How long to cook carrots and potatoes in an Instant Pot depends on whether you’re cooking them together or separately, and what texture you’re aiming for.
For tender, fork-soft carrots and potatoes cooked together, you’re looking at around 3 to 5 minutes at high pressure.
But there’s more nuance to it than just tossing them in and pressing a button.
If you’ve been wondering how long to cook carrots and potatoes in an Instant Pot without turning them into mush, this post will walk you through the exact times, the best methods, and a few tips so your veggies come out perfectly every time.
The cooking time for carrots and potatoes in an Instant Pot can vary based on how you cut them, whether you’re using a steamer basket or cooking them directly in liquid, and the size of your pieces.
Let’s break it all down so you can nail this the first time.
How Long to Cook Carrots and Potatoes in an Instant Pot
When you cook carrots and potatoes together in an Instant Pot, the key is getting both vegetables to finish at the same time without one turning to baby food while the other stays firm.
Carrots and potatoes actually have slightly different cooking times, so the trick is in how you prep them.
Here are the general guidelines for how long to cook carrots and potatoes in an Instant Pot:
1. Carrots and Potatoes Together (Steamed)
If you’re cooking diced carrots and cubed potatoes together in a steamer basket with a cup of water at the bottom, set your Instant Pot to high pressure for 3 to 4 minutes.
Do a quick release when the timer goes off.
Small dice will be tender in about 3 minutes, while larger chunks might need 4 to 5 minutes.
This is the fastest way to cook carrots and potatoes in an Instant Pot when you want them as a side dish.
2. Carrots and Potatoes for Mashing
If you’re making mashed carrots and potatoes, you can cook them together for 5 to 7 minutes on high pressure.
Cut both into roughly equal-sized chunks so they cook evenly.
Add enough water or broth to cover them, then let the Instant Pot do its thing.
Once done, quick release, drain, and mash with butter, cream, or whatever you like.
3. Carrots Alone vs. Potatoes Alone
Sometimes you might want to cook them separately, and that’s fine too.
Carrots alone usually take 2 to 4 minutes on high pressure depending on thickness.
Potatoes alone, cut into chunks, take about 5 to 7 minutes.
So when you’re figuring out how long to cook carrots and potatoes in an Instant Pot together, you’re basically splitting the difference and adjusting your cuts so they finish at the same time.
4. Whole vs. Chopped Matters
Whole carrots and whole potatoes will take much longer — sometimes 10 to 15 minutes or more.
If you’re cooking carrots and potatoes in an Instant Pot as whole pieces, you’ll need to add several minutes to the time.
But honestly, chopping them into chunks is faster and gives you more consistent results.
A good rule of thumb: the smaller the pieces, the shorter the cook time for carrots and potatoes in an Instant Pot.
Tips for Perfect Carrots and Potatoes in an Instant Pot
Getting the timing right for how long to cook carrots and potatoes in an Instant Pot is one thing, but a few extra tips can make the difference between good and great.
1. Cut Them the Same Size
This is probably the most important tip.
If your carrots are in thin coins and your potatoes are in big wedges, they won’t cook at the same rate.
Aim for pieces that are roughly 1 to 1.5 inches across for both.
That way, when you cook carrots and potatoes in an Instant Pot, everything finishes together.
2. Use a Steamer Basket or Trivet
Cooking carrots and potatoes in an Instant Pot with a steamer basket keeps them out of the water, which prevents them from getting waterlogged.
Just add a cup of water to the inner pot, place the basket on top, and load in your veggies.
This method gives you fluffy potatoes and bright, tender carrots every time.
3. Don’t Skip the Quick Release
For vegetables, a quick release is usually best.
Letting the pressure come down naturally can overcook carrots and potatoes in an Instant Pot, especially if they’re cut small.
So as soon as the cook time ends, carefully flip the valve and release the steam.
4. Season After Cooking
Salt and pepper can go in before cooking, but delicate herbs and spices are better added after.
When you cook carrots and potatoes in an Instant Pot, the high pressure can dull some flavors.
So taste and adjust seasoning once they’re done.
A little butter or olive oil tossed in at the end goes a long way too.
5. Adjust for Altitude
If you live at a high altitude, you’ll need to add a minute or two to whatever time you settle on.
The general rule is to increase cooking time by about 5 percent for every 1,000 feet above sea level.
So keep that in mind when planning how long to cook carrots and potatoes in an Instant Pot.
Common Mistakes When Cooking Carrots and Potatoes in an Instant Pot
Even with the right timing, a few common mistakes can throw off your results.
1. Overfilling the Pot
The Instant Pot needs room for steam to circulate.
If you cram it full, your carrots and potatoes won’t cook evenly, no matter how long you set the timer.
Fill it no more than two-thirds of the way.
2. Forgetting the Liquid
You always need at least one cup of water or broth to build pressure.
Without enough liquid, the Instant Pot won’t come to pressure, and your veggies won’t cook at all.
So when you cook carrots and potatoes in an Instant Pot, don’t skip the liquid.
3. Not Accounting for Carryover Cooking
Even after you release the pressure, the residual heat keeps cooking your vegetables for a minute or two.
If you’re aiming for crisp-tender, it’s better to err on the side of slightly undercooking them.
That way, when you cook carrots and potatoes in an Instant Pot, they don’t turn mushy while you’re waiting to serve.
So, How Long to Cook Carrots and Potatoes in an Instant Pot?
How long to cook carrots and potatoes in an Instant Pot comes down to 3 to 5 minutes on high pressure for diced pieces cooked together, with a quick release.
If you’re mashing them, go for 5 to 7 minutes.
Just remember to cut them evenly, use a steamer basket, and adjust for altitude if needed.
Once you get the hang of it, cooking carrots and potatoes in an Instant Pot becomes second nature, and you’ll have a fast, healthy side dish ready in minutes.
So go ahead and give it a try — your future self will thank you when dinner’s on the table in under 20 minutes.
