1-First step: heat the oven and prep the pan Preheat your oven to 425°F. Coat a 9-inch pie plate with non-stick cooking spray so the crust releases easily later. This little step saves you from messy slicing and helps the potato crust keep its shape. If you are making this for brunch guests or a holiday meal, you can also set out your serving platter now so everything is ready when the quiche cools.

2-Second step: make the hash brown crust In a large bowl, toss the 3 cups of raw shredded potatoes with the melted unsalted butter. Season the mixture with salt and pepper to taste. Then press the potatoes firmly into the pie plate, making sure the layer covers the bottom and sides as evenly as possible. Firm pressing is important because it helps the crust bake into one sturdy shell instead of falling apart. Bake the crust for 25 minutes at 425°F until it starts turning golden and crisp around the edges. The crust should look set before you add the filling.

3-Third step: cook the sausage While the crust bakes, place the 8 ounces of seasoned Italian pork sausage in a skillet over medium-high heat. Cook it until no pink remains, which usually takes about 5 minutes. Stir and break it up as it cooks so you get small, even pieces in every bite. Then set it aside. If you want to add vegetables, this is a great time to do it. Bell peppers, mushrooms, or asparagus can be cooked quickly in the same pan. You can also toss in spinach or kale with the sausage and let it wilt for 3 to 5 minutes. That gives this potato crust quiche extra color and makes it a little more filling.

4-Fourth step: mix the custard filling Reduce the oven temperature to 375°F. In the same bowl you used for the sausage, whisk together the 6 large eggs, 1/4 cup heavy cream, 1 cup shredded cheddar cheese, 1 cup shredded Monterey jack cheese, and 2 finely chopped scallions. Season again with salt and pepper. Once the mixture looks well blended, stir in the cooked sausage. The filling should look thick, creamy, and packed with flavor. This is the part that gives the hash brown crusted quiche recipe its rich, satisfying center.

5-Fifth step: assemble and bake Pour the filling into the baked potato crust. Use a spoon to spread the sausage and cheese evenly so every slice gets a good mix. Bake at 375°F for about 30 minutes, or until the center is set and the top looks lightly golden. If you are not sure whether it is done, give the pan a gentle shake. The center should have just a slight wiggle, not a sloshy movement. If needed, bake for a few more minutes. Every oven is a little different, so a quick check near the end helps a lot.

6-Final step: cool, slice, and serve Let the quiche cool slightly before cutting it into wedges. A short rest helps the filling settle and makes clean slices easier. Serve warm for breakfast, brunch, or even a simple dinner with salad or fruit on the side.
