Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking.

In a large mixing bowl, combine almond flour, grated parmesan cheese, garlic powder, onion powder, and salt. Stir until evenly mixed.

Crack the egg into the bowl and add olive oil or melted butter. Mix until a dough forms. The dough should be firm but pliable, not sticky or crumbly.

Place the dough between two sheets of parchment paper. Use a rolling pin to roll it out evenly to about ⅛-inch thickness. The thinner the dough, the crispier the crackers.

Remove the top parchment paper. Use a knife or pizza cutter to slice the dough into squares or rectangles. Dock the crackers with a fork if desired to prevent puffing.

Transfer the baking sheet to the oven and bake for 12–18 minutes, or until the edges are golden brown. Baking time may vary depending on thickness.

Remove from the oven and allow the crackers to cool completely on the baking sheet. They will continue to crisp up as they cool.
