Roast Pork Loin with Onion Gravy

Prep Time: 5 minutes mins
Cook Time: 1 hour hr 25 minutes mins
Total Time: 1 hour hr 30 minutes mins
Pork loins can also vary in size and thickness. So cooking times will vary greatly, particularly if you bought the tenderloin, which cooks much faster. Cook the loin roast or pork tenderloin longer if it’s large or thick. If you are unsure on how long to cook your particular roast, cook the pork loin until it reaches an internal temperature of 140°F in its thickest part. As it rests it will still continue to cook and should reach an ideal internal temperature of 145°F. The higher the temperature, the drier the loin will be, so don’t go past 140°F while in the oven too much if possible.

Ingredients
For the pork loin:
- 2 pounds (907 g) pork loin roast
- 2 Tablespoons (30 ml) vegetable oil
- 4 cloves garlic , minced
- 1 teaspoon (5 ml) yellow mustard
- 2 Tablespoons (30 ml) Worcestershire sauce
- 6 Tablespoons (90 g) unsalted butter
- 1 Tablespoon (15 ml) dried herb mix ( basil, oregano and/or thyme)
- kosher salt or sea salt , to taste
- fresh cracked black pepper , to taste
For the onion gravy:
- 1 large onion , diced
- 1/4 cup (30 g) flour
- 2 cups (480 ml) broth (beef, chicken or vegetable)
- salt to taste
- black pepper to taste
Instructions
Preheat oven to 350°F. Rinse and pat dry pork loin, and then season with salt and pepper.
MAKE THE PORK LOIN: Heat a large oven-safe skillet on medium-high heat. Add oil and then sear the pork loin on all sides until a crust forms, about 1 minute per side. Remove pork loin from the pan and set it aside. Coat the pork loin with dried herbs by patting it onto the loin.
Turn off heat and remove pan from the heat. In same hot pan add butter, garlic, Worcestershire sauce, and mustard. Stir the sauce until the butter is completely melted. Place the pork loin back in the skillet and spoon some sauce over the pork loin.
Cover the pork loin with foil and roast for 30 minutes. Remove foil, spoon some more sauce over the loin and cook for about another 30 minutes or until the interior temperature reaches about 140°F.
Remove cooked pork loin skillet from oven. Remove the pork loin from the skillet and cover the pork with foil to let it rest for about 15 minutes (make the gravy while the pork is resting). (Don't clean the skillet, you'll need it for the next step in making the gravy.)
MAKE THE GRAVY: Heat the same skillet with the pork drippings on medium-high heat. Skim off any crust chunks in the drippings. Add onions and cook until golden and caramelized, about 5 minutes.
Whisk in the flour, whisking to remove lumps. Gradually whisk in the broth until incorporated and well combined. Season with salt and pepper, to taste (the saltiness and flavors will concentrate some when it reduces down).
Reduce heat to medium, stirring often, simmer until thickened, about 5 minutes depending on your preferred thickness. Check for seasoning and salt again if needed. Slice pork loin and serve hot with the onion gravy.
Notes
Recipe Note: If you don’t have an oven-safe skillet, the pork loin can be seared on the stovetop on whatever skillet you do have, and then finished in an oven-safe baking dish. It just leaves you with another dish to wash.

We just got done with Sunday dinner and this recipe rocks the house! Hubby is a heart patient so I cut back the butter to 2 Tbsp and subbed olive oil, but the gravy turned out awesome. Thank you for the recipe love!-

Made this the other night and it was great, although I had to make a slight change — we were out of Worcestershire so I substituted tamari soy sauce, it it worked well (Worcestershire can be rather dominant in some dishes, soy not so much). At the end I decided the sauce was a bit thick and added about ¼ cup of Sherry, which kicked up the flavor a notch. The next time I make this I may add mushrooms and maybe some carrots. Very veritas dish!-

Do you recover the roast with the foil the 2nd 30 min or leave off? It’s in the oven now lol-
Best Recipe Box — Reply
Hi! We do not re-cover with foil during the 2nd-30 minutes. But it does get covered in foil during the resting period in step 6.

The pork roast turned out perfectly. I had never done pork loin roast before and was nervous but it was delicious, from the mustard sauce to the onion gravy. I added Brussels sprouts, a potato, carrots and celery in the second half hour to accompany it. Thanks for sharing!-

4.9. The pork loin was delicious. The herb seasoning and searing the meat made it pop. Thank you so much for the juicy recipe! -

Made this tonight – both 6 year olds at the table LOVED it as much as the adults! Probably adding to my Easter meal lineup…it was that great. I cut a four pound loin into two 2 pound pieces and doubled the recipe – it turned out just fine and I really didn’t even need to adjust cooking time. Also, the sauce was so great I forgot to make the onion gravy! We will have the gravy at Easter for sure!

I made this for my boyfriends family. Served it with egg noodles for the gravy and they always ask me to make “that pork with the gravy” when they get a pork loin. I love this recipe and I love to add little things to it like potatoes in the pan or dijon mustard instead of yellow. Bottom line is this recipe is soooo delicious by itself !-

I’m excited to try this esp after reading the reviews. I do however have a 4 1/2 pound pork loin. How much longer do I cook it for?

Best Recipe Box — Reply
Hi Pia, you might want to add another 10-15 minutes in the oven. But definitely use a thermometer to ensure that the pork is cooked to your liking.

Delicious and relatively simple. Whisked flour with water into gravy to avoid lumps. Cooked onions about l0-15 minutes to caramelize. Gobbled up. Will make again. Thanks! -

Wow. So delish. Made this for my son and mom last night. Easy and love that it is in just one pot! I used LeCreuset Dutch oven. I then got a call that my son wasn’t coming home for dinner after all! :::Sigh::: So I set the pork roast on the gravy covered it and put it in the refrigerator overnight. We finally ate it tonight and the pork was tender and the gravy fantastic. This will be on our rotation. It tasted restaurant quality! Thank you.-
