Ingredients

Here’s the best part: nearly all of these ingredients are staples in my kitchen. I’m picky about the butter and garlic, though — I’ll explain why.

• Russet potatoes (4 medium, about 2 pounds / 900g) — These have the perfect starchy texture that crisps up wonderfully. Yukon Golds work too if you want a creamier inside.
• Unsalted butter (6 tablespoons / 85g) — I always grab a good-quality butter like Kerrygold for the best flavor. Salted butter can throw off the seasoning balance.
• Fresh garlic (4 cloves, minced / about 1 tablespoon) — No shortcuts here. Fresh garlic makes all the difference in flavor — jarred garlic just won’t do.
• Olive oil (2 tablespoons / 30ml) — Helps the potatoes crisp up nicely without burning the butter.
• Fresh thyme (1 tablespoon, chopped) — Optional but highly recommended. Adds a subtle earthiness that plays perfectly with garlic.
• Salt (1 teaspoon / to taste) — I use kosher salt for even seasoning.
• Black pepper (½ teaspoon / freshly ground) — Just enough to add a little kick.
• Parmesan cheese (¼ cup / 25g, finely grated, optional) — I love sprinkling this on top in the last 10 minutes of baking for a crispy, cheesy finish.

Equipment Needed

You don’t need anything fancy for this. Here’s what I actually use:

• Sharp chef’s knife — Essential for thin, even slices. I keep a paring knife nearby for trimming the potato ends.
• Cutting board — I prefer a sturdy wooden one for better control when slicing.
• Baking sheet or roasting pan — Something with a rim to catch the buttery drips. I use a rimmed baking sheet lined with parchment for easy cleanup.
• Silicone brush — Makes applying garlic butter between the slices so much easier, but you can also use a spoon.
• Small bowl — To mix the garlic butter and herbs.
• Optional: Kitchen chopsticks or wooden spoons — I place these on either side of the potato to prevent slicing all the way through. It’s a trick I swear by.

How to Make Hasselback Potatoes with Garlic for a Crispy Garlic Butter Side Dish

Alright, let’s get into it. I’ll walk you through exactly how I make this, including the small tricks that actually make a difference.

1. Prep the Potatoes (10 minutes)
   Rinse and scrub your russet potatoes well. Pat them dry. To get those perfect thin slices without cutting all the way through, place the potato between two chopsticks or wooden spoons on your cutting board. Slice thinly (about 1/8 inch / 3mm thick) through the potato until your knife hits the chopsticks. You should end up with an accordion-like effect. This keeps the potato intact but allows the butter and garlic to seep in.
2. Make the Garlic Butter (5 minutes)
   In a small bowl, soften your butter (room temperature or gently melted), then stir in the minced garlic, olive oil, chopped thyme, salt, and pepper. The butter should smell garlicky but not overpowering. The olive oil helps the butter crisp up instead of burning.
3. Brush Butter Between Slices (5 minutes)
   Using your silicone brush or a spoon, carefully work the garlic butter in between each slice of the potato. Don’t be shy — this is where all the flavor lives. Make sure each slice gets a little coating. If you have any butter left, brush the outside of the potato too for extra crispiness.
4. Bake Low and Slow (45–50 minutes)
   Place the potatoes on your lined baking sheet or roasting pan. Bake at 425°F (220°C) for 45 minutes to an hour, depending on potato size. About halfway through, baste again with any remaining garlic butter or pan drippings to keep them moist and flavorful. You’ll know they’re done when the slices fan out slightly and the edges turn golden brown and crispy.
5. Add Parmesan For the Final Crispy Kick (Optional, last 10 minutes)
   Sprinkle Parmesan cheese over the potatoes in the last 10 minutes of baking. Return to the oven until the cheese melts and turns golden. This step is optional but adds a deliciously crispy, savory crust that my family loves.

Total time: about 60 minutes. Most of that is baking time, so you have a chance to prep your main dish or relax.

Expert Tips & Tricks

Here’s everything I’ve figured out from making this recipe dozens of times. These tips will save you from the mistakes I already made.

Use Chopsticks to Avoid Slicing Through
This simple trick keeps your slices uniform and the potato intact. Without this, I ended up cutting the potatoes in half more times than I care to admit.

Don’t Skimp on Fresh Garlic
Fresh minced garlic really makes the difference. I tried garlic powder and jarred garlic, but neither gave that bright, punchy flavor that makes the dish sing.

Butter and Olive Oil Combo
Butter alone can burn at high heat. Mixing olive oil helps protect the butter and crisps the edges perfectly.

Baste Halfway Through Baking
This keeps the garlic butter flavor fresh and the potatoes moist. I learned this after a batch came out dry and flavorless.

Parmesan Only at the End
Adding cheese too early makes it burn. Sprinkle in the last 10 minutes to get a golden, crispy finish.

Mistake: Potatoes Are Soggy Instead of Crispy
Fix: Make sure to bake at a high enough temperature (425°F) and baste with the butter mixture. Also, don’t cover the potatoes during baking — that traps steam and softens the edges.

Mistake: Garlic Burns and Tastes Bitter
Fix: Mince garlic finely and mix into butter with olive oil before baking. Avoid adding raw garlic on top halfway through baking.

Variations & Substitutions

Once you’ve got the base version down, here’s how I mix it up. I’ve actually tried all of these.

Herb Mix-Up
Swap thyme for rosemary or sage for a different aromatic profile that pairs beautifully with roasted meats. Rosemary is my go-to for holiday dinners.

Cheesy Upgrade
Try grating sharp cheddar or Gruyère instead of Parmesan. This makes the dish richer and perfect for a comforting weeknight family meal.

Spicy Kick
Add a pinch of red pepper flakes to the garlic butter for a subtle heat. Great for when you want to mix up your usual side dishes.

Lighter Version
Use olive oil instead of butter for a dairy-free option. It won’t be quite as rich but still delicious and crisp.

Dietary Modifications

• Gluten-Free: Naturally gluten-free as long as you check your Parmesan cheese.
• Dairy-Free: Replace butter with vegan butter or extra olive oil, and skip the cheese.

Serving & Storage

I usually serve these Hasselback potatoes straight from the baking sheet — it looks rustic, stays warm, and lets everyone grab as much as they want. They’re perfect alongside roasted chicken or pork, or even with a fresh green salad for a lighter meal.

My favorite sides to pair with these potatoes are garlic bread (obviously — never skip this) or a simple green salad with a tangy balsamic vinaigrette to cut through the richness. When I want to feel virtuous, roasted broccoli is my go-to.

Storage:
Fridge: Store leftovers in an airtight container for up to 4 days. The crispy edges soften but the flavor stays great.
Reheating: Best reheated in a skillet over low heat with a splash of water or olive oil to revive the crispiness. Microwave works in a pinch but the texture won’t be the same.
Freezing: I don’t recommend freezing these — the texture suffers and they lose their crispiness.

Look — this is comfort food made with butter and cheese. It’s not a diet recipe and I’m not going to pretend it is. But it’s way better than takeout, costs less, and I know exactly what’s in it. When I want something lighter, I swap in olive oil and pile on roasted veggies. Most nights though? I make the real thing and enjoy every crispy, garlicky bite.

Final Thoughts

That Thursday night when I first made these Hasselback potatoes with garlic for a crispy garlic butter side dish, I didn’t realize I was starting a new tradition. Now, they’re my go-to when I want a side that’s both impressive and easy. More garlic is always the right call in my opinion. Throw in fresh herbs or swap the cheese for a different flavor twist. The base is forgiving and works with whatever you have on hand.

Frequently Asked Questions

Q: Can I make these Hasselback potatoes with garlic without butter?

A: Yes, you can substitute the butter with olive oil for a dairy-free version. It won’t be as rich, but the potatoes will still crisp up nicely and soak in the garlic flavor. I’ve done this when I was out of butter, and it’s a solid backup.

Q: Why did my Hasselback potatoes turn out soggy instead of crispy?

A: This usually happens if your oven temperature is too low or if you cover the potatoes while baking, trapping steam. Make sure to bake at 425°F (220°C) uncovered and baste the potatoes halfway through with garlic butter to keep them moist but crisp. I learned this after a batch came out soft and disappointing.

Q: Can I make Hasselback potatoes ahead for a holiday dinner?

A: Absolutely! You can prep the potatoes, slice them, and brush with garlic butter up to 6 hours ahead. Cover and refrigerate, then bake just before serving. This saves a lot of stress on the day of. I usually do this when I’m juggling multiple dishes for holiday meals like the Greek chicken gyro bowl I love making.

Q: Are Hasselback potatoes gluten-free and dairy-free?

A: The base recipe is naturally gluten-free. For dairy-free, swap butter with olive oil or a vegan butter substitute, and skip the Parmesan. I’ve made the dairy-free version for a friend with no issues, and it still tastes great.

Q: Can I double or halve this Hasselback potatoes recipe?

A: Yes, this recipe scales well. Just adjust your baking time slightly if you have more or fewer potatoes—larger batches may need an extra 10 minutes. I often double this when I’m meal prepping or hosting guests.

Q: How do I prevent the garlic from burning during baking?

A: Mix the minced garlic into softened butter with olive oil before applying it to the potatoes. This slows down the cooking of garlic and prevents that bitter burnt taste. Adding raw garlic on top midway through baking tends to burn quickly, which I learned the hard way.

Q: Can I add cheese other than Parmesan?

A: Yes! Sharp cheddar, Gruyère, or even mozzarella work well sprinkled on top during the last 10 minutes of baking. I’ve tried all three, and each adds its own twist. Parmesan is my favorite for that classic crispy crust, though.
