Onion Tart Tatin | Savoury Tarte

A few weeks ago we were having friends over for dinner. It was at the same time that I was recipe testing in order to review James’s Desserts. I had some lovely Italian onions in my pantry that needed using up and I decided to make a tart tatin with them. This to me would be a great accompaniment to the roast chicken I was making. I like to be able to cook dinners during the week that are not too fussy as I don’t have much time for preparation beforehand. When entertaining I also want to spend as little time in the kitchen as possible as I want to be with my guests. A tatin for dessert has always worked for me in this regard, as it can be prepared ahead of time. And so, I knew for sure that a savoury tatin would be perfect as well. The onions come out sweet and soft and unctuous. The morning before I posted the review for James’s Desserts showing my onion tart tatin, Sam published a recipe for easy roasted onions with thyme. I was going to delay this post as Sam and I have some of the same readers, but she asked if I would please publish it so that she can link to it in her series on onion recipes. I hope you enjoy this as much as we did.

  1. Looks tasty!

    I was wondering the calories it has in it co’z I’m in a diet. Hope it won’t affect at all.

  2. I always think it’s serendipitous when bloggers cook/bake the same thing on the same day. I mean.. what are the chances with all the recipes in the world:) Yours looks fantastic, I agree, how wonderful it is to prepare ahead so you can enjoy your guests! xx

    1. I sometimes see three or four bloggers post the same type of recipe in one day and it always amazes me at the synchronicity of it 🙂

  3. This looks so special and delicious. Where can one buy those Italian onions? They look quite small. Thanks for another divine recipe, Tandy. 🙂

  4. MMMMMM8 I love this a lot! I would serve this with a lovely seasonal sald with a lovely thyme dressing! & home-made sourdough bread!
