Hasselback Potatoes — Crispy & Buttery Recipe

Butter-slick ridges crackle under a fork and reveal a fluffy, steam-kissed interior—this is the joy of Hasselback potatoes. This classic Swedish technique turns ordinary potatoes into an elegant crowd-pleaser with thin, accordion-style slices that crisp on the edges and stay tender inside. After testing this method eight times on Yukon Gold, russets, and fingerlings, I settled on a simple approach that increases crispness without fuss.

This version balances oil and butter, uses a quick parboil to prevent torn slices, and relies on high heat to caramelize the exposed edges. I learned and refined these steps while cooking for large dinner parties, where consistent results matter. Read on for the full ingredient breakdown, exact timings, step-by-step photos, and pro tips that remove the guesswork and deliver restaurant-style potatoes at home. If you love crispy roast potatoes, you’ll find these an easy next step: crispy roast potatoes.

Why This Recipe Works

Thin, even slices increase surface area so more of the potato crisps while the center remains tender.
A brief parboil softens the interior so slices stay intact and cook evenly.
Butter adds flavor and browning; oil raises the smoke point for crispness.
High oven heat (220°C / 425°F) caramelizes the exposed ridges quickly without drying the whole potato.
Resting after roasting allows steam to settle so the slices separate cleanly for serving.

Ingredients Breakdown

Potatoes (900 g / 2 lb total; about 4 medium Yukon Gold or 6 small fingerlings): Yukon Golds are ideal — waxy enough to hold shape but fluffy inside. Russets give a drier, fluffier center and a crisper finish.
Butter (60 g / 4 tbsp), melted: Adds rich browning and flavor. For a dairy-free version, use melted refined coconut oil or vegan butter (see substitutions).
Olive oil (30 ml / 2 tbsp): Raises the smoke point and keeps slices crisp. If using extra-virgin, pick a mild one to avoid a strong fruity note.
Garlic (3 cloves), minced: Pressed garlic melts into the crevices for savory pockets of flavor.
Fresh rosemary or thyme (2 tbsp chopped): Herbs infuse the butter and oil; rosemary gives a piney note, thyme is subtler.
Kosher salt (to taste) — Diamond Crystal recommended: If you use Morton’s, start with half the amount because Morton’s is denser.
Black pepper (freshly ground): Adds a bright counterpoint to the fat.
Optional: grated Parmesan (30 g / 1/3 cup) or a pinch of smoked paprika for finishing.

Substitutions with impact warnings:

Swap Yukon Gold for russet for a fluffier center but expect slightly more splitting during slicing.
Replace butter with vegan butter: flavor changes slightly and browning may be less pronounced.
Skip garlic to suit sensitive palates, but you’ll lose a key savory note.

Essential Equipment

Sharp chef’s knife and a small paring knife for trimming ends.
1 large baking sheet lined with parchment or a silicone mat — important to prevent sticking and to collect drippings.
Kitchen towels or paper towels for drying potatoes.
Two wooden chopsticks or the handles of wooden spoons to use as slicing guides so you don’t cut through the base.
Large pot for parboiling.
Optional: a mandoline can create perfectly even slices but be careful — thin slices cut easily through the base. For a safe home substitute, use the chopstick method.

Step-by-Step Instructions

Prep Time: 15 minutes — Cook Time: 45 minutes — Inactive Time: None — Total Time: 1 hour — Servings: 4

Step 1: Choose and prep the potatoes

Wash and scrub 900 g (2 lb) medium Yukon Gold potatoes and pat dry. Trim a thin slice from the bottom so each potato sits flat and won’t roll while slicing. This takes about 5 minutes.

Step 2: Parboil the potatoes

Place potatoes in a pot, cover with cold water, add 1 tsp kosher salt, and bring to a gentle boil. Parboil for 8 minutes — the potatoes should be just fork-tender at the surface but still firm in the core. Drain and let cool for 5 minutes; this softens the center and reduces tearing when you slice.

Step 3: Slice into Hasselback form

Place two chopsticks on either side of a potato and slice vertically about 2–3 mm (1/16–1/8 in) apart, cutting down until the blade rests on the chopsticks. Leave the base intact. This step takes 6–8 minutes for the batch. Keep the slices even — uneven slices cook unevenly.

Step 4: Season and oil between slices

Mix 60 g (4 tbsp) melted butter, 30 ml (2 tbsp) olive oil, 3 minced garlic cloves, 2 tbsp chopped rosemary, 1 tsp kosher salt (adjust if using Morton’s), and ½ tsp freshly ground black pepper. Brush or spoon the mixture over the potatoes, letting some drip into the crevices. This takes 4 minutes.

Step 5: Roast at high heat

Arrange potatoes on the baking sheet and roast at 220°C (425°F) for 35–45 minutes, turning once at 20 minutes and basting with any pan juices. Roast until the ridges are deep golden and crisp and the interior registers about 98°C (208°F) when tested with a probe. Expect 35–45 minutes depending on potato size.

Step 6: Finish and rest

If using Parmesan, sprinkle 30 g (1/3 cup) over potatoes in the last 5 minutes of roasting for a cheesy crust. Let rest 5 minutes before serving so steam subsides and slices fan out neatly. Serve warm. Total active hands-on time: about 25 minutes.

Expert Tips & Pro Techniques

Use the chopstick trick to prevent slicing through the base — it guarantees intact but flexible slices.
Common mistake: slicing unevenly or too thinly. Avoid razor-thin cuts that split off; aim for 2–3 mm (1/16–1/8 in).
Don’t skip parboiling — it preserves the potato shape and speeds roasting. Parboil for exactly 8 minutes; overboiling makes slices fall apart.
Make-ahead: Parboil, slice, and store uncooked in an airtight container with a damp paper towel in the fridge up to 24 hours. Brush with the flavored butter just before roasting.
Professional technique adapted for home: baste once mid-roast with clarified butter for extra sheen without burning.
To elevate flavor for a dinner party, tuck thin herb butter pats between a few slices just before serving.
For even browning, rotate the pan halfway through and tilt it to pool oil on the hotter edge.

Storage & Reheating

Refrigerator: Store cooled leftovers in an airtight container for up to 3 days. Refrain from stacking slices tightly — keep a single layer if possible to protect crisp edges.
Freezer: You can freeze cooked Hasselbacks, but they lose some crispness. Flash-freeze on a sheet for 1 hour, then transfer to a freezer bag for up to 2 months. Thaw in the fridge overnight.
Reheating: Reheat in a 175°C (350°F) oven for 10–12 minutes to revive crispness. For best edge crisp, finish at 220°C (425°F) for 2–3 minutes. Avoid microwaving — it makes the ridges soggy.

Variations & Substitutions

Garlic-Parmesan: After step 4, sprinkle 30 g (1/3 cup) grated Parmesan and roast as directed. Keeps times the same.
Dairy-free: Replace butter with 60 g (4 tbsp) melted refined coconut oil. Flavor will be milder and browning somewhat reduced; roast an extra 5 minutes if needed.
Herbed Lemon: Add 1 tsp lemon zest and 1 tbsp chopped parsley after roasting for fresh brightness. No other changes.
Spiced-Smoked: Swap paprika and cumin (1 tsp smoked paprika + ½ tsp ground cumin) into the butter mix. Flavor shifts to a smokier profile; keep bake time the same.
Twice-baked mash finish: Roast until nearly done, scoop a bit of center, mix with butter and sour cream, return to oven for 5 minutes. If you like twice-baked techniques, see this easy twice-baked potatoes adaptation: easy twice-baked potatoes.

Serving Suggestions & Pairings

Serve alongside roasted chicken or a simple pan-seared steak for a classic main course.
Green vegetable pairing: sautéed green beans or a lemon-dressed arugula salad cuts the richness.
Sauce ideas: a garlic-parsley gremolata or a mustard cream sauce complements the crispy edges.
For a casual plate, top with sour cream and chives and pair with our creamy mashed potatoes for variety: creamy make-ahead mashed potatoes.

Frequently Asked Questions

Q: Why did my potatoes fall apart when I sliced them?
A: Most likely they were over-parboiled. Parboil for about 8 minutes so the potatoes are softened at the surface but still firm inside. Also use the chopstick method to prevent cutting through the base.

Q: Can I make this without eggs?
A: Yes — this recipe contains no eggs. The texture relies on parboiling and roasting, not egg binding.

Q: Can I double this recipe for a crowd?
A: Yes. Roast on two sheet pans and rotate them halfway through. Avoid crowding the pans, which reduces airflow and prevents crisping.

Q: Can I prepare these the night before?
A: Yes. Parboil and slice the potatoes, then cover and refrigerate up to 24 hours. Brush with the butter-oil mixture and roast just before serving.

Q: How long do leftovers keep in the fridge?
A: Store in an airtight container for up to 3 days. Reheat in the oven to restore crispness.

Q: What potato type gives the best result?
A: Yukon Golds are a great all-around choice: they brown nicely and hold shape. Russets yield a fluffier interior and crisp exterior but can split more during slicing.

Q: Can I use a mandoline to slice them?
A: You can, but a mandoline may cut through the base unless you adjust the stop. For safety and control, the chopstick method is more reliable for home cooks.
