Ingredients

• 8 ounces macaroni pasta
• 2 cups broccoli florets
• 2 5-ounce cans canned tuna (drained)
• 3 tablespoons butter
• 3 tablespoons all-purpose flour
• 2 cups milk
• 2 cups sharp cheddar cheese (shredded)
• 1 cup Parmesan cheese (grated)
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.5 cup panko breadcrumbs
• 1 tablespoon olive oil or melted butter

Directions

Step 1

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

Step 2

Bring a large pot of salted water to a boil. Cook the macaroni according to the package instructions until al dente. In the last 2 minutes of cooking, add the broccoli florets to the boiling water with the pasta. Drain both and set aside.

Step 3

In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute until the mixture is smooth and bubbly.

Step 4

Slowly pour in the milk while whisking continuously. Cook the mixture for 3-5 minutes, or until it thickens.

Step 5

Reduce the heat to low and stir in the cheddar cheese and half of the Parmesan cheese. Stir until the cheese melts and the sauce is smooth.

Step 6

Season the cheese sauce with garlic powder, onion powder, salt, and black pepper. Remove the saucepan from the heat.

Step 7

In a large mixing bowl, combine the cooked macaroni, broccoli, drained tuna, and cheese sauce. Mix until everything is evenly coated.

Step 8

Transfer the mixture to the prepared baking dish and spread it out evenly.

Step 9

In a small bowl, mix the panko breadcrumbs with the olive oil or melted butter. Stir in the remaining Parmesan cheese and sprinkle the mixture over the casserole.

Step 10

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

Step 11

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