Step‑by‑Step Instructions for Keto Chicken Parmesan Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This essential first step ensures that your Keto Chicken Parmesan Casserole cooks evenly and thoroughly, resulting in tender chicken and bubbling cheese. Make sure your rack is set to the center position for optimal heat distribution, so your casserole turns out perfectly golden.

Step 2: Season the Chicken
While the oven is heating, take your boneless, skinless chicken breasts and season them generously with salt, pepper, Italian seasoning, and garlic powder. Use your hands to rub the seasoning into the meat, giving it a vibrant flavor profile that’s crucial for this Keto Chicken Parmesan Casserole. Set the chicken aside to allow the flavors to meld while you prepare the next steps.

Step 3: Arrange the Chicken in the Casserole Dish
Grab a medium-sized casserole dish and layer the seasoned chicken breasts in the bottom. Ensure they’re spread out evenly to allow for even cooking and maximum flavor absorption. You want to create a sturdy base for your casserole that will hold up to the rich marinara sauce you’re about to add, so make sure they fit snugly without crowding.

Step 4: Add the Marinara Sauce
Next, pour the sugar-free marinara sauce evenly over the chicken, making sure each piece is well-coated. The sauce will serve as the heart of your Keto Chicken Parmesan Casserole, adding moisture and depth to the dish. Use a spatula to gently spread the sauce if needed, creating a beautiful pool of rich flavor over the chicken.

Step 5: Sprinkle the Cheeses
Now, it’s time to generously sprinkle mozzarella and Parmesan cheeses over the marinara sauce. This cheesy layer is what will give your casserole that ooey-gooey texture and delightful golden crust once baked. Don’t hold back on the cheese—it’s one of the defining aspects of a delicious chicken parmesan.

Step 6: Cover with Foil
To retain moisture during baking, cover the casserole dish tightly with aluminum foil. This step is crucial for ensuring that the chicken cooks thoroughly while the cheese melts without browning too quickly. The steam created will help keep the chicken juicy and tender, setting up your Keto Chicken Parmesan Casserole for success.

Step 7: Bake the Casserole
Place your covered casserole dish in the preheated oven and bake for 30-40 minutes. Keep an eye on it; the chicken should reach an internal temperature of 165°F (74°C), ensuring it’s fully cooked. You’ll know it’s ready when you see bubbly sauce and melted cheese peeking through the foil edges.

Step 8: Uncover and Brown the Cheese
After the initial baking time, carefully remove the foil to let the top brown. Return the casserole to the oven for an additional 5-10 minutes. This step will give your Keto Chicken Parmesan Casserole that lovely golden color on top, enhancing both its visual appeal and texture.

Step 9: Let it Rest
Once the cheese is perfectly browned, take the casserole out of the oven and let it cool for a few minutes. This resting time allows the juices to redistribute, making it easier to serve and ensuring every bite is packed with flavor. Consider garnishing with fresh basil for an added touch of freshness.

How to Store and Freeze Keto Chicken Parmesan Casserole
