Rosemary Garlic Oven Roasted Pork Tenderloin

I don’t need anyone to give me incentives to love pork more than I do… I mean… not only is pork delicious, but I have found it to be one of the EASIEST dishes to prepare.

Read: easy and delicious dinners make mama happy and when mama’s happy…

You catch my drift.

Plus, the weather is turning down the volume on the heat and during the cold months of the year everyone in the family loves the smell of a good hot meal in the oven. Or crock pot, but I’ll talk more about that crock pot later this month…

One of my favorite recipes (and by favorite I mean FAVORITE) I make that celebrates pork and makes mouths water is my Rosemary Garlic Roasted Pork Tenderloin. Pretty sure your mouth just watered. Serve it up with a baked sweet potato and you are almost willing to wave off Spring and Summer altogether.

I like to get my pork at Costco. Theirs is an offering of a variety of pork cuts at a great value. PLUS… I can also shop for all the equipment I need to make my holiday favorites!

Shopping at for pork at Costco via @jennyonthespotBut enough about my shopping habits – how about this amazing recipe?

You will need olive oil, rosemary, garlic, salt, pepper, and pork tenderloin.

I also like getting my pork at Costco because I get a lot. These pork tenderloins come in a two pack, and each pack has TWO tenderloins. I cook one package of two tenderloins right away, and freeze the other.

So. THE RECIPE… Take your rosemary and separate the leaves from the stems.

rosemaryChop up the rosemary and breathe deep… enjoy the delicious smell. Your nose will thank you.


Mince the garlic. I love my garlic press. I never use minced garlic from a jar, but you are more than welcome to do what works for you!

Add the chopped up rosemary, minced garlic, salt, and pepper to the olive oil.

And stir.

Spray a 9 x 13 glass dish with cooking spray and lay the tenderloins on the prepared dish. Then get a basting brush and brush that rosemary garlic goodness all over your pork tenderloins… not forgetting to take deep breaths so you don’t miss any chance to breathe in the fragrant rosemary!

It’s not too much, I promise…

Use it ALL.

Place the dish into your preheated to 400 degree oven. In about 30ish minutes (note: mine has never taken under 30 minutes) your masterpiece should reach it’s optimal temp — an internal temperature between 145°F (medium rare) and 160°F (medium), followed by a three-minute rest, using a digital thermometer to ensure accuracy.

Speaking of nailing it…

Surround your rosemary garlic oven roasted pork tenderloin with the most beautiful produce… I think sweet potatoes and broccoli are VERY beautiful. The sweetness of the sweet potato compliments the savory juices of the pork tenderloin LIKE A BOSS. The broccoli is green and that’s my favorite color and it is the MOST favorite veggie in my family so yeah… broccoli is definitely beautiful to me!

    2 tablespoons coarse salt
    1/2 teaspoon freshly ground white pepper
    1/2 teaspoon ground coriander
    1/2 teaspoon ground mustard
    1/4 teaspoon plus a pinch of ground allspice
    1 boneless pork loin, about 2 pounds, tied
    2 tablespoons vegetable oil
    2 cups dry white wine, such as Sauvignon Blanc
    2 bay leaves
    15 small orange, red, and yellow carrots, peeled, trimmed if desired
    15 red pearl onions
    10 small parsnips, trimmed and peeled
    3 garlic cloves, crushed with the flat side of a large knife
    6 red d’Anjou pears

    STEP 1
    Combine salt and spices. Coat pork with the spice mixture, and let stand at room temperature 30 minutes.
    STEP 2
    Heat a large Dutch oven over medium-high heat. Add oil. Add pork to pot. Sear pork until golden, turning with tongs, about 2 minutes per side. Stir in wine and bay leaves, scraping bottom of pot to loosen browned bits. Bring to a boil. Reduce heat to medium-low. Partially cover, and simmer, basting meat with cooking liquid several times, 25 minutes. Remove pork from pot, and set aside.
    STEP 3
    Stir in carrots, onions, parsnips, and garlic. Simmer, uncovered, 10 minutes. Make a well in center; return pork to pot. Quarter and core pears (peel and leave some whole if desired). Add pears, and simmer until pears are tender and a meat thermometer inserted into center of pork registers 145 degrees for medium, about 15 minutes. Let rest in pot 5 to 10 minutes before slicing. Transfer the vegetables and pears to a platter with the sliced pork. Pour sauce through a fine sieve into a bowl; pour over pork.

  23. Cristi Comes says:

    I am the worst chef of pork ever so no recipe here. I’m a pretty basic cook. This dish looks wonderful.

  24. Ingrid says:

    Looks delish!

  25. Brittany Koelmel says:

    I LOVE pulled pork sandwiches!

  26. livivua says:

    i love pulled pork and pork and zucchini vegetable kabobs

  27. tammigirl says:

    My favorite is pulled pork – tied with pork ribs.

    I have a really great rub for them – once they are cooked I slather on the barbecue sauce and we DIG IN!

    Low and slow, is really the most important part. The rub and sauce is up to the individual tastes of whoever is eating it.

  28. tammigirl says:

    I had to come up with my own pin because yours in the rafflecopter doesn’t work.

  29. Samantha says:

    I was wondering why Costco had the pork loins on sale the other day, I think they were $4 off each package. I’ll have to head back and grab a few. We actually just had your recipe this past Monday for dinner, it was delicious. Another favorite of ours is Stovetop Pork Carnitas from Clothes Make the Girl, I use Pork Loin instead of shoulder and they taste wonderful…..lots of yummy cumin in the sauce after.

  30. Susan Christy says:

    Pork carnitas in the crockpot for tacos, burritos or just with tortillas and some rice and beans.

  31. Eileen says:

    I like to do a pan-seared pork roulade stuffed with spinach and onion and finished with some burst cherry tomatoes. So good! Thanks for the giveaway opportunity!

  32. Sherrie C. says:

    My favorite pork recipe is my mother’s roasted cajun pork seasoned with Tony Chachere’s Famous Creole Cuisine, minced garlic, and chopped onion and served with baked sweet potatoes and sweet peas. Thanks 🙂

    I love my father in law’s barbecued pork ribs.

  39. […] you happen to catch my last Porktober post.. the one with the super easy, super delicious Rosemary and Garlic Roasted Pork Tenderloin recipe? […]

  40. Lisa Aliperti says:

    We make pork tacos at our house. It’s slightly different every time but includes garlic, onions, peppers, cumin, cilantro, sea salt and lime.

  41. Marie says:

    For Thanksgiving our family would sometimes pay homage to our Cuban ancestry and roast a tender and flavorful pork shoulder. Interestingly enough, I seem to recall that the best cuts of pork shoulder with ample amounts of meat could always be found at Costco and for the best price! The pork would marinade overnight in olive oil, garlic, onions, fresh lime juice, cumin, red chiles and salt and pepper. My father would make multiple incisions throughout the shoulder and stuff the onions and garlic pieces inside. The house smelled amazing as it cooked at a low temperature for several hours while black beans and rice simmered in a pot on the stove. It made for a tasty and spicy diversion from traditional turkey and delicious cuban sandwiches for lunch with the leftover meat.

  42. Meaghan says:

    We don’t eat a lot of pork, but this recipe looks good!

  43. Jennifer Jordan says:

    Yum! Definitely going to try this. I just made your Pork Sirloin Tip Roast with apples and bacon in the crockpot last night. It was amazing. Thank you for the new, fresh food ideas.

  47. Erica Cannon says:

    The instructions on the blog are different than the print out card. The blog says 400 degrees for at least 30 mins and the print out card says 425 degrees for 45 minutes…. I am worried I am gonna burn this is I cook at a higher temp for longer… so which one should I use? I am horrible in the kitchen, my specialty is burning water, so I would really like to try to get this right!!! Please help!

    • Jenny says:

      OH goodness! I don’t know how those numbers got… all janky! Thank you for calling that to my attention. It is 400 for 30 minutes! It would absolutely get overcooked at the other. Thank you so much for checking. I am going to fix that right away!!!
