Notes

This is a wonderful use for leftover ham, but when I haven’t had leftover ham, I have purchased a ham steak from the store.
Here’s a great twist on the recipe: Try using a variety of breakfast meats like ham, bacon, and sausage for a tasty change! Trust me, it’s amazing.
I personally always recommend shredding cheese by hand for the best flavor and texture. Hand-shredded cheese melts better as well. (Rotary cheese shredders are the best and I always use them). However, I’ve used bagged cheese in this recipe and it worked fine when in a hurry.
I’ve used recipes where you thaw the hashbrowns in advance or don’t precook them. This method, though, gives the potato layer so much more flavor that it is not bland and helps prevent the potatoes’ texture from being too mushy, for lack of a better word.
The casserole can brown a little on the edges, and to prevent excessive browning, I do recommend checking earlier, around 30 minutes, and covering with foil.
Occasionally the middle of the casserole doesn’t seem quite done at 45 minutes. 50 minutes should be plenty, but you may need to cook slightly longer to ensure the casserole is cooked sufficiently.
You could very easily add chopped onion and/or peppers to the casserole if desired, which I generally do with sausage, but opted not to with the ham and used onion powder and an optional chive or green onion garnish instead.

Don’t you just love waking up to the smell of breakfast cooking? In our house, that often means the Ham and Hashbrown Breakfast Casserole is in the oven. It’s a recipe that’s close to my heart, not just for its delicious flavors but for the memories it’s helped create.

Weekend mornings are a big deal for us. It’s the one time everyone is home, sipping coffee and enjoying plates piled high with this cheesy, ham-filled delight. I remember the first time I made it; I was a little nervous about whether it would be a hit. But when I saw everyone dive back in for seconds (and sometimes thirds), I knew we had stumbled upon something special.

Casserole Tips

  • Choose the Right Hashbrowns: Opt for a high-quality brand of frozen hashbrowns. Some brands may contain excess moisture, which can make your casserole soggy. If you notice the hashbrowns are particularly icy or wet, lay them on a kitchen towel and pat them dry before use.
  • Customize the Cheese: One other main change is the cheese. I’ve used pepperjack instead of Monterey jack. You could easily do all cheddar or substitute Swiss for Monterey jack or mozzarella. You don’t have to add mozzarella, either. The key thing is that you use 3 cups of cheese. It sounds like a lot, but I wouldn’t use less.
  • Egg Mixture Consistency: Whisk the egg mixture thoroughly until it’s completely homogeneous. This ensures the egg cooks evenly throughout the casserole, preventing any rubbery or overly dense spots.
  • Oven Temperatures May Vary: Know your oven. Some ovens run hotter or cooler than the temperature dial indicates. If you know your oven runs hot, consider lowering the temperature by 10-15 degrees. An oven thermometer can be a great tool to ensure accurate baking temperatures.

Key Ingredients and Tools

  • Frozen Shredded Hash Browns. You’ll find these in the freezer section of your grocery store, near other frozen potatoes. They’re a convenient time-saver and ensure a consistent texture throughout the casserole.
  • Evaporated Milk. Located in the baking aisle, evaporated milk adds a creamy, rich texture that regular milk can’t match. If you need a substitute, cream or half-and-half could work, but the final taste will alter slightly.
  • Ham. This can be found in the meat section, and using leftover ham or a ham steak adds depth and savoriness. If you’re looking for a vegetarian alternative, consider smoked tofu or a similar smoky-flavored protein.

  • 9×13 Pan. This size is perfect for the amount the recipe makes, allowing for even distribution of ingredients and proper cooking. It’s the ideal size for feeding a crowd or having leftovers.
  • Cheese Grater. Freshly grated cheese melts more smoothly and integrates better into the casserole compared to pre-shredded cheese, enhancing the overall texture and flavor.
  • Mixing Bowls. A set of mixing bowls is essential for combining the egg mixture and seasonings evenly before pouring over the hashbrowns and ham, ensuring every bite is flavorful.
  • Whisk. Using a whisk to blend the eggs and evaporated milk creates a uniform mixture that cooks evenly, preventing any unmixed egg whites or yolks in your casserole.
  • Aluminum Foil. Covering the casserole with aluminum foil if it browns too quickly on top ensures that it cooks through without burning, keeping the top perfectly golden.

Serving Suggestions

Serve with fresh fruit salad and sourdough English muffins, mixed green salad, and sliced avocado.

Troubleshooting and Help

Can I make this casserole ahead of time?

Absolutely! You can prepare it up to step #5 the night before. Just keep the egg mixture separate and pour it over right before you’re ready to bake. This makes your morning a breeze – just pop it in the oven!

Is it okay to use a different type of cheese?

For sure! Feel free to mix and match your cheeses based on what you like or what you have in your fridge. The recipe is super flexible. Just aim for about 3 cups total. A mix of different cheeses can actually add some nice depth

What if I don’t have evaporated milk?

No worries! Cream or half-and-half are great substitutes. They’ll change the flavor slightly but still give you that creamy texture. It’s all about using what you’ve got on hand

Can I add veggies to this casserole?

Yes, and that’s a great idea! Chopped onions, bell peppers, or even some spinach can add a nice touch of freshness and make the casserole a bit more colorful. Just sauté them a bit before adding to make sure they’re not too crunch

You can’t go wrong with this dish! Whether you’re planning a family breakfast, a brunch with friends, or just want to enjoy a hearty meal at home, your casserole will surely be a hit.

Storing Leftovers

In the Fridge:

  • Let the casserole cool down to room temperature after cooking.
  • Cover the baking dish with aluminum foil or plastic wrap. If you prefer, you can also transfer individual portions into airtight containers.
  • Store in the refrigerator for up to 3-4 days.

Freezing:

  • For freezing, it’s best to cut the casserole into portions for easier reheating.
  • Wrap each portion tightly in plastic wrap and place it in a freezer-safe bag or container. This method helps prevent freezer burn.
  • Label the container with the date, and you can freeze the casserole for up to two months for the best quality.

Reheating:

  • From the Fridge: Reheat in the microwave for 2-3 minutes, checking and stirring (if possible) halfway through. Or, heat in the oven at 350°F (175°C) for about 20 minutes or until heated through.
  • From Frozen: It’s best to thaw a frozen portion in the fridge overnight before reheating. Once thawed, follow the fridge reheating instructions.
