Cheesy Mashed Potato Egg Casserole ~ Perfect Breakfast or Brunch Casserole Loaded with Mashed Potatoes, Eggs, Cheese and Bacon! This Hearty Breakfast Recipe is Perfect for Entertaining!

You are going to think I’m a slightly odd duck when I tell you this, but breakfast…breakfast gets me excited you guys! It’s so backwards because I really hate getting up in the morning and I don’t make a big breakfast very often but I love it all the same. I especially love it when I serve it for dinner! Luckily for me my girls and hubs love it too.
The girls are always requesting eggs, pancakes, waffles etc. I think I might love serving it for dinner because I feel like I’m daring and on the edge. Yes, in my life that’s about as daring as I get!
Also, another daring point in my life was using mashed potatoes in a breakfast casserole. I usually opt of hash browns like 99% of other people but I went out on a limb and decided that mashed potatoes were going to happen.
You guys, it was epic! We’ve made this multiple times already and that’s saying a lot! We’ve also mixed things up and substituted the Simply Potatoes® Mashed Potatoes our for their Simply Potatoes® Garlic Mashed Potatoes. Amazing! If you are a garlic lover like me then you need to try this option too!
Plus, Easter is right around the corner! Can you believe it? If you are looking to keep your holiday meal simple this is your ticket! This recipe comes together in minutes so you can spend time with your guests instead of slaving over the meal in the kitchen. Sounds like a win right? I’m practicing #SimplyHolidays and making it real and simple!
One thing that is always stocked in my fridge is Simply Potatoes. Whether it’s their fabulous mashed potatoes, hash browns or diced potatoes they make my meal times way simpler.
Plus, I love that they are fresh and never frozen potatoes and made with real ingredients! I can either throw them in my favorite recipe or serve them up as a side dish. Either way it’s a win for this Mom! Make sure to check out their product page!
For this delicious Cheesy Mashed Potato Egg Casserole I dressed up our Simply Potatoes Traditional Mashed Potatoes! I love that it’s the perfect quick and easy breakfast or brunch recipe for your family or when you have guests plus it would be great for breakfast for dinner because it’s so hearty!

Stefano says
It smells great but I have had the same issue with the cook time. The eggs are completely runny after cooking for 1 hour at 350…I’m trying to raise the temp and just ended up mixing up the eggs to cook faster.
Brooke Kill says
Every oven cooks differently, just find the temp and time that works best for you!
Cate says
I was wondering, when replacing with homemade mash, what amount would be needed?
Lynn says
Don’t like packaged potatoes. Tastes too fake
Courtney says
Go ahead and make your mashed potatoes and then give it a try!
ALISHA says
I havnt eaten it yet. But my rating is not on taste. It’s on cook time. Says 20 mins on 350. I have a nice newer stove and it’s been in there for almost 40 mins and the eggs are still not cooked on top. I’m sure the recipe is good for taste because it’s looks very appetizing. Buy I don’t know how the cook time could be this off.
Courtney says
Shoot, we did not have this issue while testing this recipe. I hope the meal turned out to be delicious!
Mark says
Instant mashed potatoes? Instantly turned off.
Courtney says
You can sub homemade mashed potatoes if you’d like!
Sarah says
Mark is a rude troll commenting about instant potatoes. Courtney was sweet not to tell him to buzz off.
Courtney says
Thank you!
