This super easy tutorial teaches the secrets to juicy and tender grilled pork tenderloin. A properly grilled pork tenderloin will make you look like the grill master. Just don't tell them how simple it is.
Introduction
We all know that pork is "the other white meat." What a great marketing phrase. And it has a little truth in it since it is a lean cut of meat but still more fat than chicken breast meat. It is perfect for a keto diet and fits nicely into most lower-fat diets.
Pork tenderloin may be the perfect meat for grilling. It can be elegant or casual to fit almost any occasion. It’s cheap and healthy, plus its smaller size makes it near perfect for smaller households. But easy to double up for larger needs.
So let's learn how to cook pork tenderloin to perfection on your grill—the best way to cook any pork.
👨🍳How to make this recipe
- Clean, oil, and preheat the grill to a surface temperature of about 450°.
- Trim the tenderloin—most will have a "silver skin" that should be removed. It is some tough connective tissue. Brine if you wish.
- Season to your taste. Just salt and pepper are enough but use any seasoning you wish. I suggest All Purpose Seasoning - 7:2:1 and 7:2:2.
- Grill over direct heat with the hood closed. Rotate the pork tenderloin ⅓ every 4-5 minutes. It is 3-sided meat.
- Grill until an internal temperature of a minimum of 145°—about 25 minutes but will vary by weight and thickness.
- Remove from grill and tent with foil for 5-10 minutes before serving.
⏰How Long to Grill
The recommended medium rare internal temp of 145° will take about 25 minutes. Approximate times are for a 1 ½ pound pork tenderloin and a 450° grill surface temperature. Times are provided to help with planning but never cook by time; always cook to a final internal temperature. The meat will rise 2° to 4° after removal from the grill.
| Cooked Pork Level | Internal Temperature | Approx. Grilling time |
|---|---|---|
| Rare | Not recommended | Not recommended |
| Medium-Rare | 145°-150° | 22-27 minutes |
| Medium | 150°-155° | 27-30 minutes |
| Medium-Well | 155°-160° | 29+ minutes |
| Well Done | 160°+ | Not recommended |
🐖About Pork Tenderloin
The tenderloin refers to the psoas muscle along the lower back. It is chicken tenders in the chicken or beef tenderloin (filet mignon) in cattle. The psoas is generally the most tender cut since they are not used for movement.
The big secret about pork tenderloin is that it is not round, flat, or even square. It is a triangle, so there are three sides. So, whether cooking on a grill or in a pan, cook three sides and don't force it into a shape that is not naturally.
A pork loin is NOT a pork tenderloin. They are different cuts of meat and do not cook the same.
If you are not sure, just the size will tell you. The tenderloin usually weighs about 1 to 1 ½ pounds. A huge one could push towards 2 pounds. If you think you have a four-pound tenderloin, you are mistaken.
Should I brine pork tenderloin?
Brine is not needed but will add more moisture and tenderness. But realize it is already very tender and moist. If you do brine, do not season with additional salt.
To brine, a good starting point is to add 1 tablespoon of salt and seal it in a food storage bag for every cup of water.
You can fancy up your brine, some with sugar or brown sugar. Use about the same amount of sugar as salt. You can add some garlic or other things for flavor. An hour or two is enough time.
Of course, refrigerate during the brining and rinse the tenderloin with running water, and pat dry at the end.
FAQs
.Work a finger or butter knife under it and work it off. A sharp knife may be needed if a few spots, and the back of the knife blade may be used instead of the butter knife.
The pork is done at a minimum of 145° internal temperature in the thickest part. According to the USDA, that is the minimum safe internal temperature with a 3-minute rest after cooking.
You must check the temperature with an instant-read thermometer or meat thermometer.
Side dishes are always hard to choose. I suggest vegetables like Grilled Mixed Vegetables or Grilled Asparagus make an excellent side dish. We like to have potatoes of some type like Grilled Baby Potatoes. And fresh salad goes with everything.
Brown Sugar Cinnamon Glazed Grilled Pineapple is a great dessert served with ice cream.
Leftovers can be refrigerated in an airtight container for up to 4 days and reheated in a microwave. I live to slice up cold leftovers on a green salad.

Trim the tenderloin of any excess fat and the silver skin.
Optional Brine: Start with 4 cups of water with 4 tablespoons salt in a food-storage plastic bag. Add 2-4 tablespoons of sugar if you want. Refrigerate for 1-2 hours. When done with the brine, remove it from the brine, rinse under running water, and pat dry. Salt and black pepper or other seasonings at this point, but DO NOT ADD SALT if you brine.
Preheat the grill to a surface temperature of 450° to 500°—medium-high on most grills. Clean and oil grates well.
Place over direct heat—close the lid. Rotate ⅓ every 5 minutes until done to your liking. About 25 minutes for 145°, but do not cook by time alone—use a thermometer. The time to get to your final temperature varies by weight and the exact surface temperature of the grill.
Remove from the grill a few degrees less than your desired final temperature. Tent lightly for 5 minutes before serving.

Pro Tips
- Remember it is triangular meat not round. So a flip is ⅓ of a rotation.
- Brine if you have time but results are still excellent without a brine.
- Cook over medium to medium-high heat. Use a grill surface thermometer to get 450° to 500°.
- Season any way you want but do not add more salt if you brined.
- The final internal temperature of 145°-150° is nicely done.

Perfect! No brining or marinating. Just rubbed on olive oil garlic and rosemary. Served with homemade rhubarb chutney. Tis the season. OMG yum.
Jonny
I made this and it was fantastic. It was an easy but delicious Mother’s Day lunch made wen we got home from church. I did the brine while we were out and then seasoned with black pepper and crushed rosemary. I also used Hickory wood chips in a smoke box for added smoke flavor.
Roasted Brussel sprouts in a foil pack as a side.
Thanks Dr. Dan!
Don
Do you cook the Pork Tenderloin over Direct heat and the Indirect? Or over Direct heat the entire time at 450 ish?
Thanks
Dan Mikesell AKA DrDan
Hi Don,
Welcome to the blog.
Direct heat entirely in the 450°range. The grill surface temperature is the most important part in getting the correct internal temperature with nice color on the outside without burning.
You could sear than go indirect but that complicates the process needlessly.
Dan
chris
have used the recipe twice, both turned out great, thanks!
Peter
I make it based on time. Tenderloins don’t vary that much in size. Employ direct and indirect methods. Works with gas or charcoal(full chimney). Place over direct high heat. Rotating until a slight char all the way around. Move to the indirect side, close the lid and wait 18 minutes. Remove and rest for 5. Beautiful medium-well.
Lew Lowther
I tried your conversion to metric option. It converted cups-to-ml, but did nothing with pounds or tablespoons in the recipe, nor did it make any changes whatsoever in the Instructions, most notably temperature! Dunno if the recipe is any good. The half-baked attempt at making it accessible was enough to put me off.

Just made on weber 1200 gas grill. I have never had better or more tender. i marinated overnight did not brine. (Used soy sauce, garlic, maple syrup, horse radish, olive oil) The PL we bought was cut in half length wise. I did 3 min. on larger sides (I was afraid 5 min would be too long), then propped them up against a rolled up piece of foil to do 2+ min on thin sides. placed foil under tapered end once it reached 130 degrees while larger end continued to come up to 130. Then tented off grill 5min. to rest. 140 degrees was perfect.

Great recipe easy to follow directions Taste fantastic

You said:
"For me, I use a super-duper Weber that can get very hot, and that will be a small amount over 50%."
50% of what?
Dan Mikesell AKA DrDan
Hi Lenny,
Welcome to the blog.
50% means only halfway on the knob. So 50% power to the burner.
Hope that helps. Please ask if you have other questions.

I make a cream sauce out of creamed corned to place on the bottom of the plate, then place grilled pork medallion on top. Sides of fresh colorful vegetables, bean, red pepper, yellow squash, zucchini, carrots, taters, onions, etc.
Janet Mince
Excellent instructions and easy to follow! Used a pre-seasoned pork loin but wrapped in bacon just because I can. Lol. Turned out great and didn't overcook.
Ron
Dr. Dan
I used the thin copper grill mate on top of the grates to keep from getting direct flames. Grilled it until the tenderloin reached 145 and let it rest 10 minutes. Turned out awesome. You did a great job explaining all of the needed details. 👍 5
Todd
Can I wrap it in aluminum foil and grill it
DrDan
No, I would not with this recipe/instructions. You probably should look around for somebody that uses foil that way. I have not, so can't really discuss it. But this works great without foil.
Dan
Marc Guerin
I’m adding garlic salt and smoked paprika to my brine. Hopefully it will taste good when I cook it
Katie Perry
Dr. Dan, I hope you can advise me in regard to converting a pan-sear-then-roast pork tenderloin recipe to the grill. Ina Garten has a lovely "Herb Marinated Pork Tenderloin" recipe on Food Network's site that I'm crazy about. In Arizona, turning the oven on in the summer is really bad for your electric bill. Can you foresee any particular deviations to your instruction given that I have two tenderloins (approximately 1.1 lbs) and they will be marinated in a lemon/olive oil/fresh garlic + herb mixture? I like my tenderloin on the pinker side, so the grilling aspect makes me nervous. I would appreciate any wisdom in this regard as I want to make it for my special someone as a welcome home.
DrDan
Hi Katie,
I see two choices for the grill.
First her recipe up to but not including the searing. At that point, my instructions after a brush of oil on the tenderloin. You need to keep the surface temperature 400-450. It should take about 20-25 minutes.
Option #2. Is to use a large grill pan or cast iron skillet. Preheat it on the grill and then sear and finish in the pan.
Both options require you know the surface temperature of the grill accurately. The biggest mistake people make is not knowing their grill temp. So a $10 grill surface thermometer from Home Depot or Amazon should be fine. I use a $200 plus one from Thermoworks. Also, a instant read meat thermometer.
Personally, I would do #1.
Also for important meals, I never, never, never use a new technique. A trial run is indicated here. You have variables of the grill surface temp, the movement of air in the grill, the wt and thickness of the tenderloin. Yep, a trial run first.
Hope that helps
Dan

I LOVE your commentary about Pork Tenderloin / Chicken Tenders & Filet Mignon!! Great info I've never heard anyone explain so clearly!!!
DrDan
Hi Janice,
I think I played too much "name that muscle" 40 yrs ago in med school. But some muscles like the psoas are more for positioning then strength or movement. The more the muscle is used, the tougher it becomes. I couldn't find a good diagram that I could legally use so I used one I had and drew in the tenderloin.
Thanks for the comment. I just finished cooking this again tonight and my wife gave another 5.
