    Tips

    Reduce liquid by about one-third since slow cookers retain more moisture. Do not lift the lid during cooking; each peek adds 15-20 minutes.

    Worked Example

    Convert a 60-minute oven recipe at 350°F to slow cooker.

    oven_time_min = 60oven_temp_f = 350
    1. 01Slow cooker LOW: 60 x 4 = 240 minutes = 4 hours.
    2. 02Slow cooker HIGH: 60 x 2 = 120 minutes = 2 hours.
    3. 03Reduce liquid in the recipe by about 1/3.

    Frequently Asked Questions

    What temperature is slow cooker LOW and HIGH?

    LOW is approximately 190°F (88°C) and HIGH is approximately 300°F (149°C). Both reach the same final temperature, but LOW takes longer.

    Can I convert any recipe?

    Most braises, stews, soups, and casseroles convert well. Recipes that rely on dry heat, browning, or crispiness do not work well in a slow cooker.

    Should I reduce the liquid?

    Yes, reduce by about one-third. Slow cookers trap steam, so less evaporation occurs compared to oven cooking.
