A keto broccoli & cauliflower breakfast casserole is a hearty and delicious way to start the day but perfect for a weekend brunch.
Breakfast casseroles are an easy recipe to make and can be made ahead. Cook the filling then throw it all together and bake.

Broccoli and cauliflower rice was used for this breakfast casserole recipe because I have been playing around with the combination of these vegetable rice. They go delicious together in my cauliflower broccoli risotto so I thought I would add them both to a breakfast casserole dish. Cheese was thrown in and voila! A hearty dish was baked.
I found this breakfast casserole very filling and easy to make. It’s simply another form of frittata which is one of my loves. If in doubt, throw leftovers with some vegetables in a baking dish, add cheese, eggs and voila! A tasty and healthy dish!
