Loaded potato breakfast casserole is an easy casserole recipe, perfect for breakfast, brunch, or even dinner! Loaded baked potatoes made easier, and enough to serve a crowd!
Loaded potato breakfast casserole is the bomb!! It is a great way to use leftover baked potatoes, since you use chilled baked potatoes in this dish. I incorporated homemade Hollandaise sauce in the casserole for incredible flavor. It’s the same sauce I use in my breakfast potato stacks recipe.
This is definitely not your mama’s egg casserole dish! 😉
Slice a few pieces off the end of the potato and remove the peel. Slice the potatoes in thin pieces, about 1/4″ width and set aside. Then whisk the milk and egg mixture together until blended.
Now make the Hollandaise. Homemade Hollandaise sauce gives this recipe great flavor. Be sure and whisk constantly when preparing.
Cool the Hollandaise and add into the milk mixture. Place half of the potatoes in the bottom of your baking dish.
Top with ham, bacon and cheese. Pour half of the milk mixture on top. Repeat with one more layer and pour over with remaining liquid. Cover with foil and chill overnight.
