Tuna mornay is a classic budget dinner that the whole family will love. Warm and soul-soothing, this recipe is so easy to make. It’s just a matter of pulling a few simple ingredients together that you’re sure to have lying around in the pantry and fridge, layering in a baking dish and popping under the grill until golden. It makes the perfect weeknight dinner!
If you’re trying to get your children to eat more fish, this is a great recipe to start with. Only using a small can of tuna, it’s not overpowering in flavour but they’ll still be getting that great omega 3 boost. For those who love their tuna, try adding two cans to the white sauce, if you like.
Got a bit more time up your sleeve? Instead of grilling the top of the tuna mornay, you can bake it in the oven until golden which will allow the flavours of the filling to develop even more and meld together. Want a crunchy topping like what Mum used to make? Sprinkle the top with breadcrumbs and bake until golden (if cooking under a grill, be sure to keep a close eye on the breadcrumbs as they may start to burn before the cheese gets a chance to fully melt).
We love that this recipe is a great base to build on for many other variations. Add chilli, green onion, fresh herbs, lemon, pesto or baby spinach leaves to your next batch. It’s giving serious comfort food vibes – just grab a bowl and dive right in!
