Begin by preheating your oven to 350℉ (175℃).
In a large mixing bowl, combine all the ingredients: almond flour, salt, avocado oil (or melted butter), egg, grated cheddar cheese, and chopped chives. Stir everything together thoroughly with a spoon or spatula until a well-mixed dough forms. You can also use a stand mixer for quick blending.
Shape the dough into a cohesive ball.
Gently press the dough into a disk shape and carefully place it into your 9-inch pie pan or tart pan.
Using your fingers or the bottom of a mini saucepan/cup, evenly press the dough across the bottom and up the sides of the pan, ensuring a consistent thickness.
For a pretty finish, you can use your pointer finger to create decorative fluted edges around the rim of the crust, if desired.
Lightly prick the bottom of the pie crust several times with a fork. This helps prevent air bubbles from forming during baking. (Alternatively, you can skip the fork and gently flatten any bubbles with a mini saucepan or glass after the crust bakes).
Bake the savory crust for 10-12 minutes until it turns a light golden brown. If you plan to add a filling and bake the pie further, blind bake the crust for about 9 minutes to ensure the bottom sets perfectly.
Healthy Tip: To prevent the edges from over-browning, you can cover them with a pie shield or aluminum foil during baking.
