Tips and tricks

Here are some helpful suggestions for preparing and storing this easy broccoli casserole:

Fresh broccoli chopped into large pieces is best for this recipe If you can’t get fresh broccoli, frozen will be fine.
You can use your favorite store bought sauce, or my homemade Alfredo sauce, sharp white cheese sauce, or creamy cheese sauce.
If you prefer softer broccoli in the casserole, cover and steam for 2-3 minutes before adding the cream.
Mix in extra veggies like peppers, green beans, asparagus, or greens for extra flavor and nutrients.
Prepare this ahead of time by cooking the veggies and making the sauce (if you’re making homemade). You can even mix it up and put it in the baking dish. Wait to cover with the topping until you’re ready to bake.
I used a square baking dish for this recipe. Most casserole dishes will work, but you may need to adjust baking time depending on the depth.
Stored in an airtight container in the refrigerator, leftovers will keep for up to 4 days. Reheating in the oven is best for the crispiness, but microwaving would suffice.

Common Questions

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

Yes, you’ll definitely want to precook the broccoli a bit. I suggest sautéing for about 5 minutes. If you want it softer, cover and cook for an additional 2-3 minutes.

Can you freeze broccoli and cheese casserole?

You can, but if you do it’s best to freeze before you bake. Store it in an airtight container for up to 3 months. Just make sure to defrost before baking.

How long do you cook a casserole that has been refrigerated?

If you’ve refrigerated the casserole, you’ll want to cook for a little bit longer. If you used the recommended square baking dish it should take 30-40 minutes to heat all the way through.
