Breakfast Casserole Tips For Success
Make ahead: You can easily make this casserole the night before and bake in the morning. Just cover in the fridge and take out while your oven is preheating. You may need to increase the baking time by 10-15 minutes.
Baking Tip: This casserole is done when the edges are set and lightly brown and the center only jiggles slightly. Make sure there is no “watery” eggs in the center before removing from the oven.
Storage: Cover the entire casserole with foil or a lid to your baking dish and refrigerate for up to 3 days.
Reheat: Reheat in the microwave.
Freeze: This casserole can be frozen. First bake your breakfast casserole and once it has completely cooled, place in an airtight container or ziplock bag. When ready to warm up, place in oven and bake at 350 degrees until warmed through about 20 to 25 minutes.

Look at all that cheesy goodness! Doesn’t it make you want to have a piece right now?! Well, what are you waiting for?

I used potatoes O’Brien instead of hash browns because the store was weirdly out of hash browns. The potatoes O’Brien added a lot of flavor! I also added a small can of green chiles and some green chile salsa to the sausage after I browned it. It made the mixture a little more wet, and I had to leave it in the oven a little longer, but it tasted amazing!
Thank you for the feedback, Ariel! We’re so glad you were able to make it work for you.
I have made this so many times and every time it’s a hit. In fact I just slide one into the oven. So easy to make, even for a non cook like myself. I especially like the clear directions given to prepare this dish. When I tried the overnight way I had to add a lot of cooking time so next time I cooked it, refrigerated it and then each person could microwave their portion. Whenever this dish comes out it’s a buffet style brunch so it’s okay to wait your turn at the microwave. This is my go to. I have switched up ingredients like adding veggies to the egg mixture, or using different cheeses and hashbrowns. Always goobled up.
We’re so glad you enjoy the recipe, Penny! Thank you for trying it out and taking the time to leave your feedback!
This is my favorite breakfast casserole! I usually use mild sausage but I have also tried it with ham after Easter.
Thank you so much, Carrie!
If you add fresh spinach,bell peppers and green onions and broccoli, do you have to sauté it before you add it
We would recommend sautéing first as the taste and texture will be improved. Hope this helps!
I covered it as it said for 45 minutes, but it barely cooked. Took the foil off and baked it for an hour, and then it was perfect. Very easy and delicious recipe and we ate off of it for a few mornings
We’re so glad you were able to make it work for you and enjoyed it, Amy! Thank you for the feedback.
It definitely needs to stay longer than the given time she stated.
Hello! I made this recipe and it’s absolutely delicious and easy, I would say it took a little more than an hour for me (in total) because I used 3 potatoes instead of frozen hash browns, and it took a little more time to cook them for some reason, beside that I’m amazed, I also added I tsp of garlic powder and half medium onion, and it turned very good, my husband loved too! Thank you for this amazing recipe 💗
Thank you for trying it out and coming back to let us know how it went, Alejandra. We’re so glad you enjoyed it!
Great recipe! No issues at all and the milk is not too much. My guess is people having issues don’t realize that just because your oven says it’s ready doesn’t mean it’s up to temperature! Best thing we ever did we get an oven thermometer. Most of the time ours will be “preheated” but only around 200-250 degrees and not 350. Definitely not a recipe issue for anyone who is concerned, just make sure your oven is REALLY up to temperature!
Thank you for the feedback, Rachel! We’re so glad it turned out well for you. 😊
This recipe is actually really good. I do agree with everyone that the ratio of egg to milk seems wrong. At 45 minutes, it was still soup. But if you let it cook for another 30 minutes, checking often, it turns out wonderful. Maybe she has a much better oven than I do, I don’t know, but I will say it was worth the wait.
Thank you for the feedback, Heidi! We’re so glad you enjoyed it.
We loved this recipe, I used 1 extra egg a little less milk (using 2%), mixed half the cheese with the eggs, substituted bacon for sausage and cooked hash brown rounds in the air fryer before hand. I cooked for 30 minutes covered at 350 and took off the cover for 10 minutes. It turned out great. My kids loved it. Next time may add chives.
We’re so glad you enjoyed it, Ali!
Love how easy this recipe is! The first time I made it I felt like I needed to adjust the amount of milk because, hey, ovens vary. Second time I made it, I used 1.5 cups of milk and baked at 350 for 55 minutes (uncovered for last 15). Came out perfect!!
We’re so glad you were able to make it work for you, Whitley!
I have always made it with 6 slices of bread torn into smaller pieces with the 2 cups of milk. Mix everything cover and refrigerate over night. Cook at 350 for 40 min. I have also uses smoky-links sliced to coin like size instead if sausage. Not soupy at all.
Made this recipe for my first time.Only adjustment I made was using half of a 26 oz bag of hashbrowns, because that’s what I had. Turned out great! Will definitely make again.
We’re glad it turned out well for you!
No way this recipe is only 2g carbs. Matters not since I’m making it for someone else. When you count macros you learn an approximate range for ingredients. I wish it was only 2g per serving, I’d eat this up! 😀
Thanks for catching that! We adjusted the recipe card. 😊
everything looked great until we cut into it, then it was sitting in a puddle of water. What gives?
Sorry to hear this, Savannah! Sounds like it just needed a little longer in the oven.
Easy and delicious recipe. Thanks for sharing it!
Thank you, Barbara!
I usually make this same thing in the crockpot overnight for Christmas morning. Who wants to cook breakfast on Christmas morning? Not me. The only exceptions are: one 30 oz bag of frozen shredded hashbrowns, 1 lb cooked and drained sausage, 4 cups shredded cheese, 12 eggs, 1 cup of milk, and your seasonings. Mix hashbrowns, cheese, and sausage together, pour egg mixture over top, cook on low in crockpot for 8 hours. And Christmas breakfast is served. I came here because I’m basically making the same thing after work for a week night dinner and I needed oven temps and time. 2 cups of milk sounded like alot to me, but I did it and we’ll see!!
Thank you for trying out our recipe! We’d love to know how it turns out!
Hi Stephanie! How did your casserole turn out with 2 cups of milk? And did you use whole milk? I normally have 2% on hand.
Will it work if the hashbrowns aren’t frozen?
Hi Kelly,
It should work with thawed hash browns. Just be sure to keep a close eye on the oven, and adjust the baking time as needed!
Can you use bacon instead? I have family members that are pretty fussy
We doubled everything to feed the amount of people we had. And it just seemed like so much milk. After the 45 initial minutes it was still swimming in milk, and not close to being set. We raised the temperature to 400° and cooked for another 20 minutes. Then we put the cheese on the top instead of inside and cook for another 15. Came out perfect. But we may adjust the milk next time.
We’re glad it turned out well for you! Please let us know how it goes if you do try it again and adjust the milk. 😊
