Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a mixing bowl, combine ground sausage, cheddar cheese, Parmesan cheese, almond flour, egg, baking powder, garlic powder, onion powder, salt, and pepper.
Mix the ingredients until well combined.
Shape the mixture into small balls and place them on the prepared baking sheet.
Bake for about 18-20 minutes, or until the sausage balls are golden brown and cooked through.
Allow them to cool slightly before serving.
