How to Make Parmesan Chicken Casserole Recipe
Step 1: Preheat the Oven
Preheat your oven to 375 degrees F. Gather all your ingredients and make sure everything is ready to go.
Step 2: Prepare the Egg Mixture
In a shallow bowl, whisk the egg until it’s well beaten.
Step 3: Combine Dry Ingredients
In another shallow bowl or a gallon-sized plastic bag, mix together almond flour, parmesan cheese, garlic salt, Italian seasoning, and pepper.
Step 4: Coat the Chicken
Dredge each piece of chicken in the egg mixture first. Then dip both sides into the dry coating mix. Set aside on a plate.
Step 5: Sear the Chicken
Heat olive oil in an ovenproof skillet over medium-high heat. Once hot, add each chicken piece and sear for about 4 minutes until golden brown. Ensure your pan is hot enough to make the chicken sizzle.
Step 6: Flip and Finish Searing
Turn each piece of chicken over and sear for an additional 3 minutes until both sides are nice and crispy.
Step 7: Set Aside Chicken
Remove the chicken from the skillet and place it on a cutting board. Let it rest for a moment.
Step 8: Sauté Spinach
Lower heat to medium. Add spinach to the same skillet and sauté until wilted, which should take about 1 to 2 minutes. Turn off heat once done.
Step 9: Cut Chicken Into Pieces
Carefully cut the seared chicken into bite-sized pieces while still warm.
Step 10: Combine Ingredients in Skillet
Return cut chicken back to the skillet. Stir in marinara sauce, ricotta cheese, and half of the mozzarella cheese. Mix well and top with remaining mozzarella cheese.
Step 11: Bake Casserole
Place in preheated oven at 375 degrees F for about 20 to 22 minutes or until cheese is bubbly and chicken is thoroughly cooked.
Now you have a delicious Parmesan Chicken Casserole ready to serve! Enjoy it as part of your next family meal or dinner gathering!

Common Mistakes to Avoid
When making your Parmesan Chicken Casserole Recipe, avoiding common pitfalls can help you achieve the best results. Here are some mistakes to watch out for:
- Skipping the searing step: Searing the chicken is crucial for flavor and texture. Don’t skip this; it locks in moisture and creates a delicious crust.
- Not measuring ingredients accurately: Precision matters in cooking. Use measuring cups and spoons to ensure your almond flour and cheese ratios are spot on.
- Ignoring the oven temperature: Cooking at the wrong temperature can lead to uneven cooking. Always preheat your oven to 375 degrees F before baking.
- Overcooking the chicken: Overcooked chicken can become dry. Keep an eye on the cooking time and use a meat thermometer if needed; chicken should reach an internal temperature of 165 degrees F.
- Using low-quality marinara sauce: The sauce contributes significantly to flavor. Opt for a low-carb marinara with no added sugar for the best taste.
