1. Preheat your oven to 400F.
2. Line a baking sheet or a shallow baking pan with parchment paper to keep the sausages from sticking to the bottom.
3. Arrange the sausages carefully on the baking sheet and leave at least an inch between them.
4. Bake for up to 20 to 25 minutes until they’re fully cooked through. Flip them over when they’re halfway through the process to make sure they’re brown on all sides.
5. Their internal temperature should be at least 160F. See above instructions for using a meat thermometer to test for doneness.
6. Take them out of the oven and serve them while they’re hot.
