Vegan chickpea tuna and potato mornay is based on an old British dish but there is a similar Australian version of a mornay that features pasta or noodles that is also known as a tuna casserole pasta bake. A mornay is defined as a dish that is cooked in a cheesy, creamy sauce.

This vegan chickpea tuna and potato mornay features chickpeas, potatoes, and spinach as the star of the meal enveloped within the tastiest, savoury, fresh herb creamy sauce. And topped with cheesy nutritional yeast and crispy breadcrumbs.

Perfect for a starter, side-dish, light lunch, but also good enough for the main event.

Vegan Chickpea Tuna And Potato Mornay

This meal is easy to prepare yet delivers on tasty, moreish fresh flavours. First the potatoes are boiled or steamed until soft. I use baby or new potatoes but really any type of potatoes can be used. Once cooked the potatoes are drained and placed into a casserole dish that has been lined with fresh spinach. A sprinkle of dried or chopped fresh dill is added to the potatoes.

While the potatoes are simmering the chickpea tuna is prepared. To begin the red onion and celery is fine diced and added to a small bowl, along with fish seasoning (dried herb and spice mix), lemon juice, and sweetcorn. This mixture is seasoned to taste with salt and pepper.

Next the chickpea tuna mix is sautéed in a pan with either one tablespoon of heated oil or about 1/2 cup of veggie stock, for 10 minutes. Plain flour is stirred through the chickpea tuna mix and cooked for a further 1 minute before plant milk is slowly poured in to create a creamy sauce. The sauce is seasoned with salt, pepper and cayenne pepper to taste. I usually add a few pinches of cayenne just for the warm flavour as my family prefer the sauce not to be too spicy!

The creamy or mornay sauce is simmered gently for around 3-4 minutes and then a tablespoon of white wine vinegar is added to provide delicious tangy notes. The sauce is poured over the potatoes in the casserole dish. A topping of nutritional yeast flakes and breadcrumbs is sprinkled over.

Now all that needs doing is for the chickpea mornay to bake in the oven for around 25 minutes until lightly golden and bubbling. Throw over some chopped fresh parsley to garnish and compliment all those fresh, creamy, herby flavours.

Depending on how small you diced your red onion and celery they may retain a slight crunch by the end of cooking time, but this is actually welcome as the texture and flavours this brings, does add much to the finished dish.

Recipe Notes And FAQS

How do I store leftover chickpea tuna and potato mornay?


Leftovers?!! That has never happen in our house with this recipe! But of course if serving less people or smaller appetites leftovers can happen.

Store leftovers in the fridge, within a covered container, for up to 3 days.

How do I reheat leftover chickpea tuna mornay?



Remove leftovers from the fridge about 30 minutes before reheating. Place in a a baking dish, cover with a layer of foil, and reheat at the cooking temperature until piping hot throughout. Check after 20 minutes for doneness.

Can I prepare chickpea tuna and potato mornay in advance?


Yes. This recipe can be prepped a day or two in advance and kept covered in the fridge.

Remove from the fridge about 30 minutes before baking to remove the chill and reduce cooking times.

Add an extra 10 minutes or so to the baking time if required, to ensure the mornay is piping hot throughout and bubbling.

Is this chickpea tuna and potato Mornay suitable for gluten-free diets?


Absolutely, yes.

Use a gluten-free plain flour mix for the sauce, and gluten-free breadcrumbs for the topping. I used gluten-free rice breadcrumbs.

Finally ensure that the fish seasoning herb blend used is free of gluten ingredients, and if a vegan margarine or vegan stock is used to cook the chickpea tuna mix make sure those are also free of gluten ingredients.

How do I make a tuna chickpea salad that I could have on a sandwich?


It is easy to prepare tuna chickpea salad that is super tasty as a sandwich filling. I prepare this all the time for my family and my son enjoys taking it for school pack lunch especially as a tortilla wrap filling.

Prepare the chickpea tuna mix according to the recipe but don’t cook it.

Instead add enough vegan mayonnaise to create a creamy tuna mayonnaise texture. Give the mix a little mash to break up some of the chickpeas.

Add enough salt and pepper to taste. A dried seaweed nori sheet ripped into pieces and mixed through gives an extra fishy-sea flavour.

That’s all there is to creating a really easy simple chickpea tuna mayonnaise sandwich filling. Try a few scoops as a baked potato filling. So refreshing and delicious.

What is fish seasoning?


Fish seasoning is usually just a mix of herbs and spices that is designed to season fish. As the mix is simply different plant ingredients it is perfect for vegans and plant-based diets especially when re-creating a vegan version of a fish dish.

Below is a photo of the fish seasoning that I have use for this recipe. Any fish seasoning blend can be used although do check the ingredients. Be extra careful if your dish has to be gluten-free in case any wheat or similar ingredients have been added to bulk out the seasoning.

If you can’t source any fish seasoning then its easy to mix up your own herb blend if you have the individual herbs or spices to hand. The herb blend I used was made up of ‘ fennel, parsley, chives, orange, tarragon and chervil’. Instead of the dried orange some fresh lemon or orange zest would be tasty. Also fresh herbs could replace the dried.

Although technically any seasoning mix or blend can replace the fish seasoning.

What is a mornay?


A mornay is a French term for basically a dish prepared with a creamy sauce that can be flavoured with herbs, spices, cheese, etc.

There is also a mornay sauce that is a béchamel sauce with cheese added. A mornay sauce is commonly served with pasta dishes.

In Australia a popular dish is tuna pasta mornay or tuna casserole bake which has tuna and pasta mixed through a creamy sauce, added to a casserole dish, and topped with cheese and breadcrumbs before being baked until crispy.

In Britain, a mornay is usually prepared with different types of fish or seafood, and sometimes with veggies or potatoes added. A crispy topping is also a common addition.
