What is a Rutabaga?!

That 👆 is a rutabaga!

It’s a cruciferous root vegetable – in contrast, a potato is a non-cruciferous root vegetable. Rutabagas are a staple in Northern European cuisine and are also referred to as a “Swedish turnip.”

If you purchase them at the grocery store, you’ll find that they are covered in a waxy coating, which helps prevent them from drying out during storage. Before you consume a rutabaga, you will want to remove the waxy coating. In this recipe, you will also remove the peel.

Are Rutabagas Low in Carbs?

They’re not the lowest-carb vegetable out there, but compared to traditional fries made with potatoes, they’re significantly lower in carbs:

  • 100g rutabaga = 6.3g net carbs
  • 100g potato = 18.8g net carbs

As you can see, an equal amount of rutabaga is 1/3 the net carbs of a potato.

How to Make Keto French Fries {Quick Overview}

This is just a quick overview of some of the steps involved in making the low carb fries. For the recipe in detail, including exact measurements used at each step, scroll to the recipe card at the end of the post.


four steps to making keto fries with rutabaga

Peel rutabaga. (Photo 1)

Cut into fry-sized strips and season per recipe instructions. (Photo 2)

Place seasoned fries onto non-stick baking sheets (I used two medium sheets) in a single layer. (Photo 3)

NOTE: I lined my sheets with parchment paper for better photos, but this isn’t necessary.

Bake for 18-30 minutes, tossing every five minutes, until the fries have started to brown. (Photo 4)

NOTE: Photos 3 and 4 show only half of the fries this recipe makes. As noted, to bake all of the fries, you will need to use two baking sheets.

What Goes with Keto French Fries?

Is Ketchup Keto-Friendly?

You probably noticed the ketchup in the photo above.

If you buy (or make) ketchup with no added sugar, then ketchup is keto-friendly.

You can’t use a lot of it (1 tbsp is 1-2g net carbs), but a little goes a long way in providing that traditional fries-and-ketchup experience!

Here are a few of the no added sugar ketchup brands I’ve tried and liked:

Can I Eat French Fries When Eating the Keto Diet?

No, you need to avoid eating any French fries made from potatoes while eating the keto diet. However, these keto fries substitute are a worthy replacement and can be eaten in moderation.

Also, you must avoid the temptation of eating French fries during any keto fast food experiences. I have made these useful food ordering guides for when you eat Keto McDonalds, Burger King Keto, Low Carb Chick-fil-A and Wendys Keto.

What is a Good Substitute for French Fries on the Keto Diet?

You can eat French fries on the keto diet when you substitute potatoes with a rutabaga. A rutabaga has fewer net carbs than potatoes and can be eaten on the keto diet. 

When eaten within the macro guidelines of the keto diet and baked correctly, a rutabaga successfully replaces potatoes when you want to eat French fries. 

Are Rutabaga Fries Very Low in Carbs?

A small portion of these fries contains 6g net carbs. You won’t be able to eat these low carb fries with reckless abandon, but you will be able to enjoy enough to be satisfied!

    I never purchased a rutabaga before but this recipe for Keto Fries looked too good to ignore. Thank you so much for these tasty fries! I made them last night to serve with dinner and they were delicious. My kids and husband gave these fries high ratings and I will certainly make them again.

    • Hi Kimberly, Yes! You can make them in the air fryer. I haven’t found them to be any crispier when made in the air fryer, but it’s a good alternative to the oven.
