Minced Onion to Fresh Onion Conversion: Exact Ratios for Small, Medium & Large Onions

When substituting minced onion for fresh, the exact conversion depends on onion size: 3 tablespoons of jarred minced onion equals one small onion, 4-5 tablespoons for a medium onion, and 6-7 tablespoons for a large onion. This guide provides precise measurements, storage tips, and expert advice for perfect cooking results every time.

Onion Size	Jarred Minced Onion	Dried Minced Onion	Fresh Chopped Onion
Small (3 oz / 85g)	3 tbsp	1 tbsp	¾ cup
Medium (4.5 oz / 128g)	4–5 tbsp	1½ tbsp	1 cup
Large (6 oz / 170g)	6–7 tbsp	2 tbsp	1¼ cups

Why This Conversion Matters

Getting the right onion measurement is crucial for flavor balance in soups, stews, salsas, and marinades. Too little onion lacks depth; too much overwhelms other ingredients. Consistent conversions ensure reliable results.

Frequently Asked Questions

How much jarred minced onion equals one medium onion?

Approximately 4-5 tablespoons (¼ to ⅓ cup) of jarred minced onion equals one medium onion (4.5 oz / 128g). This is equivalent to about 1 cup of freshly chopped onion.

Dried minced onion is more concentrated. For one medium onion, use 1½ tablespoons. Rehydrate with warm water before use for best results.

Yes for cooked dishes like soups and stews, but avoid for raw applications like salsas where fresh onion's crisp texture matters.

Practical Measuring Tips

Use measuring spoons for consistency; drain excess liquid from jarred onion before measuring.
1 small onion ≈ ¾ cup chopped, 1 medium ≈ 1 cup chopped, 1 large ≈ 1¼ cups chopped.
