Can I Make This Breakfast Casserole Ahead?

Yes! Nothing quite like having breakfast ready to go on an early morning, right? You can make this breakfast casserole ahead and refrigerate it overnight or for up to 12 hours unbaked. If you want to freeze this casserole, you will want to bake it first. Then let it slowly thaw in the refrigerator overnight and bake as directed in the recipe card.

How to Make this Tater Tot Breakfast Casserole

Prepare. Preheat the oven to 375°F and grease a 9×13 inch baking dish.
Add the first few ingredients. Place the tater tots, diced ham, (or cooked bacon or sausage) 1 cup of cheddar, and 1 cup of mozzarella into the dish. Toss with your hands to combine.
Make the egg mixture. In a large bowl, whisk together the eggs, milk, sour cream, seasonings, and hot sauce if using.
Pour the eggs into the dish. Pour the egg mixture all over the tater tot mixture. Try to make sure everything is evenly spread out.
Bake. Bake the casserole for 45 minutes. Then, top it off with the remaining half cup of cheese, return to the oven and bake for another 5 minutes until melted.
Enjoy! Let the casserole cool for just a few minutes, then slice and serve!

Storing Tater Tot Breakfast Casserole

Once the casserole has cooled to room temperature, you can store your leftovers in an airtight container in the fridge for up to 3 days. I recommend reheating leftovers in the oven until warmed through, not the microwave.
You can also freeze this baked casserole to keep it good for even longer! Bake as directed, allow to cool completely, then cover tightly in foil and freeze for up to 2 months. Thaw in the refrigerator overnight before baking.

Ingredient and Recipe Notes:

Diced Ham – This is a great recipe if you have any leftover holiday ham you need to use before it goes bad! You can also swap it for bacon or breakfast sausage if preferred.
Cheese – I like to use a combination of cheddar and mozzarella cheese. Feel free to use any other cheese you prefer, like monterrey jack, gouda, or parmesan.
Seasonings – A simple blend of salt, pepper, garlic powder and onion powder give the creamy egg mixture the very best flavor. You can add other spices for even more flavor if you’d like! Something like smoked paprika would add a delicious unique flavor.
Sour Cream – I recommend using sour cream that has its full fat content. Low fat sour cream won’t create the same thick, creamy consistency we’re aiming for with our eggs.
Eggs – If possible, try to use some eggs that have deep golden yolks. They usually yield the best results.  But, any eggs will work totally fine, you can even use a liquid egg substitute if that’s what you have!

    This was really yummy! I used full fat plain Greek yogurt in place of sour cream. I also used all sharp cheddar with a little freshly shredded Parmesan for good measure. Will definitely make again and try it with other meats!
    I halved the recipe and baked in an 8×8 dish. It took the same time and came out great!
