Sausage Egg Cheese Casserole FAQs
A few reasons your breakfast casserole might be soggy:
Extra Liquid: Ensure you drain the sausage before adding it to mixture with other ingredients.
Egg Ratio: Make sure you have added the right number of eggs.
Frittata: Cooked on the stovetop and finished in the oven, a frittata is like an open-faced omelet. It's usually cooked in a skillet and doesn't involve layering ingredients like a casserole.
Egg Casserole: A casserole typically has the ingredients mixed or layered in a baking dish and is baked in the oven.
Whether to bake this sausage and egg casserole covered or uncovered depends on your preferences.
Uncovered: Allows the top to brown and get a little bit crisp. If the top browns too quickly, cover it with foil until the casserole is cooked through.
Covered: Helps retain moisture and prevents excessive browning. Remove the cover toward the end to allow browning if needed.

no salt, pepper, seasonings needed?
Nope! You are welcome to add them if you like though! We just let people do that as needed :)
Can you put everything in the casserole dish the night before and then pop in the oven in the morning?
Yes mam! Just make sure you keep it in the fridge! ????
Is the sausage in this recipe ground sausage which you pre cook?
Yes it is!
Hi...just came across your recipe on Pinterest and plan to try it this weekend. When you say "precooked" sausage what are you referring to...like Eckrich or Hillshire Farms smoked sausage? I was thinking of using breakfast roll pork sausage as in most breakfast casseroles I have made (though that is not precooked).
I just meant if it's not pre cooked, you should cook it BEFORE you add it to the casserole! So any kind should work just fine!
Thank you!
You're so welcome!
You can cook a lb. of sausage in the mircrowave . Break up sausage in microwave pan, cook 3 minutes, take out, drain grease, break up sausage some more, put back in micro for 21/2 more minutes or until cooked. Easy and I do all of my recipes that call for hamburger or sausage this way.
Genius!! Thanks so much for sharing!
Is there a substitute for the eggs?
Not that I know of, so sorry!
I needed a last minute breakfast/brunch casserole. I forgot I made the commitment of actually cooking. I googled and found your recipe. My contribution to the meal was the only empty bowl with people looking for more. FANTASTIC!!
Ah yay!!! I'm so glad to know you loved it! Thank you for coming back to share your experience, you totally made my day!!
OMG This was soooo goood! I halved the recipe to make myself breakfast for a week. Replaced the mushrooms with grated zucchini and added paprika and oregano. I used jerk sausage so it was a little bit spicy but...very awesome. I don't think its gonna last the week...
Oh my gosh those changes sound amazing!! Thanks so much for sharing and for coming back to report!!
Just made this and it is delicious. I used a pkg of Hillshire Farms turkey kielbasa, diced, for the sausage and added a tsp of salt to the egg mixture. Other than that I followed the recipe exactly. Baked longer than it called for but I expected that. Probably just over an hour. I don't think the kids would love it cause it's really dense with veggies but I was looking for a low carb, high protein and high veggie breakfast for myself that I can heat up throughout the week and this fit the bill. Hopefully I enjoy it as much reheated!
Tried this on Christmas morning and we were fighting over leftovers for 2 days. Really great recipe!
I tried this recipe last night and it was a hit with my future in-laws. It took me a little over an hour to bake it. What an easy & tasty go-to. Thank you for sharing!
I have cooked for over 70 minutes and still runny, was I supposed to add bread or something?
Can this be made the night before? I would like to prepare and or cook for the hubby when he goes to deer camp . He could cook it or just warm it up before they head out in the morning.
We reheat our leftovers and eat them the next day! It's not quite as good as right out of the oven (like most leftovers) but still really yummy!
Ps. Best wife award!
I am hoping to make this to bring to a party tomorrow morning. How many servings would you say it has? And has anyone ever cooked it the night before and heated it up in the morning?
The servings would depend on whether you were serving only this dish or there would be other sides as well. I usually cut it into 12 squares!
Could you add hashbrowns? and if so about how much would you think could be added?
Yes you can! I just add as many as will fit in my pan. Sometimes (depending on the hash brown) you will need to cook your mixture a little longer, just test to see!
Could you split this recipe up and freeze the other half for another time?
I'm not sure! I have never tried freezing it before, in sure you could find some tips online! Sometimes I do half the recipe though and just bake it in a smaller pan!
I AM SO HAPPY I HAD TO CAPS LOCK TO TYPE LOL OMGOSH I WAS HOPING AGAINST ALL HOPE THIS HAD NO POTATO IN IT AND YOU JUST EARNED MY EVERY LOVING AND FOLLOWING RESPECT <3 THANK YOU THANK YOU THANK YOU!!!!
Haha you totally just made my morning!!' I hope you LOVE it as much as I do!!!
I loveeee breakfast casseroles, and this looks amazing (esp because I love mushrooms.) Definitely pinning this for future use.
I love mushrooms too! They add so much, you'll love it!
Could you saute the MUSHROOMS with the sausage before adding to the mix?
This looks so delicious! Thanks so much for sharing :)
Of course :)!
YUM! You could also use Greek yogurt instead of sour cream .... mmmm... I think I need to go make breakfast. Must be hungry!
Great idea! I always have Greek yogurt on hand these days :)
This definitely does look like the world's best. I've done similar casseroles.. they're always good.. but I've never added sour cream. I bet that makes it extra awesome.
It really does add so much flavor! Thanks for commenting Cristina! Made my day :)
Could I use heavy cream in place of sour cream?
Yes it should work okay! I like to use this table for substitutions: https://www.eatbydate.com/substitutions/cream-substitutes/
