Rosemary Garlic Pork Tenderloin

Prep Time: 10 Minutes   Cook Time: 1 Hour 25 Minutes   Serving: 2-6



We eat a lot of pork in my family. So, I always look for new ways and new flavors to prepare the pork dinner.

The first bite of the pork tenderloin is like a flavor explosion in my mouth. It just popped and WOW.....Then, you don't want to stop. You want more delightful explosions over and over again.

This meal is very low maintenance with simple flavor, but healthy. Enjoy!

The recipe looks long and complicated.  But it is NOT.  Basically, you just transfer the ingredients to the roasting pan and put it in the oven.  You need to turn in between to make sure it is cooked thoroughly.

For Pork Tenderloin
1.5-1.75 pound Pork Tenderloin
3 Cloves Small Garlic
1 hipping teaspoon Dried Rosemary
1/2 teaspoon Salt
1/4 teaspoon Black Pepper
3 tablespoons Extra Virgin Olive Oil
Non-stick cooking spray
4-7 toothpicks

For Roasted Potatoes Green Beans
1 pound Frozen Cut Green Beans (unthawed)
1 pound Russet potato (skin on; wash thoroughly; cut in bite size wedges, about 1" per side)
1 teaspoon Salt
1/4 teaspoon Black Pepper
1 pinch Crushed Red Pepper (optional)
1/4 cup Extra Virgin Olive Oil

For Gravy
2 tablespoons Flour
2 tablespoons Pork dripping
Butter (only use it if there is not enough dripping from the pork tenderloin)
2 cups Chicken Broth

Rosemary Garlic Pork Tenderloin

  1. In a big mixing bowl, combine all the seasonings (i.e. dried Rosemary, salt, black pepper and extra virgin olive oil) of the pork tenderloin
  2. Massage the meat in the marinade for 2-3 minutes
  3. Use a pairing knife to cut 3 holes on the meat with about the same distance apart from each other
    (Go easy on cutting the holes. The meat is so tender that the garlic could get exposed out of the meat and get burned during the cooking process. If you have to, use a toothpick to secure the garlic inside each hole so that it won't slice out)
  4. Put a clove of garlic in each hole
  5. Tug in both ends of the tenderloin to make them about the same thickness like the rest of the meat and secure them with 2 toothpicks each on either end
  6. Chill it overnight
  7. Adjust the racks, one is 2"and the other is 10" from the broiler
  8. Preheat oven at 400F
  9. Line 2 roasting pans with aluminum foil for easy clean up later
  10. Coat the pans with non-stick cooking spray
  11. Transfer pork tenderloin into one of the roasting pans (make sure the garlic gloves didn't pop out of the meat during the transfer)
  12. Cook for 30 minutes in the middle rack
  13. Turnover and cook another 30 minutes
  14. Turnover again and cook another 10 minutes
  15. Repeat the last step
    (If you cook the rosemary garlic pork tenderloin together with the roasted potatoes green beans, refer to the instructions below of how to coordinate in between)
    Total cook time of the meat is 120 minutes

Roasted Potatoes Green Beans

  1. While waiting for the meat cooking in the oven in the first 30 minutes, clean the potatoes thoroughly and cut into bite size wedges (about 1” per side)
  2. In a separate bowl, toss to coat the potatoes with the seasonings (i.e. crushed red pepper, salt, pepper and extra virgin olive oil)
  3. Add the green beans into the 2nd foil lined roasting pan; then top with the seasoned potatoes
  4. After the first 30 minutes of cook time of the tenderloin, put the pan of vegetables on the top rack
  5. Turn over the meat and cook together with the vegetables for another 30 minutes
  6. Turn over the meat again and toss the vegetables; cook for 10 minutes
  7. Turn over the meat last time and toss the vegetables; cook another 10 minutes
    Take the meat out and rest for 5 minutes
    (Every time when you turn the meat over, toss the vegetables so that they cook thoroughly)
  8. Turn off the oven and leave the pan of vegetables in the oven to keep it warm
    Total cook time of the side dish is 50 minutes

Tips

The cook time difference of the meat and the side dish is only 30 minutes.  So, wait for the first 30 minutes before putting the roasted potatoes green beans into the oven.

Gravy for the Rosemary Garlic Pork Tenderloin

  1. While the meat resting, transfer 2 tablespoon of pork tenderloin dripping into a medium sauce pan
    (If there is not enough dripping, replace the remaining required quantity with butter)
  2. Add flour into the pan and whisk to combine with the dripping and cook it at medium high heat
  3. Let the roux cook about a minute and whisk in 2 cups of chicken broth until gravy is thick
  4. Transfer to a gravy boats
  5. Take the toothpicks out of the meat and slice about 1" thick for each piece
  6. Serve along with the roasted potatoes green beans and gravy
    Total cook time of the gravy is about 5 minutes which you can do this while the meat is resting.

Double the Quantity of the Rosemary Garlic Pork Tenderloin Dinner

This recipe can easily double with the same cook time. Just to make sure to do the following:

  1. You will have 2 pork tenderloin. Make sure that their weights about the same for same cooking duration
  2. The meat should be about 2" apart from each other. Add 1/2 part more for all the seasonings (I don't recommend double the seasonings. It will be too much. Pork tenderloin is a kind of meat absorbing the flavors easily)
  3. Use a big baking sheet for the roasted potatoes green beans to allow them to be single layer. Double the seasonings for the vegetables
  4. Double everything to make extra gravy
    Follow the instructions of this recipe to prepare and enjoy

More Economical Options for the Rosemary Garlic Pork Tenderloin

Rosemary Garlic Pork LoinRosemary Garlic Pork Loin-an economic way to feed a bigger crowd

Yes, you can replace the tenderloin with just pork loin for an economical reason, especially if you need to feed a big crowd.

If that's the case, I assume that your meat will weigh at least 4 pounds or maybe more.  How long does it take to cook the pork loin?  The rule of thumb is an hour for a pound.

In other words, if you use a 4-pound pork loin, it will take about 4 hours to cook it.

That means it takes longer to cook. Also, make sure to cook the meat uncovered on the first and last hours of cooking. This will seal the juice inside the meat and form a
nice crust on the outside.  Cover the meat with aluminum foil in between.

If you decide to cook the roasted potatoes green beans as the side dish, make sure to put the vegetables in the oven until the last 50 minutes of the meat's cooking time.
