Step 1

Preheat oven to 350˚F. Butter a rimmed baking sheet.

Step 2

Place a large skillet over medium/high heat with 1 Tbsp olive oil and 2 Tbsp butter. Add sliced onion and Sauté over medium heat for 5 minutes until softened, stirring occasionally. Sprinkle with 1/4 tsp sugar and sautee uncovered 5 minutes until caramelized and golden, stirring often. Transfer to a plate.

Step 3

In the same pan, add 2 1/2 cups water and scrape the pan to deglaze. Add the au jus seasoning (adding to taste*) then bring to a boil, reduce heat and simmer according to package instructions. Add more water to taste if it’s too salty.

Step 4

Cut buns in half. Place the bottom half of dinner rolls on a buttered baking sheet and spread 1/4 cup mayo. Layer folded slices of beef evenly over the rolls. Spread caramelized onions over your sliders. Cover the beef with sliced provolone.

Step 5

Place the top of buns over and brush the tops with 2 Tbsp melted butter then immediately sprinkle tops with sesame seeds. Bake uncovered at 350˚F for 12-15 minutes, or until cheese is melted and tops are golden brown.

Step 6

Cut through the buns with a serrated knife to separate into individual sliders. Serve with warm au jus dip.
