How long can a cooked roast sit in turned off oven?

It's generally not recommended to leave cooked roast in a turned-off oven for an extended period. Here's why:

* Food Safety: The temperature inside a turned-off oven will gradually cool down, but it may still be in the "danger zone" (40°F to 140°F) for a significant amount of time, allowing bacteria to multiply.

* Moisture Loss: Even in a turned-off oven, the roast will continue to dry out as it cools.

Here's a better approach:

1. Rest the roast: Let the roast rest, covered with aluminum foil, for 15-20 minutes after cooking. This allows the juices to redistribute, making for a more tender and flavorful cut.

2. Refrigerate promptly: After resting, refrigerate the roast as soon as possible. It's generally safe to refrigerate cooked roast for up to 3-4 days.

If you absolutely must leave the roast in the oven:

* Keep it warm: Leave the oven door slightly ajar to allow some heat to escape, but keep the roast above 140°F.

* Don't leave it too long: The maximum time you should leave it in the oven is 2 hours.

Always prioritize food safety and err on the side of caution. If you're unsure, it's best to refrigerate the roast as soon as possible.
