Ingredients

Main Ingredients

• 3 cups cooked chicken, shredded or diced
  (Rotisserie chicken works best)
• 2 cups cooked pasta or cooked rice
• 1 cup frozen peas, corn, or mixed vegetables
• 1 cup mushrooms, sliced (optional)
• 1 small onion, finely chopped
• 2 cloves garlic, minced

Creamy Sauce Ingredients

• 1 can (300 g / 10.5 oz) cream of chicken soup
• 1 cup sour cream or Greek yogurt
• ½ cup milk or chicken broth
• 1 teaspoon salt
• ½ teaspoon black pepper
• 1 teaspoon paprika
• ½ teaspoon dried thyme or Italian seasoning

Cheese & Topping

• 1½ cups shredded cheddar, mozzarella, or Monterey Jack cheese
• ½ cup grated Parmesan cheese
• 1 cup crushed crackers, cornflakes, or breadcrumbs
• 3 tablespoons melted butter

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 180°C (350°F). Grease a large baking dish (9×13 inches) with butter or cooking spray to prevent sticking.

Step 2: Prepare the Vegetables

1. Heat 1 tablespoon of oil or butter in a large skillet over medium heat.
2. Add the chopped onion and cook for about 4–5 minutes until soft and translucent.
3. Add the garlic and mushrooms (if using) and cook for another 2 minutes until fragrant.
4. Remove from heat and set aside.

This step builds flavor and prevents raw onion taste in the casserole.

Step 3: Make the Creamy Sauce

1. In a large mixing bowl, combine the cream of chicken soup, sour cream, and milk.
2. Whisk until smooth and creamy.
3. Add salt, pepper, paprika, and dried herbs.
4. Taste and adjust seasoning if needed.

Step 4: Combine Everything

1. Add the cooked chicken to the sauce.
2. Stir in the cooked pasta or rice.
3. Add the sautéed vegetables and frozen vegetables.
4. Mix gently until everything is evenly coated.
5. Fold in 1 cup of shredded cheese for extra creaminess.

Step 5: Assemble the Casserole

1. Transfer the mixture into the prepared baking dish.
2. Spread it evenly with a spatula.
3. Sprinkle the remaining shredded cheese and Parmesan evenly on top.

Step 6: Add the Crispy Topping

1. In a small bowl, mix crushed crackers or breadcrumbs with melted butter.
2. Sprinkle the mixture evenly over the cheese layer.

This topping gives the casserole its signature crunchy finish.

Step 7: Bake

1. Place the dish in the preheated oven.
2. Bake uncovered for 40–45 minutes, until the casserole is bubbling and the top is golden brown.
3. If the top browns too fast, loosely cover with foil for the last 10 minutes.

Step 8: Rest and Serve

Remove from the oven and let the casserole rest for 5–10 minutes before serving. This allows it to set and makes serving cleaner and easier.
