Ingredients

• 3 cups Cooked brown rice
• 2 5-ounce cans Canned tuna (in water, drained)
• 1 cup Frozen peas
• 4 tablespoons Unsalted butter
• 3 tablespoons All-purpose flour
• 2 cups Milk
• 1.5 cups Shredded cheddar cheese
• 1 teaspoon Garlic powder
• 1 teaspoon Onion powder
• 0.5 teaspoon Salt
• 0.25 teaspoon Ground black pepper
• 0.25 cup Grated Parmesan cheese
• 0.5 cup Breadcrumbs
• 0 Cooking spray

Directions

Step 1

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

Step 2

In a medium-sized saucepan, melt the butter over medium heat.

Step 3

Once melted, whisk in the flour and cook for about 1 minute, stirring constantly, to form a roux.

Step 4

Slowly pour in the milk while whisking continuously to ensure no lumps form. Cook for 4-5 minutes, or until the mixture thickens into a creamy sauce.

Step 5

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

Step 6

In a large mixing bowl, combine the cooked brown rice, drained tuna, frozen peas (no need to thaw), and the cheese sauce. Stir until all the ingredients are evenly combined.

Step 7

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

Step 8

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

Step 9

Place the casserole in the preheated oven and bake for 25-30 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 rest for 5 minutes before serving. Enjoy!
