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.

Can you mix up and bake the next morning?
It was good and really easy to come together. I’m just trying to figure out why it came out runny. I cooked it for over an hour and it still looks runny. Not sure what I did wrong.
I added an extra egg in and used a bag of hash browns that was not frozen (in the cooler section). I think the frozen hash browns might have too much extra moisture.
Is that 15 oz. of potatoes or 1/2 a 15 oz. bag?
I’ve made this three times in the last two months, because my partner is obsessed. thank you!!!
I made a lighter version, which turned out very well. I used turkey breakfast at sausage, which I doctored up with a spicy seasoning blend, cayenne and red pepper flakes. I also used shredded mozzarella as the cheese. It was very tasty. Next time I’ll try adding peppers and onions as someone else suggested. Thanks for the great recipe!
I’ve made about 4 or 5 different versions of this dish using the original recipe as the starting block. Tex-Mex with cheese blend, avocado, salsa, and seasonings. Meat Lovers with bacon and ham added. Garden with bell peppers, onions, spinach, etc. My kids crush it everytime with no leftovers. Excellent recipe to use your imagination with. Greatly appreciated!
I set my oven to 375, left off the foil, and baked for around 40 minutes (basically until the edges were set and no runny eggs in the middle). Didn’t really need the foil and it came out nicely! Next time I’ll bulk it up a bit with more spices and peppers, onions, etc, but this was an easy and simple meal just as the recipe intended!
Great recipe! I did modify it a bit. I added diced onion, minced garlic, and some bacon pieces. I also modified the cooking time because I used a smaller, but deeper dish. But still came out excellent (really just have to watch to make sure the eggs cook fully). This will quickly become a go-to meal, but it’s just so good.
Can this made than frozen? I need to make it and we will not serve for 2-3 days
Can you use potatoes O’Brien in place of the shredded hashbrown potatoes?
We haven’t tested it but think it would work. We’d love to know how it goes if you do give it a try!
O’Brien potatoes worked fine!!! Love this recipe!
I’m excited to try, but I want to prep ahead of time and warm later. What’s the best way to re-heat? Thanks
The microwave is easiest! Or, you can bake at 350 degrees until warmed through about 20 to 25 minutes. Cover the dish with foil if the top begins to brown too quickly. We hope you enjoy!
Delicious!!! Easy to make and oh so tasty! My husband and I love this casserole!
We’re so happy to hear this! Thank you for trying it out, Tyffani!
Can you make ahead and bake next day
Can almond milk be used rather than cows milk?
Feel free to test this out but I don’t see why not!
I added an extra egg and used 1 3/4 c milk and tator tots . Was way less soupy it was perfect! Now when i reheat there’s no liquid! Much much better!
Thank you for the feedback, Kimberly!
Yes, I am having trouble with it being so runny.
I tweaked this recipe a little. I added some onion powder, and some adobo to the eggs. I also let it get mostly cooked then I added cut up small pieces of biscuits on top. It was really good! Thanks for sharing your recipe
We’ll have to try your version! We’re so glad you enjoyed it, Joanna!
This is a fantastic recipe, wonderfully versatile, and a crowd pleaser. I make it quite often when I have company to feed! I follow the basics, but have added kale, spinach, mushrooms, green onions, peppers, or salsa. Depending what I have on hand.
Thank you, Jenn! We’re so glad you enjoy this recipe as much as we do. 😊 Do you have any particular favorite combinations of ingredients?
