Ingredients You’ll Need

Getting started on the Keto Chicken Parmesan Casserole is all about having simple, straightforward ingredients that each play an essential role. From the savory shredded chicken to the blend of cheeses and spices, every item contributes to the delicious layers of flavor, texture, and color that make this casserole truly special.

• 4 cups cubed rotisserie chicken: Using pre-cooked chicken saves time and adds incredible flavor and tenderness.
• 3/4 cup no added sugar marinara sauce: This keeps the dish low in carbs while delivering that classic tangy tomato taste.
• 1 tbsp Italian seasoning: A fragrant blend that perfectly complements the chicken and cheese.
• 2 garlic cloves (minced): Provides a punch of aromatic flavor that’s key to any great Italian-inspired recipe.
• 1 tbsp olive oil: For sautéing garlic and bringing richness to the sauce base.
• 2 tbsp almond flour: Adds a subtle nutty flavor and helps thicken the mix without adding carbs.
• 3/4 cup parmesan cheese (grated): Parmesan’s sharp, salty character amplifies the cheesy goodness inside and on top.
• 1 1/2 cups shredded mozzarella cheese: Melts beautifully, creating that irresistible gooey texture.
• 3/4 cup finely crushed parmesan crisps (or pork rinds): Topped on for a crunchy, golden finish that mimics traditional breadcrumbs.
• Non-stick cooking spray: Keeps the casserole from sticking and makes cleanup easier.

How to Make Keto Chicken Parmesan Casserole

Step 1: Prepare the Oven and Garlic

Begin by preheating your oven to 350°F, setting the perfect temperature for gentle baking. Then, heat the olive oil in a large skillet over medium heat and add the minced garlic. Let the garlic sauté for about one minute until it becomes fragrant and starts to turn golden—this small step builds a hugely flavorful foundation.

Step 2: Create the Chicken Mixture

Next, add the Italian seasoning, marinara sauce, and almond flour to the skillet. Stir everything together, then toss in your cubed chicken. Cook this mixture for about five minutes, allowing the almond flour to thicken the sauce slightly and the chicken to soak up all those delicious savory notes.

Step 3: Assemble the Casserole

Spray a 9” x 13” casserole dish with non-stick cooking spray to ensure easy serving later. Pour your chicken and sauce mixture evenly into the dish, spreading it out gently to form the base layer for your casserole.

Step 4: Add the Cheese Layers

Now comes the best part—the cheese! First, sprinkle the grated parmesan cheese evenly over the chicken mixture. Follow this with a generous layer of shredded mozzarella. Finally, top everything off with the finely crushed parmesan crisps or pork rinds for that irresistible crispy topping that’s oh-so-satisfying.

Step 5: Bake to Perfection

Place your assembled casserole into the oven and bake for 25 to 30 minutes. The best sign that it’s done? The casserole should be heated through, bubbling slightly at the edges, and the cheese on top melted to a golden, melty delight.

Step 6: Rest Before Serving

Once you take your Keto Chicken Parmesan Casserole out of the oven, let it sit for a few minutes. Resting allows the flavors to settle and gives the casserole a chance to firm up a little for easier slicing and serving. Then, dig in and enjoy!

How to Serve Keto Chicken Parmesan Casserole

Garnishes

Adding garnishes to your Keto Chicken Parmesan Casserole can elevate the dish immensely. Freshly chopped basil or parsley offers a pop of color and fresh aroma, while a light drizzle of olive oil or a sprinkle of crushed red pepper flakes can add depth and a touch of heat for those who love a little kick with their comfort food.

Side Dishes

Because this casserole is packed with protein and cheese, pairing it with a light, fresh side is ideal. Consider a crisp Caesar salad or some sautéed garlic green beans to balance the richness. Roasted vegetables like zucchini or asparagus also complement the casserole beautifully, keeping the meal vibrant and keto-friendly.

Creative Ways to Present

Want to impress your guests? Serve the casserole in individual ramekins for a personal touch. Or layer it in clear glass baking dishes so the beautiful layers of chicken, sauce, and cheese are visible—making it as visually enticing as it is delicious. You can even sprinkle a little extra fresh parmesan or herbs just before serving to give it a restaurant-quality finish.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers (and believe me, that’s a great problem to have), store the Keto Chicken Parmesan Casserole in an airtight container in the refrigerator. It will stay delicious for up to 3 days, perfect for quick lunches or dinners later in the week.

Freezing

This casserole also freezes exceptionally well. Wrap it tightly with plastic wrap and aluminum foil or use a freezer-safe container. When frozen, it can last up to 2 months without losing its flavor or texture, ready to be thawed and reheated whenever you need a quick, keto-friendly meal.

Reheating

To reheat, place a portion of Keto Chicken Parmesan Casserole in the oven at 350°F for about 15-20 minutes or until warmed through and the cheese is bubbling again. Microwaving works in a pinch but may soften the crispy topping, so an oven or toaster oven is best to preserve texture.

FAQs

Can I use fresh chicken instead of rotisserie chicken?

Absolutely! You can cook and cube fresh chicken breasts or thighs. Just be sure to cook them fully first before adding to the casserole to keep the texture and flavor just right.

Is parmesan crisps the only topping option?

Not at all! If you prefer, pork rinds crushed finely work perfectly as a low-carb alternative to breadcrumbs or crisps, offering similar crunch and flavor.

Can I make this recipe dairy-free?

While cheese is essential to this dish’s signature taste, you can try dairy-free cheese alternatives, but the texture and flavor won’t be quite the same. If dairy-free is a must, look for blends meant for melting and consider skipping the parmesan crisps topping.

How spicy is this casserole?

This casserole is mild and comforting by default, but you can easily add red pepper flakes or a pinch of cayenne while cooking to give it a gentle spicy kick.

Is this dish suitable for meal prepping?

Definitely! Keto Chicken Parmesan Casserole is perfect for meal prep. Make a big batch, portion it out, and store in the fridge or freezer for easy meals throughout the week.
