I’m in love with all the meats and seafood smothered in garlic butter. And really, can you blame me? I mean, what’s not to love? Butter in general makes everything better, and garlic AND butter? That’s a no-brainer.

Not only is this roasted pork tenderloin smothered in an herby garlic butter before it’s baked, but also after it comes out of the oven for a 1-2 punch of flavorful, finger-licking goodness!

Why This Recipe Works

Easy to put together and even easier to eat — this pork tenderloin is a tasty treat! 

Buttery — The creamy smoothness of butter makes everything better. Plus, we all have a half a cup of butter in our fridge/freezers right? It’s not just for toast! 

Easy — This pork tenderloin roasts in the oven for 35 minutes max. That means you have time to make a salad (may I suggest my Easy Greek Tossed Green Salad?) and a side (for an idea, try my Best Italian Orzo Salad) to go with the pork. 

Tender — Using a fork to pierce the meat before smothering the tenderloin in herby butter means when it melts, that buttery goodness will cook right along inside the pork. Letting it rest for another 10 minutes after it comes out of the oven means even more time for the juices to lock in and come out amazingly tender

Budget-friendly — A large pork loin can easily feed my family of four with lots to spare for leftovers. Cook once, eat two or three times! 

Pantry staples — Other than the pork and butter, all you need is salt, pepper, garlic, and an Italian seasoning blend!

Here’s How You Make It

  1. Preheat the oven to 400 degrees.
  2. Take a small bowl out and make the garlic butter by combining ½ cup of butter with minced garlic, garlic powder, and herbs. Set this mixture aside.
  3. Take the pork out of the package and pat it dry with paper towels. 
  4. Using a fork, poke holes all over the pork tenderloin. 
  5. Season the pork all over with salt and pepper. 
  6. Add the tenderloin to a greased, rimmed baking sheet or casserole dish. 
  7. Rub half of the garlic butter mixture all over the top of the pork. Keep the rest in the dish off to the side for later use.
  8. Put the pork in the oven for about 25-35 minutes. The outside should be brown and the inside should no longer be pink. Use a meat thermometer if you like to take the internal temperature of the tenderloin, it should read 145 degrees for it to be done.
  9. Finally, take the pork out of the oven and let it rest for 5 minutes. Add the rest of the garlic butter mixture to the top and sides of the tenderloin. Rest again for 5 more minutes
  10. Slice and enjoy!

Frequently Asked Questions

How Many Minutes Per Pound do you Cook a Pork Tenderloin?

A general rule of thumb is to cook pork tenderloin for about 20 minutes per pound at 400 degrees or until the internal temperature reaches 145 degrees. 

Should you Cover Pork Tenderloin in the Oven?

I don’t cover the pork in the oven. I like for it to get a nice, crispy, browned outside. By using foil to cover the tenderloin, you’ll end up more steaming it all around and it won’t develop that crust. Essentially it’s up to you though how you’d like it to cook and your own personal preference.

Expert Tips

  • For the herb mixture, my choice is always Herbs de Provence. But, you can substitute any Italian seasoning blend or make your own with 1 tablespoon of chopped fresh parsley plus 2 teaspoons of any other fresh, chopped herb (like thyme or oregano — or both). 
  • After resting, the best way to cut into a pork tenderloin is to cut across the grain, rather than parallel to it. 
  • Salted or unsalted butter. But if you use unsalted, add ¼ teaspoon of salt to the butter mixture alongside the garlic and herbs.
  • Want your roasted pork tenderloin more on the spicy side? Add a dash of red pepper flakes (or more if you love the heat!) to the butter.

    Delicious! Adding to my faves for the fam. I just have one question – my pork doesn’t seem to brown up and I don’t want to overcook it. Tips?

    1. Tiffany says:

      There could be a couple of things that happened to prevent the pork from browning. The pork could’ve still been a bit wet and wasn’t completely dry, the oven wasn’t hot enough or you used a pan that was too small so it was “overcrowded” hope this helps and it works better next time! 🙂
