Lets just get a couple of questions out of the way first.

Are Potatoes okay on Keto?

No. Potatoes are not a part of a Keto Diet. They have enough carbohydrates to kick you out of Ketosis almost immediately.

What are Some Keto Substitutes for Potatoes?

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….

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!

A celeriac root sitting on a counter so people know what they look like

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

How to prepare Celeriac:

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.

Served Low Carb Cottage Pie

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.

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.

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.

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.

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.

Low Carb Substitutes for Sweet Potatoes:

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.
