 Once the pressure has been reached, cook the onions for 15 minutes. Each pressure cooker is different. Some have a continuous sound while others have a whistle go off every few seconds.

Use the cubes for other dishes that call for onion flavor. This can include other stews, chiles, and soups.
Freeze a 2-3 pound bag of onions for 15 minutes.
Peel the onions.
