Slow Cooker Conversion Calculator

Convert recipe cook time between oven, stovetop, slow cooker (low or high), and pressure cooker. Adjusts for food type and adds liquid, seasoning, and food-safety guidance.

Convert cooking time

New cooking time

6 h 36 min

396 minutes (6.6 hours) using a factor of 6.6x.

Temperature

Use the LOW setting (about 200 F / 93 C inside the crock).

Liquid adjustment

Slow cookers trap nearly all moisture, so cut the original liquid by about one third. Add it back at the end only if the sauce is too thick.

Seasoning timing

Stir in delicate herbs (basil, parsley, cilantro) and ground spices in the last hour so their flavor and color survive. Dried hardy herbs (bay, thyme, rosemary) can go in from the start.

Food safety

Always confirm meat reaches a safe internal temperature with a probe thermometer. Poultry must hit 165 F (74 C); whole-muscle beef, pork, and lamb need at least 145 F (63 C); ground meat needs 160 F (71 C). With the slow cooker on low, check the thickest piece, not the broth.

Frequently Asked Questions about the Slow Cooker Conversion Calculator

How do I convert an oven recipe at 325 F to slow cooker low?
Multiply the oven time by about 6. A pot roast that takes 1 hour at 325 F in the oven runs roughly 6 hours on low in a slow cooker; a 2 hour braise becomes about 12 hours, which is at the edge of an all-day cook. The 6x ratio works because a slow cooker on low holds the food at around 200 F, well below the 325 F oven, so the collagen-melting chemistry that tenderizes tough cuts simply needs more time. Cut the original liquid by about one third before you start, because almost no moisture escapes a sealed crock.
What is the difference between slow cooker low and high?
Low and high generally reach a similar simmering range, but high gets there sooner. Food in a water-based slow-cooker dish cannot remain at 300 F under normal atmospheric pressure. Conversion ratios vary by appliance and recipe, so follow a tested slow-cooker recipe when food safety or texture is critical.
How do I convert a conventional recipe to a pressure cooker?
Divide the conventional cook time by about 4. A 60 minute oven or stovetop braise becomes roughly 15 minutes at high pressure once the pot reaches pressure. Add about 10 minutes of build-up time and 10 to 15 minutes of natural release for meat, and the total clock time is still well under the conventional version. Always include at least 1 cup (240 ml) of thin liquid so the pot can build steam, and skip flour or cornstarch thickeners until after pressure is released, because they can scorch on the bottom and trigger a burn warning.
How do I know meat is safe in a slow cooker?
Start with thawed ingredients, follow a tested recipe, and check the thickest part with a food thermometer. If the cooker failed, lost power, or food may have stayed in the danger zone for an unknown period, do not assume that finishing it later makes it safe. Follow current USDA guidance and discard food when its time-temperature history is uncertain.
Why do slow cookers need less liquid than stovetop or oven recipes?
A slow cooker traps almost all moisture under its lid. Whatever liquid the food releases stays in the pot instead of evaporating, so a stew or braise will end up watery if you use the full liquid amount from an oven recipe. The rule of thumb is to cut the liquid by about one third when adapting an oven or stovetop recipe for the slow cooker. If the sauce is too thin at the end, lift the lid for the last 30 to 60 minutes on high, or stir in a slurry of cornstarch and water and let it thicken uncovered.
