Preheat your oven to 375°F and lightly grease a 6-inch oven-safe baking dish or skillet with the ghee.
Slice the peach into thin, uniform wedges and arrange them in a decorative circular pattern at the bottom of the dish.
In a blender or medium mixing bowl, combine the eggs, egg whites, Greek yogurt, almond flour, vanilla extract, cinnamon, maple syrup, and sea salt.
Whisk or blend the mixture until it is completely smooth and slightly frothy to ensure a light texture.
Carefully pour the custard batter over the arranged peach slices, being careful not to disturb their placement.
Bake for 25 to 30 minutes until the clafoutis has puffed up and the center is set with a slight jiggle.
Remove from the oven and let it rest for 5 minutes to firm up before slicing into wedges and serving warm.
