READY IN: 10mins


  • Optional Au Jus Dipping Sauce
  • 1
    tablespoon butter
  • 1
    tablespoon finely chopped onion
  • 1
    tablespoon flour
  • 1
    (1 ounce) packet au jus mix
  • 1 23
    cups water
  • Secret Sandwich Sauce
  • 12
    cup prepared alfredo sauce
  • 14
  • 1
    dash onion salt or 1 dash garlic salt
  • Sandwich
  • 1
    loaf bakery French bread
  • 34
    lb thin-sliced deli roast beef
  • 12
    cup shredded swiss cheese
  • 12
    cup shredded Italian cheese blend


  • Prepare the au jus dipping sauce: Melt butter in saucepan; saute onions until tender; add flour and stir; add contents of gravy mix packet then gradually whisk in water; allow to simmer while you make the sandwich.
  • Prepare the "secret" sauce: Stir together alfredo sauce, mayonnaise, and your choice of onion salt or garlic salt; slice french bread with one horizontal slice to make a top and a bottom half; spread "secret" sauce evenly over both pieces of sliced bread.
  • Place the prepared sandwich halves (open-faced) upon a baking sheet under the oven broiler for about 1 minute until the sauce is bubbly and the edges of the bread barely start to brown; remove from oven.
  • Arrange thin sliced roast beef over both sandwich halves then sprinkle evenly with shredded cheeses; broil for another minute (still open-faced) until cheese is bubbly all over and starting to brown; remove from oven.
  • Put sandwich halves together and return to oven to lightly toast (very, very briefly only) top and bottom of sandwich; remove from oven and slice sandwich into 5 even servings; provide 1/3 cup au jus with each serving.
  • NOTE: I usually make this sandwich using one large loaf of bakery french bread ~ You could go with smaller baguette buns if you want yours to taste AND look like the Quiznos Steakhouse Dip Sandwich.
