Preheat oven to 375°F (190°C) and grease a 9x13-inch baking dish.
Cook the spaghetti according to package instructions until al dente. Drain and set aside.
In a large skillet, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until lightly golden to form a roux.
Gradually pour in the chicken broth while whisking constantly to prevent lumps. Add the heavy cream and bring the mixture to a gentle simmer.
Add the cream cheese and stir until completely melted and smooth. Stir in the Parmesan cheese, salt, pepper, and Italian seasoning.
Fold in the tuna, frozen peas, and cooked spaghetti to evenly coat with the creamy sauce.
Transfer the mixture to the prepared baking dish and spread it out evenly. Sprinkle the mozzarella cheese over the top.
In a small bowl, mix the breadcrumbs with olive oil. Sprinkle the breadcrumb mixture evenly over the mozzarella layer.
Bake in the preheated oven for 20-25 minutes or until the top is golden and bubbly.
Remove from the oven and let cool for 5 minutes before serving. Enjoy your Creamy Cheesy Easy Tuna Tetrazzini!
