Step-by-Step Cooking Instructions

1. Preheat the air fryer to 350°F (175°C).
   Preheating ensures even cooking and helps the casserole start bubbling quickly once inside. Allow it to heat for about 3–5 minutes.
2. Mix the filling ingredients.
   In a medium bowl, combine diced chicken, heavy cream, sour cream, half of the mozzarella, cheddar cheese, vegetables, and all seasonings. Stir until evenly coated. This ensures every bite has balanced flavor.
3. Transfer to a small baking dish (6–7 inch dish).
   Lightly grease the dish and spread the mixture evenly. A small ceramic or metal dish that fits inside your air fryer basket works best.
4. Top with remaining mozzarella cheese.
   Sprinkle the rest of the cheese evenly over the surface. This layer creates the golden crust during cooking.
5. Air fry for 12–15 minutes.
   Place the dish in the basket and cook at 350°F. The casserole is ready when the top is melted, bubbly, and lightly golden.
6. Rest for 5 minutes before serving.
   Letting it sit allows the sauce to thicken slightly and makes serving easier.

Serving Suggestions

---

Serve this casserole straight from the baking dish for a cozy, family-style feel, or spoon individual portions onto warm plates for a more polished presentation.

Fresh chopped parsley or a light sprinkle of red pepper flakes adds color and brightness. You can also drizzle a touch of hot sauce for extra flavor.

Pair it with a crisp green salad, garlic bread, or roasted vegetables. For a lighter meal, serve it alongside steamed broccoli or zucchini. It works just as well for a casual weeknight dinner as it does for a relaxed weekend meal.

Meal Prep Tips

You can assemble the casserole up to 24 hours in advance and store it covered in the refrigerator before air frying.

Leftovers can be stored in an airtight container for up to 3 days. Reheat in the air fryer at 320°F (160°C) for 5–7 minutes to maintain texture.

After storage, the sauce may thicken slightly. Adding a tablespoon of milk before reheating helps restore creaminess.

Common Mistakes to Avoid

• Overfilling the dish
  Filling too high can cause uneven cooking. Keep the mixture level and below the rim.
• Skipping preheating
  Starting in a cold air fryer can lead to uneven melting and longer cook times.
• Using raw chicken
  This recipe works best with pre-cooked chicken. Raw chicken may not cook through evenly in this small format.
• Cooking at too high a temperature
  Higher heat can brown the cheese too quickly while leaving the center undercooked. Stick to 350°F.
• Not letting it rest
  Cutting into it immediately can make it runny. A short rest improves texture.
