Do You Need a Slow Cooker If You Have an Instant Pot?

The question is ownership, not which slow-cooks better

This is a specific question and it is worth keeping it specific. It parallels the one we work through in do you need both a rice cooker and a multicooker: you already own, or are about to buy, a multicooker that includes a Slow Cook function, so does it make sense to also own a dedicated slow cooker, or is that just a duplicate appliance eating your counter? It is not the head-to-head of which machine slow-cooks better — that is multicooker vs slow cooker. It is the ownership question, and the honest answer is that for most people a dedicated slow cooker is redundant, with a few specific exceptions where it genuinely is not. This guide is about telling which one you are before you spend on a second machine.

Yes, your Instant Pot really does slow-cook

Start with the honest baseline: an Instant Pot Duo has a Slow Cook program, and for the vast majority of people it slow-cooks well enough. You put the ingredients in, set it to slow-cook for the afternoon, and you come home to a braise or a chili that no one is going to complain about. We cover exactly how well it does this, and the one real quirk to know about, in can you slow-cook in an Instant Pot — the short version is that it works, with the caveat that the Instant Pot heats from the base rather than wrapping the pot the way a classic slow cooker does, so some cooks nudge the setting up a notch. So the starting assumption should be that you probably do notneed a second machine. If you already own an Instant Pot and you slow-cook occasionally, a dedicated slow cooker really is a duplicate, and the honest advice is to skip it and save the counter space and the money. A guide that told everyone to buy both would be selling, not advising. Most of the reasons to own both only start to matter in specific situations — so the honest first question is not “which slow-cooks better” but “do any of these situations describe me.”

Where a dedicated slow cooker still earns its place

There are four real ones, and they are worth naming precisely because the rest of the time the answer is no. The first is gentle, genuinely low all-day heat. Some cooks prefer the way a classic slow cooker wraps a low, even heat all the way around the crock for eight or ten hours, and find it more forgiving on a long, unattended braise than an Instant Pot heating from its base. It is a preference rather than a rule — plenty of people cannot tell the difference — but if you are someone who slow-cooks all day, every week, and cares about that gentleness, a dedicated pot is built for exactly that one job. The second is the Crock-Pot Cook & Carry's locking travel lid. It clamps down so the whole 6-quart pot travels to a potluck, a tailgate or a family dinner without sloshing — a genuinely useful thing an Instant Pot, with its heavy lid and exposed base, simply does not do. If you bring a hot dish to gatherings, that lid alone can justify the second machine. The third is running two pots at once: if the slow cooker is handling the chili on the counter, your Instant Pot is free to pressure-cook the rice, the beans or a second dish at the same time — the same parallel-cooking argument that convinces most people who end up owning two machines of any kind. And the fourth is capacity: the Ninja PossibleCooker PRO is an 8.5-quart pot, larger than a standard 6-quart Instant Pot, so for the biggest slow-cooked batches — a Sunday chili for a crowd, a batch of pulled pork that becomes three nights of leftovers — it holds more in one load than your multicooker can.

The case for keeping it to one machine

The argument against a second pot is just as real, and for most kitchens it wins. A slow cooker is another appliance to find counter or cupboard spacefor, and in a small kitchen that is a genuine cost — an appliance you have to dig out of a deep cupboard every time is one you will use less than you imagined when you bought it. It is also money spent on a function you already own: your Instant Pot's Slow Cook mode is right there, included, already paid for. If you slow-cook occasionally, do not travel with a hot dish, rarely need two pots going at once, and never cook a batch bigger than your Instant Pot holds, then none of the four reasons above apply to you and a dedicated slow cooker is simply a duplicate. The lowest draw and the travel lid are real advantages of the Crock-Pot, but they only matter if you will actually use them — and whether the slow-cooker category earns a spot in your kitchen at all is the broader question we take on in are slow cookers worth it.

If you do decide to own both, buy cheap

One thing tilts this decision in a helpful direction: if any of the four reasons genuinely applies to you, the second machine does not have to be an expensive one. A dedicated slow cooker is among the cheapest appliances in the kitchen, and the Crock-Pot Cook & Carry in particular draws just 240 W — the lowest of any cooker on this site — so it is cheap to buy and cheap to run all day long. That changes the calculus. You are not weighing a slow cooker against the full price of another multicooker; you are adding a low-cost, low-draw, single-purpose pot for the one specific job your Instant Pot does not do as gracefully — the gentle all-day heat, or, more concretely, the locking travel lid. The exception is capacity: if you cook for a crowd and want the most slow-cooking volume in one load, the step up is the 8.5-quart Ninja PossibleCooker PRO rather than a bigger Instant Pot, because it is built around slow-and-large cooking and drops the pressure mechanism you may never use. Either way, the point holds: when a second machine is justified here, it is a modest and targeted purchase, not a second flagship — which is part of why owning both is a reasonable call for the households the four reasons actually describe, and a waste of counter space for everyone else.
