Step-by-Step Instructions

Cook the Chicken

1. Preheat your oven to 375°F and grease a casserole dish.
2. Heat olive oil in a skillet over medium heat.
3. Season chicken pieces with garlic powder, Italian seasoning, salt, and black pepper.
4. Cook the chicken for 6 to 8 minutes until lightly golden and fully cooked.
5. Remove from heat and set aside.

The chicken should remain juicy while absorbing the savory seasonings.

Assemble and Bake the Casserole

1. Spread softened cream cheese across the bottom of the prepared casserole dish.
2. Layer cooked chicken evenly over the cream cheese.
3. Pour marinara sauce over the chicken.
4. Sprinkle mozzarella cheese and Parmesan cheese evenly on top.

6. Garnish with fresh basil before serving.

You Must Know Before Baking

Use low-sugar marinara sauce to keep the casserole lower in carbs. Many store-bought sauces contain added sugars that increase carbohydrate content quickly.

Full-fat cream cheese creates the richest texture and helps balance the acidity of the tomato sauce.

Do not overcook the chicken before baking because it continues cooking in the oven. Slightly undercooked chicken in the skillet helps maintain tenderness after baking.

You can customize the casserole with vegetables like spinach, mushrooms, zucchini, or roasted peppers for additional texture and flavor.

This Keto Chicken Parmesan Casserole works perfectly for meal prep because the casserole reheats well while staying creamy and satisfying.

Reheat portions in the microwave or oven until heated through.

Allow frozen casserole portions to thaw overnight before reheating for the best texture.

Ingredient Substitutions

Replace chicken breast with chicken thighs for a richer flavor.
