Ingredients You'll Need
Getting this recipe right is all about using straightforward, quality ingredients that transform into something magical. Each plays a unique role—potatoes provide a sturdy, fluffy base; butter and olive oil bring crispness and richness; garlic amps up flavor; and Parmesan adds that irresistible salty crunch. The creamy garlic sauce ingredients are simple but essential, perfectly balancing the potatoes with a tangy and smooth finish.
- 3 medium russet or Yukon Gold potatoes: Choose potatoes similar in size to ensure even baking and a uniform look.
- 2 tablespoons melted butter (28 g): This rich, golden butter brings deep flavor and helps crisp the edges.
- 2 tablespoons olive oil (30 ml): Olive oil helps distribute the butter evenly and keeps slices beautifully crisp.
- Salt and black pepper, to taste: Essential to enhance natural flavors and season each nook and cranny.
- 1 garlic clove, finely grated: Fresh garlic infuses the potatoes with a wonderful aroma and mouthwatering flavor.
- ¼ cup grated Parmesan cheese (50 g): Adds a salty, crunchy finish when sprinkled near the end of baking.
- Fresh herbs or greens (e.g., parsley, chives): A bright garnish giving freshness and color.
- ¼ cup thick Greek yogurt or sour cream (50 g): Forms the creamy base of the garlic sauce with a tangy kick.
- ¼ cup mayonnaise (50 g): Blends smoothly with yogurt for richness and texture.
- 1 garlic clove, finely grated: A little extra garlic for that bold, creamy garlic sauce flavor.
How to Make Crispy Hasselback Potatoes with Creamy Garlic Sauce Recipe
Step 1: Preheat and Prepare Your Potatoes
Start by setting your oven to 400°F (200°C) to get it nice and hot for that perfect crisp on your potatoes. Wash your potatoes thoroughly to remove any dirt because their skin is going to play a starring role once baked. The fun part is slicing: carefully cut thin slices about ⅛ inch apart, stopping just before slicing all the way through—that keeps each potato intact while letting the buttery garlic mix seep inside. Pro tip: placing chopsticks or wooden spoons along each side helps protect and guide your cuts perfectly.
Step 2: Mix and Brush the Garlic Butter
In a small bowl, whisk together melted butter, olive oil, freshly grated garlic, salt, and pepper. This simple mixture is the magic that transforms plain potatoes into a golden, crispy sensation. Use a brush to generously coat each potato, making sure the butter dips into every slit. This step ensures that crispy edges and deep flavor develop with each bake.
Step 3: Bake Until Crispy and Golden
Place the butter-brushed potatoes on a baking tray and pop them into your preheated oven. Bake for 45 to 50 minutes, occasionally basting with the flavorful pan drippings. As they roast, watch the edges fan out and get gloriously crunchy and browned. Tilt the pan to collect drippings and pour back over them to keep the potatoes moist and flavorful throughout.
Step 4: Prepare the Creamy Garlic Sauce
While the potatoes are baking, mix up the sauce that will take this dish to the next level. Combine thick Greek yogurt (or sour cream), mayonnaise, and a touch of grated garlic in a small bowl. Stir until smooth and creamy. This cool, tangy sauce will contrast wonderfully against the warm, crispy potatoes.
Step 5: Finish and Serve
Once your potatoes are baked just right, sprinkle grated Parmesan generously over the top, letting it melt into the hot crispy edges. Add chopped fresh herbs for brightness and an inviting color pop. Serve these beauties hot alongside the creamy garlic sauce, and watch them disappear fast!

Garnishes
A sprinkle of fresh parsley or chives adds the perfect fresh lift to these rich, crispy potatoes. Not only do herbs enhance visual appeal, but they also add a lovely subtle flavor that balances the richness of the butter and cheese elegantly.
Side Dishes
These potatoes are incredibly versatile. They pair beautifully with roasted meats like chicken or beef, grilled veggies, or even a crisp green salad to round out a lighter meal. They also make a delightful addition to any holiday spread or casual weekend dinner.
Creative Ways to Present
If you’re serving several guests, arrange your crispy hasselback potatoes in a large platter lined with fresh herbs and extra Parmesan. Let guests dip freely into little bowls of the creamy garlic sauce. For a fun twist, try topping a few with crumbled bacon, a dollop of sour cream, or even smoked paprika for added color and flavor dimensions.
Make Ahead and Storage
Storing Leftovers
Allow leftover potatoes to cool completely before storing to prevent sogginess. Place them in an airtight container and refrigerate for up to three days. Store the creamy garlic sauce separately to keep it fresh and avoid mixing flavors prematurely.
Freezing
Freezing is not recommended for the potatoes as it changes their texture and causes loss of that delightful crispiness. The sauce also doesn’t freeze well and can separate upon thawing, so it’s best enjoyed fresh.
Reheating
The best way to bring leftover Crispy Hasselback Potatoes with Creamy Garlic Sauce Recipe back to life is in the oven at 375°F until warm and crispy again. An air fryer works wonders too, quickly reviving that crunch. Avoid microwaving if you want to maintain the crispy texture.
FAQs
Can I use a different type of potato?
Yes! Yukon Gold and russet potatoes are ideal for this recipe because they balance fluffiness with crispiness, but feel free to experiment with red potatoes or smaller varieties. Just remember cooking times might change slightly depending on the potato type and size.
How do I keep from slicing all the way through the potato?
A really handy trick is to place chopsticks or wooden spoons on each side of the potato before slicing. They act as a natural barrier so your knife stops at the right depth every time, giving you those classic Hasselback fans without cutting through.
Can I make these ahead of time?
Absolutely! You can slice and brush the potatoes with the garlic butter mixture a few hours before baking and keep them covered in the fridge. Bake them just before serving to keep the edges crisp and fresh.
Why aren’t my potatoes getting crispy?
To ensure crispy edges, use a hot oven and baste the potatoes a couple of times while baking. If they’re still soft, finishing them under the broiler for a few minutes will help achieve that perfect golden crunch. Also, don’t overcrowd your baking tray, so heat circulates evenly.
Do I have to use Parmesan cheese?
It’s not required, but Parmesan adds a wonderful salty crunch and flavor complexity. If you want to switch it up, cheeses like Pecorino Romano or sharp cheddar can be great alternatives that bring their own twist to the dish.
