Recipe Information
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)
Instructions
Preheat your oven to 190°C (375°F). Lightly grease a medium-sized baking dish and set aside.
Cook the pasta in a large pot of salted boiling water according to the package instructions, until al dente. Drain and set aside.
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.
Gradually add the milk, a little at a time, whisking continuously to avoid lumps. Cook for 3–5 minutes until the sauce thickens.
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.
Remove the sauce from heat and gently fold in the tuna, peas, corn, and cooked pasta until evenly combined.
Transfer the mixture into the prepared baking dish and spread it out evenly.
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.
Bake in the preheated oven for 20–25 minutes, or until the top is golden and crispy.
Let the Tuna Mornay cool slightly for 5 minutes before serving.
