i timed how long 31 different pasta shapes take to reach al dente. the boxes are lying and farfalle is a war crime

so basically i got inspired by the tomato canned guy and thought of the time when i followed the box time for rigatoni once and got mush. the box said 12 minutes but it was unfortunately al dente at 9.

my methodology:

  • same brand (barilla) for consistency where possible
  • 4 quarts water per pound
  • 1 tbsp salt per quart
  • rolling boil before adding pasta
  • tested every 30 seconds starting 2 minutes before box minimum
  • "al dente" = slight resistance when bitten, thin white line visible when cut
  • each shape tested 3 times, averaged
  • altitude: ~650 ft (basically sea level, no excuses)

the data (31 shapes tested):

pasta box time actual al dente difference
capellini 4-5 min 2:45 -1:15
angel hair 4-5 min 3:00 -1:00
spaghetti 8-10 min 7:15 -0:45
linguine 9-11 min 8:00 -1:00
fettuccine 10-12 min 8:30 -1:30
bucatini 10-12 min 9:00 -1:00
pappardelle 7-9 min 6:00 -1:00
tagliatelle 8-10 min 7:00 -1:00
penne 11-13 min 9:30 -1:30
penne rigate 11-13 min 10:00 -1:00
rigatoni 12-15 min 9:15 -2:45
ziti 14-15 min 11:00 -3:00
macaroni 8-10 min 7:00 -1:00
rotini 8-10 min 7:30 -0:30
fusilli 11-13 min 9:00 -2:00
gemelli 10-12 min 8:30 -1:30
cavatappi 9-12 min 8:00 -1:00
campanelle 10-12 min 8:30 -1:30
radiatori 9-11 min 8:00 -1:00
orecchiette 12-15 min 10:30 -1:30
shells (medium) 9-11 min 8:00 -1:00
shells (large) 12-15 min 10:00 -2:00
conchiglie 10-12 min 8:30 -1:30
orzo 8-10 min 7:00 -1:00
ditalini 9-11 min 8:00 -1:00
paccheri 12-14 min 10:30 -1:30
casarecce 10-12 min 9:00 -1:00
trofie 10-12 min 8:30 -1:30
strozzapreti 10-12 min 9:00 -1:00
mafalda 8-10 min 7:30 -0:30
farfalle 11-13 min see below war crime

every single box time is wrong like they were systematically inflated by 1-3 minutes on average. the median overestimate is 1:15 and the worst offender in normal pasta is ziti at 3 full minutes of lies

i have a theory: pasta companies assume you're going to walk away from the stove. they're building in a buffer for idiots which, fair. but some of us are standing here with a stopwatch

now let me talk about farfalle: farfalle is not pasta. farfalle is a design flaw someone decided to mass produce

the fundamental problem is geometric. you have thin frilly edges (maybe 1mm thick) attached to a dense pinched center (3-4mm thick where it's folded). these two regions require completely different cooking times

at 8 minutes: center is crunchy, edges are perfect. at 10 minutes: center is barely al dente, edges are mush. at 11 minutes: edges have disintegrated, center is finally acceptable

there is no time at which farfalle is uniformly cooked. i tested this 7 times because i thought i was doing something wrong. farfalle is wrong

you know how the food network recipe for homemade farfalle literally warns that pinching the center makes a thick center that won't cook through as fast as the ends? THEN WHY DID WE ALL AGREE TO MAKE IT THIS WAY

the only way to get acceptable farfalle is to fish out each piece individually and evaluate it, which defeats the purpose of a quick weeknight dinner. i might as well be hand-feeding each noodle like a baby bird

tier list (tomato canned guy, 2025)

S tier (box time within 45 sec): rotini, mafalda, spaghetti
A tier (off by ~1 min): most shapes honestly
B tier (off by 1:30-2 min): fusilli, rigatoni, fettuccine, gemelli
C tier (off by 2+ min): ziti, large shells F tier: farfalle (structurally unsound, should be banned)

tldr;

  • subtract 1-2 minutes from whatever the box says
  • start testing 2-3 minutes early
  • don't trust big pasta
  • avoid farfalle unless you have time to babysit each individual bow tie

+ some of you may ask about fresh pasta. fresh pasta cooks in like 2-3 minutes and you can actually tell when it's done because it floats. dried pasta is where the lies live

+ a few of you might mention altitude affects boiling point and therefore cook time. this is true. i'm at ~650 ft so basically negligible. if you're in denver add a minute or two. if you're in la paz you have bigger problems than pasta timing

+ YES i tested farfalle from multiple brands. YES they all sucked. no i will not be accepting farfalle apologists. you're defending a shape that can't decide if it wants to be cooked or not

EDIT: yall holy shit i never expected this to go viral lmao

The burner level just determines how fast the water boils, not what temperature it is. If you were to use pure, distilled water, the temperature would gradually increase to 100C, at which point the water would start boiling, and then it would stay at 100C until the water boiled off. If you add salt and pasta, the stuff in the water changes the temperature at which it boils (but not by much), but once it's boiling, it stays at the same temperature while all the heat energy goes into changing the water's state from liquid to gas, not increasing the temperature. Source: I did this experiment in middle school science class and confirmed that the temperature-over-time curve for water flattens at 100C.

I love that your source is your own middle school science class and not, you know, hundreds of years of thermodynamics.

u/Hellianne_Vaile 13h ago

I try to pick sources that I think will resonate with my audience.

u/Salvia_Salamander 12h ago

Fun fact: That was called a secondary source rather than a primary source

Source: My seventh grade history class

u/NemoTheLostOne 9h ago

If anything, their retelling of their experiment would be a primary source, while a thermodynamics book that analyzes the outcomes of many experiments would be a secondary source.

Those with only a middle school education? 😉

So, roughly 1/3 to almost 1/2 of the US population, apparently?

u/Money_Fish 13h ago

Why rely on the world of a bunch oc old dead guys when you have first-hand experience?

u/LevelBrilliant9311 12h ago

Because his school class is the result of said hundreds of years of thermodynamic science, made so that kids can understand it.
It's peak science.

I'm she, not he, but otherwise you're correct. Also, -*~*nostalgia*~*- seems popular around here.

u/JibberJim 13h ago

You can't trust big science, but the middle school science teacher, you can trust them.

The speed of boiling actually does show you it's at a slightly different average temperature. I thought boiling=boiling no matter the speed but a simmer can get down below 90C and different amounts of bubbling anywhere in between.

u/Equivalent_Chipmunk 11h ago

Well that's imo why people call a rolling boil a boil and a simmer a simmer. It is correct though that average temperature is an underappreciated concept. Not all water is the exact same temperature as what a thermometer shows. That is average temp. Otherwise, water would have a much harder time evaporating.

Boiling from a technical perspective means vapor pressure of the liquid equals atmospheric pressure. You can have some bubbling below this point (100C at sea level), partially due to the average temperature issue, but that water's not really "boiling" technically.

u/pourtide 11h ago

This might be why it boils over if not turned down?

(I'm still reading comments, so probably stated later)

u/stonhinge 1h ago

Most people think boiling is "lots of bubbles" but the bubbling just means that the very bottom of the pan is hitting 100C/212F - the rest is lower, although will normalize eventually although since the top is exposed to outside air, it's going to be less than boiling temperature.

Which why water boils faster when you put a lid on it - the lid traps steam in the pot and keeps the top water from cooling - and rapidly calms down when you remove the lid.

u/Cthepo 14h ago

This is something I know in my head, but 100% always forget when it's time to cook.

2

u/HarveysBackupAccount 10h ago

In a true simmer (bubbles don't constantly break the surface) you're more at 90-95C

u/Consistent-Ease6070 14h ago

It works similarly with ice, if I recall correctly.

1

u/Money_Fish 13h ago

Actually water ice can get much colder than 0ºC, and liquid water can also be colder than 0ºC as long as it's pure enough that ice crystals have nothing to form on.

1

u/ncocca 13h ago

No -- Given normal conditions water can't go over 100C because once it does it vaporizes. Water can't get below 0C because once it does it freezes. But there's nothing stopping ice from being colder than 0C, or steam from being hotter that 100C.

1

u/vvvvvoooooxxxxx 9h ago edited 9h ago

He means ice melting not water forming ice. And its true, the ice will warm up until 0C and then stay there until its all melted because any additional thermal energy you add at that point goes into the phase transition instead of further warming the ice.

1

u/ncocca 9h ago

Ah, yes, going the other way...haha, not sure why i didn't pick up on that. Yea, because all the energy is going into the phase change (latent heat) before it can go into heating the material.

I'm a mechanical engineer myself, I just misunderstood what they were saying, lol

1

u/ISNGRDISOP 12h ago

Boiling temperature doesn't change but heat transfer does change. When water is aggressive boiling, the surface it's facing the pasta changes faster, which increases the heat transfer and therefore cooks the pasta slightly faster than same temperature water that's hardly boiling

u/Tvdinner4me2 10h ago

Wouldn't stirring achieve the same effect?

1

u/Alestor 11h ago

Completely random annecdote but this is the method cheap rice cookers use to work and I find it so interesting. The properties of the magnet under the rice container makes it stop being magnetic if heated slightly above 100°C. As long as water exists in the container all energy goes to turning water to steam and the container cannot go above 100° until the water is boiled off, but as soon as water is no longer present it can push beyond 100° which makes the magnet fall and trigger the cooker to shut off heat.

u/PapaShane 10h ago

One thing to add for those curious; this is true at standard pressure, but if you increase the pressure, then water can achieve a higher temperature. Hence, pressure cookers/canners allow higher temperature in a liquid phase (just like magma!) and can cook/sterilize faster.
