Pork tenderloin is a wonderfully lean and flavorful cut of meat, but its leanness can be a double-edged sword. While it’s a healthier choice compared to fattier cuts of pork, it also means it’s prone to drying out if not cooked properly, especially on the grill. Grilling pork tenderloin to juicy perfection requires attention to detail, a bit of technique, and understanding the factors that contribute to moisture loss. This guide will walk you through everything you need to know to consistently grill succulent pork tenderloin every time.
Choosing the Right Pork Tenderloin and Preparation
The journey to a juicy grilled pork tenderloin begins long before you even light the grill. Selecting the right cut and preparing it correctly are essential steps.
Selecting Quality Pork Tenderloin
Look for pork tenderloins that are pink in color and firm to the touch. Avoid any that appear pale or have a slimy texture. The packaging should be airtight and the “sell by” or “use by” date should be well in the future. Pay attention to the size as well. Pork tenderloins typically weigh between 1 and 1.5 pounds. Smaller tenderloins might overcook more easily. Opt for tenderloins that have a consistent thickness to ensure even cooking.
Trimming and Preparing the Tenderloin
Pork tenderloins often have a silver skin, a thin, silvery membrane, running along one side. This silver skin is tough and doesn’t break down during cooking, so it’s best to remove it. Use a sharp knife to carefully slide under the silver skin and trim it away. Be careful not to remove too much of the underlying meat.
After trimming, pat the tenderloin dry with paper towels. This helps the surface brown nicely on the grill.
The Importance of Marinades and Brines
Marinades and brines are your best friends when it comes to keeping pork tenderloin moist on the grill. They add flavor and help the meat retain moisture during cooking.
Marinades: Marinades typically contain an acid (like lemon juice or vinegar), oil, and seasonings. The acid helps to break down the muscle fibers, tenderizing the meat. The oil helps to prevent the meat from drying out, and the seasonings add flavor. Marinate the pork tenderloin for at least 30 minutes, but preferably for several hours or even overnight in the refrigerator.
Brines: Brines are salt-water solutions that penetrate the meat, hydrating the muscle fibers and adding flavor. Brining is particularly effective for lean cuts like pork tenderloin. A simple brine can consist of water, salt, and sugar. You can also add herbs, spices, and other flavorings to the brine. Brine the pork tenderloin for 2-4 hours in the refrigerator. Be sure to rinse the brine off before grilling.
Dry Rubs: Flavor without Added Moisture
While marinades and brines add moisture, dry rubs focus solely on flavor. Apply a dry rub to the pork tenderloin just before grilling. The rub will create a flavorful crust on the outside of the meat. Common ingredients in dry rubs include salt, pepper, paprika, garlic powder, onion powder, and herbs.
Mastering the Grilling Process
The grilling process itself is crucial to preventing dry pork tenderloin. Temperature control, cooking time, and proper technique are all essential.
Grill Preparation: Setting Up for Success
Whether you’re using a gas grill or a charcoal grill, proper preparation is key. Clean the grill grates thoroughly to prevent sticking. Preheat the grill to medium-high heat (around 350-400°F). This temperature allows for a good sear on the outside while cooking the inside evenly.
Two-Zone Grilling: Consider setting up a two-zone grilling system. This means having one side of the grill with direct heat and the other side with indirect heat. This allows you to sear the pork tenderloin over direct heat and then move it to indirect heat to finish cooking without burning.
Searing for Flavor and Moisture Retention
Searing the pork tenderloin is an important step in locking in juices and creating a flavorful crust. Place the tenderloin on the hot grill grates and sear for 2-3 minutes per side, until nicely browned.
Indirect Heat Cooking: The Key to Even Cooking
After searing, move the pork tenderloin to the indirect heat side of the grill. This allows the meat to cook through evenly without drying out. Close the grill lid and maintain a consistent temperature.
The Importance of a Meat Thermometer
The most accurate way to determine if pork tenderloin is cooked is to use a meat thermometer. Insert the thermometer into the thickest part of the tenderloin, being careful not to touch any bone. The internal temperature should reach 145°F (63°C). This is the USDA’s recommended safe minimum internal temperature for pork.
Avoiding Overcooking: Overcooking is the primary reason for dry pork tenderloin. Use a meat thermometer and remove the tenderloin from the grill as soon as it reaches 145°F.
Resting the Pork Tenderloin: Letting the Juices Redistribute
Once the pork tenderloin is cooked, remove it from the grill and let it rest for at least 5-10 minutes before slicing. Tent it loosely with foil to keep it warm. Resting allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product.
Tips and Tricks for Extra Juicy Pork Tenderloin
Beyond the basic techniques, there are a few extra tips and tricks that can help you achieve consistently juicy grilled pork tenderloin.
Basting During Grilling
Basting the pork tenderloin with a flavorful sauce during grilling can help to keep it moist and add extra flavor. Use a basting brush to apply the sauce every 5-10 minutes during the indirect heat cooking process. Choose a sauce that complements the flavors of your marinade or rub. Be mindful of sauces with high sugar content, as they can burn easily.
Wrapping in Bacon or Larding
Wrapping the pork tenderloin in bacon is a surefire way to add flavor and moisture. The bacon fat will render during grilling, basting the pork and keeping it juicy. Secure the bacon with toothpicks.
Larding is a similar technique that involves inserting strips of fat (like bacon or salt pork) into the pork tenderloin before grilling. This helps to keep the meat moist from the inside out.
Adding a Water Pan to the Grill
If you’re using a charcoal grill, adding a water pan to the grill can help to create a more humid environment, which can prevent the pork tenderloin from drying out. Place a pan of water on the cool side of the grill. The water will evaporate during cooking, adding moisture to the air.
Controlling Flare-Ups on the Grill
Flare-ups can cause the pork tenderloin to burn and dry out. To prevent flare-ups, trim excess fat from the tenderloin before grilling. Keep a spray bottle of water handy to extinguish any flare-ups that do occur. Avoid overcrowding the grill, as this can restrict airflow and increase the risk of flare-ups.
The Importance of Accurate Temperature Monitoring
Beyond using a meat thermometer for the internal temperature of the pork, monitoring the grill temperature is also critical. Use a grill thermometer to ensure that you’re maintaining the correct temperature throughout the cooking process. Adjust the vents on your grill to control the temperature.
Troubleshooting Common Issues
Even with careful planning and execution, things can sometimes go wrong. Here are some solutions to common issues.
Dry Pork Tenderloin
If your pork tenderloin is consistently dry, review your technique. Are you marinating or brining? Are you searing the meat properly? Are you using a meat thermometer and removing the pork at 145°F? Are you resting the meat before slicing? Make sure you’re addressing all of these factors.
Burnt Pork Tenderloin
Burnt pork tenderloin is usually caused by cooking at too high of a temperature or leaving the meat on the direct heat for too long. Make sure you’re using a two-zone grilling system and cooking the pork over indirect heat for most of the cooking time. Watch for flare-ups and extinguish them promptly.
Unevenly Cooked Pork Tenderloin
Unevenly cooked pork tenderloin can be caused by inconsistent thickness or uneven heat distribution on the grill. Try to select tenderloins that are of uniform thickness. Rotate the tenderloin on the grill periodically to ensure even cooking.

What is the ideal internal temperature for a perfectly grilled pork tenderloin?
The ideal internal temperature for a perfectly grilled pork tenderloin is 145°F (63°C). This temperature ensures the pork is cooked to a safe level while remaining juicy and tender. Using a reliable meat thermometer is crucial to achieving this level of doneness and avoiding overcooking, which leads to dryness.
Once the tenderloin reaches 145°F, remove it from the grill and let it rest for at least 5-10 minutes before slicing. During this resting period, the internal temperature will continue to rise slightly, and the juices will redistribute throughout the meat, resulting in a more flavorful and moist final product. Aim for a final temperature of around 150°F after resting.
How long should I marinate pork tenderloin before grilling?
Marinating pork tenderloin for at least 30 minutes is recommended to enhance its flavor and moisture content. A longer marinating time, up to 4 hours in the refrigerator, will allow the flavors to penetrate deeper into the meat, resulting in a more intense and delicious taste. Avoid marinating for longer than 4 hours, as the acidity in some marinades can cause the pork to become mushy.
When preparing your marinade, consider using ingredients like olive oil, lemon juice or vinegar, herbs, and spices. A good marinade helps to tenderize the pork and infuse it with the desired flavors. Ensure the tenderloin is fully submerged in the marinade for consistent flavor absorption. After marinating, pat the tenderloin dry before grilling to promote better searing.
What is the best grilling method for preventing pork tenderloin from drying out?
The best grilling method to prevent pork tenderloin from drying out is to use a combination of searing and indirect heat. Start by searing the tenderloin over medium-high heat for about 2-3 minutes per side to create a flavorful crust and lock in the juices. This initial searing step is crucial for developing that desirable grilled flavor and texture.
After searing, move the tenderloin to a cooler part of the grill or reduce the heat to medium-low. Continue cooking using indirect heat until it reaches an internal temperature of 145°F (63°C). This gentle cooking process allows the pork to cook evenly without drying out. Avoid overcooking, as it is the primary cause of dry pork tenderloin.
Should I brine pork tenderloin before grilling?
Yes, brining pork tenderloin before grilling is an excellent way to ensure it remains moist and flavorful. Brining involves submerging the pork in a saltwater solution, which helps the meat retain moisture during the cooking process. This is particularly beneficial for lean cuts like tenderloin that are prone to drying out.
A typical brine consists of salt, sugar, and water, but you can also add herbs, spices, and aromatics to enhance the flavor. Soak the pork tenderloin in the brine for at least 30 minutes and up to 2 hours in the refrigerator. After brining, rinse the pork thoroughly with cold water and pat it dry before grilling.
What are some tips for keeping pork tenderloin moist while grilling?
Several techniques can help keep pork tenderloin moist while grilling. Regularly basting the pork with a flavorful sauce or marinade during the grilling process can add moisture and flavor. Use a silicone brush to apply the sauce evenly, especially during the last few minutes of cooking. Be careful to avoid flare-ups from sugary sauces.
Another tip is to avoid overcrowding the grill. This allows for better heat circulation and more even cooking. Also, resist the temptation to constantly flip the tenderloin. Limiting the number of flips helps to retain moisture. Most importantly, use a meat thermometer to monitor the internal temperature and avoid overcooking.
What is the proper way to slice pork tenderloin after grilling?
The proper way to slice pork tenderloin after grilling is to let it rest for 5-10 minutes, then slice it against the grain. Resting allows the juices to redistribute, resulting in a more tender and flavorful bite. Slicing against the grain, which means cutting perpendicular to the muscle fibers, shortens the fibers and makes the meat easier to chew.
Use a sharp knife to slice the tenderloin into thin, even medallions. Cutting at a slight angle can further enhance the presentation. Arranging the slices on a platter with any accumulated juices adds visual appeal and enhances the overall dining experience. Serving immediately after slicing ensures the pork is enjoyed at its best.
Can I use a gas grill or charcoal grill for pork tenderloin?
Yes, you can use either a gas grill or a charcoal grill for cooking pork tenderloin. Gas grills provide consistent and easily controllable heat, making it simpler to maintain the desired temperature for searing and indirect cooking. Charcoal grills offer a smoky flavor that many people enjoy, but require more attention to temperature management.
When using a gas grill, preheat it to medium-high heat for searing, then reduce the heat for indirect cooking. For a charcoal grill, create a two-zone fire with one side hotter than the other. Sear the pork tenderloin over the hot coals and then move it to the cooler side to finish cooking. Both methods can produce delicious results with proper attention to technique.
