Ingredients Needed

  • Ground pork sausage – Swap for turkey sausage, Italian sausage, chicken breakfast sausage, or smoked sausage as well. Spicy Jimmy Dean is my favorite!
  • Hash browns – Use frozen hash browns to save time. Or swap with tater tots or refrigerated shredded hash browns.
  • Sharp cheddar cheese – If you can’t find sharp, try using a mild cheddar cheese or shredded cheese of your choice. 
  • Sour cream – Substitute for Greek yogurt or room temperature cream cheese as well. 
  • Milk or half & half – For a thicker and creamier casserole, choose half and half.
  • Pantry items – Onion powder, garlic powder, salt, black pepper, large eggs.

This is one of my favorite recipes for an overnight breakfast casserole because it’s extremely easy to make ahead and serve when you’re ready.

The first step is to make the recipe according to the instructions. If you are planning on serving this casserole within a few days, cover the baking dish tightly with plastic wrap, before removing to bake for a little more time than listed in the directions.

Can I Make My Own Hashbrowns?

The best way to step up this sausage casserole recipe is to make your own hash browns, rather than using frozen. For this, I use shredded brown potatoes and start with two separate bowls.

After placing shredded potatoes in a bowl of cold water and washing off the starch, move them to another bowl with clean water. After a second rinse, drain as much of the water as possible and pat dry with paper towels. Cook small pieces in a skillet until crispy, making sure to flip so you brown both sides. Serve and enjoy homemade tasty hash browns in your delicious breakfast casserole!

Best Casserole Tips

  • To pack in more veggies, try adding in red bell pepper or green pepper to the recipe.
  • Use finely chopped onion instead of onion powder.
  • For a little kick, try adding red pepper flakes or hot sauce to the top of your egg casserole breakfast bake.
  • If your cheese on top starts to burn, cook covered with aluminum foil for the majority of the time and remove for the last 10 minutes.
  • Since the cheese topping is usually the best part of this delicious casserole, make sure that you’re adding plenty. When reheating, add on a little extra cheese to top off this sausage breakfast casserole.
