Grilled Beef Tenderloin Recipe (So Easy You Won’t Believe it!)

Beef tenderloin is often referred to as an expensive cut of meat, and it is. In my house, a whole beef tenderloin only ever comes out for special occasions.

For these two reasons, this simple grilled beef tenderloin recipe is special to me. It’s not a beef fillet recipe that you are going to need a lot of ingredients or fancy cooking/grilling techniques for. This recipe only requires pantry staples and your charcoal or gas grill.

One of the most important parts of this recipe is a meat thermometer. A meat thermometer is crucial to perfectly grilled beef tenderloin. Any pitmaster will tell you that, and I’m sure you all know this already – but we do want to be safe!

Another simple technique this recipe uses is indirect grilling. This is so we don’t overcook or char the fillet. The last thing we want is our expensive beef tenderloin to taste like charcoal!

How long to grill beef tenderloin steak

Total grilling time will differ slightly depending on your grill, thickness of your steak, and your ideal doneness level.

In this recipe I use a 4 pound beef tenderloin and it took just over 40 minutes to reach my idea doneness temperature of 125 degrees Fahrenheit.

How do you grill a tenderloin steak on a gas grill?

To grill a whole beef tenderloin on a gas grill you don’t need to be an expert pit master or a professional chef. There is basically 3 steps you need to keep on top of.

  1. Searing
  2. Cooking
  3. Resting

Each of these steps is as important as the last.

Searing your beef fillet locks in the juices which keeps your beef juicy and tender. It also starts creating a crispy almost ‘bark’ on the outside of the fillet.

When cooking the beef it is essential to keep an eye on the temperature of your grill. You want to maintain an even cooking temperature in the cooking chamber. This ensures your beef will be cooked to your perfect doneness level.

Resting is just as important as the actual cooking of your meat. Resting your beef will let the juices re disperse through the meat and give you a more tender and juicy result. You should rest a beef fillet for at least 30 minutes for best results.

What temperature do you grill beef tenderloin steaks?

The internal temperature of your beef tenderloin is the most important part. It will make, or break your beef tenderloin. When cooking meat it is important that you have a meat thermometer handy. This will ensure you are coking to the perfect doneness every time.

Equipment

  • Gas or Charcoal Barbecue
  • Butchers twine
  • Scissors
  • Sharp knife
  • Meat thermometer

Ingredients

  • 1 whole beef fillet 4 – 5 pounds
  • 8 garlic cloves
  • 1/2 stick butter
  • 5 tbsp sea salt
  • 5 tbsp black pepper
  • 5 – 6 fresh rosemary sprigs
  • olive oil

Instructions

  • Trim the excess fat off the fillet with a sharp knife. Fold the thin end of the tip underneath the fillet so the fillet is around the same thickness throughout. Tie the folded end of the beef tenderloin together with butcher's twine, then tie the roast to the twine every 1/2 to 1 inches (to help the roast keep its shape while cooking). Snip the silverskin with scissors to keep the roast from bowing while cooking.
  • Pat dry your beef with a paper towel, then cover well with oil. Spread freshly cracked black pepper and sea salt on a plate of enough size to fit the fillet. Roll the fillet in the mixture so that it is well covered. You might need more salt and pepper depending on your taste buds.
  • Once the fillet is well seasoned, place your rosemary sprigs and whole garlic cloves on the plate and place your fillet on top. Cover and chill for up to 24 hours. Ensure that the temperature of your fillet is around 1 hour before cooking.
  • Either build a charcoal fire in half the grill or turn the burners over the barbecue grill according to your units manufacturers instructions. Use tongs to lubricate the grate with an oil-soaked rag or paper. Put beef on the hot side of your grill and close the lid. Grill until seared on each side, about 3 minutes per side.
  • Move meat to the cool side of the grill (if you only have 1 or two burners just sit the fillet to one side and keep one burner on medium).
  • In a medium sauce pan, melt half a stick of butter, 1 finely chopped rosemary sprig, 2 finely chopped gallic cloves and salt and pepper to taste. For the last 30 minutes of cooking time, baste the fillet 3 times with a mixture of melted butter.
  • Cook until your meat thermometer reads 125 degrees F in the centre of the thickest part for rare. Usually about 45 to 60 minutes, depending on the size of the filet and the grill.
  • Take off the grill and cover with foil and let the meat rest 15 minutes before slicing.
