What You Need to Make Keto Roasted Pork Tenderloin

You can use your favorite blend of herbs for this dish, but key ingredients NOT to miss are:

Fresh garlic – the finer it is chopped the better. Don’t use the stuff in a jar. It just doesn’t have the same flavor intensity.

Cooking oil – I like olive oil but use your favorite. Oil will help the herbs and garlic get rubbed around.

Dried herbs – Rosemary, thyme, oregano, basil, and tarragon are all tasty choices. Mix and match to find your favorites.

Salt & Pepper – freshly ground pepper, please.

How to Prepare Keto Roasted Pork Tenderloin

Pork tenderloin is super-simple to cook, but it takes a few minutes of prep to get it ready for the oven.

You see, there’s this pesky stuff on the tenderloin called silver skin that needs to be removed before you roast the pork. It is tough, chewy, and not so nice.

The good news is, it only takes a minute to remove it. This Bacon-Wrapped Pork Tenderloin recipe has some pictures showing you how to remove the silver skin.

Once the skin is removed, simply mix your herbs, salt and pepper, and garlic with the olive oil.

Now get that herbaceous mixture rubbed all over the pork tenderloin. Get your hands in there, don’t be afraid!

Now all it needs is a quick trip in the oven at 375-F on a sheet pan with raised sides, to catch all the juices.

Line the pan with some parchment paper (every home cook should have parchment paper – it’s a lifesaver!) for easy-peasy cleanup.

A room temp pork tenderloin could take as little as 10-12 minutes in the oven, but it depends on the size and the starting temperature of the pork.

Allow up to about 20 minutes cooking time, but check the temperature of it around 12-13 minutes.

Perfect pork tenderloin comes out of the oven with an internal temperature of 145-150-F, and let it rest for a few minutes before serving. Use a good digital thermometer to get an accurate (and quick) result.

Chef’s Tips:

  • Save some time by using a spice blend like Greek, Italian, or Mexican. Just make sure that the spice blend is sugar- and starch-free.
  • You can prep this pork tenderloin the night before. Trim it and rub it with the herbs/oil/salt & pepper and it’ll marinate overnight. Double yummy!
  • Don’t overcook your pork tenderloin! There’s pretty much ZERO fat to this cut, and it’ll dry out super-fast if you overcook it. Pull it out of the oven at 145-F and let it sit a few minutes before cooking. A pink blush in the middle is just fine.

What to Serve With Garlic & Herb Keto Roasted Pork Tenderloin

Unbelievably tender, juicy, and full of flavor, you can’t go wrong with this Garlic & Herb Roasted Pork Tenderloin! Serve it with your favorite veggies, or check out a popular pick like Green Beans with Bacon or Cauliflower No Mac ‘n Cheese.

Don’t forget the Horsey Sauce! This is a must with this pork dish – the Horsey Sauce is creamy and has a bit of a spicy tanginess from the horseradish.
