I once stood in front of my Instant Pot, holding a steamer basket one hand and a handful of eggs in the other and thought to myself:
"Am I steaming these eggs or pressure cooking them? ...or am I pressure steaming them?"
This is probably a common question that many beginners have and it's probably why you are reading this page now.
To answer your question in the shortest way possible I'd say that there is a difference between presser cooking and steaming. Steaming is when you just cook your food with steam.
You can steam your food in a pressure cooker and you can pressure steam your food in the same pot so long as it's sealed up tight enough.
Let's try to understand this a bit better though, stick with me.
How Pressure Steaming is Just Like Pressure Cooking
While both pressure cooking and steaming (natural or using a steamer basket) are reliable, popular alternatives to the more traditional method of cooking on a stovetop cook top or induction hob, the differences between them are well worth knowing if you want to get the most out of your experience in the kitchen!
As you may know, you can do the Instant Pot water test by setting 5 minutes of high pressure or 2 minutes of steaming. So are they really that similar?
In this article, we’ll cover some of the key distinctions between these two methods, as well as providing you with some helpful links to inspire you with recipes and ideas to bring into your kitchen.
How to Cook Perfect Vegetables With Steam
When it comes to cooking vegetables, most of the science today suggests that the old methods of simply bringing a pan to boil, chuck them in, and draining after a few minutes is incredibly wasteful. As this Healthy Eating blog explains, the longer your vegetables are submerged in water, the more the important vitamins and minerals which they contain are allowed to seep out into it. Given that you eventually discard the water, this is incredibly inefficient!

A Pressure Can Can Both Steam Food & Pressure Steam Your Food
One significant advantage which a pressure cooker has over a steamer is that it can be used in far more situations and with a much wider range of ingredients. This means that one appliance can take on the role previously occupied by several more specialized pieces of equipment!
Steamers, in the majority of cases, are primarily designed to help you with cooking vegetables. As mentioned above, they are extremely effective in doing so, and provide many health benefits over simply boiling on a cooktop. However, pressure cookers also provide all these benefits and more in the form of their superior versatility.
Soups, rice, various meats, and pulses: all of these and more can be cooked in a pressure cooker, whereas most consumer steamers aren’t made to handle this sort of variety.
Pressure Cooking with Steam Also Saves a Lot of Time
Perhaps the most interesting distinction between a pressure cooker and a dedicated steamer, however, is how much faster and more effective pressure cooking is than steaming food. Pressure cookers are often around ten times more efficient and faster than many other methods of cooking!
The science is simple to understand: cooking at a higher pressure means that food can be cooked at a temperature which exceeds the normal boiling point of water. The trapped steam and much lower quantity of water makes this possible, and the results are astounding.
Pressure Cooking vs Steaming: Which is Best?
There isn’t really a 'best' option, because it all depends on what you’re planning to do. However, for its versatility, massively increased speed, and the ease with which you can create entire dishes, the pressure cooker comes out in front in my book. Providing all the benefits of a steamer and then some, it’s the optimal choice for any home kitchen.
