Extra Crispy Roasted Little Potatoes with Cornstarch Coating

These golden little potatoes achieve exceptional crispiness through a clever cornstarch coating technique that creates an irresistibly crunchy exterior while keeping the interior fluffy. The combination of olive oil and cornstarch forms a protective shell that crisps beautifully in high heat, while garlic powder adds savory depth. Perfect as a side dish for weeknight dinners or holiday meals, these potatoes pair wonderfully with roasted meats or can stand alone as a satisfying snack.

FAQ

Can I use regular potatoes instead of little potatoes?

Yes, cut regular potatoes into 1-inch pieces for similar cooking time and texture.

What if I don't have cornstarch?

Potato starch works similarly, or skip it for less crispy but still delicious potatoes.

How long will these keep in the refrigerator?

Store covered for up to 3 days, though they're best reheated in the oven to restore crispiness.
