Ingredients

• 60 grams butter
• 60 grams plain flour
• 500 milliliters milk
• 250 milliliters chicken stock
• 150 grams cheddar cheese, grated
• 425 grams tinned tuna in spring water, drained
• 300 grams corn kernels, drained
• 150 grams frozen peas
• 300 grams pasta shells or spirals, cooked
• 1 cup breadcrumbs
• 50 grams parmesan cheese, grated
• 1 teaspoon salt
• 0.5 teaspoon black pepper, freshly ground
• 2 tablespoons parsley, chopped (optional)

Directions

Step 1

Preheat your oven to 180°C (356°F).

Step 2

Melt the butter in a medium-sized saucepan over medium heat. Once melted, add the plain flour and whisk constantly for 1-2 minutes to create a roux. The mixture should form a smooth paste.

Step 3

Gradually add the milk and chicken stock to the roux, whisking continuously to avoid lumps. Cook for 5-7 minutes until the sauce thickens and coats the back of a spoon.

Step 4

Reduce the heat to low and stir in the cheddar cheese until melted and smooth. Add salt and black pepper to season the sauce.

Step 5

In a large mixing bowl, combine the cooked pasta, drained tuna, corn kernels, frozen peas, and the cheese sauce. Mix thoroughly so all ingredients are evenly coated in the sauce.

Step 6

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

Step 7

In a small bowl, combine the breadcrumbs, parmesan cheese, and chopped parsley (if using). Sprinkle this mixture evenly over the top of the tuna mornay.

Step 8

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

Step 9

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

Step 10

Garnish with additional parsley if desired and serve warm.
