How to Make Cheddar Broccoli Potato Soup (Step by Step)

Learning how to make cheddar broccoli potato soup comes down to a few simple stages: building flavor, cooking the vegetables, and melting the cheese.
 
Here’s how the process breaks down.
 

1. Start With a Flavorful Base

Every good cheddar broccoli potato soup starts with aromatics.
 
Melt a few tablespoons of butter in a large pot over medium heat, then add diced onion and cook until soft and translucent.
 
Toss in some minced garlic and let it cook for just 30 seconds until fragrant.
 
This base is what gives the soup its depth, so don’t rush this step.
 

2. Thicken With Flour, Then Add Broth

Sprinkle a quarter cup of all-purpose flour over the onions and butter, and stir constantly for about a minute.
 
This roux is what thickens your cheddar broccoli potato soup later on.
 
Slowly whisk in about four cups of chicken or vegetable broth, making sure there are no lumps.
 
Then add two cups of milk or half-and-half for creaminess.
 

3. Add the Potatoes and Simmer

Peel and dice about three medium russet potatoes, then add them to the pot.
 
Bring everything to a gentle simmer and let the potatoes cook for about 15 minutes until they’re fork-tender.
 
Russets break down nicely and give the soup body, but Yukon Golds work great too if you want a silkier texture.
 

4. Stir In the Broccoli

Once the potatoes are tender, add about two cups of chopped fresh broccoli florets.
 
Let them simmer for 5 to 7 minutes, just until they’re bright green and tender-crisp.
 
Overcooking the broccoli turns it mushy and dull, so keep an eye on it.
 

5. Melt In the Cheddar

Turn the heat down to low, then stir in two cups of freshly shredded sharp cheddar cheese a handful at a time.
 
Keep stirring until each addition melts completely before adding more.
 
This is the moment your cheddar broccoli potato soup comes together, so take it slow here.
 

Tips for the Best Cheddar Broccoli Potato Soup

A few small details make a big difference when you make cheddar broccoli potato soup at home.
 

1. Shred Your Own Cheese

Pre-shredded cheese is coated with anti-caking agents that keep it from melting smoothly.
 
Grate a block of sharp cheddar yourself, and your soup will turn out smoother and more velvety every time.
 

2. Keep the Heat Low When Adding Cheese

High heat can cause cheese to break down and turn grainy.
 
Once the cheddar goes in, keep the pot on low and stir gently until it’s fully incorporated.
 

3. Mash Some Potatoes for Body

If you like a thicker cheddar broccoli potato soup, use a potato masher to crush a few of the cooked potatoes right in the pot before adding the broccoli.
 
That gives you a creamy base without any extra cream or cornstarch.
 

Easy Variations to Try

Once you know how to make cheddar broccoli potato soup, you can start tweaking it to suit your taste.
 

1. Make It Loaded

Top each bowl with crispy bacon crumbles, sliced green onions, and an extra pinch of cheddar for a loaded baked potato feel.
 

2. Add Ham or Chicken

Diced ham or shredded rotisserie chicken turns this soup into a heartier meal that’s filling enough on its own.
 

3. Go Spicy

A pinch of cayenne or a dash of hot sauce gives the soup a subtle kick that pairs beautifully with the sharp cheddar.
 

So, How Do You Make Cheddar Broccoli Potato Soup?

You make cheddar broccoli potato soup by simmering potatoes and broccoli in a buttery broth base, then stirring in freshly shredded sharp cheddar over low heat until it melts into a rich, creamy soup.
 
Shred your own cheese, keep the heat low when the cheddar goes in, and mash a few potatoes for extra body.
 
From there, top it with bacon, ham, or a little spice and make it your own.
