How to Make Tuna Mornay

Tuna Mornay is a tremendously frugal dinner and tasty too! Best of all, you can feed a family of four for under $10! You can substitute the tuna for salmon if you aren’t a tuna fan.

This delicious Tuna Mornay can be ‘bulked up’ with loads of cooked brown rice or pasta and served with a salad to make it a healthy and cheap weeknight dinner for the whole family.

This dish is just so amazing as the ingredients are inexpensive but this doesn’t in any way taste cheap!


  1. Melt butter in frying pan, add the diced onion and fry for approx. 3 mins until soft.

  2. Add flour and constantly stir until mixed in.

  3. Slowly add milk and cream, stirring until mixture thickens. Stir in cheese, broccoli florets, tuna, Worcestershire sauce and season with salt and pepper.

  4. Mix well until heated through, then top with grated cheese before serving.

  5. Serve with pasta or rice (I like to mix my pasta through the sauce before serving).

Recipe Hints and Tips:

  • You can also top the Tuna Mornay with breadcrumbs and a few knobs of butter and place under the grill.
  • Tuna Mornay is not suitable to freeze. Keep refrigerated in an airtight container for up to 2 days.
