Slow Cooker to Pressure Cooker Time Converter
Turn any slow cooker recipe into electric pressure cooker (Instant Pot) minutes — or convert a pressure cooker time back to slow cooker Low and High.
Full Conversion Chart
| Slow Cooker – Low | Slow Cooker – High | Pressure Cooker (High) |
|---|---|---|
| 2 hours | 1 hour | ~6 minutes |
| 3 hours | 1½ hours | ~9 minutes |
| 4 hours | 2 hours | ~12 minutes |
| 5 hours | 2½ hours | ~15 minutes |
| 6 hours | 3 hours | ~18 minutes |
| 7 hours | 3½ hours | ~21 minutes |
| 8 hours | 4 hours | ~24 minutes |
| 10 hours | 5 hours | ~30 minutes |

Based on the widely used rule that slow cooker hours on High × 6 ≈ pressure cooking minutes, with 1 hour on High treated as roughly 2 hours on Low — the same Low/High ratio used in our Slow Cooker Time Converter.
Pressure Cooking Times by Food
The formula above works well for whole recipes, but for a single ingredient it's usually more accurate to start from a known per-food time. These are typical high-pressure times for an electric pressure cooker.
| Food | Pressure Time (High) | Slow Cooker Equivalent (Low) |
|---|---|---|
| Whole chicken | ~6 min per lb | 6-7 hours |
| Chicken breast (boneless) | 8-10 min | 3-4 hours |
| Chicken thighs (bone-in) | 12-15 min | 4-6 hours |
| Beef roast / chuck | ~15 min per lb | 8-10 hours |
| Pork shoulder (cubed) | 35-45 min | 8-10 hours |
| Beef stew meat | 20-25 min | 7-8 hours |
| Dried beans (unsoaked) | 25-40 min | 6-8 hours |
| Dried beans (soaked) | 8-12 min | 3-4 hours |
| Potatoes (cubed) | 4-8 min | 3-4 hours |
| Soups & broths | 15-30 min | 6-8 hours |
Times are for food at refrigerator temperature in an electric pressure cooker. Frozen ingredients take longer to come to pressure and may need extra cooking time. For meat, always confirm with the safe internal temperature rather than the clock.

How to Use This Converter
Pick a direction — Slow Cooker → Pressure if you're adapting a crockpot recipe for an Instant Pot or other electric pressure cooker, or Pressure → Slow Cooker if you have a pressure cooker recipe you'd rather leave to cook all day. Enter the time you already know and the converter estimates the equivalent. Because slow cooker recipes are usually written for Low, the converter accepts either setting and handles the Low-to-High step for you.
Why Pressure Cooking Is So Much Faster
A sealed pressure cooker traps steam, which raises the internal pressure and, with it, the boiling point of water. Instead of topping out at 212°F the way an open pot does, the environment inside reaches roughly 250°F at high pressure. That higher temperature drives the same connective-tissue breakdown that makes slow cooking work, but it does the job in a fraction of the time — which is why an 8-hour braise compresses into well under half an hour of actual cooking.
This is the mirror image of what a slow cooker does. A slow cooker's Low setting runs around 190-200°F and High around 290-300°F, both relying on long exposure at gentle heat. A pressure cooker gets to a higher temperature than either and simply spends far less time there. Both end up in the same place for tough cuts; they just take opposite routes.
The Time the Converter Doesn't Show You
The single most common surprise when switching from a slow cooker is that pressure cooking minutes are not the same as clock minutes. The cooking time only begins once the pot has actually reached pressure, and getting there takes 5 to 20 minutes depending on how full the pot is, how cold the contents are, and how much liquid is inside. Releasing the pressure adds more: a quick release vents in a couple of minutes, while a natural release can take 10 to 20 minutes as the pot cools on its own.
In practice, budget roughly 20 to 40 minutes of extra clock time on top of whatever cooking time this converter gives you. A recipe that converts to "25 minutes" realistically occupies closer to an hour from start to serving. That's still dramatically faster than eight hours in a slow cooker, but it matters if you're timing side dishes — and it's the reason a 6-minute pressure time doesn't actually mean dinner in 6 minutes.
Which release you use isn't only about time, either. Natural release lets the food continue cooking gently as pressure drops, which suits large cuts of meat and anything you want to stay tender. Quick release stops the cooking abruptly, which is what you want for vegetables, seafood, and pasta that would otherwise overshoot. If a recipe specifies one, the timing assumes it.
What to Change Besides the Time
Liquid usually goes up, not down. This trips up people who have learned to cut liquid for the slow cooker. A slow cooker traps moisture and needs less added liquid than an oven recipe; a pressure cooker also traps moisture, but it needs a minimum volume of thin liquid to generate steam in the first place — commonly about 1 cup for a 6-quart pot and 2 cups for an 8-quart, though your manual is the authority. A slow cooker recipe that relies on a roast's own juices may not clear that minimum.
Thick sauces go in at the end. Tomato paste, cornstarch slurries, roux, and heavy dairy can scorch on the bottom or trigger a burn warning, and dairy can separate under pressure. Pressure cook with thin liquid, then stir the thickeners in afterwards using the sauté function.
Nothing reduces in a sealed pot. A slow cooker loses a little moisture over eight hours; a pressure cooker loses essentially none. If the original recipe expected the sauce to concentrate, it won't — plan to simmer it down uncovered after cooking.
Delicate ingredients go in late. Quick-cooking vegetables, fresh herbs, and seafood turn to mush at the times that tough cuts need. Cook the long-cooking components first, release pressure, then add the delicate ones for a short second cook or just to warm through.
Stovetop vs Electric, and Altitude
Almost every pressure cooking time you'll find online — including the ones on this page — assumes an electric pressure cooker such as an Instant Pot. Stovetop pressure cookers generally operate at a higher PSI, so they run hotter and finish sooner. A reasonable starting adjustment is to trim about 15% off the cooking time for longer cooks and check early; for short cooks of only a few minutes the difference is usually small enough to ignore.
Elevation works the other way. Because water boils at a lower temperature as altitude rises, the pot reaches a lower actual cooking temperature even at the same pressure setting. The common adjustment is to add roughly 5% to the cooking time for every 1,000 feet above 2,000 feet — so at 5,000 feet a 20-minute cook becomes about 23 minutes, and at 8,000 feet closer to 26. Our High Altitude Cooking Calculator works this out for your elevation, alongside the boiling-point and moist-heat adjustments. This is the same underlying physics that makes candy and sugar work stages shift at elevation, covered in our Candy & Sugar Stage Temperature Calculator.
Frequently Asked Questions
How do I convert slow cooker time to Instant Pot time?
Convert the slow cooker time to its High-setting equivalent first, then multiply those hours by about 6 to get pressure cooking minutes. Since 1 hour on High is roughly 2 to 2.5 hours on Low, an 8-hour Low recipe is about 4 hours on High, which works out to roughly 24 minutes at high pressure. Treat the result as a starting point and confirm doneness with a thermometer for meat.
Does the converted time include the time it takes to come to pressure?
No. Pressure cooking time only starts counting once the pot has reached pressure, and building pressure typically takes 5 to 20 minutes depending on how full the pot is and how cold the contents are. Natural release adds another 10 to 20 minutes on top. Budget roughly 20 to 40 minutes of extra clock time beyond the cooking minutes this converter gives you.
Do I need to change the liquid when converting a slow cooker recipe?
Usually yes, and often in the opposite direction from what people expect. A pressure cooker needs a minimum amount of thin liquid to generate steam — commonly about 1 cup for a 6-quart model and 2 cups for an 8-quart, though you should check your manual. Slow cooker recipes that rely on the meat's own juices may not have enough, so you may need to add liquid rather than reduce it.
Can every slow cooker recipe be pressure cooked?
No. Braises, stews, soups, beans, and tough cuts convert well because both methods use moist heat to break down connective tissue. Dairy-heavy sauces can separate under pressure, delicate vegetables turn to mush, and anything meant to thicken by evaporation won't reduce in a sealed pot. Add dairy, quick-cooking vegetables, and thickeners after pressure cooking finishes rather than at the start.
Is a stovetop pressure cooker the same as an Instant Pot?
Not quite. Stovetop pressure cookers typically run at a higher PSI than electric models, so they cook somewhat faster. If you're using a stovetop pressure cooker with a time written for an electric one, a common starting adjustment is to reduce the cooking time by roughly 15 percent on longer cooks, then check doneness early.
Do I need to adjust pressure cooking time for high altitude?
Yes. Water boils at a lower temperature as elevation rises, so the pot reaches a lower actual cooking temperature. A widely used rule is to add about 5 percent to the cooking time for every 1,000 feet above 2,000 feet of elevation. At 5,000 feet, that means a 20-minute cook becomes roughly 23 minutes.
