Sear-roasted pork tenderloin with a sweet mustard glaze—your ticket to an effortlessly chic dinner, any night of the week or for special occasions.

Adapted from cookbook author and food columnist Marian Burros’ 5-star mustard-glazed pork tenderloin, a gem first featured in The New York Times in 1989, this marinated and sear-roasted pork tenderloin makes a fancy weeknight dinner or special occasion roast. The marinade—a simple blend of mustard, brown sugar, rosemary, and sherry—not only infuses the tenderloin with a savory-sweet flavor but also serves as the foundation for a rich sauce.

The sauce is made using a technique known as “mounting.” This involves gradually whisking cold butter into the nearly completed sauce, allowing it to emulsify seamlessly. This method enriches the sauce, giving it with a glossy appearance and a luxuriously rich consistency. Pair the tenderloin with mashed sweet potatoes and French green beans for an effortlessly elegant meal.

“Easy and oh-so-flavorful!! This looks difficult but comes together in a snap. Easy to marinate in the morning and cooks up in 30 minutes in the evening.”

What You’ll Need To Make Sear-Roasted Pork Tenderloin with Mustard Glaze

pork tenderloin ingredients

Pork tenderloin is a lean and tender boneless cut of meat that is best cooked using quick, high-heat methods, such as grilling or pan-searing. Each loin weighs about one pound, so you will need two of them.

Dry sherry is a type of fortified wine that is aged in barrels and has a rich, nutty flavor. In many cuisines, it is used to add depth and complexity to sauces, stews, and marinades. Be sure to use dry sherry rather than cooking sherry or sweet sherry. Cooking sherry is a lower-quality wine that is often heavily salted, and sweet sherry, while delicious as an after-dinner drink, is too sweet to be used in cooking.

Step-by-Step Instructions

In a medium bowl, combine the brown sugar, mustard, sherry, and rosemary.

marinade ingredients in bowl

Whisk to combine.

whisked marinade in bowl

Place the tenderloins in a baking dish or bowl. Season all over with 1-1/4 teaspoons salt and pour about one-third of the marinade over top. Turn the tenderloins a few times to coat evenly with the marinade. Marinate for at least 1 hour or as long as overnight (the longer, the better). Cover the remaining marinade and refrigerate until ready to use (it will form the base of the sauce).

Heat the oil in a large cast iron or oven-safe skillet over medium-high heat and add both tenderloins.

searing the pork tenderloins

Sear on all sides until nicely browned, 6 to 8 minutes (don’t move the tenderloins around between turns; they will brown better if left alone).

browned tenderloins in skillet

Transfer the skillet to a preheated 350°F-oven and cook until the pork registers about 140°F on an instant-read thermometer, 12 to 15 minutes. (To check for doneness without a thermometer, make a slit in the thickest part of the loin; the meat should be mostly white with a slight hint of pale pink, and the juices should run mostly clear.)

Meanwhile, pour the remaining marinade into a small skillet and bring to a gentle boil over medium-high heat.

heating the reserved marinade to make sauce

Remove the pan from the heat and, stirring constantly, incorporate the butter one piece at a time. Add 1/8 teaspoon salt and a few grinds of pepper. Taste and adjust seasoning if necessary.
mounting the sauce with butter

Remove the skillet from the oven and transfer the tenderloins to a cutting board. Tent with foil and let rest for about 10 minutes, then cut into 1/4- to 1/2-inch slices.

slicing the pork tenderloin

Arrange the sliced tenderloin on a platter and drizzle with a bit of the sauce; pass the remaining sauce at the table.

Frequently Asked Questions

What is the difference between a pork tenderloin and a pork loin roast?

Pork tenderloin is a lean, slender cut typically weighing between 1 and 1.5 pounds. Renowned for its tenderness, it’s best prepared using quick, high-heat cooking methods like grilling, pan-searing, or roasting, with careful attention to avoid drying out due to its low fat content. In contrast, the pork loin roast is a larger and thicker cut, often weighing 2 to 5 pounds or more. Its higher fat content lends a richer flavor and makes it ideal for slower cooking methods such as roasting or braising.

Why does pork tenderloin often turn out dry?

Pork tenderloin can often turn out dry due to overcooking, which is a common issue given its lean nature. To prevent overcooking, it’s best to cook pork tenderloin just until it reaches 140°F and then allow it to rest for a few minutes to rise to the safe internal temperature of 145°F before slicing. This rest period also lets the juices redistribute throughout the meat. Additionally, cooking methods that involve searing the meat to lock in juices and then finishing in the oven at a moderate temperature can also help maintain tenderness.

Is it safe to eat pork that looks slightly pink when cooked?

Yes, pork is safe to eat even if it’s slightly pink, as long as it reaches the USDA’s recommended safe internal temperature of 145°F (63°C). You can remove the pork from the heat when it reaches 140°F (60°C), and let it rest for about 5 minutes. During this rest period, the internal temperature will continue to rise, or “carry over cook,” to the safe temperature. I recommend using a meat thermometer to accurately check the internal temperature.

Sear-Roasted Pork Tenderloin with Mustard Glaze

Sear-roasted pork tenderloin with a sweet mustard glaze—your ticket to an effortlessly chic dinner, any night of the week or for special occasions.

Servings: 6
Prep Time: 15 Minutes
Cook Time: 20 Minutes
Total Time: 35 Minutes, plus at least 1 hour to marinate the pork

Ingredients

  • 2 pork tenderloins (1¾ to 2 lbs total)
  • ½ cup (packed) light brown sugar
  • ½ cup grainy Dijon mustard (such as Maille Rich Country Dijon Mustard Blend or Grey Poupon Country Dijon)
  • ½ cup dry sherry
  • 1 tablespoon chopped fresh rosemary
  • Salt
  • 1 tablespoon vegetable oil, for cooking
  • Freshly ground black pepper
  • 5 tablespoons unsalted butter, cut into 5 pieces

Instructions

  1. Pat the tenderloins dry with paper towels.
  2. In a medium bowl, whisk together the brown sugar, mustard, sherry, and rosemary.
  3. Place the tenderloins in a baking dish or bowl. Season all over with 1¼ teaspoons salt and pour about one-third of the marinade over top. Turn the tenderloins a few times to coat evenly with the marinade. Marinate for at least 1 hour or as long as overnight (the longer, the better). Cover the remaining marinade and refrigerate until ready to use (it will form the base of the sauce).
  4. Preheat the oven to 350°F and set an oven rack in the middle position.
  5. Heat the oil in a large cast iron or oven-safe skillet over medium-high heat (see note below if you don't have one of these pans). Add both tenderloins and sear on all sides until nicely browned, 6 to 8 minutes (don't move the tenderloins around between turns; they will brown better if left alone). Transfer the skillet to the oven and cook until the pork registers about 140°F on an instant-read thermometer, 12 to 15 minutes. (To check for doneness without a thermometer, make a slit in the thickest part of the loin; the meat should be mostly white with a slight hint of pale pink, and the juices should run mostly clear.)
  6. Remove the skillet from the oven and immediately place an oven mitt or dishtowel over the handle to remind yourself that it is hot (it is easy to forget and burn yourself!). Transfer the tenderloins to a cutting board. Tent with foil and let rest for about 10 minutes, then cut into ¼- to ½-inch slices.
  7. Meanwhile, pour the remaining marinade into a small skillet and bring to a gentle boil over medium-high heat. Remove the pan from the heat and, stirring constantly, incorporate the butter one piece at a time. Add ⅛ teaspoon salt and a few grinds of pepper. Taste and adjust seasoning if necessary. Arrange the sliced tenderloin on a platter and drizzle with a bit of the sauce; pass the remaining sauce at the table.
  8. Note: If you don't have an oven-proof skillet, transfer the pork to a foil-lined sheet pan after searing. (The foil is just for easy cleanup.) You may need to add a few minutes to the baking time.
  9. Note: The nutritional information includes all of the ingredients for the marinade, so one serving is likely significantly lower in calories and fat than the numbers below.

  • This was wonderful, great flavors and the meat to cooking time was spot on. I love using your recipes and in general always have a great outcome typically a user error is involved. I did find this one recipe to be very sweet and dd cut it down by adding in apple cider vinegar. Will work a bit more on the sauce flavor but this is a keeper. Thanks

  • WOW! Thank you, Jenn, for another fantastic dinner recipe!! We made this late last night and had it for an early dinner tonight. DELICIOUS!!! The flavors we perfect! Tender pork! We paired it with a beautiful sauvignon blanc.

  • Made this last weekend- we loved it!!!! Added sautéed mushrooms to the sauce, delicious! Thanks for another great recipe from my fav food blogger!!

  • Hi Jenn,

    I am thinking of trying this for Christmas dinner but we will be 12. What would be the best way to at least double this? Sear in two pans and then put on baking sheet and then make sauce? Could I sear two at a time, letting the first batch rest while I sear the others and then put all of them in the oven? Any tips would be appreciated. LOVE your new cookbook!

    • Hi Hella, I would sear two at a time, letting the first batch rest while you do the second, then put them all in the oven. (They will take a bit longer in the oven.) So glad you’re enjoying the new book. 🙂

  • This is definitely a guest-worthy dish. AND so so so easy. I didn’t realize that the recipe required an hour-long marinade and on a weeknight, that wasn’t possible, so I just seared the four sides of the tenderloin with oil, salt, and pepper in a cast iron skillet–two minutes on each side, and then I poured the “marinade” as a sauce over the whole thing and stuck it in the 425 oven for about 20 minutes until the meat temp was 145. Really moist and flavorful and the searing gave it a decent crust.
    Literally a 5 minute prep to mix the sauce, then 10 minutes on the stovetop rotating as the sides get seared, and then in the oven for 20 minutes or so. Thank you again, Jenn! I don’t think anyone can mess this one up!

  • Hi my favourite Chef …I have had little success with pork tenderloin in the past. With cost of food we need to be more aware and economic in our meals. This fits the bill. Best pork tenderloin ever. I have followed you for a few years and have both your books. You make my life so much easier and tastier. Happy Holidays from a big fan 🥰

  • We love this recipe ! It took a minute to make the marinade. I left the pork in the fridge overnight. It took less than 20 minutes to fix dinner and I came out looking like a hero ! Thanks !

    • I made this for guests. I have tried so many of your recipes that I have confidence they will be great. I got rave reviews and many requests for the recipe! I served it with a mushroom farroto. Lovely combination

  • Another 6 star recipe (my husband gave it 10 stars)—flavors and textures beautifully balanced—We served with Jenn’s maple mashed sweet potatoes and green beans—WOW!

  • Thought it was perfect as all the recipes on Jenn’s site!

  • Hello,
    I can’t find the Maille country Blane mustard or the Grey poupon in Canada? Should I use the Maille old fashioned mustard?

    • Hi Lucie, I think that should work – any grainy mustard would be fine here.
