Grilled Pork Tenderloin (Juicy, Easy Recipe)

14 If you want a summer main that feels a little special but barely asks anything of you, this grilled pork tenderloin is the one I keep coming back to. A smoky spice rub, a quick sear over the flames, then a gentle finish until the inside is blushing pink and unbelievably juicy. Pork tenderloin was made for the grill. It is lean, it cooks in under twenty minutes, and it slices into pretty little medallions that look like you fussed far more than you actually did. The whole thing comes together with a rub of pantry spices and a two-zone fire, so you sear on the hot side, slide it over to the cooler side to finish, and let it rest while you pour the drinks. Serve it with something summery, and you have a dinner that works just as well on a busy Tuesday as it does when friends are crowded around the patio table.

Why You’ll Love This Grilled Pork Tenderloin

Some grilling projects eat up your whole afternoon. This one, happily, does not. Here is why this easy grilled pork tenderloin has earned a regular spot in our summer rotation.

• It is fast. Start to finish you are looking at about half an hour, and most of that is hands off while the grill does the work.
• The spice rub is all pantry staples. Smoked paprika, garlic powder, onion powder, a little brown sugar, and a pinch of chilli. Nothing you need to hunt down.
• It stays juicy. Searing first and finishing over indirect heat keeps the lean meat tender instead of dry, which is the whole battle with pork tenderloin.
• It feeds a crowd or a weeknight. One tenderloin serves three or four, and it is easy to throw two or three on the grill when you need more.
• Leftovers are gold. Cold slices are wonderful in wraps, grain bowls, and salads the next day.

Ingredient Notes

This is a short list, so every piece pulls its weight. Here is what I would keep in mind before you fire up the grill.

• Pork tenderloin. You want one tenderloin, roughly 450 to 550 g, which is about a pound. Look for a piece that is evenly thick so it cooks at the same rate, and trim off any silverskin, that thin silvery membrane, so it does not turn chewy.
• Olive oil. Just a tablespoon, rubbed all over. It helps the rub cling and encourages that deep, browned crust when the pork hits the hot grates.
• Smoked paprika. This is the backbone of the flavour, adding a gentle smokiness that makes the pork taste like it spent hours over coals.
• Brown sugar. Just half a tablespoon. It rounds out the spices and helps the exterior caramelize, without making things sweet.
• Garlic powder, onion powder, thyme, and chilli powder. The savoury, herby, lightly spicy layer. Feel free to lean into the chilli if your table likes heat.
• BBQ sauce. Totally optional, brushed on at the very end for a sticky glaze. For food safety and cooking basics, the USDA has a helpful guide to fresh pork worth a quick read.

Pork Tenderloin vs Pork Loin (They Are Not the Same)

This trips people up all the time, so it is worth thirty seconds. A pork tenderloin is small, long, and thin, usually around a pound, and it is the most tender cut on the pig. A pork loin is a much larger, wider roast that can weigh several pounds and takes far longer to cook. They are not interchangeable, and grilling a big pork loin the way you grill a tenderloin will leave you with a raw center. Everything below is written for the quick cooking tenderloin. If you are working with a larger pork loin, you will still sear then finish over indirect heat, but you should plan on a much longer cook and lean on a thermometer even more. The National Pork Board breaks down the different cuts if you want to see exactly what you bought.

How to Grill Pork Tenderloin

The method is really just three moves: rub it, sear it, then finish it gently. Here is how it goes, and you will find the full measurements in the recipe card at the bottom of this post. 1. Season the pork. First, pat the tenderloin dry with kitchen roll, which is the secret to a good crust. Rub it all over with the olive oil, then mix your spices together and coat the pork evenly on every side. 2. Sear over direct heat. Next, set up a two zone fire with one hot side and one cooler side. Lay the tenderloin over the hot zone and sear for about two minutes per side, turning until the whole surface is nicely coloured. This is where all that flavour is built. 3. Finish over indirect heat. After that, move the pork to the cool zone and close the lid. Let it cook for twelve to eighteen minutes, turning once halfway, until it reaches temperature. If you like a glaze, brush on a little BBQ sauce for the last two or three minutes so it sets without burning. Finally, and please do not skip this, rest the pork for five minutes before slicing. The juices redistribute as it sits, so you get moist medallions instead of a puddle on the board.

How Long to Grill Pork Tenderloin

Start to finish, a one pound tenderloin takes roughly fifteen to twenty two minutes on the grill, plus a five minute rest. That breaks down to about two minutes per side over direct heat for the sear, then another twelve to eighteen minutes over indirect heat to cook through. Timing shifts a little depending on your setup, so use these as a guide:

• Gas grill. Sear over high heat, then finish over a burner turned to medium low with the lid down. Expect the full cook to land around fifteen to twenty minutes.
• Charcoal grill. Bank the coals to one side for your two zones. The cook time is similar, though a hot bed of coals can move things along faster, so check a couple of minutes early.
• Thickness matters more than weight. A fat, evenly shaped tenderloin takes longer than a thin, tapered one, so lean on temperature rather than the clock.

Honestly, the single best thing you can do is use an instant read thermometer. Grills run hot and cool in different spots, and pork tenderloin goes from perfect to overdone in just a minute or two.

What Temperature for Grilled Pork Tenderloin

Pull the pork off the grill when the thickest part reads 145 degrees F, which is 63 degrees C, then let it rest for five minutes. That is the sweet spot for juicy, slightly pink pork that is completely safe to eat. The USDA lowered its recommended pork temperature to 145 degrees F years ago, so there is no need to cook it grey and dry the way older recipes told us to. A little carryover cooking happens while it rests, so the temperature climbs a few more degrees off the heat. If pink pork makes anyone at your table nervous, take it to 150 degrees F, but I would not go higher than that, or you start losing the juiciness. If you love dialing in doneness, our guide to the best temperature to grill steak uses the same thermometer logic.

Tips for the Juiciest Grilled Pork Tenderloin

A few things I have picked up after grilling more of these than I can count.

• Remove the silverskin. That thin silvery membrane never softens and can make the pork curl as it cooks. Slide a knife under it and trim it away first.
• Do not skip the sear. The hot zone gives you colour and a savoury crust that the gentle finish alone cannot.
• Cook to temperature, not time. This is the whole ballgame with lean pork. A thermometer takes the guesswork out completely.
• Always rest before slicing. Five minutes lets the juices settle so they stay in the meat instead of running out.
• Slice against the grain. Cutting across the muscle fibers into medallions keeps every bite tender.

Storage Options

Grilled pork tenderloin keeps beautifully, which is half the reason I love making it.

• Refrigerator. Store cooled slices in an airtight container for three to four days.
• Freezer. Freeze cooked pork for up to two months. Thaw it overnight in the fridge before reheating.
• Reheat gently. Warm slices in a low oven or a covered pan with a splash of broth so they do not dry out. A quick blast in the microwave works too, just keep it brief.
• Serve it cold. Honestly, leftover medallions are fantastic straight from the fridge, piled onto a salad or into a sandwich.

Variations and Substitutions

This recipe is an easy one to make your own, so here are a few ways I like to switch it up.

• BBQ glazed. Brush on your favourite barbecue sauce in the last few minutes, then serve with extra on the side. If you are already in a low and slow mood, our oven baked baby back ribs make a great companion cook.
• Herb and garlic. Swap the smoked paprika rub for fresh rosemary, thyme, and minced garlic mashed with the olive oil.
• Sweet and spicy. Add a spoonful of honey and a bigger pinch of chilli for a sticky, warming glaze.
• Marinated. Let the tenderloin sit in a simple soy, garlic, and brown sugar marinade for a few hours before grilling for a deeper flavour.
• On chicken. This exact spice rub is wonderful on chicken breasts or thighs, so keep it in your back pocket.

What to Serve With Grilled Pork Tenderloin

Pork tenderloin is friendly with almost any summer side. A few of my favourites, since someone always asks:

• A big scoop of creamy macaroni salad, which is practically the law at a cookout
• Smoky, saucy homemade baked beans for a proper barbecue plate
• Grilled vegetables like courgette, peppers, and corn, thrown on while the pork rests
• Fluffy rice or buttery mashed potatoes when you want something a bit heartier
• A crisp green salad if you are keeping things light

And because the grill is already hot, it is worth cooking a little extra of everything so lunch tomorrow sorts itself out.
