Tuna Noodle Dump Dinner

This creamy tuna-noodle dump dinner is made entirely in one baking dish, egg noodles included. It tastes just like the casserole you grew up eating but requires less equipment (and cleanup). Instead of using the classic cream of mushroom soup, we opted for a combination of cheese, broth, heavy cream and sour cream, which provides the same velvety texture.

Nonstick cooking spray

2 1/2 cups low-sodium chicken broth 

3/4 cup heavy cream 

1/2 cup sour cream 

4 ounces cream cheese, at room temperature (about 1/2 cup) 

1 tablespoon Dijon mustard 

2 scallions, thinly sliced 

Kosher salt and freshly ground black pepper 

One 12-ounce bag wide egg noodles 

Two 5-ounce cans white albacore tuna, drained and flaked 

6 ounces cremini mushrooms, thinly sliced (about 2 cups) 

1 1/2 cups frozen peas, thawed 

8 ounces mild Cheddar, shredded (about 2 cups; preferably from a block and not pre-shredded) 


  1. Preheat the oven to 425 degrees F. Generously spray the bottom and sides of a 9-by-13-inch casserole dish with nonstick spray.
  2. Whisk the chicken broth, heavy cream, sour cream, cream cheese, mustard, scallions, 1 1/2 teaspoons salt and a few grinds of pepper in a large bowl until smooth and no lumps of cream cheese remain. 
  3. Spread half the noodles in an even layer in the bottom of the prepared dish. Scatter half of the tuna, mushrooms and peas over the pasta. Pour half of the broth mixture over the top, then sprinkle with 1 cup of the Cheddar. Repeat to make a second layer with the remaining noodles, tuna, mushrooms and peas. 
  4. Cover tightly with foil and bake until the noodles are al dente, about 40 minutes. Uncover and sprinkle the remaining 1 cup Cheddar evenly on top. Bake until the cheese has melted and the sauce has thickened slightly, 10 to 12 minutes. Let the casserole sit for about 10 minutes before serving.
