Ingredients to Make This Mustard Glazed Pork Loin Recipe

What Is Pork Loin?

Pork loin is a long, tender and relatively fat-free cut of pork that is removed from the ribs.

I like to buy it whole when it goes on sale. I cut a few roasts off the long loin, and cut the rest into boneless pork chops, freezing whatever I don’t plan on using right away.

How To Make Mustard Glazed Pork

This recipe really couldn’t be any easier! The toughest part is to make sure you don’t overcook it. Pork loin has very little fat and you want to make sure to cook it to 150-F MAXIMUM so it stays juicy.

  1. Make the glaze by combining the So Nourished brown sugar substitute with the mustards, cider vinegar, dried thyme, and garlic powder.
  2. Season the roast with salt and pepper.
  3. Spread the glaze all over the pork – top, bottom, and sides.
  4. Roast until perfect!

Special Equipment For This Keto Pork Loin Recipe

  • Digital Thermometer – the key to making GREAT roasts is to have a good digital thermometer. It’ll give you an accurate read on the temp of the meat

Chef Jenn’s Tips To Make Brown Sugar Mustard Glaze Pork Roast

  • Don’t overcook the pork! Pork is safe to eat at 145-F but I like it just a wee bit more than that so I pull my pork off the heat at 150-F. Use a good digital thermometer to get an accurate temperature for the very best keto pork recipes.
  • Let pork rest before slicing it. I pop it onto a cutting board and cover it loosely with a sheet of foil. Let it sit for about 10 minutes before slicing.
  • Fresh thyme can be used instead of dried. Just use twice as much.

What To Serve With This Keto Pork Loin Recipe

Keto pork recipes like this go amazingly well with so many different sides, but you don’t want anything too saucy or too flavorful so that the mustard glazed pork stays the star of the show. Some of my top picks would be Brussels Sprouts with Brown Butter and Almonds or Braised Kale with Garlic, and of course, some crunchy keto pickles on the side.

Is This Mustard Glazed Pork Loin Freezer Friendly?

You can freeze cooked pork, but I find that it tends to dry out. Especially this recipe, with no gravy.

To freeze it, chill it thoroughly then wrap it tightly in foil and then put it into a freezer zipper-top bag. Freeze for up to three months.

To eat it again, thaw it and then warm it gently in the oven at 325-F in a covered dish until it is heated through. Try not to overcook it.

Is pork keto?

Yes! Pork is definitely a great choice if you’re on a keto diet. It is high in protein and isn’t carby, so dig in!

How do you keep pork loin from drying out?

The easy answer is to not overcook it! Pork is safe to eat at 145-F. Use a good digital thermometer to help you cook it perfectly.

How many carbs are in pork loin?

There are ZERO carbs in pork loin.
