What You Need
Serves 4 people
For the Broccoli
- 4 cups fresh broccoli florets
- 1 cup water
For the Cheese Sauce
- 1 tablespoon butter
- 1 cup milk
- 1 tablespoon cornstarch
- 1 cup sharp cheddar cheese, freshly shredded
- 2 tablespoons Parmesan cheese, grated
- ½ teaspoon garlic powder
- Salt and black pepper to taste
How To Make It

Step 1 — Steam the broccoli
Wash the broccoli florets and place them in a large skillet or saucepan.
Add the water and bring it to a gentle simmer over medium heat. Cover the pan and steam the broccoli for 4 to 5 minutes until tender-crisp.
Transfer the broccoli to a serving bowl and keep warm.
Step 2 — Prepare the sauce base
In a small bowl, whisk together the milk and cornstarch until completely smooth.
Using the same pan, melt the butter over medium heat. Pour in the milk mixture and whisk continuously.
After a few minutes, the mixture will begin to thicken.
Step 3 — Add the cheese
Reduce the heat to low.
Gradually add the shredded cheddar cheese and Parmesan cheese while stirring constantly.
Continue stirring until the cheese melts completely and the sauce becomes smooth, creamy, and glossy.
Step 4 — Season the sauce
Add garlic powder, salt, and black pepper.
Taste and adjust the seasonings if needed.
The sauce should be rich, creamy, and packed with cheesy flavor.
Step 5 — Serve immediately
Pour the warm cheese sauce over the steamed broccoli.
Gently toss until every floret is coated in the creamy sauce.
Serve immediately while hot.
Tips For The Best Results
Shred your own cheese
Pre-shredded cheese often contains anti-caking agents that can make the sauce less smooth. Freshly shredded cheese melts much better.
Don’t boil the sauce
Once the cheese is added, keep the heat low. High heat can cause the sauce to separate or become grainy.
Steam, don’t overcook
Broccoli should remain slightly firm. Overcooked broccoli can become mushy and lose its bright green color.
Make extra sauce
This cheese sauce is delicious on cauliflower, baked potatoes, carrots, and even pasta.
Easy Variations To Try

Add bacon
Sprinkle crispy bacon pieces over the finished dish for extra flavor and crunch.
Make it spicy
Add a pinch of cayenne pepper or red pepper flakes for a little heat.
Use different cheeses
Try Monterey Jack, Gouda, Colby Jack, or a blend of cheeses for a different flavor profile.
Add more vegetables
Cauliflower, carrots, and Brussels sprouts all pair beautifully with this cheese sauce.
Common Questions
Can I use frozen broccoli?
Yes. Frozen broccoli works well. Steam it according to package directions before adding the cheese sauce.
How do I store leftovers?
Store the broccoli and cheese sauce separately in airtight containers in the refrigerator for up to 3 days.
Can I make the sauce ahead of time?
Yes. Reheat it gently over low heat while stirring. Add a splash of milk if it becomes too thick.
Why is my cheese sauce grainy?
This usually happens when the heat is too high. Always melt cheese slowly over low heat for the smoothest results.
What other vegetables can I serve with this sauce?
Cauliflower, carrots, asparagus, green beans, and roasted potatoes all taste great with this cheese sauce.
