Step-by-Step Instructions for Hashbrown Breakfast Casserole

Preheat the Oven

Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking pan.

Cook the Sausage

Heat a large skillet over medium-high heat. Add the ground pork sausage and cook, breaking it up with a spoon, until it’s browned and no longer pink. Once cooked, drain any excess fat and set the sausage aside.

Assemble the Casserole

In the prepared baking dish, evenly layer the thawed hashbrowns, cooked sausage, diced onions, red and green bell peppers, and 1 ½ cups of shredded sharp cheddar cheese. Gently mix the ingredients together in the pan to ensure even distribution.

Prepare the Egg Mixture

In a large bowl, whisk together the eggs, evaporated milk, salt, black pepper, garlic powder, and Italian seasoning. Beat the mixture well until everything is fully combined and smooth.

Combine and Bake

Pour the egg mixture over the hashbrown mixture, making sure to coat everything evenly. Sprinkle the remaining ½ cup of shredded cheddar cheese on top of the casserole.

Refrigerate or Bake

You can either bake the casserole immediately or, for added convenience, cover it with foil and refrigerate it overnight. If baking immediately, ucover the dish with foil and bake in the preheated oven for 50-60 minutes, or until the casserole is set and cooked through, with a golden, slightly crispy top.

Serve and Enjoy

Once baked, remove the casserole from the oven and let it cool for a few minutes before serving. It pairs wonderfully with fresh fruit or a side of toast, making for a complete breakfast.

Storage and Serving

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, simply cover the casserole with foil and warm it in the oven at 350°F for 15-20 minutes until heated through.

This casserole also freezes well! If you have leftovers or want to prepare ahead of time, freeze individual portions for up to 2 months. To reheat from frozen, bake at 350°F for about 30-40 minutes.

Tips for Success

• Use Thawed Hashbrowns: If using frozen hashbrowns, make sure they’re fully thawed and drained before adding them to the casserole. This helps avoid excess moisture in the dish.
• Customize Your Cheese: While sharp cheddar is a great choice, feel free to use other cheeses such as Monterey Jack, mozzarella, or a cheese blend for variety.
• Don’t Overmix: When mixing the ingredients, be sure not to overmix the hashbrowns and sausage. You want a gentle stir to ensure everything is evenly distributed without mashing the potatoes.

Variations

• Vegetarian Version: Skip the sausage and add more vegetables, such as mushrooms, spinach, or zucchini, for a meatless option.
• Spicy Sausage Casserole: For a bit of heat, use spicy breakfast sausage and sprinkle some red pepper flakes or hot sauce on top before serving.
• Loaded Hashbrowns: Add extra toppings like crumbled bacon, diced tomatoes, or sour cream for a loaded version of the casserole.

Wrapping it up
