How to Use These Substitutes Like a Pro

Fresh Minced Onions

Use 1/4 cup minced fresh onion for every tablespoon of onion powder. Sauté first to remove moisture for dry recipes. Yellow onions give stronger flavor; Vidalia for milder taste.

Garlic Powder

Use half the amount of garlic powder compared to onion powder. Ideal for recipes already containing garlic. Best for rubs and roasted vegetables.

Shallot Powder

Use 1:1 ratio. Add at the end of cooking to preserve delicate flavor. Perfect for sauces and seafood dishes.

Leek Powder

Use 1:1 ratio. Ideal for creamy soups, scalloped potatoes, and herb-seasoned rice. Blends seamlessly into dairy-based dishes.

Onion Salt

Replace 1 tablespoon onion powder with 1 teaspoon onion salt. Reduce other salt in the recipe by 3/4 teaspoon to avoid over-salting. Great for snacks and grilling.
