1-First step: Preheat and prep the pan Start by preheating your oven to 425°F. Coat a 9-inch pie plate with non-stick cooking spray so the crust releases easily after baking. This first step matters because the hot oven helps the potatoes start crisping right away. If you are cooking for a crowd, this is a great recipe to make in the morning while coffee is brewing. The prep is simple enough that busy parents and students can get it in the oven without stress.

2-Second step: Build the hash brown crust Place the raw shredded potatoes in a bowl and toss them with the melted unsalted butter. Season with salt and pepper to taste, then press the mixture firmly into the pie plate to form an even crust. Try to cover the bottom and work the potatoes slightly up the sides so the filling stays in place. Bake the crust for 25 minutes. You want it to look lightly golden and set before adding the filling. Using raw shredded potatoes gives the crust a better texture than using frozen hash browns that have too much moisture.

3-Third step: Cook the sausage While the crust bakes, place the seasoned Italian pork sausage in a skillet over medium-high heat. Sauté it for about 5 minutes, stirring and breaking it up as it cooks, until no pink remains. Then set it aside to cool slightly. This is a good moment to add extras if you want them. You can cook diced bell pepper, mushrooms, or asparagus with the sausage, or stir in baby spinach or kale at the end so it wilts gently. These small changes make the hash brown quiche feel new each time you serve it.

4-Fourth step: Mix the filling Lower the oven temperature to 375°F. In a large bowl, whisk together the eggs, heavy cream, cheddar cheese, Monterey Jack cheese, and chopped scallions. Once the sausage has cooled a bit, add it to the bowl and mix everything together. The filling should look thick, creamy, and well combined. If you want to make the flavor a little stronger, try spicy sausage or breakfast sausage instead of Italian sausage. If you prefer a softer custard, half-and-half can replace the cream.

5-Fifth step: Fill and bake the quiche Pour the sausage and egg mixture into the baked hash brown crust. Spread it out evenly so each slice gets a good balance of crust, cheese, sausage, and scallions. Return the pie plate to the oven and bake for about 30 minutes, or until the center is set. Keep an eye on the top during the last few minutes. If the edges brown too quickly, you can loosely tent the dish with foil. The goal is a filling that is just firm in the middle, not jiggly or wet.

6-Final step: Rest, slice, and serve Let the hash brown crusted quiche cool slightly before slicing. This short rest helps the filling settle, so you can cut clean wedges. Serve warm for brunch, lunch, or a cozy breakfast-for-dinner meal. Each serving gives you a hearty plate with a crisp potato base and a creamy egg filling. It is a great choice for home cooks who want something that looks impressive but is still simple to pull off.
