Ingredients

• 12 oz medium pasta shells
• 3 tbsp butter
• 3 tbsp all-purpose flour
• 2 cups milk
• 1.5 cups chicken or vegetable broth
• 2 cups sharp cheddar cheese, shredded
• 0.5 cups Parmesan cheese, grated
• 1 tsp garlic powder
• 1 tsp onion powder
• 1 tsp salt
• 0.5 tsp black pepper
• 2 cans (5 oz each) canned tuna, drained
• 1 cup frozen peas
• 1 cup panko breadcrumbs
• 2 tbsp olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish.

Step 2

Cook pasta shells in salted boiling water according to package instructions until al dente. Drain and set aside.

Step 3

In a medium saucepan, melt butter over medium heat. Add the flour and whisk to create a roux. Cook for 1-2 minutes, stirring constantly, until the mixture is lightly golden.

Step 4

Slowly pour in the milk and broth while whisking continuously to prevent lumps. Bring the mixture to a simmer and let it thicken, about 3-5 minutes.

Step 5

Remove the saucepan from heat and stir in shredded cheddar cheese, Parmesan cheese, garlic powder, onion powder, salt, and black pepper until cheese is fully melted and the sauce is smooth.

Step 6

In a large mixing bowl, combine the cooked pasta, creamy cheese sauce, drained tuna, and frozen peas. Mix gently to combine.

Step 7

Transfer the mixture into the prepared baking dish, spreading it out evenly.

Step 8

In a small bowl, mix panko breadcrumbs with olive oil. Sprinkle the breadcrumb mixture evenly over the casserole.

Step 9

Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and the casserole is bubbling around the edges.

Step 10

Remove the casserole from the oven and let it cool for 5 minutes before serving. Enjoy!
