How Long to Grill Pork Loin on a Gas Grill? Achieving Perfect Doneness
The ideal grilling time for pork loin on a gas grill ranges from *approximately **20 to 25 minutes, depending on the thickness of the loin and your desired internal temperature. Always use a meat thermometer to ensure the pork reaches a safe and delicious *internal temperature of **145°F (63°C).
The Allure of Grilling Pork Loin
Grilling pork loin offers a delightful combination of smoky flavor and lean protein. It’s a versatile cut that can be seasoned in countless ways, from simple salt and pepper to elaborate rubs and marinades. Beyond its taste, grilling pork loin offers several advantages:
- Lean and Healthy: Pork loin is a relatively lean cut of meat, making it a healthier alternative to fattier options.
- Quick and Easy: Grilling provides a fast and efficient cooking method, perfect for busy weeknights.
- Flavorful: The high heat of the grill sears the outside of the pork, creating a beautiful crust and locking in moisture.
- Versatile: Pork loin is a blank canvas for experimentation with different seasonings and flavor profiles.
Preparing Your Pork Loin for Grilling
Proper preparation is crucial for achieving grilling success. Here’s a step-by-step guide:
- Choose Your Pork Loin: Select a pork loin that is evenly thick and has a good amount of marbling (intramuscular fat).
- Trim Excess Fat: Trim off any excess surface fat, leaving a thin layer for flavor and moisture.
- Season Generously: Apply your favorite dry rub or marinade at least 30 minutes before grilling, or preferably overnight. Popular choices include:
- Salt, pepper, garlic powder, onion powder, paprika
- Brown sugar, chili powder, cumin, smoked paprika
- Soy sauce, ginger, garlic, honey
- Bring to Room Temperature: Allow the pork loin to sit at room temperature for about 30 minutes before grilling. This helps it cook more evenly.
Mastering the Gas Grill Technique
Grilling pork loin on a gas grill requires mastering heat control and monitoring internal temperature.
- Preheat Your Grill: Preheat your gas grill to medium-high heat (around 350-400°F or 175-200°C). Aim for indirect heat by only lighting one or two burners.
- Sear (Optional): For a more pronounced crust, sear the pork loin over direct heat for 2-3 minutes per side.
- Grill Over Indirect Heat: Move the pork loin to the unlit side of the grill. Close the lid and grill for 20-25 minutes, or until it reaches an internal temperature of 140°F (60°C).
- Check Internal Temperature: Use a reliable meat thermometer inserted into the thickest part of the loin.
- Rest: Remove the pork loin from the grill and let it rest for 5-10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product. The internal temperature will continue to rise slightly during resting (carryover cooking) and should reach the safe internal temperature of 145°F (63°C).
Common Grilling Mistakes to Avoid
Even experienced grillers can fall victim to common mistakes. Here’s how to avoid them:
- Overcooking: The most common mistake is overcooking the pork loin, resulting in a dry and tough product. Always use a meat thermometer!
- Not Allowing Enough Rest Time: Rushing the slicing process can lead to moisture loss. Be patient and let the pork rest.
- Uneven Heat Distribution: Ensure your grill is properly preheated and that you’re using indirect heat for most of the cooking process.
- Using the Wrong Cut: Ensure you are buying pork loin, not pork tenderloin which is smaller and will cook significantly faster. Pork loin is a larger, wider cut.

Frequently Asked Questions (FAQs)
What is the difference between pork loin and pork tenderloin?
Pork loin and pork tenderloin are two different cuts of pork. Pork loin is a larger, wider cut of meat, while pork tenderloin is a smaller, more tender cut. They require different cooking times and techniques. Pork tenderloin cooks much faster.
Should I marinate my pork loin before grilling?
Marinating pork loin is highly recommended. Marinades add flavor and help tenderize the meat. Allow the pork to marinate for at least 30 minutes, or preferably overnight, in the refrigerator. Acidic marinades, such as those containing citrus juice or vinegar, can help break down the proteins and make the pork more tender.
What temperature should my gas grill be for grilling pork loin?
Your gas grill should be set to medium-high heat, around 350-400°F (175-200°C). Use indirect heat by only lighting one or two burners. This will help prevent the pork from burning on the outside while cooking through.
How do I know when my pork loin is done grilling?
The best way to determine if your pork loin is done is to use a reliable meat thermometer. Insert the thermometer into the thickest part of the loin. The pork is done when it reaches an internal temperature of 145°F (63°C).
Why is my pork loin dry after grilling?
Dry pork loin is often caused by overcooking. Always use a meat thermometer to monitor the internal temperature and avoid cooking past 145°F (63°C). Resting the pork after grilling also helps retain moisture.
Can I use wood chips on a gas grill to add smoky flavor?
Yes, you can use wood chips on a gas grill to add smoky flavor. Soak the wood chips in water for at least 30 minutes before placing them in a smoker box or a foil pouch with holes poked in it. Place the smoker box or foil pouch directly on the lit burner of your grill.
How long should I rest my pork loin after grilling?
Allow your pork loin to rest for 5-10 minutes after grilling. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product.
What are some good side dishes to serve with grilled pork loin?
Grilled pork loin pairs well with a variety of side dishes, including:
- Grilled vegetables (asparagus, zucchini, bell peppers)
- Roasted potatoes
- Rice pilaf
- Salad
- Coleslaw
Can I grill a frozen pork loin?
While not recommended, grilling a frozen pork loin is possible, but it will take significantly longer to cook and may result in uneven cooking. It is always best to thaw the pork loin completely before grilling. Thawing in the refrigerator is the safest method.
How do I prevent my pork loin from sticking to the grill?
To prevent your pork loin from sticking to the grill, make sure the grill grates are clean and well-oiled. You can use cooking spray or brush the grates with oil before placing the pork loin on the grill. Also, avoid moving the pork loin around too much while it’s grilling.
What’s the best way to store leftover grilled pork loin?
Store leftover grilled pork loin in an airtight container in the refrigerator. It will keep for 3-4 days.
Can I reheat grilled pork loin?
Yes, you can reheat grilled pork loin. The best way to reheat it is in the oven at a low temperature (around 250°F or 120°C) with a little bit of broth or water to prevent it from drying out. You can also reheat it in the microwave, but be careful not to overcook it.
