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.
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.

What You’ll Need To Make Sear-Roasted Pork Tenderloin with Mustard Glaze
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.
Whisk to combine.
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.
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 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. 
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.
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.
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
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.
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.
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.
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
- Pat the tenderloins dry with paper towels.
- In a medium bowl, whisk together the brown sugar, mustard, sherry, and rosemary.
- 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).
- Preheat the oven to 350°F and set an oven rack in the middle position.
- 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.)
- 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.
- 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.
- 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.

I love all your recipes – you are one of my “go to” blogs! I marinate the pork tenderloins in ziplock bags and then freeze to bring on our Cape Cod beach vacation. We grill the pork & warm up the glaze on the stove – delicious! And easy!
Wonderful. This is my go to for an easy entertainment meal. I paired it with the sweet potatoes, summer salad and strawberry cake!
Jenn, This dish is delicious! Thank you! My family loved it! It was easy and not expensive! I used white wine as the grocery store did not have sherry. I got the pork on sale so it was a win-win! Thank you!
I knew I wanted to make this in the slow cooker, for ease, I was a bit worried about the amount of sugar, as I don’t really have a sweet tooth, so I halved it. The family loved the taste, but thought it really sweet, so I could probably really reduce the sugar to much less, but the underlying flavour was really tasty. It worked really well in the slow cooker. Thanks again fif a great recipe 👍 😋
I make marinated seared tenderloins finished in the oven all of the time. I’m on a quest for THE perfect recipe. Wow, this one is right up there and is the best we’ve had so far! I love mustard, but not when it’s too spicy or overpowering. I was surprised at the quantity of 1/2 cup (I used Dijon), but it was well-balanced with the brown sugar and sherry. The sauce is buttery gorgeous. Slow cooker sweet potatoes and steamed green beans were a perfect complement. My husband and I loved it, and we think that it is restaurant worthy! Thanks, Jean!
Very tasty! I’ve had this recipe on file to try for awhile now.
The pork was wonderfully tender. Folks that cook it to 160 F don’t know what they’re missing. 145 F meets food safety concerns.
I paired the pork with a recipe on food.com for sheet pan potatoes and shallots w/balsamic vinegar/EVOO/rosemary baked at 350 F. I love cast iron for searing meat. However it heats unevenly on a stovetop. I often preheat cast iron skillets in the oven to address this . This side was perfect for this, as the potato/shallot dish took an hour to roast, giving me plenty of time to heat the skillet and prepare the tenderloins.
Hi Jenn,
First, thank you for this site! I’ve made and loved many of your recipes. I’m planning to try this pork tenderloin recipe for company, and I was wondering two things: could I substitute the regular Maille Dijon for the grainy? And do you think I could cut the sugar back some and add some a bit near the end of cooking if it seems to be missing? Just a personal preference for less-sweet things.
Yes and yes (and so glad you like the recipes) – hope you enjoy this one as well!
I don’t like mustard. Is there anything I can use as a substitute?
Hi Cindy, mustard plays a pretty big role in this marinade, so if you don’t like it, I think you’d be better off using a different recipe/marinade. Sorry!
Hi Jenn – How long can I marinade without ruining.the tenderloin?
Hi Danneen, I’d limit it to 2 days.
I might have missed it somehow but the pork should be marinated in the refrigerator, right? “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). ” It might be a good idea to be specific, especially for beginners.
Hi Tory, Yes, the pork should be marinated in the refrigerator. Sorry if that wasn’t clear – I’ll begin to add that to recipes that require marinating. Hope you enjoy the dish!
