We have overnight guests throughout the year and holidays as friends and family come from out of town and spend the night. With that being the case, serving breakfast has become an important part of entertaining!

I’ve been making this breakfast dish for over 20 years and it’s always a favorite!

Why You’ll Love It

  • Hearty and meaty. This is not an eggy dish. Hash browns and sausage are the stars, with enough cheese to make it rich and satisfying. You can even serve it for dinner!
  • Prep ahead. It’s simple to put together the night before, place in the refrigerator, and put into the oven the next morning.
  • Versatile. I’ve used the same recipe with diced Canadian bacon instead of sausage for an even quicker preparation. You can also try it with pepper jack cheese for a bit of heat, and use cubed hash browns instead of shredded.
  • Delicious! The ingredients are pretty basic but the combination is superb. Take this to church potlucks, serve it for a bridal shower brunch, or make it for weekend gatherings.

Ingredients

  • Frozen hash browns. I like the texture of the shredded ones for this, plus they cook a little quicker. I recommend thawing them in the fridge overnight so they’re easy to work with.
  • Ground breakfast sausage. I use regular flavor you buy in the tube – usually Jimmy Dean or Bob Evans brand. I don’t recommend using flavored varieties like sage or maple.
  • Sharp cheddar cheese. Buy a block and shred it yourself for best flavor and texture.
  • Evaporated milk. This is an easy pantry ingredient to keep around for when you need it. It’s great because regular milk is perishable so you might not have it when you need it.
  • Egg. You only need one egg to this recipe, to help bind everything together.
  • Ranch Dressing & Seasoning Mix. This adds great flavor! Go ahead and grab a 1-ounce packet so you have enough. If you only have the 0.4-once size, use it all.
  • Dry onion flakes. This pantry staple adds flavor without cutting or pre-cooking onions.

How to Make It

See full instructions in the recipe card below.

  1. Cook the sausage so it’s no longer pink.
  2. Layer the ingredients in the baking dish.
  3. Cover with foil and refrigerate until ready to cook.
  4. Put the dish in a cold oven and let it heat up with the oven so the dish doesn’t shatter from the temperature shock. Once the oven has reached 350, cook as directed.

PARTY TIP: For overnight guests, prepare the casserole, cover with foil, and place in refrigerator over night. Leave a sticky note with directions on top of the casserole so whoever wakes up first can put it in the oven.

Serve this with fresh fruit and spiced muffins with oatmeal topping for a well rounded menu. Sip on a yummy bloody Mary or pear mimosa to make it a celebration!

  1. Do I have to use evaporated milk? Why evaporated milk? Can I substitute? Just wondering because I’ve never used that ingredient before and would like to try this casserole.

    1. Melissa, the EM makes the dish more creamy and rich. Regular milk has a higher water content that will not give you the same results.

  2. Crock Pot Mac N Cheese and deviled eggs! Everyone always loves it! 🙂 For dessert a simple chocolate creme pie! Happy Thanksgiving!

  3. My go-to dish for the holidays is cornbread stuffing made with fresh pecans from my father’s yard.

  4. Chicken and rice casserole for me! I’ve got it memorizes and try to keep the ingredients stocked as a just-in-case meal!

  5. My go-to dish is an ooey-gooey butter cake! Its absolutely delicious but pretty unhealthy (I’m sure you could tell by the name!)

  6. My go to dish is lasagna! This looks awesome! Could you divide and freeze? Would love to make this for brunches or dinner!

  7. My go to holiday dish is a sausage, cream cheese, egg and hash brown with rotel hash mix that I make in my crockpot – it is so easy and so delicious!

  8. My go-to dish to serve holiday guests is banana bread – everyone loves it, it’s great anytime – as a snack or as an easy breakfast with yogurt and fruit, and it’s easy to bake and keep on hand!

  9. I set up a taco bar. I have meat, chicken and veggie and lay out all the toppings. Everyone makes their own.

  10. I love to make a big pot of potatoe soup with grilled ham and cheese sandwiches on sourdough bread. Everyone loves sitting around the table eatting and talking. We finish off with a pie and coffee.

  11. Pastries, like croissants and doughnuts. They are a treat we don’t have often and people can easily grab them whenever they wake up!
