When a recipe calls for onion soup mix, what can I substitute?

For every ¼ cup of onion soup mix in a recipe, you can combine 3 tablespoons of minced onion flakes, 2 tablespoons of beef bouillon powder, ½ teaspoon onion powder, ¼ teaspoon parsley flakes, 1/8 teaspoon ground celery seeds, and a pinch each of black pepper, sweet paprika, and salt.

You'll often see onion soup mix called for in pot roast recipes and onion dip recipes, and this substitution will work fine in those types of recipes.
