Tomatoes on a mattress of French Dijon mustard is a superb traditional savory tart in France. Don’t fear; mustard’s energy lowers when cooked. Listed below are my greatest suggestions and variations to make it straightforward and pleasant. Connoisseur possibility with feta or mozzarella cheese.

For me, the distinction between a quiche and a savory tart is that quiche is a spread that all the time has an egg-and-cream custard with varied fillings, from the traditional quiche Lorraine with bacon to all of the doable variations with salmon, spring vegetables, caramelized onion…
As for savory tart, tarte à la tomate, as we are saying in French (we don’t point out with Dijon mustard as when referring to tomato tart, it’s apparent we add mustard!!!) is likely to be the very best recipe, don’t you suppose?
For me it really competes with my mother’s roasted bell pepper tart, a variation on the quiche with peppers on a mattress of tomato coulis.
The tart pastry
You should utilize do-it-yourself or store-bought shortcrust or puff pastry. Right here, I recommend a puff pastry.
Roll out the pastry in a pie dish. I like to recommend a steel dish that conducts the warmth higher and provides you better-cooked dough than a porcelain or glass dish.
Or, folding over the perimeters, you may make your tomato tart in a galette form (we name it tarte rustique / rustic tart). That is additionally a good suggestion and infrequently makes a really fairly presentation.
Which mustard to decide on
The well-known tomato tart is most frequently made merely with the traditional Dijon mustard. Don’t fear; the energy of the mustard diminishes with baking, because it does in an different recipe I cook dinner fairly often, pork meat coated in mustard. Mustard’s energy lowers however style stays.
So select Dijon mustard or substitute it with old style grainy mustard. I as soon as tried it with tarragon mustard, which was additionally good. So have enjoyable with flavored mustards…
The traditional recipe for this tomato tart usually makes use of mustard solely. I like to combine mustard with cream cheese or crème fraîche, which I unfold on my pie pastry. I’ve advised this within the beneath recipe.
The proportion is half and half for a spicy style; in any other case, one-third mustard – and two-thirds cream cheese.

Tomatoes
Select plump tomatoes with somewhat juice. Right here, I had oval-shaped tomatoes that had been curiously seedless and dense.
To make sure that the tomatoes don’t give off an excessive amount of water throughout baking, we lower them into slices, take away the seeds, and place them in a dish lined with kitchen paper to launch as a lot juice as doable.
I begin with this step and depart them like that for about fifteen minutes, which is the time it takes me to organize the sautéed onion and the tart base (rolled-out pastry lined with the mustard combination).
Play with tomato varieties and colours: the black Crimean tomato, the pink, orange/yellow pineapple tomato and the inexperienced zebra tomato, and have enjoyable making a rainbow.
However no matter you do, be beneficiant with tomatoes and don’t hesitate to both overlap the tomato slices or make a number of layers (your tart can be extra balanced than if you happen to solely have one layer of tomatoes) or prepare them properly, as we do for Tian.
Reducing cherry tomatoes in half and scooping out their juice can also be enjoyable, however it’s numerous work! This can be a fast, no-fuss recipe.
Non-compulsory: sautéed onions
Including sautéed onions is totally elective, it’s my private contact for a variation on the standard recipe.
Simply sauté minced onion and coarsely chopped garlic in olive oil with herbes de Provence or recent thyme. I simply sear them or cook dinner them virtually candied, and prepare the onions on the mustard earlier than including the tomatoes. You might also add them on prime of tomatoes, as you want.
Non-compulsory, add cheese
This tart is ideal eaten heat out of the oven or chilly for a picnic or a easy lunch on the go.
You possibly can go for a variation with cheese, which takes connoisseur pleasure to the subsequent degree! So, grated cheese (Gruyère or, higher nonetheless, Comté or Parmesan)? Not for me. Or mozzarella or feta? Why not…
Choice 1 = feta Select a Greek PDO feta cheese made primarily from sheep’s milk. 5 to 10 minutes earlier than the top of baking time, or when reheating the tart, crumble the feta right here and there over the tart and place again within the oven to heat up and soften somewhat the cheese.
Choice 2 = mozzarella Use mozzarella or, higher nonetheless, burrata with a runny heart. For mozzarella, proceed as for feta however if you happen to select burrata, I like to recommend inserting it within the heart of your tomato tart, simply out of the oven if you come to the desk. Open it if you lower your tart, and ensure to place a bit on every slice if you serve it.
You typically see images of tomato tarts with slices of mozzarella sandwiched between the tomato slices, however I wouldn’t suggest it because the mozzarella doesn’t have to spend as a lot time within the oven.
Choice 3 = recent goat cheese, not dangerous both. Proceed as for the feta.
And coming quickly, a variation of this tomato tart with tuna.
