Method

  1. Heat oven to 180C/160C fan/gas 4. Pulse the flour, oats and butter in a food processor until crumb-like, add the grated carrot and continue to process until the mixture comes together to form a ball. Alternatively rub the butter into the dry ingredients, add the carrots and press together until a ball is formed. Carefully roll out the pastry and line a metal 25cm pizza dish or shallow tart case. Chill.

  2. Gently cook the onions in oil for about 15-20 mins until beginning to caramelise. Place the beetroot in the pastry case and cover with the onions. Whisk the eggs and milk together, season and pour over the onions and beetroot. Bake in the oven, lowering to 160C/140C fan/ gas 3 after 15 mins, for 40 mins or until firm and golden.

OK recipe but there other beetroot quiches on the website that are tastier.

This had a nice taste, but I'm not sure I would bother making it again. My dish was a little bit smaller than the size given in the recipe and I reduced the quantity of milk and eggs, but it still ended up overflowing! The beetroot was so faffy to grate and I ended up with juice all over the place. I baked the pastry case blind for about 7 or 8 minutes, then added the filling. It didn't really have the texture of a quiche because there was so much beetroot and onions (even though I reduced these too). I added a little bit of brown sugar and balsamic vinegar to the onions and put a sprinkling of oregano on top. Took longer to cook than stated and was still a bit sloppy. Probably wouldn't make again.

This is the second time I have made this tart and each time it's been surprisingly great and quite easy and economical to make. I kept to the recipe but added balsamic to onions for flavour and squashes out as much moisture from the fresh beetroots as my hands would allow. Sprinkled with some cheddar on top. The kids enjoyed it and even the baby ate some. Didn't find it as bland as some of the other comments, but could have added herbs which would have been great too. A winner!

Have just eaten this for lunch ... makes a pleasingly thick tart, but I agree with several others, it is a little bland. Thanks to the comments, I was prepared for this and whipped up a quick leftover-salad-bag-pesto to top it with, which worked well. Made several ingredient changes. Sized down for smaller tin. Swapped carrot for chopped fresh parsley and coriander, and had to add a splash of water to help bind the pastry together. Pastry tended to break up, but was easy to press pieces together once in the tin. Used leeks instead of onion as these needed using up. Only grated one beetroot due to re-sizing. Didn't have any problems with a soggy bottom ... tee hee.

Very tasty. I could have made 2 tarts with all these ingredients and ended up freezing some beets and onions for next time. Goats cheese is a must.

i ended up making this with fresh beetroot, think the vacuum packed kind would definitely have been too watery. It was better served lukewarm, loved the carrot and oat pastry. Will make this recipe again! Some fresh thyme in the pastry and goats cheese on top were good additions

I was intrigued by the pastry made with grated carrot and oats, but it should be baked blind, as the main cooking time at a relatively low oven temperature and all the juices (250ml of MILK and the raw beetroot), leave the base raw! I would be prepared to have another go at this recipe, baking the pastry blind for a bit of crunch and then using some natural yoghurt and a bit of (low fat) cream instead of milk.

I made this using brown rice flour and quinoa flakes for the base -I wanted to try something gluten free as an experiment. I needed to add water to really bind it fully and ended up pressing it into the tart case, but it tasted great, crisp and nutty. I also experimented by adding sumac to the onions, which was more flavoursome than the plain one (I made 2 small tarts). I'll definitely make this again, and next time am going to try putting grated, or a little creamed, horseradish in with the beetroot.

Not sure why people are struggling with the seasoning!! It may not be listed in the ingredients but it does state in the instructions to season! Always on the look out for something a little bit different when my veggie mother in law comes to stay and this one definitely went down well. Followed the recipe to the letter. Didn't have a soggy bottom and it was extremely tasty and enjoyed by all who ate it! A big fat YUM!

Following recommendations by other members I add balsamic vinegar to the onions, as well as nutmeg and of course s&p. I used plain flour as didn't have any wholemeal and it was absolutely fine although I imagine it being better with wholemeal. Would consider this a SUCCESS and was enjoyed by all, including my partner who prior to this evening claimed he didn't like beetroot! None o us found this bland like there members mentioned, I would say that could be down to the quality of their ingredients. Fresh beetroot is definitely a must for this recipe and not packeted or pre cooked. I used a food processor with a grating attachment to grate the beetroot so didn't find that a problem at all. I ended up leaving it in the oven for an extra 20mins and blind baked the pastry for 7mins at the beginning first as recommended in a few comments. All in all a lovely dish which I will definitely be cooking again and again. The pastry was loved and commented on by guests with positive feedback too. Such a hit!
