Everything from roasted fall vegetables to carrots and parsnips has become some of my favorites sides. But on nights when you don’t feel like peeling, chopping, or doing any food prep, I’m here to tell you that frozen vegetables can come to the rescue! 

You can roast just about any frozen vegetable, and in this post, I’m sharing my tips and tricks to make sure they turn out perfect every time. 

How to Roast Frozen Vegetables

Roasting frozen vegetables add flavor you can’t get with steaming; plus, there is little to no food prep like washing, peeling, or chopping.

Once you have your ingredients ready, here is how to roast frozen vegetables:

1. Prep
   Preheat the oven to 450F. 
2. Get the Veggies Ready
   Add the frozen veggies to the 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. 
3. Roast
   Bake for 15 to 25 minutes, depending on the veggie, or until they are cooked through and the edges are golden brown.

Do I line the baking sheet when roasting frozen vegetables?

You do not have to line the baking sheet when roasting frozen vegetables IF you separate your veggies well and generously spray your pan.

If you’re not using much oil on your vegetables, line the pan to prevent sticking.

The biggest advantage to lining your pan is the easy cleanup!

Will Frozen Vegetables Get Crispy?

Since they’ve been flash-cooked, frozen veggies will be slightly softer than fresh when roasted. However, they still get those golden, brown edges and nutty flavor.

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.

Make sure the oven is fully preheated
The 450F is kind of high heat for this recipe, but it helps the water evaporate quickly, and the edges get as golden and crisp as possible.

Don’t line baking dishes
Glass and ceramic baking dishes don’t need to be lined, just sprayed with oil. You want the veggies to cook directly on the hot surface, it helps them brown, and the liquid evaporates. 

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