Recipe Instructions
Step 1
Preheat the oven to 375 degrees F (190 degrees C). Lightly butter a 9x13-inch casserole dish.
Step 2
Melt 3 tablespoons butter in a medium saucepan over medium heat. Saute onion with 1/2 teaspoon kosher salt until it starts to soften up and turn translucent, 3 to 4 minutes. Add the flour, and cook, stirring, for 3 minutes, reducing heat if needed.
Step 3
Pour in cold milk and whisk for 1 minute. Raise heat to medium-high and cook, stirring often, until the sauce thickens and comes to a simmer. Remove from heat, whisk in Cheddar cheese, and reserve until needed.
Step 4
Fill a large pot with water and remaining salt and bring to a rapid boil. Cook egg noodles for 5 minutes. Drain well and add to a large mixing bowl. Stir in the reserved sauce, followed by tuna, peas, cayenne, black pepper, and Worcestershire sauce. Mix with a spatula until evenly combined.
Step 5
Pour the mixture into the prepared dish. Mix bread crumbs, Parmigiano-Reggiano cheese, and olive oil together in a small bowl until combined and resembling wet sand. Sprinkle evenly over the casserole.
Step 6
Bake in the center of the preheated oven until browned and bubbly, about 30 minutes. Let sit for 10 minutes before cutting and serving.
