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.

Notes
Nutrition
I used 1/2 of all ingredients (except eggs, I used 4) as there are only of us now. I also added a 1/4 cup each of green bell pepper and green onion to the sausage when it was almost done cooking and about a teaspoon of seasoned salt added to the egg mixture. I baked in a 9″ square casserole dish, covered for 30 minutes and uncovered for another 10 minutes. It turned out delicious and my husband and I ate the entire casserole. This will be going into my “My Favorite Recipes” binder.
We’re so glad you enjoyed it and were able to make it work for you, Michelle! Thank you for trying it out. 😊
Mine took longer to cook too but it could be my oven as this has happened with other egg bake recipes I’ve tried. I do think I’ll use a little less milk next time though and may cook at a higher temp. This tasted wonderful and the family liked it. I sautéed finely diced half of a small onion with the sausage. I also added fresh raw broccoli chopped small and it cooked nicely. Great recipe that is easy to mix up in different ways. Thank you!
Every oven cooks differently so that might be it! We’re so glad you enjoyed the recipe and were able to adjust it to suit your preferences. 😊
Recipe works. It’s fast and easy. Tasty. Can be prepped in advance.
We’re so glad you enjoyed it, Crys!
Made this for Christmas bunch today. It was delicious and got gobbled up! I did add 4 more eggs, as I was feeding 8 people and thought it could use a few more. I also sauted half an onion and a half of a sweet red pepper and added to the egg mixture. Big hit! I’ll use this recipe every year from now on!
Thank you, Sally! We’re so glad it was a hit!
This casserole came out perfect. I will certainly make it again. Next time I will change from sausage to bacon and try that.
Thank you, Anne!
I don’t like frozen hashbrowns so I used a half a bag of tater tots instead. I also added dried onion flakes. Probably the best breakfast casserole I’ve made. Will definitely be my “go to” breakfast casserole from now on.
Thank you so much, Candi!
I’ve been making this recipe now for almost a year. My family requests it for every get together! I use “Simply Potatoes” from the refrigerated dairy section and use the entire 15 oz pkg and keep the remaining ingredient measurements the same. It’s absolutely delicious!
Great question can i put it together 2 days in advance and leave in frig ? First time made day of was delicious? One place looked to say one night before another showed not to do that thinking 2 days might be soggy
I wouldn’t prepare the assembled casserole in advance. You can brown the sausage in advance (the night before), then it’s just a dump and mix together in the morning and bake. I use “Simply Potatoes” from the dairy section vs frozen hash brown potatoes. It literally takes less than 5 mins to mix this together, then bake as directed.
We recommend only leaving it unbaked for one day. Any longer than that, and it’s likely to start becoming soggy!
This casserole was great. I used 7 eggs, just 1 cup of diced potatoes (obrien) and 1and 3/4 milk and 1 3/4 cheese (monterey jack). I cooked at 350 for 45 min but increased the temp to 360 for the last 15 min. Its very versatile and have been considering different additions like diced tomatoe..but overall its 5 stars from me – love how filling it is.
Thank you for the feedback! We’re so glad you were able to make it work for you and enjoyed it!
If you want to use the full 15oz package of hash browns what other ingredient measurements would need to be adjusted?
You’ll just want to make sure you have enough of the egg mixture to cover all the ingredients!
Can you make this casserole the night before and put it in the refrigerator?
Yes!
I also use the entire 15 oz pkg of “Simply Potatoes” and keep the remaining ingredients the same. I’ve made this so many times and it’s delicious just like this.
Delicious! Cook at the exact time & temp suggested & it came out perfect! Sprinkled some Frank’s hot sauce on top! Yum!
My question is.. can you refrigerate leftovers for the next day? Or is freezing necessary?
We’re so glad you enjoyed it, Dani! You can store leftovers in the fridge for up to 3 days. 😊
Can you freeze this?
Yes! Freeze: To do so, 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.
Can I use coconut/almond milk in place of regular milk?
We would recommend almond milk if you want a milk alternative!
Thank you for putting the amounts for the ingredients right in with recipe instructions! That’s so helpful!! I usually have to scroll up to see amounts then scroll back for the next direction. It’s so very helpful having it all there and I don’t have to constantly scroll up and down!
The casserole is delicious too, by the way! 🙂
We’re so glad you find it helpful and are very happy to hear you enjoy the recipe, too! 😊
Can you make this over night?
We wouldn’t recommend it as it’s likely to become soggy.
You say use frozen hash browns. How? They’re all in a lump, frozen together. Do I take a hammer & smash them apart? Doesn’t make sense. Do you mean ‘thaw package of frozen hash browns & use’? Obviously I’m not an experienced cook, and I would venture to say there are at least a few out there like me.
Hi Michael! Yes, you may need to thaw them if they are clumped together. Apologies for the confusion.
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.
