Ingredients and Substitutions
- Butter – Butter is going to give you a better flavor and texture compared to olive oil. Stick with unsalted so that you can season this broccoli cheese bake yourself.
- Frozen Broccoli – You could use frozen or fresh broccoli for this recipe but I prefer the ease of frozen broccoli florets. They end up perfectly tender and delicious.
- Onion – I like to use yellow onion for this casserole recipe but white onion will work just fine as well.
- Garlic – I prefer freshly sliced garlic for this recipe. If you don’t have any on hand, you can add a 1/4-1/2 teaspoon of garlic powder or more to taste in its place.
- Flour – Stick with all-purpose flour for this broccoli casserole recipe. It will give your cheese sauce the best texture.
- Whole Milk – Whole milk gives the cheese sauce in this recipe the perfect consistency. You could sub half and half if that’s all you’ve got, but your sauce will likely be a bit thicker so you may need to add a bit more.
- Sharp Cheddar – You can use your favorite melty cheese for the cheese sauce in this recipe. I like to use sharp cheddar but I’ve also tried with white sharp cheddar, fontina, and havarti and all were delicious!
- Potato Chips – Classic Ruffles are my favorite chip for this dish, but switch it up to suit your family’s taste! Try cheddar sour cream or even jalapeno cheddar chips for a different flavor combo. You can also use Ritz crackers in place of the potato chips.

Saute onion and garlic in butter. Add flour.

Let cool just a few minutes and then dig in and enjoy!
Making the Perfect Cheese Sauce
This broccoli cheese casserole has a deliciously creamy cheese sauce and while it’s super simple to make, if you step away from the stove while you’re cooking – even just for a minute – you may need to troubleshoot a bit. Here are my tips for making sure that cheese sauce is perfectly creamy and dreamy every single time!
- You’re looking for a cheese sauce that’s similar to a creamy queso dip. It should coat the back of a spoon and cling to it. It shouldn’t be dripping off the spoon immediately – it should be thick and creamy.
- If the cheese sauce isn’t getting creamy, warm it over low heat, stirring frequently, for a couple minutes until it thickens a bit more. But be sure that the sauce doesn’t come to a simmer because if it gets too warm, the cheese will separate from the sauce and you’ll end up with a grainy texture.
- If the cheese sauce is too thick, trying adding a splash or two of milk to loosen it up.
Tip
- Once the frozen broccoli comes in contact with the warm cheese sauce, it’s going to cause the cheese sauce to thicken and seize up a bit. This is normal. Just combine the broccoli with the cheese sauce very well so that each piece of broccoli is well coated. When the casserole bakes in the oven, the cheese sauce will loosen up and get perfectly creamy again.
FAQ
No! The best part is that you can throw frozen or fresh broccoli right into the creamy cheese sauce and then bake it all together in the oven! Broccoli cooks quite quickly so if you cook it before hand it will end up being overcooked once the casserole is baked.
Yes, you can! Frozen is convenient because you don’t have to chop it up and you can keep it in the freezer until you’re ready to use it. But fresh broccoli will work just as well in this recipe!
This broccoli cheese casserole relies on a quick mixture of flour and butter to thicken the creamy sauce. The best part about this recipe is that the cheese sauce cooks before you bake everything together so you can control exactly how thick and creamy it gets!

Instructions
- Melt butter in a large sauté pan and heat over medium heat.

Kylie, This is SOOOO good! The only recommendation I have is to double the cheese sauce and save 1/2 of it for dipping chips or raw vegetables into. Yum!
That is a brilliant idea! Extra cheese sauce is always a great idea!!
