When selecting a pork tenderloin for grilling, several factors should be considered. The ideal cut should be pale pink with visible marbling, as the fat contributes to moisture and tenderness during cooking. Avoid meat with strong odors, which may indicate spoilage.
A uniform size and shape promote even cooking on the grill. It’s advisable to choose pork raised without antibiotics or hormones, preferably from local sources that prioritize animal welfare and sustainable practices. The optimal thickness for grilling is approximately 1 1/2 to 2 inches in diameter, allowing for even and quick cooking.
Thicker cuts may require longer cooking times and risk overcooking the exterior, while thinner cuts can dry out quickly. A pork tenderloin weighing 1 1/2 to 2 pounds is suitable for grilling and typically serves 4 to 6 people. By carefully selecting the right cut, you can ensure a high-quality starting point for a flavorful grilled meal.
Key Takeaways
- Choose pork tenderloin with a pinkish-red color and some marbling for the best flavor and tenderness
- Trim excess fat and silver skin from the pork tenderloin before grilling to prevent flare-ups and ensure even cooking
- Season the pork tenderloin with a simple salt and pepper rub or marinate it in a mixture of herbs, spices, and oil for at least 30 minutes before grilling
- Preheat the grill to medium-high heat to ensure a nice sear on the pork tenderloin
- Grill the pork tenderloin for 15-20 minutes, turning occasionally, until it reaches an internal temperature of 145°F, then let it rest for 5-10 minutes before slicing and serving
Preparing the Pork Tenderloin for Grilling
Trimming and Drying the Meat
Before grilling a pork tenderloin, it’s essential to properly prepare the meat to ensure even cooking and a flavorful crust. Start by trimming any excess fat or silver skin from the surface of the pork tenderloin using a sharp knife. Removing excess fat will prevent flare-ups on the grill and allow the meat to cook more evenly. Additionally, removing silver skin, a tough connective tissue, will help seasonings and marinade penetrate the meat more effectively. Once trimmed, pat the pork tenderloin dry with paper towels to remove excess moisture, which can inhibit browning on the grill.
Butterflying the Meat (Optional)
After trimming and drying the pork tenderloin, consider whether you want to butterfly the meat before grilling. Butterflying involves cutting the pork tenderloin horizontally almost all the way through, then opening it like a book so that it lies flat. This technique can help the pork tenderloin cook more quickly and evenly on the grill, as well as provide more surface area for seasoning and developing a flavorful crust. If you choose to butterfly the pork tenderloin, be sure to do so carefully and evenly so that it cooks uniformly.
Letting the Meat Come to Room Temperature
Once the pork tenderloin has been prepared for grilling, it’s crucial to let it come to room temperature before cooking. Allowing the meat to come to room temperature will help it cook more evenly on the grill and result in a juicier and more tender finished product.
Setting Yourself Up for Success
By properly preparing the pork tenderloin for grilling, you can set yourself up for success and ensure that the meat cooks to perfection on the grill.
Seasoning and Marinating the Pork Tenderloin
Seasoning and marinating the pork tenderloin before grilling is essential for adding flavor and moisture to the meat. Start by generously seasoning the pork tenderloin with salt and pepper on all sides. The salt will help enhance the natural flavors of the meat, while the pepper will add a subtle heat and depth of flavor.
In addition to salt and pepper, consider adding other dry seasonings such as garlic powder, onion powder, paprika, or dried herbs like thyme or rosemary to further enhance the flavor of the pork tenderloin. After seasoning the pork tenderloin, consider marinating it for added flavor and moisture. A simple marinade can be made by combining olive oil, minced garlic, fresh herbs like rosemary or thyme, and citrus juice such as lemon or orange.
The acid in the citrus juice will help tenderize the meat and infuse it with flavor, while the oil will help keep the pork tenderloin moist during grilling. Marinate the pork tenderloin in a resealable plastic bag or shallow dish for at least 30 minutes, or up to 24 hours in the refrigerator for maximum flavor infusion. Another option for adding flavor to grilled pork tenderloin is to use a dry rub instead of a marinade.
A dry rub can be made by combining spices such as chili powder, cumin, brown sugar, and smoked paprika, then rubbing the mixture onto the surface of the pork tenderloin before grilling. The sugar in the dry rub will caramelize on the grill, creating a flavorful crust on the pork tenderloin, while the spices will add depth of flavor and a hint of smokiness. By seasoning and marinating the pork tenderloin before grilling, you can ensure that it develops a delicious crust and remains moist and flavorful throughout the cooking process.
Preheating the Grill
| Temperature | Time | Ideal Food |
|---|---|---|
| High heat (450-550°F) | 15-20 minutes | Steaks, burgers, seafood |
| Medium heat (350-450°F) | 10-15 minutes | Chicken, pork chops, vegetables |
| Low heat (250-350°F) | 5-10 minutes | Thicker cuts of meat, whole poultry |
Before grilling pork tenderloin, it’s important to properly preheat your grill to ensure even cooking and develop a flavorful crust on the meat. Start by cleaning your grill grates with a wire brush to remove any leftover food or debris from previous use. Then, preheat your grill to medium-high heat, around 375-400°F (190-204°C).
Preheating your grill to this temperature will help ensure that the pork tenderloin cooks evenly and develops a nice sear on the outside. If you’re using a charcoal grill, light your charcoal using a chimney starter or an electric starter until they are covered with white ash. Then spread them out in an even layer on one side of the grill to create two heat zones – one for direct heat and one for indirect heat.
If you’re using a gas grill, preheat it with all burners on high for about 10-15 minutes with the lid closed. Once your grill is preheated, use a grill brush to clean the grates and then oil them lightly with a paper towel dipped in vegetable oil to prevent sticking. By preheating your grill properly before cooking pork tenderloin, you can ensure that it cooks evenly and develops a delicious crust on the outside while remaining juicy and flavorful on the inside.
Grilling the Pork Tenderloin
Grilling pork tenderloin is a relatively quick and straightforward process that results in juicy, flavorful meat with a delicious crust on the outside. Once your grill is preheated to medium-high heat, place the seasoned and marinated pork tenderloin directly onto the grill grates. If you butterflied the pork tenderloin before grilling, be sure to lay it flat on the grill so that it cooks evenly.
Grill the pork tenderloin for about 5-7 minutes per side, rotating it 90 degrees halfway through each side’s cooking time to create an attractive crosshatch pattern of grill marks. Use tongs to carefully flip the pork tenderloin only once during cooking to ensure even browning and prevent sticking. If you’re using a charcoal grill with two heat zones, start by searing the pork tenderloin over direct heat for about 2-3 minutes per side until it develops a nice crust, then move it to indirect heat to finish cooking through without burning.
If you’re using a gas grill, simply reduce the heat to medium after searing both sides of the pork tenderloin. By grilling pork tenderloin over medium-high heat for about 5-7 minutes per side, you can achieve perfectly cooked meat with a flavorful crust on the outside while remaining juicy and tender on the inside.
Checking for Doneness
Ensuring Perfect Doneness
Checking for doneness is a crucial step when grilling pork tenderloin to ensure it is cooked through but still juicy and flavorful.
Using an Instant-Read Thermometer
The best way to check for doneness is by using an instant-read meat thermometer inserted into the thickest part of the pork tenderloin. The internal temperature should read 145°F (63°C) for medium-rare or 160°F (71°C) for medium doneness.
Alternative Method: The Visual Check
If you don’t have an instant-read thermometer, you can also check for doneness by making a small cut into the thickest part of the pork tenderloin with a sharp knife. The juices should run clear with no traces of pinkness, indicating that the meat is fully cooked.
Achieving Perfection
It’s important not to overcook pork tenderloin as it can quickly become dry and tough if cooked beyond medium doneness. By checking for doneness using an instant-read thermometer or by making a small cut into the meat, you can ensure that your grilled pork tenderloin is perfectly cooked and ready to be served.
Letting the Pork Tenderloin Rest and Serving
After grilling pork tenderloin to perfection, it’s important to let it rest before slicing and serving to allow the juices to redistribute throughout the meat. Transfer the grilled pork tenderloin to a cutting board or platter and loosely tent it with aluminum foil to keep it warm while it rests. Let the grilled pork tenderloin rest for about 5-10 minutes before slicing it against the grain into 1/2-inch thick slices.
Slicing against the grain will help ensure that each piece of pork is tender and easy to chew. Once sliced, serve the grilled pork tenderloin with your favorite sides such as roasted vegetables, mashed potatoes, or a fresh salad. Garnish with fresh herbs or a squeeze of citrus juice for added flavor and brightness.
By letting grilled pork tenderloin rest before slicing and serving, you can ensure that it remains juicy and flavorful while providing an impressive main course for your next meal.
