This overnight tater tot casserole is packed with flavor and super easy to make. Make it the night before a holiday or early morning and wake up to a cooked breakfast that's both hearty and filling.
This casserole is loaded with veggies, meats, cheeses, tater tots, and eggs giving you a full flavor dish with little effort to make.
We love waking up to easy breakfasts around here, especially on holidays because I am NOT a morning person. I'm more of a mid/early afternoon person so Brunch is definitely more my thing.
But when it's an overnight meal like this or my Cinnabon Clone Cinnamon Rolls, I can handle the morning prep because it's as easy as preheating the oven.

Cheeses- We use a blend of Monterey Jack Cheese and Cheddar Cheese.
Sour Cream- By mixing in some sour cream, we can make this casserole richer in taste.
Eggs- Use eggs as the main ingredient and binding agent.
Seasonings- You will want a combination of salt, black pepper, and cayenne powder for a simple seasoning combo.

🍴 Recipe Tips
Make it today instead of yesterday
If you want to make this overnight breakfast casserole with tater tots on the same day that you bake it, and not wait the 8+ hours you'd be sleeping then you certainly can do that by thawing the tater tots first.
I recommend laying them out flat in the baking dish as you preheat the oven so that they can warm up and thaw before being turned into a casserole. You could also just cook them like normal.
If you do not cook the tater tots beforehand or do not thaw them, then you will need to extend your baking time. This is because as they thaw and bake, they will release liquid which then causes the moisture ratio in the casserole to go up and take longer to cook to a safe temp. Remember you want the eggs cooked to 165 degrees F before eating.
You can use regular tater tots or even tater tot coins or hashbrown sticks if you have them available near you, as they will all cook up the same once thawed.
You can store your leftover casserole in the fridge (well-covered) for up to 3 or 4 days. Reheat before serving.
Yes, if desired you can simply omit the meat in this casserole for a meatless variation. It will still taste great!
Yes, it can be frozen for up to 3 months in an airtight container. Note that eggs seem to dry out or change texture slightly when they're frozen and reheated so it may not taste as great as when the casserole is served fresh.
You can reheat a single serving of casserole on a microwave safe plate for about 1.5-2 minutes in the microwave. Larger servings may take a little longer. For multiple servings, place the casserole in the oven and allow it to reheat for about 10 minutes at 350F.
