Broccoli Cauliflower Casserole Loaded with Cheese

Broccoli Cauliflower Casserole, or rather a Cheesy Broccoli Cauliflower Rice Casserole, is the perfect hearty side dish for any chicken meal. Dump, Bake, and ready to serve a family recipe favorite in minutes flat. Plus this cauliflower casserole easily substitutes for a full meal; just add cooked protein! 

If you prefer to leave out the broccoli, try this Loaded Cauliflower Casserole or this Cauliflower Au Gratin Recipe instead – its SO good.

Broccoli Cauliflower Casserole

This broccoli cauliflower casserole, complete with cheesy broccoli, is the perfect hearty side dish. No protein needed (but totally Ok to add pre-cooked) this is nearly a full on main dish.

Ready to make some broccoli and cauliflower casserole? This deep dish way to eat your veggies and love them, is quickly made with only frozen broccoli and frozen cauliflower. A perfect side dish for chicken and fantastic for holiday meals like Thanksgiving and Christmas, its a catch all dish that may actually get your kids to eat! You can even serve it right next to my original broccoli cheese casserole with ritz crackers for another side dish ready to fill up your family. 

Cheesy Broccoli Cauliflower Rice Casserole

Unfortunately this cauliflower casserole is not without carbs. It’s hard to get anything with rice in the “low carb” or “keto” category, but if you want to try to alter and still need the filler, try Rutabaga Rice or make it extra cauliflower-y and add cauliflower rice! 

Cauliflower rice isnt actually rice, its just tiny pieces of cauliflower chopped up so much that it can fool you into being rice. Kinda. Its still pretty good and is in the frozen department. 

Serves 6

• 1 package frozen broccoli florets
• 1 package frozen cauliflower
• 2 cups cooked white rice
• 3 tablespoons butter
• 3 tablespoons corn starch
• 2 cups milk
• 2 cups shredded cheddar jack cheese
• ½ teaspoon salt
• ½ teaspoon paprika
• ½ teaspoon garlic powder
• ½ teaspoon pepper

Can you freeze broccoli cauliflower casserole?

Listen I think you can freeze just about anything when it comes down to it but I don’t tend to like frozen food. Because you make this casserole with already frozen broccoli and cauliflower, its best to make and eat, then make, freeze, and eat.

Can you use a different type of Cheese in your Casserole?

Absolutely! In fact, changing out cheese can alter the taste to your liking. When it comes to casseroles, I like cheddar jack, cheddar, Colby jack and Monterrey jack cheeses. You can also try something richer like Gouda if that is your wheelhouse.

Casseroles on the Go

Casseroles are the perfect side dish to take to a party or family get together. Make sure you have a casserole tote to keep this one warm and ready to eat. I also love to use one with my Chicken Casserole with Ritz topping.
