While slow cookers and pressure cookers can often be used to cook the same sorts of foods—like tough meats—the way they go about that cooking is completely different. Slow cookers are designed to cook food gently and for a long time. Pressure cookers are designed to cook food at a temperature that’s higher than the normal boiling point (because of the pressure), and they cook much faster.
If you only have room, or budget, for one of these devices, which should you choose?
Slow cookers tend to be... less expensive, particularly on the low end of the price range, since they don’t need a lot of technology for their most basic tasks. The least expensive slow cookers might just have high, low, and off settings, with no timer or extra features. Higher end machines might have timers, a keep-warm function, or a browning function. The slow cooker is ideal when you want to cook your food unattended, or even when you’re not at home. Many people put food in a slow cooker before going to work so it’s ready when they come home or they leave food cooking overnight. Since the slow cooker doesn’t need to stay sealed during cooking, you can taste for seasoning or add ingredients throughout the cooking process.
Electric pressure cookers tend to be more expensive than slow cookers, since there’s a bit more technology and engineering involved. For safety, the lid locks on during pressure cooking and it won’t unlock until pressure has been released. Because of that, it’s best to cook recipes that don’t require tasting during the process and that don’t need ingredients to be added at different times. Since the pressure cooker speeds up the normal cooking times, you can put foods in the cooker after work and have dinner on the table quickly. But since the time is generally so short, you probably wouldn’t leave it cooking while you’re at work. Electric pressure cookers generally have extra functions that make them more versatile, like a browning function as well as the ability to slow cook.
If a pressure cooker can also slow cook, why wouldn’t someone choose it over a slow cooker? For one thing, many slow cookers are oval-shaped to accommodate large roasts or whole chickens, which might not fit well in a pressure cooker. For another, while pressure cookers are safer than they were in the past, many people have a lingering fear of them. And last, pressure cooking is a completely different technique than cooking on the stove, so there is a bit of a learning curve, whereas using a slow cooker is very similar to cooking on the stove, so it’s much more familiar.
Once you’ve decided which appliance is right for you, here are the best options on the market.
Not only does this slow cooker have the basic functions, it also has a few special features that you won’t find in other slow cookers, like the temperature probe than can be used to check the temperature of a roast while it cooks. This is a programmable slow cooker with a keep-warm setting, but you can also opt to ignore the programming and use it manually.
The oval shape of this 6-quart cooker means there’s plenty of room for a roast or large chicken. It’s designed for travel, with clips that... hold the lid on, and a gasket for a tight seal. Sturdy handles make it easy to carry. It also includes a spoon that clips to the cooker, so it’s handy for serving.
There are three settings: program (which allows you to set a cooking time) probe (which uses the temperature probe to determine doneness) and manual (which lets you set high, low, or warm temperatures without setting a cooking time).
