How do I convert slow cooker recipes to a pressure cooker with different cooking times?

There is no single conversion factor that turns a slow cooker time into a pressure cooker time, because the two methods work differently: a slow cooker cooks at a low, steady temperature for hours, while a pressure cooker raises the internal temperature with steam pressure and finishes in a fraction of the time. The practical approach is to keep the recipe’s ingredients and seasoning, cut the liquid, and start with a much shorter pressure time than the slow cooker time, then check doneness and add minutes if needed.

The makers themselves describe the gap only in general terms. Instant Pot states that its Duo 6 Qt cooks “up to 70% faster compared to slow cooking methods,” and Midea makes the same “up to 70% faster” claim for its 12-in-1. Neither publishes a recipe-by-recipe conversion chart, so those figures describe the category, not a formula you can apply to a specific stew.

Why the two methods need different times

A slow cooker holds food at a gentle temperature for a long stretch, so a pot roast that takes 8 hours on low is really being cooked slowly and evenly rather than quickly. A pressure cooker seals in steam, which raises the boiling point and drives heat into the food faster. That is why the same dish can be done in well under an hour. The Best Pressure Cookers for Canning and Fast Meals guide lists several models whose makers frame the speed advantage in exactly these terms.

The Instant Pot Duo 6 Qt, for example, is a 6-quart electric model with 7 cooking functions including pressure cook and slow cook, and its maker states it cooks up to 70% faster than slow cooking methods. The Midea 12-in-1 is an 8-quart electric cooker with 12 functions and the same up to 70% faster claim. Read those as a general sense of the time saved, not as a number to subtract from your recipe.

Cut the liquid, because pressure cooking adds none back

Slow cooker recipes often call for a lot of liquid because little evaporates over hours with the lid on. A pressure cooker traps steam completely, so the liquid you add stays in the pot and the dish can come out thin. Start with roughly half to two thirds of the liquid the slow cooker recipe lists, and keep enough to bring the pot up to pressure and prevent scorching. Thicken at the end with a slurry or a reduction rather than at the start.

Dairy, wine and thick sauces behave differently under pressure and are usually added after the pot has been vented. If your slow cooker recipe finishes with cream or cheese stirred in, hold that step until the pressure has released. The same goes for delicate herbs and anything you want to keep bright.

Match the recipe to the pot you own

Capacity matters more than most conversion advice admits. The Instant Pot Duo 6 Qt is a 6-quart model sized by its maker for up to 6 servings, and the Cosori Pressure Cooker 6QT is also a 6-quart unit. A slow cooker recipe written for a 7-quart Crock-Pot, which its maker says serves 9+ people or fits a 7-pound roast, will not fit a 6-quart pressure cooker without cutting it down. Scale the recipe to the pot rather than filling past the maximum line.

On the slow cooker side, the Best Slow Cookers for Batch Cooking and Entertaining guide includes the Ninja PossibleCooker PLUS at 8.5 quarts and the All-Clad 7-quart model. If your original recipe was built for one of those larger pots, halve or third it before converting, and remember that a pressure cooker should not be filled to the brim.

Set a starting time, then check

Because no maker publishes a conversion table, treat your first attempt as a test. A common working method is to take the slow cooker’s low-setting time and start the pressure cooker at a small fraction of it, then release pressure and check the food. If it is underdone, lock the lid and add a few minutes. If it is done, you have your new time for that dish. Write it down, because the next batch will be the same.

Dense foods like beans, tough cuts and root vegetables need the most adjustment, while soups and sauces come together quickly. The Instant Pot Duo 6 Qt lists 13 one-touch programs, and the Midea 12-in-1 lists modes for soup, bean chili, rice and oatmeal, which give you a sensible starting point before you fine-tune. Use the preset as a baseline, not as a guarantee.

Brown and saute first, then pressure cook

Many slow cooker recipes skip browning because the long cook softens everything anyway. Under pressure, browning first builds flavor that the shorter cook will not develop on its own. Several of the pressure cookers in our guide offer a saute function for this: the Instant Pot Duo 6 Qt lists saute among its 7 functions, the Midea 12-in-1 lists saute, and the Cosori 6QT lists Saute as one of its modes. Brown meat and soften aromatics in the pot, then add liquid, seal and cook.

After the pressure cook, let the pot vent as the maker instructs. The Instant Pot Duo 6 Qt uses an Easy-Release steam switch, and the Cosori 6QT places its Seal/Vent button away from the steam release valve with a backward-angled vent. Follow those directions rather than guessing, especially with starchy or creamy dishes that can sputter.

What the makers do and do not publish

The makers publish capacity, functions and general speed claims, but not a slow cooker to pressure cooker conversion chart. Instant Pot and Midea both state up to 70% faster cooking than slow cooking methods, and that is the extent of the timing guidance on the fact sheets we hold. The slow cooker makers publish settings and capacities, such as the Crock-Pot 7-quart fitting a 7-pound roast, but nothing that maps their times onto a pressure cooker.

So the honest answer is that you build the conversion yourself: less liquid, a shorter starting time, a check for doneness, and a note of what worked. Our guides compare the published figures for each pick, and where a maker does not publish a number, we say so rather than invent one.
