Ingredients

• 250 grams pasta (penne, macaroni, or shells)
• 50 grams butter
• 50 grams all-purpose flour
• 500 milliliters milk
• 150 grams grated cheddar cheese
• 50 grams grated parmesan cheese
• 300 grams canned tuna in spring water, drained
• 100 grams frozen peas
• 100 grams sweet corn kernels
• 50 grams breadcrumbs
• 1 tablespoon olive oil or melted butter
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 1 teaspoon mustard (optional, for extra flavor)

Directions

Step 1

Preheat your oven to 190°C (375°F). Lightly grease a medium-sized baking dish and set aside.

Step 2

Cook the pasta in a large pot of salted boiling water according to the package instructions, until al dente. Drain and set aside.

Step 3

In a medium saucepan, melt the butter over medium heat. Add the flour and whisk constantly for 1–2 minutes until it forms a smooth paste and starts to bubble.

Step 4

Gradually add the milk, a little at a time, whisking continuously to avoid lumps. Cook for 3–5 minutes until the sauce thickens.

Step 5

Stir in 100g of grated cheddar cheese and all of the parmesan cheese until melted and smooth. Add the mustard (if using), salt, and black pepper, stirring to combine.

Step 6

Remove the sauce from heat and gently fold in the tuna, peas, corn, and cooked pasta until evenly combined.

Step 7

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

Step 8

In a small bowl, combine the breadcrumbs, remaining cheddar cheese, and olive oil or melted butter. Sprinkle this mixture evenly over the top of the casserole.

Step 9

Bake in the preheated oven for 20–25 minutes, or until the top is golden and crispy.

Step 10

Let the Tuna Mornay cool slightly for 5 minutes before serving.
