๐จโ๐ณQuick Overview: How to Grill a Pork Tenderloin on a Gas Grill
1. Trim and prep
Trim off the silver skin and any excess fat.
2. Optional brine and season
Brine for 1โ2 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 450ยฐโ500ยฐF. Close the lid and rotate โ every 5 minutes. Cook to an internal temp of 145ยฐโabout 25 minutes total.
โ Pro Tip: Pork tenderloin is shaped like a triangle. Flip it one-third of a turn each time to cook all sides evenly.
โ 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 5โ10 minutes so the juices reabsorb. Then slice across the grain and serve.

โฒ๏ธ How Long to Grill Pork Tenderloin on a Gas Grill
Grill a 1ยฝ-pound pork tenderloin over direct heat at a surface temperature of 450ยฐF, and it will take about 25 minutes to reach an internal temperature of 145ยฐF (medium-rare). Smaller tenderloins (1ยผ lb) may cook 5โ8 minutes faster, while larger ones (1ยพ lb) could take 5โ10 minutes longer.
Estimated grill times at 450ยฐF for a 1ยฝ-pound tenderloin:
- Rare (<145ยฐF) โ Not recommended (USDA safety guidelines).
- Medium-Rare (145ยฐโ150ยฐF) โ A little pink. About 22โ27 minutes. My go-to and highly recommended.
- Medium (150ยฐโ155ยฐF) โ Around 27โ30 minutes. My wife's choice.
- Medium-Well (155ยฐโ160ยฐF) โ Takes roughly 29โ32 minutes. Fine, if youโre sure.
- Well Done (160ยฐF+) โ Not recommendedโtends to be dry and tough.
Reminder: These times are just a planning guideโalways cook to an internal temperature, not by the clock. The temperature will rise 2ยฐ to 4ยฐF after removing it from the grill.
โ Pro Tip: According to the USDA, pork is safe to eat at 145ยฐFโeven if it's a little pink inside. Thatโs medium-rare and perfectly fine, as long as itโs been rested for 3 minutes.

๐ฅฃSeasoning/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 Seasoningโreally, any seasoning blend you like will work.
For something special, try a marinade like my Balsamic Pork Tenderloin or Alton Browns 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 Tenderloinโa favorite for a reason.
๐ค Troubleshooting and getting it right every time
Most problems come down to two things:ย grill surface temperatureย andย not using an instant-read thermometer.
- Aย grill surface thermometerย tells you the actual temperature where the pork is cooking, not just what the hood says.
- Anย instant-read thermometerย checks doneness by measuring the internal temperature of the meat.
Together, they take the guesswork out of grilling.
While I recommend a gas grill for better control, charcoal works tooโas long as you can manage consistent heat. For more tips on grill temps, see my Guide to Grill Temperature on a Gas Grill.
Hereโs how to fix the most common issues:
- Excessive char โ Flip more often and lower the grill temperature a bit.
- Flare-ups โ Avoid flare zones and trim visible fat before grilling.
- Undercooked center โ Lower the grill temp for gentler, more even cooking.
- Dry pork โ Two main causes:
- Overcooking โ Always cook to 145ยฐF and check with a thermometer.
- Freezer damage โ Pork that's been frozen too long can lose moisture. A quick brine helps, but starting with fresh meat is best.
๐ฝ๏ธServing grilled pork tenderloin
Let the meat rest off the heat for 5 to 10 minutes after grilling so the juices reabsorb. Then slice across the grain for the most tender results.
We usually serve it plain or with a little BBQ sauce, but it also works well with a glaze or light drizzle of pan sauce.
If youโre 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 youโre 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, Macaroni Salad.
- Dessert: Brown Sugar Cinnamon Glazed Grilled Pineapple, Fresh Strawberry Pie.
โ๏ธLeftovers
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.
โFAQs
Yes. According to the USDA, pork is safe to eat at 145ยฐF with a 3-minute restโeven if itโs slightly pink inside. Thatโs medium-rare and perfectly safe when cooked to the right temperature.
Use your finger or a butter knife to slip underneath and loosen it. A sharp knife may be needed for the tougher spots.
Itโs 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. Donโt 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. Iโve done it this way for decades.
Nopeโtheyโre different cuts. Pork tenderloin is smaller and cooks faster. If yours weighs over 2 pounds, itโs 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/
