The Science-Backed Secret to Crispy Roasted Potatoes

The Science-Backed Secret to Crispy Roasted Potatoes

As fall approaches, the craving for comfort food kicks in. And let's be honest, few things are as comforting as a plate of perfectly roasted potatoes. But what if I told you there's a secret to achieving ultimate crispiness? It's probably already sitting in your pantry: baking soda.

Why Baking Soda is the Secret Ingredient

Baking soda is the not-so-secret weapon for achieving that coveted crunchy exterior on your roasted potatoes. But how does this pantry staple work its magic?

The Science Behind the Crisp

The science lies in the pH balance. Baking soda raises the pH of the water when you boil your potatoes.

Pectin Breakdown and Surface Area

This higher pH helps break down pectin, the natural "glue" that holds plant cells together. This breakdown creates a rougher, starchier surface area on the potato, which is key to maximum crispiness when roasted. Think of it like creating tiny canyons and valleys for the oil and seasonings to cling to, resulting in extra crunch.

Chef Nick's Tips

Chef Nick Ocando shares his expert advice for crispy roasted potatoes without baking soda.

Dry the Potatoes Thoroughly

Make sure your potatoes are bone dry before seasoning. Excess moisture is the enemy of crispiness, turning your potatoes soggy instead of crunchy.

Avoid Overcrowding

Give your potatoes some breathing room in the roasting pan. Overcrowding steams the potatoes rather than roasting them.

Season Just Before Roasting

Salt draws out moisture, so season right before roasting to minimize sogginess.
