Pi day is coming up quickly! What are the technical differences between pie, tart and quiche? Tarts are sweet. Here are my observation so far:

  • Pies can be either sweet or savoury.
  • Quiches must be savoury.
  • A pie can be with and without a lid. Tarts and quiches don't have lids. (See “Pie” vs “Tart”?)
  • Tarts can be small. Quiches and pies are cut up and shared.
  • Both pies and tarts can contain fruits.
  • All have a pastry bottom.
  • All may be served hot or cold, depending on the filling.
  • All are rounded.

Please feel free to correct me. Sorry to be too technical. I'd like to avoid the embarrassment of bringing a tart or a quiche instead of a pie for Pi day parties.

  • Go crazy, take a fried pie!

  • Don't take a Quiche! It is neither a pie, nor a tart, but more of a egg and vegetable brunch dish.

  • @elbrant for the original Quiche from Lorraine that’s certainly not true.

Pie and tart are regional (North American versus Western European) terms for essentially the same thing. Some will argue that the pans make the difference (see below), but I don't buy that story.

There are some stylistic differences that appear quite often, but nothing that makes them truly different things:

  • Pies tend to be deeper, and have more filling
  • Pies tend to be made in a shallow, sloped sided baking pan called a "pie pan; whereas tarts tend to be made with only a ring, or a tart mold which consists of an outer ring with a removable bottom plate. Tart pans or rings tend to have vertical sides, not sloped ones.
  • Tarts usually only have a bottom crust
  • If the recipe is from France or cooks of a French cooking tradition, it tends to be called a tart; if it is from North America, it tends to be called a pie
  • Pies often feature a flakey short crust, or a crumb type crust, whereas tarts often feature a pate sucre type crust, but again this is far from universal
  • Pies are usually served from their pan, where tarts are almost never served from their ring—this may be as close to a defining difference as there is!

Both tarts and pies can be made in a variety of sizes, including appetizer or finger food sized, personally sized, or family sized.

In North America, sometimes a turnover (like an empanada or pastie, but hand-sized) which is baked or fried is also sometimes called a pie, hand pie, or even fried pie.

The word pie is also used in England and North America for a class of casseroles made with a top crust, such as shepherd's pie (mashed potato crust), steak and kidney pie, or chicken pot pie.

There is also the gallette which is a pastry made free form without a pan or mold, by making a crust, adding filling, and folding the sides partially over towards the center. This is essentially a free form tart or pie.

Quiches are a savory pie or tart whose filling is based on an egg based custard, often with cheese as well.

Oh... and if it is from New York, made with a yeast raised crust, and covered with cheese and hopefully pepperoni, it is definitely a pie :-)

  • Thanks for the info on regional differences. On one hand, I could bring a fried pie since there's no detailed spec of the "pie" for the Pi day parties. One the other hand, such a non-rounded pie could cause a civil unrest on Pi day at 1:59. :-)

  • One notable difference between quiche and pie is the crust - non-flaky (short) vs. flaky (long).

Tart usually consists of egg yolk and powdered sugar.

Pie usually consists of only castor sugar.

Quiche usually consists of shortening but no sugar.

Tart can be sweet and savoury.

Pie can be sweet which filled with fruit fillings.

Quiche can be savoury only.

All of these pastry can be shaped from small to big.

About the topping, it is up to you.

    Where do you come up with these definitions? They seem very arbitrary. Many, many pies are meat-based. What does "tart usually consists of egg yolk and powdered sugar" mean??? What about the crusts? Please explain your answer more thoroughly.
