How do I convert oven time to slow cooker time?

As a guide, a dish that takes 15–30 minutes conventionally needs about 4–6 hours on Low or 1.5–2 hours on High; 30–45 minutes becomes 6–8 hours Low or 3–4 hours High; longer braises become 8–12 hours Low or 4–6 hours High.

What is the difference between Low and High?

Both settings reach a similar simmering temperature, but High gets there faster. Low takes roughly twice as long as High, which is better for tougher cuts that benefit from a long, gentle cook.

How long does 45 minutes in the oven take in a slow cooker?

A dish around the 45-minute mark converts to roughly 8 to 12 hours on Low or 4 to 6 hours on High, depending on the cut and how full the pot is.

Should I reduce the liquid for slow cooking?

Usually yes. Slow cookers lose very little moisture because the lid stays on, so recipes adapted from the oven often need around a third less liquid to avoid a watery result.

Can I leave a slow cooker on all day?

Slow cookers are designed for long unattended cooking, and the Low setting in particular is meant for 8 hours or more. Always follow your appliance's instructions and keep the lid on.

Slow Cooker Time Converter

Convert cooking time to a slow cooker

Slow cookers turn a quick oven or stovetop dish into a long, hands-off braise. This tool converts a conventional cooking time into the equivalent slow cooker time on Low or High — for home cooks adapting a recipe to a crock pot.

How it works

The converter maps the conventional time into one of three bands and returns the recommended slow cooker range. Low runs roughly twice as long as High, since both reach a similar simmer but High gets there faster:

Conventional time	Slow Low	Slow High
Up to 30 min	4–6 hours	1.5–2 hours
30–45 min	6–8 hours	3–4 hours
45 min and over	8–12 hours	4–6 hours

Example

A casserole that takes about 45 minutes in the oven converts to roughly 8–12 hours on Low or 4–6 hours on High. Choose Low for tougher cuts that benefit from a long, gentle cook.

Resist lifting the lid — every peek lets heat escape and can add 20–30 minutes to the cook. All conversions happen locally in your browser, with nothing uploaded.
