1. Prepare the Crust: First, preheat your oven to 325°F (160°C). In a medium bowl, simply whisk together the almond flour, garlic powder, and salt. Then, stir in the melted butter until the mixture looks like coarse crumbs.
2. Form the Base: Gently press this crumbly dough into a 9-inch glass or ceramic pie pan. Make sure it's pressed firmly across the bottom and up the sides. For a really even base, you can use the bottom of a flat glass or measuring cup.
3. Par-bake for Crispness: Crimp the edges of your crust nicely, then lightly prick the bottom all over with a fork. Bake it for 10 to 12 minutes, just until it starts to look lightly golden. Take it out and let it cool while you get the filling ready. This step helps prevent a soggy crust!
4. Add the Veggies & Cheese: Once the crust is cooled, evenly scatter the chopped broccoli and the cubed cheddar cheese over the bottom of it.
5. Mix the Custard: In a large bowl, whisk together the eggs, heavy cream, minced garlic, salt, and pepper until well combined. This creamy mixture is your quiche filling!
6. Pour & Bake: Carefully pour the egg mixture over the broccoli and cheese in the crust. Sprinkle the remaining ¼ cup of shredded cheddar cheese over the top. Bake for 35 to 40 minutes, or until the center feels firm and set. Remove from the oven and let it cool for about 15 minutes before slicing and serving. Enjoy your delicious, healthy quiche!
