Full disclosure: there is no tuna, vegan or otherwise in this dish.
Think of it more as an essence of tuna casserole because that’s what it is, but this vegan dish contains all the things you miss about this dish without any of the things you could do without.
Instead of tuna or vegan tuna products, I went with simple brown mushrooms. Sauteed in a pan until crisp on the edges and yummy.
Choose a noodle, cheese sauce and bread crumb topping and you’re good to go!
I opted for a creamy cheese sauce that used unsweetened oat milk and half the amount of cheese as similar vegan recipes, some of which might recommend coconut milk. Choose what fits your palate and your diet.
Bake it for 20 to 35 minutes in the oven, until the top is crispy brown and some of the noodles have a crunch.
The only thing missing? An ice cold drink, fit for a grownup.
