How It Works
A slow cooker on Low runs at about 200°F (93°C) and on High at about 300°F (149°C). The general conversion rule: Low 8 hours = High 4 hours = Oven at 325°F for 2-3 hours. This calculator applies that ratio to any time you enter and also shows Dutch oven equivalents.
- Choose your conversion direction — slow cooker to oven, or oven to slow cooker.
- Enter the original settings (time and temperature/setting).
- Get converted times for conventional oven, Dutch oven, and the alternate slow cooker setting.
Dutch ovens cook slightly slower than a standard baking dish because cast iron distributes heat more evenly and the heavy lid traps moisture. The calculator adds about 15% to the oven time for Dutch oven estimates.

| Slow Cooker (Low) | Slow Cooker (High) | Oven (325°F) | Dutch Oven (300°F) |
|---|---|---|---|
| 4 hours | 2 hours | 45 min - 1h 15m | 1 - 1.5 hours |
| 6 hours | 3 hours | 1.5 - 2 hours | 1.75 - 2.5 hours |
| 8 hours | 4 hours | 2 - 3 hours | 2.5 - 3.5 hours |
| 10 hours | 5-6 hours | 3 - 4 hours | 3.5 - 4.5 hours |
| 12 hours | 6-7 hours | 3.5 - 5 hours | 4 - 5.5 hours |
What Works in a Slow Cooker vs. Oven
Not every recipe converts well between methods. Here is a quick guide to what works and what to avoid.
| Works Well | Does Not Convert Well |
|---|---|
| Pot roast, stews, braises | Crispy-skin chicken or turkey |
| Soups and chili | Fried or breaded foods |
| Pulled pork and shredded chicken | Steaks or chops (overcook easily) |
| Beans and lentils | Baked goods (cakes, bread) |
| Curries and sauces | Pasta (gets mushy in slow cooker) |
| Meatballs in sauce | Stir-fries (need high heat) |
The slow cooker is best for tough, cheap cuts that benefit from long, low-temperature cooking: chuck roast, pork shoulder, short ribs, and bone-in thighs. Tender cuts like chicken breast or fish can be slow cooked, but they must be added later in the cook — otherwise they turn dry and stringy.
FAQ
Can I convert any slow cooker recipe to the oven?
Most braised and stewed recipes convert well. The main difference is that ovens evaporate more liquid since slow cookers trap steam with a tight lid. When converting to the oven, reduce the liquid by about 25% or keep the lid on for most of the cook time.
Is a Dutch oven the same as a slow cooker?
Not exactly. A Dutch oven is a heavy pot (usually cast iron or enameled cast iron) used inside a conventional oven. It produces similar results to a slow cooker — moist, tender braises — but at a higher temperature and shorter time. Dutch ovens also let you sear meat on the stovetop before braising, which builds more flavor.
Why do slow cooker recipes take so long?
Slow cookers operate at low temperatures (200-300°F) and rely on time to break down collagen in tough cuts of meat. The low heat means the food never reaches a hard boil, which is why braised meats come out tender instead of tough. Raising the temperature too high defeats the purpose.
Can I leave a slow cooker on overnight?
Yes. Slow cookers are designed for unattended cooking. The outer housing stays cool, and the low setting is under 200°F — well below the ignition point of any food. Make sure the cord is away from water and the cooker sits on a heat-resistant surface.
