Easily feed a crowd with this 5-minute prep breakfast potato egg casserole – a family favorite and the perfect make-ahead meal!
Prepped in 5!
We have breakfast for dinner at least ONCE a week because we love breakfast that much! Breakfast casseroles are one of our go-to’s because they’re so simple and today’s recipe for potato egg casserole is one of our favorites.
We first made this for a holiday breakfast years ago and have had it on repeat since. It’s filled with cheesy potatoes, eggs and sausage and is so delicious and simple (it’s prepped in 5 minutes!)
As with most casseroles, this is perfect for making ahead of time for an easy morning (think holidays or busy weekends). Even so, it’s simple the morning of – just mix and bake and it’s ready in 40 minutes!
Pair it with a sweet casserole like Coffee Cake or Cinnamon Bites for a complete meal.
WHY WE LOVE IT:
- Filling. This particular casserole has potatoes, eggs, sausage, and cheese – some of our favorite hearty breakfast or brunch ingredients.
- For an easy morning. This egg bake is prepped in 5 minutes and on the table in 40 for a less-fuss way to start your day.
- Prep the night before. Store in the fridge or freezer until you’re ready to bake – perfect for holiday mornings!
Ingredients
PREP TIME: 5 minutes
COOK TIME: 35 minutes
- 8 large eggs
- ½ cup milk, room temperature
- 1 (20-ounce) bag of frozen diced hash browns, thawed – To use fresh potatoes, peel and dice 20 ounces of russet potatoes – do not soak (the starch will thicken the casserole).
- 9-10 ounces precooked Italian sausage – You can brown raw Italian sausage in a skillet before adding the recipe.
- salt and pepper, to taste
- 1½ cups shredded mild cheddar cheese, divided – Substitute or combine it with Swiss cheese, pepper jack cheese, or Colby Cheese.

Flavor Variations
- MEXICAN. Add chopped peppers and use Mexican blend cheese.
- MEAT LOVERS. Add cooked bacon along with the sausage.
- VEGGIE. Replace meat with a cup of chopped spinach, mushrooms, zucchini, red bell pepper, or broccoli florets. Sauté veggies in a large skillet before adding.

Cant do recipe for all the ads popping up
Only 7oz of cheese? Is the recipe correct on that? It calls for starting with 1 cup (8oz), and reserving the rest for topping.
Thanks for catching that. We’ll get that post updated!
Delicious! I made it the night before and added some diced red and green pepper pieces for color.
Thanks for sharing what you did. I bet it looked and tasted great with those additions!
How can I use real potatoes instead of frozen?
Yes, absolutely! Just make sure they are pre-cooked. Leftover baked potatoes are a great option if not using the frozen hash browns.
This looks amazing!!! Is it gluten free by chance? My new daughter in law cannot eat gluten. 😊🤞
The recipe was not created as a gluten-free recipe, but you could certainly tweak anything in it that she couldn’t eat to make it work for her. 🙂
Delicious! I’ve tried a few variations of this recipe over the years and this is my favorite. I love it for its simplicity and deliciousness. We just ate it for Christmas breakfast and everyone loved it. The amount was perfect for a family of 4 and we even have some leftovers.
Printing the recipe right now so I won’t forget where I got from 🙂
Delicious cheesy goodness! This will be a go to!
This is my families favorite breakfast dishes. FABULOUS!!!!!!
We loved this! So easy and so filling. Perfect for Christmas morning.
I loved this recipe! It was so easy, and so delicious. It has to perfect ratio of sausage to egg to potato.
