• Cutting board
• Chef’s knife
• Colander

Ingredients

• 12 oz wide egg noodles
• 2 tablespoons olive oil
• 1 large yellow onion, chopped
• 2 medium carrots, diced
• 2 celery stalks, diced
• 8 oz cremini mushrooms, sliced (optional)
• 6 tablespoons unsalted butter
• 1/2 cup all-purpose flour
• 4 cups low-sodium chicken broth, warmed
• 1 cup whole milk or heavy cream, warmed
• 1 teaspoon garlic powder
• 1 teaspoon dried thyme
• 1/2 teaspoon dried rosemary, crushed
• Salt and freshly ground black pepper to taste
• 3 cups cooked, shredded or cubed chicken (rotisserie chicken works well)
• 1 cup frozen peas
• 1 cup shredded sharp cheddar or Gruyère cheese
• 1/4 cup chopped fresh parsley
• For the Topping:
• 1 cup panko breadcrumbs
• 2 tablespoons melted unsalted butter
• 1/4 cup grated Parmesan cheese

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
2. Cook the egg noodles in a large pot of salted boiling water according to package directions, but undercook them by 2 minutes (they should be very al dente). Drain and set aside.
3. While the noodles cook, heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the onion, carrots, and celery. Sauté for 5-7 minutes, until softened. If using mushrooms, add them and cook for another 5 minutes until they release their liquid and begin to brown. Remove the vegetables from the skillet and set aside.
4. In the same skillet, melt the 6 tablespoons of butter over medium heat. Whisk in the flour and cook for 1 minute, stirring constantly, to form a blond roux. This cooks out the raw flour taste.
5. Gradually pour in the warmed chicken broth, whisking continuously to prevent lumps. Once the broth is incorporated, slowly whisk in the warmed milk or cream until the sauce is smooth.
6. Bring the sauce to a simmer and cook for 5-8 minutes, stirring occasionally, until it has thickened enough to coat the back of a spoon. Remove from heat.
7. Stir in the garlic powder, thyme, rosemary, shredded cheddar/Gruyère cheese, and fresh parsley. Season generously with salt and pepper to taste. Continue stirring until the cheese is fully melted.
8. In a large bowl, combine the cooked noodles, shredded chicken, sautéed vegetables, and frozen peas. Pour the cream sauce over the mixture and gently stir until everything is evenly coated.
9. Transfer the mixture to the prepared baking dish and spread it into an even layer.
10. In a small bowl, combine the panko breadcrumbs, melted butter, and Parmesan cheese. Toss to combine, then sprinkle evenly over the top of the casserole.
11. Bake, uncovered, for 25-30 minutes, or until the casserole is hot and bubbly and the topping is golden brown and crisp.
12. Remove from the oven and let the casserole rest for 10 minutes before serving. This allows it to set up slightly.

Expert Cooking Tips

• Undercook the Noodles: It’s crucial to cook the noodles al dente as they will continue to absorb liquid and cook further in the oven. This prevents a mushy casserole.
• Use a Rotisserie Chicken: For a major time-saver, use a pre-cooked rotisserie chicken. Simply shred the meat and you’re ready to go.
• Warm Your Liquids: Warming the broth and milk before adding them to the roux helps create a smoother, lump-free sauce.
• Taste the Sauce: Before combining everything, taste your sauce and adjust the seasonings. It should be slightly more seasoned than you think necessary, as the noodles and chicken will absorb some of the flavor.

Substitutions and Variations

Feel free to customize this casserole to your liking. Swap the peas for steamed broccoli florets or green beans. Use cooked turkey instead of chicken, which is perfect for using up holiday leftovers. For the pasta, any short shape like penne, rotini, or shells will work just as well as egg noodles. For a different flavor profile, try a mix of cheeses like Monterey Jack and white cheddar.

Common Mistakes to Avoid

The most common mistake is creating a lumpy sauce. To avoid this, add your warmed liquids to the butter-flour roux very slowly at first, whisking vigorously and constantly until smooth before adding the rest. Another pitfall is a dry casserole; ensure your sauce is plentiful and creamy, as the noodles will absorb a significant amount of moisture during baking. If the sauce seems too thick, you can thin it with a little more milk or broth.

Serving Suggestions

This is a hearty, all-in-one meal, but it pairs beautifully with a simple side to cut through the richness. Serve with a crisp green salad tossed in a lemon vinaigrette, roasted asparagus, or garlic-steamed green beans. For a heartier meal, a side of crusty bread for dipping into the creamy sauce is always a welcome addition.

Storage and Reheating Tips

Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. To reheat, you can microwave individual portions or cover the entire baking dish with foil and heat in a 350°F (175°C) oven for 20-25 minutes, or until warmed through. The casserole also freezes exceptionally well.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, this is a great make-ahead meal. Assemble the entire casserole but leave off the breadcrumb topping. Cover tightly with plastic wrap or foil and refrigerate for up to 2 days. When you’re ready to bake, remove it from the fridge for 30 minutes, add the topping, and bake as directed, adding 10-15 minutes to the total time.

How do I freeze this chicken noodle casserole?

To freeze, assemble the casserole in a freezer-safe baking dish but do not add the breadcrumb topping. Allow it to cool completely, then cover tightly with a layer of plastic wrap followed by a layer of aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before adding the fresh topping and baking.

My sauce seems thin. What should I do?

If your sauce is too thin, simply let it simmer on the stove for a few more minutes, stirring occasionally. The heat will continue to reduce and thicken it. Remember that it will also thicken further as the cheese melts in and as it cools slightly.
