Potatoes and carrots usually need about 15 to 20 minutes of simmering when cut into bite-sized chunks.
If you’re wondering how long to simmer potatoes and carrots, the answer depends on a few things like the size of your cuts, the type of potato, and whether you’re going for tender or fork-soft.
In this post, we’ll walk through exactly how long to simmer potatoes and carrots, how to tell when they’re perfectly done, and tips to keep them from turning to mush.
How Long to Simmer Potatoes and Carrots?
The short answer is simple, but the details matter if you want great results every time.
Simmering potatoes and carrots together generally takes around 15 to 20 minutes once the water is at a gentle boil.
That said, the exact time for how long to simmer potatoes and carrots really comes down to how you’ve prepped them.
Larger chunks will need closer to 25 minutes, while smaller diced pieces might be ready in just 10 to 12 minutes.
So let’s break it down by a few key factors.
1. Size of the Cuts Matters Most
The single biggest factor in how long to simmer potatoes and carrots is how big your pieces are.
If you cut both into uniform one-inch cubes, they’ll typically be tender in about 15 to 18 minutes.
Smaller half-inch dice can cook in as little as 10 minutes, so keep an eye on them.
The goal is even sizing so the potatoes and carrots finish at the same time.
2. Carrots Usually Take Slightly Longer
Carrots are denser than potatoes, so they often need a couple extra minutes.
That’s why many cooks add carrots first and potatoes a few minutes later.
If you’re simmering them together from the start, cut the carrots a touch smaller than the potatoes.
This little trick keeps your how long to simmer potatoes and carrots timing balanced.
3. Type of Potato Changes the Time
Waxy potatoes like red or fingerling hold their shape and may take closer to 20 minutes.
Starchy potatoes like russets break down faster and can soften in about 12 to 15 minutes.
If you want clean, firm cubes for a salad, go waxy and lean toward the shorter side.
For mashed or soups, starchy potatoes are perfect even if they get a bit softer.
How to Tell When Potatoes and Carrots Are Done Simmering
Knowing when to stop is just as important as knowing how long to simmer potatoes and carrots.
The best test is the fork test, and it never lies.
Here’s how to check them properly and avoid overcooking.
1. The Fork or Knife Test
Pierce a potato chunk with a fork or paring knife.
If it slides in easily with just a little resistance, it’s done.
If it crumbles or falls apart, you’ve gone a bit too far.
Carrots should feel tender but still hold their shape when pierced.
2. Taste One Piece
The most reliable way to check how long to simmer potatoes and carrots is simply to taste them.
Fish out a piece of each and let it cool for a second.
You want a texture that’s soft but not mushy, with a gentle bite left in the carrot.
This is the moment to pull them off the heat.
3. Watch for Color and Texture Changes
Potatoes turn slightly translucent at the edges when they’re close to done.
Carrots deepen in color and lose that raw, chalky look.
These visual cues pair perfectly with the fork test.
Together, they help you nail the timing every single time.
Tips for Perfectly Simmered Potatoes and Carrots
A few small habits make a big difference in how long to simmer potatoes and carrots and how good they turn out.
Start with cold water and add a generous pinch of salt.

Add a splash of acid like lemon juice or vinegar if you want carrots to stay firm.
And always set a timer for the lower end of your estimate so you can check early.

Once they’re done, drain them right away to stop the cooking process.
If you’re serving them later, shock them in ice water to lock in the texture.
