Crockpot vs Instant Pot: Which One Actually Saves You More Time on a Weeknight
I compared real cook times, not marketing claims, to find out which appliance actually gets dinner on the table faster.
I own both a slow cooker and an Instant Pot, and for years I genuinely could not tell you which one actually saved me more time on a weeknight. The Instant Pot box promises speed. The slow cooker promises convenience. Neither of those words means the same thing when you are standing in your kitchen at 5:30 trying to figure out what to make. So I dug into the actual numbers, including the parts most marketing conveniently leaves out, and figured out which appliance really wins depending on what your weeknight actually looks like.
The Numbers Everyone Quotes Are Missing Something Important
If you search for Instant Pot versus slow cooker comparisons, you will see charts like this one. A beef stew takes 25 to 30 minutes in an Instant Pot compared to 8 hours on low or 4 hours on high in a slow cooker, and a pork shoulder takes 90 minutes in an Instant Pot compared to 6 to 8 hours in a slow cooker, according to Temecula Blogs. On paper, that makes the Instant Pot look like an obvious win.
Here is what those numbers do not include. An Instant Pot needs time to actually reach pressure before the countdown even starts, and it needs time to release that pressure afterward before you can open the lid. Neither of those steps shows up on the recipe's stated cook time.
What Natural Release Actually Costs You
This is the part that changed my thinking the most. According to Pressure Cooking Today, natural pressure release typically takes anywhere from 5 to 30 minutes depending on the ingredients and how much liquid is in the pot, while quick release can happen in as little as 1 to 5 minutes once you manually flip the valve. The catch is that food keeps cooking during natural release, since the pot is still hot and still sealed. For large cuts of meat like a pork shoulder or a whole chicken, you generally want to let the pressure release naturally for tenderness, which means that 90 minute pulled pork recipe can realistically stretch closer to 100 or 110 minutes once you account for coming up to pressure and releasing it afterward.
That is still dramatically faster than 6 to 8 hours in a slow cooker. But it means the honest gap is smaller than the headline numbers suggest, and if you forget to build in that extra 15 to 20 minutes when planning dinner, you can end up just as rushed as if you had used the slow cooker.
Total Time Including Everything, For Three Real Meals
I found a breakdown that actually accounts for the full process from start to finish, including pressurization, rather than just the pressure cooking window. According to Smart Home Explorer, here is how three common dinners compare when you measure total real time:
- Beef stew for four servings: 45 minutes total in an Instant Pot Pro Plus, compared to 480 minutes, or 8 hours, in a slow cooker.
- Pulled pork for six servings: 90 minutes total in an Instant Pot, compared to 600 minutes, or 10 hours, in a slow cooker.
- Chicken soup for four servings: 30 minutes total in an Instant Pot, compared to 360 minutes, or 6 hours, in a slow cooker.
Even with the full pressurization and release time baked in, the Instant Pot wins on raw speed by a wide margin every single time. If your only question is which appliance gets food on the table faster from a cold start, the Instant Pot is not close.
But Speed Is Not the Only Kind of Time That Matters
Here is where I think most comparisons miss the actual point of a busy weeknight. The Instant Pot wins on active cook time, but it requires you to be home and ready to start cooking when that clock begins. A slow cooker wins on a completely different axis, which is that it lets you do the work in the morning before you leave for the day, and dinner is simply done and waiting when you walk in the door at six in the evening.
If I put beef stew ingredients into my slow cooker at 7am before work, the 8 hour cook time is irrelevant to my evening, because I am not standing around waiting for it. My actual active time on a weeknight is close to zero, since I already did the fifteen minutes of chopping and browning that morning. Compare that to the Instant Pot's 45 minutes, and suddenly the slow cooker is the faster option for my actual evening, even though it is objectively the slower cooking method.
This is really a question about when you want to spend your time, not just how much of it you spend.
Energy Cost Is a Smaller Factor Than People Expect
I was curious whether the Instant Pot's speed also meant it was cheaper to run, and the answer surprised me. According to the same Smart Home Explorer data, an Instant Pot averaged about $0.10 per meal compared to $0.15 for a slow cooker across six sample meals, making the Instant Pot roughly 33 percent cheaper per meal. But the actual dollar amount is tiny. The guide states plainly that "the annual difference between them is just $18.25 at one meal per day," which tells me the real argument between these two appliances has never really been about electricity. It is entirely about time.
Interestingly, pulled pork actually cost slightly more in the Instant Pot at $0.24 per meal compared to $0.19 in the slow cooker, since the Instant Pot's higher wattage during active pressure cooking outweighed its shorter total time for that particular dish. Both appliances save somewhere between 83 and 89 percent on electricity compared to conventional stovetop or oven cooking, so honestly, either one is a reasonable choice if energy use is your main concern.
My Honest Verdict for a Real Weeknight
If your weeknight problem is that you get home at 5:30 and need dinner by 6:15, the Instant Pot wins clearly. A chicken soup or a quick stew can realistically go from raw ingredients to a finished meal in 30 to 45 minutes, pressurization and release included, and there is no other appliance that gets you there faster short of a stovetop dish you are actively babysitting the whole time.
If your weeknight problem is that you do not have time in the evening at all, whether because of a commute, kids' activities, or just wanting to walk in the door to a finished meal, the slow cooker wins, because it moves all of your active effort to the morning when you have more flexibility. The 8 hour cook time is not a cost to you personally, since you are not standing next to it.
I have landed on using both depending on the week. If I know I will be home and hungry at a predictable time, the Instant Pot gets the job done fast. If I know my evening will be chaotic and I want dinner already finished before I even think about it, the slow cooker goes on before I leave in the morning. Neither one is universally faster. They are just fast in different parts of your day.
