Step-by-Step Instructions

Step 1: Prepare Your Zucchini Foundation
Preheat your oven to 375°F (190°C). Slice your zucchini into uniform ¼-inch rounds, then lay them on paper towels. Sprinkle generously with salt and let them rest for 10 minutes. This crucial step draws out excess moisture, preventing your Rotisserie Chicken Zucchini Casserole from becoming watery. Pat the zucchini dry before proceeding.
Pro Tip: Use a mandoline slicer for perfectly uniform zucchini rounds that cook evenly.
Step 2: Create the Aromatic Base
Heat olive oil in a large skillet over medium heat. Sauté the diced onion for 5-6 minutes until translucent and fragrant. Add minced garlic and cook for another minute, stirring constantly to prevent burning. This aromatic foundation enhances the overall flavor profile of your casserole.
Step 3: Prepare the Creamy Binding
In a large mixing bowl, whisk together heavy cream, beaten eggs, Italian seasoning, smoked paprika, salt, and pepper. This rich, custard-like mixture will bind all ingredients while creating that signature creamy texture that makes comfort food so satisfying.
Step 4: Layer Your Rotisserie Chicken Zucchini Casserole
Grease a 9×13-inch baking dish. Layer half the zucchini slices, overlapping slightly. Add half the shredded rotisserie chicken, then half the sautéed onion mixture. Sprinkle with ¾ cup mozzarella cheese. Repeat layers, then pour the cream mixture evenly over the top.
Step 5: Add the Golden Finish
Top with remaining mozzarella and all the Parmesan cheese. Cover with foil and bake for 30 minutes. Remove foil and bake an additional 15 minutes until the top is golden and bubbling, and a knife inserted in the center comes out clean.
Step 6: Rest and Garnish
Allow your Rotisserie Chicken Zucchini Casserole to rest for 10 minutes before serving. This resting period helps the layers set properly. Garnish with fresh basil and parsley for a burst of color and freshness.

Serving Suggestions

Your Rotisserie Chicken Zucchini Casserole pairs beautifully with various sides and presentation styles:
Serve alongside a crisp arugula salad dressed with lemon vinaigrette to balance the casserole’s richness. Roasted asparagus or steamed broccoli provide excellent vegetable companions while maintaining the low-carb theme.
For special occasions, present individual portions in ramekins for an elegant touch. Garnish each serving with fresh microgreens and a drizzle of herb-infused olive oil.
Consider offering warm, buttered cauliflower breadsticks as a carb-conscious alternative to traditional bread. The nutty flavor complements the casserole’s savory profile perfectly.
Common Mistakes to Avoid
Moisture Management: The most frequent error is skipping the zucchini salting step. According to culinary research, properly salted and drained zucchini reduces excess moisture by up to 40%, preventing soggy casseroles.
Temperature Control: Avoid cooking at temperatures above 375°F, which can cause the cream mixture to curdle and create an unpleasant texture in your Rotisserie Chicken Zucchini Casserole.
Overcrowding: Don’t pack ingredients too tightly. Proper layering with slight overlapping ensures even cooking and optimal texture.
Resting Period: Never skip the 10-minute resting period. This allows the casserole to set properly and makes slicing significantly easier.
Cheese Distribution: Uneven cheese distribution leads to inconsistent melting. Sprinkle cheese evenly across each layer for uniform coverage.
Storing Tips

Refrigerator Storage: Your Rotisserie Chicken Zucchini Casserole keeps beautifully for up to 4 days when covered tightly and refrigerated. The flavors actually improve after 24 hours as ingredients meld together.
Freezer-Friendly: This casserole freezes exceptionally well for up to 3 months. Wrap individual portions in plastic wrap, then aluminum foil for optimal protection against freezer burn.
Reheating Methods: For best results, thaw overnight in the refrigerator, then reheat covered at 350°F for 15-20 minutes. Microwave reheating works for single portions but may create slight texture changes.
Make-Ahead Strategy: Assemble your Rotisserie Chicken Zucchini Casserole completely, cover tightly, and refrigerate up to 24 hours before baking. Add 5-10 minutes to the original cooking time when baking from cold.
