Breakfast Casserole Recipe

by Alice Currah on December 20, 2009. Updated December 23, 2010


All the holiday cookies and treats have been baked. Presents still need
to be purchased, wrapped, and placed beneath the Christmas tree. It’s hard to believe that in just a few days my kids will be running to our family room at the crack of dawn to see what Santa brought them. I typically wake up around 6am to bake cinnamon rolls and make coffee so when the family wakes up the smell is permeating throughout our house.

From there I sneak back into bed and listen for the sound of feet running across our creaking hardwood floors towards our bedroom. The kids will be shouting at us with joy and excitement begging us to get up so they can open presents. From there, I go straight to the kitchen to pour my husband and I a cup of coffee, remove the cinnamon rolls from the oven and replacing it with our traditional Breakfast Casserole to bake. While we wait for our casserole, our family enjoys opening presents and eating freshly baked cinnamon rolls. This has been our tradition for the past 10 years and every year I look forward to it.

This Breakfast Casserole is the type of dish to finish the year off right. It’s what I affectionately called my “No Guts- No Glory-No Mess” breakfast. Its high in calories and filled with cheesy, heavy cream goodness. I love everything about this casserole from the tater tots to the insane amounts of heavy cream and shredded cheese. Then there is the pound of sausage sautéed with onions and mushrooms.. GLORY!

If you are looking for a savory breakfast casserole to serve your family this Christmas Season or the next gathering, look no further. Enjoy!


Breakfast Casserole


1 pound of mild sausage

1/2 onion, chopped

8 oz package of sliced mushrooms

2 cups frozen tater tots

6 slices white bread, cubed in large pieces

8 oz package sliced mushrooms

3 cups of grated extra-sharp Cheddar cheese

8 eggs

1 cup heavy cream

1-1/2 cups of milk

1 teaspoon Dijon mustard

1/2 teaspoon salt

1/2 teaspoon pepper

1 tomato, thinly sliced


In a medium skillet, brown sausage, onion, and mushrooms until sausage is no longer pink. Spray a 9×13 casserole dish with non-stick cooking spray. Place the tater tots in the casserole dish followed by a layer of the bread cubes. Add the sausage, onion, mushrooms over the bread and sprinkle an even layer of cheese. In a medium bowl, whisk the eggs, cream, milk, mustard, salt and pepper. Pour the egg mixture over the casserole. Layer the top of the casserole with sliced tomatoes. Cover with plastic wrap and refrigerate overnight. The next morning, remove the casserole from the refrigerator and preheat oven to 350 degrees F. When the oven is ready,remove the plastic wrap and bake casserole for 1 hour. Enjoy!

Looks absolutely easy and delicious! We’re basically snowed in here, so I am thinking of making this today for brunch…

This looks like it is worth every heart-stopping calorie! What a great way to indulge before the post holiday resolution days

Yum! I’ve seen lots of recipes for breakfast casseroles similar to this but they almost always have a mexican theme with chilis in them. I would like that but not my extended family so I’ve never made one. I’m excited to try this out! Thanks.


jenn December 20, 2009 at 2:23 pm

You do have leftovers right? Because I haven’t had breakfast yet. Really I haven’t. Yum!!!


Cheryl December 20, 2009 at 3:31 pm

Yum! I think I might have to try this one! Ooey, gooey goodness!


Chris December 20, 2009 at 4:21 pm

This looks like a nice upgrade on the normal breakfast casserole we do at Christmas. I’ll have to give it a spin.


Gaby December 20, 2009 at 6:05 pm

o.m.g. this looks fantastic! All that cheese just makes it irresistible! And the mushrooms and tomatoes – I have to make this for my parents in Seattle next week!


Elizabeth December 20, 2009 at 6:16 pm

This looks perfect for a winter morning. Yum.


jenjenk December 20, 2009 at 7:29 pm

Sara December 20, 2009 at 7:35 pm

This is my favorite breakfast casserole!!! So yummy!! My family has made this breakfast casserole every Christmas morning since I can even remember! It is so delicious! Thanks for sharing.

Best rEgards,

My 20′s-something nephew “informed” me last night that a “tater tot casserole” was at the top of his requested-food-list for this year’s Christmas morn; so, like all good aunties I googled all the ingredients that he could conjure up from his childhood memory… eventually leading me to your site! Your pictures are the clincher for me, in addition to the fact that Morning Star is now putting out a vegetarian “sausage”, making this recipe a real possibility for our new Christmas-memory-making opportunity :) Thanks so much for sharing!

This is the perfect casserole dish for a cold and snuggly morning. Perfect for my kiddies!

Merry Christmas!

EVERY single thing you post on this site is something I absolutely LOVE~! Thanks, Alice!

Can you tell me how many this will serve? 6-8?


Hélène December 24, 2009 at 2:32 pm

Happy Holidays!


erica December 25, 2009 at 8:02 pm

I made this for Christmas morning and it was such a big hit! I have been really hesitant about breakfast casseroles for some reason…unchartered territory, I suppose. But this one was fabulous. Everything blended together so beautifully and was terribly easy to put together. I loved that all I had to do was pop it in the oven and walk away for an hour. Thanks, again.


dndtaylor December 26, 2009 at 5:10 pm

I to made this for Christmas morning, it was a HUGE hit. The leftovers this morning are just as delish! I added green peppers to the egg/cream mixture for some added color/flavor. This for sure will become part of our holiday tradition. Thanks so much for sharing such a special and delicious part of your holidays with others. My husband and daughter thank you as well!


Jen @ My Kitchen Addiction December 26, 2009 at 9:57 pm

This looks wonderful! I’m finally getting back to all of the posts I missed in the last week or so… Wishing I had seen this *before* Christmas morning! I might just have to give it a try one day next week. Hubs would love it.


Cheri December 28, 2009 at 10:27 pm

I made this for my family Christmas morning but didn’t plan ahead. I pulled it all together and let it sit for 15 minutes and it was GREAT! My family loved it! I used seasoned tator tots and substituted milk for the cream. I will definately make again.


Leanne January 3, 2010 at 2:30 pm

Thank you so much for this recipe. It is seriously one of the best casserole dishes on earth! My friends and family just couldn’t stop eating it this morning. We had to all take a very long nap afterwards from our casserole comas! : ) Will definitely be making this over the holidays for many years to come.


Corinna March 4, 2010 at 1:57 pm

This looks great! You mention cinnamon rolls though and I am unable to find that recipe on your blog. Am I looking in the wrong place?


Laura April 8, 2010 at 10:45 am

Can this be frozen for later?


christina July 19, 2010 at 2:53 pm

Hi Alice,

Do you use dijon mustard or the really brite yellow mustard/



christina July 19, 2010 at 3:02 pm

Hi Alice,

Do you use dijon mustard or the really bright yellow mustard? Do you think it would work with frozen hash browns instead of the tater tots?



kristen October 15, 2010 at 10:57 am

yum… my husband made this for christmas last year and now i have one baking in the oven for a breakfast potluck today. thanks for hooking me up with an awesome recipe! it’s like christmas in october, so happy!


Andrea Jasmin November 12, 2010 at 11:21 am

I REALLY enjoy your blog!

My best friend and I visit each other about once a month and always slave in the kitchen on Saturday morning for our husbands and 3 kids. Not anymore! we made this and love it and have now named it OUR breakfast strata and vow to make it for years to come. It was delicious and we made it a tiny little bit healthier with fresh whole grain bread, half and half, and turkey sausage and we also used dijon mustard. DELISH!


Sophia March 3, 2011 at 10:15 am

This is really good information. You have done an excellent job of research and writing.


holley September 2, 2011 at 10:57 am

Delish… took for the office brunch and it was gone in a nano second. I used all milk and omitted the mushrooms (for a co-worker that is allergic) Also used 4 c. Tater Tots. Would be awesome with peppers mixed in with the onion and sausage mixture. Could also substitute ham or bacon for the sausage. Thanks for another great recipe Alice!!


Netty December 20, 2011 at 10:46 am

Alice, this looks deliciously amazing! Do you think it can be made without the bread or would that compromise the texture too much? Was thinking to sub in some more veggies… :)


Ker-Yng December 23, 2011 at 8:53 am

I made this last year and it was a hit. Will make it again this year. Thanks! :)


NoNoNannette November 11, 2012 at 8:59 am

I love this recipe I also love Mushroom your recipe call for, 8 oz package sliced mushrooms, but it call for it TWICE so do I need 16oz. of sliced. YES! finely a recipe the doesn’t call for any of the bell pepper family ( I do like chile peppers just not the bell family :~) Thanks again for the GREAT RECIPE =^..^=


Ruth November 11, 2012 at 11:44 am

You have 8 oz mushrooms in there twice….just a mistake?


Gloria Barnhouse November 11, 2012 at 3:04 pm

Why can’t I print this recipe? I can’t take the computer to the kitchen. It looks so very good and easy.
