Hot Roast Beef Sandwich (Quick French Dip!)

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 Hot Roast Beef Sandwich is one of our new favorites!

Instead of making a beef roast in the slow cooker or your crock pot, we’re using sliced 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 roast beef sandwiches, and it’s only going to take you 15 minutes!

How To Make A Hot Roast Beef Sandwich

All you need to do is get a good quality, sliced roast beef from your deli counter. Make sure the roast beef is on the rarer side because it will cook slightly in these sandwiches.

Next get a few sub rolls or hoagie rolls that will stand up to a 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.

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

Here’s the next trick to making these roast beef sandwiches even better. Season the roast beef with a sprinkle of 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 a homemade 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 cheesy beef sandwiches, and the best part is that we don’t need all day to make them!

More Sandwich Hacks!

Besides being one of the easiest dinners we can bring you already, there’s even more swap outs for getting these Hot Roast Beef Sandwiches on the table.

Instead of making the quick, homemade au jus, you can buy au jus dry powder packets right in the gravy aisle at the grocery store. And while you’re there…you can also use brown gravy if you want a thicker sauce than au jus.

Our Homemade Brown Gravy Recipe also works fabulous with these sandwiches, BTW.

Scale

Ingredients

  • 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

Instructions

  1. Preheat the broiler (for toasting the rolls and melting 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.

Recipe Notes

Note: To save even more time, buy powdered au jus packets in the gravy aisle at the grocery store.
