For one small onion, use about 2 teaspoons of onion powder as a substitute.

Quick Scoop

  • A small onion (about ½ cup chopped) ≈ 2 teaspoons onion powder.
  • Onion powder is more concentrated, so start with a bit less if you’re unsure and taste as you go.
  • You can always add more powder, but you can’t take it out once it’s in.

How to Use This in a Recipe

  1. Check your recipe: If it says “1 small onion, finely chopped,” replace it with 2 teaspoons onion powder mixed into the wet ingredients (broth, sauce, etc.) so it disperses evenly.
  1. Taste test: After cooking a few minutes, taste and, if you want a stronger onion flavor, add up to an extra ½ teaspoon at a time.
  1. Mind the texture: Onion powder adds flavor but not the bite or moisture of fresh onion, so dishes like salads or salsas may feel a bit different.

Little Kitchen Story

Imagine you’re halfway through a cozy weeknight stew, onions completely forgotten until you open the fridge and realize… none left. You stir in 2 teaspoons of onion powder instead, let it simmer, and the aroma slowly deepens. The stew won’t have little onion pieces floating in it, but the flavor still lands warm and savory, and nobody at the table ever guesses you were out of fresh onions.

TL;DR: 1 small onion ≈ 2 teaspoons onion powder, then adjust to taste.
