Instant 20-Cup vs Zest 8-Cup: Which Fits Your Meals and Cleanup?

Choose the Instant 20-Cup for sauté-to-slow-cook meals or a dishwasher-permitted cooking pot and removable inner lid cover. Choose Zest 8 for a rice, oatmeal and steaming routine when its named Oatmeal control appeals and you are happy to hand-wash the pot and wipe the fixed lid.

The buying question

Do you need a sauté-to-slow-cook workflow or dedicated oatmeal controls, and which pot-and-lid care routine will you follow?

The Instant 20-Cup supports sautéing followed by slow cooking and permits dishwasher washing of its pot and removable inner lid cover. Zest 8 offers a named oatmeal control, but its manual calls for hand-washing the pot and wiping its fixed lid.

Quick verdict

Choose Instant Zest 8-Cup (140-5000-01) if

  • You want the labelled Oatmeal control with adjustable cooking time.
  • Its rice and steam controls cover your meals, and you accept hand-washing the pot.

When the recommendation changes
  • A dishwasher-permitted cooking pot is non-negotiable: choose the Instant 20-Cup even if oatmeal is common.
  • If you already sauté separately and are content with hand-washing, decide by the controls you will actually use and the current offers.

The differences that matter

Meal Program Workflow

Instant Pot 20-Cup Multigrain Cooker (140-5003-01)

The 140-5003-01 manual gives a Sauté-to-Slow-Cook sequence: sauté, press Cancel, optionally deglaze the pot, then start Slow Cook.[1]

Instant Zest 8-Cup (140-5000-01)

Zest 8 provides White Rice, Brown Rice, Quinoa, Oatmeal, Steam and Keep Warm controls; Oatmeal and Steam cooking times are adjustable. The Zest family manual explicitly assigns Sauté to Zest 20C only.[2, 3]

What this changes: Choose the Instant 20-Cup for meals that use sautéing followed by slow cooking in its pot. Choose Zest 8 when its named oatmeal and rice/steam controls cover your routine and you do not need an on-appliance Sauté control. This is a control-workflow choice, not a food-quality comparison.[1, 2, 3]

The better fit depends on your priorities

Cooking Pot And Lid Care

Instant Pot 20-Cup Multigrain Cooker (140-5003-01)

The cooking pot and steam basket may be hand-washed or put in the dishwasher; the removable Inner Lid Cover may go on the top rack. The cooker base and outer lid are wiped with a barely damp cloth.[1]

Instant Zest 8-Cup (140-5000-01)

The manual places the inner pot under Hand Wash and instructs you to wipe the lid and base. Its lid is not removable. The steamer tray, measuring cup, rice spoon and condensation collector are dishwasher-safe.[2]

What this changes: If putting the cooking pot and removable inner cover in the dishwasher matters, choose the Instant 20-Cup. Zest 8 suits a routine that includes hand-washing the pot and wiping the fixed lid. Neither whole appliance goes in the dishwasher, and these instructions do not establish time saved or coating longevity.[1, 2]

The better fit depends on your priorities

Best for your routine

Sauté ingredients before a slow-cooked meal

Best fit: Instant Pot 20-Cup Multigrain Cooker (140-5003-01)

Based on listed features, not comparative testing.

The Instant 20-Cup provides that documented sequence. You must select the successive programs yourself; it is not an automatic sauté-to-slow-cook cycle.

A regular oatmeal routine with hand-washing already part of cleanup

Best fit: Instant Zest 8-Cup (140-5000-01)

Based on listed features, not comparative testing.

Zest 8 provides a named, time-adjustable Oatmeal setting. Accept its hand-wash pot and fixed-lid care; this does not mean the Instant 20-Cup cannot prepare oats.

Dishwasher washing of the cooking pot is essential

Best fit: Instant Pot 20-Cup Multigrain Cooker (140-5003-01)

Based on listed features, not comparative testing.

The Instant 20-Cup manual permits it, while Zest 8’s manual puts the pot under Hand Wash. The removable inner cover is top-rack-safe; the base and outer lid still need wiping.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

If the Instant 20-Cup costs more, pay for its sauté-to-slow-cook workflow or dishwasher-permitted pot only if you will use them. If Zest 8 costs more, decide whether its named Oatmeal control is worth that difference to you; neither price establishes better cooking results.

There is insufficient price-history evidence here to recommend buying now or waiting.

Limitations

  • This compares the US Instant 140-5003-01 with Zest 8-Cup 140-5000-01. The Zest 20-Cup discussed in the family manual is a different model.
  • NFM’s Zest 8 listing describes a dishwasher-safe pot, conflicting with the manufacturer’s Hand Wash instruction. Follow the manufacturer’s manual; no coating or revision difference has been established to explain the conflict.
  • No hands-on comparison establishes better taste, texture, cooking speed or durability. This article does not assess carbohydrate reduction or nutritional benefits.

Questions shoppers ask

Can the whole lid go in the dishwasher on the Instant 20-Cup?

No. The manual permits top-rack washing of the removable Inner Lid Cover, not the outer lid or electrical base. Refit that cover before cooking. For either cooker, unplug it and let it cool before cleaning, never immerse the appliance, and dry the pot’s exterior before putting it back.

Is Zest 8 the same as the Zest 20-Cup mentioned in shared manuals?

No. The shared manual labels Sauté as Zest 20C-only. Do not transfer that control to Zest 8, or confuse the Zest 20C with the 140-5003-01 Instant 20-Cup compared here.
