Cooking potatoes and carrots in a slow cooker takes about 3 to 4 hours on high or 6 to 8 hours on low, depending on how you cut them and what else is in the pot.
If you’ve been wondering how long to cook potatoes and carrots in a slow cooker, the short answer is simple, but the details are what make them come out perfectly tender every time.
Both vegetables hold up beautifully to slow cooking, and once you know the timing, you can toss them in and forget about them.
In this post, we’ll break down exactly how long to cook potatoes and carrots in a slow cooker, the best ways to prep them, and how to avoid mushy results.
Let’s get right into it.
How Long to Cook Potatoes and Carrots in a Slow Cooker
How long to cook potatoes and carrots in a slow cooker really comes down to three things: the size of your cuts, your heat setting, and whether you’re cooking them alone or with meat.
Here’s a quick breakdown so you can plan your meal with confidence.
1. On High Setting
When cooking potatoes and carrots in a slow cooker on high, plan for about 3 to 4 hours.
Cut your potatoes and carrots into roughly 1 to 2 inch chunks so they cook evenly.
Smaller pieces will be done closer to the 3 hour mark, while larger chunks may need the full 4 hours.
Always check tenderness with a fork before serving, because every slow cooker runs a little differently.
2. On Low Setting
If you want to cook potatoes and carrots in a slow cooker on low, give them 6 to 8 hours.
This is the setting I recommend when you’re heading to work and want dinner ready when you walk in.
Low and slow gives the carrots a lovely sweetness and lets the potatoes soak up whatever broth or seasoning you’ve added.
Just keep the lid on and resist the urge to peek, since every time you lift it, you add cooking time.
3. When Cooked With Meat
Cooking potatoes and carrots in a slow cooker with a roast, chicken, or stew meat changes the timing slightly.
Place the carrots on the bottom, then the meat, then the potatoes on top.
Carrots take the longest, so they need that bottom spot closest to the heat.
With meat in the pot, expect potatoes and carrots to need the full 6 to 8 hours on low or 3 to 4 hours on high.
How to Prep Potatoes and Carrots for the Slow Cooker
Knowing how long to cook potatoes and carrots in a slow cooker also means prepping them the right way.
Good prep is half the battle, and it keeps your veggies from turning to mush.
1. Cut Them Into Even Chunks
Cut potatoes and carrots into similar sized pieces, about 1 to 2 inches.
Even chunks mean everything finishes cooking at the same time.
If your pieces are all different sizes, some will turn to mush while others stay hard.
2. Keep the Skin On
You don’t have to peel your potatoes or carrots for the slow cooker.
The skin helps them hold their shape during those long hours of cooking.
Just scrub them well under running water and cut off any bruised or soft spots.
3. Don’t Overfill the Pot
Fill your slow cooker no more than two thirds of the way full.
Overfilling traps steam and slows down cooking, which throws off your timing.
Leave some headroom so the heat can circulate around the potatoes and carrots.
Tips for Perfect Slow Cooker Potatoes and Carrots
Once you know how long to cook potatoes and carrots in a slow cooker, these tips will take your results from good to great.
1. Add Liquid, but Not Too Much
Add about half a cup to one cup of broth or water to the pot.
Potatoes and carrots release their own moisture as they cook, so you don’t need to drown them.
Too much liquid turns them soggy, while too little lets them dry out and stick.
2. Season Early
Season your potatoes and carrots before they start cooking.
Salt, pepper, garlic powder, and fresh herbs like thyme or rosemary all work wonderfully.
Seasoning early gives the flavors time to soak deep into every bite.
3. Choose Waxy Potatoes
For slow cooking, reach for waxy potatoes like red or Yukon gold.
They hold their shape far better than starchy russets, which tend to fall apart.
If you only have russets on hand, cut them larger and check them earlier.
So, How Long to Cook Potatoes and Carrots in a Slow Cooker?
Potatoes and carrots take about 3 to 4 hours on high or 6 to 8 hours on low in a slow cooker.
Prep them into even 1 to 2 inch chunks, keep the skin on, add a little liquid, and season early for the best results.
Remember that carrots go on the bottom, potatoes on top, and always check for fork tenderness before serving.
Now that you know how long to cook potatoes and carrots in a slow cooker, you can enjoy tender, flavorful veggies with almost zero effort.
