Start by heating olive oil in a large skillet over medium heat. Dice the yellow onion and sauté until soft and golden. Add the ground beef to the pan along with paprika, garlic powder, salt, and black pepper. Cook for 7 to 10 minutes, breaking up the beef as it browns. Once cooked, drain off any excess grease.
1 pound ground beef, 1 teaspoon paprika, 1 teaspoon garlic powder, ¼ teaspoon salt, 1 medium yellow onion, 1 tablespoon olive oil, ¼ teaspoon black pepper
Stir in Worcestershire sauce and about half of the BBQ sauce. Let it simmer for another 2 minutes to soak up all the flavor, then remove from the heat.
1 tablespoon Worcestershire sauce, ¾ cup BBQ sauce
Preheat your oven to 350°F (180°C) and lightly grease a baking dish with nonstick spray. Slice the brioche slider buns in half horizontally and arrange the bottom halves in the baking dish.
1 12-count Brioche mini buns
Spoon the beef mixture evenly over each bun. Top with slices of pepper jack cheese, crumbled bacon, a drizzle of the remaining BBQ sauce, crispy fried onions, and thin slices of fresh jalapeño. Cap each slider with the top half of the bun.
6 slices pepper jack cheese, 6 slices bacon, ¼ cup crispy fried onions, 1 fresh jalapeño
In a small bowl, mix together the melted butter, minced garlic, parsley, red pepper flakes, onion powder, and fresh lemon juice. Generously brush this cowboy butter over the tops of the buns.
3 tablespoons unsalted butter, ½ teaspoon garlic, ⅓ teaspoon fresh parsley, ¼ teaspoon red pepper flakes, ½ teaspoon onion powder, ½ lemon juice
Bake the sliders for 12 to 15 minutes, or until the cheese is melted and the tops are golden brown and slightly crisp.
Serve warm and enjoy the spicy, smoky, cheesy goodness packed into each bite!
