Ways to serve this

No pork sirloin roast is a tender lean cut that cooks more quickly. Pork roasts are great for low and slow cooking because they come from the shoulder and have more fat on them. The pork sirloin roast is treated more like the pork loin or pork tenderloin. It cooks faster that a shoulder roast and you need to be careful not to overcook it.

Yes if it’s cooked to the proper temperature it’s a tender lean cut that’s very tasty. Like with a pork tenderloin, you should use an instant-read thermometer to make sure it doesn’t get too done.

I don’t recommend it because the cooking times are different. Try my Honey Mustard Pork Loin or Best Baked Pork Tenderloin instead. They are made just for those cuts of meat.

  • To store, put any extra pork roast in a container that won’t let air in and put it in the fridge for up to 4 days.
  • Make ahead: This tastes best when made right away, but you could make it ahead of time so you have pork for salads and other things.
  • Reheating: Put any leftovers in a small skillet with some of the pan juices or gravy. Heat over medium heat with the lid partially on top until hot all the way through, adding water as needed.
  • To freeze—this pork roast freezes well. Put any extra slices in a container that won’t let air in and freeze for up to three months. After a month, I think the leftovers are best eaten. Also, I love cutting up leftover pork before I freeze it so it’s easy to add to other foods.

FAQ

What is the difference between pork roast and pork sirloin roast?

Steaks cut from a rib roast are pork loin chops or pork rib chops. Pork Top Loin Roasts are created by the butcher by tying two top loins together with the fat sides out.

What temperature should pork sirloin be cooked at?

The safe internal pork cooking temperature for fresh cuts is 145° F. To check doneness properly, use a digital cooking thermometer. Fresh cut muscle meats such as pork chops, pork roasts, pork loin, and tenderloin should measure 145° F, ensuring the maximum amount of flavor.

Can you use a pork sirloin roast for pulled pork?
