Dried minced onion is more than half this blend by volume, with beef bouillon granules and onion powder making up most of the rest. One batch, 5 tablespoons, is what Taste of Home uses for a pot of onion soup with 4 cups of water, or for onion dip with 2 cups of sour cream.

Bouillon brands vary in how salty they are, so check your label before adding more salt to a finished dish.

Classic Onion Soup Mix from Taste of Home, scaled with the site's kitchen rounding. Weights from USDA FoodData Central where USDA lists the exact form.

How the scaling works

Classic Onion Soup Mix totals 1 1/4 cups + 1 1/2 tbsp as published, across 5 ingredients. Every one is multiplied by the same number, so dried minced onion stays 56% of the blend whatever size you make. Pick a multiplier directly, or enter the amount you want and the calculator works back to it from that 1 1/4 cups + 1 1/2 tbsp total.

Amounts under 3 teaspoons round to the nearest 1/8 teaspoon, and larger amounts round to the nearest 1/4 teaspoon in tablespoons.

Worked example: doubling the base recipe

Ingredient	Base	x 2
dried minced onion	3/4 cup	1 1/2 cups
beef bouillon granules	1/3 cup	1/2 cup + 2 1/2 tbsp
onion powder	1/4 cup	1/2 cup
sugar	1/4 teaspoon	1/2 tsp
celery seed	1/4 teaspoon	1/2 tsp

How this was checked

This recipe is Taste of Home's Classic Onion Soup Mix, created by June Mullins and tested by the Taste of Home Test Kitchen. Cedrick Reese checked the amounts against Taste of Home's own recipe page for Ready Utilities. Dried minced onion and beef bouillon granules show no gram weight because USDA FoodData Central only lists dehydrated onion flakes, a different cut, and bouillon brands vary too much to assign one weight. There's no plain salt ingredient in this recipe, so there's no salt selector; the bouillon carries the blend's saltiness instead.
