Preheat the oven to 400 degrees. Line a rimmed sheet pan with foil or parchment paper.
Place the sausage links on the sheet pan, leaving a little room between them to brown up nicely.
Bake for about 20 to 25 minutes, flipping them once halfway through cooking. Use an instant-read thermometer inserted into the very middle of the sausages to check that the internal temp is at least 160 degrees. Serve hot.
Notes
Storage and Leftovers
Leftover baked sausage will keep in the refrigerator for up to 5 days in an airtight container. Reheat leftovers, wrapped in foil, in a preheated 350-degree oven for 10 to 15 minutes. The foil will prevent them from drying out. You can also reheat them in a microwave.
