Line a baking sheet with parchment paper, and fit it with an oven-safe cooking rack (optional - helps with even browning).
Space the breakfast sausages 1 inch apart on the baking sheet or cooking rack.
Bake in the preheated oven for 14-16 minutes, turning the sausages halfway through the baking time.
The sausages are done once they reach an internal temperature of 165ºF (74ºC) (they are safe at 145ºF (63ºC), but taste better when they are cooked a little longer).
If you want your sausages to be browned or extra crispy, stick them back into the oven and set the oven to broil. Cook for 1-3 minutes, or until cooked to your liking. But watch them carefully! (Note: Only do this if your baking sheet is broiler-safe)
Allow to cool for several minutes, then serve immediately or cool and store for later.
Notes
*Breakfast sausage patties: These may need a little less time, since they are typically thinner. Cook them for 12-14 minutes, checking the internal temperature to ensure they are safely cooked through.From frozen: You will need to add another 10-15 minutes, and be sure to check the internal temperature to ensure they are safely cooked through.Storage: Allow the sausages to cool completely, then transfer them to an airtight container or storage bag. Keep in the refrigerator for up to 3 days, and reheat before serving.Freezing: Allow the cooked sausages to cool completely, then transfer them to a parchment-lined baking sheet. Place the baking sheet in the freezer until all of the sausages are frozen solid. Transfer them to a freezer bag or container, label, and store in the freezer for later use. Thaw before serving, or reheat from frozen. Freezes well for up to 3 months. Reheating: You can reheat them in the microwave in 30-second intervals until steaming hot. Alternatively, you could add them to an air fryer set at 350ºF for 2-4 minutes, or until heated through.
