Broccoli Cauliflower Breakfast Casserole

A breakfast casserole is a hearty and delicious way to start the day but perfect for a weekend brunch.

This is an easy recipe to make and can be made ahead too.  Cook the filling then throw it all together and bake.  If you make this for a weekend brunch, you can have an extra nap whilst it bakes.  I like to think of a keto breakfast casserole as a massive egg muffin cup.

Although this is called a breakfast casserole it can be eaten at any time.  The Chief Taster dined off this whilst I was away on a trip for a couple of days.  I was surprised at how much he enjoyed this and I know he did not heat this up which testifies that it is great cold.   I didn’t get any calls on how to work the oven so that’s how I know he didn’t heat up this dish!

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.

Low Carb Breakfast Casserole

A lot of breakfast casserole recipes will have meat in them so feel free to add sausages or ham to your creation.   This broccoli cauliflower breakfast casserole is delicious even for meat eaters though.  Perhaps have your sausage on the side and enjoy a slice of this first before you get creative.

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!

What to Serve with a Breakfast Casserole

Although this low carb breakfast is a hearty meal it is extra delicious with a low carb side. Make a breakfast into a hearty lunch with a batch of keto veggie breakfast biscuits. Serve with a side of low carb hash browns too!

    What would it be like without the cheese? Lactose intolerant, sadly. I like the idea of cauliflower and broccoli for breakfast with eggs, of course!

      I think it would be do-able….Just like a solid frittata really.

      That’s a good idea to freeze it! I might have to do that when cauliflower is on a special price here! I’d say that the cauliflower would be 250-300g and the broccoli 300g
