Hashbrown Breakfast Casserole Ingredients & Substitutions

Ingredients for hashbrown breakfast casserole.

  • Ground Sausage: Use regular pork breakfast sausage.
  • Red Bell Pepper: Or you can use yellow, orange or green bell pepper. If you want more spice use a jalapeño pepper.
  • Seasoned Salt: We use Redmond Seasoned Salt, which is a combination of salt, onion, coriander, mustard, black pepper, paprika, celery salt, turmeric and parsley. Any other brand of seasoned salt can be used. Or you can make a homemade seasoned salt blend.
  • Cheese: Grated cheddar cheese or other melting cheese of your choice.
  • Heavy Cream & Milk: 2 % or whole milk are good options, you can also use half-and-half in place of combining milk and cream. Or use a dairy free option if needed.

How to Make Hashbrown Breakfast Casserole

To begin, preheat your oven to 350 degrees F. Grease a 9×13 baking dish and set it aside. 

Melt the butter in a large skillet over medium heat. Add the frozen hashbrowns, and cook for 10 minutes, stirring occasionally to get crispy on all sides. Remove the hashbrowns to the prepared baking dish.

Next, in the same skillet add the ground sausage and cook over medium heat, breaking it up as it cooks. Cook while stirring, until meat is starting to brown. Add the bell pepper and onion to cook with the sausage. 

Once the sausage is browned and no longer pink and the veggies are softened, add the garlic and cook an additional 30 seconds.

How Can I cut the recipe in half?

Make a smaller version of this dish by cutting the ingredients in half and baking in a smaller, square baking dish (9×9). The bake time should be the same.
