I bought my first slow cooker in 2011 for $24 at a Walmart clearance sale. Used it maybe four times, then shoved it to the back of the cabinet where it spent three years collecting a thin film of grease and regret. When the Instant Pot craze exploded around 2016-2017, I was deeply skeptical—burned before, literally and figuratively—but I caved anyway and bought the Duo 6-quart.
Here’s what nobody bothers telling you upfront: both appliances are genuinely useful, just for completely different reasons. Grabbing the wrong one for your actual lifestyle doesn’t just drain your wallet. It drains the mental energy you spend feeling guilty every single time you open that cabinet.
So if you’re stuck in the slow cooker vs instant pot weeknight dinners debate right now, let me spare you the two months of Reddit rabbit holes I personally endured.
The Core Time Question (And Why It’s Trickier Than You Think)
People see “slow cooker” and assume it devours their time. People see “Instant Pot” and assume it rescues it. Neither assumption holds up particularly well.
A slow cooker runs 6-8 hours on low. But your active involvement? Maybe 15 minutes in the morning. You dump everything in, twist a knob, walk out the door. When you drag yourself home at 6pm, dinner’s already done. No hovering, no babysitting. That’s a genuinely undervalued thing.
The Instant Pot cooks a beef stew in about 35 minutes under pressure. Sounds like a landslide. But factor in 10-15 minutes to reach pressure and another 15-20 minutes for natural release, and your real timeline lands somewhere around 60-75 minutes. Still faster than an oven, sure. Just not the 35-minute miracle the recipes keep promising.
Actual Cost Comparison: Electricity and Ingredients
Let’s talk money, because this actually matters.
A standard slow cooker pulls about 75-150 watts on low. Run it 8 hours and you’ve used roughly 0.6-1.2 kWh. At the average US electricity rate of $0.16 per kWh in 2023 (per the EIA), that’s under 20 cents per meal. Genuinely cheap.
The Instant Pot runs at 700-1000 watts but only for 30-60 minutes at a stretch. So you’re looking at similar or slightly lower electricity cost per meal—maybe 10-15 cents. Basically a wash.
Where things actually diverge is ingredients. Slow cookers were practically engineered for cheap cuts: chuck roast, chicken thighs, dried beans, pork shoulder. The stuff that gets better the longer it sits in moist, low heat. A 3-pound chuck roast from Aldi runs about $8-10 and feeds four people without complaint. Hard to beat.
The Instant Pot handles cheap cuts too, but it tempts you toward convenience in ways the slow cooker doesn’t—jarred sauces, pre-cut vegetables, little shortcuts that quietly inflate your grocery bill over time. Not a criticism of the machine itself. Just something worth watching.
Morning Person vs Evening Person: This Is the Real Decision
Here’s what I actually think the whole thing comes down to: when do you have five spare minutes?
If you’re a morning person who can pull things together before work, a slow cooker fits your life almost perfectly. Something like slow cooker white chicken chili—two cans of beans, a pound of chicken breast, a jar of salsa verde, some cumin—takes maybe 12 minutes to assemble at 7am and is ready when everyone’s hungry.
But if mornings are pure chaos (kids, commutes, the general horror of existing before 8am), you won’t do the prep. You’ll skip it. Then you’ll order pizza. And your slow cooker will become my 2011 slow cooker.
Evening people, or anyone with even a little flexibility in the late afternoon, tend to actually use the Instant Pot more consistently. Because 6pm isn’t too late to start something that’ll be done in under an hour.
Which Recipes Actually Work Better in Each
Not everything belongs in a slow cooker, and it’s worth being honest about that. Pasta goes mushy. Fish basically disintegrates. Anything needing a quick sear or a crispy finish simply cannot happen inside a ceramic crock.
Slow cooker wins with: pulled pork, pot roast, chili, soups, dried beans, overnight oatmeal, braised greens. Anything that genuinely improves with long, gentle, uninterrupted moist heat.
Instant Pot wins with: risotto (honestly, this is borderline magical—done in 7 minutes), hard-boiled eggs, dried beans in under an hour with no soaking, bone broth, rice, quick curries. And anything where you completely forgot to defrost the chicken. You can cook frozen chicken breast in an Instant Pot. You absolutely cannot do that safely in a slow cooker.
The sauté function also matters more than people give it credit for. You can brown your onions and garlic right in the pot before sealing it up. That one step adds flavor depth that you’d almost certainly skip if you were using a slow cooker—and you feel it in the finished dish.
The Cleanup Reality Nobody Wants to Talk About
Slow cooker cleanup: rinse the ceramic insert, soak it if something stuck, wipe the lid. Done in five minutes, maybe less.
Instant Pot cleanup: the inner pot, the sealing ring (which absorbs smells with alarming enthusiasm—mine permanently carries a ghost of the tikka masala I made in January 2022), the steam release valve, the lid with its various components. Not difficult, but not quick either.
And the sealing ring issue is genuinely real. You’ll eventually want a second one reserved strictly for sweet dishes. Budget another $8-12 for that sooner rather than later.
The Verdict on Savings Over a Full Year
I tracked my cooking costs loosely across six months in 2023. Using the slow cooker roughly twice a week for cheap-cut meals, my average weeknight protein cost ran about $2.10 per person. With the Instant Pot, it crept up to $2.80 per person—because when time felt short, I defaulted to easier and pricier ingredients almost automatically.
Small gap. But across a full year, for a family of four? That adds up to something real.
Bottom Line
Here’s the thing nobody includes in these comparisons: the appliance that saves you the most time and money isn’t the faster one or the cheaper one. It’s whichever one you’ll actually use with any consistency. A slow cooker sitting unused saves you nothing. An Instant Pot you’re vaguely intimidated by saves you nothing either.
But there’s one more thing—slow cookers carry a psychological advantage that’s genuinely underrated. Because you set them up in the morning, dinner feels handled for the rest of the day. That low-grade background hum of “what are we even eating tonight” just disappears. The Instant Pot, fast as it is, cannot give you that particular relief.
Frequently Asked Questions
Is an Instant Pot worth it if you already have a slow cooker?
Probably yes, if you find yourself regularly skipping the morning prep. The Instant Pot hands you a same-evening option when mornings fall apart. Having both isn’t overkill if you’re actually using both.
Can an Instant Pot replace a slow cooker entirely?
Technically it has a slow cook mode, but honestly? It’s mediocre. The heat distribution just isn’t the same. If slow cooking is your primary thing, keep your dedicated slow cooker.
Which is better for meal prepping on Sunday?
Instant Pot wins here without much contest. You can cycle through multiple batches of grains, beans, and proteins in a single afternoon. The speed lets you knock out three or four things in roughly the time a slow cooker handles one.
What’s the best starter slow cooker recipe for weeknights?
Pulled chicken. Toss chicken thighs in with a cup of chicken broth, garlic powder, paprika, and a splash of apple cider vinegar. Eight hours on low. Shred it, put it on literally anything. Under $6 for four servings, and almost no way to mess it up.
