How to Make Keto Chicken Parmesan Casserole
Step 1: Preheat Your Oven
Before you start cooking, preheat your oven to 350 F. This ensures that your casserole bakes evenly once it’s ready!
Step 2: Sauté Garlic
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté until fragrant, about 1 minute. This step is important as it brings out the garlic’s rich flavors, making your casserole more aromatic.
Step 3: Combine Ingredients
Add Italian seasoning, marinara sauce, almond flour, and chicken to the skillet. Stir everything together and let it cook for about 5 minutes. This allows the flavors to meld beautifully while keeping everything nice and moist.
Step 4: Assemble Your Casserole
Pour the chicken mixture into a 9” x 13” casserole dish that has been sprayed with non-stick cooking spray. Spreading everything evenly helps ensure every bite is packed with flavor.
Step 5: Layer on Cheese
Next, layer on the parmesan cheese followed by mozzarella cheese and finely crushed parmesan crisps. These layers create that delicious cheesy crust we all love!
Step 6: Bake
Pop your casserole into the oven and bake for 25-30 minutes until it’s heated throughout and bubbly on top. The melted cheese adds an irresistible touch.
Step 7: Cool Before Serving
Once done baking, remove the casserole from the oven and let it cool for a few minutes before serving. This little pause helps set everything perfectly so you can serve up warm portions without any mess.
Now you’re all set to enjoy this Keto Chicken Parmesan Casserole! It’s genuine comfort food that’s sure to become a staple in your kitchen.
