Vegan Leek & Polenta Flan

  • Posted in Main courses
JUMP TO RECIPE
vegan leek & polenta flan

This vegan leek & polenta flan is very nutritious and tasty – great for those summer al fresco meals with salad. It’s also great in winter to remind you there is such a thing as summer!

I love the combination of leeks, onions & herbs & smothering it all in well seasoned polenta mixture tops it off well. Chesnut, oyster, king oyster or white mushrooms are best to use as field mushrooms would colour the filling too much.

I’ve used mainly wholemeal flour for the pastry case so using a loose bottom flan tin is best. This is because wholemeal pastry is difficult to work with and the loose bottom makes it easier.

I like recipes that don’t leave you too many odds & ends in your fridge to go off, so this uses a whole leek.

Polenta is very versatile indeed and super nutritious. This uses a fine grade of polenta, where my other recipes use medium or coarse, but medium would work too.

This dish will go well with a simple green salad, or my herby summer potato salad. It will also go with garlic bread if you have any in the freezer ready to go.

If you use medium polenta, then you can use it in my other tasty polenta cakes: blueberry polenta cake & marmalade polenta cake.

Pastry making is a bit of an art, but once you’ve mastered it, there are loads of uses. Most tarts or flans require pastry so it’s well worth mastering.

Enjoy making this vegan leek & polenta flan – then try banoffee pie, cherry bakewell tart, pumpkin pie, or pecan pie!
