How long to cook potatoes and carrots in an Instant Pot depends on whether you’re cooking them together or separately, and whether they’re cubed, whole, or sliced.
The good news is that both vegetables cook relatively quickly under pressure.
In this post, we’ll break down exactly how long to cook potatoes and carrots in an Instant Pot so you get perfectly tender results every time.
We’ll also cover the best methods, common mistakes, and tips for getting consistent results.
Let’s dive in.
How Long to Cook Potatoes and Carrots in an Instant Pot
When you’re cooking potatoes and carrots together in an Instant Pot, the timing usually lands between 4 and 8 minutes at high pressure.
The exact time depends on how large your pieces are and whether you’re using whole or cut vegetables.
For cubed potatoes and sliced carrots, 4 to 5 minutes is usually enough.
For larger chunks, you’ll want to cook potatoes and carrots in the Instant Pot for about 6 to 8 minutes.
Whole potatoes and whole carrots take longer, often 10 to 12 minutes, because heat has to penetrate through the entire vegetable.
After the cooking time finishes, a quick release is fine for most recipes, though a natural release for 5 minutes can help prevent overcooking.
1. Cooking Cubed Potatoes and Carrots Together
If you’re making a stew, soup, or side dish, cubed potatoes and carrots are the most common cut.
Cut both into roughly 1-inch pieces so they cook at the same rate.
Add 1 cup of water or broth to the Instant Pot, place the vegetables in a steamer basket or directly in the liquid, and set the timer for 4 to 5 minutes on high pressure.
This is how long to cook potatoes and carrots in an Instant Pot when they’re diced small.
2. Cooking Larger Chunks or Halves
Larger pieces need more time.
If your potatoes are halved and carrots are cut into thick chunks, set the Instant Pot to 6 to 8 minutes on high pressure.
This is a good range when you want them fork-tender but not mushy.
Remember that potatoes and carrots cook at slightly different rates, but they’re close enough that they can share the same pot.
3. Cooking Whole Potatoes and Whole Carrots
Whole potatoes and whole carrots take the longest.
For whole baby potatoes and whole carrots, cook for 10 to 12 minutes on high pressure.
For large russet potatoes, you may need up to 15 minutes.
That said, most people prefer cutting them so they cook faster and more evenly.
Factors That Affect Cooking Time
Several things can change how long to cook potatoes and carrots in an Instant Pot.
Understanding these factors helps you adjust the time instead of guessing.
1. Size of the Pieces
The smaller the pieces, the faster they cook.
A 1-inch cube of potato cooks in about 4 minutes, while a whole potato can take 12 to 15 minutes.
Carrots behave the same way.
Sliced carrots cook in 3 to 4 minutes, while whole carrots need 10 minutes or more.
2. Type of Potato
Waxy potatoes like red or fingerling hold their shape well and cook a bit slower.
Starchy potatoes like russets break down faster and can turn mushy if overcooked.
If you’re cooking potatoes and carrots in an Instant Pot with russets, lean toward the shorter end of the time range.
3. Altitude and Liquid Amount
At higher altitudes, you may need to add 1 to 2 minutes to the cooking time.
Also, always use at least 1 cup of liquid to build pressure properly.
The liquid doesn’t change the cook time much, but it’s essential for the Instant Pot to work.
Best Tips for Perfect Potatoes and Carrots in the Instant Pot
Here are a few tips to get consistent results every time you cook potatoes and carrots in an Instant Pot.
1. Cut Them Evenly
Uniform pieces cook at the same rate.
If your pieces are uneven, some will be mushy while others stay firm.
Take an extra minute to cut them to similar sizes.
2. Use a Steamer Basket
A steamer basket keeps the vegetables out of the liquid, which prevents them from getting waterlogged.
It also makes it easier to remove them when they’re done.
3. Don’t Overcook
It’s easy to overcook potatoes and carrots in an Instant Pot because they cook fast.
Start with the shortest time and add more if needed.
You can always cook them longer, but you can’t undo mushy vegetables.
4. Quick Release vs. Natural Release
For firm vegetables, use a quick release right after the timer goes off.
For softer results, let the pressure release naturally for 5 minutes.
This is a small detail, but it makes a big difference in texture when you cook potatoes and carrots in an Instant Pot.
So, How Long to Cook Potatoes and Carrots in an Instant Pot?
How long to cook potatoes and carrots in an Instant Pot comes down to 4 to 8 minutes for most cut pieces.
Whole vegetables need 10 to 12 minutes.
Cubed pieces cook in 4 to 5 minutes, larger chunks take 6 to 8 minutes, and whole potatoes and carrots need 10 to 12 minutes or more.
Adjust based on size, potato type, and your preferred texture.
With these guidelines, you’ll get tender, flavorful potatoes and carrots every time.
