French Dip with Au Jus
Pinterest Hidden ImagePinterest Hidden Image

Roast beef and prime rib are so delicious! These are cuts of meat I really appreciate and savor 😋 every time I have them. This is also an easy meal to serve when you are hosting a dinner. Last month just before Easter weekend, I posted my Roast Beef with Fresh Herbs an easy and flavorful dish to serve for any special occasion!
 
When I buy a roast, I love to get one bigger than I actually need because of the leftovers. The next meal is super easy and super-fast to prepare because all the cooking is already done. I just reheat a few slices of roast beef in the pan with some gravy and serve with a couple side dishes… tada! Although I really like it that way, there’s another dish I really, really love to make 👩‍🍳 from it and it’s my French Dip with Au Jus… oh my!
 
The combination of ingredients makes this sandwich 🥪 one of my favorites because it elevates the flavors and believe me, this sandwich is a winner! David knows his French Dip and he thinks mine is the best… pat on the back, thank you! I also use my homemade horseradish to spread on the hoagies… yum!
 
If you have leftovers from your roast beef then you’re in for a treat with this delicious, tasty sandwich along with the homemade Au Jus. Both are simple to put together and you’ll have a meal to enjoy in next to no time. I’m positive next time you are at the grocery store, you’ll buy 🛒 a bigger roast just so you have an excuse to make this French Dip with Au Jus recipe… it’s that good!
Bon Appétit!🍽

Ingredients
  

AU JUS

  • 1/2 tbsp. olive oil tips & tricks
  • 1/4 cup red onions, chopped
  • 1 large clove garlic, pressed
  • 1/4 cup dry red wine
  • 2 tsp. Worcestershire sauce
  • 1/2 tbsp. whole mixed peppercorns
  • 1 sprig rosemary tips & tricks
  • 1 sprig thyme
  • 2 cups low-sodium beef stock
  • 1 tbsp. cooking sherry
  • 2 tsp. granulated beef bouillon

FRENCH DIP

  • 1 tbsp. butter
  • 3 small hoagies
  • 1/2 cup red onions, sliced (Lyonnaise cut) tips & tricks
  • 1 large clove garlic, pressed
  • 1 1/2 lbs. (750g) roast beef, thinly sliced see Recipe
  • Dijon mustard, as needed
  • hot cream horseradish, as needed see Recipe
  • 6 slices Jarlsberg cheese (2 slices per hoagie)

Directions
 

AU JUS

  • In a medium pot over medium heat, add oil. When it gets hot, add onions and sauté until translucent, about 3-4 minutes. Add garlic and sauté for 1 minute.
  • Pour in red wine, Worcestershire sauce, peppercorns, sprigs of rosemary and thyme. Stir and let it simmer for 2 minutes.
  • Add beef stock, stir and bring to a boil. Reduce the heat to medium and simmer for 5 minutes.
  • Add sherry and granulated beef bouillon; stir and simmer gently for 20 minutes (might have to reduce to medium-low).
  • When it's done, strain the liquid into a large measuring cup through a fine sieve; discard solids. Return the liquid to the pot and keep it warm until needed.

FRENCH DIP

  • Slice hoagies in half but not all the way through – just enough to open them. Close them and transfer to the oven under the broiler for 2 minutes; this will make the crust crispier. Remove and cool them off.
  • In a skillet over medium heat, add butter. When melted, add sliced onions and sauté until soft, about 3 minutes.
  • Add garlic and quickly sauté for 30 seconds.
  • Add sliced roast beef and cook, stirring constantly, until warmed through and cook to medium, about 3 minutes. Remove from the heat.

SANDWICH

  • Spread Dijon mustard on both sides of the hoagies followed with horseradish. Add a slice of cheese per side and set aside.
  • Return the skillet to the heat and add about ¼ cup of au jus. Stir to combine making sure the beef is well-coated; turn off the heat.
  • Transfer the hoagies back to the oven and cook under the broiler until the cheese is melted, about 2 ½ minutes.
  • Remove from the heat and assemble the sandwich...
    Place warm roast beef in hoagie (*see footnote) and transfer onto a plate. Ladle au jus into a small bowl and place on the plate as a dip for the sandwich.

Notes

Footnote: It's roughly 1/2 lb. beef per hoagie.
