Recipe Information
Ingredients
- 3 tablespoons butter
- 1 large leek, thinly sliced
- 3 tablespoons all-purpose flour
- 2.5 cups milk
- 1 cup sharp cheddar cheese, grated
- 0.25 cup parmesan cheese, grated
- 1 teaspoon orange zest, finely grated
- 2 tablespoons orange juice, freshly squeezed
- 2 cans canned tuna in spring water, drained and flaked
- 0.75 cup frozen peas, thawed
- 0.5 cup breadcrumbs
- 1 tablespoon olive oil
- to taste salt
- to taste pepper
- 12 ounces pasta, such as penne or macaroni (optional)
Instructions
Preheat your oven to 375°F (190°C) and grease a medium-sized baking dish.
In a large skillet over medium heat, melt the butter. Add the thinly sliced leek and cook for 4-5 minutes until softened but not browned.
Sprinkle the flour over the leeks and stir constantly for 1-2 minutes to form a roux.
Gradually add the milk, whisking continuously to avoid lumps. Cook until the sauce thickens and is smooth, about 3-4 minutes.
Reduce the heat to low and stir in the sharp cheddar cheese and parmesan cheese until melted and smooth.
Add the orange zest, orange juice, salt, and pepper to the cheese sauce and stir to combine. Taste and adjust seasoning if needed.
Gently fold in the drained tuna and thawed peas, making sure everything is evenly combined.
If using pasta, cook according to package instructions, drain, and mix into the tuna mornay mixture. If not using pasta, move to the next step.
Pour the mixture into the prepared baking dish, spreading it out evenly.
In a small bowl, mix together the breadcrumbs and olive oil. Sprinkle the breadcrumbs evenly over the top of the mornay.
Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and the filling is bubbling.
Remove from the oven and let stand for 5 minutes before serving. Enjoy!
