Ingredients

• 250 grams elbow macaroni
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 2 cups milk
• 2 cups sharp cheddar cheese, shredded
• 2 cans (5 ounces each) canned tuna, drained
• 1 cup frozen peas
• 1 teaspoon onion powder
• 1 teaspoon garlic powder
• 0.5 teaspoon salt
• 0.5 teaspoon black pepper
• 1 cup breadcrumbs
• 0.25 cup Parmesan cheese, grated
• 1 tablespoon olive oil

Directions

Step 1

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

Step 2

Cook the elbow macaroni according to the package directions until al dente. Drain and set aside.

Step 3

In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to make a roux.

Step 4

Slowly pour in the milk while whisking continuously to prevent lumps. Cook for 3-4 minutes until the sauce thickens.

Step 5

Reduce heat to low and stir in the shredded cheddar cheese until it melts and forms a smooth sauce. Add the onion powder, garlic powder, salt, and black pepper. Mix well.

Step 6

In a large mixing bowl, combine the cooked macaroni, cheese sauce, drained tuna, and frozen peas. Mix until evenly combined.

Step 7

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

Step 8

In a small bowl, mix the breadcrumbs, grated Parmesan cheese, and olive oil. Sprinkle this breadcrumb mixture evenly over the top of the casserole.

Step 9

Bake in the preheated oven for 20-25 minutes, or until the topping is golden and crispy and the casserole is heated through.

Step 10

Remove the dish from the oven and let it cool for 5 minutes before serving. Enjoy your easy macaroni tuna bake!
