Author Notes

This recipe is a summer take on the classic French apple tart, tarte tatin. Slow-roasting plum tomatoes in the oven intensifies the sweetness of the tomatoes and preserves their shape, while preventing them from being watery, which would make the puff pastry soggy. A layer of caramelized onions pairs beautifully with the roasted tomatoes. Serve it with a dollop of crème fraîche to mimic the classic pairing of tarte tatin with vanilla ice cream. Bon appétit! —Beautiful, Memorable Food

Test Kitchen Notes

Loved this tart—excellent flavor, and cutting out a round of puff pastry instead of making regular pastry dough made this tarte tatin much more simple than other recipes I've seen.

This recipe can be streamlined a bit as far as order and method goes: Caramelize the onions in a separate pan. Caramelize the sugar, vinegar, and seasonings in the cast iron. Add tomatoes. Roast. Add onions. Top with puff pastry, turn up the heat, and bake till done, then invert when slightly cooled. But the flavor was perfect: Right amount of sugar against the tomato's acid and simple with the puff pastry. The best part about this tarte tatin is that it looks fancy and complicated but it's really quite simple. —Omeletta

What happens to the juices & caramel vinegar mixture ? Is it deglazed further?

If you don't have an enameled cast iron skillet, what do you recommend cooking this in?

@mark Wolf and @duckfat-- thank you for the insight! Yes, actually, I used an enameled cast iron, not regular cast iron, and your point is well taken. Will correct in the recipe, thanks!

This looks great, but the instruction to cook and assemble this in an iron skillet gives me pause. Between the tomatoes and the added vinegar, I'm concerned that the skillet might impart a metallic taste to the finished tart. I have learned from experience that acidic foods and iron cooking utensils, even those that are well seasoned, usually make poor companions. Or maybe I'm just particularly sensitive to the taste....

The same thought occurred to me. Fortunately, I have an enamel skillet that will save me the worry!

thank you duckfat - I FORGOT about using my enameled skillet! Duh... I agree with mark Wolf: I would not like to do this vinegar/tomato combo in regular cast iron.
