Key Ingredients

This Cheesy Broccoli Rice Casserole recipe only requires a few ingredients, including: fresh broccoli (cut into bite-sized pieces), white rice (cooked), unsalted butter, all-purpose flour, whole milk, mustard powder, paprika, onion powder, garlic powder, sharp cheddar cheese, grated Parmesan cheese, cream cheese (softened to room temperature), salt, and freshly cracked black pepper.

You can also swap brown rice for the white rice, if desired, as well as milk of your choice or even half-and-half for the whole milk. Quinoa or cauliflower rice would work as a low carb healthy swap for the cooked rice!

How To Blanch Broccoli

The trick to preventing your broccoli from turning to mush during the cooking process — especially if you’re planning to bake it — is to blanch it.

Blanching is a culinary technique in which vegetables, especially green vegetables like broccoli or asparagus, are flash boiled for just a couple minutes, then submerged in an ice bath to halt the cooking process in its tracks. This ensures that it’s cooked enough to break down cell walls of the vegetables molecular structure, but not to much so that it’s fully cooked; similar to browning meat.

Blanching is often practiced before freezing vegetables so they don’t succumb to freezer burn or spoil, but it’s also useful in this Broccoli Rice Casserole recipe because it allows the broccoli to cook enough to easily bite into, but not so much that it melts into the rest of the dish.

Variations

  • Add more vegetables: Diced carrots, peas, or mushrooms would be amazing in this. You could also swap the broccoli for cauliflower florets.
  • Add some crunch: Crumbled up ritz crackers or toasted panko can be added to the top of the casserole along with the cheddar cheese.
  • Use your favorite type of cheese: I love using extra sharp cheddar cheese in this recipe however use what you have on hand. Monetary jack cheese, Colby swiss or gouda would all be great. 
  • Substitute frozen broccoli: I recommend using fresh broccoli in this easy broccoli rice casserole. However if you would like to use frozen broccoli instead simply thaw the broccoli first before tossing it with the rice and cheese sauce. I also like to make sure I drain the broccoli after it’s thawed to remove any excess moisture which could make the casserole watery.
  • Chicken broccoli and rice casserole: Make this a meal and add in your favorite protein. Leftover rotisserie chicken or my instant pot shredded chicken would both work great.

Can Broccoli Rice Casserole be made ahead of time?

I love making this casserole during the holidays because it is so easy to make ahead of time. Simply make the recipe as directed and store it unbaked covered in the refrigerator until you are ready to bake! Allow it to come to room temperature while the oven preheats then bake as directed.

  • Store leftover broccoli cheese rice casserole in an airtight container in the fridge for up to 5 days.
  • Freeze the cooled and cooked casserole in an airtight, freezer-safe container or plastic bag for up to 3 months. To reheat from frozen simply defrost overnight in the refrigerator and allow it to come to room temperature while the oven preheats. Bake as directed.
  • Reheat this casserole in the microwave with some water or chicken broth for 3-5 minutes, or in the oven until warmed through and bubbling around the edges.
