Pour the olive oil and vegetable over the veggies and then sprinkle them with the Cajun seasoning and salt.
Either use your hands to mix everything together (my preferred method) or use a large spoon to ensure veggies get coated with oil and seasoning.
Roast the vegetables for 45 to 55 minutes, stirring 2 or 3 times to ensure even cooking.
The vegetables are done when they are cooked all the way through (sample a piece of sweet potato to make sure it’s soft) and have some color to them.
Serve with your favorite hunk of meat.
If you enjoy a nice char or crisp on the outside of your vegetables, you can put your oven on the broil setting after your vegetables are finished roasting and broil them for a few minutes to get a little crisp on.
