Make-Ahead Overnight Tater Tot Breakfast Casserole
This make-ahead overnight tater tot breakfast casserole is honestly the best! All of breakfast’s favorites in one handy casserole.
Looking for perhaps the newest, bestest, most amazingest breakfast casserole to wow everyone who happens to be lingering around your house waiting for you to feed them in the AM?
I think I have the answer (other than sending one of the lingerers out for a donut run).
I kid you not, this make-ahead overnight tater tot breakfast casserole is easily one of the most delicious things I’ve EVER eaten for breakfast (or just possibly ever). It’s a mishmash of all the good breakfast things: potatoes, eggs, sausage and cheese.
Every time I make this, I shamelessly hoard all the leftovers, because come to find out, it’s equally delicious as a warmed up (or yes, cold, don’t cringe) lunch or next-day breakfast.
What makes it so good
There is a lot to love about this tater tot breakfast casserole.
Because it’s made the day before and popped in the oven less than an hour before you want a warm breakfast, it is perfect for busy holidays and/or when you are entertaining company. Won’t they be ecstatic when they wake up to the savory aroma of this breakfast casserole wafting throughout the house!
Bonus: you didn’t have to get up at 4 a.m. to make it happen.
The tater tots, after sitting overnight and then being baked, meld into this delicious compact layer of tender potatoes surrounded by the eggs, sausage and cheese.
Are tater tots created equal?
I don’t have a strong brand preference on tater tots. I mean, they’re tater tots. Is there a standout? Please inform me if there is.
I try to pick up a bag or two from Trader Joe’s when I’m there, but otherwise, any frozen tater tot is going to do fine.
Scatter the tater tots in a single layer in the bottom of a 9X13-inch pan. It’s ok if there’s a few gaps and holes. No one is going to notice you’re carefully arranged pattern after it all bakes, so just toss them in.
The browned sausage and veggies (onions and peppers) scatter across the top of the taters followed by the cheese.
Substitutions
Meat: You can use chopped ham or bacon in place of, or in addition to, the sausage. I also think you could easily make this meatless (I’d add more vegetables for some bulk and texture if doing so).
The simple addition of onions and peppers add great flavor to the casserole. As in, I don’t think you should leave them out. Even my resident pepper-haters gobble this up.
Vegetables: You could change up the vegetables or add to them based on preference. Some other ideas: lightly steamed broccoli or carrots, mushrooms, zucchini.
Cheese: I like to use a combination of grated sharp cheddar and Monterey Jack. But I think the cheese is wildly adaptable. Maybe Swiss? Gruyere? Pepper Jack? Remember: grate your own cheese for maximum melty creaminess.
The simple egg + milk + sour cream mixture gets poured all over the top.
The egg mixture isn’t going to soak in as much as a breakfast casserole made with bread, but don’t be worried. I promise it’s all going to work out.
Just cover with some greased foil, pop in the fridge, walk away, and try not to stress. UPDATE: many of you have reported back that you can also just bake this right away, too! The tater tots won’t break down quite as much, but it still works AND it is delicious.
The next morning when you go to bake this amazing casserole, don’t uncover.
You’ll pop it right in the preheated oven covered. It’ll bake for 20 minutes or so and then you can uncover to let it bake to its full golden, bubbly potential.
You can tell the casserole is done baking when it’s puffy and set and the middle isn’t gooey and wet (the eggs will be fully cooked).
I like to toss some fresh chopped chives or green onions on top because it’s pretty, but that’s totally optional.
This make-ahead overnight tater tot breakfast casserole cuts beautifully into squares. Another point in its favor!
Could it stop being such a teacher’s pet. Seriously. It’s pretty much perfect in every way.
And as I mentioned above, it’s delicious served warm for an amazing, hearty breakfast, but it also makes great leftovers.
Flavor Combinations
I like to eat it with sour cream and salsa. It gives the tater tot breakfast casserole a Mexican-flavored food vibe which could be even more amped up by using pepper jack cheese in place of the Monterey Jack.
I think there are a lot of other flavors that could be championed in this casserole. I haven’t thought through all the details but a few ideas that come to mind are:
- ham and Swiss version
- broccoli cheese version
- cheesy taco version
- maple bacon version
- what else?
I’m excited to see where this make-ahead breakfast casserole takes you. It is 100% the breakfast casserole of choice happening here over the holidays.
It’s one of those recipes that’s going to be a staple for years and years to come.

Instructions
- In a large skillet over medium heat, cook the sausage, peppers and onions, crumbling the sausage into small pieces as it cooks, until it is no longer pink and cooked through and the veggies are tender. Drain the grease (you can let the sausage/veggies hang out in the skillet for a minute or remove them to a plate).
- In a medium bowl, whisk together the eggs, milk, sour cream, salt and pepper until smooth.
- Lightly grease a 9X13-inch baking pan. Place the tater tots in a single layer across the bottom of the pan. (Use only as many tater tots as will fit in a single layer).
- Sprinkle sausage over the tater tots followed by the veggies. Sprinkle cheese evenly across the top.
- Pour the egg mixture evenly over and across the top. Cover the dish with lightly greased foil and refrigerate (overnight, up to 18 hours). OR you can bake it right away. The tater tots won’t break down quite as much, but it is still delicious.

Absolutely LOVE! Best breakfast casserole I’ve ever had! I was hoping to meal prep it – bake the casserole and freeze individual portions to be reheated on busy mornings. Have you frozen it after you baked it?
Yes, works great!
Ok, I have to comment because this recipe saved me. I was hosting a breakfast for 70 people the day after we got home from a week long trip. I made these casseroles before I left and froze them for a week. I pulled them out of the freezer the night I got home and baked them the next morning. They were fantastic!! Easy, delicious, and froze wonderfully for anyone wondering.
That’s exactly what I was wondering and yours is the first comment. Perfect! Thanks for sharing your experience with freezing!
Did you bake before freezing?
I made this dish for Sunday Brunch at my church. I made the day before with 2 modifications: Save the egg mixture until you are ready to bake it and, therefore refrigerate the layered tater tots, the sausage, veggies, and cheese in a covered baking dish overnight.
You know it’s a keeper when you come back to it again and again! We change up the meats and veggies all the time. After it’s cooked, it makes an excellent breakfast burrito filling, too!
First off I’m not a good cook. Mostly because I haven’t cooked much in the past. So one year I said I’ll do Christmas day breakfast. They looked shocked. Did as much as I could the night before, placed all the wet ingredients in a jar to go. With all ingredients in a lil cooler I traveled to my Sisters. The next morning tossed it together in minutes, & let sit. Tot casserole, artisan toast and fresh fruit was a hit! ALL loved-loved it! I’m just afraid they want me to do holiday breakfasts from now on. Oh nooo what have I done! Lol, Thanks for the awesome-easy recipe!
Has anyone made the tater tot breakfast casserole and froze it before baking it? I would like to make week or two beforehand
It freezes great, Karen! I prefer baking it once it has been thawed.
We loved this recipe. We assembled and then cooked it immediately. I used 10 eggs, and the cook time was quite a bit longer. In looking at other reviews, I think that has to do with the fact that it did not sit overnight in the fridge. I think the cook time would have been spot on making it ahead. Delicious flavor, and we will definitely make this again.
Hi Mel, are you saying that it is best to thaw the tater tots overnight and then use them at room temp? i want to be sure the casserole is not soggy. Thank you so much!
No, I use the tater tots frozen when I assemble the casserole. It shouldn’t be soggy if the casserole is baked long enough, so don’t be afraid to add time if needed.
So good and super easy. It will be my breakfast or brunch potluck go to . Thanks for the great recipe.
Made this for Christmas Day and am making it again for New Years Eve! This is so easy to put together.
Could I substitute Greek yogurt for the sour cream
Yes, I think so.
