Pressure Cooker vs Slow Cooker: The Pros and Cons

Few meals stick to the ribs and provide almost instant comfort the way that slow-cooked meals do when the weather starts to get chilly.

Differences between slow cookers and pressure cookers. A slow cooker is a gentle process that uses low heat and low temperature, longer cooking times to help keep your dish from being overcooked or dried out. A pressure cooker can bring the same results in less than half the time by using high temperatures, hot steam with high pressure.

The only problem with a slow cooker, though, is that it takes a long time to turn often tough and otherwise inedible ingredients into the kind of food you’d find in a four-star restaurant.

You have to get up early, you have to prep your meal in advance, and then you have to hope that nothing goes sideways during the day to cause your slow cookers cooking time to “go on the fritz”.

Of course, you could speed things up with pressure cooking – but that introduces a couple of curveballs into the mix, too.

People have been arguing both sides of the great pressure cooker vs slow cooker debate for decades now, and the odds are pretty good they’re going to keep right on arguing this debate for at least another generation (or two).

This detailed breakdown of the pros and cons of both of these miracle kitchen appliances is my small contribution to the fight.

Hopefully, by the time I wrap up we shine a light on what these appliances do well, where they fall short, and maybe nudge you in the right direction towards what we think is the better choice. Let’s get right into it…

Pressure Cookers

Pressure cookers, up until just recently, were almost exclusively thought of as equipment used for canning and storing food for the long haul or to cook things like rice quickly and evenly.

Stovetop pressure cookers used to be a real nightmare to try and control, super difficult to dial in, and generally pretty unsafe.

It wasn’t at all uncommon for these kinds of appliances to “blow their top” without any warning at all – not only tossing superheated steam all over the place in the process but usually expelling whatever was inside the pressure cooker all over your kitchen, too!

Today’s pressure cookers, though, are a whole lot more advanced than they ever used to be.

In fact, many of the best pressure cooker options on the market today don’t ever see the top of a stove.

Instead, they are 100% electric, with automatic shut-offs built right in, and some even have advanced computer capabilities on board (including wireless internet) to make them about as safe and as easy to use as humanly possible.

Not only that, but many of today’s best pressure cooker options are so much more than just a pressure cooker.

Most of them are now being called “multi cooker” – the pressure cooker that handles double duty (and then some) as a pressure cooker, yogurt maker, a rice cooker, a tool for canning, a quick way to make two, and chili, a great way to make rice, and that’s just the tip of the iceberg. Slow cooker recipes like a pot roast are at home in today’s electric version of pressure cookers.

The safety features, the new locking mechanisms, and the automatic relief valves are a handful of things that today’s modern pressure cooker has going for them, too.

That’s not to suggest that today’s pressure cookers are perfect, though.

This type of cooker can be a nightmare to clean, you still have to babysit them (at least a little bit) to make sure that things don’t go sideways, and the high rate of speed during the pressurized cook usually cuts out a little bit of the deeper and more nuanced flavors you get from a slow cooker.

Pressure Cooker – Pros and Cons

Here’s a quick rundown of the pros and cons of today’s pressure cooker to give you a better idea of what they are bringing to the table:

Pressure Cooker – PROS

• You can often cook a “slow cooker only” meal that might have taken eight hours or longer in about 90 minutes flat using higher temperatures
• You don’t have to worry about a pressure cooker heating up your entire kitchen the way that a slow cooker might
• By cooking with steam you’re able to retain a lot of the vitamins and minerals with a pressure cooker that would have been lost with other cooking methods
• Most of today’s modern pressure cookers are “multi-cooker” units that do so much more than just speed up the cooking process
• Many of today’s best pressure cookers even include Wi-Fi capabilities so that you can control your cooker from anywhere – including the office or at school – while online
• Electric pressure cookers are even more integrated offering air fryer capabilities
• Combine the temperature setting capabilities the fast cooking time, airtight seal from the locking lid you are going to save a lot of time

Pressure Cooker – Cons

• On the flipside, pressure cookers are always a nightmare to clean. You have to pull everything apart, clean everything carefully, and then put everything back together – every single time you cook with one
• You might not need to carefully watch every second of today’s modern pressure cooker, but they still have some rest of them and shouldn’t be left completely unattended
• You need to be real careful when popping the top on modern pressure cookers, as the steam can scald and burn you
• You do lose a little bit of those nuanced and subtle flavors when you cook this quickly under pressure
• The price tag on quality pressure cookers (especially those with multi cook functions) is almost always a lot higher than a slow cooker
• You have to convert slow cooker cook times to account for the much more rapid cook time of a pressure cooker, and you often have to do that all on your own

Slow Cookers

The very first slow cooker (the actual slow cooker that would later become the legendary “Crock Pot”) was invented all the way back in 1940.

To put it bluntly, slow cookers have been around for a while – a long while!

And while some would say that this makes the slow cooker a little outdated and not quite as useful in today’s lighting fast-paced world, others would say that all this time has only made the slow cooker better. (Kind of how the slow cooker itself works.)

Over decades the slow cooker technology has been refined, improved upon, and – quite literally – perfected.

Today’s slow cooking technology is very similar to the slow cooker of the past, but a lot more efficient, a lot more effective, and (believe it or not) a little bit faster!

Not too fast, though, as the slow and deliberate cooking process that these appliances use – perfecting low and slow – are responsible for transforming otherwise rather “blah” ingredients into something really spectacular.

Sure, you need to devote a decent chunk of time to preplanning how you’re going to use your slow cooker if you want to use it effectively.

And sure, you’re probably going to need to throw dinner together into this countertop appliance before you leave for school or work if you want to have it ready when you get home.

But these bulky, often cheap little units are truth tanks in the kitchen. They are legitimately set it and forget it solutions that make cooking downright effortless.

If you can rough chop ingredients (and sometimes you don’t even have to go that far), dump everything into your slow cooker, and then flip the switch to LOW – and then leave everything for hours and hours – you’re going to be able to make some amazing dishes with this simple set up.

Slow Cooker Pros and Cons

• Slow cookers require you to be really organized if you’re going to use them effectively
• Slow cookers are always a little bit bigger and a little bit bulkier than most of your other cookware and small appliance options, which can be a pain to keep on the counter or to find storage space for

Pressure Cooker vs Slow Cooker – Final Verdict

At the end of the day, you really can’t go wrong with either of these two amazing kitchen appliances.

You have learned that we no longer need the conventional cooking methods of a Dutch oven. Using these pots we were cooking over high heat for a long period of time to get our tough cuts of meat in our favorite hearty stew soft enough to chew.

A pressure cooker for home use is designed to get the job done in a hurry, but if you’re not in a rush or if you can set things up in the morning to eat at night a slow cooker develops even tastier flavors.

Of course, a pressure cooker (especially today’s pressure cooker) is generally a lot safer to use than a slow cooker – and almost always has a lot more functionality built right in.

When you get right down to it, the best small appliance to buy is a pressure cooker that doubles as a “multi-cooker”. Then you get the best of all worlds, having the opportunity to cook in slow cooker mode, pressure cooker mode, and a handful of other ways, too.
