French Onion Chicken Noodle Casserole
This creamy and crunchy casserole brings together the flavors and textures of two soup favorites—French onion and chicken noodle.
Equipment
- 1 Large Skillet For caramelizing onions
- 1 Large Pot For cooking egg noodles
- 1 Colander For draining noodles
- 1 2-Quart Baking Dish For assembling and baking the casserole
- 1 Microwave-Safe Bowl For melting butter for the topping
Ingredients
Main
- 8 tablespoons 1 stick unsalted butter
- 3 large yellow onions thinly sliced
- Kosher salt and freshly ground black pepper
- 2 tablespoons fresh thyme leaves
- 6 ounces wide egg noodles
- 1/2 cup sour cream
- One 8-ounce package cream cheese at room temperature, cut into chunks
- 1 cup grated Gruyere cheese
- 2 cups shredded skinless rotisserie chicken
- 1 cup crispy fried onions such as French's
- 1/2 cup plain breadcrumbs
Instructions
- Preheat the oven to 350 degrees F.
- Melt 3 tablespoons butter in a large skillet over medium-high heat. Add the onions and sprinkle with 1 teaspoon salt and 1/2 teaspoon pepper and cook, stirring occasionally, until the onions are very soft and just begin to brown, about 20 minutes. Add 1 tablespoon thyme and cook for an additional minute. Set aside.
- Meanwhile, bring a large pot of salted water to a boil. Cook the noodles according to the package directions. Reserve 1/2 cup of the pasta water. Drain the noodles and return them to the pot.
- While the noodles are still warm, add the cooked onions, sour cream, cream cheese, reserved pasta water and 1/2 cup Gruyere. Stir until the sauce is smooth and creamy and coats the noodles. Fold in the chicken. Season with salt and pepper. Transfer to a 2-quart baking dish.
- Microwave the remaining 5 tablespoons butter in a medium microwave-safe bowl until melted. Add the fried onions, breadcrumbs, remaining 1/2 cup Gruyere and 1 tablespoon thyme to the butter and toss until the breadcrumbs are coated. Sprinkle the buttered breadcrumb mixture evenly over the noodles to cover completely.
- Bake until the topping is golden brown, 35 to 40 minutes.
Notes
Achieving deep flavor for the onions requires patient caramelization; cook them slowly until richly golden and sweet. Ensure egg noodles are cooked al dente, as they will continue to absorb liquid and soften in the oven. Room temperature cream cheese is crucial for a smooth, homogenous sauce. For the topping, thorough coating of the fried onions and breadcrumbs with butter is key to a uniformly crisp, golden-brown crust. A brief rest after baking allows the casserole to set beautifully.
