Prep Time: 15 minutes

Total Time: 55 minutes

Ingredients  

  • 1 sweet onion diced
  • 3 tbsp butter
  • 20 oz shaved ribeye steak
  • 2 tsp Worcestershire sauce
  • 2 tsp beef base
  • 1 tsp BBQ rub
  • 4 Martin’s potato sandwich rolls
  • 8 oz Gruyère cheese shredded
  • sesame seeds for topping

Instructions

  • Melt 1.5 tablespoons of butter in a skillet over medium heat. Add the sliced onion and cook, stirring occasionally, until golden brown, about 20-25 minutes. Stir in the beef base and mix well.
  • Add the shaved ribeye steak directly to the skillet with the onions. Season with BBQ rub and Worcestershire sauce, then cook, stirring occasionally, until the steak is fully cooked. Remove from heat.
  • Split the potato rolls and place the bottom halves in a greased foil pan or cast iron skillet. Evenly distribute the steak and onion mixture over the buns, then top with shredded cheese. Place the top buns over the filling.
  • Melt the remaining 1.5 tablespoons of butter and brush it over the tops of the buns. Sprinkle sesame seeds on top if desired.
  • Preheat the smoker to 300°F. Place the pan or skillet in the smoker and cook for 20-25 minutes, until the cheese is melted and the buns are golden brown.
  • Remove the sliders from the smoker and let them rest for a couple of minutes. Serve warm and enjoy!

Notes

  • No Smoker? No problem—just bake them in the oven at 300°F for the same amount of time.
  • Customize the Cheese – Gruyère gives the sliders a classic French onion vibe, but provolone or white cheddar would work just as well.
  • Make Ahead Friendly – Caramelize the onions and cook the steak in advance, then assemble and smoke when ready to serve.
