Are you a true barbecue aficionado aiming to master the art of cooking beef tenderloin on a charcoal grill? You're in the right place. Knowing how long to cook beef tenderloin on a charcoal grill can make all the difference between a meal that's just good and one that's downright unforgettable.

Understanding Your Beef Tenderloin
Before you fire up your grill, understanding the nuances of beef tenderloin is essential. Frequently referred to as the filet, its one of the most tender cuts of beef, perfect for grilling. Its delicate nature requires precise timing and careful handling to achieve that delectable balance of a smoky, crispy exterior and a juicy, tender interior.
The Perfect Grill Setup
The true magic of grilling lies in the setup. Start by choosing a quality charcoal grill. If you're still undecided or need recommendations, check out Webers guide on How to Use a Charcoal Barbecue. Arrange the charcoals for indirect heat; this allows you to cook the tenderloin evenly without the risk of burning the outer layer.
Direct vs. Indirect Heat
Grilling requires a balance between direct and indirect heat. For beef tenderloin, indirect heat is your best friend. Start the tenderloin on the hot side of the grill for a quick sear, then move it to the cooler side to finish cooking slowly. This two-step method ensures a beautifully charred crust without overcooking the insides.
How Long Is Enough?
So, how long should you cook your beef tenderloin? The cooking time varies depending on several factors, including the size of the tenderloin, the grill temperature, and your preferred level of doneness. Generally, a whole tenderloin, weighing around 4 to 5 pounds, cooked to medium-rare, will take about 25-30 minutes once the grill reaches a consistent temperature of 135F (57C).
Temperature Control Is Key
The secret to perfect beef tenderloin lies in temperature control. A meat thermometer is your best tool to achieve this. Insert the thermometer into the thickest part of the tenderloin without hitting the bone, if any. Aim for:
- 120F (49C) for rare
- 130F (54C) for medium-rare
- 140F (60C) for medium
This ensures the meat rests up to the desired temperature and retains all its natural juices.
Rest and Serve
Once you've achieved the perfect temperature, it's crucial to let the beef tenderloin rest. Tent it loosely with foil and allow it to sit for 10-15 minutes. This resting period lets the meat absorb the juices which help in amplifying the flavors when you finally carve it up to serve.
Pitfalls to Avoid
Avoid prodding or cutting the tenderloin too earlythis releases essential juices and dries out the meat. Similarly, resist the temptation to press down on the meat as it grills; this expels moisture and may result in a less tender dish.
