Loaded potato breakfast casserole is the bomb!! It is a great way to use leftover baked potatoes, using 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! 😉
*Post update: This recipe was the first place winner in the Food & Wine Conference recipe contest sponsored by Idaho Potatoes. You can read more of those details in my conference recap, but I hope that's enough to convince you that you absolutely need this amazing recipe in your life!
The "Potato Cam" interview about my dish...
It was an amazing experience, not only for the accolades but I also received an all-expenses-paid trip to Idaho and the Grand Tetons sponsored by the Idaho Potatoes Commission. Don't miss that recap, including a private dinner just for our group by James Beard Awarded and Zagat rated chef, Rick Sordahl. I shared an inside look at the harvesting and packaging process of Idaho potatoes. I always find these behind-the-scenes tours fascinating. It's important to understand where our food comes from and how it's harvested, processed and distributed.
How To Make Loaded Potato Breakfast Casserole
Slice a few pieces off the end of the potato and remove the peel. Slice the potatoes in thin pieces, about ¼" 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. It's really important to whisk constantly when preparing.
Cool the Hollandaise and add it to 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 the remaining liquid. Cover with foil and chill overnight.
