French Dip French Fries

• 3 tablespoons all-purpose flour
• 2 cups whole milk, divided
• 2 ounces provolone cheese, grated (about 1/2 cup)
• 2 ounces Swiss cheese, grated (about 1/2 cup)
• 1 1/2 teaspoons kosher salt
• 1 teaspoon garlic powder
• 2 cups unsalted beef stock
• 1 beef bouillon cube
• 1 (1.1-oz.) envelope beefy onion soup mix (such as Lipton)
• 2 1/2 tablespoons olive oil, divided
• 1 small yellow onion, thinly sliced
• 1 1/2 teaspoons kosher salt
• 6 cups vegetable oil
• 1 (32-oz.) pkg. frozen steak fries
• 1/2 pound thinly sliced deli roast beef torn into 1- x 2-inch strips (such as Boar's Head)
• 1 1/2 tablespoons chopped fresh curly-leaf parsley
• 3/4 teaspoon coarsely ground black pepper

1. Prepare the Au Jus: Heat stock and bouillon in a small saucepan over high. Bring to a boil, and cook until reduced to 1 cup, 5 to 6 minutes. Whisk in soup mix, and boil, whisking often, until smooth, about 1 minute. Let stand 5 minutes. Strain; discarding any solids.
2. Prepare the Fries: Heat 1 1/2 tablespoons of the olive oil in a large skillet over high. Add onion; cook, stirring occasionally, until lightly browned, about 2 minutes. Lower heat to medium, sprinkle with 1/2 teaspoon of the salt, and cook, stirring often, until onions are softened, 8 to 10 minutes. Transfer onions to a plate.
3. Heat remaining 1 tablespoon olive oil in skillet over medium-high. Add roast beef; cook, stirring often, until browned and slightly crispy, 30 to 45 seconds.
4. Place fries on a serving platter. Top evenly with onions, roast beef, and 1 1/2 cups of the Cheese Sauce; drizzle with half of the Au Jus. Sprinkle with parsley and pepper. Serve with remaining Cheese Sauce and Au Jus on the side.
