Instructions
- Preheat your oven to 350ºF (180ºC or Gas 5).
- Make the Garlic Butter Sauce
- Whisk together the butter, worcestershire sauce, poppy seeds, white sesame seeds, garlic powder, minced onion, and salt and pepper together in a small bowl. Set aside for later.
- Make the Sliders
- Place the bottom halves of the slider buns onto your baking dish or rimmed baking sheet. Toast the buns for 2-3 minutes in the preheated oven and remove.
- Spread the aioli or mayonnaise over the bottom halves of the buns, then layer with the roast beef, slices of cheese, shredded mozzarella, and caramelized onions, if using.
- Top with the top halves of the slider buns, then use a pastry brush or silicone brush to slather the melted garlic butter sauce on top of the buns. Don't be stingy!
- Put the roast beef sliders into the preheated oven and bake for up to 15 minutes, until the tops are golden brown and the cheese is nice and melty.
- Cut between each slider with a serving spatula and serve with the rich, beefy au jus.
- Make the Beef Au Jus
- Melt the butter in a saucepan over medium-high heat.
- Whisk in the beef broth, beef base, and worcestershire sauce until well combined.
- Bring to a boil, then reduce to medium-low and simmer for about 15-20 minutes until the au jus reduces by half.
- Pour into a heat-safe bowl for dipping.
