Easy Creamy Potato Broccoli Cheddar Soup
This easy creamy potato broccoli cheddar soup is rich, comforting and packed with tender potatoes, fresh broccoli and plenty of melted cheddar cheese. The potatoes naturally thicken the soup as they cook, giving it a hearty, creamy texture without making it feel too heavy. A sprinkle of pumpkin seeds and black nigella seeds on top adds a little crunch and a subtle savoury flavour that works surprisingly well with the cheese.

It’s the kind of homemade broccoli cheddar soup that works perfectly for a cozy lunch or an easy weeknight dinner, especially when the weather starts to cool down. Serve it with crusty bread or a simple sandwich and you have an easy, satisfying meal that doesn’t take much effort to put together.
A Cozy Bowl of Potato Broccoli Cheddar Soup
This creamy potato broccoli cheddar soup is thick, comforting and full of simple ingredients that work really well together. Tender potatoes give the soup its hearty texture, while fresh broccoli and sharp cheddar add plenty of flavour. I like leaving some of the potato pieces whole instead of blending everything completely smooth. It makes the soup feel more homemade.

Why This Soup Just Works
The potatoes naturally help thicken the broth, so you get a creamy soup without needing a complicated roux. Sharp cheddar melts into the soup and gives it that rich, savoury flavour you expect from a good broccoli cheddar soup. The broccoli adds freshness and a little texture, and the pumpkin seeds and black nigella seeds on top give each bowl a nice bit of crunch.
It’s filling too. A bowl of this with some crusty bread is often enough for dinner.

Perfect for Cool Days and Easy Dinners
This easy potato broccoli cheddar soup is especially good for fall and winter dinners, but I would happily make it any time I want something warm and comforting. It works well for a casual family dinner, weekend lunch or an easy soup-and-sandwich meal.
It also reheats nicely, which makes it handy for leftovers the next day. Sometimes soup is even better after the flavours have had a little more time together.
Tips for the Best Potato Broccoli Cheddar Soup
Use Yukon Gold potatoes if you can. They become naturally creamy as they cook and give this potato broccoli cheddar soup a rich texture without turning gluey.
Cut the potatoes into fairly small, even pieces. They cook faster and more evenly. I usually check them with a fork before blending—if the fork slides in easily, they’re ready.
Don’t blend the entire soup. Blending only part of the potatoes gives you a creamy base while still leaving some tender potato pieces throughout. I think the texture is much better this way.
Add the broccoli near the end. Broccoli cooks quickly, and adding it too early can make it very soft and dull in colour. About 5–7 minutes is usually enough for small florets.
Shred your own cheddar cheese. Pre-shredded cheese often contains anti-caking ingredients that can keep it from melting as smoothly. Freshly shredded sharp cheddar gives the soup a creamier finish.
Keep the heat low when adding the cheese. This is important. If the soup is boiling, the cheddar can become grainy or separate. Stir it in gradually over low heat.
Use sharp cheddar for more flavour. A good sharp orange cheddar gives this broccoli cheddar potato soupboth its rich flavour and its warm golden colour.
Add the cream after the potatoes are cooked. There’s no need to simmer the cream for a long time. Stirring it in near the end keeps the soup smooth and creamy.
Thin it only if needed. Potato soup thickens as it sits, so keep a little extra chicken broth nearby. A small splash is usually all it takes to loosen leftovers.
Save the toppings until serving. Pumpkin seeds and black nigella seeds add a nice little crunch, but they soften if they sit in the soup too long.
Taste before adding extra salt. Chicken broth and cheddar can both be fairly salty, so I like to wait until the cheese has melted before making the final seasoning adjustment.
Easy Variations for Potato Broccoli Cheddar Soup
Make it extra cheesy. Add another ½ cup of sharp cheddar for a richer, more indulgent broccoli cheddar potato soup. Just add the cheese gradually over low heat so it stays smooth.
Use cauliflower with the broccoli. Replace half the broccoli with small cauliflower florets for an easy broccoli cauliflower cheddar soup. The cauliflower blends into the creamy potato base really well.
Add crispy bacon. A little crumbled bacon on top turns this into an even heartier potato broccoli cheddar soup. I would add it just before serving so it stays crisp.
Try white cheddar. White cheddar gives the soup a slightly different look but still delivers plenty of sharp cheese flavour. It works especially well if you want a paler, creamier soup.
Add a little heat. Stir in a pinch of red pepper flakes or cayenne for a mild kick. You don’t need much—the cheddar and potato should still be the main flavours.
Make it vegetarian. Simply use vegetable broth instead of chicken broth. The potatoes, broccoli and cheddar still give the soup plenty of flavour.
Add corn for a little sweetness. A cup of corn works surprisingly well in this creamy potato broccoli soup and adds more texture too. Frozen corn can go straight into the pot near the end.
Use different potatoes. Russet potatoes will make the soup thicker and a little more rustic, while Yukon Gold potatoes give it a smoother, naturally buttery texture.
Make it lighter. Replace the heavy cream with half-and-half or whole milk. The soup will be slightly less rich, but the potatoes still keep it nicely creamy.
Change up the toppings. Pumpkin seeds and black nigella seeds give this soup a really nice finish, but toasted sunflower seeds, extra shredded cheddar or chopped green onions would also work well. Sometimes changing the topping is enough to make leftovers feel like a different meal.
How to Store and Reheat Potato Broccoli Cheddar Soup
Let the soup cool before storing. Once your potato broccoli cheddar soup has cooled to room temperature, transfer it to an airtight container. I wouldn’t leave it sitting out for more than about 2 hours.
Refrigerate for up to 3–4 days. This creamy broccoli cheddar potato soup keeps well in the refrigerator and makes an easy lunch the next day.
Expect it to thicken overnight. Potatoes continue absorbing liquid as the soup sits, so leftovers will usually be thicker. That’s normal. Stir in a splash of chicken broth, milk or cream when reheating if needed.
Reheat gently on the stovetop. Warm the soup over low to medium-low heat, stirring often. Try not to let it boil because high heat can cause the cheddar and cream to separate.
Microwave in shorter intervals. Reheat individual portions for about 60 seconds at a time, stirring between each interval. This helps the creamy potato broccoli soup heat evenly without overheating the cheese.
Store toppings separately. Keep pumpkin seeds and black nigella seeds in a separate container and add them after reheating. They stay much crunchier that way.
Freezing isn’t my first choice. You can freeze this soup, but dairy-based soups with potatoes sometimes change texture after thawing. The potatoes can become slightly grainy and the cream may separate.
If you do freeze it, use an airtight freezer-safe container and freeze for up to 2 months. Thaw overnight in the refrigerator, then reheat slowly while stirring well.
A little extra cheddar can revive leftovers. If the reheated soup tastes a bit less rich, stir in a small handful of freshly shredded cheddar at the end. It brings back that fresh broccoli cheddar soup flavour nicely.
Easy Potato Broccoli Cheddar Soup
Equipment
- Large soup pot or Dutch oven
- Cutting board
- Chef’s knife
- Vegetable peeler
- Measuring cups and spoons
- Wooden spoon or silicone spatula
- Immersion blender
- Cheese grater
- Ladle
- Soup bowls
Ingredients
- 2 tablespoons butter
- 1 yellow onion medium sized finely diced
- 3 cloves garlic minced
- 4 Yukon Gold potatoes medium sized, peeled and cut into small cubes
- 4 cups chicken broth
- ½ teaspoon paprika
- ½ teaspoon salt or to taste
- ¼ teaspoon ground black pepper
- 2½ cups broccoli florets cut into small pieces
- 1 cup heavy cream or half-and-half
- 2 cups cheddar cheese freshly shredded sharp orange cheddar
- ½ cup pumpkin seeds for serving
- 1-2 teaspoons black nigella seeds for serving
Instructions
Sauté the onion and garlic.
- Melt the butter in a large soup pot over medium heat. Add the diced onion and cook for 4–5 minutes, stirring occasionally, until softened. Add the garlic and cook for another 30 seconds.
Cook the potatoes.
- Add the diced potatoes, chicken broth, paprika, salt and black pepper. Stir well and bring the soup to a gentle boil.
Simmer until tender.
- Reduce the heat to medium-low, cover partially and simmer for about 15–18 minutes, or until the potatoes are very tender when pierced with a fork.
Blend part of the soup.
- Use an immersion blender to blend roughly half of the potatoes directly in the pot. Don't blend everything. Leaving some small potato pieces gives this creamy potato broccoli soup a much nicer homemade texture.
Add the broccoli.
- Stir in the broccoli florets and simmer for another 5–7 minutes, until the broccoli is tender but still has a little bite. Smaller florets cook quickly, so keep an eye on them.
Add the cream.
- Reduce the heat to low and stir in the heavy cream. Heat gently for 2–3 minutes without bringing the soup back to a boil.
Melt in the cheddar.
- Add the shredded cheddar a handful at a time, stirring after each addition until completely melted. Keeping the heat low helps produce a smooth and creamy broccoli cheddar soup rather than a grainy cheese sauce.
Adjust the consistency.
- If the soup is thicker than you like, stir in a small splash of additional chicken broth. Taste and adjust the salt and pepper.
Serve.
- Ladle the Potato Broccoli Cheddar Soup into bowls and top with pumpkin seeds, a few black nigella seeds and additional shredded cheddar if desired.
Notes
- Yukon Gold potatoes work especially well because they become creamy while still holding some texture.
- Freshly shredded cheddar melts more smoothly than packaged pre-shredded cheese.
- Use sharp cheddar cheese for the strongest flavour and a beautiful golden colour.
- Don't boil the soup after adding the cream and cheddar. High heat can cause the cheese to separate.
- Cut the broccoli into small florets so you get a little broccoli in almost every spoonful.
- The soup naturally thickens as it sits. Add a splash of broth when reheating if necessary.
- Sprinkle the pumpkin and black nigella seeds over the soup just before serving so they stay crunchy.
