Roast squash, caramelised onion and pesto tarts

A festive and seasonal version of my pizza tarts.

The same wholesome base but topped with pesto, caramelised onions and butternut squash — The perfect pairing of textures and flavours.

I’ve used basil for the pesto here, but you could swap for kale for a more seasonal twist.

They not only look pretty, I think they would make a delicious festive starter served with salad and some tangy chutney. Or perfect as part of a party spread with salad, dips, nibbles, etc.

Versatile and delicious, I hope you enjoy xx
