Slow Cooker vs Instant Pot: Which Should You Buy?

TL;DR — A slow cooker does one thing simply and well: low, hands-off cooking over hours. An Instant Pot (multi-cooker) does that plus fast pressure cooking, sautéing, steaming, and rice — so it replaces a slow cooker for most people, at the cost of more complexity. The HomeWhisk team compared the two on function, speed, ease, and results. If you want maximum simplicity and set-and-forget all-day cooking, a slow cooker. If you want versatility and speed in one appliance, an Instant Pot. This guide helps you decide — and most people only need one.

The HomeWhisk editorial team researches kitchen equipment by analyzing manufacturer specifications, functions, and aggregated user reviews from major retailers and cooking communities. Our recommendations are based on what the products actually deliver, not what brands promise.

For this comparison, we analyzed the functions, cooking times, ease of use, and real-world feedback for both appliances. Here’s how slow cookers and Instant Pots differ, and which you actually need. For picks, see our best slow cooker and best instant pot guides.

What Each Appliance Is

Understanding what each one fundamentally is makes the comparison clear, because one is a subset of the other.

A slow cooker (Crock-Pot) is a simple appliance: a heated pot that cooks food at a low, steady temperature over a long time (4-10 hours). It has just a few settings — usually low, high, and warm — and does one thing: gentle, unattended long cooking. That simplicity is its whole identity. You add ingredients in the morning, set it, and come home to a finished meal.

An Instant Pot (multi-cooker) is a multi-function electric pressure cooker. It pressure cooks (fast), but also includes a slow-cook function, plus sauté, steam, rice, yogurt, and more. It’s essentially several appliances in one — a pressure cooker, a slow cooker, a rice cooker, and a sauté pan combined. It’s more capable but has more buttons and a learning curve.

The key relationship: the Instant Pot contains a slow cooker as one of its functions. So the real question isn’t “which cooks better” but “do you want simple single-purpose (slow cooker) or versatile multi-purpose (Instant Pot)?” The Instant Pot can do what the slow cooker does, plus much more — but the slow cooker does its one job with less complexity.

Speed: The Biggest Practical Difference

The starkest difference is time, and it cuts both ways depending on your schedule.

The slow cooker is slow by design — that’s the point. A stew takes 6-8 hours on low. This suits people who cook in the morning for the evening: prep before work, come home to dinner. But it requires planning ahead; there’s no fast option, and you can’t decide at 6 p.m. to make a slow-cooked meal for 7.

The Instant Pot is fast via pressure cooking — that same stew takes 30-45 minutes. It’s for people who want to cook dinner tonight without hours of waiting, or who forgot to plan ahead. Dried beans cook in an hour instead of soaking overnight; a whole chicken in 30 minutes; risotto in minutes.

The trade-off in results: many cooks feel long, slow braising develops flavor and tenderness in a way pressure cooking approximates but doesn’t perfectly replicate for certain dishes (some argue slow-cooked pulled pork or chili has an edge). The Instant Pot’s slow-cook function lets you choose the slow route when you have time, and pressure-cook when you don’t — flexibility the slow cooker can’t offer.

The scheduling question decides a lot: if your life fits “prep in the morning, eat at night,” a slow cooker works beautifully. If you want dinner fast and flexibly, the Instant Pot’s speed is a major advantage. Our best instant pot guide covers the versatile option; our best slow cooker guide the simple one.

Ease of Use and Versatility

The two appliances trade simplicity against capability, and which matters depends on the cook.

The slow cooker wins on simplicity. Three settings, no pressure, nothing to learn — add food, pick low or high, walk away. There’s no sealing valve, no pressure release, no risk or intimidation. For someone who wants the least possible complexity, or who’s nervous about pressure cooking, the slow cooker is foolproof. It’s also very forgiving — an extra hour rarely ruins anything.

The Instant Pot wins on versatility but asks more of you. It sautés (brown meat before pressure cooking in the same pot), pressure cooks, slow cooks, steams, makes rice and yogurt, and more — replacing several appliances and saving cabinet space. The cost is a learning curve: understanding the sealing valve, pressure release methods, and liquid requirements. Once learned it’s easy, but it’s more intimidating at first than a slow cooker.

Cleanup and design: both have removable inner pots for easy cleaning. The Instant Pot has a few more parts (sealing ring, lid) to clean and maintain. The slow cooker is simpler — just the pot and lid.

The honest trade-off: the slow cooker is simpler and less intimidating but does only one thing; the Instant Pot does far more but requires learning. If you value simplicity above all, slow cooker. If you value doing more with one appliance, Instant Pot — accepting the learning curve.

Which Should You Buy?

For most people the Instant Pot is the more practical single purchase, but the slow cooker has real appeal for some.

Buy an Instant Pot if you want versatility (pressure cook, slow cook, sauté, steam, rice — all in one), speed for weeknight cooking, and are willing to learn its basics. Since it includes a slow-cook function, it covers the slow cooker’s role too, making it the more capable choice for most kitchens and a space-saver. Start with our best instant pot guide.

Buy a slow cooker if you want maximum simplicity, do most of your cooking as morning-prep-for-evening set-and-forget meals, feel intimidated by pressure cooking, or specifically prefer long slow-braised results. It’s cheaper, simpler, and foolproof. See our best slow cooker guide.

Do you need both? Usually not — the Instant Pot’s slow-cook function makes a separate slow cooker redundant for most people. Buy both only if you frequently run two dishes at once (one slow-cooking all day while you pressure-cook another), or if you strongly prefer a dedicated slow cooker’s simplicity and results and also want pressure cooking. For most, one appliance suffices: the Instant Pot for versatility, or the slow cooker for pure simplicity.

Frequently Asked Questions

Should I buy a slow cooker or an Instant Pot?

For most people, an Instant Pot, because it includes a slow-cook function plus pressure cooking, sautéing, steaming, and rice — so it does everything a slow cooker does and much more, in one appliance. Choose a slow cooker instead if you want maximum simplicity, prefer morning-prep-for-evening set-and-forget cooking, feel intimidated by pressure cooking, or specifically favor long slow-braised results. The Instant Pot is more versatile; the slow cooker is simpler.

Does an Instant Pot work as a slow cooker?

Yes. Every Instant Pot includes a slow-cook function that replicates a traditional slow cooker, letting you do low-and-slow all-day cooking in the same appliance. This is why a separate slow cooker is redundant for most Instant Pot owners. Some cooks feel a dedicated slow cooker does slow braising slightly better, but for most purposes the Instant Pot’s slow-cook mode covers the role, adding pressure cooking and other functions on top.

Which is faster, a slow cooker or Instant Pot?

The Instant Pot is dramatically faster via pressure cooking — a stew that takes 6-8 hours in a slow cooker cooks in 30-45 minutes in an Instant Pot, and dried beans cook in about an hour without soaking. The slow cooker is intentionally slow (that’s its purpose), suiting morning-prep-for-evening meals. If you want dinner fast tonight or forgot to plan ahead, the Instant Pot’s speed is a major advantage; if you prefer to set it in the morning, the slow cooker’s pace is fine.

Is a slow cooker easier to use than an Instant Pot?

Yes. A slow cooker has just a few settings (low, high, warm), no pressure, and nothing to learn — add food, choose a setting, walk away. It’s foolproof and forgiving. An Instant Pot is more versatile but has a learning curve: the sealing valve, pressure-release methods, and liquid requirements take some getting used to. Once learned it’s easy, but the slow cooker is simpler and less intimidating from day one, especially for those nervous about pressure cooking.

Do slow-cooked meals taste better than pressure-cooked?

For some dishes, many cooks feel long slow braising develops deeper flavor and tenderness — pulled pork, chili, and some stews are often cited. Pressure cooking approximates this quickly and works excellently for most dishes, but the very long, gentle cooking of a slow cooker has its fans for certain recipes. The Instant Pot’s advantage is choice: use its slow-cook function when you have time and want that result, or pressure-cook when you’re short on time.

Do I need both a slow cooker and an Instant Pot?

Usually not. Since the Instant Pot includes a slow-cook function, it makes a separate slow cooker redundant for most people. Buy both only if you regularly cook two dishes at once (one slow-cooking all day while you pressure-cook another), or if you strongly prefer a dedicated slow cooker’s simplicity and slow-braised results while also wanting pressure cooking. For most kitchens, one appliance is enough — the Instant Pot for versatility or the slow cooker for simplicity.

The Bottom Line

The slow cooker and Instant Pot aren’t quite equals: the Instant Pot includes a slow-cook function plus pressure cooking, sautéing, steaming, and rice, so it does everything a slow cooker does and far more — at the cost of a learning curve. The slow cooker wins only on pure simplicity and set-and-forget all-day cooking. For most people, the Instant Pot is the smarter single buy and makes a separate slow cooker unnecessary; choose a slow cooker if you value simplicity above versatility. You rarely need both.
