Preheat your oven to 180°C (350°F).
In a large saucepan over medium heat, melt the butter.
Once the butter is melted, add the flour and stir continuously for 1-2 minutes to form a smooth paste (roux).
Gradually add the milk, whisking constantly to ensure there are no lumps, until the mixture thickens into a smooth sauce.
Reduce the heat to low and stir in the grated cheddar cheese, grated parmesan cheese, dijon mustard, salt, and black pepper. Mix until the cheese is fully melted and the sauce is creamy.
Add the drained tuna, frozen peas, and cooked pasta to the cheese sauce. Stir gently to combine evenly.
Transfer the mixture to a greased baking dish, spreading it out evenly with a spatula.
In a small bowl, toss the breadcrumbs with olive oil. Sprinkle the breadcrumbs evenly over the top of the tuna mixture.
Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and the sauce is bubbling.
Allow the Tuna Mornay to cool for 5 minutes before serving. Enjoy!
