Method

  1. Heat 3 tbsp oil in a frying pan, add the onion and gently cook until softened, about 10 mins. Add the thyme, vinegar, salt and pepper and cook for 5 mins more, stirring occasionally to stop them burning. Set aside to cool.

  2. Heat oven to 200C/180C fan/gas 6. Roll out the pastry, trim to a 28cm round, then put on a non-stick baking sheet (or one lined with baking paper). Fork the pastry all over.

  3. Spread the onion over the pastry to within 3cm of the edge. Tear the prosciutto into strips and arrange over the onion in a rippled effect. Arrange the mushrooms on top and brush them with the reserved oil. Slice or crumble the cheese and arrange over the tart. Season with salt and pepper.

  4. Push the side of the tart up with your fingers to form an edge. Bake for 30-35 mins until the pastry edges have puffed up and the mushrooms are tender. Cool for a few minutes, then scatter with rocket just before serving.

A firm favourite in our family. Easy and quick to throw together when friends are visiting or just a relaxing supper for two. Lost count of how many times I've made it by now and always have people asking for the recipe.

Made for my hubbie's birthday lunch... well received instead of Delia's very fattening bacon and egg quiche made with cream! ;-) Changed pastry for filo, used tomatoes as well, I would add more goats cheese next time and maybe a little more balsamic vinegar but absolutely gorgeous!

It's ok but I found it rather dry and probably wouldn't make again.

Excellent recipe which I made when we had friends over for for a weekend lunch buffet. Followed the recipe, except that used soft goats cheese rather than hard, and crumbled that on and it worked fine. As the proscuitto is so thin and shrivels up, 4 slices weren't really enough so next time I think I would double that quantity. Other half doesn't like to think he's eating vegetarian, which it nearly was (although would be a nice veggie dish if you omitted the proscuitto anyway).

I really loved this. I didnt have any Prosciutto so I used pancetta which I think made it a little chewy in places so I will be making sure to use prosciutto in the future. I thought the whole mushrooms would be a bit too much so I sliced them instead and It was great! Will definately be making again!

Was able to prepare the onions the previous day and keep them over night in fridge ready to assemble as it was for a lunchtime meal for friends. Everyone enjoyed it including the two salads. Used the smaller mushrooms next time I made it..Lovely flavour with the onions.

didnt have prosciutto so fried up some bacon bits instead. also lined pastry base with some cream cheese, used mushroom stalks in an omlette - so no waste, tasted great.
