How to make Big Ass Roast Beef Sandwich with Bechamel Cheese Sauce Recipe - Big-Ass Sandwiches Recipe From Brian Wood Portland, Oregon

Makes 15 To 20 Sandwiches

ROAST BEEF:
5 lb (2.3kg) chuck roast
3 tbsp (45g) salt
3 tbsp (45g) pepper
3 tbsp (22g) onion powder
3 tbsp (22g) garlic powder

BÉCHAMEL CHEESE SAUCE:
1 cup (99g) all-purpose flour
1/2 cup (113g) butter
2 qt (1.9l) milk
2 1/2 lb (1.1kg) Tillamook Cheddar cheese, shredded
Pinch of sea salt and freshly ground pepper

FRENCH FRIES:
15 russet potatoes
6 cups (1410ml) vegetable oil
Sea salt to taste
15 to 20 ciabatta rolls

Method:
To make the roast beef, preheat the oven to 225°F (107°C, or gas mark ¼). Season the chuck roast with salt, pepper, onion powder and garlic powder. Place in a roasting pan and cook the beef for 45 minutes to 1 hour, until it reaches an internal temperature of 120°F (49°C). Let it cool for 24 hours. When ready to serve, thinly slice 4 ounces (112g) of the roast beef per sandwich and grill to a final temperature of 145°F (63°C).

To make the béchamel cheese sauce, stir together the flour and butter in a saucepan over low heat. Add the milk and stir until you have a smooth consistency. Add the cheese and stir constantly for approximately 40 minutes, until you have a velvety fondue consistency. Add a pinch of sea salt and black pepper to taste.

To make the fries, hand cut the potatoes into fries ¼ inch (6mm) thick. Pour the oil into a deep pot or fryer to a depth of 4 to 5 inches (10 to 15cm) and heat to 350°F (177°C) on a deep-fat thermometer. Add the fries in batches and cook until three-fourths of the way done; strain from the oil and cool. Reserve the oil in the pot, adding more to reach the same level as needed.

When ready to assemble the sandwiches, bring the oil back to temperature and fry the French fries again until cooked to your preferred crispness, strain and season with salt to taste.

Slice a ciabatta roll down one side like a clamshell. Place 4 ounces (113g) of roast beef on the bottom of the bread and top with a handful of fries. Pour ½ cup (120ml) of béchamel cheese sauce over the fries, add a few more fries and roll everything up in sandwich paper.
