In a mixing bowl, whisk together the flour and salt until combined. In a separate bowl, beat the egg lightly, then add the milk, agave syrup, melted ghee, and vanilla extract.
Mix until well combined. Gradually pour the wet ingredients into the dry ingredients, whisking continuously until you have a smooth batter. Make sure there are no lumps.
Cover the bowl with plastic wrap or a kitchen towel and let the batter rest in the refrigerator for at least 30 minutes. This will allow the flour to hydrate and the flavors to meld, resulting in softer, more flavorful crepes.
Heat a non-stick skillet or crepe pan over medium heat. Lightly grease the skillet with a small amount of butter or oil. Once the skillet is hot, pour about 1/4 cup of batter into the center of the skillet. Immediately tilt and rotate the skillet to spread the batter evenly into a thin circle. Cook the crepe for about 1-2 minutes, or until the edges start to lightly brown and lift away from the skillet. Use a spatula to carefully flip the crepe and cook for an additional 1 minute on the other side, or until lightly golden.
Transfer the cooked crepe to a plate and cover with a clean kitchen towel to keep warm while you cook the remaining crepes. Repeat this process with the remaining batter.
Fill them with your favorite sweet or savory fillings (such as fresh fruit, Nutella, jam, whipped cream, cheese, ham, or sautéed vegetables).
Enjoy!
