The Secret to Extra Crispy Roasted Vegetables

There is a myriad of ways to cook delicious vegetables: boiling, steaming, blanching, stir-frying, grilling. However, roasting is, hands down, most people’s favorite technique. Not only does it bring out the vegetables’ natural sweetness and a deep flavor, but it is also super easy. You don’t even really need a recipe — cooking oil and salt are the only ingredients you need, aside from vegetables themselves.

The best thing about roasted veggies, though, is their texture: crispy on the outside and have a warm and tender center. When prepared well, they can be serious crunchy comfort food on par with French fries.

The Secret Ingredient That Makes Roasted Vegetables Extra Crispy

What’s the secret to achieving that unbelievably addictive extra crunch? As always, ordinary products work miracles. When making roasted vegetables, cornstarch turns into a magical white powder that is pure witchcraft! Though a common ingredient in recipes that require foods to be crispy, for some reason, it’s not a particularly common addition to roasted vegetables. However, once you try this technique, you’ll never go back.

For a perfect crunch every time, follow these steps:

  • Follow your normal roasting process: Peel and chop your veggies of choice into snackable pieces, toss them in olive oil, and season with salt and any other spices you prefer.
  • Add about a tablespoon of cornstarch per pound of vegetables and toss to coat evenly.
  • Roast on a baking sheet or pan. Cooking times and temperatures vary depending on the vegetable, but 20-45 minutes at about 425 F° is pretty standard.

I am an English major with a love of languages and fiction, and with an incurable travel bug. In my free time, I read fantasy, drink copious amounts of coffee, and like to go see movies. Culinary art means everything to me. My main hypostasis is the taster, though. The music school has taught me to appreciate the symphony of airy meringues, to create harmonious overtures of light snacks, hard rock of meat, fish, and vegetables on the grill. Choir classes have accustomed me to hear and feel the people nearby and create perfect harmonies of sounds.
