Why You’ll Love This Recipe

My family loves beef. So when I went through my recipe box looking for inspiration I came across these easy French dip sandwiches that I have not made in a very long time. It’s one of our favorite sandwiches.

  • Starting with a can of French Onion Soup gives this hot sandwich so much flavor.
  • There is lots of melty cheese.
  • If you need extra au jus just doctor up a second can of soup.
  • It’s an easy recipe the whole family will enjoy.
  • The doctored-up soup makes the au jus sauce. No need for a separate au jus recipe.
  • The cooking time is quick, even with putting the sandwiches in the oven to melt the cheese.

Ingredients

  • Sliced Roast Beef – I get it in the deli section of my grocery store.
  • Worcestershire Sauce
  • Can of French Onion Soup
  • Water
  • Provolone Cheese
  • Hoagie Buns or Sub Rolls

What kind of cheese do you use in a French dip recipe?

There are many cheese choices for delicious French dip sandwiches. The best are melty cheeses such as Mozzarella cheese, Provolone cheese, or Swiss Cheese. I have been known to use a combination of Mozzarella and Provolone.

When I found this recipe in my recipe box, I doctored it up just a bit with the addition of Worcestershire sauce. Something my husband is not a big fan of but doesn’t notice in this recipe. It’s the umami flavor that makes this a delicious au jus.

I find the Worcestershire sauce adds a great flavor to the canned French onion soup. I’m not usually a fan of using canned soups but I do so for quick convenience. They can be a great beginning for sauces in some recipes.

Additions and Tips

You can make these French dip sandwiches with au jus your own with a few simple additions.

  • If you have time and want to take this sandwich up a notch, add caramelized onions.
  • Add a teaspoon of soy sauce to the soup for some added flavor in the warm au jus. Not too much because it’s salty.
  • Add a cube or teaspoon of beef bouillion to the soup mixture for an extra beefy flavor.
  • When you put the sandwiches in the oven, keep the au jus warm on the stove top over low to medium heat.

While this French dip sandwich recipe is super easy, you may just want dinner done after a long day at work. Try this crock pot version made with a chuck roast. Serve them on either a French roll or hoagie rolls.

This French dip crescent ring is a fun recipe and would be great for a crowd.

How do you serve hot au jus sauce for French dips?

I like to use ramekins to serve the au jus. The wider the better for dipping.

What To Serve With French Dip Sandwiches

Yummy sides for these sandwiches that are family-friendly include Fried Onion Strings which are similar to what you can get in a restaurant. Creamy coleslaw or potato salad are other good options for a heartier side dish.

Homemade french fries would be a classic side and what you might get with a delicious French dip sandwich in a restaurant.

Plantain chips and sweet potato chips are nice options instead of plain potato chips.

Everyone is going to love these roast beef sandwiches with melted cheese on crusty bread. The flavorful roast beef and savory au jus will make this a favorite meal.
