Ingredients
  

  • ¼ cup dried onion flakes
  • 2 tablespoons sodium-free beef bouillon granules
  • ¼ teaspoon onion powder
  • ¼ teaspoon parsley flakes
  • ⅛ teaspoon celery seed
  • ⅛ teaspoon paprika
  • ⅛ teaspoon ground black pepper

Equipment

  • Non-stick skillet
  • Small mixing bowl or jar
  • Airtight container

Method
 

  1. Place the dried onion flakes into a dry, non-stick skillet over medium-low heat. Toast them for 1 to 2 minutes, stirring or tossing constantly, until they reach a light golden-brown color and smell nutty.
  2. Remove the toasted flakes from the heat and allow them to cool for a minute. Measure the beef bouillon granules, onion powder, parsley, celery seed, paprika, and black pepper into a small bowl or glass jar.
  3. Stir the ingredients thoroughly to combine. If using a jar, seal the lid tightly and shake vigorously for 30 seconds to ensure the spices are evenly distributed.
  4. Store the finished mix in an airtight container in a cool, dark place. Use 3 tablespoons to replace one standard store-bought packet in any recipe.

Notes

Pro Tip: For the best texture and aroma, grind the celery seeds with a mortar and pestle before adding them to the mix to prevent a gritty mouthfeel.
Storage Tip: Always shake your storage container before measuring out the mix, as the heavier bouillon granules naturally settle at the bottom over time.
Troubleshooting Tip: If you find the flavor of your dip has a metallic edge, it may be the brand of bouillon. Add a tiny pinch of sugar or extra onion powder to balance the profile.
