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!

I love roasted vegetables but never thought to do it with frozen ones. They turned out great! What a great way to prepare vegetables when you don't have a lot of time.

I cooked 2 pans at a time…1 dark the other lighter. Nice and crispy but the dark pan was blackened more. Note to self, cut back on time when using dark pan.

Do these refrigerate well? Wondering if I cook a bunch for the week they would hold up.

Personally, I find the texture best when made fresh. Luckily they are so easy you could just make a batch for dinner several times a week! It only takes just a couple minutes to prep.
