Preheat your oven to 325°F (163°C). Line a baking sheet with parchment paper.
In a large bowl, mix together the shredded coconut, sweetened condensed milk, and vanilla extract until fully combined.
In a separate bowl, beat the egg whites and salt with an electric mixer until stiff peaks form.
Gently fold the beaten egg whites into the coconut mixture using a spatula.
Scoop tablespoon-sized mounds of the batter onto the prepared baking sheet, spacing them about 1 inch apart.
Bake for 18-20 minutes, or until the macaroons are golden brown around the edges.
Remove from the oven and let cool completely on the baking sheet before serving or storing.
