Step 5: Bake the Casserole

Cover the dish with foil and bake the casserole in a 350 degree F oven for 50 minutes. Then remove the cover and return the dish to the oven for about 10-15 more minutes, or until the eggs are set. Let the casserole stand for a few minutes before slicing and serving!

Preparation and Storage Tips:

  • This easy breakfast casserole with sausage is perfect for entertaining because you can prepare it in advance. The overnight breakfast casserole can be assembled up to 24 hours ahead of time, and then baked according to recipe instructions. Allow the dish to sit on the counter and come to room temperature while the oven preheats.
  • Leftover casserole will keep in the refrigerator for 3-4 days.
  • To freeze the casserole: Bake in a freezer safe pan (like a foil disposable pan) and cool completely. Wrap well in foil and freeze for up to 3 months. Defrost in the fridge the night before you plan to eat the casserole. Reheat the casserole in a 350 degree F oven for about 30 minutes, or until warmed through. You can also reheat individual slices in the microwave for about 1 minute.
  • This casserole is an easy breakfast or brunch dish, but it’s also a convenient weeknight dinner that you can prep ahead.

Cook’s Tips and Recipe Variations:

  • I prefer using whole milk or cream for this recipe. I don’t recommend low-fat or fat-free milk, since the fat in the milk or cream helps create the rich egg custard for the dish.
  • Substitute other cheeses for the cheddar. For instance, try Monterey Jack, Pepper Jack, Swiss or Gruyere.
  • Add diced, sautéed vegetables to the casserole. You can use mushrooms, onion and bell peppers, for example. A can or two of chopped green chiles would also be delicious!
  • Make the breakfast casserole with bacon or ham instead of the sausage. You will need about 2 – 2.5 cups of diced ham or cooked, crumbled bacon.
  • Give the dish some “kick” by using spicy sausage.

  1. these are my favorite types of recipes – eggy/cheesy/potato-y! I love that you can make this and have it for breakfast for the rest of the week. Plus its so simple! Pinning for later 🙂

      1. 5 stars
        This is delicious. I used bacon. This is the only recipe I make for a hash brown casserole. I like the cheddar cheese. You don’t need all those other cheeses. And I don’t use vegetables either. Vegetables are good for omelets. I love it just the way it is.

    1. 5 stars
      I am a egg and potatoes kind of girl. Potatoes are my downfall. Would appreciate any frozen potato recipes

    Such a great idea, Blair! So versatile and easy. You are so creative with your recipes. I need to come to your house for a week and get my brain re-energized, lol.
    Seems we all need to take meal planning seriously these days. It’s the only way to survive it all!
    Sharing 🙂

    1. Thanks, Robyn! That’s right — you can have it for dinner one night and then enjoy the leftovers for breakfast all week long! 🙂

    1. Thank you, friend! You just can’t go wrong with these ingredients, right? They seem to make everyone happy! 🙂

    When I googled this recipe, I got about 20 different ones. I chose this one, and hit the jackpot! I have had 10 adult kids here for the Thanksgiving weekend. I made this AWESOME recipe, and the made me make it the next morning also. Don’t look anywhere else, this is the one!!!! For some reason, the rating stars below won’t take my ratio, but it’s definitely a 5 star recipe.

  4. Says it can be made way in advance….can I prepare it the night before and put it in the fridge overnight? Bake it in the morning?

  5. 5 stars
    I’ve made this casserole a few times. It’s very good! When I make it though I also use a large can odd green chilies, chopped. You can add them right in with the potatoes and sausage. Wonderful!

  6. I prepared the Sausage Hash Brown Casserole using your recipe. The end result: tasted bland and was dry. Where did I go wrong?

    1. Hi, Shari! I have never tried baking any of these dishes in the microwave, so it would definitely be trial and error to get the timing correct. That said, I think it would probably work fine if you brown the sausage in a skillet first.
