Slow Cooker / Instant Pot Time

Converting Cook Time Between Slow Cooker, Instant Pot, and Stovetop

Different cooking methods take dramatically different amounts of time for the same dish, due to their heat intensity and airflow. This calculator applies commonly-published multipliers relative to a Stovetop/Oven baseline.

The Formula

$$\vB{\text{Converted Time}} = \frac{\vA{\text{Original Time}}}{\text{From Multiplier}} \times \text{To Multiplier}$$

Multipliers relative to Stovetop/Oven (1×): Slow Cooker Low ≈ 4×, Slow Cooker High ≈ 2×, Instant Pot ≈ 1/3×.

These are general rule-of-thumb ratios, not exact conversions — always check for doneness.

Worked Example

30 minutes on the stovetop, converted to Slow Cooker Low:

1. $\vA{30} \times 4 = \vB{120}$ minutes (2 hours)

Key Factors to Consider

• A recipe’s ingredients and cut size affect how well these general multipliers hold up. Dense root vegetables and larger cuts of meat generally need more time regardless of method, while delicate ingredients like dairy or seafood can overcook quickly in a slow cooker even at the “correct” converted time — these ratios are a solid starting estimate, not a replacement for checking doneness directly.
• A slow cooker’s “Low” and “High” settings differ mainly in cooking speed, not final temperature reached. Both settings eventually bring food to a similar safe internal temperature — High simply gets there faster, which is exactly why the two settings use different time multipliers relative to the same stovetop baseline.
• Pressure cookers (like an Instant Pot) cook faster specifically because pressurized steam raises the boiling point of water above 212°F/100°C. This is the physical reason pressure cooking is so much faster than slow cooking or stovetop simmering — it’s a fundamentally different heat-transfer mechanism, not just a “turned up” version of the same process.
• Always verify doneness with a food thermometer for meat and poultry, regardless of which converted time this calculator suggests. These ratios are useful planning estimates, but a thermometer reading the actual internal temperature is the only reliable way to confirm food safety, since actual cooking time can vary by specific appliance, altitude, and ingredient starting temperature.

Common Mistakes

• Treating the converted time as an exact stopping point rather than a starting estimate. These multipliers are general rules of thumb — the actual time still depends on the specific recipe, appliance, and ingredients, so always check for doneness rather than pulling food the instant the timer hits the converted figure.
• Converting in the wrong direction. It’s easy to accidentally multiply instead of divide (or vice versa) when converting between a slow multiplier like Slow Cooker Low and a fast one like Instant Pot — double-check that the converted time actually makes sense (longer for slower methods, shorter for faster ones) before cooking.
• Assuming every ingredient converts at the same rate. As the Key Factors above note, delicate ingredients like dairy or seafood can overcook well before a converted slow-cooker time is up, even when the multiplier itself is correct for the dish overall.
