This Outland Cooking leveling guide will show you the fastest way how to level your Outland Cooking skill up from 1 to 75 as inexpensively as possible.
Often the materials are based on a case that you will gain one skill point each craft. This won't happen, so you will have to buy a few extra materials while you are leveling your Outland Cooking.
Leveling Outland Cooking
Go to Outland and find Allison (Horde) or Gaston (Alliance) in Hellfire Peninsula, then learn Outland Cooking.
You can also learn it from Jack Trapper in Shattrath City but you will have to go to Hellfire Peninsula to buy the recipes anyway.

60 x 
[Mok'Nathal Shortribs] - 60 x 
[Raptor Ribs]
Recipe location:
-
Horde: You can buy both recipes from Xerintha Ravenoak in Blade's Edge Mountains at Ruuan Weald. She sells these in limited supply, so you have to wait if someone bought them before you. If they are not in stock, you should get them from completing the 
Mok'Nathal Treats quest, because it's probably faster than waiting. (I don't know how often she restock the recipes) -
Alliance: You can buy them from Sassa Weldwell in Blade's Edge Mountains at Toshley's Station. (She sells the recipes in unlimited quantity, so Alliance players should always buy them from her)
I hope you liked this Outland Cooking leveling guide, congratulations on reaching 75!
