FAQ’s:
Lets just get a couple of questions out of the way first.
No. Potatoes are not a part of a Keto Diet. They have enough carbohydrates to kick you out of Ketosis almost immediately.
There are nine great low carb substitutes for potatoes. Cauliflower is the most common. But kohlrabi, rutabaga, turnips,celeriac and jicama,etc can all be made into excellent alternatives with a few recipe additions.
On to the 9 great potato substitutes….

Cauliflower:
Let’s start with the elephant in the room.
I bet you already knew about this one. You might even be here because you HATE mashed cauliflower. It’s cool, I HAVE A TRICK up my sleeve that might make you fall in love with it. Keep reading and check out the recipe.
Cauliflower has been making serious waves in the Keto (and non-Keto) world because of its versatility and inflammation fighting properties! It’s even been shown to prevent cancer growth.
With its ability to act as a low-carb potato substitute, cauliflower can be mashed, roasted, and even fried for a delicious Keto side.

How to prepare a delightful Cauliflower Mash:
There are a ton of cauliflower side dish recipes out here in the big wide world of Keto recipes blogging. We even have one that contains bacon right here. (I might be biased because – bacon, and I developed that recipe).
But what I didn’t know when I originally started making Cauliflower mash is how much a few simple tweaks could take this low carb potato alternative from “meh” to “MMM mashed potatoes”.
This is a simple recipe that you can replicate no matter how much you want to make. It’s wayyyy to simple for it’s own formal post. I’ll use one small head of cauliflower as a guide:
Cauliflower Mashed Potato Substitute:
- Steam the Cauliflower.
- Cut into small pieces and put it in the blender.
- Add chicken bouillon in the place of salt (to taste- start with 1/4 or 1/2 teaspoon).
- Add 2 tablespoons of Mayonnaise to the blender (also to taste in place of heavy cream)
- Add butter (a tablespoon or two should do it)
Blend, taste and adjust. You can add herbs or spices like garlic or parsley if you want.
Just make sure you heat it back up on the stove or in the microwave to streaming before serving. The chicken bouillon powder in this low carb potato alternative recipe requires heat to ensure safety. Just heat it back to steaming and you should be good to go.
Is cauliflower mash exactly like mashed potatoes?
Nope. Is it “potato like” and damn tasty? Yep. Even the mashed potato hating teenager thinks it’s delicious.
So go ahead and give cauliflower a try. If you don’t like it, just keep reading to check out the other Keto potato substitute recipes I have for you!

Celery Root (Celeriac)
Yep, maybe you have passed this one by in the grocery store a thousand times without ever looking twice. It’s not Instagram beautiful or anything.
Celeriac looks like…well, a weird brown root ball with a lot of little curly roots coming out of the bottom and green sprouts coming out of the top. Not exactly gorgeous.
It looks like the part of the plant that usually gets turned into mulch…
BUT, this adaptable and highly nutritious root deserves more respect than we give it.
Yes, it does have a few more net carbs than some of the other low carb potato substitutes, but it doesn’t have a strong bite to cover up or boil out so it’s still a strong contender.
Nutritional info for 4 ounces of Celeriac:
- Amount Per 4 oz (113.4 g)
- Calories 48
- Total Fat 0.3 g
- Carbohydrates: 10 grams

Celeriac can be boiled and mashed like potatoes, or you can roast it with potato-like flavorings (garlic and herbs like rosemary are especially good).
If you’re feeling a bit more adventurous, grate the celeriac into a slaw for a pleasant crunch and unique tone. Or add to soups for a hearty and nutritious touch.

We use Celeriac as a topping on our Hearty Cottage pie instead of cauliflower. Isn’t it gorgeous? It’s delicious too. Get the recipe here.
Or, you can just bake it and enjoy as a side dish or chip like snack alternative…
Baked Celery Root:
- Wash and peel the root ball.
- Slice into fries or thin chips.
- Toss with olive oil, salt and pepper.(or whatever spices you like)
- Bake @ 425 for 35-40 minutes on an oiled baking sheet.
- Enjoy
Does Celery root taste like potato chips?
No. But it’s mild and picks up whatever spices you use. So, you can get the crunchy, salty satisfaction you are looking for.
Does Celery Root taste like Celery?
Celery root does taste a bit like celery when eaten raw, but it’s a little milder. It picks up the spices you use with it and takes on their flavors.
Rutabaga (Swede)
The humble Rutabaga is a great Keto-friendly potato substitute! Not only is it low in carbs and high in dietary fiber, but it also has a slighty sweet nutty bite that complements almost any savory meal. It’s perfect for making Rutabaga hash browns, fries, or even roasting up as a side! Plus, the fact that rutabaga is so versatile means that you can find a way to include it in almost any meal.

Kohlrabi
The Kohlrabi is a Keto dieter’s dream come true! This low-carb veg is the perfect substitute for potatoes if you’re looking to keep your carbs down. It has a unique flavor, similar to rutabaga (sometimes also called swede). You can use it as one of your side dishes or dice it up and eat it raw, or roast it in the oven, and serve it as a fantastic potato-like replacement.
So, don’t be afraid to try it. You don’t even have to peel it.

With its nutty flavor and crunchy texture, you’ll be sure to enjoy the deliciousness of potatoes without all the carbs!

Turnip
Ahh, the humble turnip. This is one I never thought I would willingly have in my kitchen lol. But, it turns out that Turnips are an amazing substitute for potatoes – especially if you’re on Keto.
Turnips have a sweet, earthiness – much like carrots or parsnips – that makes them a great substitute for potatoes in almost any dish. Plus, they’re high in vitamins A and C, so you can feel good about eating them too!
And did you know that turnips are sometimes referred to as ‘rutabagas’ or ‘swedes’? Different names for similar vegetables – there is much spirited debate about the correct names- but I’ll leave that out.

Red Radish
Wait, wait, don’t click away. I KNOW that most people hate the red radish but there is another Keto Diet Trick here that is GAME CHANGING! I promise.
Red Radish is not just some pungent, bright red root vegetable that looks like a cross between a tomato and an apple and tastes like the inside of a hobo’s shoe- it also has major benefits when it comes to nutrition.
Who would have thought it? But yes indeed, Red Radishes are Keto-friendly vegetables with a surprisingly low carb and calorie count.
Not to mention, it also contains Vitamin C, Vitamin B6, Calcium, Magnesium and Potassium – all of which are important for keeping our body healthy and energized while on the Keto diet.
Nutritional info for 4 ounces of Red Radishes :
- Amount Per 4 oz (113.4 g)
- Calories 18
- Total Fat 0.11 g
- Carbs: 3.86 grams
- Dietary fiber: 1.8 grams
- Net grams of Carbs : 8
How to Prepare the Red Radish:
No matter how you would like to prepare the red radish, to remove the “radish” bite you have to cook them in salted boiling water. About 35 minutes does the trick. The bright red radishes should lose their color to the water and emerge a lightish red/pink.
Only then will they be the most like potatoes for your coveted potato side dishes, soups and stews.
In fact, they are my favorite on this list! You can fry, bake or chop and serve these tender baby “alternative” faux potatoes any way you please.
But, we love this Keto “Faux” Potato Salad by the cup as do thousands of followers.
Or, if you are looking for something a bit heartier and refined, try them in this Keto Beef Bourguignon recipe. It’s divine.
Jicama
Jicama is the fantastic potato substitute when it comes to french fries. Not only is it a fraction of the calories and carbohydrates, but it also has a much higher fiber content than potatoes.
Plus, with its sweetish-sour taste and crunch that pairs perfectly with salt and spices. Furthermore, if you’re living a keto lifestyle, jicama is a great sub for french fries. They’re sure to hit the spot!
And, they make a decent “faux” Keto Green Apple Crumble too.

How to Prepare Jicama:
The Keto-Friendly French Fry Alternative!
Jicama, or Mexican yam bean, is a crunchy tuber with a delightful sweetness reminiscent of an apple. It’s the perfect keto-friendly alternative to conventional french fries.
Here’s how you can make your own jicama fries at home:
1. Start by prepping the jicama. Peel the tough outer skin, then slice into thick steak-cut fries.
2. Heat a skillet over medium heat and melt some butter in it.
3. Add the jicama slices to the pan and cook for about 4-5 minutes each side or until golden brown.
4. Sprinkle with salt and pepper, and any other seasonings of your choice.
5. Serve hot with sugar free ketchup or your favorite dipping sauce. Enjoy!
Jicama fries are a great way to give french fries a healthy upgrade while still enjoying their classic flavor and crunchy texture.
Jicama is also a tasty substitute for apples if you spice it right. This Keto Green Apple Crumble was made from Jicama.
Low Carb Substitutes for Sweet Potatoes:
Since we’re talking about low carb potato substitutes, lets throw sweet potatoes in the mix. The holidays won’t be the same without them!
I think Rutabaga is an excellent choice, all doctored up with butter, cinnamon, ground cloves and salt and pepper. But many of my readers suggest they don’t feel the same way.
So, this section will be dedicated to the ever enticing butternut squash. Cup for cup, it’s on the higher end of the net carbs spectrum.
It may be easier for someone on a strict Keto Diet to choose rutabaga when thinking about a sweet potato substitute.

Butternut Squash
Butternut is an excellent option for those who still want to enjoy the sweet flavor of a sweet potato. It’s loaded with vitamins and minerals, plus it has its own unique flavor that pairs very well with butter, spices and herbs. Plus, it’s a great source of fiber!
