Step-by-Step Cooking Instructions

1. Preheat the oven to 375°F (190°C).
   This helps the casserole bake evenly and develop a lightly golden top.
2. Sauté onion, garlic, carrots, and mushrooms in a large skillet over medium heat.
   Cook for about 6 minutes until vegetables soften and release flavor.
3. Add chicken broth and heavy cream to the skillet.
   Simmer for 3–4 minutes to create a creamy sauce.
4. Season with thyme, parsley, salt, and pepper.
   Stir well to distribute flavors.
5. Fold in cooked chicken, peas, pasta, and shredded cheese.
   Mix until everything is evenly coated in sauce.
6. Transfer mixture into a greased 9×13-inch baking dish.
   Spread evenly for uniform baking.
7. Sprinkle breadcrumbs evenly over the top.
   This adds a crisp layer after baking.
8. Bake uncovered for 25–30 minutes.
   The top should be golden and the sauce bubbling.
9. Cool completely if freezing or rest 5 minutes before serving.
   Cooling prevents freezer moisture buildup.
