Tuna mornay is a pantry-friendly dinner that many Australians grew up eating on weeknights. Canned tuna and peas are folded through a cheesy white sauce, topped with breadcrumbs and baked until bubbling. It is mild, creamy and cheap, and it is served over rice, pasta or mashed potato. A little mustard and lemon juice stop the sauce from tasting heavy.
Instructions
- Heat the oven to 200°C (400°F) and grease a 1.5 litre (6 cup) baking dish.
- Melt the butter in a saucepan over medium heat and cook the onion for 4 minutes until soft. Stir in the flour and cook for 1 minute.
- Gradually whisk in the warm milk, stirring constantly until smooth. Simmer for 4 to 5 minutes, until the sauce is thick enough to coat a spoon.
- Take the pan off the heat and stir in the mustard, the 120 g of cheese, lemon juice, salt and pepper until the cheese melts.
- Fold in the tuna, broken into chunks, along with the peas and parsley. Pour the mixture into the baking dish.
- Mix the breadcrumbs with the remaining cheese and scatter over the top. Bake for 20 to 25 minutes, until golden and bubbling at the edges.
- Rest for 5 minutes, then serve over rice or pasta.
Tips
- Use warm milk and add it slowly so the sauce stays smooth. If lumps form, whisk hard or blitz briefly with a stick blender.
- Add a handful of sweetcorn or sautéed mushrooms for extra bulk, or swap the tuna for flaked cooked salmon.
