Place sausage on baking sheet, leaving space between each sausage.
Bake for 20-25 minutes until fully cooked through, flipping once halfway through cook time.
Remove from oven and serve hot.
Notes
You can select any number of sausages to cook at one time. Just make certain to leave space between each sausage.
Parchment paper makes for easier cleanup. You can bake without if you prefer.
If cooking a large number of sausages, you may want to use two baking sheets. Rotate the location of baking sheets in the oven halfway through cooking time. This will help ensure even cooking.
Sausages are fully cooked when the internal temperature reaches 165°F.
