Table of Contents

Potatoes are a staple in many diets around the world. However, for those following a low-carb or ketogenic diet, potatoes are often off the menu due to their high carbohydrate content.

But fear not, there are plenty of delicious and nutritious low-carb alternatives to potatoes that you can incorporate into your meals. This guide will introduce you to some of these alternatives and provide tips on how to prepare and cook them.

Why Look for Alternatives to Potatoes?

While potatoes are rich in vitamins and minerals, they are also high in carbohydrates. For individuals following a low-carb or ketogenic diet, or those with diabetes who need to manage their blood sugar levels, finding alternatives to high-carb foods like potatoes is essential.

Resistant Starch: Can Cooling Potatoes Make Them Healthier?

When discussing potatoes, especially in the context of a low-carb diet, it's essential to touch upon the concept of resistant starch.

Resistant starch is a type of starch that isn't fully broken down and absorbed in the small intestine. Instead, it travels to the large intestine where it acts similarly to soluble fiber, serving as a food source for beneficial gut bacteria. This fermentation process produces short-chain fatty acids, which have been linked to various health benefits, including improved gut health and reduced blood sugar spikes.

Interestingly, the way you prepare and consume potatoes can influence their resistant starch content. For instance, when you cook potatoes and then cool them down (as in a potato salad or reheated mashed potatoes), the cooling process transforms some of the digestible starches into resistant starch. This means that cold or reheated potatoes can have a lower glycemic impact than freshly cooked, hot potatoes.

However, it's important to note that while the presence of resistant starch can reduce the net carbs of the potato, it doesn't turn the potato into a low-carb food.

For those strictly following a low-carb or ketogenic diet, it's still advisable to limit potato consumption. But for individuals who are more flexible with their carb intake or are focusing on gut health, incorporating cooled potatoes occasionally might be a consideration.

12 Low-Carb Alternatives to Potatoes

1. Cauliflower

Cauliflower is the king of low-carb vegetables. It's a versatile vegetable that can be used as a substitute for potatoes in a variety of dishes. From cauliflower mash and roasted cauliflower, to cauliflower "potato" salad, this vegetable can mimic the texture and flavor of potatoes while keeping the carb count low.

When used to make cauliflower mash, steam the cauliflower rather than boiling it, and then let the steam escape before mashing or blending it with some butter and seasoning. The best texture is achieved in a blender or a food processor.

How to Prepare and Cook Low-Carb Potato Alternatives

Preparing and cooking low-carb potato alternatives can be as simple as chopping and roasting, or as complex as creating a low-carb "potato" salad with cauliflower. The key is to experiment with different cooking methods and seasonings to find what you enjoy the most.

Some potato alternatives like kohlrabi, rutabaga and parsley root take longer to soften so keep that in mind. If you plan on roasting kohlrabi, it may be best to par-boil before baking as otherwise it may end up too dry and tough.

Other potato alternatives such as zucchini and pumpkin, do not require long cooking to become soft. Finally, options like spaghetti squash tend to overcook and get mushy. This may not be necessarily bad if you plan on using it to make spaghetti squash mash.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

I just made your kohlrabi stew and gotta say it's my new favorite potato swap!

Thank you so much, I'm glad you liked it! 😊

This is perfect! Where do I find jicama and chayote in the UK I've never heard of those options. Thank you!

Hi Joeann, these may be hard to get in the UK. I got them from an online shop that's based in London but it was quite pricey. It's not very common in the UK so I mostly end up using zucchini.

LOVE all these ‘guides’ you’ve done!  Priceless!  Thank you…

Thank you Linda!

I just can't help you enough for all those incredible guides you've been sharing recently. Thank you so so much!!

Thank you so much Emma, more is coming 😊
