Slow Cooker Conversion Chart

Turn a conventional recipe's oven or stovetop time into a slow cooker Low or High setting.

Original recipe timeSlow cooker LowSlow cooker High
15–30 minutes4–6 hours1.5–2.5 hours
35–45 minutes6–8 hours3–4 hours
50 minutes – 3 hours8–10 hours4–6 hours

Find the row matching the original recipe's cook time, then use whichever column matches the setting you plan to use.

Why this is a lookup table, not a clean formula

The relationship between conventional cooking time and slow cooker time isn't a simple linear multiplier — a slow cooker's Low setting runs around 190–200°F and High around 250–300°F, both well below a conventional oven or stovetop simmer, so the conversion depends more on which time bracket the original recipe falls into than a single consistent ratio across all cook times.

Low and High reach the same doneness, just on different schedules

Both settings are designed to get food to the same safe, fully-cooked endpoint — Low just takes longer at a gentler temperature, which tends to be more forgiving for tougher cuts of meat that benefit from a long, slow break-down of connective tissue. High is the better choice when you need dinner sooner and the dish doesn't especially benefit from the extra hours.

Don't just multiply everything by 4

Because the extremes of the table (short original times vs. long ones) scale differently, applying one flat multiplier across every recipe over- or under-shoots depending on where the original time falls — use the actual bracket in the table above rather than assuming a single multiplier applies universally.
