Pressure Cooker French Onion Soup Recipe
Instructions
Prep:15minCook:1h 15min
Traditional techniques for caramelizing onions can take hours to deliver extra-sweet, complex flavor. The pressure cooker reduces that time down to about 30 minutes of hands-off cooking. Finishing off those onions with sherry, stock, and some aromatics transforms them into a soul-satisfying classic French onion soup.
