Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.

Combine the ground sausage, shredded cheddar cheese, Bisquick mix, garlic powder, onion powder, black pepper, and parsley in a large bowl. Stir until blended well.

Add the milk gradually while mixing. Stir until the mixture reaches a thick consistency that holds together well.

Shape the mixture into 1-inch balls and place them on the prepared baking sheet.

Bake in the preheated oven for 20-25 minutes, until golden brown and aromatic.

Cool the sausage balls slightly before serving.
