Ingredients

• 12 oz uncooked penne or rigatoni
• 2 cups shredded cooked chicken (rotisserie works great)
• 2 cups marinara sauce (San Marzano or your favorite)
• 1 ½ cups shredded mozzarella cheese
• ½ cup freshly grated Parmesan cheese
• ½ cup panko breadcrumbs
• 2 Tbsp olive oil
• 1 tsp dried oregano
• ½ tsp garlic powder
• Salt & pepper to taste
• Fresh basil leaves for garnish (optional)

Directions

1. Preheat the oven to 400°F (200°C). Lightly grease a 9‑x‑13‑inch baking dish with a drizzle of olive oil.
2. Cook the pasta in a large pot of salted boiling water until al dente, about 9‑10 minutes. Drain and set aside.
3. Season the chicken – in a bowl, toss shredded chicken with oregano, garlic powder, salt, and pepper. This adds a subtle herbaceous note that mimics the classic Chicken Parmesan seasoning.
4. Combine the base – in the same pot used for pasta, heat 2 Tbsp olive oil over medium heat. Add the cooked pasta, seasoned chicken, and marinara sauce. Stir until everything is evenly coated.
5. Transfer to the baking dish – spread the mixture evenly, pressing gently to create a compact layer.
6. Add the cheese – sprinkle mozzarella evenly over the top, followed by a generous shower of grated Parmesan.
7. Prepare the crunchy topping – in a small bowl, mix panko with a drizzle of olive oil, a pinch of salt, and a little extra Parmesan. Sprinkle this mixture over the cheese for a golden‑brown crust.
8. Bake for 20‑25 minutes, or until the cheese is bubbling, the edges are lightly browned, and the panko topping is golden.
9. Rest and garnish – remove from the oven and let the casserole sit for 5 minutes. Garnish with fresh basil leaves for a pop of color and aroma.
10. Serve hot, scooping generous portions onto plates. Pair with a simple green salad or garlic‑bread for a complete meal.

Pro Tips & Tricks

Variations & Substitutions

One of the joys of this casserole is its adaptability. Below are some creative twists to suit different tastes and dietary needs:

• Low‑Carb Version: Replace the pasta with spiralized zucchini or cauliflower rice. Reduce bake time by 5‑7 minutes.
• Gluten‑Free: Use gluten‑free pasta and panko made from rice flour.
• Vegetarian: Swap chicken for roasted eggplant cubes or sautéed mushrooms. Add a can of chickpeas for extra protein.
• Spicy Kick: Stir in 1‑2 teaspoons of harissa paste or chopped jalapeños into the marinara.
• Herb‑Infused: Mix fresh chopped oregano, thyme, or rosemary into the breadcrumb topping.
• Cheese Blend: Combine mozzarella with provolone or fontina for a richer melt.

Storage & Reheat

Refrigeration: Store leftovers in an airtight container for up to 4 days. Reheat in the oven at 350°F (175°C) for 15‑20 minutes, or microwave individual portions for 2‑3 minutes, covering with a damp paper towel to retain moisture.

Freezing: Cool the baked casserole completely, cut into serving squares, wrap each piece in plastic wrap followed by foil, and freeze. To serve, bake from frozen at 375°F (190°C) for 25‑30 minutes, or thaw overnight in the fridge and bake for 20 minutes.

Make‑Ahead: Assemble the uncooked casserole (up to the breadcrumb topping), cover tightly, and refrigerate up to 24 hours. Bake directly from the fridge, adding an extra 5 minutes to the bake time.

Frequently Asked Questions

Can I use fresh chicken breasts instead of shredded rotisserie?

Absolutely. Poach or bake two boneless, skinless breasts, let them cool, then shred or dice. This adds a few extra minutes to prep but gives you control over seasoning.

What if I don’t have panko?

Regular breadcrumbs work fine, though panko yields a lighter, crispier crust. You can also crush cornflakes or use crushed tortilla chips for a different texture.

Is this casserole gluten‑free?

Yes, by swapping regular pasta and panko for gluten‑free alternatives. Ensure your marinara sauce is also gluten‑free.

Can I add vegetables?

Definitely! Spinach, roasted red peppers, zucchini ribbons, or even peas blend nicely. Add them after mixing the pasta and sauce, before the cheese layer.

How do I prevent the cheese from becoming rubbery?

Avoid over‑baking. Remove the casserole when the cheese is bubbly and just turning golden. Letting it rest for a few minutes also helps set the cheese without over‑cooking.
