Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with butter or nonstick cooking spray.
Bring a large pot of salted water to a boil and cook the pasta shells according to the package instructions until al dente. Drain and set aside.
In a large skillet, melt 4 tablespoons of unsalted butter over medium heat. Add the chopped onion and sauté for 3-4 minutes until softened. Add the minced garlic and cook for an additional minute.
Sprinkle the flour over the onions and garlic, stirring constantly to form a roux. Cook for 1-2 minutes to remove the raw flour taste.
Slowly whisk in the milk and chicken broth, ensuring no lumps remain. Continue to whisk until the mixture thickens, about 4-5 minutes.
Reduce the heat to low and stir in the Dijon mustard, shredded white cheddar, salt, and pepper. Mix until the cheese has melted into a smooth sauce.
Fold the drained tuna and frozen peas into the cheese mixture, followed by the cooked pasta shells. Mix until everything is evenly coated.
Transfer the mixture to the prepared baking dish and spread it out in an even layer.
In a small bowl, mix the panko breadcrumbs with olive oil. Sprinkle the breadcrumbs evenly over the casserole for a crisp topping.
Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and the topping is golden brown.
Let the casserole cool for 5 minutes before serving. Garnish with chopped parsley if desired.
