Step 1

Preheat oven to 375 degrees. Place a large, rimmed baking sheet on center rack to heat up along with the oven.

Step 2

Cut the vegetables into uniform pieces, about 1-square-inch for each piece. Place all vegetables in a large bowl and drizzle with the olive oil. Toss to coat and season with salt and pepper, to taste.

Step 3

Once the oven is preheated, (carefully!) pour prepared vegetables onto the hot pan and spread into an even layer. Bake for 75 – 90 minutes, tossing 35 minutes into cooking so that vegetables evenly brown. Remove from oven when vegetables are browned and crispy and serve immediately.
