How to Roast Frozen Vegetables

Roasting frozen vegetables adds flavor you can’t get with steaming; plus, there is little to no food prep, like washing, peeling, or chopping. Here’s what to do:

1. Get the veggies ready
   Add the frozen veggies to a baking sheet. Drizzle with olive oil and season them with salt and roasted veggie seasoning. Toss to combine and spread everything out in an even layer. 
2. Roast
   Bake at 450F for 15 to 25 minutes, depending on the veggie, or until they are cooked through and the edges are golden brown.

Do You Have to Thaw Vegetables Before Roasting?

There’s no need to defrost vegetables before roasting. You can place them directly onto the lined sheet pan from the freezer, season, and bake to perfection.

Tips for Best Roasted Frozen Vegetables

No matter the vegetable you choose to roast, these tips apply and ensure perfectly cooked veggies that don’t taste plain or like they came from the freezer.   

Give them room
Crowding the veggies will cause them to steam so make sure to spread them out onto a large baking sheet leaving space in between each piece. 

Season as usual
Don’t skip the olive oil and veggie seasoning! It adds flavor -something essential to not give them the out-of-the-bag taste and texture.

Separate the veggies
If the veggie pieces are stuck together, do your best to separate them before cooking.
