Once prepped, add mirepoix to your hotel pan.
Take your filet mignon face down place in tray. Add salt, pepper, Montreal seasoning, molasses and some olive oil. Rub ingredients into the meat until the entire bottom is covered evenly.
Turn filet upright, laying the bottom on top of mirepoix. Add the ingredients and thoroughly rub all seasonings through out the top of the filet.* Remember you cannot season center of meat so don't be nervous give outer coating of seasoning a good rub.
Finally rub some minced garlic on top of the Chateaubriand and rub along entire meat. Set aside.
Peel about 3 to 4 potatoes.
Once peeled and washed cube potatoes to almost same size.
Place in Bowl and season with remaining ingredients. * Use the same seasonings as you used on the Chateaubriand.
Toss well and place the potatoes in the hotel pan along the sides of the Chateaubriand.
Place into a 400° degree oven and begin to roast you Chateaubriand along with vegetables.
