Chicken Parmesan Casserole Dish

This chicken parmesan casserole transforms a classic Italian favorite into a convenient, family-friendly dish without sacrificing any of the traditional flavors. Each bite delivers that perfect combination of tender chicken, tangy marinara, and gooey cheese that makes chicken parm so beloved, but in an easy casserole format that's ready in just 40 minutes.

I created this recipe during a particularly hectic week when I needed something simple but satisfying for my family. Now it's become our go-to comfort food that even my pickiest eater requests regularly.

Ingredients

• Rotisserie chicken: The pre-cooked meat saves tremendous time while adding incredible flavor. The slight smokiness enhances the overall dish.
• No-added sugar marinara sauce: The foundation of authentic flavor without unnecessary carbs. Look for brands with simple ingredients and no added sugars.
• Italian seasoning: Creates that classic Italian restaurant profile with minimal effort. I recommend buying whole dried herbs and crushing them yourself for maximum aroma.
• Garlic cloves: Provides essential aromatic base. Select firm bulbs with tight skin for the freshest flavor.
• Olive oil: Carries flavors and provides authentic Mediterranean richness. Extra virgin offers the best flavor profile.
• Almond flour: Acts as a slight thickener while keeping the dish gluten-free and low-carb. Use blanched variety for the smoothest texture.
• Parmesan cheese: Delivers that distinctive sharp, nutty flavor essential to chicken parm. Always buy a block and grate it fresh.
• Mozzarella cheese: Creates that irresistible cheese pull and creamy mouthfeel. Fresh mozzarella can be too watery, so use low-moisture variety.
• Parmesan crisps or pork rinds: Cleverly replaces traditional breadcrumbs for the crispy topping. Crush them finely for even coverage.

Step-by-Step Instructions

Preheat Oven:

Set your oven to 350°F before beginning any prep work. This ensures the oven reaches the proper temperature by the time your casserole is assembled. The moderate heat allows for even cooking without burning the cheese topping.

Prepare Flavor Base:

Heat olive oil in a large skillet over medium heat until it shimmers slightly. Add minced garlic and sauté just until fragrant which usually takes about 60 seconds. Watch carefully as garlic burns quickly and becomes bitter. The garlic infuses the oil with essential flavor.

Build Sauce:

Add Italian seasoning directly to the garlic oil, allowing the heat to activate the dried herbs and release their essential oils. Pour in marinara sauce and sprinkle almond flour while stirring continuously to prevent lumping. The almond flour helps thicken the sauce slightly without adding carbs.

Combine With Chicken:

Add cubed chicken to the sauce mixture, folding gently to coat every piece thoroughly. Allow this mixture to simmer for 5 minutes which helps the flavors meld and ensures the sauce clings beautifully to the chicken pieces.

Assemble Casserole:

Spray a 9x13 inch casserole dish thoroughly with non-stick cooking spray, ensuring all corners are coated. Transfer the chicken mixture to the prepared dish, spreading it evenly to create a level base for the cheese layers.

Add Cheese Layers:

Sprinkle grated parmesan as the first cheese layer, distributing it evenly across the entire surface. Follow with an even layer of shredded mozzarella, being generous for that classic cheesy experience. Finally, add the crushed parmesan crisps or pork rinds as the top layer for a crispy finish.

Bake To Perfection:

Place the casserole on the middle rack of your preheated oven. Bake for 25-30 minutes until you see bubbling around the edges and the cheese has melted completely with light golden spots appearing on top. The edges will become slightly crisp while the center remains creamy.

Rest Before Serving:

Allow the casserole to rest for 5-7 minutes after removing from the oven. This crucial step allows the molten cheese to set slightly and the flavors to settle, making serving neater and enhancing the overall eating experience.

Save

The parmesan cheese is truly the star ingredient here. I discovered that using both grated parmesan in the cheese layer and crushed parmesan crisps on top creates an incredible depth of flavor that truly mimics the experience of traditional chicken parmesan without the carbs or gluten.

Make-Ahead Options

This casserole actually improves with time as the flavors meld together. You can prepare the entire dish up to the baking step, cover tightly with plastic wrap and refrigerate for up to 2 days. When ready to serve, simply remove from the refrigerator 30 minutes before baking to take the chill off, then bake as directed, adding about 10 minutes to the cooking time. The convenience factor makes this perfect for entertaining or busy weeknights when you need dinner ready with minimal fuss.

Substitution Ideas

This recipe offers excellent flexibility based on what you have available. Leftover holiday turkey works beautifully in place of chicken. For a dairy sensitivity, try dairy-free cheese alternatives though they will not melt quite the same as traditional cheese. Coconut flour can substitute for almond flour if needed, but use only one teaspoon as it absorbs more liquid. For the crispy topping, crushed keto-friendly crackers work wonderfully if you cannot find parmesan crisps or prefer not to use pork rinds.

Serving Suggestions

While this casserole stands perfectly as a complete meal on its own, pairing it with complementary sides elevates the dining experience. A simple arugula salad dressed with lemon and olive oil provides a peppery freshness that cuts through the richness. Roasted broccoli or zucchini noodles make excellent vegetable companions that maintain the low-carb profile. For those not strictly following keto, a good Italian red wine like Chianti completes the authentic Italian experience.
