Cheesy Broccoli Rice Casserole

This Cheesy Broccoli Rice Casserole recipe is a staple at the holidays for our family. It was passed on from a family friend many years ago, and Mom has made it for the holidays ever since.

You may think the best part is the cheesy goodness, but in all honestly it could be the simplicity of the recipe. Nothing has to be precooked, and the broccoli goes in frozen. You mix everything together, pour it into a pan and bake.

The hardest part is truly melting the butter.Ask Barbara. She’s has had many butter explosions in the microwave. Take our advice, melt the butter in a small saucepan on the stove top over medium-high heat. It is the easiest method!

Broccoli Casserole with Cheese Whiz

Adding this side dish to your holiday line-up allows more time spent on desserts or main courses. This recipe is also a great way to get your kiddos to eat their veggies.

We like to use 2 (12 oz.) bags of frozen broccoli – one bag of broccoli cuts and one bag of broccoli florets. That way you get a good variety of stems and florets in the casserole. You could even substitute a bag of frozen cauliflower and broccoli which would be delicious.

The secret ingredient is Cheez Whiz. Cheez Whiz is the ultimate cheesy pleasure when it comes to casseroles.

What is Cheez Whiz?

Cheez Whiz is a processed cheese sauce that is kept on the shelf until opened. It’s similar to Velveeta in flavor but comes in a sauce instead of a log. Since it comes in sauce form, it does not need to be melted.

Cheez Whiz can be used as a simple dip for chips, or used for a cheesy sauce for baked potatoes and cooked cauliflower and broccoli. Another way to use Cheez Whiz is as an ingredient in cheesy casseroles.Thin out the Cheez Whiz with some melted butter for the perfect base for all sorts of casseroles.

What is a substitution for Cheez Whiz?

Velveeta (also called Cheese Melt) is a suitable substitute for Cheez Whiz; however, you will need to melt the Velveeta first to make it a sauce.
