Juicy on the inside and crisp on the outside, this Garlic Brown Sugar Pork Tenderloin is perfect for any family occasion. Better yet, it’s made in one dish and requires only 10 minutes prep. It couldn’t be easier!

Like any good Southern lady, my Mamma raised me right! While I wouldn’t call us superstitious, she taught me that there are definitely certain traditions to preserve.

The Spencer Family recipe for Rich Chocolate Frosting is a must on any yellow birthday cake; ambrosia is a staple on every Thanksgiving table; and pork tenderloin is a given on New Year’s Day. We don’t fool with what works or question our good fortune — and wouldn’t you want to start the New Year off right by enjoying a dish that signifies wealth and prosperity too?

The truth is, I vividly remember childhood New Year’s Day dinners as fancy occasions with extended family. Mom would prepare a pork dish, and always, always, always serve it alongside Hoppin’ John, greens, and sauerkraut.

While my Mom definitely raised me well, I can freely admit that my take on New Year’s is not quite as refined as hers!

Make Pork Tenderloin The Easy Way

My idea of a lucky pork tenderloin is one that tastes fancy enough to serve our guests, but that only requires about 10 minutes of my time! Our meals are casual affairs with 4 hungry boys around the table. I don’t fuss over the details, I’m not afraid of shortcuts, and I want effortless food that also happens to taste amazing.

Whether you welcome a New Year with one of my family’s favorite traditions, or whether you’re just serving a quick and easy weeknight dinner, this pork tenderloin is bound to make you feel lucky.

I will pair my pork tenderloin with Hoppin’ John and greens on New Year’s Day (just like Mom taught me); but it’s equally delicious alongside a big hunk of cornbread with melted butter and honey on top on any given Wednesday night!

No matter when or how you choose to enjoy this dish, it’s a quick-prep meal that will soon become a favorite in your household as well!

    I don’t think we ever had a New Year’s Day dinner growing up. It was usually an extension of Christmas with another side of the family. I think this a tradition that needs to happen though. Merry Christmas friend!

    1. Blair says:

      Merry Christmas, Megan! I hope that you have a wonderful holiday and maybe even start a new New Year’s tradition! 🙂

  2. Kristy from Southern In Law says:

    I hope you and your sweet family have a wonderful Christmas! xo

    1. Blair says:

      Thanks, Kristy! It’s delicious. Enjoy that pork tenderloin and have a wonderful holiday with your family!

    Trying to meal plan today and thought of your site! Thanks for the great ideas…I so need help. I get in such a food rut this time of year! Pork Tenderloin here I come!

    1. Blair says:

      Grayson! I love that! So glad that you thought to hop on over here…enjoy that pork! 🙂 xoxo

  4. Christina says:

    Does the brown sugar make this taste sweet? Can that be omitted?

    1. Blair says:

      Hi, Christina! The brown sugar definitely adds some sweetness, but it’s not overpowering at all. I wouldn’t call the pork “sweet.” That said, if you prefer to leave it out, you certainly can. The finish on the pork will be a bit different, though, because the sugar helps the top caramelize and get crispy when you put it under the high heat of the broiler. Just something to keep in mind. 🙂

      1. Kevin Freestone says:

        Try mixing honey with the mustard and this gives the same affect without using sugar. This approach shoukd tenderise the meat more.

        1. Blair says:

          Great tip! Thanks! 🙂

  5. Melissa says:

    Looks delicious can I use a 2lb pork tenderloin instead? Would you cook for about 45 minutes then broil for 5 ?

    1. Blair says:

      Hi, Melissa!

      That’s a pretty big tenderloin! They’re often sold in packages of two. Have you opened the package to make sure that you don’t have two separate tenderloins packed in there?

      If you’re really cooking a 2-lb. tenderloin, a good rule of thumb is to cook the tenderloin at 400 degrees for 10 minutes. Then reduce the heat to 350 degrees and continue roasting for about 20 minutes per pound. The best way to really tell if your meat is properly done, though, is to use a meat thermometer and remove it from the oven when it reaches between 140-150 degrees. You can pop it under the broiler during the final few minutes if you’d like that nice char on the outside, but it’s not necessary. Let it rest for about 10 minutes (it will continue cooking as it rests), and then slice and serve.

      Hope that helps!

    I have made this recipe So Many Times since finding it that I now basically eyeball the ingredients and it still turns out amazing every time! I double the sauce ingredients, toss baby carrots around the tenderloins, add some sort of potato on the side, and dinner is done. Husband and kid approved! Thank you for this delicious, easy dinner! Makes fantastic leftover pork for bbq sandwiches, too!

    1. Blair Lonergan says:

      That’s so good to hear, Lynn! Thanks for your note. 🙂

    Make this all the time, it’s foolproof! We double the sauce and add carrots to the roasting pan as well.
