Cooking to the Correct Temperature

According to the USDA, it’s recommended to cook pork to at least 145 degrees Farigheinght. When you cut into it, it may be slightly pink and that’s 100% okay. In fact, that’s great, as that means it won’t be too dry.

Allow the meat to rest for 3 to 4 minutes before slicing and eating it.


The recipe uses ground-up rosemary, thyme, and mustard. To grind up the herbs, I used my magic bullet blender with the shallow blade. If you don’t have this option, you can also use a coffee grinder.

If all else fails, don’t worry about using the ground herbs. I just like to grind it so it’s easier to spread with the dijon mustard over the loin. Breaking up the spices also allows the flavor to really come out as well.

Keep your keto pork loin in airtight glass dish in the fridge. For best results, allow the pork roast to cool before you seal the lid. We want the meat to cool faster rather than slower. The meat will last up to a week in the fridge.

Left Over Ideas

If you get tired of just eating the roast, you can easily add it to different meals, to mix things up for yourself.

  • A salad with pork as the main protein.
  • Make a lettuce wrap sandwich with some G Hugh’s BBQ sauce.
  • Use the base of this pesto egg cup recipe and add in some chopped pork.
  • Make nachos with the left over meat.

Reheating Left Overs

Reheating a pork roast can be difficult especially with it being a lean cut of meat. The trick is to cook it over the stovetop with a lid over your pan. This helps keep the moisture in.

First slice up the portion you want to reheat, then add some avocado oil or coconut oil to the pan. Turn the burner on medium-low and allow the oil to heat up. Place the slice of pork in the pan and cover for about a minute. After the minute is done, flip the meat. Repeat the flipping until it’s come to the temperature you want.

If you want to heat up the whole pork loin, keep it on its side for 2-3 minutes before you flip it. Since the roast will be thicker, than the slices, reheating it this way will take longer than the slices.
