Ingredients
-
1/2 pound fresh asparagus, trimmed and cut into pieces
-
1/4 cup butter
-
1 (8-ounce) package sliced fresh mushrooms
-
1/2 cup diced onion
-
1/4 cup all-purpose flour
-
3 cups chicken broth
-
1 (8-ounce) carton whipping cream
-
1/2 cup shredded Parmesan cheese, divided
-
1 teaspoon salt
-
1/2 teaspoon ground black pepper
-
2 handfuls baby spinach leaves
-
2 green onions, green parts only, sliced
-
2 1/2 cups chopped cooked chicken (rotisserie works great!)
-
1 (8-ounce) package medium egg noodles, cooked
Instructions
-
Preheat oven to 350°F and grease a 9×13-inch baking dish.
-
In a large skillet, melt the butter over medium heat. Add mushrooms and diced onion. Sauté for 5 minutes.
-
Stir in asparagus and cook for another 3 minutes.
-
Sprinkle flour over vegetables and stir to coat. Slowly whisk in chicken broth, then add whipping cream. Bring to a gentle simmer.
-
Stir in salt, pepper, and half the Parmesan. Cook until thickened, about 3–5 minutes.

Add spinach, green onions, chicken, and cooked noodles. Mix gently until everything is coated and spinach begins to wilt.
-
Pour into the prepared baking dish and sprinkle remaining Parmesan on top.
-
Bake uncovered for 20–25 minutes until bubbly and golden on top.
-
Let rest for 5 minutes before serving.
Notes
You can substitute frozen asparagus (thawed and drained) if fresh isn’t available.
Add crushed crackers or breadcrumbs on top for a crispy finish.
Make ahead: Assemble the casserole a day in advance and refrigerate until ready to bake.
