Parboil, shake, and roast chunks until they brown into an addictively crunchy, savory side.
There’s something truly irresistible about a perfectly roasted potato—crisp edges, tender interiors, and flavors that make every bite memorable. Whether you’re looking for the ultimate side dish or simply craving comforting potatoes, you’ll find everything you need here. This guide breaks down every step towards achieving true crispy perfection, topped with a melty, garlicky, parmesan butter that brings bold, savory finish to the table.
Why These Are the Best Crispy Potatoes
Few dishes deliver as much crowd-pleasing satisfaction for so little effort as roasted potatoes. But all too often, homemade versions can turn out less than ideal—floppy, dry, or bland. Here’s why this method ensures potatoes that are crisp on the outside and buttery soft inside, plus bursting with layers of garlic and cheese:
- Thorough parboiling creates a fluffy surface for maximum crispness.
- Shaking the potatoes roughs up their edges, essential for crunchy bits.
- Roasting with high heat guarantees deep gold color and shattering texture.
- Finishing with garlic-parmesan butter infuses every bite with flavor, avoiding burnt garlic.
Key Steps to Achieve the Ultimate Crispy Potato
If you’ve struggled with soggy or pale potatoes, don’t worry. It all comes down to a few core techniques:
1. Parboiling with Baking Soda
After cutting the potatoes into hearty chunks, they’re parboiled in salted water spiked with a touch of baking soda. The alkaline water breaks down the potato’s surface, creating a starchy, fuzzy exterior. This rough surface is vital for achieving those desirable crispy golden bits during roasting. Boil until just tender on the outside, but still firm in the center.
- Baking soda helps draw the starch out for a craggier texture.
- Generously salt the water to season the potatoes all the way through.
2. Draining and Shaking
Once parboiled, drain the potatoes thoroughly and return to the hot pot, then shake vigorously. This process both dries off excess moisture and roughs up each piece for maximum crunch potential.
3. Roasting with Hot Fat
Spread the potatoes onto a hot baking sheet coated in oil. The high oven heat (ideally 450°F or 230°C) and preheated pan jump-start browning, giving you a crispy crust. Flip or turn the potatoes halfway through roasting for an all-around crunch.
- Use a neutral oil with a high smoke point—like canola, vegetable, or refined olive oil.
4. The Finishing Touch: Garlic-Parmesan Butter
While the potatoes roast, gently sauté garlic in butter until fragrant but not browned. Stir in a shower of freshly grated Parmesan and finely chopped parsley. This warm, aromatic mixture is tossed with the roasted potatoes right after they come out of the oven, coating each piece with sunshine flavor.

Step-by-Step Recipe
- Prep the Potatoes: Peel if desired; cut into 1- to 1.5-inch chunks for ideal surface area.
- Parboil: In a large pot, combine water, salt (about 2 tablespoons), and baking soda. Bring to a boil, add potatoes, and cook 10–12 minutes until edges are soft.
- Drain and Rough Up: Thoroughly drain potatoes. Return to pot and shake until surfaces are fuzzy and thickened.
- Roast: Preheat oven to 450°F (230°C). Add oil to a large, rimmed baking sheet and heat it in the oven for 5 minutes. Carefully add potatoes (they should sizzle), toss to coat with the hot oil, and spread in a single layer. Roast for 20 minutes, then turn and continue roasting 20–30 minutes more until deeply browned and crisp on all sides.
- Prepare Garlic-Parmesan Butter: While potatoes cook, melt butter in a small skillet over medium-low heat. Add garlic and cook gently just until fragrant; do not brown. Remove from heat, and add parmesan and parsley.
- Finish: Toss roasted potatoes with the warm butter mixture. Season with salt and lots of black pepper as desired. Serve immediately.
Tips and Variations
- Potato Type: Yukon Golds offer a creamy interior and great flavor, while Russets deliver an even crispier exterior. Mix both for variety!
- Additional Herbs: Experiment with chives, dill, or rosemary in place of parsley.
- Spicy Touch: Add a pinch of red pepper flakes to the butter for a gentle heat.
- Citrus Zest: Mix in lemon zest right before serving for a fresh finish.
- Make Ahead: Parboil potatoes up to a day in advance, refrigerating until ready to roast.
Serving Suggestions
Crispy, garlicky potatoes are versatile and complement a huge array of mains. Here are a few ideas to elevate your meal:
- Pair with grilled or roasted meats such as steak, chicken, or pork chops.
- Serve alongside eggs and greens for a hearty breakfast or brunch.
- Build grain bowls with potatoes, roasted vegetables, and a creamy sauce.
- Use as an appetizer with a cool herb yogurt dip or aioli.
The Science of Crispiness
Getting potatoes really crispy is as much about chemistry as cooking. When you parboil with baking soda, the alkaline environment breaks down pectin and exposes starch, giving more surface area for browning reactions during roasting. Meanwhile, roasting at high heat dehydrates the outsides, leading to that shattering crunch. Adding fats like butter after roasting locks in flavor without risking burning delicate aromatics like garlic.
Troubleshooting & Common Mistakes
No one likes soggy potatoes! Here’s how to sidestep the most common pitfalls:
- Potatoes Aren’t Crisping: Make sure the oven is fully preheated and the baking sheet is hot when you add potatoes.
- Potatoes Sticking: Use enough oil, and don’t try to flip too early—let the crust form first.
- Burnt Garlic: Always sauté garlic gently and finish potatoes with the garlic butter off the heat.
- Bland Flavor: Use plenty of salt in the water and season again after roasting.

Frequently Asked Questions (FAQs)
Q: Can I use sweet potatoes instead?
A: Sweet potatoes don’t crisp up quite as much as regular potatoes because of their high sugar content, but you can follow the same method for a delicious result—just expect a softer texture.
Q: How do I store and reheat leftovers?
A: Store cooled potatoes in an airtight container in the refrigerator for up to three days. Reheat in a hot oven or air fryer for best crispiness; microwaving will soften them.
Q: Can I make these vegan?
A: Absolutely! Swap butter for vegan margarine or olive oil, and use a dairy-free parmesan alternative, or omit the cheese completely.
Q: Do I need to peel the potatoes?
A: Peeling is optional. The skin adds texture, flavor, and nutrients, so feel free to leave it on for a rustic look.
Q: My potatoes stuck to the pan—how do I prevent that?
A: Ensure your baking sheet is hot and coated with enough oil before adding potatoes, and don’t turn them too early—let a crust develop before flipping or tossing during roasting.
