1-First Step: Preheat the oven and prepare 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 later. This small step helps the potato crust brown instead of sticking. While the oven heats, get your ingredients ready. Shred the potatoes if needed, chop the scallions, and have the sausage nearby. A little prep now makes the rest of the recipe move fast.

2-Second Step: Build and bake the hash brown crust In a large bowl, toss 3 cups raw shredded potatoes with 1/4 cup melted unsalted butter. Season with salt and pepper, then press the mixture firmly into the pie plate to form a crust. Pressing it in well helps the crust hold its shape and bake evenly. Bake the crust for about 25 minutes, or until it looks golden brown around the edges. If you are using pre-shredded potatoes, you can save time, but still make sure to pat them dry first if they seem wet. That helps the potato crust crisp up instead of steaming.

3-Third Step: Cook the sausage Lower the oven temperature to 375°F. In a skillet over medium-high heat, sauté 8 ounces seasoned Italian pork sausage for about 5 minutes, or until no pink remains. Break it up as it cooks so the pieces stay small and spread out well in the filling. Set the sausage aside to cool slightly. Cooling it a bit keeps the eggs from starting to set too early when you mix everything together. If you want to use spicy sausage or breakfast sausage, that works well too.

4-Fourth Step: Mix the egg filling In the same bowl you used for the crust mixture, whisk together 6 large eggs, 1/4 cup heavy cream, 1 cup shredded cheddar cheese, 1 cup shredded Monterey jack cheese, and 2 finely chopped scallions. Add a dash of salt and pepper. Then stir in the cooked sausage. The filling should look thick, creamy, and well mixed. The cheese will melt into the eggs as it bakes, giving the quiche a rich texture. If you want a slightly lighter version, half-and-half can stand in for the cream, but milk can make the filling too thin.

5-Fifth Step: Fill the crust and bake again Pour the sausage and egg mixture over the baked hash brown crust. Spread it out gently so the filling reaches the edges. Return the pie plate to the oven and bake at 375°F for about 30 minutes, or until the center is set. You will know the quiche is ready when the top looks golden, the middle no longer jiggles much, and a knife inserted near the center comes out mostly clean. If your oven runs hot, check it a few minutes early. If you are adding vegetables, cook them first so they do not release too much water into the filling.

6-Final Step: Rest, slice, and serve Let the quiche cool slightly before slicing. This short rest helps it firm up so you can cut clean wedges. Serve warm for brunch, breakfast, or even a simple dinner with a salad on the side.
