Notes
Ingredients
Tuna – I just use cheap canned tuna. You can use tuna in springwater, brine or oil. The choice is yours. Fresh tuna that has been cooked and flaked can be used if you prefer. Use canned salmon or chicken if you prefer.
This is a tuna casserole without pasta but of course you can use any pasta you like and mix through before baking. Our keto pasta recipe is perfect for this too.
Cream – thickened or heavy cream is best. See below for substitutions if you need a dairy free tuna mornay recipe.
Cheese – pre-shredded mozzarella, cheddar, or any sharp flavoured tasty cheese can be used. You can also substitute parmesan if you prefer.
Vegetables – I have used mushrooms and zucchini for the main vegetables. You can use any vegetables you have on hand like pumpkin, broccoli, spinach, cauliflower or just about anything. Honestly, this recipe is so flexible.
What to serve with tuna casserole? Serve with side salad or some grilled or steamed vegetables.
How long can I store Tuna Casserole?
Keep in the fridge for 2-3 days.
Can tuna mornay be frozen?
You can freeze tuna casserole and thaw in the fridge overnight before reheating. This can be done before or after baking.
Tuna Mornay Thermomix instructions – I have included a thermal method and still bake in the oven. You can steam it if you prefer and use a butane torch to crisp up the top.
You can also use your air fryer to air fry tuna casserole. Prepare up to topping with the cheese and bacon and then place into a dish that fits your air fryer. Bake for 5 minutes at 200°C.
I use a skillet or cast iron pan to cook the tuna bake over the gas before baking. This can then be a one pot meal without having to dirty up another baking dish!
