slice beef tenderloin

Step 1:
Either have your butcher cut the beef tenderloin slices for you or place the beef on a cutting board and carefully cut as many 1/2" slices as you'll need.

Depending on the size of the beef you're slicing, I recommend using at least 2 slices of grilled steak on each side of a split bun to make a full sandwich.

Step 2:
Place the sliced beef tenderloin in a resealable plastic bag.

Prepare the grilled steak marinade by mixing the ingredients above in a small jar.

Pour the steak marinade into the bag, seal the bag and mix well so all the beef is covered.

Place the bag in a shallow dish just in case the bag leaks and place it in the refrigerator for 2 - 4 hours.

Step 3:
Clean and oil the grates of your BBQ and preheat to 600F - 650F.

When the grill reaches this temperature range remove the slices of beef from the marinade and place on the grates.

Discard the steak marinade.

Close the lid for about a minute.

After a minute lift the lid and begin flipping the slices of grilled steak slices over.

Important - these slices are only 1/2" thick so they hardly take any time at all to cook.

Close the lid and leave for another minute.

Remove the grilled steak from the BBQ and place in a shallow dish and cover with aluminum foil to keep warm and to allow the juices to redistribute back into the meat.

Keep the grilling going to toast the buns next...

Step 4:
Split the soft panini or hoagie buns in half and brush with the melted garlic butter.

Put the buns, buttered side down, on the hot grill.

Don't leave these unattended - they take less then a minute to cook.

After 30 seconds lift a corner of a bun to see how it's doing.

When they're nicely toasted (and have those cool grill marks) then remove them from the grill.

Step 5:
Place the toasted buns on a baking sheet.

Preheat your oven broiler to 500F.

Place at least two slices of the grilled steak on each piece of toasted bun.

steak and mushrooms on a bun

If using the optional mushroom and onions for topping this steak sandwich recipe then:

  • melt 1/4 cup of butter in a frying or saute pan
  • add the sliced mushrooms and/or onions
  • when browned, add 1/4 cup red cooking wine until reduced
  • add 1/4 cup balsamic vinegar until reduced
  • sprinkle with a little fresh ground black pepper

    Spread the cooked mushrooms and/or onions on top of the grilled steak.

how to melt cheese on steak bun

Lay slices of Swiss cheese (or your favourite) on top of the steak, mushrooms and onions.

Shredded cheese is an option for this steak sandwich recipe but doesn't produce an evenly melted top like the sliced cheese does.

Place the baking sheet with this sandwich under the preheated broiler of your oven just until the cheese is melted.

Remove from the oven and serve immediately.
