🛒 Ingredients

For the Sliders

• 12 Hawaiian sweet rolls or slider buns

• 3 cups cooked shredded chicken (rotisserie chicken works great)

• 8 oz (225 g) fresh mozzarella, sliced

• 2 cups baby spinach

• 1 cup sautéed mushrooms, sliced

• ½ cup basil pesto

• 2 tbsp mayonnaise (optional, for extra creaminess)

Garlic Butter Topping

• 4 tbsp unsalted butter, melted

• 2 garlic cloves, minced

• 1 tsp Italian seasoning

• 1 tbsp grated Parmesan cheese

• 1 tbsp chopped fresh parsley

👩‍🍳 Instructions

Step 1 – Prepare the Rolls

1. Preheat the oven to 350°F (175°C).

2. Without separating the rolls, slice them horizontally into a top and bottom half.

3. Place the bottom half into a greased baking dish.

Step 2 – Build the Layers

1. Spread the pesto evenly over the bottom buns.

2. Add the shredded chicken in an even layer.

3. Top with sautéed mushrooms.

4. Arrange the fresh spinach evenly.

5. Layer the mozzarella slices over the vegetables.

6. If desired, spread a thin layer of mayonnaise on the inside of the top buns.

7. Place the top half of the rolls over the filling.

Step 3 – Make the Garlic Butter

1. Mix together:

   • Melted butter

   • Minced garlic

   • Italian seasoning

   • Parmesan cheese

   • Fresh parsley

2. Brush generously over the tops of the rolls.

Step 4 – Bake

1. Cover loosely with foil.

2. Bake for 15 minutes.

3. Remove the foil and continue baking for 8–10 minutes until the tops are golden and the cheese is fully melted.

4. Let rest for 5 minutes before slicing.

🍽️ Serving Suggestions

Serve these sliders with:

• Caesar salad

• Tomato basil soup

• Sweet potato fries

• Garlic parmesan fries

• Pickles

• Potato chips

💡 Tips for Success

• Rotisserie chicken saves time and adds great flavor.

• Fresh mozzarella creates the best cheese pull, but provolone or Monterey Jack also work well.

• Sauté the mushrooms first to remove excess moisture.

• Brush extra garlic butter on immediately after baking for an even richer finish.

• Let the sliders cool for a few minutes before cutting to keep the filling intact.

❄️ Storage

• Refrigerate leftovers in an airtight container for up to 3 days.

• Reheat at 325°F (160°C) for 10–12 minutes until warmed through.

• Freeze assembled (unbaked) sliders for up to 2 months. Bake directly from frozen, adding 10–15 minutes to the baking time.

🌿 Delicious Variations

• Add crispy bacon for extra smoky flavor.

• Swap pesto for sun-dried tomato spread.

• Use turkey instead of chicken.

• Add roasted red peppers for sweetness.

• Sprinkle crushed red pepper flakes for a spicy kick.

• Replace mozzarella with smoked provolone or Havarti cheese.
