About Fish Mornay
Fish Mornay is a traditional Australian dish that brings together a love of fresh fish and creamy, comforting flavours. At its heart it is a delicious bake, usually made with tender fish, a rich cheese sauce and a crisp, golden topping. The dish is not only tasty but wonderfully versatile, since you can use all manner of fish and swap in different cheeses to suit your mood. Fish Mornay is a superb choice for special occasions such as holidays or family gatherings, and it never fails to win guests over. It sits comfortably alongside other coastal favourites of Australian cuisine.
Ingredients (serves 1–2)
- 250 g firm-fleshed fish (such as cod or salmon)
- 200 ml cream
- 100 g grated cheese (such as cheddar)
- 1 tbsp butter
- 1 tbsp plain flour
- 1 cup milk
- 1 tsp mustard
- 2 tbsp lemon juice
- Salt and pepper, to taste
- Fresh herbs, to garnish (such as parsley)
Shopping for the ingredients
When shopping for Fish Mornay, it is worth choosing fresh fish to get the very best flavour. A local fishmonger or a well-stocked supermarket with a good seafood counter is your best bet for quality catch. Make sure the other ingredients, such as the cream and cheese, are fresh too, so every element tastes at its best. If you cannot track down a particular item, ask at specialist shops or look for alternatives in a health-food store. The same fresh-is-best approach rewards you when making a Seafood Platter.
Preparing the dish
Before you start cooking Fish Mornay, it pays to get all your ingredients ready. Cut the fish into even pieces so they cook through at the same rate. Grate the cheese and set it aside within easy reach as well. Prepping everything in advance makes the cooking process far smoother and means nothing gets forgotten once you are busy at the stove.
Step-by-step instructions
- Preheat the oven to 180 °C.
- Melt the butter in a saucepan, then stir in the flour to form a roux.
- Slowly whisk in the milk until you have a smooth sauce, stirring continuously over medium heat.
- Add the cream, mustard, lemon juice, salt and pepper, and mix well.
- Stir the grated cheese through the sauce until it has melted.
- Place the fish in a baking dish and pour the cheese sauce evenly over the top.
- Bake in the preheated oven for around 20–25 minutes, until the top is golden brown.
Gluten-free / lactose-free version
For a gluten-free Fish Mornay, simply swap the regular flour for a gluten-free blend to thicken the cheese sauce. When buying cheese, look out for lactose-free options, which are now available in most supermarkets. Do the same with the other dairy ingredients, such as the cream, choosing lactose-free products throughout to guarantee a lactose-free dish. That way, anyone with an intolerance can still enjoy this delicious bake.
Tips for vegans and vegetarians
Vegans can recreate Fish Mornay using plant-based proteins such as tofu or seitan in place of the fish. For the sauce, a blend of cashew cream and nutritional yeast delivers that familiar cheesy flavour. A pinch of seaweed or algae flakes among the seasonings adds a subtle taste of the sea. The dish stays every bit as satisfying while suiting both vegetarians and vegans.
More tips and tricks
To coax the very best flavour from your Fish Mornay, try adding a few extra seasonings to lift the dish. A hint of nutmeg, for instance, gives the cheese sauce real character. Experimenting with different cheeses is rewarding too — a mature gouda or a touch of blue cheese both add a distinctive note. Above all, take care not to overcook the fish under the grill, so it stays tender and moist rather than drying out.
Adapting the recipe to your taste
Fish Mornay is easy to tailor to your own preferences. If you love your veg, stir some spinach or peppers through the cheese sauce to freshen things up. You can also build in other sauces as a base to combine with the fish for an exciting twist. Be creative and play around with different ingredients and variations until it is exactly how you like it. For an even more luxurious take, follow the same method with the shellfish in a Lobster Mornay.
Ingredient substitutions
If you do not have certain ingredients to hand, there are usually simple swaps. In place of fresh fish you can use tinned fish, which is often ready to go straight from the pantry. Instead of cream, plant-based milk or a mix of water and coconut cream lightens the dish nicely. This flexibility means you can still turn out a tasty meal even when a few ingredients are missing. A firm fillet like the one in a Barramundi recipe also works a treat here.
Drink pairing ideas
Plenty of drinks pair beautifully with a good Fish Mornay. A fresh Sauvignon Blanc is an excellent choice, its crispness complementing the fish wonderfully. For non-alcoholic options, sparkling mineral water or a homemade lemonade made with citrus fruits both work well. These drinks harmonise with the creamy character of the dish and let its flavours shine.
Serving and presentation ideas
Presentation can lift the whole Fish Mornay experience. Serve it in an attractive baking dish that shows off the creamy cheese sauce to full effect. Scatter fresh herbs such as parsley or chives over the top for a welcome splash of colour. An appealing arrangement on the plate — perhaps with a side salad or some roasted vegetables — turns your dish into a genuine showstopper. Serve it as part of a spread with crisp Fish And Chips for a coastal feast.
A bit of history
Fish Mornay has its roots in French cuisine, where bakes and cheese sauces have long been a staple. In Australia, however, it has become one of the country’s much-loved dishes, reflecting the abundance of the coastline and a national fondness for fresh, honest cooking. The dish is a lovely example of how culinary traditions borrow from one another, folding in local ingredients along the way. In doing so it keeps its original charm and flavour while adapting to regional tastes.
