Ingredient Notes and Substitutions
- Tater tots Frozen tater tots are the best for this recipe. If they’re not an option for you, consider making a hash brown breakfast casserole instead.
- Eggs – This recipe works best with large eggs, but medium or extra-large will work if needed.
- Cheese – Shredded cheddar is the classic choice in most breakfast casserole recipes. You can substitute with any good quality cheese that melts well.
- Milk – We use whole milk because it gives a custard-like consistency to the baked eggs, but with fewer calories than heavy cream. Feel free to use Half and Half or heavy cream for a more indulgent dish.
- Precooked ham – We usually make this recipe using leftover crock pot ham. However, even thick slices of deli meat will work fine for this ham and tater tot casserole.
Breakfat Casserole Recipe Variations
- Use a different protein: Not a fan of pork? Not a problem! Use turkey, chicken, sausage, or bacon. Or, leave out the meat and include extra veggies instead.
- Play with the seasonings. We use a basic, all-purpose seasoning for the ham egg and cheese casserole. Give it Tex Mex flair by using a tablespoon or two of taco seasoning. Or, use your favorite Mediterranean or Italian spice blend.
Add a kick of heat to the casserole by swapping half of the shredded cheddar cheese with shredded pepper Jack.
- Lighten it up with lower fat milk. This breakfast casserole turns out well using 2% fat milk, if you prefer. We do not recommend using 1% or skim; they don’t have enough fat to help support the weight of the veggies and ham. You’ll end up with all of the ham sitting on the bottom of the baking dish.
Low Carb Ham Egg and Cheese Casserole
If you’re looking for a keto option, leave out the potatoes. As much as we love breakfast casseroles with potatoes, they do have a lot of carbs!
- Don’t let the frozen potatoes thaw out.
Keep the tots in the freezer until you’re ready to layer them in the baking dish. Otherwise, they will become mushy and lose their crispiness in the oven.
- Whisk the eggs really well.
Don’t be shy when you’re beating the eggs. To create a thick, custard-like base, you need to combine the whites and yolks completely. It’s similar to what you do for a French toast casserole or when making fluffy scrambled eggs.
- Shred the cheese yourself, for the best meltability.
Oh, and be sure to set one cup of the shredded cheese aside; it goes on top of the ham and tater tot casserole just before baking.
- Use the right tools for the job.
To create the tater tot crust, you’ll need a flat bottomed glass, or a spatula, to smash the tater tots. Be sure to use one that’s one solid piece, without any holes or slits in it.
- Remember to lower the oven temperature.
After you smash the potatoes, you will need to lower the oven temp, down to 400ºF. Otherwise, your crust will burn.
Pour the egg mixture over the tater tots crust. Add diced ham. Then top with the last 1 cup of cheddar cheese.
Bake for 20-25 minutes, until the eggs are set, the cheese is melted, and the top is golden and bubbly.
Storing and Reheating
Store your tater tot breakfast casserole in the fridge for up to 5 days.
To prevent the eggs from drying out, cover the pan with aluminum foil, or transfer the leftovers to a covered container.
Reheat the ham and tater tot casserole in a covered baking dish in a 350°F oven until it’s warm all the way through to the center. Reheating usually takes 15 to 20 minutes.
Of course, a microwave will do the job too. But, to prevent the eggs from becoming rubbery, we recommend microwaving at 50% power.
