Transitioning from a standard diet to a ketogenic diet often involves sacrificing certain foods, and potatoes are one such example.

A typical white potato contains over 30 grams of net carbs, which exceeds the daily allowance for a keto diet. As a result, many people seek alternatives to keto-friendly potatoes.

Are Sweet Potatoes Keto?

Sweet potatoes are not considered keto-friendly as they are relatively high in carbohydrates. A medium-sized sweet potato contains about 23 grams of net carbohydrates, which is more than the daily recommended amount for someone following a strict ketogenic diet.

When adhering to a ketogenic diet, it is recommended to steer clear of starchy vegetables such as sweet potatoes, regular potatoes, corn, and peas. It is advised to prioritize low-carb vegetables like leafy greens, cauliflower, broccoli, and zucchini instead.

Net carbs are calculated by subtracting the amount of fiber from the total carbohydrates. In the case of sweet potatoes, a medium-sized one contains about 4 grams of fiber, which means it has 24 grams of net carbs.

What Do They Taste Like?

Sweet potatoes have a mild, starchy, sweet taste when cooked. The flesh turns soft and slightly stringy when they are baked or cooked. However, if you choose to fry them, the exterior turns crisp and caramelized. The mild, sweet flavor of the vegetable makes it a popular ingredient in so many meals.

Can I Make Keto-Friendly Recipes Using Sweet Potatoes?

While sweet potatoes are not keto-friendly on their own, they can be used in moderation in some keto-friendly recipes. For example, you can try making a sweet potato crust for a keto quiche or use mashed sweet potatoes as a base for a low-carb shepherd’s pie. Just be sure to adjust your portion sizes and track your carb intake to stay within your daily limit.

Keto Substitutes For Sweet Potatoes

So after reading all this information, you will probably ask what sorts of vegetables you can eat instead of sweet potato on a keto diet. You will be happy to find out that various alternative options are open to you on your keto journey.

  • Butternut squash: It has a slightly sweet flavor and can be roasted, mashed, or pureed to replace sweet potatoes in various recipes.
  • Pumpkin: It is low in carbs and has a naturally sweet flavor. It can be roasted, mashed, or pureed to use as a substitute for sweet potatoes.
  • Carrots: They have a natural sweetness and can be roasted or mashed to mimic the texture and flavor of sweet potatoes.
  • Cauliflower – According to the USDA FoodData Central Database, 100 grams of cooked cauliflower contains 4.11 grams of carbohydrates and 2.3 grams of dietary fiber, giving it only 1.81 grams of net carbohydrates. So cauliflower is a very keto-friendly potato substitute! In fact, cauliflower is such a good substitute for potatoes that it can be cooked in so many ways like potatoes. You can make a puree. You can boil it, fry it and bake it in the oven.
  • Radishes: Roasted or boiled radishes can be used as a substitute for boiled or mashed potatoes. They have a similar texture and taste.
