A Recipe Hack For Busy Nights!

You know we love making a tasty pulled pork in the slow cooker – nothing beats those low and slow Pot Roast Recipes that you cook up for Sunday dinner. But we are busy people and we need recipes for busy nights and this French Dip Sandwich Hack is one of our new favorites!

Instead of making a beef roast in the slow cooker or your crock pot, we’re using regular roast beef right from the deli! There’s a few recipe hacks that we have to make regular roast beef taste unbelievably delicious in these french dip sandwiches, and it’s only going to take you 15 minutes!

How To Make These Easy French Dip Sandwiches

All you need to do is get a good quality, sliced roast beef from your deli counter. Thinner sliced roast beef will work best, but a normal slice will do. Next get a few sub rolls or hoagie rolls that will stand up to dipping in a quick au jus. I don’t recommend hot dog buns because they are too soft, but any kind of sub roll with work.

One of the best parts about french dip sandwiches is the au jus for dipping. For this French Dip Sandwich Hack recipe we’re using beef broth, shallots, fresh thyme and a splash of sherry to mimic a low and slow au jus that’s been cooking for hours.

Toast the rolls in a toaster oven or regular oven until slightly browned and then melt mozzarella cheese right onto the buns, top and bottom.

Here’s the next hack to making these quick french dip sandwiches, first we’re going to season the roast beef with steak seasoning to give it some flavor. We’re trying to mimic that low and slow roast beef flavor so adding your favorite steak seasoning will do the trick!

The next hack to making these beef sandwiches is that we’re going to take a pile of that roast beef and dip it right into the au jus before adding it to the toasted sub rolls.

Not only does it warm up the roast beef (which if it’s thinly sliced will happen very quickly) but it flavors the roast beef before adding it to the sandwich.

All that’s left to do is serve and dip. Our boys go absolutely crazy for these tender beef sandwiches, and the best part is that we don’t need all day to make them!

These easy beef sandwiches can be on the table in just 15 minutes! Perfect for busy nights parties and game day!



  • 1 pound sliced roast beef from the deli
  • Steak seasoning, kosher salt and black pepper
  • 1 tablespoon butter
  • 1 shallot, minced
  • 1 tablespoon flour
  • 1 teaspoon fresh thyme, chopped
  • 2 cups beef broth
  • 2 tablespoons sherry
  • 4 sub rolls
  • 16 slices mozzarella or provolone cheese


  1. Preheat the broiler to toast the rolls and melt the cheese. Alternately, you can use a toaster oven.
  2. Melt butter in a medium pot. Add shallot and cook over medium-low heat for 3-4 minutes until softened.
  3. Add fresh thyme and then sprinkle in the flour. Stir to combine with the shallots and then pour in the sherry and whisk together. Pour in the beef broth while whisking and then season the au jus with salt and pepper to taste. Bring to a boil and then turn down and let simmer until the sandwiches are ready.
  4. While the au jus is simmering, place the open sub rolls on a baking sheet and toast lightly under the broiler. Remove the rolls from the oven, add 2 slices of cheese to each side of each sub roll and then place back under the broiler for a minute or two to melt the cheese. Remove the rolls from the oven.
  5. Place the roast beef on a board, spreading out so that you can season the roast beef with the steak seasoning.
  6. Using tongs, dip the roast beef into the au jus and then divide between the 4 sub rolls. Serve with extra au jus on the side for dipping.
