Potatoes and carrots usually need to simmer for about 15 to 20 minutes when cut into bite-sized cubes.
If you’re wondering how long to simmer potatoes and carrots, the answer really depends on how big you cut them, but that 15 to 20 minute window is a solid starting point.
Simmering potatoes and carrots together is one of those simple kitchen tasks that trips up a lot of home cooks.
One minute they’re rock hard, and the next they’re falling apart into mush.
So if you’ve been asking how long to simmer potatoes and carrots, you’re in the right place.
In this post, we’ll break down the exact simmer times for potatoes and carrots, what changes those times, and how to nail that perfect tender-but-not-mushy texture every single time.
Let’s get cooking.
How Long to Simmer Potatoes and Carrots Together
When you simmer potatoes and carrots together, timing is everything, and here’s what you need to know.
1. The 15 to 20 Minute Rule
For diced potatoes and carrots cut into roughly half-inch cubes, you’ll want to simmer them for about 15 to 20 minutes.
This is the sweet spot when both veggies turn fork-tender at the same time.
If you’re simmering potatoes and carrots in a soup or stew, this range still holds up well.
Just check them at the 15-minute mark with a fork and go from there.
2. Whole or Large Chunks Take Longer
If you leave your potatoes and carrots in larger chunks or whole, expect to simmer them for 25 to 30 minutes or even longer.
A whole medium potato can take up to 35 minutes to soften fully.
Same goes for thick carrot coins or large carrot sticks, which can take 20 to 25 minutes.
So when you’re figuring out how long to simmer potatoes and carrots, size really does matter.
3. Carrots Often Need a Head Start
Here’s a little secret most people miss: carrots are denser than potatoes, so they often need a few extra minutes.
If you’re simmering potatoes and carrots in the same pot, toss the carrots in first and let them cook for about 5 minutes before adding the potatoes.
That way, both finish at the same time and neither ends up overcooked.
This one tip alone can save your dish from turning into veggie mush.
What Affects How Long to Simmer Potatoes and Carrots
Several factors can change the simmer time for potatoes and carrots, so keep these in mind.
1. The Type of Potato You Use
Waxy potatoes like red potatoes hold their shape and take a bit longer to soften.
Starchy potatoes like Russets break down faster and may simmer in as little as 10 to 15 minutes.
So the type of potato you pick directly affects how long to simmer potatoes and carrots.
2. Fresh vs. Older Vegetables
Fresh potatoes and carrots from the farmers market tend to cook faster.
Older veggies that have been sitting in your fridge for weeks can take longer to soften.
Keep that in mind when you’re timing your simmer.
3. Altitude and Water Temperature
If you live at a high altitude, water boils at a lower temperature, which means your potatoes and carrots will need to simmer longer.
Always start with boiling water, then reduce to a gentle simmer rather than a rolling boil.
A gentle simmer cooks potatoes and carrots evenly without breaking them apart.
Tips for Perfectly Simmered Potatoes and Carrots
Want to simmer potatoes and carrots like a pro?
Here are a few simple tricks that make a big difference.
1. Cut Them the Same Size
Uniform pieces are the key to even cooking when you simmer potatoes and carrots.
Aim for consistent half-inch cubes or slices so everything finishes at the same time.
2. Salt the Water
Add a generous pinch of salt to your water before you simmer potatoes and carrots.
This seasons them from the inside out and enhances their natural flavor.
3. Start Timing Once the Water Returns to a Simmer
Don’t start your timer the moment you drop the veggies in.
Wait until the water comes back up to a gentle simmer, then begin counting.
That’s the most accurate way to know how long to simmer potatoes and carrots.
4. Test With a Fork, Not a Knife
A fork slides into a perfectly simmered potato or carrot with just a bit of resistance.
If it goes in with zero resistance, you’ve overcooked them.
So always test before you drain.
So, How Long to Simmer Potatoes and Carrots?
Potatoes and carrots usually need to simmer for about 15 to 20 minutes when cut into bite-sized cubes.
Larger chunks take longer, while starchy potatoes and smaller cuts cook faster.
Give carrots a short head start, salt your water, and always test with a fork before draining.
Now that you know exactly how long to simmer potatoes and carrots, you can whip up soups, stews, and side dishes with perfectly tender veggies every time.
Happy simmering.
