Step‑by‑Step Instructions for Keto Chicken Parmesan Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial as it ensures your Keto Chicken Parmesan Casserole cooks evenly and helps achieve that deliciously golden-brown topping. While the oven heats, you can prepare the ingredients to streamline your cooking process.

Step 2: Sauté the Garlic
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Once the oil is shimmering, add 3 cloves of minced garlic and sauté for about 1 minute until fragrant. Be careful not to let the garlic brown, as burnt garlic can impart a bitter flavor to your casserole.

Step 3: Combine Ingredients
To the skillet, add Italian seasoning, 1 cup of no added sugar marinara sauce, 1/4 cup of almond flour, and the cubed rotisserie chicken. Stir together and let the mixture cook for about 5 minutes, allowing the flavors to meld and the chicken to heat through. You want a warm and cohesive mixture ready for the next step.

Step 4: Transfer to Casserole Dish
Pour the chicken mixture into a greased 9″x13″ casserole dish, spreading it evenly across the bottom. The greased surface helps prevent sticking, ensuring everything comes out smoothly. Take a moment to appreciate the vibrant colors of the sauce and chicken before moving on to the layering.

Step 5: Add the Cheese
Sprinkle a generous layer of grated Parmesan cheese and shredded mozzarella cheese over the chicken mixture, evenly distributing them for maximum cheesy goodness. As the casserole bakes, the cheese will melt beautifully, forming a gooey and mouthwatering top that is simply irresistible.

Step 6: Top with Crunch
Finish by adding the crushed Parmesan crisps or pork rinds on top for that perfect crunchy texture. This layer not only adds flavor but also an appealing visual aspect to your Keto Chicken Parmesan Casserole as it browns in the oven.

Step 7: Bake the Casserole
Place the casserole dish in the preheated oven and bake for 25-30 minutes. You will know it’s ready when the cheese is melted, bubbling, and has reached a golden-brown color. The aroma wafting from the oven will surely make your mouth water!

Step 8: Cool and Serve
Once baked, carefully remove the casserole from the oven and let it cool for a few minutes before serving. This resting time helps the layers set, making it easier to scoop out portions. Serve hot and enjoy the delightful flavors of your Keto Chicken Parmesan Casserole!

Keto Chicken Parmesan Casserole Recipe FAQs

How do I choose the right rotisserie chicken?
Absolutely! When picking a rotisserie chicken, look for one with moist, tender meat and a skin that’s golden-brown, avoiding any with dark spots or a dry appearance. Opt for chickens that have been freshly cooked—these often have the best flavor and texture for your casserole.

How long can I store leftover Keto Chicken Parmesan Casserole in the fridge?
Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Just be sure to let it cool completely before placing it in the container. When you’re ready to enjoy it again, I recommend reheating it in the oven to maintain that lovely, gooey texture!

Can I freeze Keto Chicken Parmesan Casserole?
Absolutely! To freeze, allow the casserole to cool completely and then portion it into freezer-safe containers. It can be frozen for up to 2 months. When you’re ready to eat, simply thaw it overnight in the fridge and then reheat in the oven at 350°F (175°C) for about 20-25 minutes until warmed through.

What should I do if my casserole is too dry?
If you find your Keto Chicken Parmesan Casserole is slightly dry after baking, it can often be salvaged! Try adding a splash of extra marinara sauce or a drizzle of olive oil while reheating. Covering it with foil can help retain moisture while it heats up in the oven.

Is this casserole suitable for people with nut allergies?
Yes, it can be! To make it nut-free, simply substitute almond flour with coconut flour, though you may need to adjust the quantity—generally, use about half the amount since coconut flour absorbs more moisture. Always double-check that your chosen marinara sauce does not contain any hidden allergens.

Can I add vegetables to the casserole?
Very! Feel free to include sautéed vegetables like bell peppers, spinach, or zucchini for added nutrition and flavor. Just make sure to drain any excess moisture before mixing them in to prevent the casserole from becoming watery.
