There’s something oddly comforting about a tray of roasted vegetables sizzling away in the oven, especially when the whole kitchen fills with that warm, buttery aroma. A few months ago, when I was knee-deep in trying new low-carb sides, I stumbled on a bag of turnips that looked… a little lonely. You know how sometimes an ingredient almost pleads with you to give it a moment to shine? That’s exactly how this recipe was born.
I remember slicing into those first turnips, trying to keep the knife steady while my brain yelled, “Don’t cut all the way through!” The little fan-like layers opened up so beautifully, and I swear I felt like some kind of veggie sculptor. As soon as the garlic butter seeped into all those tiny crevices, it hit me—this was going to be good.

When they came out of the oven? Oh my. The edges crisped just enough to feel indulgent, but the centers stayed tender and almost potato-like, without the carbs. I immediately grabbed a fork (and burned my tongue, classic me) because patience is not my strong suit.
Since then, these keto hasselback turnips have become a little ritual in my kitchen—holiday dinners, lazy Sundays, whenever I need something cozy but still healthy. Even friends who “don’t like turnips” ended up sneaking seconds. There’s just something playful, rustic, and deeply satisfying about them.
And hey—any excuse to drizzle extra garlic butter on something is fine by me.

How to Master the Perfect Keto Hasselback Turnips (My Secret Method)
Start by giving each turnip a good scrub—think of it like waking them up. Slice off the ends so they sit flat, then take a deep breath and begin those signature thin cuts. Go slow; even spacing makes them fan out beautifully in the oven.
Melt your butter with garlic and herbs until it smells like the start of a holiday dinner. Brush that liquid gold over the turnips, making sure it gets into all the little nooks. Halfway through roasting, they’ll begin to open up like little vegetable accordions—this is your cue to baste again and sprinkle parmesan if you’re feeling fancy. By the time they’re done, the edges will be crisp, the centers soft, and the whole tray irresistible.
Chef’s Notes and Tips For A Flawless Keto Hasselback Turnips
Try placing chopsticks on each side of the turnip as you slice—this simple trick keeps you from accidentally cutting all the way through. Also, don’t skip the mid-bake basting. It’s the secret to infusing that rich roasted flavor.
If your turnips are large, halve them first. Smaller ones cook more evenly and develop better caramelization, which is key for that classic hasselback look.
Get Creative! Easy Substitutions and Fun Variations
Swap butter for herb-infused olive oil for a dairy-free version. Add paprika or chili flakes for heat, or brush with pesto for a bright, herbal twist. A sprinkle of smoked salt at the end? Unreal.
Lighten It Up! Simple Swaps for a Healthier Keto Hasselback Turnips
Use ghee instead of butter, or skip dairy completely and rely on olive oil. For ultra-light versions, air-fry the turnips for crispiness with less fat. They’re naturally gluten-free and low-carb, so they’re already keto-friendly without much tweaking.

Are You Curious About Anything Else? Take a Look at the Most Frequently Asked Questions We Get About This Recipe:
1. Are turnips really keto-friendly, even when roasted?
Absolutely—turnips are one of the most keto-friendly root vegetables. Compared to potatoes, which are quite starchy, turnips stay low in carbs even when roasted. In fact, roasting them actually enhances their natural sweetness without increasing the carb count. This makes them ideal for anyone searching for a keto hasselback turnips recipe that feels indulgent but stays within macro goals.
Many keto cooks rely on roasted turnips in place of potatoes because they create that same soft-center, crispy-edge vibe. So yes, you can enjoy them without worrying about knocking yourself out of ketosis.
2. How do I get the perfect crisp on hasselback turnips?
The key is even slicing and proper fat distribution. When the thin layers open during roasting, you want the garlic butter (or olive oil) to coat every surface. Halfway-through basting is not optional if you want that picture-perfect crisp.
Also, high heat is your friend. A hot oven helps the edges brown beautifully while keeping the centers tender.
3. Do hasselback turnips taste like potatoes?
Surprisingly… yes, sort of! While they have a slightly peppery note, the texture when roasted is very similar to a tender baby potato. This is why many people use turnips in low-carb comfort dishes—they hit that same spot without the starch.
Once the butter, garlic, and herbs seep in, the flavor mellows dramatically, giving you that familiar cozy flavor profile.
4. Can I make keto hasselback turnips ahead of time?
You can. Prep the turnips up to the slicing stage and refrigerate them in water to prevent browning. When ready, dry them well, brush with butter, and roast as usual. They also reheat wonderfully in an air fryer or oven.
5. What’s the best size turnip for hasselback slicing?
Go for small-to-medium turnips. Large ones tend to be woodier and tougher. Smaller turnips roast more evenly, open up more beautifully, and give that classic hasselback fanned effect.
6. Why are my hasselback slices not opening properly?
Usually, the cuts weren’t quite deep enough. Try getting as close to the bottom as you can without slicing through (chopsticks help!). Turnips also open more as they roast, so basting helps encourage separation.
7. Can I use an air fryer for this keto hasselback turnips recipe?
Yes, and it works incredibly well. Air frying cuts the cook time, intensifies the crispiness, and still keeps the inside soft. Just reduce the baking time by about one-third and check frequently to avoid over-browning.
8. What should I serve with roasted keto hasselback turnips?
They pair beautifully with roasted chicken, steak, salmon, or even holiday turkey. Their subtle flavor makes them a flexible low-carb side dish, and they look impressive next to almost anything.
