How to convert recipes to a slow cooker
Slow cookers heat food gently over many hours: on LOW they typically reach about 200 °F (93 °C) in the crock, and on HIGH about 300 °F (149 °C) at the base. Converting a recipe means two adjustments – more time and less liquid, because the lid traps moisture and very little evaporates.
| Oven / stovetop time | Slow cooker LOW | Slow cooker HIGH |
|---|
| 15 – 30 min | 4 – 6 h | 1.5 – 2.5 h |
| 30 min – 1 h | 5 – 7 h | 2.5 – 3.5 h |
| 1 – 3 h | 8 – 10 h | 4 – 6 h |
| over 3 h | 10 – 12 h | 5 – 7 h |
As a rule, one hour on HIGH equals about two hours on LOW. Tough, collagen-rich cuts such as chuck, brisket and pork shoulder benefit most from long, low cooking.
Reduce the liquid
Cut the liquid in oven and stovetop recipes by about a third to a half, unless you're making soup. Vegetables and meat release their own juices. If the sauce is too thin at the end, remove the lid for the last 30 – 60 minutes on HIGH or thicken with a cornstarch slurry.
Choosing a slow cooker size
| Size | Serves | Good for |
|---|
| 1.5 – 3 qt | 1 – 2 | Dips, sides, small meals |
| 4 – 5 qt | 3 – 4 | Everyday family meals |
| 6 – 7 qt | 5 – 7 | Roasts, whole chickens, batch cooking |
| 8 qt + | 8 + | Large families, parties, meal prep |
Useful features include a programmable timer that switches to WARM, an oval crock for roasts, a removable stovetop-safe insert for browning, and a locking lid for transport.
Food safety
- Thaw meat and poultry before slow cooking (USDA).
- Keep the lid on – each peek adds 15 – 20 minutes of cooking time.
- Check meat with a thermometer: 165 °F for poultry, 145 °F + rest for whole cuts of beef and pork, 160 °F for ground meat.
- Boil dried red kidney beans for 10 minutes before slow cooking.
- Refrigerate leftovers within two hours – don't cool food in the crock.
Energy use
Slow cookers draw only about 150 – 300 W and cycle on and off, so an 8-hour cook uses around 1 – 1.5 kWh – comparable to or less than an hour of oven use, and it doesn't heat up your kitchen.
Frequently asked questions
How do I convert oven time to slow cooker time?
A 1 – 3 hour oven recipe typically takes 8 – 10 hours on LOW or 4 – 6 hours on HIGH.
Is 1 hour on high equal to 2 hours on low?
Roughly, yes. LOW takes about twice as long as HIGH to reach the same result.
How much should I reduce liquid for a slow cooker?
By about a third to a half for most oven and stovetop recipes, except soups.
What size slow cooker for a family of four?
A 5 – 6 quart cooker is the most versatile size for four people with leftovers.
Can I put frozen meat in a slow cooker?
USDA recommends thawing meat first so it heats quickly through the bacterial danger zone.
About LowHigh
LowHigh is an independent, free conversion calculator for slow cookers based on widely published manufacturer guidance and USDA food-safety advice. Check meat with a thermometer. We are not affiliated with any appliance brand.
Every formula on this page runs entirely in your web browser. The numbers you type are never uploaded, stored or shared. Our goal is simple: give you an honest starting point so you can compare product specifications with confidence and avoid paying for capacity you do not need – or buying something too small to do the job.
The methodology combines widely published engineering rules of thumb, manufacturer data sheets and the electrical code practices that installers use every day. We review the assumptions regularly and update the calculator when typical product specifications change.
