If Quiche Florentine sounds intimidating, I promise it just means spinach. This quiche is loaded with sautéed spinach, garlic, and SO much Gruyère in a flaky pie crust, and it's one of those recipes that looks like you spent all morning on it. Grab a store-bought crust and you're looking at about 15 minutes of real work.
Place and shape the pie crust into a 9-inch pie dish and crimp the edges. Poke holes into the bottom using the tines of a fork. Place a piece of parchment paper into the pie crust and fill with either pie weights or dried beans. Par-bake the crust for 15 minutes.

Add the butter to a large skillet over medium heat. Once melted, add the onion and saute for 3-4 minutes, or until translucent. Mix in the garlic and continue cooking for another 30 seconds, or until fragrant. Add spinach and saute for 2-3 minutes more, or until wilted.
Whisk together the eggs, cream, salt, pepper, paprika, and nutmeg in a large bowl.
4 large eggs, 1 ¼ cups heavy cream, ¾ teaspoon salt, ¼ teaspoon black pepper, ¼ teaspoon paprika, ⅛ teaspoon nutmeg
Sprinkle ¾ cup of the cheese into the bottom of the par-baked pie crust, then add the spinach, pour in the eggs, and sprinkle with the remaining cheese. Mix everything together lightly using a fork.
1 cup Gruyere or Swiss cheese
Bake at 375 for 40-45 minutes or until the center just barely jiggles.
Allow to rest for 10-20 minutes before slicing in and serving with fresh parsley, if desired.

Notes
Storage: Pop leftover quiche in an airtight container or wrap tightly with plastic wrap. Keeps in the fridge for 3 to 4 days.
Freezing: Freeze baked quiche (cooled completely) wrapped in plastic wrap and foil for up to 2 to 3 months. The crust won't be quite as flaky after thawing and the filling texture changes slightly, but it still reheats well. Thaw in the fridge overnight.
Reheating: Warm slices in the oven at 325 degrees for 10 to 15 minutes. Microwave works but the crust won't stay as crispy.
Make ahead: Bake the quiche completely, let it cool, then refrigerate. You can also prep the pie crust a couple of days ahead of time.
Pie crust: Store-bought works great here. Just make sure to par-bake it with dry beans or pie weights before adding the filling.
Spinach: Use fresh spinach and sauté it first to remove excess moisture. If using frozen, thaw it completely and squeeze out ALL the water before adding to the filling.
Room temp eggs: Pull eggs out of the fridge about 20 minutes before starting. Room temp eggs blend more smoothly with the cream.
