# Instructions:
01 -
Preheat the oven to 325°F. In a medium bowl, whisk together almond flour, garlic powder, and salt. Stir in melted butter until the dough resembles coarse crumbs. Press the dough into a 9-inch glass or ceramic pie pan, forming an even layer along the bottom and up the sides. Use a flat-bottomed glass or measuring cup to smooth the crust bottom, crimp the edges, and prick the base all over with a fork. Bake for 10-12 minutes, or until slightly puffed and starting to brown. Remove from the oven and allow to cool.

In a large skillet over medium-low heat, melt the butter. Add the sliced onions and season with salt and pepper. Cook, stirring frequently, for 15-20 minutes or until soft and caramelized, ensuring they do not become crispy.

Fill the cooled quiche crust with the caramelized onions and half of the grated Gruyére. In a large bowl, whisk together the eggs, heavy cream, salt, and pepper. Pour the egg mixture evenly over the onions and cheese, then top with the remaining grated Gruyére.

Bake the assembled quiche at 325°F for 35-40 minutes, or until the filling is just set in the center. Remove from the oven and allow to cool for 15 minutes before slicing and serving.
