This cheesy broccoli cauliflower casserole is the perfect hearty side dish, rich in flavor and easy to make. Fresh broccoli, cauliflower, cheese, and uncooked rice combine to make a hearty casserole topped with crumbled crackers.

Uniquely delicious, this recipe comes together quite quickly. And what I love about it is you use uncooked rice. No need to boil it to perfection. The rice cooks in the juices from the broccoli florets and cauliflower as they bake and become tender. That’s why this casserole has so much flavor!

This recipe comes from an old newspaper my grandma clipped at some point. And I’m so glad she did!

Recipe Tips
Make Ahead: Follow all the instructions, except do not top with the crackers. Refrigerate for up to 24 hours. When ready to bake, top with crumbled crackers and bake as directed.
Storage of Leftovers: Store any leftovers in an airtight container in the refrigerator for up to 3 days. You can store them individually sized in the freezer. The crackers will not be as crispy; otherwise, the recipe heats up fine.

Recipe FAQ
I would not recommend it. One of the keys to this recipe is that the vegetables release their juices while cooking, which helps to cook the rice. I can’t guarantee the same results with frozen broccoli and cauliflower.
I like to serve a protein like a roast or slow cooker ham. Because the casserole has rice, you have starch with vegetables, which makes it the perfect side dish!
Yes! I like the Mexican blend of shredded cheese I found at the grocery store. However, this recipe would work with straight cheddar, Gouda, or other types of cheese.

What other soup besides cream of celery?
I haven’t tested the recipe with any other soups. You could try cream of chicken, but I can’t guarantee the results. If you do try something else, let me know how it turns out!
