A guide — slow cookers vary. Reduce liquid, keep the lid on, and check meat reaches a safe internal temperature.

Low and slow, from any recipe

A slow cooker swaps a short blast of high heat for hours of gentle warmth. Converting a conventional time means stretching it out — a lot on the Low setting, somewhat less on High, which runs hotter.

Low ≈ 8–12× the conventional time　·　High ≈ 4–6×

The ranges reflect how much dishes and cookers differ. Pick the longer end for tougher cuts and bigger quantities, and the shorter end for tender ingredients you do not want to overcook.

Worked example

A dish that takes about 30 minutes in a conventional oven translates to roughly 4–6 hours on Low, or about 2–3 hours on High, in a slow cooker.

Getting the best from it

Slow cookers shine with stews, braises and tough cuts that reward long, moist cooking. Because almost no liquid escapes, trim the amount you add, and resist lifting the lid — every peek sets the clock back.

Cook’s notes

Less liquid. Cut roughly a third versus the oven version.
Lid stays on. Peeking adds 15–20 minutes each time.
Mind food safety. Thaw frozen food first; cook meat to a safe temperature.

Frequently asked questions

How do the times relate?

As a rough guide, Low is about 8–12 times the conventional time and High about 4–6 times. High roughly halves the Low time, since it runs hotter.

Should I reduce the liquid?

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

Why not lift the lid to check?

Each peek lets out heat and steam and can add 15–20 minutes to the cook. Resist checking until near the end of the estimated time.

Is it safe to cook from frozen?

It is generally not recommended — food spends too long in the temperature range where bacteria grow. Thaw first, and make sure meat reaches a safe internal temperature.
