Delicious Tuna Noodle Casserole - cooking recipe

Ingredients

10 tablespoons butter
salt
4 1/2 cups flat egg noodles
5 scallions, chopped
3 tablespoons flour
1 1/2 teaspoons dry mustard
3 1/3 cups milk
fresh ground black pepper
1 (12 ounce) can tuna in vegetable oil, drained and broken into small chunks (packed in oil)
1 1/2 cups homemade fresh breadcrumbs

Preparation

Preheat oven to 375 degrees.
Rub inside of a 2 1/2 quart casserole dish with 1 tablespoons butter.
Bring large pot of salted water to boil over high heat.
Add noodles and cook until al dente, 5-7 minutes. Drain and transfer noodles to a large bowl.
Melt 4 tablespoons butter in a medium saucepan over medium-high heat.
Add half the scallions and cook until softened, 1-2 minutes.
Add flour and mustard and cook, stirring frequently, for 1 minutes.
Gradually pour in milk, whisking constantly, and bring to a boil.
Cook sauce, stirring frequently, until smooth and thickened, 16-18 minutes.
Season with salt and pepper to taste.
Transfer sauce to bowl with noodles.
Add tuna and stir gently to combine.
Transfer tuna-noodle mixture to prepared dish.
Melt remaining butter and toss with remaining scallions, bread crumbs, and salt and pepper to taste in a bowl.
Scatter seasoned bread crumbs over tuna-noodle mixture and bake until golden brown and bubbling, 20-25 minutes.
Let casserole cool slightly before serving.
