June 11-19 marks the UK’s optimistically scheduled National Picnic Week. The weather has been hit and miss so far this summer but as a family we’ve grabbed every opportunity to eat al fresco. I’ve already shared my summer Mediterranean menu for six and then last weekend we got the picnic basket and blanket out for this mushroom filled feast on the back lawn.

These lovely dark portobello mushrooms are packed with flavour and laying them on sheets of baked golden puff pastry is a portable way to enjoy them outdoors. A pastry base spread with black olive tapenade boosts the umami factor. A 500g block of puff pastry is enough to make eight of these savoury puff pasties or you could use half the pastry to make something sweet for dessert. Baking time is under 15 minutes meaning you can maximise your time in the great outdoors.

Mushrooms are a versatile vegetable you can enjoy all year round and can make a valuable contribution to a healthy diet. Mushrooms are a good source of B vitamins, dietary fibre, anti-oxidents, a vegetarian source of protein and one of your five a day. What’s not to love?

You could serve these mushroom pastries also as a light vegetarian lunch or make them smaller as party appetisers. Truffle oil really ramps up the mushroom flavour if you have this but otherwise olive oil is fine.

Making portobello mushroom puff pastry tarts

You only need five ingredients to make these portobello mushroom tartlets – puff pastry, nice big dark portobello mushrooms, black olive tapenade, oil and a dab of egg wash to make the pastry golden.

Optionally you can add chilli flakes and garnish with fresh thyme. I admit, I add chilli to virtually everything I eat but you don’t have to!

This is a vegetarian recipe easily adaptable for vegans if you sub the egg wash with something else such as a mix of soy milk and agave nectar. Pre-rolled puff pastry in boxes is often made only with vegan ingredients rather than butter so you might not have realised you were already eating a vegan friendly product.
