How to Make Easy Keto Chicken Parmesan Casserole
Step 1: Preheat and Prepare
Preheat your oven to 350 degrees Fahrenheit. This step is essential because you want your casserole to bake evenly. While it’s heating up, prepare a 9×13-inch casserole dish with nonstick cooking spray so nothing sticks!
Step 2: Combine Your Ingredients
In a large bowl, mix together your cooked chicken, half of the marinara sauce, one cup of parmesan cheese, and one cup of mozzarella cheese (or two cups if you’re feeling cheesy!). This combination creates the flavorful base for your casserole. Once mixed well, transfer everything into your prepared casserole dish.
Step 3: Layer It Up
Pour the remaining marinara sauce over the top of your chicken mixture. This layer not only adds moisture but also infuses every bite with delicious flavor. Then sprinkle on the rest of your mozzarella cheese followed by almond flour. The almond flour will give you that delightful crispy topping we all love.
Step 4: Bake It
Bake your casserole in the preheated oven for about 30 minutes or until you see that beautiful golden cheese bubbling away. The aroma will fill your kitchen and make everyone eager to dig in!
