This Cheesy Broccoli Rice Casserole has been a family favorite casserole for a long time.  This is my mother’s recipe and it’s the best that I’ve ever tasted.  It’s extra creamy and cheesy and it’s topped with lots of crispy fried onion rings! It’s the perfect side dish for any family gathering, potluck, or holiday meal.

T his recipe is from my cookbook Deliciously Southern.  It’s one of my favorites and one of the most popular recipes in the cookbook. It’s super easy to make and there is never a morel left. It’s just plain good comfort food.

You can add cooked chicken to this and have a whole meal.  It also freezes well so you can double the recipe and freeze one.  This works great for busy families on the go.

What you’ll need to make Cheesy Broccoli Rice Casserole: ( Be sure to see the full printable recipe at the bottom of this post)

  • Fresh broccoli florets 
  • Salt & pepper 
  • Butter
  • Sweet yellow onion 
  • White rice
  • Cheez Whiz
  • Cream of mushroom soup 
  • Freshly grated cheddar cheese 
  • French fried onion rings

Tips on how to make Cheesy Broccoli Rice Casserole:

  1. Don’t overcook your broccoli. I used to use frozen broccoli in this casserole, but now I just recommend using fresh broccoli. Fresh broccoli tastes so much better in this casserole and it holds up better too. Cut the broccoli up into small pieces. I barely blanched it because it will continue to cook when you bake it. I place the broccoli in hot water for only about 12 seconds then run cold water over it to stop the cooking process. This also keeps the broccoli a beautiful green color. (Note: If you do use frozen broccoli, don’t blanch it because it has already been blanched. Just make sure that you drain the broccoli well.
  2. Be sure to use a sweet onion.  Using a sweet onion is very important to the best-tasting casserole.  I live in Georgia so if possible I love to use sweet Vidalia onions if they are in season. The chopped onion is saluted in butter until it’s just before it’s translucent.  There again I don’t want to overcook the onion because it will cook while the casserole is baking.  You want the onion to still be a little crunchy. 
  3. Don’t overcook the rice: Cook the rice according to the package directions.  If the rice is overcooked, your casserole will be soggy.  What you want your rice to be nice and fluffy!
  4. Use Cheese Whiz: A jar of delicious Cheese Whiz is the secret ingredient to this casserole.  It gives this casserole a deliciously cheesy, rich creamy taste!  You can usually find it on the grocery store aisle where the macaroni noodles are or in the snack food section where the onion dips are.
  5. Use Freshly grated cheese: Believe me, taking the time to grated the cheese will make all the difference in the world.  I promise!  Freshly grated cheese melts better and is definitely more creamy and better tasting. It’s ready to go in the oven.  After baking uncovered for about 20 minutes, you add a layer of cheese on top and continue baking until the cheese is completely melted.
  6. Use Campbell’s Soup brand of cream of mushroom soup:  I’ve used an off-brand before and Campbell is the best.
  7. Top it off with a crunchy topping:  I love to put crispy French fried onion rings on top.  If you don’t like French fried onion rings, buttery Ritz crackers are delicious too.

I know that you are going to enjoy this recipe for many happy occasions and holidays. For more delicious Southern recipes, be sure to check out my cookbook Deliciously Southern.

Do ahead/freeze tip:  You can make the casserole up two or three days ahead. Store in the refrigerator and it will be ready to bake.
