Equipment

  • Small skillet
  • Small mixing bowl
  • Airtight glass jar

Ingredients
 

  • 1/4 cup dried onion flakes
  • 2 tablespoons low-sodium beef bouillon granules
  • 1/4 teaspoon onion powder
  • 1/4 teaspoon parsley flakes
  • 1/8 teaspoon celery seed
  • 1/8 teaspoon paprika
  • 1/8 teaspoon ground black pepper

Instructions
 

Prep your base

  • Set a small dry skillet over medium heat, then add the dried onion flakes. Stir constantly for about 60 seconds, just until they smell sweet and toasted and look slightly more golden, not dark brown.
  • Slide the toasted flakes onto a plate to cool for a minute. This keeps the flavor bright and prevents any carryover heat from pushing them into bitter territory.

Blend the mix

  • In a small bowl, combine the toasted onion flakes with the beef bouillon granules, onion powder, parsley flakes, celery seed, paprika, and ground black pepper.
  • Stir until the colors look evenly speckled throughout. If you added nutritional yeast, make sure you don’t see any pale clumps, it should disappear into the blend.

Jar it up

  • Pour the mix into an airtight glass jar and label it. This batch replaces one 1-ounce envelope of commercial dry onion soup mix. Use 3 tablespoons as a standard measurement.

Notes

Storage Tip: Keep your mix in a lidded glass jar and shake it before each use, as bouillon granules tend to settle at the bottom over time. Use within six months for the best flavor.
Sodium Sensitivity: If you are monitoring salt intake, use sodium-free bouillon granules and add salt to your final dish to taste.
Flavor Secret: For extra umami depth, add 1/2 teaspoon of nutritional yeast. It adds a savory, rounded finish without tasting like cheese.
