🛒 Ingredients
- 1 lb: Thin-sliced roast beef (deli style)
- 4: Premium onion buns
- ½ cup: Gourmet beef broth
- 2 tbsp: Unsalted butter (divided)
- 1 jar (10–12 oz): Artisan cheddar cheese sauce
- To taste: Coarsely cracked black pepper
🍳 Method
- Toast the Buns: Split the onion buns in half. Melt 1 tablespoon of the unsalted butter in a large skillet or cast-iron pan over medium heat. Place the buns cut-side down in the pan and toast for 1 to 2 minutes until golden brown, warm, and slightly crisp. Remove them from the skillet and set aside.
- Simmer the Roast Beef: In the same skillet, melt the remaining 1 tablespoon of butter over medium-high heat. Add the thin-sliced roast beef to the pan, breaking up any clumped layers gently with tongs. Pour the beef broth evenly over the top of the meat and season generously with coarsely cracked black pepper. Simmer for 2 to 3 minutes, tossing continuously, until the beef absorbs the rich broth and becomes completely hot, tender, and juicy.
- Warm the Cheese Sauce: While the beef is simmering, gently warm your cheddar cheese sauce in a small saucepan over low heat (or in a microwave-safe bowl) until it reaches a smooth, hot, and easily pourable consistency.
- Assemble the Sandwich: Place the toasted bottom halves of the onion buns onto your serving plates. Use tongs to lift a generous portion of the steaming, juicy roast beef out of the skillet, letting any excess broth drain off slightly, and pile it high onto each bun base.
- Sauce and Serve: Pour a heavy blanket of the warm cheddar cheese sauce directly over the piled meat layers. Top with the toasted onion bun crowns, press down gently to let the cheese cascade down the sides, and serve immediately while hot.
