Keto Chicken Parmesan Casserole Ingredients
For the Casserole
• Cubed Rotisserie Chicken or Chicken Breast – Use cooked and cubed chicken for convenience and to save time.
• No Added Sugar Marinara Sauce – Adds moisture and a rich tomato flavor; consider homemade for a fresher taste.
• Italian Seasoning – This blend of herbs enhances flavor, whether you opt for store-bought or homemade.
• Garlic (Minced) – Fresh garlic offers a pungent, aromatic note that elevates the dish.
• Olive Oil – Ideal for sautéing garlic and creating a rich texture; avocado oil is a great alternative too.
• Almond Flour – Helps hold the casserole together; substitute with coconut flour, but use less as it absorbs more moisture.
• Grated Parmesan Cheese – Adds a salty, cheesy flavor and ensures nice browning; freshly grated is best for meltability.
• Shredded Mozzarella Cheese – Provides that gooey, melty texture; whole milk mozzarella offers extra creaminess.
For the Topping
• Finely Crushed Parmesan Crisps or Pork Rinds – Gives a crispy topping; pork rinds are budget-friendly and keto suitable.
• Non-Stick Cooking Spray – Prevents sticking during baking; grease your dish with olive oil as an alternative.

Step‑by‑Step Instructions for Keto Chicken Parmesan Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This step is crucial as it ensures that your Keto Chicken Parmesan Casserole bakes evenly and thoroughly. While your oven is heating up, you can prep your other ingredients, making the process smooth and efficient.
Step 2: Sauté the Garlic
In a large skillet over medium heat, add a splash of olive oil. Once the oil is warm, add the minced garlic and sauté for about 1 minute until it becomes fragrant but not browned. This will infuse your dish with rich flavors, setting a delicious foundation for the casserole.
Step 3: Combine the Mixture
Next, add the Italian seasoning, no added sugar marinara sauce, almond flour, and cubed rotisserie chicken to the skillet. Stir everything together and let it cook for about 5 minutes. This melds the flavors beautifully and helps the chicken absorb the aromatic herbs and sauce.
Step 4: Transfer to Casserole Dish
After the mixture has cooked, carefully transfer it into a greased 9” x 13” casserole dish. Make sure to spread it evenly across the bottom of the dish to ensure that each serving has a great balance of flavors in this Keto Chicken Parmesan Casserole.
Step 5: Add the Cheese Layer
Now, layer the grated Parmesan cheese and shredded mozzarella cheese generously over the chicken mixture. This cheesy layer is what brings that classic comfort food feel to your casserole, so don’t be shy here!
Step 6: Prepare the Topping
Sprinkle finely crushed Parmesan crisps or pork rinds over the top of the cheese layer. This will create a crispy topping that contrasts beautifully with the creamy filling. Aim for an even distribution to ensure every bite is just as flavorful.
Step 7: Bake to Perfection
Place the casserole in the preheated oven and bake for 25-30 minutes. Keep an eye on it until the cheese is melted, bubbly, and golden brown on top. This visual cue indicates your Keto Chicken Parmesan Casserole is ready to be taken out of the oven.
Step 8: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. This resting time allows the layers to set, making serving easier and enhancing the overall texture. Scoop out portions and savor your homemade low-carb delight.

Expert Tips for Keto Chicken Parmesan Casserole
-
Use Warm Chicken: Ensure the cubed chicken is warmed through before mixing; it improves texture and helps flavors meld better in your Keto Chicken Parmesan Casserole.

Fresh Garlic is Key: Opt for fresh minced garlic rather than pre-packaged; it brings out the best aromatic flavor that elevates your casserole’s taste.
