Scale
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 2 cups milk (whole or 2%)
- 1 cup grated cheddar cheese (plus extra for topping)
- 1 teaspoon Dijon mustard
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon garlic powder
- 1/4 cup frozen peas (optional)
- 1/4 cup sweetcorn kernels (optional)
- 2 cans (185g each) tuna in spring water, drained
- 2 cups cooked pasta (e.g., macaroni, penne, or shells)
- 1/2 cup breadcrumbs (for topping)
- 1 tablespoon olive oil or melted butter (for breadcrumbs)
Instructions
- Preheat the Oven:
- Preheat your oven to 375°F (190°C). Lightly grease a baking dish.
- Make the Cheese Sauce:
- In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1 minute, stirring constantly. Gradually whisk in the milk, ensuring no lumps form. Cook for 3–4 minutes, or until the sauce thickens.
- Remove from heat and stir in the cheddar cheese, Dijon mustard, salt, black pepper, and garlic powder. Mix until smooth.
- Combine the Ingredients:
- In a large mixing bowl, combine the cooked pasta, tuna, peas, and sweetcorn. Pour the cheese sauce over the mixture and stir until evenly coated.
- Assemble the Mornay:
- Transfer the mixture to the prepared baking dish. In a small bowl, combine the breadcrumbs with olive oil or melted butter, and sprinkle over the top. Add extra grated cheese for a cheesier topping if desired.
- Bake the Casserole:
- Bake in the preheated oven for 20–25 minutes, or until the topping is golden brown and the dish is bubbling.
- Serve and Enjoy:
- Let the Tuna Mornay cool for a few minutes before serving. Pair with steamed vegetables or a side salad.
Notes
- Substitute cheddar with Gruyère, mozzarella, or Parmesan for a different flavor profile.
- Make it gluten-free by using gluten-free flour, pasta, and breadcrumbs.
- Add chopped cooked bacon or sautéed mushrooms for extra flavor.
