Ingredients

• 4 Submarine sandwich rolls
• 1 pound Thinly sliced roast beef
• 2 cups Cheddar cheese, shredded
• 2 tablespoons Unsalted butter
• 1 Yellow onion, thinly sliced
• 0.5 cup Mayonnaise
• 2 tablespoons Dijon mustard
• 0.5 teaspoon Garlic powder
• 0.5 teaspoon Salt
• 0.25 teaspoon Black pepper
• 1 tablespoon Fresh parsley, chopped (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

In a small skillet over medium heat, melt the butter. Add the sliced yellow onions and cook, stirring occasionally, for about 8-10 minutes until the onions are caramelized and golden brown. Set aside.

Step 3

In a small bowl, whisk together the mayonnaise, Dijon mustard, and garlic powder. Set the mixture aside as a spread for the sandwiches.

Step 4

Slice the submarine rolls lengthwise, being careful not to cut all the way through, so they can be opened like a book. Lay them open on a baking sheet lined with parchment paper.

Step 5

Spread a generous layer of the Dijon mayo mixture on both sides of each roll.

Step 6

Divide the roast beef evenly among the four rolls, layering it generously on one side.

Step 7

Top the roast beef with the caramelized onions, followed by a generous sprinkle of shredded cheddar cheese.

Step 8

Season with salt and black pepper to taste.

Step 9

Close the sandwiches slightly and secure them with toothpicks, if needed. Cover the baking sheet with aluminum foil (this will help the cheese melt evenly) and bake in the preheated oven for 10 minutes.

Step 10

Remove the foil and bake for an additional 3-5 minutes, or until the cheese is fully melted and slightly bubbly.

Step 11

Remove the sandwiches from the oven and sprinkle with fresh parsley, if desired, for garnish.

Step 12

Serve the hot cheddar beef submarine sandwiches immediately and enjoy!
