Tuna Mornay

The story

Tuna mornay became a post-war Australian household staple through canned tuna, packet pasta and the popularity of white sauces. It made an affordable pantry protein into a family casserole. The dish is comforting through creamy sauce, soft pasta and crisp topping, while peas or corn add sweetness. Good seasoning and acidity prevent blandness. It remains a nostalgic weeknight dinner and freezer-friendly bake. Many Australians recognise it from childhood even if modern versions use fresher herbs and better cheese.
