How It Works
Slow cookers use low, steady heat over long periods to tenderize meats and meld flavors. Converting from oven to slow cooker follows general time guidelines based on oven temperature.
The basic rule:
- Oven at 325–350°F → Slow Cooker on Low 8–10 hrs or High 4–5 hrs
- Oven at 375–400°F → Slow Cooker on Low 6–8 hrs or High 3–4 hrs
- Reduce liquids by about one-third — slow cookers retain moisture
These conversions work for most braised meats, stews, soups, and casseroles. Avoid slow-cooking dairy, pasta, and delicate vegetables for the full time — add those in the last 30–60 minutes.
Tips & Considerations
- Double-check your oven temperature before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both slow cooker on low and slow cooker on high — they work together to give you the full picture.

Frequently Asked Questions
How do I convert an oven recipe to slow cooker?
Use the oven temperature as a guide. Recipes at 325-350°F typically need 8-10 hours on Low or 4-5 hours on High. Recipes at 375-400°F need 6-8 hours on Low or 3-4 hours on High. Reduce liquid by about one-third since slow cookers retain moisture.
What temperature is Low and High on a slow cooker?
Low is approximately 190°F (88°C) and High is approximately 300°F (149°C). Both settings eventually reach the same temperature — the difference is how quickly they get there. Low takes longer to reach the simmer point.
Can I convert any oven recipe to slow cooker?
Most braised meats, stews, soups, chilis, and casseroles convert well. Recipes that require browning, crisping, or high dry heat (like roasted vegetables or baked goods) do not work well in a slow cooker without modifications.
Should I reduce liquid when converting to slow cooker?
Yes, reduce liquid by about one-third. Slow cookers trap steam under the lid, so very little moisture evaporates. If you use the same amount of liquid as an oven recipe, your dish may turn out watery.
Is it better to cook on Low or High?
Low is generally better for tougher cuts of meat because the longer cooking time breaks down connective tissue more effectively. High works well when you're short on time, but the texture may not be quite as tender for meats like pot roast or brisket.
Can I leave a slow cooker on overnight?
Yes, slow cookers are designed for unattended cooking and are safe to leave on overnight or while you're away. Use the Low setting for overnight cooking. Many modern slow cookers have auto-shutoff or switch to a Warm setting when done.
