I love how the broccoli and cauliflower give the dish a hearty vegetable base while the rice makes it more filling. It is simple enough for a weeknight dinner, but comforting enough to serve for holidays, potlucks, or Sunday family meals.

What Ingredients Are in Broccoli and Cauliflower Casserole?
This casserole uses simple ingredients, but each one plays an important role. The broccoli and cauliflower bring freshness and texture, the rice adds body, and the cheese mixture makes the whole dish creamy and comforting.
Ingredients
½ cup uncooked white rice
10 ounces broccoli florets
10 ounces cauliflower florets
½ cup butter
1 onion, chopped
1 pound processed cheese food, cubed
1 can condensed cream of chicken soup, 10.75 ounces
5 ⅜ fluid ounces milk
1 ½ cups crushed buttery round crackers
When choosing your vegetables, fresh broccoli and cauliflower work beautifully because they hold their texture well after baking. You want them cooked until crunchy-tender before they go into the casserole, so they do not become too soft in the oven.
The processed cheese gives this dish its signature creamy, melty texture. It blends smoothly with the cream of chicken soup and milk, creating a rich sauce that coats the rice and vegetables evenly.
And don’t skip the cracker topping. The crushed buttery crackers bake into a crisp, golden layer that makes every serving feel extra satisfying.
How to Make Broccoli and Cauliflower Casserole
Making this broccoli and cauliflower casserole is simple, but the layers of flavor make it taste like something special.
Cook the Rice
Start by bringing water to a boil in a saucepan. Add the uncooked white rice and stir. Reduce the heat, cover the pan, and let the rice simmer for about 20 minutes. Once it is cooked, drain it if needed and set it aside.
The rice helps make the casserole hearty without overpowering the vegetables. It also soaks up the creamy cheese sauce, which makes every bite rich and flavorful.
Cook the Broccoli and Cauliflower
Next, simmer the broccoli and cauliflower florets in water for about 10 minutes, or until they are crunchy-tender. You want them softened but not mushy, since they will continue cooking in the oven.
While the vegetables cook, preheat the oven to 350 degrees F, or 175 degrees C.
Make the Creamy Cheese Mixture
In a large saucepan, melt the butter and sauté the chopped onion until it becomes fragrant and slightly softened. Stir in the cooked cauliflower, broccoli, and rice. Mix everything until the vegetables and rice are coated in the buttery onion mixture.
Add the cubed processed cheese, condensed cream of chicken soup, and milk. Stir until the mixture becomes creamy and evenly combined. The cheese will melt into the soup and milk, creating a thick, savory sauce.
Assemble and Bake
Transfer the entire mixture to a 9×13-inch baking dish. Spread it out evenly, then sprinkle the crushed buttery crackers over the top.
Bake the casserole in the preheated oven for 30 minutes, or until the topping is golden and the filling is hot and bubbly.
Let it rest for a few minutes before serving so the creamy filling can settle slightly.

Broccoli and Cauliflower Casserole Tips
For the best texture, avoid overcooking the broccoli and cauliflower before baking. They should still have a little bite when you add them to the casserole.
If you want a richer topping, you can toss the crushed crackers with a little melted butter before sprinkling them over the dish. This gives the top an even more golden, crisp finish.
This casserole is best served warm from the oven, but leftovers reheat well. Store them in an airtight container in the refrigerator and warm individual portions in the microwave or oven.
Broccoli and Cauliflower Casserole Substitutions and Variations
One of the best things about this casserole is how easy it is to adjust.
Cheese Options
Processed cheese melts smoothly, but you can mix in shredded cheddar for a sharper flavor. A combination of processed cheese and cheddar gives the casserole both creaminess and extra cheesy depth.
Soup Options
Cream of chicken soup gives the casserole a savory flavor, but cream of mushroom or cream of celery can also work if you want a slightly different taste.
Topping Options
Buttery round crackers are classic, but you can also use crushed cornflakes, panko breadcrumbs, or seasoned crackers for a different crunch.
Vegetable Add-Ins
You can add cooked carrots, peas, mushrooms, or diced bell peppers if you want to stretch the casserole or add more color.
