Ingredients

8 slices white bread

1/4 c. unsalted butter, melted

16 c. slices provolone cheese (about 10 oz.)

1 c. slices thinly sliced deli roast beef (about 12 oz.)

1 c. French’s Fried Onions 

4 tbsp. French’s Classic Yellow Mustard

1 tbsp. unsalted butter

1 clove garlic, minced 

1/2 tsp. dried thyme leaves

1 1/2 c. low-sodium beef broth

1 tbsp. French’s Classic Yellow Mustard

1 tbsp. Worcestershire sauce

Kosher salt

Freshly ground black pepper

1 tbsp. freshly chopped chives

Preparation

Step 1Build the sandwiches: Arrange slices of bread in a single layer on a work surface. Brush the top sides of each piece of bread with the butter. Flip the bread so the butter side is face down on the surface. Top each piece of bread with 2 pieces of provolone cheese. Top half of the slices of bread with a layer of roast beef and drizzle with mustard. Sprinkle with french onions. Sandwich with the remaining pieces of bread with the provolone side in the sandwich and butter side facing out. Step 2Heat a large skillet over medium-low heat. Place 2 sandwiches in the skillet and cook until the bottom slice of bread is golden and the cheese is starting to melt, about 5 minutes. Carefully flip the sandwich and cook until golden underneath, about 5 minutes more. Repeat with remaining sandwiches. Step 3Meanwhile, make the au jus: Melt the butter in a medium skillet over medium heat. Stir in garlic and thyme; cook until fragrant, 1 to 2 minutes. Whisk in the beef broth, mustard, and Worcestershire sauce. Increase heat to high and bring to a boil. Season with salt, if necessary and pepper. Remove from heat and keep warm. Step 4Sprinkle the au just with chives and serve the hot sandwiches sliced with the warm au jus.
