Ingredient notes and substitutions:

Ingredients for broccoli cheese casserole include broccoli florets, shredded cheese, and a bowl of sour cream.

Fresh broccoli florets or frozen broccoli – brings a unique flavor profile to this traditional side dish, and either one works in this recipe. Tender broccoli, along with cauliflower and cabbage, is considered a cruciferous vegetable high in fiber, vitamins, and minerals.
Sour cream – provides a creamy base and tangy deliciousness.
Mayonnaise – another thick and creamy base component- adds sweetness and tangy flavor.
Cream of mushroom condensed soup – has been used as the base of hundreds of casseroles over the years and is an essential component of this creamy casserole recipe.
Sharp cheddar cheese – it couldn’t be a broccoli cheddar casserole without cheese, and the melted sharp cheddar cheese adds cheesy goodness and another dimension to the sauce.
Garlic powder, Kosher salt, ground black pepper – these seasonings all come together to enhance the other ingredients’ flavors.
Ritz crackers – the crispy topping made from these buttery crackers is one of the best parts of this casserole.
Unsalted butter – is combined with the cracker crumbs to make the topping rich and buttery!

Complete measurements are listed in the recipe below.

Want to change things up a bit?

Feel free to add a cup of cooked chopped chicken or two cups of cooked brown rice, white rice, or orzo to make a cheesy broccoli rice casserole.
You can also replace half of the broccoli with cauliflower or top the casserole with pork chops before baking.
Additionally, feel free to sprinkle parmesan cheese over the top before baking.

Make it ahead:

To make this casserole ahead of time, assemble the dish, but do not add the cracker topping. Cover and refrigerate for up to 24 hours. When ready to bake it, add the topping and bake as directed.

To freeze, make the casserole as directed, but do not bake it. Cover tightly with plastic wrap and then aluminum foil. It can be stored in the freezer for up to three months. Allow the casserole to thaw overnight in the refrigerator before baking it.

If it is cold right out of the fridge, let it come to room temperature first, or you may need to add 10-15 minutes to the total baking time.

How to store and reheat leftovers:

To store – Let the casserole come to room temperature. Transfer it to an airtight container or cover the casserole dish with plastic wrap or aluminum foil. It can be safely stored in the fridge for about 3-4 days or frozen in the freezer for 2-3 months. Be sure to defrost the leftovers in the refrigerator overnight before reheating.
To reheat in the oven – Preheat the oven to 350°F. Transfer the casserole to an oven-safe dish if it isn’t already in one. Cover the dish with aluminum foil to help retain moisture. Bake for 15-20 minutes or until the casserole is heated through. The time might vary depending on the quantity and thickness of the leftovers.
To reheat in the microwave – place a casserole serving on a microwave-safe dish. Cover with a microwave-safe lid or microwave-safe plastic wrap. Leave a small corner open to let steam escape. Heat on medium power for 1-2 minutes, then check. If it’s not thoroughly reheated, continue in 30-second increments.

Recipe FAQs:

Is it better to use fresh or frozen broccoli in this recipe?

You can use three stalks of fresh broccoli or one 15-ounce bag of frozen. Either works perfectly in this side dish.

Do you have to cook fresh broccoli before putting it in the casserole?

I don’t usually blanch fresh broccoli first because I like it crisp. However, if you prefer your broccoli a little softer, you will want to blanch it first.

How to blanch it?

To blanch fresh broccoli, place it in a bowl, add a tablespoon of water, cover with a plate and steam it in the microwave for about two minutes.

Do you have to cook frozen broccoli before putting it in the casserole?

No, frozen broccoli has already been blanched and does not need to be cooked first.

Do you put eggs in broccoli casserole?

Most recipes for broccoli cheese casserole do not call for eggs as an ingredient, and this one is no exception. Recipes that call for adding eggs tend to be more breakfast-oriented such as my Mushroom and Broccoli Frittata or Broccoli Cheese Bake.

Expert tips and tricks:

If you don’t have any Ritz crackers, you can use any butter crackers or crush croutons and use them instead. You can substitute crushed club crackers, panko bread crumbs, or fried onion rings. To make it low-carb, substitute crushed pork skins for the crackers.
You can also substitute cream of chicken soup or cream of celery soup in a pinch.
When testing your broccoli to see if it is done, try a piece of the stalk and not a floret, which will cook much faster.
If you prefer soft broccoli, you might also want to leave the casserole in the oven for an additional five minutes or until it is a consistency you like.
To change things up a bit, if you don’t have cheddar you can substitute gruyere, fontina, Havarti, a Mexican blend, an Italian blend of cheeses, Velveeta, or even Cheez Whiz.
If you are using frozen broccoli, you do not have to thaw it first.
This recipe as written makes about six servings. If you need to feed more people, you can double the recipe and use a 9×12 inch baking dish.
