- Add the stock and pan drippings and bring to a boil.
- Simmer over low heat for about 10 minutes until the vegetables are tender and the liquid is reduced by about 1/3.

Notes
This au jus can be made up to 2 days ahead and stored in the refrigerator. It can be stored in the refrigerator for 6 to 7 days or frozen for up to 6 months. To reheat, add the desired amount to a saucepot and cook over low heat until hot. Any yellow, sweet, or white onion will work, as well as shallots. Cool pan drippings quickly to solidify and separate fat for finishing the au jus. Finishing a sauce with chilled fat is called "monter.".
