Slow Cooker Time from Oven Recipe Calculator

Slow-cooker low: 6-7 h per 30 min oven; high: 3-4 h per 30 min.

Convert a conventional oven recipe time to the equivalent slow-cooker time. Rule of thumb: 30 min in a 350 °F oven ≈ 6.5 h on Low or 3.5 h on High. The calculator scales the user-entered oven time to both Low and High settings using the user-chosen multipliers.
