Easy Tater Tot Breakfast Casserole

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.

Tips for Making Overnight Breakfast Casserole with Tater Tots

If you want to make this recipe the same day 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.

How to Make Overnight Tater Tot Breakfast Casserole

Grease a 9×13 baking dish and then set aside.

Brown the sausage, onions, and bell pepper in a skillet on the stove. Make sure to crumble the sausage into smaller pieces as you go.

Set the mixture aside and return your pan to the stove. Cook you bacon and then chop it into small bits, draining grease as needed.

In a mixing bowl whisk together the milk, 1/2 cup of each cheese, sour cream, and eggs until well combined. Stir in the seasonings.

Add in the cooked meat and veggies once cooled and stir to combine.

In the bottom of your baking dish, arrange the frozen tater tots into an even layer on the bottom.

Pour your egg mixture over the top and sprinkle the remaining cheeses on top.

Cover the baking dish and place it into the fridge overnight.

When ready to cook in the morning, let the pan sit on the counter as the oven preheats to 350 degrees F.

Sprinkle the green onions on if desired. Bake covered with foil for 30 minutes. Remove foil and cook for an additional 30 minutes.

Let cool for 10 minutes before slicing and serving.

Top with salsa if desired.

Notes

Time may vary as tots will take longer to cook if they didn’t thaw properly overnight. Some fridges run colder than others. Check every 15 minutes with an instant read thermometer until internal temperature reaches at least 165 degrees F.
