Do you need to thaw frozen vegetables before roasting?

Nope! Actually it is not a good idea to let them thaw at all.

Part of the secret to getting crispy frozen roasted veggies is cooking them straight from frozen at a high temperature.

How do you make frozen vegetables crispy?

The key to crispiness is to not let them thaw, and to roast the vegetables at a high heat.

This is what gets those delicious little crispy edges!

It looks like a really good recipe. I was looking for a recipe to show the chefs of where I live. They're frozen vegetables are horrible. If I could only get them to cook them your way! They cook for about a hundred people so maybe they won't be able to do it.
