Korean Pork Tenderloin with Soy-Gochujang Glaze

This Korean-inspired pork tenderloin is seared, roasted, and coated with a glossy sauce of gochujang, soy, garlic, ginger, and pear. It is a flavorful weeknight main that slices neatly for rice bowls, lettuce wraps, or a shared platter; the sweet-spicy balance can be adjusted to suit your table.

Ingredients

1 pork tenderloin, about 1½ lb (680 g), silver skin trimmed
3 tbsp (45 ml) low-sodium soy sauce
2 tbsp (36 g) gochujang, Korean fermented chile paste
1 tbsp (21 g) honey
1 tbsp (15 ml) toasted sesame oil
1 tbsp (15 ml) rice vinegar
½ cup (75 g) finely grated ripe Asian pear, including its juice
3 garlic cloves (9 g), finely grated or minced
1 tbsp (6 g) finely grated fresh ginger
¼ tsp (0.5 g) freshly ground black pepper
1 tbsp (15 ml) neutral oil, such as canola, for searing
1 tsp (3 g) toasted sesame seeds, for serving
2 medium scallions (30 g), thinly sliced, for serving

Instructions

Whisk the soy sauce, gochujang, honey, sesame oil, rice vinegar, grated pear, garlic, ginger, and black pepper in a bowl until the gochujang is mostly dissolved. Set aside ¼ cup (60 ml) of this mixture in a clean, covered container for the finishing sauce. Do this before the pork touches the marinade so the reserved portion stays uncontaminated.
Pat the tenderloin dry with paper towels and trim away any tough silver skin with a small sharp knife. Put the pork in a shallow dish or zip-top food-safe bag and pour the remaining marinade over it. Turn the meat to coat, cover, and refrigerate for 30 minutes. If you need to wait longer, keep it chilled and cook within 2 hours for the best texture; the pear and soy can make a long marinade overly soft or salty. While it marinates, heat the oven to 425°F (220°C) and let the pork sit out only while you prepare the pan.
Remove the tenderloin from the marinade and let excess liquid drip off; discard the marinade that touched the raw pork. Pat the surface lightly so it can brown rather than steam. Heat an oven-safe skillet over medium-high heat, add the neutral oil, then sear the tenderloin for about 1½ to 2 minutes on each side, turning until most of the surface is browned. If you do not have an oven-safe skillet, transfer the seared pork to a small rimmed baking sheet.
Transfer the skillet or baking sheet to the oven. Roast for about 12 to 16 minutes, turning once if the tenderloin is unevenly shaped, and begin checking the thickest part after 10 minutes. The USDA FSIS safe minimum for whole cuts of pork is 145°F (63°C), checked with a food thermometer, followed by a rest of at least 3 minutes. Do not judge doneness by color alone; a slight blush can remain at this safe temperature.
While the pork roasts, pour the clean reserved sauce into a small saucepan and bring it to a boil over medium heat. Boil for 1 minute, stirring, then lower the heat and simmer until lightly thickened, about 1 to 2 minutes more. Keep it separate from the used marinade and use a clean spoon for tasting. If the sauce becomes too thick to brush, loosen it with 1 teaspoon (5 ml) of water at a time.
Move the pork to a clean cutting board and rest it for at least 3 minutes. Brush or spoon some of the warm sauce over the top, then slice across the grain into medallions about ½ inch (1.3 cm) thick. Arrange on a platter, spoon over any sauce left in the pan that has not contacted raw pork, and finish with sesame seeds and sliced scallions. Serve the remaining sauce at the table.

Tips

Trim silver skin, but do not cut away every bit of fat. Silver skin stays tough after cooking, while a little surface fat helps protect the tenderloin from drying out. Tenderloin is narrow and lean, so check it early rather than relying only on the clock.
Gochujang is a Korean fermented chile and soybean paste, not simply a hot sauce; it brings savory depth, sweetness, and heat. If it is hard to find, mix 1 tablespoon (18 g) miso with 1 tablespoon (15 ml) sriracha and 1 teaspoon (7 g) honey as a stand-in. The flavor will be less distinctly fermented and may be hotter, so taste the sauce before adding extra chile.
Asian pear gives the marinade a gentle fruit sweetness and a little body. A crisp apple is a practical substitute in the same quantity, although the result will taste less floral. If neither is available, use ¼ cup (60 ml) unsweetened apple juice; the marinade will be thinner, so pat the pork especially well before searing.
For clean slices, use a sharp knife and cut across the direction of the muscle fibers. Keep the thermometer probe in the center of the thickest section, not against the pan or in a shallow end. A dark exterior is welcome, but if the glaze begins to scorch in the skillet, move the pork to the baking sheet before roasting.

Serving Suggestions

Serve the sliced pork with steamed short-grain rice, which catches the sweet-salty sauce, and a crisp vegetable such as cucumber, shredded cabbage, or lightly dressed greens. For a rice bowl, add the pork over rice with quick-pickled cucumber, shredded carrot, and a spoonful of sauce; keep the vegetables fairly plain so the gochujang glaze remains the main flavor. A bowl of kimchi makes a sharp, tangy contrast if you enjoy it, but it is not required.

For a hands-on meal, set out lettuce leaves, rice, pork slices, scallions, and a little extra sauce so everyone can assemble wraps. Thinly sliced radish or cucumber adds crunch. If serving a larger spread, pair the pork with roasted broccoli or green beans and a mild soup. The tenderloin is rich in flavor but lean, so a bright or crunchy side helps balance the plate rather than adding another heavy sauce.

Variations

To make the dish milder, reduce the gochujang to 1 tablespoon (18 g) and add 1 tablespoon (21 g) more honey. That softens the chile heat while keeping some fermented savoriness. For a hotter version, stir ¼ to ½ teaspoon (0.5 to 1 g) gochugaru, Korean red pepper flakes, into the marinade. Gochugaru is often sold in Korean grocery stores; crushed red pepper flakes can substitute, but they are sharper and less fruity, so start with a small amount.

You can also use the same marinade with pork loin chops, but they cook faster and need individual temperature checks. Do not substitute a large pork loin roast without changing the roasting plan: its thickness and cooking time differ substantially from tenderloin. For a slightly smoky finish, grill the tenderloin over medium-high direct heat, turning it to brown all sides, then move it to indirect heat until it reaches the same safe internal temperature. Keep a clean plate ready for the cooked meat and never reuse the raw-pork marinade unless it has been boiled.

Storage and Reheating

Refrigerate cooked pork within 2 hours of cooking, in a shallow airtight container with any leftover sauce kept alongside it. It keeps for 3 to 4 days in the refrigerator. For longer storage, freeze the sliced pork and sauce in a freezer-safe container for up to 2 to 3 months for best quality; thaw it in the refrigerator rather than on the counter. The texture may be a little less juicy after freezing, so storing the slices with sauce helps.

Reheat only the portion you plan to eat. Add a teaspoon or two of water to the pork and sauce, cover, and warm gently in a skillet over low heat, turning the slices once. You can also microwave it covered in short intervals, stirring or rearranging the slices between intervals. Reheat leftovers to 165°F (74°C), checked with a food thermometer. Avoid prolonged high heat, which can dry out this lean cut. If the pork smells off or has been left out longer than 2 hours, discard it rather than tasting it.

Frequently Asked Questions

Can I marinate the pork overnight?
It is better not to leave this tenderloin in the pear-and-soy marinade overnight. The salt can make the meat taste too seasoned, and the fruit can soften the surface. Thirty minutes gives the flavor time to cling, and up to 2 hours in the refrigerator is a reasonable upper limit for this recipe. For advance prep, mix the sauce a day ahead, refrigerate it, and marinate the pork shortly before cooking.

Can I cook it without searing first?
Yes. Put the marinated tenderloin on a lined rimmed baking sheet and roast at 425°F (220°C), checking the thickest point with a thermometer. It may take a few minutes longer than the seared version and will have less browned flavor, but it will still work. Discard the used marinade and use the separately reserved, boiled sauce for serving.

Why did my pork turn out dry?
The most common reason is cooking past the recommended temperature, especially because tenderloin is lean and continues to cook slightly as it rests. Check the center early and remove the pork when it reaches 145°F (63°C), then give it the required 3-minute rest. Also make sure the thermometer is placed in the thickest part; a reading from the narrow tip can be misleading.

Is gochujang very spicy?
Its heat varies by brand and style, but it is usually more rounded and savory than a plain chile sauce. The honey and pear mellow this recipe without removing the chile flavor. Start with 1 tablespoon if you are sensitive to heat, then serve additional sauce separately so each person can choose how much to use.

Can I make the sauce ahead?
Yes. Whisk the sauce ingredients together and refrigerate them in a covered container for up to 2 days. Before using it as a marinade, stir well because the pear can settle. Reserve the portion for brushing before adding the raw pork, and boil that clean portion as directed; never use the uncooked marinade that has contacted raw meat as a finishing sauce.
