Why These Potatoes Are Irresistible
These Hasselback-style potatoes aren’t just visually stunning — they’re a texture lover’s dream. The high-heat roasting creates potato-chip-like edges while locking in a tender, fluffy center. Using butter instead of oil gives them a rich, nutty flavor as it browns, while rosemary sprigs and smashed garlic cloves infuse the potatoes with aromatic depth. Finished with a sprinkle of flaky sea salt, every bite offers the perfect balance of crispiness, savoriness, and herbal freshness.
Ingredients You’ll Need
• Yukon Gold Potatoes: Naturally creamy with a buttery flavor, ideal for roasting.
• Salted Butter: Adds richness and helps create crisp edges.
• Fresh Rosemary: Provides an earthy, pine-like aroma and taste.
• Garlic Cloves: Infuses subtle warmth without overpowering.
• Kosher Salt: Enhances the potatoes’ natural flavor.
• Black Pepper: Adds a gentle kick to balance the richness.
• Flaky Sea Salt: A finishing touch for extra crunch and flavor.
Ingredient Swaps & Variations
• Potatoes: Try baby red potatoes or fingerlings for a slightly different texture.
• Butter: Use ghee for a nuttier note or olive oil for a lighter option.
• Herbs: Swap rosemary with thyme or sage for a fresh twist.
• Garlic: Replace with roasted shallots for a sweeter flavor profile.
Step-by-Step Cooking Method
- Preheat the oven to 450°F (230°C) for optimal crisping.
- Slice each potato thinly in the Hasselback style, stopping about 1/8 inch from the base. Use wooden spoons on either side to prevent cutting through.
- Place potatoes in a large roasting pan and toss with melted butter, chopped rosemary, kosher salt, and black pepper.
- Add smashed garlic cloves and whole rosemary sprigs to the pan for gentle infusion. Arrange potatoes cut-side down for the first roast.
- Roast for 20–25 minutes, then flip potatoes and spoon over the buttery pan juices so they seep between the slices.
- Return to the oven for another 20–25 minutes until golden brown and crisp.
- Serve warm, drizzling with any remaining butter from the pan and sprinkling with fried rosemary and flaky sea salt.

Pro Tips for Perfect Results
• Use small, even-sized potatoes for consistent cooking.
• Position slices thin and uniform for maximum crispiness.
• Don’t skip flipping halfway — it ensures every slice gets buttery crisp edges.
• Serve immediately to enjoy the full crunch factor.
Serving & Pairing Suggestions
These potatoes pair beautifully with roasted chicken, grilled steak, or baked salmon. They also shine alongside festive mains like beef tenderloin or holiday turkey. For a vegetarian plate, pair with a vibrant salad and roasted vegetables.
Make-Ahead & Storage Notes
You can prep and slice the potatoes a few hours ahead; store them in cold water to prevent browning. Leftovers can be reheated in a hot oven to revive crispiness — avoid microwaving, which softens the edges.

FAQs
1. Can I make Crispy Rosemary Butter Roasted Potatoes ahead of time?
Yes. You can slice the potatoes and prepare the butter-herb mixture earlier in the day. Keep the sliced potatoes in cold water to prevent browning, then drain and dry before roasting. For best texture, roast them right before serving.
2. What’s the best way to reheat leftovers?
Reheat in a 400°F (200°C) oven for 10–15 minutes to restore crispiness. Avoid microwaving, as it will soften the edges and reduce the crunch factor.
3. Can I use dried rosemary instead of fresh?
You can, but fresh rosemary offers a more vibrant and aromatic flavor. If using dried rosemary, reduce the amount to about one-third of the fresh quantity to avoid overpowering the potatoes.
4. Are these potatoes gluten-free?
Yes. This recipe contains no gluten ingredients, making it naturally gluten-free. Just confirm that your butter and seasonings are certified gluten-free if needed.
