Creating Quick Rotisserie Chicken Zucchini Casserole is an easy process that anyone can follow. Just stick to these simple steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking.
2. Prepare Zucchini: Slice the zucchinis into thin rounds. You can use a mandoline for even slices.
3. Sauté Zucchini: In a skillet over medium heat, lightly sauté the zucchini slices for 3-4 minutes. This helps soften them and reduce excess water.
4. Mix Chicken and Cheeses: In a large mixing bowl, combine the shredded rotisserie chicken, ricotta cheese, half of the mozzarella cheese, Italian seasoning, garlic powder, salt, and pepper. Stir until well mixed.
5. Layer Zucchini: Spread a thin layer of marinara sauce at the bottom of a greased 9×13 inch baking dish. Place half of the sautéed zucchini slices evenly over the sauce.
6. Add Chicken Mixture: Spoon half of the chicken and cheese mixture over the zucchini layer. Spread evenly.
7. Repeat Layers: Add another layer of marinara sauce, the remaining zucchini, and the rest of the chicken mixture. Finish with a final layer of marinara sauce.
8. Add Topping: Top the last layer with the remaining mozzarella cheese, ensuring everything is covered for a cheesy finish.
9. Bake: Cover the casserole with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes or until the cheese is bubbly and golden.
10. Cool and Serve: Once done, remove the casserole from the oven and let it cool for a few minutes. Garnish with fresh basil if desired.

Following these steps will result in an incredible Quick Rotisserie Chicken Zucchini Casserole ready to serve to family and friends.
