Grilled pork tenderloin is a lean, tender cut brushed with a savory-sweet maple, Dijon, and garlic marinade, then cooked over a two-zone grill and sliced for serving. The method pairs a quick sear with gentler indirect heat, helping the pork brown without drying out; the flavors are familiar, flexible, and easy to match with summer sides.
Ingredients
- 1 pork tenderloin, about 1 1/4 pounds (565 g), silver skin removed
- 1 tablespoon olive oil (15 ml)
- 2 tablespoons low-sodium soy sauce (30 ml)
- 1 tablespoon pure maple syrup (15 ml)
- 1 tablespoon Dijon mustard (15 g)
- 1 tablespoon apple cider vinegar (15 ml)
- 2 garlic cloves, finely grated or minced, about 2 teaspoons (6 g)
- 1 teaspoon smoked paprika (2 g)
- 1/2 teaspoon kosher salt (about 3 g; use a little less if using fine table salt)
- 1/2 teaspoon freshly ground black pepper (about 1 g)
- 1 teaspoon finely chopped fresh rosemary (about 1 g), optional
Instructions
- Trim and mix the marinade. Pat the pork dry with paper towels. If a thin, silvery membrane remains along the tenderloin, slide a small sharp knife just under it and trim it away; it can turn chewy on the grill. In a small bowl, whisk together the olive oil, soy sauce, maple syrup, Dijon, vinegar, garlic, paprika, salt, pepper, and rosemary, if using. Before the marinade touches raw pork, spoon 2 tablespoons into a separate clean dish and refrigerate it for serving.
- Marinate the pork. Put the tenderloin in a shallow dish or a food-safe resealable bag and pour the remaining marinade over it. Turn the pork so it is coated, cover or seal, and refrigerate for 30 minutes. This short rest gives the surface time to pick up flavor; it is not necessary to leave a lean tenderloin in an acidic marinade for hours. Keep raw pork and its marinade away from ready-to-eat foods.
- Set up a two-zone grill. Heat a gas grill with one side on medium-high and the other side on low, or arrange charcoal on one side of a charcoal grill so the other side is cooler. Aim for roughly 400–450°F (204–232°C) with the lid closed. Clean the grates and lightly oil them using a folded paper towel held with tongs. A cooler zone is important: it gives you a place to finish cooking if the outside browns before the center is ready.
- Sear, then finish over indirect heat. Lift the pork from the marinade and let excess drip back into the dish; discard the marinade that touched raw meat. Place the tenderloin over the hot zone and sear for about 2 minutes per side, turning with tongs to brown the long sides as well. Move it to the cooler side, close the lid, and grill for about 7–10 minutes, turning once. The exact time depends on the tenderloin’s thickness and the grill, so begin checking early rather than relying on the clock.
- Check temperature and rest. Insert an instant-read food thermometer into the thickest part of the tenderloin, approaching from the side if that makes it easier to reach the center. The USDA FSIS safe minimum for a whole cut of pork is 145°F (63°C), followed by a 3-minute rest; cook until the thickest point reaches that temperature. If it needs more time, keep it over indirect heat and check again after a few minutes. Transfer the pork to a clean cutting board and let it rest for at least 3 minutes before slicing.
- Slice and serve. Cut the tenderloin crosswise into slices about 1/2 inch (1.3 cm) thick. Spoon or brush on the reserved clean marinade, or serve it at the table. If you want a warmer sauce, heat the reserved marinade in a small saucepan until steaming, then drizzle it over the pork. Use a clean platter and utensils for the cooked meat.
Tips
- Check the label before seasoning. Tenderloins are sometimes sold enhanced with a salt solution, and soy sauce already contributes salt. If yours is labeled seasoned or brined, omit the added kosher salt or reduce it to a pinch. For a gluten-free version, choose certified gluten-free tamari in place of soy sauce; it gives a similarly savory flavor, though its saltiness varies by brand.
- Keep the meat whole while grilling. Cutting the tenderloin into medallions before cooking exposes more surface area and makes it easier to overcook. Grill it whole, use the thermometer in the thickest section, and slice only after resting. Tenderloins are not perfectly even, so a thinner end may finish first; move it toward the cooler edge if it is browning quickly.
- Control flare-ups instead of chasing them. A little dripping is normal, but flames can char the sugary maple coating. Keep the lid closed when possible, use the indirect zone when flames flare, and avoid pressing the meat against the grate. If the grill temperature is running hot, lower the gas setting or open the lid briefly while moving the pork to the cooler side.
- Make substitutions with the flavor in mind. Honey can replace maple syrup in the same amount and makes the glaze taste more floral and slightly less woodsy. If you do not have smoked paprika, use sweet paprika for color and mild pepper flavor, but expect less smokiness. Dried rosemary is stronger than fresh, so use about 1/4 teaspoon (0.3 g) instead of the fresh amount.
Serving Suggestions
Serve the slices warm with grilled vegetables, corn on the cob, or a simple green salad. The maple-Dijon glaze also works well beside potato salad, roasted potatoes, rice, or a grain such as farro; choose one hearty side and one crisp or fresh side for a balanced plate. If the pork is part of a cookout, grilled zucchini, bell peppers, or asparagus can share the grill. Start vegetables that need longer cooking first, then grill the tenderloin while they finish over the cooler zone.
For a more substantial meal, tuck thin slices into rolls with crunchy slaw, or add them to a bowl with rice, greens, and sliced cucumber. The reserved sauce is concentrated, so begin with a small drizzle and add more to taste rather than soaking the slices. A lemon wedge or a little chopped parsley can brighten the plate, especially if the sides are rich. Slice only the amount you plan to serve right away; keeping the remaining tenderloin whole helps it stay moist for leftovers.
Variations
Herb and lemon: Replace the smoked paprika with 1 teaspoon (2 g) dried oregano and add 1 teaspoon finely grated lemon zest (about 2 g) to the marinade. This gives the pork a brighter, more herbal profile. Keep the vinegar in the recipe, or use lemon juice in its place for a sharper citrus note. The overall method and safe temperature remain the same.
Ginger-soy: Swap the rosemary for 1 tablespoon finely grated fresh ginger (about 6 g) and add 1 teaspoon toasted sesame oil (5 ml). Use honey or maple syrup for sweetness. Serve with rice and sliced scallions if you like; this variation is inspired by familiar savory-sweet flavors rather than a claim to one regional tradition. If using regular soy sauce instead of low-sodium, taste the reserved sauce before adding any extra salt.
Spicy version: Add 1/4 teaspoon (about 0.5 g) cayenne pepper or 1 teaspoon (5 ml) chili paste to the marinade. Start with the smaller amount if you want only gentle heat, since chili pastes differ in strength and saltiness. For a fruitier, less smoky finish, use sweet paprika instead of smoked paprika and serve with a crisp slaw.
No outdoor grill: The grill flavor will be different, but you can use a grill pan on the stovetop and finish the tenderloin in a 400°F (204°C) oven. Sear it on all sides in an oven-safe pan, then roast until a thermometer reads 145°F (63°C) in the thickest part and rest for 3 minutes. Cooking time in an oven varies with the cut’s size, so temperature—not a fixed number of minutes—is the reliable guide.
Storage and Reheating
Refrigerate cooked pork within 2 hours of grilling, storing it in a shallow airtight container. It keeps for 3–4 days in the refrigerator. For the best texture, store leftover tenderloin whole or in large pieces and slice it just before serving. Keep any sauce separate, and do not save marinade that has been in contact with raw pork unless it was thoroughly boiled before serving.
To reheat, place slices in a covered skillet with a spoonful of water, broth, or reserved sauce and warm over low heat until hot, turning once. You can also microwave portions in a covered dish in short bursts, stirring or rearranging between bursts so they heat evenly. USDA FSIS guidance is to reheat leftovers to 165°F (74°C); check the center with a food thermometer. Reheating can make lean pork dry, so use gentle heat and stop as soon as it reaches that temperature. Freeze portions in airtight packaging for up to 2–3 months for best quality, then thaw in the refrigerator before reheating.
Frequently Asked Questions
How long does pork tenderloin take on the grill?
A tenderloin around 1 1/4 pounds (565 g) often takes about 12–15 minutes of grilling after the grill is hot, including searing and finishing over indirect heat. Thickness, starting temperature, and grill design all affect the timing. Use the clock as a guide, but check the center with an instant-read thermometer and follow the 145°F (63°C) safe minimum plus a 3-minute rest.
Should I grill pork tenderloin with the lid open or closed?
Keep the lid closed while the pork finishes over indirect heat so the grill cooks more evenly and holds its temperature. Open it to turn the tenderloin, check for flare-ups, or use the thermometer. On a gas grill, the cooler side should remain off or on low; on charcoal, leave a clear space without coals for indirect cooking.
Can I marinate the pork overnight?
You can refrigerate it longer, but this recipe is designed for a 30-minute marinade. Because it contains vinegar and mustard, a very long soak may soften the surface without adding much benefit. If you need to prep ahead, mix the marinade and trim the pork earlier, then combine them shortly before grilling. Always marinate in the refrigerator, not on the counter.
Can I use pork loin instead of tenderloin?
They are different cuts and are not a direct, same-time substitute. Pork loin is wider and thicker, so it generally needs a different cooking time and may require a longer indirect finish. You can use the same flavor combination, but check the center with a thermometer and cook whole-cut pork to 145°F (63°C), followed by a 3-minute rest.
Why is my grilled pork tenderloin dry?
The most common reason is cooking it past the safe minimum temperature or leaving it over direct heat too long. Tenderloin is lean, so use the indirect zone after searing and start checking its temperature early. Let it rest for 3 minutes, then slice across the grain; thin slices cut against the grain are easier to chew and retain their juices better on the plate.
Can I prepare the marinade in advance?
Yes. Mix the marinade without the pork and keep it covered in the refrigerator for up to 2 days. Reserve the clean portion for serving before adding any marinade to raw meat. If you forget to reserve some, do not use the pork-contact marinade as a finishing sauce unless you bring it to a full boil first; the simplest option is to make a fresh small batch.
