Bring home the taste of Quiznos Steakhouse Dip Sandwich with my easy recipe. No-Cream Alfredo Sauce is used to make the "secret" sauce which gives the sandwich its satisfying and delicious taste. If you like Quiznos you'll like this!

Ingredients Nutrition

  • 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 cup mayonnaise
  • 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


  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.

This got a thumbs up from the 15 year old food critic at my house. I forgot to buy alfredo sauce, so we omitted the secret sauce, but he still gobbled up his sandwich and had leftovers for lunch the next day. Thanks for a great recipe.
