How To Cook Pork Loin Roast

When feeding a larger crowd in a hurry, here’s what you need to know for moist and tender pork slices every time.

Pork Selection

The loin is a moderately lean cut, that is mildly flavored meat and can yield tender pieces when cooked properly. Pork loins range in various sizes, from around 2 to 5 pounds. I chose a 2 ½ pound filet for this recipe which can serve about four people. Some markets carry fresh pork already with a flavorful dry rub seasoning, so you do not need to add any extra ingredients when preparing. It’s so easy to cook, especially when you don’t have time to spare.

Cooking Techniques

To bring out additional natural flavors of the pork loin, I sear the meat in a very hot pan for a few minutes on each side before roasting. This allows Maillard browning reactions to occur, creating a beautiful brown surface and more flavor compounds.

If the large-sized pork loin is cooked only on the stovetop, the meat would be too dry. To prevent overcooking, even and gentle heat is applied in the oven for a slow loin roasting at 400-degrees to maintain the moisture inside the pork.

Timing and Doneness

The size of the pork loin will determine cook times. For a 2 ½ pound roast, 30 to 35 minutes is needed for medium doneness. To check for the doneness of the pork, it helps to use an instant-read thermometer. For a medium cook target 140°F to 145°F (60°C to 63°C) endpoint to allow for carryover cooking. The final internal temperature will be around 145°F to 150°F (63°C to 66°C) after resting for 10 minutes.

Sheet pan dinner

I’m a big fan of roasting pork on one big tray with all of the vegetables. This gives the garlic and shallot aromatics time to infuse into the meat and other vegetables. The zucchini, yellow squash, corn, tomatoes, and asparagus also absorbs the savory juices from the pork loin roast instantly adding more flavor, win-win! The vegetables don’t need as much time to cook, so it’s added to the tray 10 minutes later to give the pork loin a head start in cooking.

You can use these cooking techniques and this recipe with any flavor of pork. There is a variety of fresh pork like tenderloins and larger roast options at the market, so you never get flavor fatigue. If you are feeling bold, try grilling, sauteing or even stir-frying the pork to add different dimensions of flavor and texture to each meal.

This rustic herb pork loin roast with hearty vegetables will satisfy your hunger with wholesome and fresh ingredients! We had some leftovers after the meal, so I pureed the extra vegetables with some hot stock to create a soup, and stirred in some chop pork roast and packed it up for lunch the next day.

Why is it important to rest the pork loin before slicing?

After the roasted loin is removed from the oven carryover cooking occurs, allowing the heat to continue to travel and cook the center of the pork. Resting gives the heat transfer a few additional minutes to get to the desired doneness level. Resting the meat before slicing also helps retain the moisture inside. The water that has been squeezed out of the myofibril muscle fibers in the pork during cooking gets a chance to reabsorb back into the spaces where dissolved proteins now reside. The result, moist and tender roasted pork!

    Thank u. I made this it was delicious. I had 2 put some veggies in a separate dish cause they were overflowing & the meat took a long time. But came out good. Made rice as a side. We ate all of it.

    I’m all about a single sheet pan dinner, too! I love all of the summer veggies you included in this one. I definitely need to add this to our menu soon. Thanks for sharing!
