The cooking time for beef tenderloin on a gas grill can vary depending on the thickness of the meat and the desired level of doneness. As a general guideline, you can follow these cooking times:
- For a 1 to 1 1/2-inch thick tenderloin, grill for 12-15 minutes for rare (internal temperature of 125°F), 15-18 minutes for medium rare (130-135°F), or 18-20 minutes for medium (140-145°F).
- For a 2 to 3-inch thick tenderloin, grill for 20-25 minutes for rare, 25-30 minutes for medium rare, or 30-35 minutes for medium.
However, it’s always important to use a meat thermometer to ensure that the internal temperature of the beef tenderloin reaches the desired level of doneness. The thermometer should be inserted into the thickest part of the meat, and the internal temperature should be:
- 125°F for rare
- 130-135°F for medium rare
- 140-145°F for medium
After grilling, it’s recommended to let the meat rest for 10-15 minutes before slicing and serving. This will allow the juices to redistribute and make the beef tenderloin more tender and flavorful.
