The Secret Behind Extra Crispy Roast Potatoes
Ever wonder why restaurant potatoes seem crunchier than homemade versions?
The answer is surprisingly simple.
Adding a small amount of baking soda to the boiling water helps break down the potato surface. As the potatoes cook, the outer layer becomes slightly starchy and rough. When roasted in hot fat, those rough edges transform into crunchy golden bits that are downright addictive.
Then comes another secret weapon: shaking the potatoes after draining. It may feel odd, but those rough edges are exactly what create that incredible crunch.
Trust the process—it works beautifully.
How to Make Crispy Roast Potatoes with Rosemary and Garlic
Step 1: Preheat the Roasting Pan
Place a large roasting pan in the oven and preheat to 450°F.
Heating the pan first gives the potatoes an immediate sizzle when they hit the fat, helping them develop a crisp crust right away.
Step 2: Parboil the Potatoes
Rinse the potato chunks under cold water to remove excess starch.
Transfer them to a large pot and cover with cold water. Add the kosher salt and baking soda.
Bring everything to a boil over high heat. Cook until the potatoes are just fork-tender and the edges begin to break down slightly, about 25 minutes.
Drain thoroughly and let them sit in the colander until completely dry.
Step 3: Rough Up the Edges
Give the colander a few gentle shakes.
The potatoes will look a little messy and fuzzy around the edges. That’s exactly what you want.
Those rough surfaces become crispy little pockets of golden perfection during roasting.
Step 4: Roast Until Golden
Carefully remove the hot roasting pan from the oven.
Add your chosen fat and allow it to melt or heat through.
Transfer the potatoes to the pan and season lightly with salt and pepper. Toss gently to coat.
Place the garlic head cut-side down among the potatoes.
Roast for 55 to 60 minutes, turning the potatoes every 20 minutes.
By the end, they should be deeply golden, crunchy, and beautifully caramelized.
Step 5: Add the Garlic and Rosemary
Remove the roasted garlic from the pan.
Squeeze the softened cloves into a small bowl. Add the chopped rosemary and olive oil or butter.
Mash everything together with a fork until a rustic paste forms.
Toss the mixture with the potatoes and return the pan to the oven for another 5 minutes.
This final step infuses every potato with rich roasted garlic flavor and fragrant rosemary.
Step 6: Finish and Serve
Taste and adjust seasoning as needed.
Sprinkle with flaky sea salt just before serving for an extra layer of texture and flavor.
Serve immediately while they’re hot and crispy.

Chef Omar’s Tips for Perfect Roast Potatoes
Let the Potatoes Dry Completely
Moisture is the enemy of crispiness.
After draining, allow the potatoes to sit for a few minutes so excess steam can escape.
Don’t Crowd the Pan
Give each potato some breathing room.
Overcrowding causes steaming instead of roasting, which can lead to softer results.
Use High Heat
The 450°F oven temperature is essential for creating those deeply golden, crunchy edges.
Choose the Right Fat
Duck fat is traditional and incredibly flavorful, but olive oil, avocado oil, beef tallow, or ghee all work wonderfully.
One home cook mentioned using a mixture of butter and canola oil when duck fat wasn’t available—and the results were still absolutely delicious.

No one waited for the main course.
Since then, they’ve become my reliable side dish whenever I want something comforting, crowd-pleasing, and guaranteed to disappear fast.
What to Serve with Crispy Roast Potatoes

Frequently Asked Questions
Can I make Crispy Roast Potatoes with Rosemary and Garlic ahead of time?
Yes. Parboil the potatoes and refrigerate them up to one day ahead. Roast just before serving for the best texture.
What potatoes work best?
Yellow potatoes are excellent because they offer a creamy interior while still developing crisp edges. Yukon Gold potatoes are a fantastic choice.
Can I use dried rosemary?
Fresh rosemary provides the brightest flavor, but dried rosemary can be substituted if needed. Use about one teaspoon of dried rosemary.
How do I store leftovers?
Store leftovers in an airtight container in the refrigerator for up to 4 days.
How do I reheat them?
For maximum crispiness, reheat in a 425°F oven or air fryer rather than using a microwave.

One cook noted that following the rough-edge technique produced beautifully crisp potatoes with excellent results.
