & Reheating

• Refrigerator: Keeps well for up to 5 days in an airtight container.
• Freezer: Freeze for up to 3 months in freezer-safe containers. Portioning into individual servings makes for easy grab-and-go lunches.
• Reheating: Warm over low heat on the stovetop, stirring often. Add a splash of broth or milk if the soup has thickened too much during storage.

What to Serve Alongside

• Crusty artisan bread — perfect for soaking up every last drop
• Bread bowls — a fun and filling presentation
• A crisp green salad — balances the richness of the soup
• Grilled cheese — because more cheese is always the right answer
• Crackers — simple, satisfying, and effortless

Frequently Asked Questions

Can I make this soup without an Instant Pot?

Absolutely. Make it on the stovetop by sautéing the vegetables in butter over medium heat for about 5 minutes, then adding the broth and simmering for 15–20 minutes until the broccoli is tender. Stir in the cheese, half and half, and slurry to finish.

Can I use frozen broccoli instead of fresh?

Yes! Frozen broccoli florets are a great substitute. The only difference is that your Instant Pot may take slightly longer to reach pressure. The final flavor and texture will still be delicious.

Can I make this soup vegetarian or vegan?

For vegetarian, simply swap chicken broth for vegetable broth — everything else stays the same. For a vegan version, use plant-based butter, unsweetened oat milk or full-fat coconut milk in place of half and half, and a good-quality vegan shredded cheddar. The texture may vary slightly, but it’ll still be delicious.

How do I thin out soup that’s gotten too thick?

Stir in a little warm broth or milk, a splash at a time, over low heat until you reach the consistency you like.

Can I add protein to this soup?

Definitely. Shredded rotisserie chicken, crispy crumbled bacon, or diced ham all make wonderful additions. Stir them in during the final sauté step.

Is there a way to make this soup lower in calories?

You can lighten it up by using whole milk instead of half and half, reducing the cheese quantity slightly, and using low-fat broth. The soup will be a bit less rich but still very flavorful.

Can I double the recipe?

Yes, as long as you stay within the maximum fill line of your Instant Pot (no more than ⅔ full for liquid-heavy recipes). The cook time stays the same, though pressurization will take a bit longer.

Why does the recipe only call for 1 minute of pressure cooking?

Broccoli cooks very quickly under pressure. Even a single minute is enough to fully cook the vegetables and develop flavor in the broth. The longer time comes from pressurizing and the final sauté step — not the actual cook cycle.
