Ingredients

• 12 ounces pasta shells
• 4 tablespoons unsalted butter
• 1 medium yellow onion, finely chopped
• 3 cloves garlic, minced
• 3 tablespoons all-purpose flour
• 2 cups whole milk
• 1.5 cups chicken broth
• 1 teaspoon dijon mustard
• 2 cups white cheddar, shredded
• 2 cans (5 ounces each) canned tuna in water, drained
• 1 cup frozen peas
• 1 cup panko breadcrumbs
• 2 tablespoons olive oil
• 2 tablespoons parsley, chopped (optional)
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper

Directions

Step 1

Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with butter or nonstick cooking spray.

Step 2

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.

Step 3

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.

Step 4

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.

Step 5

Slowly whisk in the milk and chicken broth, ensuring no lumps remain. Continue to whisk until the mixture thickens, about 4-5 minutes.

Step 6

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.

Step 7

Fold the drained tuna and frozen peas into the cheese mixture, followed by the cooked pasta shells. Mix until everything is evenly coated.

Step 8

Transfer the mixture to the prepared baking dish and spread it out in an even layer.

Step 9

In a small bowl, mix the panko breadcrumbs with olive oil. Sprinkle the breadcrumbs evenly over the casserole for a crisp topping.

Step 10

Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and the topping is golden brown.

Step 11

Let the casserole cool for 5 minutes before serving. Garnish with chopped parsley if desired.
