👨🍳 Quick Overview: Grilling Pork Tenderloin on a Gas Grill
Grilled pork tenderloin cooks fast—about 25 minutes on a gas grill at 450°–500°F. Below is the quick step-by-step, with full details in the recipe card.
1. Trim and prep
Trim off the silver skin and any excess fat.
✅ Pro Tip: To remove silver skin, slide a finger or the back of a butter knife under it to loosen, then use a sharp knife for the tougher spots.
2. Optional brine and season
Brine for 1–2 hours if desired, then rinse well. Pat dry and season with salt, pepper, or your favorite rub.
3. Grilling
Place on a preheated grill at 450°–500°F. Close the lid and rotate ⅓ every 5 minutes. Cook to an internal temp of 145°—about 25 minutes total.
✅Pro Tip: Pork tenderloin is shaped like a triangle. Flip it one-third of a turn each time to cook all sides evenly.
✅ Pro Tip: Always cook to temperature, not time. Use an instant-read thermometer for perfect doneness. Remember, the temperature will rise a few degrees during the rest period.
4. Rest before slicing
Tent with foil and rest for 5–10 minutes so the juices reabsorb. Then slice across the grain and serve.

⏲️ How Long to Grill Pork Tenderloin on a Gas Grill
Grilingl a 1½-pound pork tenderloin over direct heat at a surface temperature of 450°F, and it will take about 25 minutes to reach an internal temperature of 145°F (medium-rare). Smaller tenderloins (1¼ lb) may cook 5–8 minutes faster, while larger ones (1¾ lb) could take 5–10 minutes longer.
Estimated grill times at 450°F for a 1½-pound tenderloin:
- Rare (<145°F) – Not recommended (USDA safety guidelines).
- Medium-Rare (145°–150°F) – A little pink. About 22–27 minutes. My go-to and highly recommended.
- Medium (150°–155°F) – Around 27–30 minutes. My wife's choice.
- Medium-Well (155°–160°F) – Takes roughly 29–32 minutes. Fine, if you’re sure.
- Well Done (160°F+) – Not recommended—tends to be dry and tough.
Reminder: These times are just a planning guide—always cook to an internal temperature, not by the clock. The temperature will rise 2° to 4°F after removing it from the grill.
✅ Pro Tip: According to the USDA, pork is safe to eat at 145°F (medium-rare)—even if it’s a little pink inside. Just be sure to rest the meat for about 3 minutes before slicing.

🌡️ Grill Temperature for Pork Tenderloin
The best grill surface temp for pork tenderloin is 450°–500°F (medium-high). Combine this with a final internal temp of 145°F for juicy, safe results.
- A grill surface thermometer tells you the actual temperature where the pork is cooking, not just what the hood says.
- An instant-read thermometer checks doneness by measuring the internal temperature of the meat.
- Together, they take the guesswork out of grilling.
Need help learning how to read or manage grill temperatures? See my full Guide to Grill Temperature on a Gas Grill for details on surface heat, burner settings, and troubleshooting.
🥣 Seasoning/Marinades
Just coarse salt and black pepper are enough to make pork tenderloin shine. I often use my All Purpose Seasoning - 7:2:1 and 7:2:2, made with salt, pepper, and garlic powder. You can also go with a pork rub like BBQ Dry Rub or Southwest Chipotle Seasoning—really, any seasoning blend you like will work.
For something special, try a marinade like my Balsamic Pork Tenderloin or Alton Brown's Chipotle Lime Pork Tenderloin. Want to level it up with flavor? Add a glaze, like my Honey Garlic Pork Tenderloin, or go full BBQ with my Memphis BBQ Pork Tenderloin—a favorite for a reason.
🤔 Troubleshooting: How to Fix Common Pork Tenderloin Problems
If your grilled pork tenderloin isn’t turning out right, most issues come down to grill or meat temperature — so check those sections above first.
Here’s how to fix the other common problems:
- Excessive char: Flip more often and lower the grill temperature a bit.
- Flare-ups: Avoid flare zones and trim visible fat before grilling.
- Undercooked center: Use a slightly lower grill temp for gentler, more even cooking.
- Dry pork: Usually from one of two causes:
- Overcooking: Always cook to 145°F and check with a thermometer.
- Freezer damage: Pork that’s been frozen too long can lose moisture. A short brine helps, but starting with fresh meat is best.
🍽️ Serving Grilled Pork Tenderloin
Let the grilled pork tenderloin rest off the heat for 5 to 10 minutes so the juices reabsorb. Then slice across the grain for the most tender results.
We usually serve it plain or with a little Memphis BBQ sauce, but it also works well with a glaze or light drizzle of pan sauce.
If you’re pairing, a light red wine (like Pinot Noir) or a dry white (like Sauvignon Blanc) goes great with grilled pork.
Sides? Totally optional. But if you’re looking:
- Vegetables: Grilled Mixed Vegetables, Grilled Corn, Grilled Asparagus.
- Potatoes: Grilled Little Potatoes, Grilled French Fries
- Salad: Fresh garden salad, Fresh Spinach Salad, Caprese Pasta Salad, Classic Macaroni Salad.
- Dessert: Brown Sugar Cinnamon Glazed Grilled Pineapple, Fresh Strawberry Pie.
❄️ Leftovers
Store leftovers in an airtight container in the refrigerator for up to 4 days, or freeze for up to 3 months.
Reheat gently in the microwave on medium power so it stays tender. Or skip the heat: sliced cold pork tenderloin makes a great topping for a green salad or sandwich.
❓ FAQs
Yes. According to the USDA, pork is safe to eat at 145°F with a 3-minute rest—even if it’s slightly pink inside. That’s medium-rare and perfectly safe when cooked to the right temperature.
What temperature should I grill pork tenderloin?
Use medium-high heat with a grill surface temperature of 450°–500°F over direct heat. Rotate every ~5 minutes and cook to an internal 145°F, then rest 5–10 minutes. Times vary by size—always cook to temperature, not time.
It’s optional. Pork tenderloin is already tender and moist, but brining can help if it's been frozen. A good basic brine: 1 tablespoon kosher salt per cup of water. You can add an equal amount of sugar and toss in garlic or herbs for more flavor.
Brine in the fridge for 1 to 2 hours, rinse under running water, and pat dry. Don’t add extra salt when seasoning if you brine.
No need. This direct heat method gives faster results, great char, and juicy meat with less hassle. I’ve done it this way for decades.
Nope—they’re different cuts. Pork tenderloin is smaller and cooks faster. If yours weighs over 2 pounds, it’s probably a pork loin, not a tenderloin.

Grilled pork tenderloin recipe reads great. My only question is about the grill itself. Do you ever give alternate instructions for using a grill such as the George Foreman or any other indoor covered grill? Being alone, that is what I use and never can find alternates. Love your recipe site and the 'chubby' puppies at the end of each e-mail. They must like your cooking too.

Hi Sharon,
Welcome to the blog.
Cooking in a Foreman type grill gets a little tough with thicker meat like a pork tenderloin. You are probable better served with a pan sear and then oven baked to final temp. https://www.101cookingfortwo.com/pan-seared-oven-roasted-pork-tenderloin/ or cutting across grain to make pork medalions like https://www.101cookingfortwo.com/easy-grilled-pork-tenderloin-medallions/. Thinner recipes like my grilled chicken breast sandwiches or pork tenderloin sandwiches will also work.
Hope that helps.
Dan

Can this be made in the oven? If so, what temp & time?
Dan Mikesell AKA DrDan says
Hi Jan,
This is more of a grilling technique method. For oven baking, the most popular recipe is https://www.101cookingfortwo.com/pan-seared-oven-roasted-pork-tenderloin/ which uses the brief sear then baking. Or as a sheet pan meal with veggies https://www.101cookingfortwo.com/one-pan-roasted-pork-tenderloin-with-potatoes-and-carrots/
