Preheat your oven to 375 degrees Fahrenheit and prepare a large sheet pan by lining it with parchment paper or spraying it with non stick cooking spray.
Add all the chopped veggies to a large bowl.
Add the olive oil, salt, pepper, and garlic powder and toss very well.
Add the veggies to the large sheet pan. Avoid overcrowding them and place them in a single layer.
Roast at 375 degrees Fahrenheit for about 15-16 minutes. If your oven roasts unevenly, toss the veggies once about halfway through roasting or rotate your pan.
Serve immediately.
Notes
How to chop the veggies so they cook evenly
When using multiple kinds of veggies in the same dish, we recommend chopping them strategically so they cook evenly. This means for harder vegetables (like carrots), we slice them more thinly. For softer vegetables (like bell peppers), we chop them in larger pieces. This way the vegetables become tender all at the same time and you avoid over-cooking some while under-cooking others.

How to reheat Roasted Vegetables
These roasted vegetables can be reheated in the oven on a sheet pan until heated through, in the microwave, or in the air fryer for 3-4 minutes.
