I have a zit on my chin right now, and my 2-year-old Valentine keeps poking her finger at it. “Whazzat mommy, whazzat?” It’s a pimple honey. “Oh, hippo, mommy?” No, child, but it’s about the size of one.

I don’t know what it is with my face breaking out like a 13 year old’s, maybe it’s because I’m 31 now and my body switched up the numbers on my age?? What is the deal?

In less awkward news, I am here today to introduce you to my favorite easy breakfast casserole of all time. I posted this recipe back in 2012, when my blog was still just a baby. I started with all my greatest recipes, and this is definitely one of the greats. Easy? check. Feeds a crowd? check. Tons of flavor? check. CHEESE??? Hello.

How to make hashbrown breakfast casserole

First you bake up some buttered hashbrowns in a dish in the oven, until they get nice and crispy. This is essential for achieving non-soggy potatoes. Then you layer some cheese (any kind you like) and ham on top, soak the whole thing with a few creamy eggs, and pop it in the oven! I love the flavor of the baked crispy hashbrowns with the cheesy eggs and smoked ham. It is seriously the best combo! My mother-in-law Kris found a version of this recipe in a cookbook years ago (before I married into the family) and we’ve had it for Christmas breakfast ever since.

You can make this hashbrown breakfast casserole and bake it up right away, or do it the night before and pop it in the oven before your guests wake up. (Who doesn’t love the smell of overnight breakfast casserole in the oven, especially when someone else is making it for you? Your family is going to love you this year :)

Just look at those crispy edges. Mmmm.

I will always remember one Christmas a few years ago when we were busy getting this hashbrown breakfast casserole together in the morning. My mother-in-law Kris had it all baked up and ready to go, and it was warming on the bottom rack in the oven.

She had also made some fabulous star bread, kind of like cinnamon rolls, but in a star shape. It was completely done and already on the glass serving tray, ready to be set on the table. She put it in the warm oven on the rack above our beloved hashbrown breakfast casserole. You can see what’s coming…

Yes, the glass serving tray shattered from the heat in the oven, and we ended up with glass all over the top of our beautiful breakfast casserole. SO SAD!! I remember we had to keep holding Bumpa back (Eric’s grandpa) from stealing bites. “It’s fine!” he said. We finally got a hold of it to throw it out so that we didn’t end up taking Bumps to the ER on Christmas day.

This is definitely the casserole your family needs this year, minus the shattered glass. Make it happen. Christmas only comes once a year! (Although I don’t know why we limit ourselves like this. You could totally section up this casserole, toss one serving into the microwave on a busy morning, and eat like a king on a random Tuesday. Try it! I have some in my freezer right now.

Easy Breakfast Casserole with Potatoes and Ham

Serves 12     adjust servings

This Cheesy Hashbrown Breakfast Casserole is everything you need on Christmas morning! (Or anytime you have guests for breakfast!) Frozen hashbrowns are baked til crispy, then topped with eggs, cheese, and black forest ham. It's an overnight recipe, so you have more time for stockings in the morning! Make ahead breakfasts are always a win at the holidays.  

Ingredients

  • 1 package (30 oz) frozen shredded hashbrowns
  • 1/2 cup (1 stick) melted butter
  • salt and pepper
  • 1 and 1/2 cups (packed) Monterey Jack cheese, shredded
  • 1 and 1/2 cups (packed) cheddar cheese, shredded
  • 1 and 1/2 to 2 cups black forest ham*, cut into bite-size pieces
  • 8 large eggs
  • 1 and 1/3 cups evaporated milk OR cream
  • 1 teaspoon seasoned salt
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon pepper
  • 1/4 teaspoon dry mustard powder (optional)
  • 1/4 teaspoon onion powder (optional)

Instructions

  1. Preheat your oven to 400 degrees F. 
  2. Spray a 9x13 inch pan with nonstick spray, or grease with butter.
  3. Dump the bag of frozen hashbrowns into the pan. (There is no need to thaw first.)
  4. Melt a stick of butter in a small bowl, and pour evenly over the potatoes. Sprinkle the potatoes with salt and pepper. Use a spoon to gently toss it all together, then spread it out so that it's even. 
  5. Bake at 400 degrees for 25-30 minutes, until the potatoes are tender and lightly browned on top. You can even nab a forkful to make sure they are done if you like.  
  6. Remove the casserole and reduce the oven temperature to 350.
  7. Layer the Monterey Jack and Cheddar cheese over the top of the potatoes. Add the ham. You can either leave it layered or use a spoon to gently toss the cheese and potatoes and ham together. Either way is fine. (I like to toss for a more even distribution.)
  8. In a large bowl or stand mixer, whisk together 8 eggs, evaporated milk OR cream, seasoned salt, kosher salt, pepper, dry mustard, and onion powder. Beat well.
  9. Pour the egg mixture evenly over the top of the casserole, making sure everything gets wet.
  10. Bake at 350 degrees for about 40 minutes. It is done when bubbly, when the edges start to brown and the center doesn't wiggle when you shake the pan.
  11. If the center of the casserole looks very wobbly but the top is starting to brown too much, cover with foil for the last few minutes of baking. 

Overnight instructions:

  1. Follow instructions through step 5 (bake the potatoes at 400.) Remove from the oven and let cool slightly.
  2. Follow the instructions above for layering the cheese and ham. Cover tightly and refrigerate overnight.
  3. In a large bowl, whisk together 8 eggs, evaporated milk OR cream, seasoned salt, kosher salt, pepper, dry mustard, and onion powder. Beat well.
  4.  Cover the egg mixture and refrigerate overnight.**
  5. In the morning, preheat your oven to 350 degrees F.
  6. Whisk the egg mixture once more, then pour over the potatoes in the casserole dish.
  7. Bake at 350 for 45-55 minutes. It is done when bubbly, when the edges start to brown and the center doesn't wiggle when you shake the pan.
  8. If the center of the casserole looks very wobbly but the top is starting to brown too much, cover with foil for the last few minutes of baking.

Blast from the past

Here’s the old picture of our favorite Christmas breakfast casserole (sans broken glass):

And I’ll keep my old musings from back in 2012, as well (it will explain why people are discussing lighting in the comments):

Eric and I are always arguing about the lights in our house. (It has nothing to do with the electricity bill, which is what my parents were always yelling at me about.) I like to be able to see what I’m doing. Eric likes ambiance, which means lamplight only. This is great if you have lots of lamps. Bring on the ambiance, I say, if you have enough lamps.

But we don’t. So I always get into trouble when I walk into the kitchen and flip the lights on (to see what I’m doing) and I’m always moaning to Eric that I feel like I live in the 14th century or something.

The addition of the Christmas tree has decreased contention in our home considerably. Eric loves the extra ambiance. I love Christmas. (It makes me feel more goodwill toward men, i.e., less likely to complain about living in a cave.) It’s a win-win.

I think the moral of the story here is that Christmas solves all problems.
