Who says you have to give up crispy, golden French fries on a keto diet? Definitely not here. These Crispy Keto French Fries give you that classic fry experience—crunchy on the outside, tender on the inside—without the carb overload.
Instead of potatoes, this recipe uses rutabaga, a low-carb root vegetable with a mild, slightly sweet flavor that crisps up beautifully in the oven or air fryer. With only 6g net carbs per serving, these fries are a smart, satisfying alternative to traditional fries that can contain 30–40g net carbs per serving.
Perfect as a side dish, snack, or even a meal add-on, these fries fit seamlessly into a keto or low-carb lifestyle.
🥔 Why These Keto Fries Work So Well
Low-Carb Swap That Actually Tastes Good
Rutabaga mimics the texture of potatoes far better than many keto substitutes, making it ideal for fries.
Crispy Without Frying
Baking (or air-frying) gives you that golden crunch—no deep fryer required.

🛒 Ingredients (Makes 8 Servings)
Basic Ingredients
- 1 large rutabaga, peeled and cut into ¼-inch thick fries
- ¼ cup avocado oil (olive oil also works)
- 1 tsp sea salt
- ¼ tsp black pepper
Optional Flavor Boosters
Use one or mix and match:
- ½ tsp garlic powder
- ½ tsp smoked paprika
- ½ tsp Italian seasoning
- ¼ cup grated Parmesan cheese (add during the last 5 minutes of baking)
🔥 Step-by-Step Instructions
1️⃣ Preheat & Prepare
Preheat your oven to 400°F (204°C).
Line a large baking sheet with parchment paper. For extra crispiness, place a cooling rack on top of the baking sheet—this allows hot air to circulate around the fries.
Peel the rutabaga and slice it into ¼-inch thick rounds, then cut each round into fries.
2️⃣ Season the Fries
Place the cut rutabaga into a large mixing bowl.
Drizzle with avocado oil, then add salt, black pepper, and any optional seasonings you’re using.
Toss thoroughly until every fry is evenly coated—this step is key for even crisping.
3️⃣ Arrange for Maximum Crisp
Spread the fries in a single layer on the rack or directly on the baking sheet.
Make sure they’re not overlapping—crowding causes steaming, not crisping.
4️⃣ Bake Until Golden
Bake for 35–45 minutes, flipping the fries halfway through.
They’re ready when:
- The edges are golden brown
- The outside is crisp
- The inside is fork-tender
For extra crunch, broil for the last 2–3 minutes while keeping a close eye on them.
5️⃣ Serve & Enjoy
Let the fries cool for 2–3 minutes before serving—they crisp up even more as they rest.
Serve with keto-friendly dips like:
- Sugar-free ketchup
- Garlic aioli
- Homemade ranch
- Warm cheese sauce
💡 Pro Tips for Best Results
- Uniform cuts matter – Even sizing ensures even cooking
- Use enough oil – Rutabaga needs fat to crisp properly
- Don’t rush the bake – Low-and-slow crisping works best
🧊 Storage & Reheating
- Store leftovers in an airtight container for up to 3 days
- Reheat in the oven or air fryer at 375°F for 5–7 minutes
- Avoid microwaving—it softens the fries
