Marinated pork tenderloin is a lean, mild cut flavored with a quick soy, honey, garlic, and mustard marinade, then roasted until juicy. At 400°F (200°C), a 1- to 1½-pound tenderloin usually takes about 20–25 minutes; use a thermometer rather than time alone to know when it is ready.
Ingredients
- 1 pork tenderloin, about 1¼ lb (570 g), silver skin trimmed
- 2 tbsp olive oil (30 ml)
- 2 tbsp reduced-sodium soy sauce (30 ml)
- 1 tbsp apple cider vinegar (15 ml)
- 1 tbsp honey (21 g)
- 1 tbsp Dijon mustard (15 g)
- 2 garlic cloves, finely grated or minced (about 6 g)
- ½ tsp smoked or sweet paprika (about 1 g)
- ¼ tsp freshly ground black pepper (about 0.5 g)
- ¼ tsp fine salt (about 1.5 g)
Instructions
- Trim and check the tenderloin. Pat the pork dry and remove any silvery membrane along the surface with a small sharp knife; it can remain tough after cooking. If the tenderloin has a very thin tail, tuck it underneath and tie it loosely with kitchen twine so the meat cooks more evenly. This recipe is for pork tenderloin, a narrow, tender muscle, not pork loin, which is much larger and needs a different cooking time.
- Make the marinade. In a small bowl, whisk together the olive oil, soy sauce, vinegar, honey, Dijon, garlic, paprika, pepper, and salt. The mixture should taste savory, lightly sweet, and tangy. If you prefer a less salty result, use low-sodium soy sauce as listed and do not add extra salt; soy sauces vary in saltiness.
- Marinate in the refrigerator. Put the pork in a shallow dish or a food-safe resealable bag and pour the marinade over it, turning to coat. Cover the dish or seal the bag and refrigerate for 2 hours. Turn the meat once if convenient. It can marinate for up to 8 hours, but do not leave it at room temperature. The vinegar adds flavor; a much longer soak is not needed and can make the outside of the meat soft.
- Heat the oven and prepare the pan. Toward the end of the marinating time, heat the oven to 400°F (200°C). Set a rack in the center and line a rimmed baking sheet or small roasting pan with foil for easier cleanup. Lift the pork out of the marinade and let excess drip off. Discard the used marinade, since it has been in contact with raw pork. Arrange the tenderloin on the pan; it does not need to come to room temperature first.
- Roast until it reaches temperature. Roast for about 20–25 minutes, turning the tenderloin once halfway through if one side is browning much faster. Begin checking at 18 minutes because ovens and tenderloin thickness vary. Insert an instant-read food thermometer into the thickest part, from the side if that makes it easier to get the probe centered. The USDA FSIS safe minimum for a whole cut of pork is 145°F (63°C), followed by a 3-minute rest. Remove the pork when the center reaches 145°F (63°C); do not rely on the outside color or a fixed timer to judge doneness.
- Rest, slice, and serve. Transfer the tenderloin to a clean cutting board and rest it for at least 3 minutes before slicing across the grain into medallions. The center may be slightly pink at the safe temperature, which is normal. Spoon any juices from the pan over the slices. For the recipe timing, allow about 22 minutes of roasting and a 3-minute rest; start checking early so the pork does not overcook.
Tips
- Use the thermometer in the thickest section. Tenderloins often taper at one end, so a probe placed too near the thin tip can give a misleadingly high reading. Check the thick center and, if the roast is irregular, check a second spot. Pull it at 145°F (63°C) and give it the full 3-minute rest.
- Keep the raw marinade separate from serving sauce. Do not spoon marinade that touched uncooked pork over the finished meat. If you want extra sauce, set aside a few tablespoons before adding the pork, keep that portion covered in the refrigerator, and serve it as is or warm it separately. Never reuse the contaminated marinade unless it is thoroughly brought to a boil.
- Adjust the salt thoughtfully. Regular soy sauce can make the marinade saltier than intended. Use reduced-sodium soy sauce, or reduce the added salt if your sauce is especially salty. Tamari works as a gluten-free substitute when labeled gluten-free; it gives a similar savory flavor, though the exact salt level differs by brand.
- Give the meat room in the pan. If roasting two tenderloins, leave space between them and check each one separately. Crowding traps moisture and can slow browning. Tenderloins also vary in thickness, so one may finish several minutes before the other.
Serving Suggestions
Slice the rested pork into medallions and serve it with the pan juices while warm. The sweet-savory marinade pairs well with roasted potatoes, rice, couscous, or buttered noodles, all of which can catch the juices. For a lighter plate, add green beans, broccoli, sautéed greens, or a crisp salad dressed with a tart vinaigrette. A simple apple slaw or roasted apples also suits the pork’s gentle sweetness without requiring another rich sauce.
If you are serving a group, keep the tenderloin whole until shortly before eating, then slice it across the grain. This helps the cut retain its juices and makes it easier to arrange on a platter. Put any sauce or pan juices in a small serving dish rather than letting the meat sit in liquid for a long time. For a meal-prep lunch, pair a few cooled slices with cooked grains and vegetables, and keep the components chilled until serving.
Variations
Citrus-herb: Replace the cider vinegar with 1 tablespoon (15 ml) lemon juice and add 1 teaspoon (1 g) dried oregano or 1 tablespoon (about 3 g) chopped fresh rosemary. The flavor becomes brighter and more herbal. Keep the marinade time the same, and still cook by internal temperature.
Ginger and sesame: Add 1 teaspoon (5 g) finely grated fresh ginger and replace the olive oil with a neutral oil. After cooking, finish the sliced pork with 1 teaspoon (5 ml) toasted sesame oil and sliced scallions if you like. Sesame oil is best as a finishing flavor rather than the main roasting oil.
Less sweet or no honey: Omit the honey for a sharper, more savory marinade, or replace it with 1 tablespoon (15 ml) maple syrup. Without a sweetener, the surface will brown a little less and the vinegar and mustard will stand out more. Do not add extra vinegar to compensate, because too much acid can overwhelm the meat.
Grilled version: For a charcoal or gas grill, cook the marinated tenderloin over medium heat with the lid closed, turning every few minutes so it browns evenly. It often takes roughly 12–18 minutes, depending on grill heat and thickness, but use the same thermometer target of 145°F (63°C) and a 3-minute rest. Grill timing is less predictable than oven timing, so the temperature reading is essential.
Storage and Reheating
Refrigerate cooked pork within 2 hours of cooking, in a shallow airtight container. It keeps for 3–4 days in the refrigerator. If you expect leftovers, slice only what you plan to serve and store the rest of the tenderloin in larger pieces; larger pieces are less likely to dry out when reheated. Keep the pan juices with the pork if available, or add a spoonful of broth or water before reheating.
For a gentle reheat, warm slices in a covered skillet over low heat with a little liquid, turning once, or microwave them in a covered dish in short bursts. Reheat leftovers to 165°F (74°C), checking with a food thermometer. The pork can also be frozen in a well-sealed freezer container for about 2–3 months for best quality; thaw it in the refrigerator before reheating. Do not leave cooked pork at room temperature for more than 2 hours, or more than 1 hour when the room or outdoor temperature is above 90°F (32°C).
Frequently Asked Questions
How long does marinated pork tenderloin take to cook?
At 400°F (200°C), plan on about 20–25 minutes for a 1- to 1½-pound tenderloin, then rest it for at least 3 minutes. Thickness, starting temperature, and oven differences affect the time, so begin checking at 18 minutes and use a thermometer. The reliable endpoint is 145°F (63°C) in the thickest part.
Can I marinate pork tenderloin overnight?
You can refrigerate it in this marinade for up to about 8 hours. Two hours gives the flavor time to develop, while a much longer soak is unnecessary and the vinegar may soften the surface. If you need to prep farther ahead, mix the marinade in advance and keep it separate from the pork until the day you cook it.
Should I rinse the marinade off before cooking?
No. Lift the tenderloin from the dish and let excess marinade drip away; rinsing raw meat can spread splashes around the sink and does not improve safety. Discard the used marinade, patting the surface lightly only if it is very wet. A thin coating of marinade can remain and will season the exterior as it roasts.
Why is my pork tenderloin dry?
The most common reason is cooking it too long. Tenderloin is lean, so several extra minutes can noticeably dry it out. Check the thickest part with a thermometer, remove it at 145°F (63°C), and allow the required 3-minute rest. Also slice across the grain and avoid holding the cooked meat uncovered for an extended time.
Can I use pork loin instead?
Pork loin is a different, wider cut and will not follow this recipe’s timing. The marinade works as a flavoring for loin, but roast it according to its thickness and check its center with a thermometer rather than using the tenderloin estimate. For this recipe as written, choose a pork tenderloin weighing about 1¼ pounds (570 g).
