If you’re following a low-carb or keto lifestyle but still crave the crispy, salty satisfaction of French fries, this Keto French Fries Recipe will become your new favorite side dish.
Made with just 3 simple ingredients and absolutely no xanthan gum, these golden fries are flavorful, crisp, and guilt-free. The secret weapon here? Rutabaga — a low-carb root vegetable that crisps up beautifully without adding too many carbs.
1. Keto French Fries Recipe
Ingredients
- 2 large rutabagas, washed and patted dry
- 1 tablespoon olive oil
- 1/4 teaspoon rosemary (fresh or dried)
- 1 teaspoon salt (to taste)
- 1/4 teaspoon pepper (to taste)
Instructions
Start by prepping the rutabagas. Peel them using a vegetable peeler to remove the tough outer skin. Cut off the ends, then slice each rutabaga into 1/4-inch thick planks.
Stack the planks and cut them into thin strips resembling classic French fries. Aim for uniform sizes to ensure even cooking. Pat the cut fries dry with a paper towel to remove excess moisture, which helps achieve crispiness.
Toss the rutabaga strips in a large bowl with the olive oil, rosemary, salt, and pepper. Mix everything well to coat evenly. Now, you can choose your cooking method based on available equipment and desired texture.
Stovetop Frying Method
Heat a large skillet or frying pan over medium-high heat. Add enough additional olive oil or avocado oil to cover the bottom of the pan with a thin layer (about 2-3 tablespoons).
Once the oil shimmers, add the seasoned rutabaga fries in a single layer without overcrowding—work in batches if needed.
Fry for 8-10 minutes, stirring occasionally with a spatula to prevent sticking. Turn the fries every 2-3 minutes for even browning. They turn golden and crispy on the edges when done.
Drain on a paper towel-lined plate to absorb excess oil. Season with extra salt if desired, and serve immediately for the best texture.
Oven Baked Method
Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper or a silicone mat for easy cleanup.
Next, spread the seasoned rutabaga fries in a single layer on the sheet, ensuring they do not touch to promote crispiness.
Bake for 20-25 minutes, flipping halfway through with a spatula. Check for doneness when the edges crisp up and turn golden brown.
For extra crunch, switch to broil on high for the last 2 minutes, watching closely to avoid burning.
Remove from the oven and let them cool slightly before serving.
Air Fryer Method
Preheat your air fryer to 400°F (200°C) for 3-5 minutes.
Next, place the seasoned rutabaga fries in the air fryer basket in a single layer, avoiding overlap. If your basket fills up, cook in batches.
Air fry for 12-15 minutes, shaking the basket halfway through to ensure even cooking. The fries finish when they appear crispy and browned. Adjust time based on your air fryer’s model—some may need an extra 2-3 minutes.
Serve hot right from the basket.

2. Tips for Perfect Keto French Fries
Achieve restaurant-quality results by cutting the rutabagas as evenly as possible—thinner strips crisp faster, while thicker ones stay softer inside.
Soak the cut fries in cold water for 10-15 minutes before patting dry to remove starch and enhance crispiness.
You should use high-smoke-point oils like avocado oil for frying to avoid burning.
Monitor cooking times closely since rutabagas cook faster than potatoes.
Add seasonings after cooking if you prefer bolder flavors, as heat can mellow herbs like rosemary.
Experiment with batch sizes to fit your equipment, and always preheat for that initial sear.
3. Variations & Substitutions
Swap rutabagas for other low-carb veggies like zucchini, turnips, or jicama for a different twist—jicama offers a milder, sweeter profile.
Replace rosemary with garlic powder, paprika, or thyme for varied herb notes.
For a cheesy version, sprinkle grated Parmesan over the hot fries right after cooking.
If olive oil feels too mild, try coconut oil for a subtle tropical hint or ghee for buttery richness.
Adjust salt and pepper levels based on preference, or add a dash of cayenne for heat.
These swaps keep the recipe under 3 core ingredients while expanding options.
4. How to Store & Reheat Leftovers
Store cooled fries in an airtight container in the refrigerator for up to 3 days. Avoid stacking them to prevent sogginess—use parchment paper between layers if needed.
For longer storage, freeze them in a single layer on a baking sheet before transferring to a freezer bag; they last up to 2 months this way.
Reheat in the oven at 400°F (200°C) for 5-7 minutes to restore crispiness, or use the air fryer at 350°F (175°C) for 3-4 minutes. Skip the microwave, as it turns them mushy.
This Keto French Fries recipe is one of those staples that satisfies without sabotaging your macros. I love how accessible it is — no specialty ingredients, no gums or additives, and you can make it with tools you already have at home. Rutabaga has earned a permanent spot in my fridge just for this reason. So next time you’re craving fries, skip the carbs and give this recipe a try!
