Looking for a few more ways you could make this cheese and vegetable casserole?

Feel free to throw in some other vegetables, or replace the broccoli entirely! Cauliflower, mushrooms, asparagus, onions, and bell peppers are all great low-carb vegetables that work wonderfully in this rich, cheesy bake.

You can also play around with the herbs and spices depending on your tastes. Simply add them to the cheese sauce while it simmers on the stove.

For example, you could add in some cayenne pepper or chili flakes to give this casserole a bit of spice. Or, add some Italian herbs or fresh parsley for another layer of flavor.

Don’t hesitate to get creative and make this dish your own!

Baking for a crowd

Not only is this recipe a crowd-pleaser, but it’s also very easy to prepare for a crowd!

To feed a large group, simply double or triple the recipe. You can make a thicker casserole, or split the mixture up into smaller casserole dishes. Just be aware that you may need to adjust the baking time to account for the larger recipe size.

You can also save yourself some time in the kitchen by preparing this recipe a couple hours or even a day in advance. Make the cheese sauce, pour it over the broccoli in the baking dish, mix it together, and top with the mozzarella. Then, cover and refrigerate.

When you’re ready to bake, let the casserole sit at room temperature for about 5-10 minutes, then bake as normal! It’s so easy and means you don’t have to spend much time in the kitchen if you have friends or family over.

Broccoli and cheese casserole nutrition

Because of the macronutrients for this dish, it’s perfect for anyone following a low carb or keto way of eating!

The full bake makes six servings. At that size, each serving has 350 calories, 31 grams of fat, 9.8 grams of carbs, and 3.2 grams of fiber. This means there are only 6.6 grams of net carbs per serving.

Pair it with a low-carb protein main course like my prosciutto wrapped chicken breast with cream cheese or easy baked salmon with lemon-garlic butter for an unforgettable meal!


Leftovers can be stored covered in the refrigerator for 3-4 days.

To reheat, I recommend letting the casserole sit at room temperature for about 30 minutes, then placing the dish back in the oven at 350F until the top starts to bubble.
