How to make Keto Broccoli Cauliflower Casserole
Step One: Preheat the oven to 350 degrees. Spray non-stick cooking spray on a 9X13 baking dish.
Step Two: Add the cauliflower and broccoli and then cover with foil. Put the pan in the oven and bake for 20 minutes.
Step Three: Add the seasonings with the cream cheese, mayo, sour cream, half and half, and also half of the cheese in a large mixing bowl. Mix well.
Step Four: Fold in the baked cauliflower and broccoli. Spread into a casserole dish. Top with the rest of the cheese.
Step Five: Bake for about another 15 minutes or until hot.
Change the type of cheese - While I use sharp cheddar cheese for this recipe, you can easily change the type of cheese for the best results. Mozzarella cheese is a great choice. As is parmesan cheese. This keto cauliflower casserole is a very versatile low carb side dish.
Add meat - If you want to add some protein to this cauliflower casserole recipe, adding chicken breast or bacon is never a bad idea. Just make sure that the meat is fully cooked before adding to this easy side dish.
Add other roasted veggies - There is always room for more veggies in a loaded casserole. Slice up some Brussels sprouts and add them. You can also add more cauliflower in the place broccoli should be, or vice versa.
Can I use frozen broccoli for this low-carb dinner?
It's best to use fresh vegetables if possible but frozen can be subbed in a pinch. Just be sure that you thaw and drain the broccoli before adding it to this dish.
Frozen broccoli will have a different texture and won't be the same as using fresh. You will want to make sure that it's drained really well while also having the understanding that frozen broccoli will be broken into smaller pieces.
This will make the cauliflower have a stronger taste and texture, which is fine, but just something to be aware of should you decide to use frozen.
Can I freeze the leftovers of this keto cauliflower recipe?
You can! Making and freezing leftover keto recipes means that you'll get to enjoy them again. Just let the dish cool down all the way after baking it, and then add the cheesy casserole to the freezer in a freezer-safe container.
When it's time to eat it again, thaw it in the fridge and then reheat it thoroughly once thawed.
Can I add toppings to the top of the casserole?
Just remember that anything extra added could add to the overall net carbs. Adding some bacon pieces on top, or even some more shredded cheese, would be a great idea!
Change it up each time you make it to see what you like the best.
