I’ll let you know the types of things you can craft in each category and the benefits they give. Check out my Weapon or Armor guides for more crafting tips.

This guide will go over cooking and chem crafting in Fallout 4 including:

  • Cooking and Chem Crafting Basics – How to craft in these categories, and some helpful perks.
  • Advanced Cooking Info – A list of all the cooking recipes and the materials needed.
  • Advanced Chemistry Info – Each category and types of things you can craft in each.

Cooking and Chem Crafting Basics

Cooking is the easiest of the craft because it does not require any perks. All you need to cook is compatible food. These can be crops, meats, drinks, or parts from creatures. 

Chems take more effort and resources to craft, and some require certain perks. Most random things you find throughout the world can be broken down into materials and components to use for Chem crafting.

You must go to a Cooking Station to cook anything and a Chemistry Station to craft Chems. You can find these throughout the world, or at settlements. You also get experience for everything you craft.


Some perks are required to make certain Chems, while others are helpful when using chems.
