Pressure Cooker vs Slow Cooker – Which One is Best for You?

A cooker is an essential appliance in every kitchen. You need to rely on cookers, from comfy overnight slow-cooked stew to cooking beans quickly. 

But which type of cooker is best? Is a pressure cooker better than a slow cooker? Apparently, both look the same, but the working principle is totally different from each other. 

Being a professional chef, I’ve used both for a long time. The one thing I can assure you is that both are not interchangeable. 

So, if you’re confused about which cooker type suits you the most, read on for your detailed information. I have compared both in energy consumption, taste, and nutrition factor.

Slow vs Pressure Cooker – What’s The BIG Difference?

If you search the difference between both cooker types, you’ll probably end with the answer, “slow cooker cooks food slowly while an electric pressure cooker cooks fast” Isn’t that obvious? 

There are several factors that determine the “best type.” So, here’s your detailed comparison.

  3. Both types ensure trap nutritional values, but the electric pressure cooker is clearly a winner, as it provides less time for essential vitamins to disintegrate or dissolve.

Won’t Pressure Cooking Destroy Minerals In Food?

No, it’s just a myth. Food minerals are carbohydrates, vitamins, protein, fiber, and fats. All these minerals can withstand 110°C (230°F) to 125°C(257°F). According to research by The Journal of Food Science, pressure cooking preserves 90% to 95% of vitamins.

Slow Cooker vs Pressure Cooker – What About Maximum Temperature?

The pressure cooker built an insane pressure of up to 30psi. At 15psi, the temperature reaches up to 120°C(248°F). 

Almost all instant cookers can achieve 15psi. The maximum withstanding temperature is 240°C(464°F).

On the contrary, slow cookers cook your food for several hours at 76°C(170°F). After five to six hours, it reaches up to  137°C(280°F). 

If you open the lid at any time, the temperature decreases drastically.

Pressure Cooker vs Slow Cooker – Which Last Longer?

A pressure can last up to three to four years, while a slow cooker is suitable for five to seven years.
It generally depends on how rugged you use them, built quality, average use, and surrounding conditions.

Compared to traditional electric ceramic cookers, a pressure cooker last 2 years more.
