This Ham and Cheese Hashbrown Casserole is full of tender buttery potatoes, ham, melty cheesy eggs, and savory spices.
Cheesy hashbrowns casserole is one of our favorite weekend breakfasts, paired with Banana Cinnamon Rolls or pancakes.

This easy breakfast casserole is full of allll the good things. Eggs, ham, po-tay-toes, and CHEESE, my longtime love. Best of all, it only takes a few minutes to put together!
🥣 Ingredients
Here's the basics for the ham and cheese hash brown casserole. Measurements are always in the recipe card at the bottom of the post!
- Hashbrowns - frozen
- Eggs
- Cheese - cheddar or colby jack
- Ham - pre-cooked, diced
- Butter - salted
- Milk - whole milk or 2% preferred
- Salt & Pepper
- Garlic Powder

⏲ Baking Time
If using stone or ceramic bakeware, you'll need to accommodate for time needed to heat it up. This will add 5-10 minutes onto the baking time.
Stone and ceramic bakeware heat more evenly than metal and are wonderful to bake with! Please keep in mind that if you put COLD glass or ceramic bakeware in a HOT oven it may shatter, such as if you stored the dish in the refrigerator to bake the next morning.
🔪 Instructions
START by spraying an 9x13 inch baking pan with cooking spray. Pour in hash browns (can be frozen or thawed). Sprinkle in the diced ham and half (1.5 cups) of the shredded cheese. Gently mix together.
MIX LIQUIDS In a separate bowl, whisk together the eggs and milk until smooth, then add melted butter and mix well. Add in all spices: salt, ground pepper, garlic powder, and onion powder.
POUR Egg mixture over hashbrowns, ham and cheese and mix gently until everything is evenly coated. Sprinkle remaining half of cheese over the casserole.
BAKE at 375 for 35-40 minutes, until the middle is set and no longer liquid.
🍽 Serving & Storage
This casserole is best served warm out of the oven, and is an excellent stand alone breakfast! Here are a few more serving suggestions.
- Serve with sliced fruits - berries, melon, tomatoes, or bananas are all delicious.
- Condiments - ketchup, fresh salsa, tapatio or sriracha sauce.
STORAGE: If you have leftovers, cool to room temperature, transfer to an airtight container, and refrigerate for up to 3 days.
To Freeze: Cool to room temperature, transfer to an airtight container, and freeze for up to 3 months.
To reheat, you can thaw overnight in the refrigerator and heat in a microwave or in the oven in an oven-safe baking dish.

I thought this was fantastic! I have a different recipe that uses bread and soaks overnight, but the shredded potatoes are fantastic. I will definitely be making this version again!

Yum! I halved the recipe bc 12 servings for two people is a lot, even keeping in the fridge for three days.. At first I was skeptical bc the frozen hash browns took up a lot of space in the dish (8x8) but once I mixed everything and baked it = perfection! I think next time I might try to dice some red pepper and/or shred some zucchini to add as "stealth" veggies, haha.
I did put it under the broiler for maybe 3 minutes to crisp up the edges and melt the cheese on top some more. Also, instead of pre-diced ham, I picked up some deli sliced black forest ham and diced it myself. Might not be a step others are interested in, but that way you can control the flavor of the ham (brown sugar, black forest, plain, honey, etc).
