If you are new to pressure cooking there are probably a few basic questions you have right off the bat regarding the liquids added to the pot.
- How much liquid goes in a pressure cooker?
- Do you always have to add water to a pressure cooker?
These might sound like pretty simple questions, but unless you’ve used a pressure cooker before it’s it’s not uncommon to wonder to yourself!
Cooking with liquid is the most fundamental aspect of making food inside electric and stovetop pressure cookers. For the majority of cases, this’ll be water, but you may be using pre-prepared broth, stock, or other cooking liquids depending on what you’re making.
But Does a Pressure Cooker Need Water Every Time?
Yes, a pressure cooker needs water, or some kind of liquid like broth, every time you use it.
Why does Pressure Cooking Need Water – What is it For?
Water essentially serves the same basic purpose as it does in traditional cooking methods: heating the water is what causes the food to cook. However, it’s a bit more complicated than that when you consider pressure and altitude, and it’s this complication that makes pressure cooking a far more effective way of preparing food.
Pressure cookers work by sealing in steam, which raises the liquid above the boiling point and creates pressure. If there is no liquid, there is no steam. If there is no steam, there is no pressure cooking. Most recipes will call for at least one cup of liquid, unless a specific recipe calls for less, always use that amount at the very least.

As an added note, you should never fill your pressure cooker with liquid beyond the halfway mark, and never more than two-thirds full of food. Pressure cannot build if there is no room for the steam to create it.

How Much Water Does a Pressure Cooker Need to Work?
Most recipes which factor in pressure cooking should provide you with instructions, and this may also vary depending on the size of the pressure cooker you are using. For instance you would always use less water in a 2-quart pressure cooker than you would in a 10-quart model.
A good rule-of-thumb, however, is never to fill it more than half-way. That’s more than enough for almost every possible use!
Can I Only Boil Food in a Pressure Cooker?
No, there are several methods you can utilize when pressure cooking. Boiling is the best method for dishes like soups and stews, but you can also braise, which uses minimal liquid. Steaming your food, by lifting foods above the liquid with a steamer basket, is another common way of pressure cooking certain foods. A very common example of a food that is cooked with pressure steaming would be veggies or eggs.
You can also brown and deglaze food in your pressure cooker to maximize flavor before you begin pressure cooking. Just leave the lid off and add a small amount of oil to brown food like some vegetables like carrots, celery, peppers and onions, poultry and meat to your pot, and use a medium heat setting. Then, once your food is browned, remove it and set it aside. With the heat still on, add a liquid like broth or wine to deglaze the pan, making sure to lift off any stuck food particles from the bottom of the pan.
Take the food you previously set aside, add it back to your pressure cook, add your remaining ingredients and follow your pressure cooking manual’s recommended cooking times to finish your dish. This method is for a stove-top pressure cooker, you can follow a similar process in an electric pressure cooker if it has a ‘brown’ setting option.
Does Pressure Cooking Really Save That Much Time?
Yes, pressure cooking can cook food up to 70% faster than conventional cooking. However, not all pressure cookers are the same.
If you have a standard pressure cooker, it can reach the maximum pressure of 15 psi (pounds per square inch). If you have a non-standard pressure cooker, check the manual to see what the maximum psi is for your model. Most recipes designed for pressure cookers will assume you are using a standard pressure cooker.
When getting use to pressure cooking, always err on the side of your food being underdone, which is an easy fix, simply return the pan back to the stove, reseal the lid and let it return to high pressure for a few more minutes.
Can I Open the Lid While Cooking to Peek at My Food?
Never attempt to open or take the lid off your pressure cooker while it is under pressure. Most modern models make this virtually impossible to do, but for your own safety, never attempt it. You should always release the pressure first before removing the lid. Most recipes will tell you what the appropriate method is for that particular dish. It is advantageous to get familiar with the various release methods.
Pressure cooking is simple once you get the hang of it and will save you a great deal of time and energy.
