Roast Squash, Caramelised Onion & Pesto Tarts
Festive roast squash, caramelised onion & pesto tarts – a wholesome base topped with pesto, caramelised onions and butternut squash – delicious!
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
