Ingredients Method Notes

Ingredients
  

  • 1 Dried Minced Onion (rehydrated) 1:1 ratio by volume; best for batters and doughs
  • 1 Onion Powder 1:1 ratio by volume; best for dry rubs and smooth sauces
  • 1 Leek Powder or Shallot Flakes 1:1 ratio by volume; best for savory pastries and spice blends
  • 1 Garlic Powder + Onion Powder Blend 2:1 garlic to onion ratio; best for dry seasoning and spice rubs
  • 1 Fresh Onion, Finely Minced 1:1 ratio by weight; best for cooked dishes and bread doughs

Method
 

  1. Choose your substitute based on the dish type and desired flavor match. Consider whether texture, moisture, or pure flavor is the priority.
  2. Prepare the substitute as directed: rehydrate dried minced onion in warm water for 5 minutes, blend garlic and onion powder at a 2:1 ratio, or finely mince fresh onion before measuring by weight.
  3. Apply the substitution ratio carefully. Use 1:1 by volume for dried minced onion, onion powder, leek powder, and shallot flakes. Use 1:1 by weight for fresh minced onion.
  4. Taste and adjust seasoning. Fresh onion adds moisture so reduce other liquids or increase flour slightly. Garlic-forward blends may need a pinch of paprika to balance sweetness and color.

Notes

  • Onion powder is more potent by weight than flakes; taste as you go rather than adding the full amount at once.
  • Fresh minced onion is roughly 89% water; always adjust dry ingredients when using it in baked goods.
