Ingredients

• Frozen hash brown potatoes: Choose the shredded kind for a fluffy base and make sure to thaw them fully to prevent a soggy casserole
• Pork sausage: Mild or spicy both work The sausage brings a classic savory kick
• Small onion: Gives depth and sweetness Opt for yellow or white for the best flavor
• Eggs: The binder for the whole casserole Go for fresh eggs for better structure
• Milk: Helps the eggs set and creates a tender texture Whole or 2 percent works best
• Onion powder: Boosts the onion flavor even more Use a fresh container for boldness
• Garlic powder: Adds subtle warmth and fragrance
• Salt and black pepper: Season to taste Always use fresh ground pepper for the best finish
• Shredded cheddar cheese: Go for sharp cheddar for maximum cheesy flavor Grate your own if you can

Step-by-Step Instructions

Gather and Prepare Ingredients:

Start by pulling everything you need out of the fridge and pantry Set your frozen hash browns out early so they thaw completely This saves you a lot of mush later

Preheat Oven and Prepare Hash Browns:

Set your oven to 350 degrees Fahrenheit and give an eight inch square pan a generous coat of oil or spray Spread the thawed hash browns right into the bottom and press them out smoothly This makes a sturdy foundation that crisps up at the edges

Cook Sausage and Onion:

Set a large skillet on medium heat and crumble in the sausage Toss in diced onion right away Stir occasionally while the sausage browns and the onion softens in about ten minutes Scoop out any excess fat when done to keep things from feeling greasy

Prepare Egg Mixture:

Grab a large bowl and beat together the eggs milk onion powder garlic powder salt and pepper Blend until the eggs are fully broken up and everything is mixed The milk lightens up the eggs and lets them bake up fluffy

Assemble the Casserole:

Pour your egg mixture carefully over the hash browns letting it sink in Sprinkle half your shredded cheddar over the eggs for flavor in every bite Spread the cooked sausage and onion mix evenly over top Nestle the rest of the cheese across the surface Cover the whole pan tightly with foil to prevent drying

Bake and Finish:

Slide the casserole into your hot oven and let it bake for one hour Uncover take off the foil and keep baking for another ten to fifteen minutes until the cheese bubbles and the top turns golden Let it rest for several minutes out of the oven so you get perfect neat slices
