Pork tenderloin is easily the best cut of pork for roasting, but it can be really tricky to get it just right. This recipe for Rosemary Garlic Parmesan Pork Tenderloin uses a few simple additions to turn a regular tenderloin into something incredibly delicious.

Roasted Pork Tenderloin

The trick with cooking pork tenderloin is in making it come out at the right temperature and how to stop it from drying out.

With the addition of a few herbs and some olive oil, you can get the crust to taste incredible without sacrificing tender meat when you cut it open.

Rosemary Garlic Parmesan Pork Tenderloin Ingredients

Check the recipe card at the bottom of the page for the full ingredient list and amounts.

  • Pork tenderloin
  • Olive oil
  • Parmesan cheese
  • Garlic
  • Dried rosemary

How to Make Pork Tenderloin

  • Combine all of the ingredients into a paste and then rub it all over the pork
  • Bake the coated tenderloin at 350 Fahrenheit for 35-45 minutes, or until the pork registers 145 Fahrenheit internal temperature
  • Rest for 10 minutes before slicing and serving

How to Cook to the Exact Right Temperature

Cooking pork is always tricky, no matter how experienced you are. Do you make sure to cook it all the way to well done but suffer the terrible texture, or do you cook it pink and risk getting sick?

Well, despite what you’ve probably been told your whole life, you can actually cook and eat pork to a pink medium rare just as you would with beef.

As long as you cook it to an internal temperature of 145 Fahrenheit, it is perfectly safe.

In fact, you can actually pull your pork tenderloin when it hits 140 Fahrenheit; it will coast the last 5 degrees while it rests and hitting 145 Fahrenheit by the time you want to eat it.

Having an instant-read thermometer is perfect for this, as it lets you know exactly how your meat is doing without having to cut into it or, even worse, take a guess.

How to Slice Your Tenderloin for Serving

While it would be tempting to just eat your tenderloin in one big piece, you obviously need to slice it for serving. You can cut it into small medallions for serving, cutting from the smaller side first.

To help to make it extra pretty on the plate, try and slice it on a bias. This means not just cutting it in slices straight down with your knife but actually cutting it at an angle away from you as you slice it. It is sort of like cutting down at a 45-degree angle away from you.

This results in tiny slivers of meat with the maximum surface area possible, resulting in some really tasty meat.

  1. Debbie Spencer was Worley says

    I like pork tenderloin but I’m not a huge fan. This recipe changed my mind it was the best pork tenderloin I have ever eaten. Don’t over cook it leave it may be just a tad pink and the rosemary was fabulous on it.5 stars

  2. goody says

    Could you do some vegan main dishes as well? I don’t eat meat, but from time to time I have seen you do recipes without meat. Thanks for posting 🙂

  3. Joan Maria says

    Can’t wait to make this sounds delicious 😋

  4. Theresa H. says

    Hey there! This recipe looks amazing! But, I’m not a fan of rosemary. Any ideas on what I can substitute rosemary with?

  5. we loved it says

    Ok, with the fresh rosemary this was pretty amazing and super easy. The prep took a little more than 3 minutes for me, 15 actually. But that included going out to the garden for fresh herbs and just generally being slow at chopping.5 stars

  6. Kerry says

    Looks awesome, I’m going to try this tonight. Simple yet delicious recipes are a life saver. Thank you!!!

    Even though you had Pork… I still kept seeing prok through the whole thing. lol.5 stars
