Step 1

Preheat oven to 325 degrees F (165 degrees C).

Step 2

In a 9x13 baking dish or large dutch oven, layer the onion slices on the bottom of the dish. Season with the sugar, 1 teaspoon salt, 1 teaspoon pepper and toss to coat onion slices in seasoning.

Step 3

In a small bowl, use a fork to mix 1 teaspoon salt and 1 teaspoon black pepper with the pressed garlic to make a garlic paste. Use the rest of the salt and pepper to season the meat generously on each side, then rub the garlic paste over each side of the roast. Place the seasoned chuck on top of the seasoned onion slices in your baking dish or dutch oven.

Step 4

Pour in beef broth or consomme, then put into the oven for 2 hours. Tent with aluminum foil or cover with oven-safe lid after 2 hours, for 30 minutes to 1 hour, until chuck roast is tender and barely holding together.

Step 5

Pull roast out; slice and shred the meat on a cutting board. Use a fine mesh sieve to strain the onions from the jus and save both the jus and onions separately.

Step 6

In the hoagie rolls, layer slices of cheese, onions, and meat. Place on baking sheets and put into the still warm, turned off oven. Melt the cheese, then remove from oven.

Step 7

Serve with jus on the side to dip into.
