Sheet Pan Oven Roasted Mixed Vegetables are the best way to cook vegetables. Crispy on the outside and tender on the inside, this cooking method makes vegetables so tasty that even picky eaters love them!
Preheat oven to 375 degrees. Place a large, rimmed baking sheet on center rack to heat up along with the oven.
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.
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.
