If you’ve followed my blog for a while you might know that I already have a recipe for Broccoli Cheese Breakfast Casserole on the blog. And I probably had that recipe in mind when I improvised earlier this year and made an extra-cheesy broccoli cheese breakfast casserole for houseguests.

But the extra cheesy version was such a hit, and after I’d made it for a second set of houseguests I decided that Broccoli and Three Cheese Keto Breakfast Casserole was a recipe that had to be shared! So I made it again just for myself and snapped some photos.

And every time I ate the leftovers, I thought about what a great idea it was to combine broccoli, eggs, Monterey Jack Cheese, Feta Cheese, and Parmesan Cheese into a cheesy breakfast treat that just happens to be perfect for Keto diets. Of course, if you’re someone who doesn’t love a lot of cheese, just use the amount of cheese you prefer!

And it’s probably obvious that I love cheese, and I ate the leftovers of this for days and days and thoroughly enjoyed it every time!

What ingredients do you need for this recipe?

(This is only a list of ingredients; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

What cheeses can you use for this Keto Breakfast Casserole?

We absolutely LOVED the combination of Monterey Jack, Feta, and grated Parmesan that we used in this Keto breakfast casserole. But if you want to improvise, I think any combination of white cheeses that taste good together will be delicious.
