|— Flavor text • Kirby Star Allies|
When used, Kirby dons a chef's hat and summons a pot in which every regular enemy, enemy projectile, defeated mid-boss and star on-screen is pulled in. He then cooks them all, and then magically turns them all into delicious food which Kirby can eat for replenishing health. This ability can be obtained by eating the mid-boss Chef Kawasaki after he is defeated. In Kirby & The Amazing Mirror, however, he can obtain the ability from either Cookin' or, on rare occasions, Prank.
Cook Kirby's frying pan is also seen in Bomb Rally, a sub-game in Kirby: Nightmare in Dream Land. It serves a similar purpose from the anime. (i.e. knocking projectiles away.) However, this may not be truly considered a use of the ability.
When Kirby uses the ability, all enemies and/or power-ups on the screen are sucked into a giant cauldron, and Kirby bangs his utensils together (a frying pan and a spatula) twice, stirs the pot, and food pops out the top. Defeated mid-bosses will produce two foodstuffs.
Cook returns in Kirby Star Allies. It functions the same as it did in past appearances, except the cauldron attack can be charged, similarly to Crash's Super Nova and Mike's Encore. Chef Kawasaki also appears as both a mid-boss and as the Helper, where he gets a slightly expanded moveset.
(Hold B and release for Kawasaki)
|All enemies, projectiles, and defeated mid-bosses on-screen are sucked into Kirby's or Chef Kawasaki's pot, cooked, and then transformed into food Kirby can use to replenish his health (this move does not work on bosses). If there is nothing to use this move on, the ability will not disappear. Chef Kawasaki must wait for the move to recharge before using it again.|
|Souper Supper||Hold B
(Hold B longer, then release for Kawasaki)
|All enemies, projectiles, and defeated mid-bosses on-screen are sucked into Kirby's or Chef Kawasaki's pot, overcooked, and then shot out out of the pot as soup splashes everywhere, damaging enemies, mid-bosses, and bosses on-screen; like Cook Pot, anything sucked into the pot will drop food and Chef Kawasaki must wait for the move to recharge before using it again.|
|Cook Potluck||Anyone||During Cook Pot, all friends will jump into Kirby's or Chef Kawasaki's pot. They will get cooked, and then they will pop out with extra food that they can use to replenish their health.|
|Supper Party||Anyone||During Souper Supper, all friends will jump into Kirby's or Chef Kawasaki's pot. They will get overcooked and then fly out with extra food, bouncing everywhere around the screen, damaging any enemy they hit.|
Food items obtained from enemies (Kirby Star Allies)
In Kirby Super Star, Kirby & The Amazing Mirror and Kirby Super Star Ultra, regular enemies turn into random food items after being cooked. In Kirby Star Allies, however, each regular enemy (with the exception of boss-exclusive enemies) has food item that corresponds to them. Enemies that can become friends share corresponding food items with their playable versions.
|Apple||Bananas, Cherries, Orange|
|Blade Knight||Green Pepper|
|Bronto Burt||Roast Chicken|
|Chilly||Ice Cream Bar|
|Floaty the Cell Core||Pudding|
|Poppy Bros. Jr.||Baby Bottle|
|Shield Guard||Hotdog (Sizzle), Ice Cream Bar (Blizzard)|
|Waddle Doo||Fried Eggs|
|Yggy Woods' rotten cherries||Cherries|
Food items obtained from Friends
When using Cook's Cook Potluck/Supper Party Friend Ability, certain food items correspond to a Copy Ability and that ability's Helper. This is also true for Dream Friends and when Kirby does not have an ability.
|Adeleine & Ribbon||Rectangular Sandwich|
|Bandana Waddle Dee||Shortcake|
|Dark Meta Knight||Coffee|
|Ice||Ice Cream Bar|
|King Dedede||Roast Chicken|
|Susie||Susie Apple Sherbet|

In Kirby: Right Back at Ya!, Cook is changed into a full-fledged ability with a variety of uses in this version. It's typically acquired from inhaling Kawasaki's frying pan, though other kitchen utensils have often been substituted in lieu of the frying pan not being available for some reason or another.
Cook Kirby's main weapon is a frying pan with many different uses. Often he uses it as a shield, reflecting attacks. However, he can cause it to grow to massive size and use it to fry or boil large enemies. He can also cause any kind of food to spontaneously appear from it.
In the transformation sequence, Kirby spins and forms his hat. Then a frying pan appears from off-screen and flies into Kirby's face, slamming him in the process. Kirby then removes the pan, holds it, and poses dramatically.
In the Super Smash Bros. series
Kirby uses the Cook ability as his Final Smash in Super Smash Bros. Brawl, where its function is largely unchanged from the games, with the exception that everything nearby (items and players, including characters that come out of Assist Trophies and Pokeballs) is sucked into the pot and cooked. After a while, the players and various items are shot out. While powerful (about 24% damage), it has the potential drawback of allowing those hit by the attack to use the items that come out with them. The number of Items produced is about the same number of items put into the pot. In order to counter this the user's best bet is to Inhale as many items as quickly as possible in order to prevent opponents from using them. Kirby's Final Smash can be dodged by using timed movements with invincibility, such as sidesteps and rolls.
The more damage enemies have the harder it is to avoid (i.e. If Kirby uses the Final Smash against an opponent with 200% damage, he/she will be sucked into the pot easier and from a farther distance). It can also suck in enemies through impassable walls, floors, stairs, etc. Players using the Final Smash often find it useful to jump high into the air, then clang the utensils to pull in opponents in a much wider area around them.
In Super Smash Bros. for Nintendo 3DS and Wii U and Super Smash Bros. Ultimate, the Cook Final Smash was replaced with one based off of the Ultra Sword Super Ability that appeared in Kirby's Return to Dream Land.
Cook Kirby gets a trophy as do all the Final Smash attacks. Also, it appears as a sticker in Super Smash Bros. Brawl using its design from Kirby Super Star. The pot has a fork and spoon on it, which it did not have in prior appearances. Applicable by anyone, this sticker increases Flinch Resistance by 140.
|When Kirby needs an energy boost, cook up some "gourmet enemy soup." Cook is a one course meal.|

|“||Kirby in chef's garb. When Kirby throws on his chef's hat, a giant pot appears in the center of the screen. All characters, items, and even long-distance weapons are sucked into the pot. Once they've simmered a bit, food items equal to the number of things in the pot appear. Characters in the mix get blasted straight up out of the pot.”|

|— Kirby Battle Royale - Kirby's 25th Anniversary Copy Ability Poll|
- Cook appears in the cover of the 18th volume of Kirby of the Stars: The Story of Dedede Who Lives in Pupupu, where it also wears a toque.
- Cook is the second most commonly seen Copy Ability in the anime, with seven appearances in total.
- Cook, because it is a one-use ability, is one of the few Copy Abilities in Kirby Super Star, besides the abilities Crash, Paint, Sleep and Mike that can only be obtained through inhaling in the Milky Way Wishes sub-game. Because of that, they are also the only Copy Abilities without Copy Essence Deluxes.
- Cook is the only one-use ability in the series where a Helper can be produced with it. This only applies to its appearance in Kirby Star Allies.
- It is also the only limited-use ability in Kirby Star Allies to have a Copy Essence, due to the fact it has a helper.
- The chef's hat seems to be disproportional for Kirby.
- The ability's keychain from Kirby Super Star Ultra is mistakenly referred to as Chef Kirby in Kirby: Triple Deluxe.
- In promotional artwork for the real-life Kirby Café restaurant chain in Japan, Kirby is depicted with a chef's hat somewhat reminiscent of his appearance while using the Cook ability.
- Cook Kirby's updated appearance in Kirby Star Allies, with the star on the hat, could be inspired by his appearance in Kirby Café.
- In the 25th Anniversary Poll that ran on the Official Kirby Website, Cook was unveiled on November 7, 2017 to have placed in the top ten.
- In Kirby Star Allies, cooking the Dream Friends will always result in a specific food item depending on the Dream Friend cooked.
- Cooking King Dedede produces a roast chicken, Meta Knight and Dark Meta Knight both produce a cup of coffee, Bandana Waddle Dee and Daroach both produce a slice of Strawberry Shortcake (though in Daroach's case, the cake is based on the specific slice seen in Kirby: Squeak Squad), Rick produces a carrot, Marx produces a baguette, and Gooey produces an ice cream cone, and Adeleine produces a sandwich (similar to the type she's seen eating in Kirby 64: The Crystal Shards).
- When using Cook’s Supper Party Friend Ability in Kirby Star Allies, Kirby can be heard quietly singing the short version of the Kirby Dance theme while stirring the pot.
