Sweet Potato, Gruyere & Rosemary Tart

2nd January 2016

This savoury Sweet Potato, Gruyere & Rosemary tart has become my go-to recipe for dinner parties: it’s cheap, easy and quick plus I know my guest will love it. Try it, and you’ll see what I mean.

I made this tart a few weeks ago when I hosted a Christmas get-together for friends.

My original idea was to have a few drinks and nibbles (and eat all the cakes I received in the Tesco Christmas Hamper). As usual though, the fear of leaving my guests hungry kicked in and I ended up making two of these tarts just in case. One remained completely untouched and it’s still in my freezer for one of those days I can’t be bothered to make dinner. But the other tart was wolfed down by my husband and my friends, and I also received many praises for it.

What makes it great is the winning combination of sweet potatoes with the nuttiness of Gruyère and the pungent flavour of rosemary. The recipe itself is a variation of an Italian tart with potatoes and fontina, so you can play around with the ingredients depending on your taste.

Peel and slice the potatoes as finely as possible. Place them at the bottom of the pastry dish in a spiral shape.
