Ingredients
Cooked broccoli – This is a great way to use leftover broccoli. You can also use roasted broccoli, Broiled Broccoli or cook some fresh or frozen broccoli just to make the casserole.
Sour cream – Adds creaminess to the casserole dish.
Mayonnaise – Great for adding a tiny bit of flavor and creaminess.
Minced onion – Fun flavor and a simple addition to change the taste.
Garlic powder – Great for adding flavor.
Salt – For taste. You can use more or less according to your preference.
Pepper – Add black pepper to your taste as well.
Shredded Cheddar Cheese – You can use any type of cheese that you’d like but we love a good broccoli cheddar casserole made with sharp cheddar cheese.
Bacon crumbles – You can cook bacon and crumble them, or buy already crumbled bacon.
How to make Leftover Broccoli Casserole
Step One: Preheat the oven to 350 degrees. Spray an 8X8 pan with nonstick cooking spray.
Step Two: Mix the seasonings with the sour cream, mayo, half the cheese, and half the bacon.
Step Three: Fold in the cooked broccoli and then spread the mixture out into the casserole dish. Top with the rest of the bacon and cheese.
Step Four: Put the dish in the oven and bake until hot for about 20 minutes.
Variations
Add rice – If you want to make this dish even heartier, add white rice or brown rice. Rice is a great addition to this cheesy broccoli casserole dish. You can use leftover rice as well. For a keto version just add cauliflower rice.
Add cream of mushroom soup – If you want to opt out of using the mayo or sour cream, you can add cream of mushroom soup or cream of chicken soup. I prefer to make this homemade version. You could also add a little bit of cream cheese as well.
Top with cheese sauce – This is pretty cheesy but if you want extra sauce check out my recipe for keto cheese sauce. Add the creamy sauce to add to the top of this dish.
Add meat – Chicken breasts and pork chops that are cooked and leftover can be a great addition to make this a complete meal. You can also add ground beef, leftover ham, or even shredded pork as well. Delicious recipes like this are versatile.
Common Questions
What are other toppings that I can add to this easy broccoli casserole recipe?
Adding toppings to the prepared baking dish is a great idea. You can add bread crumbs, corn flakes, different types of shredded cheese, bacon bits, and anything else that you want. All options would be a perfect addition. Just be aware that if you are one of my low carb keto readers some of these additions would have additional net carbs and may not be keto.
Can I add meat to this broccoli casserole recipe?
You can! Using leftover chicken in this dish is a great recipe, too. You just need to add the already-cooked chicken with the rest of the ingredients and cook it in the oven just like the recipe card says.
Buying a rotisserie chicken at the grocery store and adding it would be a great option, too. That way, you can create cheesy chicken broccoli rice casserole in a jiffy. This shouldn’t really affect the cooking time since the chicken is already cooked.
What if I don’t have any leftover broccoli to use?
You can easily use fresh broccoli florets and cook them to be tender broccoli for this dish. You can also use frozen broccoli as well.
How do I store leftovers?
If you have leftovers of this simple casserole, storing them is a breeze! You just need to let the casserole cool down all the way, and then store the leftovers in the fridge in an airtight container.
When you are ready to eat the leftovers, you just need to scoop out your portion and reheat it in the oven or microwave. It’s as simple as that!

Great way to dress up broccoli! I used frozen broccoli, thawed and patted dry, subbed yogurt for the sour cream, and Canadian bacon for the bacon crumbles. The sauce was great and wasn’t too cheesy. Finally, a recipe that had a nice amount of cheese instead of drowning a dish like I usually find in recipes. It was a very filling side dish. Thanks for a great recipe!
I made this with 2 c broccoli florets and 2 c. rotisserie chicken. I was surprised how seemingly little ‘sauce’ there was, so I added a tad more mayo. (Is it supposed to be that way?) Aside from that, I followed the recipe. I had a small portion last night, but am enjoying leftovers now, microwaved. I think I’m enjoying it more tonight than last! Thanks!
To make it saucier you can add 1/4 cup of heavy cream or half and half.
