How To Make A Breakfast Casserole With Sausage and Hash Browns 

This hash brown breakfast casserole is almost TOO easy.

Step One: Simply start by browning your lean Italian turkey sausage, drain and then add in the bell pepper, onion and garlic to cook until soft. Once that’s cooked, stir in the thawed and drained spinach.

Step two: While the sausage mixture is cooking, you can be whisking the eggs with the milk, basil, salt and pepper.

Step three: Mix that yummy seasoned sausage with thawed hash browns in a 9×13 glass baking dish that has been sprayed with nonstick cooking spray.

Step four: Last step! Pour the egg mixture  over the sausage and potatoes in the baking dish. You can either cover with foil and store in the fridge overnight or cover with foil and bake immediately. Bake for 1 hour at 350ºF, uncover and bake for another 15 minutes and until center is set. Allow casserole to cool for about 5-10 minutes before slicing into squares.

My family often enjoys this meal with a side salad for brinner (breakfast for dinner). You can prepare it on Sunday night and then when you get home from work on Monday, just pop it in the oven. So easy!

Can This Sausage Egg Breakfast Casserole Be Made The Night Before?

If you are looking for an overnight hash brown breakfast casserole, this recipe is perfect for you!

Many times, I’ve made this breakfast casserole the night before baking. Just assemble as you would, cover and refrigerate overnight. You may need to add an extra 10-15 minutes to the total baking time in the morning.

Easy-peasy and perfect for when you are entertaining and especially wonderful to enjoy Christmas morning!

Is This Hash Brown Breakfast Casserole Paleo and Whole30 Compliant?

This sausage hash brown casserole can easily be made Whole30 compliant. There are just a few things you need to watch out for.

  • Make sure the sausage is gluten-free. I love organic chicken or turkey sausage because there are very few fillers used and it will be easier to find a brand that is gluten-free and MSG free.
  • Check that the hash browns are gluten-free. You will notice some brands contain gluten and ingredients that would not be Whole30 approved. Another option is to make your own hash browns.

Bottom line: If you are serving this breakfast dish to gluten-free guests be sure to carefully read both your sausage and hash brown ingredient list.

Can This Cheese And Egg Hash Brown Breakfast Casserole Be Made Without Sausage?

Turkey or chicken sausage are my favorite options for this casserole, but any breakfast sausage will work. If you don’t like sausage, omit meat altogether or use diced leftover ham or crisped up bacon.

Other Tips For Making This Breakfast Casserole:

  • If you would like to make your own hash browns for this dish, which I often do because it is so easy, here is a great step by step recipe for homemade hashbrowns from Country Cleaver.
  • I’ve use shredded hash browns and cubed hash browns for this recipe. Even a variety with peppers and onions is a great choice.
  • Are you’re a cheese lover? Try adding sharp cheddar over the top of the sausage breakfast casserole, Gruyere, Swiss, Gouda, or Mozzarella would all be tasty choices.
  • Make sure you squeeze the water out of your thawed spinach, otherwise you’ll end up with a watery mess! If you do forget, just sauté the veggie mixture longer or until the water is evaporated.
  • To FREEZE this breakfast casserole for later use, bake and cool before freezing in a freezer safe pan (like a foil disposable pan). Wrap well in foil and freeze. Defrost in fridge the night before you’re planning to eat and then cook for 30 minutes at 350º or until warmed through.
  • This recipe can easily be doubled to feed a crowd.
