Your recipe calls for 3 T minced garlic and you only have garlic powder How much do you use?

To substitute garlic powder for minced garlic, the general rule is to use about 1/8 teaspoon of garlic powder for every clove of garlic, which translates to roughly 1 teaspoon of garlic powder for 1 tablespoon of minced garlic. Since you need 3 tablespoons of minced garlic, you would use about 3 teaspoons of garlic powder, or 1 tablespoon. Adjust according to your taste preference, as garlic powder can have a different flavor intensity.
