The tenderloin, often called the filet mignon when cut into individual steaks, is prized for its tenderness and delicate flavor. Grilling a 1-inch tenderloin offers a quick and delicious way to enjoy this premium cut. However, achieving that perfect balance of a beautiful sear and a juicy, perfectly cooked interior requires understanding grilling times and techniques. This guide will walk you through every step, ensuring you master the art of grilling a 1-inch tenderloin to perfection.
Understanding Tenderloin Thickness and Doneness
The key to successful grilling lies in understanding how thickness affects cooking time. A 1-inch tenderloin cooks significantly faster than a thicker cut. Knowing your desired doneness is equally crucial. Do you prefer rare, medium-rare, medium, or well-done? Each level requires a different internal temperature, and therefore, different grilling times.
Internal temperature is the most reliable indicator of doneness. Use a reliable instant-read thermometer to check the temperature at the thickest part of the steak. Avoid touching the bone, as this will skew the reading.
Here’s a quick reference for internal temperatures:
- Rare: 125-130°F
- Medium-Rare: 130-135°F
- Medium: 135-145°F
- Medium-Well: 145-155°F
- Well-Done: 155°F+
Keep in mind that the internal temperature will continue to rise slightly (carryover cooking) even after you remove the tenderloin from the grill. This is typically around 5-10°F, so aim to remove the steak from the grill when it’s about 5 degrees below your target temperature.
Preparing Your 1-Inch Tenderloin for Grilling
Preparation is paramount for achieving the best results. Starting with a high-quality tenderloin is essential. Look for steaks that are evenly thick, well-marbled (intramuscular fat), and bright red in color.
Before grilling, remove the tenderloin from the refrigerator about 30-45 minutes before cooking. This allows the meat to come closer to room temperature, promoting more even cooking. Pat the steak dry with paper towels. This helps create a beautiful sear.
Seasoning is a matter of personal preference. A simple salt and pepper seasoning is often all that’s needed to highlight the natural flavor of the tenderloin. However, you can also use more complex spice rubs or marinades. If using a marinade, be sure to pat the steak dry before grilling to prevent steaming.
For basic seasoning, generously season both sides of the tenderloin with kosher salt and freshly ground black pepper. Don’t be shy with the salt, as it helps draw out moisture and enhance the flavor.
Grilling Techniques for a 1-Inch Tenderloin
There are two primary grilling methods suitable for a 1-inch tenderloin: direct heat and a combination of direct and indirect heat.
Direct Heat Grilling
Direct heat grilling involves cooking the tenderloin directly over the heat source. This is ideal for achieving a quick sear and is well-suited for thinner cuts like a 1-inch tenderloin.
Preheat your grill to high heat (450-550°F). Make sure the grates are clean and lightly oiled to prevent sticking.
Place the seasoned tenderloin on the hot grill grates. Sear for 2-3 minutes per side, or until a dark, crusty sear develops.
Reduce the heat to medium (350-450°F) and continue cooking for another 2-4 minutes per side, depending on your desired doneness. Use an instant-read thermometer to monitor the internal temperature.
Direct and Indirect Heat Grilling
This method involves searing the tenderloin over direct heat and then moving it to a cooler part of the grill (indirect heat) to finish cooking. This helps prevent the outside from burning before the inside reaches the desired temperature.
Preheat your grill with two distinct heat zones: one side with high heat (450-550°F) for searing, and the other side with little to no heat (indirect heat).
Sear the tenderloin over direct high heat for 2-3 minutes per side, until a nice crust forms.
Move the tenderloin to the indirect heat zone and continue cooking until it reaches your desired internal temperature. This may take another 2-5 minutes, depending on the heat of the grill and your preferred doneness. Again, use an instant-read thermometer to monitor the temperature.
Grilling Time Guidelines for a 1-Inch Tenderloin
These times are estimates and will vary depending on the heat of your grill and the thickness of the steak. Always use an instant-read thermometer to ensure accurate doneness.
Direct Heat (High Heat Sear followed by Medium Heat)
- Rare: 4-6 minutes total (2-3 minutes per side searing, 2-3 minutes per side medium)
- Medium-Rare: 6-8 minutes total (2-3 minutes per side searing, 3-5 minutes per side medium)
- Medium: 8-10 minutes total (2-3 minutes per side searing, 5-7 minutes per side medium)
- Medium-Well: 10-12 minutes total (2-3 minutes per side searing, 7-9 minutes per side medium)
- Well-Done: 12-15 minutes total (2-3 minutes per side searing, 9-12 minutes per side medium)
Direct and Indirect Heat (High Heat Sear followed by Indirect Heat)
- Rare: 4-7 minutes total (2-3 minutes per side searing, 2-4 minutes indirect)
- Medium-Rare: 6-9 minutes total (2-3 minutes per side searing, 3-6 minutes indirect)
- Medium: 8-12 minutes total (2-3 minutes per side searing, 5-9 minutes indirect)
- Medium-Well: 10-14 minutes total (2-3 minutes per side searing, 7-11 minutes indirect)
- Well-Done: 12-16 minutes total (2-3 minutes per side searing, 9-13 minutes indirect)
Resting and Serving Your Grilled Tenderloin
Resting the tenderloin after grilling is essential for allowing the juices to redistribute throughout the meat. This results in a more tender and flavorful steak.
Remove the tenderloin from the grill and place it on a cutting board. Tent it loosely with foil and let it rest for 5-10 minutes.
After resting, slice the tenderloin against the grain. This shortens the muscle fibers, making the steak easier to chew.
Serve immediately and enjoy!
Tips for Grilling the Perfect 1-Inch Tenderloin
- Use a reliable instant-read thermometer: This is the most accurate way to determine doneness.
- Don’t overcrowd the grill: Grilling too many steaks at once can lower the temperature of the grill and result in uneven cooking.
- Avoid pressing down on the steak: This forces out the juices and dries out the meat.
- Use tongs to flip the steak: A fork can pierce the meat and release juices.

Troubleshooting Common Grilling Problems
Even with the best preparation, grilling can sometimes present challenges. Here are some common problems and how to solve them:
- Steak is burning on the outside but raw on the inside: This usually means the heat is too high. Lower the heat or move the steak to indirect heat to finish cooking.
- Steak is tough: Overcooking is the most common cause of a tough steak. Use an instant-read thermometer to avoid overcooking.
- Steak is not searing properly: Make sure the grill is hot enough and the steak is dry. Pat the steak dry with paper towels before seasoning.
- Steak is sticking to the grill: Make sure the grill grates are clean and lightly oiled.
Grilling a 1-inch tenderloin is a quick and rewarding culinary experience. By understanding the principles of heat control, cooking times, and proper techniques, you can consistently achieve perfectly grilled tenderloin that is both tender and flavorful. Remember to always use an instant-read thermometer to ensure accurate doneness and don’t be afraid to experiment with different seasonings and cooking methods to find your personal preferences.
What temperature should my grill be for grilling a 1-inch tenderloin?
For grilling a 1-inch tenderloin to perfection, it’s crucial to achieve a high heat level. Aim for a grill temperature of around 450-500°F (232-260°C). This high heat will allow you to quickly sear the outside of the tenderloin, creating a flavorful crust while keeping the inside juicy and tender. Using a grill thermometer is the best way to ensure you reach and maintain the ideal temperature.
Whether you’re using a gas or charcoal grill, make sure to preheat it thoroughly before placing the tenderloin on the grates. For gas grills, this means turning all burners to high. For charcoal grills, ensure the coals are evenly distributed and glowing red with a light ash coating. Proper preheating is vital for achieving the desired sear and preventing the tenderloin from sticking to the grill.
How long should I grill a 1-inch tenderloin for medium-rare?
Grilling a 1-inch tenderloin to medium-rare (internal temperature of 130-135°F) typically takes about 4-6 minutes total. This timeframe assumes a grill temperature of 450-500°F. Plan on grilling for approximately 2-3 minutes per side. Remember that these are just guidelines, and the actual cooking time can vary based on the grill’s efficiency and the surrounding weather conditions.
The best way to ensure your tenderloin is cooked to your desired doneness is to use a reliable meat thermometer. Insert the thermometer into the thickest part of the tenderloin, avoiding bone or fat. Monitor the internal temperature closely and remove the tenderloin from the grill when it’s about 5°F below your target temperature, as it will continue to cook slightly during the resting period.
What’s the best way to season a tenderloin before grilling?
Simple seasoning often works best for a tenderloin to highlight its natural flavor. A generous coating of kosher salt and freshly ground black pepper is a great starting point. You can also add garlic powder, onion powder, or paprika for extra flavor. For a bolder taste, consider using a dry rub with herbs like thyme, rosemary, or oregano.
Applying the seasoning at least 30 minutes before grilling allows the salt to penetrate the meat, resulting in better flavor and moisture retention. If you have more time, you can season the tenderloin up to 24 hours in advance and store it in the refrigerator. Just be sure to bring it to room temperature for about 30 minutes before grilling to ensure even cooking.
Should I sear the tenderloin over direct or indirect heat?
Searing the tenderloin over direct heat is crucial for developing a flavorful crust. Direct heat provides the high temperature needed to create the Maillard reaction, which is responsible for the browning and delicious flavor of the tenderloin. Position the tenderloin directly over the hottest part of the grill grates for the initial searing.
After searing both sides, you can move the tenderloin to indirect heat if you need to bring it up to the desired internal temperature without burning the outside. Indirect heat is achieved by turning off a burner on a gas grill or moving the coals to one side of a charcoal grill. This allows the tenderloin to cook more gently and evenly.
How important is it to let the tenderloin rest after grilling?
Resting the tenderloin after grilling is extremely important for retaining its juices and achieving a more tender result. After removing the tenderloin from the grill, let it rest for at least 5-10 minutes before slicing. Cover it loosely with foil to help retain heat without steaming the exterior.
During the resting period, the muscle fibers in the tenderloin relax, allowing the juices to redistribute evenly throughout the meat. This results in a more flavorful and tender eating experience. If you cut into the tenderloin immediately after grilling, the juices will run out, leaving you with a drier and less flavorful piece of meat.
What’s the best way to slice a grilled tenderloin?
To slice a grilled tenderloin properly, use a sharp carving knife and cut against the grain. Identifying the grain, which are the muscle fibers running in a specific direction, is crucial. Cutting against the grain shortens these fibers, making the meat more tender and easier to chew.
Hold the tenderloin firmly with a carving fork and slice it into even pieces, typically about 1/4 to 1/2 inch thick. Slicing thinly helps maximize tenderness and allows the flavors to be fully appreciated. Arrange the slices artfully on a serving platter and serve immediately for the best taste and presentation.
Can I use a marinade for a 1-inch tenderloin?
Yes, you can definitely use a marinade for a 1-inch tenderloin to enhance its flavor and tenderness. A good marinade typically contains an acid (like vinegar or lemon juice), oil, and seasonings. Marinating the tenderloin for at least 30 minutes or up to several hours can significantly improve its taste and texture.
However, be mindful of acidic marinades, as prolonged exposure can make the tenderloin mushy. It’s generally recommended to marinate for no more than 2-4 hours to avoid over-tenderizing the meat. Always discard any remaining marinade after use and avoid using it as a sauce, as it has been in contact with raw meat.
