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.
what would you serve your onions with?

Wouldn’t have thought of using whole onions. I love anything with onions.

Me too Mandy, but Dave is not mad about them 🙂
You had me at onion. Gorgeous.
Thank you 🙂
Oh that’s so clever! I thought that you’d have to sweat the onions down but this is much easier 😀
It worked so well even Dave at some 😉
What a clever idea…I love baked onions.
Thank you Karen, me too!
Onions are one of those underrated vegetables, and yet when cooked correctly can really shine and be the star! This dish does exactly that, it looks delish!
Thank you Lisa 🙂
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.
I never look at the calorie count 😉
This looks so good~ Have always wanted to make an Onion Tart, think I’ll try this recipe! Lynn @ Turnips 2 Tangerines
Let me know what you think if you do!
Will do~Lynn

That is so beautiful. Green salad and walnut salsa!
I love the sound of that Tammy 🙂
Gorgeous and I think I’d serve this as a veggie main course with a lovely salad or some green beans 🙂
I think the green beans would compliment this dish perfectly 🙂
This recipe looks amazing!
thank you 🙂
I like fried onions, I usually shred it, but I like your version as well 🙂
Fried shredded onions are a firm favourite of mine 🙂
What a great idea to make a savoury tart tatin. Looks gorgeous!
thank you Claire 🙂
This is so clever! I’ve not seen a savory tar tatin recipe before, but it makes great sense.
I want to make a fer more varieties!
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
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 🙂
this looks wonderful–i will have to try it soon–and it is all vegetarian
I should try and do more vegetarian meals Usha 🙂
I love onions!
Me too, but Dave is not that keen!
This looks so special and delicious. Where can one buy those Italian onions? They look quite small. Thanks for another divine recipe, Tandy. 🙂
They are from Woolworths AD, and thank you for the compliment 🙂
MMMMMM8 I love this a lot! I would serve this with a lovely seasonal sald with a lovely thyme dressing! & home-made sourdough bread!
that sounds delicious Sophie 🙂
Sounds and looks delicious!
Thank you Tok 🙂
How did I ever miss this one? What a perfect holiday dish!
thanks Tammy!
