Growing up, Sunday dinners were a big deal. My Mum would cook for whoever lived at our house, and whoever happened to be around that day.

If you were a friend of the family, you made sure you “happened to be around” on a Sunday. A spot at our table guaranteed a big roast dinner, mashed potatoes, vegetables and of course, a full-flavored gravy. YESSSSSS.

This post is really about how to cook a pork loin. You don’t have to get fancy and use fresh herbs, or garlic. Simple salt and pepper will get the job done just fine.

  • This is super simple. Just mix up some seasonings, and throw the pork in the oven and you are good to to.

What to serve with Pork

I am pretty traditional, and love to serve potatoes alongside Roasted Pork. Try Honey Mustard Roasted Baby Potatoes, Mashed Potatoes, Twice Baked Potatoes or Scalloped Potatoes. More Side Dish Recipes.

Frequently Asked Questions

How much pork do I need per person?

About 4oz per person. At 26 grams of protein per 4oz serving, it packs a filling punch! Flavorful and satisfying!

How long does a pork loin take to cook?

A good rule of thumb is about 20 minutes per pound. So, 1 hour and 20 minutes for a 4lb roast.

What temperature should pork be cooked to?

Pork chops should be cooked to 145 degrees F when tested with a digital thermometer in the thickest part.

Why does pork need to rest?

Simply put, resting after roasting results in juicier meat. Resting allows the juices to settle throughout. If you slice right out of the oven, all the juices run out – and you get dry pork.

The good news is you can make gravy while the pork rests.

What to do with leftover pork loin?

Use leftover pork in enchiladas. Or, shred it and add BBQ sauce and make sandwiches.

Another fun idea is to make carnitas! Shred the pork and mix with cilantro, lime, black beans, and taco seasoning, and wrap in a corn tortilla)

  1. Excellent! I cut this recipe in half for 6. Made as outlined without the gravy and 4 adults and 2 small children ate the entire meal! Next time I will roast in a 9/9 pan to make the drippings easier to harvest for the gravy. I would also increase the herbs to get more crust on the loin. Resting time is critical for a perfectly cooked roast. Easy enough for a week night dinner and I know the pork would make perfect sandwiches for lunch to clean up any leftovers
