How to cook deliciously - Cheesy Chicken and Squash Casserole

1 . Stage

Preheat the oven to 350 degrees F (175 degrees C). Grease a 2 1/2-quart baking dish and set aside.

2 . Stage

Bring about 5 cups of lightly salted water to a boil in a large saucepan or Dutch oven. Add squash, onion, parsley, thyme, and bay leaf. Bring back to a boil and cook over medium heat until squash is fork-tender, 3 to 5 minutes. Drain and discard parsley sprigs and bay leaf. Lightly press squash to remove additional liquid, then set aside.

3 . Stage

Wipe out the saucepan and return to the heat. Melt 4 tablespoons butter over medium heat. Sprinkle in flour and stir, working out any lumps, until flour and butter start to bubble, about 2 minutes. Gradually stir in milk and heat to a boil, constantly stirring. Cook and stir until sauce thickens, 4 to 5 minutes.

4 . Stage

Remove sauce from heat and stir in seasoned salt, Worcestershire sauce, and nutmeg. Drizzle 2 tablespoons into egg yolks, constantly stirring to avoid lumps. Repeat with 2 additional tablespoons. Drizzle warmed eggs slowly back into the saucepan and stir until sauce is smooth. Stir in 1/2 of the Gruyère cheese and cayenne pepper. Season with salt and pepper.

5 . Stage

Place well-drained squash and onion into the prepared baking dish. Top with chicken. Pour sauce over chicken and squash and stir gently to coat.

6 . Stage

Combine 2 teaspoons butter, remaining Gruyère cheese, and bread crumbs for topping. Spread evenly over casserole.

7 . Stage

Bake in the preheated oven until the top is browned and bubbly, about 35 minutes. Allow cooling for 10 minutes before serving. Garnish with chopped parsley.
