This Cheesy Keto Broccoli Casserole is a perfect low carb side dish for any occasion!
What’s your favorite holiday side dish? When I think of Thanksgiving or Christmas my mind jumps to broccoli casserole, sweet potato casserole, green beans casserole, and well, basically ALL the casserole recipes. Pure comfort food at its finest.
Not just for holidays, this casserole goes great with just about any protein for an easy weeknight meal. Want to make it a main meal? Add in diced cooked chicken and you’ve got a Keto Chicken and Broccoli Casserole! How awesome is that?! Rotisserie chicken works great in this.
When trying the come up with an easy way to make broccoli casserole keto-friendly I was struggling with how to replicate the crunchy fried onions without having to actually fry the onions. Enter, Moon Cheese. Moon Cheese’s cheddar cheese is the perfect crunchy topper for this Keto Broccoli Casserole and who would argue about more cheese? Cheese > Fried Onions.
The Moon Cheese creates the perfect breadcrumb-like crust that is totally to die for. Seriously, Lauren and I both couldn’t quite sneaking bites of this while making it and packaging it up. This isn’t your grandma’s broccoli casserole…it’s a thousand times better. Don’t tell her we said that though…
Here’s how to make keto broccoli casserole:
You’ll start with either fresh or frozen broccoli florets. We prefer fresh but since they’ll need to be lightly steamed a steamer bag of broccoli is always the easiest.
Want to steam fresh broccoli fast? Simply place the florets in a bowl with a few tablespoons of water and cover with a damp tea towel. Microwave for 3 minutes until tender. Easy as that!
After that, you’ll mix up the broccoli with the cream cheese, sour cream, shredded cheese, bacon(!), and spices in a mixing bowl to make a delicious cheese sauce. You’ll transfer the mixture to a cast-iron skillet (yes you can use a normal casserole dish if needed) then the broccoli and cheese mixture then gets topped with the parmesan cheese and the crunchy crushed Cheddar Moon Cheese!
Pop the baking dish into the oven and bake away until bubbly. This dish is ready in less than 30 minutes!
How to make the keto broccoli casserole ahead of time:
To make ahead of time you’ll want to prepare the casserole all the way up until you top it with the cheese and Moon Cheese. Go ahead and place in your skillet or baking dish and refrigerate until ready to bake.
This can be done 1-2 days in advance. Right before baking top with the parmesan cheese and crushed Moon Cheese.
How to store broccoli casserole:
This casserole will keep well in the refrigerator for 3-4 days after baking. Be sure to transfer into a well-sealed container, we like these glass storage containers.
How to freeze broccoli casserole:
Yes! You can freeze the cooked casserole. Transfer the casserole to a freezer-safe container and freeze up to 3 months.
To reheat simply place in the oven for 20-25 minutes until bubbly. You can also reheat in a skillet over medium heat on the stovetop.
As always, you can find the full nutritional breakdown including the carb count (total carbs and net carbs) at the bottom of the recipe card. You can find the serving size/yield at the top of the recipe card. You should always double-check your specific ingredients as different brand’s ingredients may have different values.
To get a specific serving size you’ll want to weight the final dish then divide by the number of servings. We can’t provide this information as your cooking style will vary from ours as well as the brand ingredients you choose to use.
