Yes, you can grate onions.
Grated onion is a useful ingredient in cooking, providing a finely textured result that cooks quickly and blends easily into sauces, dressings, and other dishes. Grating is an efficient way to achieve a very fine mince or a paste-like consistency, much finer than can be achieved by chopping or dicing.
Here's some information on grating onions:
-
Why grate onions? Grating raw onions creates tiny pieces ideal for dishes where you want the onion flavor to be dispersed throughout, without noticeable chunks. This is helpful in certain sauces, dips, or marinades.
-
How to grate onions: Peel the onion and cut it in half. Hold one half firmly and rub it against the large holes of a box grater, working down to the root end. Be careful to avoid grating your fingers at the end.

Uses for grated onions:
- Sauces and gravies: Grated onion adds flavor and thickness.
- Meatballs and meatloaf: Helps bind the ingredients and add moisture.
- Salad dressings: Creates a smooth, well-integrated flavor.
- Dips: Provides a uniform texture and consistent onion flavor.
- Marinades: Ensures thorough flavor penetration.
-
Considerations: Grating onions releases more of their volatile compounds, which can cause more tears than chopping. Using a food processor with a grating attachment can minimize this effect.
