Ingredients List

• 12 slider buns, halved
• 1 lb (450 g) ground beef or cooked shredded chicken
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 cup cheddar cheese, shredded
• 1 cup mozzarella cheese, shredded
• 1/2 cup cream cheese, softened
• 1/4 cup mayonnaise
• 1 teaspoon Dijon mustard
• 1/2 teaspoon smoked paprika
• 1/4 teaspoon black pepper
• Salt, to taste
• 2 tablespoons butter, melted
• Optional: chopped parsley for garnish

Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.

Step 2: Cook the Meat

In a skillet over medium heat, sauté onions and garlic until fragrant. Add ground beef or shredded chicken, season with salt, pepper, and smoked paprika, and cook until browned (skip browning for pre-cooked shredded chicken).

Step 3: Prepare the Cheese Mixture

In a medium bowl, combine cream cheese, mayonnaise, half of the shredded cheddar, and half of the mozzarella. Mix until smooth and creamy.

Step 4: Assemble the Casserole

Layer the bottom halves of slider buns in the prepared baking dish. Spread the cheese mixture evenly over the buns. Top with the cooked meat mixture, then layer the remaining buns on top. Sprinkle remaining cheddar and mozzarella over the top. Drizzle melted butter evenly across the casserole.

Step 5: Bake

Bake uncovered for 20-25 minutes until cheese is bubbly and golden. Allow casserole to rest for 5 minutes before serving. Garnish with chopped parsley if desired.
