Introduction
When a kitchen appliance earns a strong enough reputation, the natural question becomes what comes next — how does a product that already does a great deal manage to offer something meaningfully more without simply adding functions for their own sake. The Instant Pot Duo Plus 9-in-1 represents one answer to that question, taking the foundation established by the original Duo and expanding it with additional cooking programs and refinements that address a broader range of cooking needs.
Where the standard Duo offered seven functions, the Duo Plus steps that up to nine, adding cooking programs that extend the appliance’s versatility into territory the base model doesn’t cover. For those already familiar with the Instant Pot ecosystem, the Duo Plus represents an upgrade path. For those coming to multicooker cooking for the first time, it offers a more fully featured starting point. This article takes a detailed look at what the Duo Plus 9-in-1 brings to the kitchen, how its additional capabilities translate into practical use, and what’s worth considering before choosing between this model and others in the lineup.
Key Features
Nine Cooking Functions
The Duo Plus expands on the standard Duo’s seven functions by adding two additional cooking programs, bringing the total to nine. The core functions — pressure cooking, slow cooking, rice cooking, steaming, sautéing, yogurt making, food warming, and sterilizing — are retained from the base model, with the additional programs addressing cooking needs not covered in the standard configuration. This expanded function set makes the Duo Plus a more comprehensive cooking tool for households that regularly prepare a wider variety of dishes.
Pressure Cooking with Enhanced Programs
Like other models in the Instant Pot lineup, pressure cooking sits at the center of the Duo Plus’s capabilities. The elevated pressure environment significantly reduces cooking times for proteins, legumes, grains, and other ingredients that typically require extended preparation, making it possible to prepare dishes in a fraction of the time conventional methods would require. The Duo Plus’s pressure cooking programs include refinements that provide more precise control over pressure levels and cooking parameters compared to the base model.
Cake and Egg Programs
Among the additions that distinguish the Duo Plus from the standard Duo are dedicated programs for cake and egg cooking. The cake program is designed to handle steamed and pressure-cooked cake preparations, which produce a moist, dense texture distinct from oven-baked cakes — a style that has a long tradition in various culinary cultures and has found a new audience through Instant Pot cooking. The egg program addresses one of the most popular Instant Pot use cases, providing a dedicated setting for cooking eggs to different levels of doneness consistently and efficiently.
Sterilizing Function
The sterilizing function, which allows the appliance to be used for sterilizing baby bottles, canning jars, and kitchen equipment, adds utility that extends beyond purely food preparation. For households with infants or those who do home preserving and canning, this function addresses a practical need without requiring a separate dedicated appliance.
Sous Vide Capability
Some versions of the Duo Plus include a sous vide function, which involves cooking food sealed in a bag submerged in precisely temperature-controlled water over an extended period. Sous vide is a technique that originated in professional kitchens and is associated with exceptionally precise temperature control and highly consistent results, particularly for proteins. The inclusion of this function in a consumer multicooker makes a professional cooking technique accessible at home without dedicated sous vide equipment.
6-Quart Capacity
The 6-quart size offers a versatile capacity well-suited to households of two to six people. It’s large enough to handle whole chickens, larger roasts, and batch cooking while remaining compact enough for everyday use and practical storage in most kitchen setups.
Stainless Steel Inner Pot
The inner cooking pot is constructed from stainless steel, offering durability and easy cleaning without the maintenance concerns associated with non-stick coatings. Stainless steel is non-reactive with acidic ingredients and handles the full range of cooking functions — including sautéing at higher temperatures — without degrading over time.
Updated Control Panel and Display
The Duo Plus typically features a more refined control panel compared to the standard Duo, with clearer indicators and a display that provides more information about the current cooking status. For those who find the original Duo’s interface sufficient, this may be a minor consideration, but for those who prefer more visibility into the cooking process, the updated display is a practical improvement.
App Integration with Over 800 Recipes
Like other models in the lineup, the Duo Plus includes access to an app with over 800 guided recipes specifically developed for Instant Pot cooking. This resource is particularly valuable for new users working through the learning curve of pressure cooking and exploring what the appliance’s various functions can produce.
Multiple Safety Systems
The appliance incorporates the same range of safety mechanisms found throughout the Instant Pot lineup, including lid locking, pressure regulation, and overheat protection. These systems are designed to make pressure cooking approachable for home users who may be unfamiliar with the technique.
How It Can Be Used
Everyday Pressure Cooking
The most commonly used function for most households remains pressure cooking, where the time savings are most dramatic and most immediately practical. Weeknight proteins, soups, stews, and grain dishes that would otherwise take an hour or more can often be ready in significantly less time, making home cooking feasible on evenings when time is genuinely limited.
Consistent Egg Preparation
The dedicated egg program addresses what has become one of the most talked-about Instant Pot applications — cooking eggs to a precise level of doneness consistently and efficiently. Hard-boiled eggs that peel easily, soft-boiled eggs with jammy yolks, and other egg preparations benefit from the controlled environment that a dedicated egg program provides.
Steamed and Pressure-Cooked Baking
The cake program opens up a category of cooking that many home cooks haven’t explored — pressure-cooked and steamed baked goods. Cheesecakes in particular have become a popular Instant Pot preparation, benefiting from the moist, steam-rich environment to produce a dense, creamy texture that differs from oven-baked versions. The dedicated program provides the appropriate settings for these preparations without requiring manual configuration.
Slow-Cooked Meals for Busy Days
The slow cooker function suits a different rhythm of cooking — setting a meal to cook low and slow before leaving for work and returning to a finished dish in the evening. This approach works particularly well for braised meats, hearty soups, and dishes that develop deeper flavor through extended gentle cooking.
Sous Vide for Precision Cooking
For those interested in exploring professional cooking techniques at home, the sous vide function opens up a method that produces exceptionally consistent results for proteins in particular. Cooking a steak, chicken breast, or fish fillet at a precisely controlled temperature for an extended period produces results that are difficult to achieve reliably through conventional methods.
Batch Cooking and Meal Preparation
The 6-quart capacity supports cooking larger quantities at once, making the Duo Plus a practical tool for meal prepping. Cooking proteins, grains, and legumes in bulk at the beginning of the week and portioning them for use across multiple meals is one of the more efficient uses of a multicooker.
Yogurt Making
The yogurt function maintains the steady low temperature needed for fermentation, making homemade yogurt a straightforward preparation rather than a technically demanding project. Adjusting fermentation time allows for customization of the final product’s tartness and texture.
Sterilizing Baby Equipment and Kitchen Items
For households with infants, the sterilizing function provides a practical way to sterilize bottles and feeding equipment without a dedicated sterilizer. For those who do home preserving, it offers a way to sterilize jars before use.
Who It May Be Suitable For
Those Who Want More Than the Standard Duo Offers
The Duo Plus is most naturally suited to those who have considered the standard Duo but find its seven functions slightly short of what they need, particularly those interested in the egg program, cake function, or sous vide capability that the base model doesn’t include.
Households with Diverse Cooking Interests
Families or individuals who cook across a wide range of cuisines and techniques will find the broader function set of the Duo Plus more relevant than those whose cooking habits are relatively focused and consistent. The additional programs are most valuable when they address cooking needs that actually exist in a household’s regular rotation.
Those Interested in Exploring New Cooking Techniques
The sous vide function in particular opens up a cooking method that many home cooks haven’t previously had access to without dedicated equipment. For those curious about this technique, having it available within a multicooker they’re already using for other purposes provides a low-barrier introduction.
Households with Infants or Those Who Home Preserve
The sterilizing function adds meaningful utility for specific household situations — families with young children who need to regularly sterilize feeding equipment, or those who do home canning and preserving who need to sterilize jars.
Experienced Instant Pot Users Looking to Upgrade
Those who already own an earlier or more basic Instant Pot model and have found themselves wanting more specific programs or greater control may find the Duo Plus a natural upgrade that builds on existing familiarity with the platform.
Important Things to Consider
Evaluating Whether Additional Functions Are Genuinely Needed
The most important consideration when choosing between the Duo and the Duo Plus is an honest assessment of whether the additional functions address actual cooking needs rather than theoretical ones. The egg and cake programs are useful for those who regularly prepare these items, but represent unnecessary complexity for those who don’t. Choosing based on actual cooking habits rather than the appeal of having more options available is the more practical approach.
Price Difference Relative to the Standard Duo
The Duo Plus carries a higher price than the standard Duo, reflecting its expanded feature set. Whether that price difference is justified depends entirely on how many of the additional functions will realistically be used. For households that will genuinely use the extra programs regularly, the premium represents good value. For those whose cooking habits are already well-served by the standard Duo’s function set, the additional cost may not be warranted.
Same Learning Curve as Other Instant Pot Models
Those new to pressure cooking will encounter the same learning curve with the Duo Plus as with any other Instant Pot model — understanding pressure release methods, liquid requirements, and timing adjustments for different types of food. The additional functions don’t significantly complicate this initial learning process, but they do add more to explore once the basics are established.
Sous Vide Requires Additional Equipment
Using the sous vide function requires food-safe bags and ideally a vacuum sealer for optimal results, which represents an additional equipment investment for those who don’t already have these items. Factoring in this consideration is relevant if sous vide is a primary motivation for choosing the Duo Plus over the standard model.
Storage and Countertop Space
The physical footprint of the Duo Plus is similar to the standard Duo at the same capacity, so those already planning for an Instant Pot’s storage requirements won’t need to make additional accommodations for the upgraded model.
Comparison of General Categories
