Baked Chicken-Parmesan Sliders for Parties

Golden roll tops, bubbling mozzarella, and warm marinara make these Baked Chicken-Parmesan Sliders for Parties especially inviting when they come out of the oven. Each slider combines crispy breaded chicken, thick tomato sauce, two layers of low-moisture mozzarella, Parmesan, and a buttery garlic topping.

Using packaged chicken tenders keeps preparation manageable, while the cheese layers help protect the rolls from excess moisture. The recipe makes 12 individual sliders, so it fits naturally on a game-day table or casual party spread.

Why You’ll Love This Recipe

• Makes 12 substantial sliders for a party appetizer or casual meal.
• Uses fully cooked breaded chicken tenders for crispy texture and easier preparation.
• Places mozzarella below and above the filling to help control moisture.
• Bakes in one 12×8-inch dish for convenient serving.
• Finishes with golden roll tops, melted cheese, and savory garlic butter.

Ingredients

For the Sliders

• 1 package (26 oz / 737 g) frozen crispy breaded chicken tenders or breaded chicken-breast cutlets, cooked according to package directions
• 12 standard slider rolls, preferably sturdy bakery, brioche-style, or Sara Lee Artesano-size rolls
• 12 slices low-moisture mozzarella cheese, approximately 8 oz / 227 g total
• 1 cup (240 mL) thick marinara sauce, divided, plus additional warmed sauce for optional dipping
• 2 Tbsp finely grated Parmesan cheese, approximately 10 g, divided
• 1–2 Tbsp chopped fresh Italian parsley, approximately 4–8 g, for optional garnish
• Nonstick cooking spray for the baking dish

Use thick marinara rather than a loose, watery sauce. Low-moisture sliced mozzarella is also important here because fresh mozzarella contains more water and can leave the bread soggy.

For the Garlic-Butter Topping

• 4 Tbsp (57 g) salted butter, melted
• 3 medium garlic cloves, finely minced, approximately 1 Tbsp or 9 g
• ½ tsp onion powder
• ½ tsp dried Italian seasoning or dried oregano
• ½ tsp crushed red pepper flakes

How to Make This Recipe

Step 1: Cook the Chicken

Cook the frozen breaded chicken tenders on a sheet pan according to the package directions. Because cooking times vary by brand and tender size, follow the package rather than using one fixed time. Once the chicken is fully cooked and crisp, let it cool for about 5 minutes, just until it’s comfortable to handle.

Pro Tip: Don’t assemble the sliders with frozen chicken. The rolls may overbrown before the chicken is properly heated.

Step 2: Prepare the Rolls and Garlic Butter

Preheat a conventional oven to 350°F (177°C), then lightly coat a 12×8-inch baking dish with nonstick cooking spray. Mix the melted butter, minced garlic, onion powder, Italian seasoning, and crushed red pepper flakes in a small bowl. Slice the rolls horizontally, place the bottom halves in the dish, and brush them with some of the garlic butter.

Cover the roll bottoms with 6 mozzarella slices, then spread ½ cup marinara evenly over the cheese.

Pro Tip: Keep the mozzarella directly against the bottom rolls. This cheese layer creates a barrier between the bread and sauce, helping prevent soggy bottoms.

Step 3: Assemble the Sliders

Arrange the cooked chicken evenly over the sauced cheese, trimming pieces only when needed so all 12 sliders receive chicken. Drizzle the remaining ½ cup marinara over the chicken, sprinkle with 1 Tbsp Parmesan, and cover with the remaining 6 mozzarella slices.

Place the roll tops over the filling. Brush them evenly with the remaining garlic butter and finish with the remaining 1 Tbsp Parmesan.

Step 4: Bake, Cut, and Serve

Loosely cover the baking dish with foil and bake for 20 minutes. Remove the foil and continue baking for 3–5 minutes, until the mozzarella is completely melted, the cheese near the edges bubbles gently, and the roll tops are lightly golden rather than deeply brown.

Garnish with chopped parsley, if using. Cut between the roll divisions with a sharp knife and serve warm with additional heated marinara, if desired.

Pro Tip: Serve the sliders shortly after baking. Letting the warm sauce sit against the bread for too long will gradually soften the bottoms.

Expert Tips for Better Results

• Choose sturdy, standard-size slider rolls that can support the chicken tenders without falling apart.
• Use low-moisture sliced mozzarella, not fresh mozzarella, to limit excess water in the filling.
• Keep the marinara measurement to 1 cup and use a thick sauce; adding more can make the rolls wet.
• Spread the filling evenly so every cut slider contains a similar amount of chicken.
• Use a light-colored ceramic, glass, or light-metal dish to encourage controlled browning.
• Look for fully melted cheese and lightly golden tops instead of relying only on the timer.

Variations

Using breaded chicken-breast cutlets instead of breaded tenders, dried oregano instead of Italian seasoning, or 1 tsp granulated garlic instead of the three fresh garlic cloves.

Serving Suggestions

• Serve the sliders with warm marinara for dipping without adding more moisture inside the sandwiches.
• Pair them with a crisp green salad to balance the rich cheese and breaded chicken.
• Add a simple pasta salad for a casual party or game-day buffet.
• Serve them beside french fries or potato chips for an easy, familiar meal.
• Pair two sliders with roasted vegetables when serving them as a more substantial dinner.

Storage and Reheating

Don’t leave the sliders at room temperature for more than 2 hours. If they’re served outdoors above 90°F (32°C), refrigerate them within 1 hour unless they’re held safely above 140°F (60°C).

Transfer leftovers to a shallow airtight container and refrigerate them for up to 3 days. For longer storage, cool the sliders completely, wrap them in plastic wrap and aluminum foil, and freeze for up to 2 months. Thaw frozen sliders overnight in the refrigerator before reheating.

Reheat refrigerated or thawed sliders in a 350°F (177°C) oven, loosely covered with foil, for approximately 10–15 minutes. The center must reach 165°F (74°C). Individual sliders can be reheated in an air fryer, although the approved source doesn’t provide an exact setting or time.

Microwaving is safe when the filling reaches 165°F, but it will soften the rolls and breaded coating. Freezing may also produce softer bread because the sauce and cheese release moisture as they thaw.
