    This mushroom tart with feta and thyme is so simple to make at home and keeps for up to 3 days.

    It is the perfect lunch item, or pack it ip and take it on a summer picnic. Plus being free-form you don't need a pie tin and there is no chance of it sticking.

    • Rustic Mushroom Tart with Feta and Thyme

    How to make a tart without a tart pan

    You won't need a tart pan for this rustic mushroom tart. You can make this with just a sheet pan.

    • First roll the pastry out slightly so you have a square.
    • Make a thick filling that includes an egg, to ensure it doesn't run off your pastry.
    • Pile the pastry with the tart filling, leaving a 1.5 inch (4cm) gap around the edge.
    Pastry piled with the cheese filling for the mushroom tart.
    • Pile the cooked mushrooms on top.
    • Crumble over the feta and fresh thyme leaves.
    • Then fold over the pastry edges.
    Prepared tart before it goes into the oven.
    • Bake the tarts in a hot oven so the egg in the filling sets quickly and the pastry crisps up.

    What to serve with this rustic mushroom tart.

    This tart is wonderful warm or at room temperature. I love it as a brunch with the girls....especially if there is a side order of Charred Grapefruit and Basil Gin and Tonic.

    To turn it into a lunch I added a mixed leaf green salad dressed with a simple dressing:

    To make it more of a dinner you could add some potatoes, I'd suggest my hedgehog potatoes because EVERYONE loves them :D.

    Rustic Mushroom Tart with Feta and Thyme Anecdote
    (aka my recipe ramble for those who love the waffle)

    My love of rustic, or free-form tarts as they were called when I was working in the kitchens, started way back somewhere in the late 1990's (EEEK!!! I am old!)

    The hotel used to have a free-form crab and wild celery tart on the lunch menu. It was, well word can't describe it!!! It was just sublime.

    The filling was so perfect, but the beauty of the tart was the rustic looking case. So puffy and delicious, but so simple to make!!!

    Plus it makes it so much easier!! One less thing to wash-up (always important) and no chance of the tart sticking to the base.

      The egg and cream cheese, garlic, onion mixture was very runny, I tried to make a wall with the puff pastry to old it in, but once in the over the liquid ran over and so there was no lovely crust. The interior was delicious, but marred by its looks.

        Did you use low fat cream cheese? Or a spreadable cream cheese? I have had that happen when I used some spreadable cream cheese, it was just too runny.
        Hopefully that was the issue, but if not let me now and we can try a bit more trouble shooting ๐Ÿ™‚
