From-Scratch Tuna Noodle Casserole (Best Version)

1. 1

   Preheat the oven to 350 degrees F (175 degrees C). Lightly grease an ovenproof skillet and an 8x12-inch casserole dish.

2. 2

   Place the tuna in the prepared skillet and bake in the preheated oven until it flakes easily with a fork, 8 to 10 minutes.

3. 3

   Fill a large saucepan with lightly salted water and bring it to a rolling boil. Cook the fettuccine at a boil until tender yet firm to the bite, about 8 minutes. Drain and set aside.

4. 4

   Remove the tuna from the oven; keep the oven on.

5. 5

   Meanwhile, melt 3 tablespoons butter in a saucepan over medium heat. Cook the onion and mushrooms, stirring occasionally, until softened, 5 to 7 minutes. Stir in the flour until combined. Add the milk, bouillon concentrate, adobo seasoning, and black pepper. Cook, stirring constantly, until slightly thickened, about 5 minutes more. Remove the sauce from the heat and stir in the Parmesan cheese.

6. 6

   Put the remaining butter in a medium microwave-safe bowl and microwave until melted, about 30 seconds. Stir the bread crumbs into the melted butter and set aside.

7. 7

   Add the cooked fettuccine and flaked tuna to the cheese sauce and toss to combine. Transfer the noodle mixture to the prepared casserole dish and top with the torn bread.

8. 8

   Bake in the hot oven until golden brown, about 20 minutes.
