This ham and cheese hash brown casserole is a classic comfort food recipe that is the perfect addition to the breakfast menu. Southern-style hash browns are combined with diced ham, shredded cheese, a creamy sauce, diced green chiles, and baked to perfection.

I love breakfast. Some people call it the most important meal of the day, and I agree. I’m sure they’re talking about something to do with the health benefits of fueling up after sleeping or some such thing, but my love of breakfast is far less health-focused. I just LOVE breakfast food! Bacon, eggs, cheese, ham, potatoes, French toast – anything breakfast-related is absolutely at the top of my food list. And when you make a breakfast casserole? Well, you just can’t beat that. That’s why this ham and cheese hash brown casserole has been in my recipe rotation for years.
I used to make this all the time when my kids were in school because the leftovers made a great lunch or after-school snack. Now that the kids are grown, I still make this casserole quite a bit. My guy and I love it so much, we’ll eat the leftovers exclusively for a couple of days. It’s just that good!

Recipe FAQ
You can cook them either way in most cases. However, thawing the hash browns first tends to make a more crispy outside because much of the moisture is released during the thawing process.
You should always thaw your hash browns for any kind of casserole. If you try cooking them from frozen, the outside may cook on the outside but remain raw inside. They’ll also cause an uneven heat distribution because they’re essentially potato ice cubes.
