Kill Ravagers and Wolves around Duskwood for Lean wolf Flank.
You'll need about 50-60 (including the ones you need for quest).N.B. you could get the Lean Wolf Steak recipe from Super Seller 680 in Desolace and continue killing until your cooking is up to 150+ and then skip the next step, but it’s a limited supply recipe and can be annoying to get).

130 to 175
Curiously Tasty Omelet (1 x Raptor Egg, 1 x Hot Spice) x 50
To Train as a Expert cook, go to Shandrina by Mystral Lake in Ashenvale and buy the Expert cookbook.
Go to Kendor Kabonka in Stormwind City and buy the Curiously Tasty Omelet recipe.

Go see Corporal Bluth at the Rebel Camp in Stranglethorn Vale and buy the Roast Raptor recipe (remembering to pick up about 40 hot spices on the way). Cook all the Raptor Meat you got from Arathi Highland Raptors and then go kill Jungle Stalkers near the Gurabashi Arena until you have enough to take you to level 200 cooking.

200 to 225
Spider Sausage (2 x White Spider Meat) x 30
Kill Darkfangs around Dustwallow Marsh for White Spider Meat. *You may want to keep killing Raptors as it can work out quicker. Just depends on your luck.

225
It’s cooking quest time.
Go to Gadgetzan and speak to Dirge Quikcleave to obtain Artisan cooking quest - Clamlette Surprise (he's in the tavern). Whilst your here, pick up the Tender Wolf Steaks recipe.
You'll need 12 Giant Eggs, 10 Zesty Clam Meat and 20 Alterac Swiss. The Alterac Swiss is the easiest to get, just go to the Trade District in Stormwind City and buy it from Ben Trias. Get the eggs from the Owlbeasts in The Hinterlands (the drop rate is way better than the Rocs in Tanaris). For the clam meat go to Steamwheedle Port in Tanaris and kill the Turtles. They will drop Big Mouth Clams at a good rate, which contain Zesty Clam Meat.
Keep killing Owlbeasts in The Hinterlands and grab another 70-80 eggs. Also kill the Wolves round here for Tender Wolf Meat. Go to Talonbranch Glade in Felwood and buy the Monster Omelet recipe from Malygen and about 140-160 Soothing Spices.

225 to 275
Monster Omelet (1 x Giant Egg, 2 x Soothing Spices) x 80
or
Tender Wolf Steaks (1 x Tender Wolf Meat, 1 x Soothing Spice) x 80

For some reason, Blizzard decided it was too easy to get from 250 to 285, so therefore they stopped players being able to cook Omelets and Steaks for skill ups beyond 275. So your going to have to go to Dire Maul and kill a boss for Runn Tum Tuber Surprise recipe.

275-285
Runn Tum Tuber Surprise (1 x Runn Tum Tuber, 1 x Soothing Spice) x 10
You will have to go to Dire Maul East and kill the little Imp boss, Pusillin to get the recipe for these. It's a 100% drop rate (ignore Thottbot) if you haven't got the recipe, but he will only drop one copy. So if there are more than one of you that needs it, you will have to kill him again for it each time.
At level 70, all classes can do this boss and can avoid nearly all mobs on the chase towards the final confrontation. Just take some health/mana pots with you.

285 to 300
Smoked Desert Dumplings (1 x Sandworm Meat, 1 x Soothing Spice) x 20.
Go to Cenarion Hold in Silithus and speak to Calandrath for the Desert Recipe chain of quests. When you get to the third quest you'll get the recipe for Smoked Desert Dumplings. Kill Dredge Crushers and Strikers for the Sandworm Meat (low drop rate). You'll need about 10 more than the quest needs plus the soothing spices (20 in total).

Cooking 300 to 375 Guide by Highlander on EU-Terenas

First you need to learn Master Cooking, so go see Gaston in Honor Hold and buy the Master Cooking Manual.

300 to 325
Buy the recipe for Ravager Dogs from Sid Limbardi in Honor Hold and then go kill Ravagers around Falcon Watch until you have about 35-40 meat.

325 to 350
Two choices here.
1). Go buy the Roasted Clefthoof recipe from Uriku in Telaar (Nagrand) and then kill Clefthoofs around Nagrand for about 35-40 meat or:
2). Go buy the Warp Burger recipe from Supply Officer Mills in Allerian Stronghold (Terokkar Forest) and then kill Warp Stalkers/Hunters around Terokkar Forest for about 35-40 meat.

350 to 375
This part really is a problem at the moment. The best way to get to 375 at the moment is by fishing up Furious Crawdads in one of three lakes around Terokkar Forest and then cooking them. However, these lakes are only accessible if you have a flying mount.
The three lakes are:
Lake Jorune - north west of Stonebreaker Hold.
Lake Ere'Noru - south east of Allerian Stronghold.
Blackwind Lake - in the south east corner of the map, in the Skettis area.
You can buy the recipe from Innkeeper Biribi in Allerian Stronghold.
However, you can go to Toshley's Station in Blade's Edge Mountains and find an NPC called Sassa Weldwell. She will sell you the recipes for Crunchy Serpent and Mok'nathal Treats. These stay green until 375. You can now kill Scalewing's and Raptors around Blade's Edge Mountains for Serpent Flesh and Raptor Ribs. You will need about 60 to get to 375.

*Blizzard added recipes for Hot Buttered Trout and Fisherman's Feast. Both of which stay orange till 375. Unfortunately the main component is so far harder to fish up than Crawdads. Hopefully this will change. But if you get any Enormous Barbed Gill Trout or Huge Spotted Fetail then cook them. The recipes are taught by the barmaid in the World's End Tavern in Shattrath City.
