What does the Instant Pot Pro's custom pressure setting actually do?

The Pro allows setting pressure in 1-PSI increments from a low of approximately 5 PSI to a high of 15 PSI. Standard Instant Pot models (Duo, DUO60) have two settings: Low (5 to 7 PSI) and High (10 to 15 PSI). The Pro's custom setting lets you dial in a specific pressure for recipes that specify an intermediate level — for example, certain canning references specify 10 PSI for lower-acid vegetables, which is achievable on the Pro but only approximated on the Duo. In practice: most households cook 90%+ of their Instant Pot recipes at High pressure (15 PSI) and Low pressure (approximately 5 to 7 PSI). The custom PSI setting is a meaningful precision feature for enthusiasts who follow technically precise recipes or use the Pro for canning; it is a nice-to-have for households that primarily cook standard recipes.

How does the Instant Pot Pro's sous vide function work?

The Pro's sous vide function maintains the insert at a precisely set temperature between 104 and 208 degrees Fahrenheit in 1-degree increments. Food in a sealed bag is submerged in water in the insert, and the Pro holds the water at the set temperature for the set duration. The advantage over a dedicated sous vide circulator: no additional equipment (the Pro replaces both). The limitation: the Pro's insert is a stationary heated vessel without a circulation pump. True sous vide requires water circulation to maintain even temperature throughout the water bath. The Pro's static heating achieves temperature accuracy of approximately ±2 to 3 degrees in the water without circulation, compared to ±0.1 to 0.5 degrees in a dedicated circulator. For most sous vide applications (chicken breast at 140 degrees for 90 minutes, steak at 130 degrees for 2 hours): the ±2 to 3 degree variance is acceptable. For precision applications (65-degree eggs, custard): a dedicated circulator is more accurate.

Is the Instant Pot Pro worth $40 to $50 more than the Duo?

The Pro is worth the premium for three specific households: (1) frequent Instant Pot users who have outgrown the Duo's two-setting pressure control and want 1-PSI increments; (2) households with 5 or more distinct recipes they make weekly and want to store as saved programs; and (3) users who find touchscreen interfaces significantly more comfortable than dial interfaces. The Pro is not worth the premium for: households that use the Instant Pot primarily for soups, beans, and grains on High pressure (the Duo does this identically), first-time pressure cooker users who should establish their habits before investing in advanced features, and households for whom $50 is a meaningful price difference. The Pro's core pressure cooking performance is the same as the Duo — the premium pays for interface and feature refinement, not better pressure cooking.

How does the Pro's sterilize function work?

The Pro's Sterilize function heats water in the insert to boiling (212 degrees at normal atmospheric pressure) and maintains the boil for a set time. Items placed on the steaming rack above the boiling water are sterilized by steam contact at temperatures that kill most bacteria, mold, and yeast. Common sterilize applications: baby bottles and nipples (10 to 12 minutes), canning jars before filling (10 minutes), fermentation equipment (5 to 8 minutes). The sterilize function is not the same as pressure canning — the Pro does not maintain pressure during sterilize mode, so it cannot replace an FDA-approved pressure canner for canning low-acid vegetables, meats, and beans. For canning acidic foods (jams, pickles, tomatoes) that use a boiling water bath: the Pro's sterilize function is appropriate. For pressure canning: use a dedicated pressure canner.

Instant Pot Pro Review: The Best Instant Pot for Frequent Users

The Instant Pot Pro 10-in-1 6-Quart sits at the top of Instant Pot's consumer lineup, priced at $120 to $150 and built for households that pressure cook often enough to justify the touchscreen interface and 28,000 backing ratings at 4.7 stars. Where the base Duo offers only High and Low settings, the Pro allows pressure adjustment in 1-PSI increments from roughly 5 to 15 PSI, along with five saved cooking programs that recall a full function, time, and release configuration in one tap. It adds sterilize and sous vide modes on top of the seven functions carried over from the Duo, plus an inner cooking pot with handles that makes lifting a full insert noticeably easier. The tradeoffs are real: the touchscreen shows fingerprints more readily than a dial, and the $40 to $50 premium over the Duo only pays off for specific use cases. This review breaks down whether that premium is worth paying for your kitchen.

What the Instant Pot Pro Is

The Instant Pot Pro 10-in-1 is the current flagship model in the consumer Instant Pot line — the step above the Duo in interface and features, below the Max in pressure range. At $120 to $150, it targets the household that uses a pressure cooker regularly enough to benefit from the Pro's advanced controls and saved program slots.

28,000 ratings at 4.7 stars is well-validated for a premium appliance, though with significantly less community mass than the Duo's 145,000-rating base. The larger validation gap is partly because the Pro is newer and partly because Duo owners who are satisfied rarely upgrade.

Touchscreen Interface

The Pro replaces the Duo's dial selector with a color touchscreen panel. Functions are displayed as named buttons (Pressure Cook, Slow Cook, Sauté, Steam, etc.) with sub-options accessible through the same screen. The current status — function, time remaining, pressure level — appears in one view without mode-switching.

Daily use difference: the Duo's dial interface requires rotating to the function icon, pressing Pressure Level if needed, and pressing time. The Pro's touchscreen shows the full menu at once and allows tapping the desired function directly. For households that change between functions frequently or use multiple functions in one cooking session (sauté then pressure then keep warm): the Pro's interface is meaningfully more convenient. For households that do the same two or three functions every time: the Duo's interface is adequate.

Custom Pressure and Saved Programs

The ability to set pressure in 1-PSI increments gives the Pro a capability the Duo does not have: precise intermediate pressure levels. Most users will never need this. For the subset that follows technically specific pressure cooker recipes (certain canning guidelines, restaurant recipes that specify PSI): it is the correct tool.

Five saved programs: name a function configuration (High Pressure, 35 minutes, Natural Release 10 minutes) and save it with a custom label. Recall it in one touch. For households that make the same five dishes weekly: this eliminates repetitive programming each session. Not a high-ROI feature for casual users; genuinely time-saving for frequent users.

Verdict

The Instant Pot Pro is the right choice for: pressure cooker enthusiasts who cook 4+ times per week with varied recipes, households that will use the custom pressure settings and saved programs, and users who find touchscreen interfaces more comfortable than dials. For all other households: the Duo at $40 to $50 less delivers the same pressure cooking results with a simpler interface.
