Pressure Cooker Buying Guide: PSI, Capacity, and Valve Types Explained

Modern pressure cookers have 2 to 3 redundant safety systems: a primary pressure relief valve, a secondary pressure relief valve, and a lid-locking mechanism that prevents the lid from being opened under pressure. The lid cannot be opened while the cooker is pressurized on any modern design. Explosions associated with pressure cookers in news coverage almost exclusively involve pre-1970 models without modern safety systems, or extreme misuse (blocking all pressure relief valves). Following the operating instructions (do not fill past two-thirds, always use the pressure release valve before opening) makes modern pressure cookers safe household appliances.

Stovetop pressure cookers are compatible with gas, electric coil, electric glass-ceramic (smooth top), and induction stovetops. The only requirement: stainless steel for induction compatibility (aluminum is not induction-compatible). Verify the base is flat and stable on glass-ceramic surfaces, a warped or rough base can scratch smooth glass stovetops. All modern stainless steel pressure cookers from reputable brands are induction compatible. Check the packaging for the induction symbol if this is a concern.

Natural pressure release (NPR): remove the pressure cooker from heat and let pressure drop on its own. Takes 15 to 30 minutes depending on contents volume and temperature. Best for beans (prevents blowout from foamy liquid), thick soups, rice, and foods where continuing to cook while pressure drops is acceptable. Quick release (QR): manually move the venting valve from sealing to venting. Pressure releases in 1 to 3 minutes. Best for vegetables, fish, and foods that would overcook during a long NPR. Electric pressure cookers do quick release by moving the vent knob while still on the counter, keep your hand away from the steam vent.
