Choosing The Right Pork Tenderloin
Cooking pork tenderloin on a charcoal grill starts with picking the right meat. Good quality pork ensures a juicy and tasty meal.
Understanding how to select and prepare the pork makes grilling easier and more enjoyable.

| Trimming Step | Description |
|---|---|
| Remove Silver Skin | Use a sharp knife to cut away the thin, white membrane |

Setting Up The Charcoal Grill
Cooking pork tenderloin on a charcoal grill needs careful setup. Proper heat and airflow give the best results.
This guide explains how to light the charcoal and create heat zones for even cooking.
Lighting The Charcoal
Start by arranging charcoal in a pile or chimney starter. Light the charcoal safely with matches or a lighter.
Wait until the charcoal is covered with white ash before cooking. This usually takes 15 to 20 minutes.
- Use a chimney starter for easy lighting
- Light charcoal outdoors in a safe area
- Let charcoal burn until it is ashy gray
Creating Heat Zones
Arrange the charcoal to make two heat zones: one hot for searing and one cooler for cooking.
Place more charcoal on one side for direct heat. Leave the other side with fewer coals for indirect heat.
- Hot zone: many coals for searing pork
- Cool zone: fewer coals for slow cooking
- Use grill lid to control temperature
Ideal Temperature For Grilling
Grilling pork tenderloin on a charcoal grill can be delicious. It’s important to cook it at the right temperature.
The temperature ensures the meat is juicy and safe to eat. Let’s explore how to achieve the perfect grill.
Target Grill Temperature
To cook pork tenderloin, keep the grill at medium heat. This means about 350°F to 375°F.
Maintaining this temperature helps the pork cook evenly. It prevents the outside from burning while the inside stays raw.
- Use a thermometer to check the grill’s temperature
- Adjust vents to control the heat
- Add charcoal if the temperature drops
Using A Meat Thermometer
A meat thermometer is helpful when grilling pork. It ensures the meat reaches a safe internal temperature.
Insert the thermometer into the thickest part of the tenderloin. The pork is ready when it reaches 145°F.
- Check the temperature near the end of cooking
- Let the meat rest for 3 minutes after grilling
- Resting helps the juices redistribute
Timing The Cooking Process
Cooking pork tenderloin on a charcoal grill needs attention to time and heat. Proper timing ensures the meat is juicy and safe to eat.
Knowing how long to grill helps avoid undercooking or drying out the pork. Let’s look at the average cook time and how to adjust for size.
Average Cook Time
On a charcoal grill, pork tenderloin usually takes about 20 to 30 minutes to cook. The grill should be medium heat, around 350°F (175°C).
- Preheat the grill to medium heat before placing the meat.
- Cook the tenderloin for 4 to 5 minutes on each side to get a good sear.
- Move the tenderloin to indirect heat to finish cooking.
- Use a meat thermometer to check for an internal temperature of 145°F (63°C).
Adjusting For Tenderloin Size
The size of your pork tenderloin affects cooking time. Thicker pieces need longer on the grill. Thinner ones cook faster.
| Weight of Tenderloin | Approximate Cook Time |
| Under 1 pound (450g) | 15 to 20 minutes |
| 1 to 1.5 pounds (450-680g) | 20 to 25 minutes |
| Over 1.5 pounds (680g+) | 25 to 30 minutes |
Grilling Techniques For Juicy Meat
Cooking pork tenderloin on a charcoal grill takes some skill. You want the meat juicy and tender, not dry.
Using the right grilling techniques helps keep the pork moist and full of flavor. Control the heat and handle the meat carefully.
Direct Vs Indirect Heat
Direct heat means placing the pork right over the coals. This cooks the outside fast and adds grill marks.
Indirect heat cooks the pork slower. You place the meat away from the coals and close the lid. This helps the inside cook evenly.
- Start by searing on direct heat for 2-3 minutes per side.
- Move the pork to indirect heat to finish cooking.
- Keep the grill covered to keep heat steady.
- Use a meat thermometer to check for 145°F inside.
Turning And Basting Tips
Turn the pork tenderloin every 4-5 minutes. This helps it cook evenly and avoid burning.
Basting adds moisture and flavor. Use a brush to spread marinade or sauce while grilling. Avoid too much basting to keep the fire steady.
- Turn the meat gently to keep juices inside.
- Baste 2-3 times during cooking, especially after searing.
- Use a heat-safe brush for basting.
- Let the pork rest 5 minutes after grilling before cutting.
Checking Doneness Safely
Cooking pork tenderloin on a charcoal grill needs care to ensure it is safe. Checking doneness is important to avoid undercooked meat.
Using the right tools and methods helps you cook the pork just right. This keeps the meat juicy and safe to eat.
Internal Temperature Guidelines
Use a meat thermometer to check the pork’s internal temperature. This is the safest way to know if it is done.
Insert the thermometer into the thickest part of the tenderloin. Avoid touching bone or fat for accurate reading.
- Cook pork to an internal temperature of 145°F (63°C).
- This temperature ensures the pork is safe but still juicy.
- If you prefer well-done pork, cook to 160°F (71°C).
- Rest the meat after cooking to allow the temperature to even out.
Resting The Meat
Rest the pork tenderloin for 5 to 10 minutes after grilling. This helps the juices spread inside the meat.
Resting makes the pork tender and flavorful. Do not cut the meat right after cooking.
- Remove pork from the grill once it reaches the right temperature.
- Cover loosely with foil to keep warm while resting.
- Let it rest on a cutting board or plate before slicing.
