Timing table for common oven scenarios
Use this table as a practical baseline, then validate in the center of the product.
| Scenario | Oven temp | Time range | Doneness check |
|---|---|---|---|
| Open tray / default | 245°C / 473°F | 12-18 min | Verify at least 63°C / 145°F. |
| Covered / foil | 245°C / 473°F | 14-21 min | Expect softer texture. |

| From frozen start | 245°C / 473°F | 17-26 min | Keep spacing and avoid crowding. |
Safety vs doneness
Safety baseline
Safe minimum reference: 63°C / 145°F in the center.
Texture / doneness target
Texture preference can be set to: safe minimum, juicy, well done. This target can be above the safety minimum.

FAQs
How long should I cook london broil?+
A practical base range is 12-18 min at about 245°C / 473°F. Start checks early if your piece is thinner or your batch is smaller than average.
Why is the result always a range?+
Because timing shifts with thickness, broiler distance, and marinade, oven behavior, and setup details like convection, cover, or tray crowding.
How should I separate safety from doneness preference?+
Safe minimum reference: 63°C / 145°F in the center. Doneness and texture may require extra time beyond the minimum.
What should I focus on for this page?+
Use practical oven ranges, then verify doneness in the center instead of trusting one exact minute.
