Prep your potatoes and carrots. You can choose to peel potatoes and carrots or not. I peel them and trim off the carrot ends.
Cut Carrots into half lengthwise. Quarter potatoes or half or cut smaller, depending on the size of your potatoes. The potatoes should be the same size and not too large or they won't cook through on time. I cut mine into 2 inch sized potato pieces.
Preheat your oven to 350° Fahrenheit/ 180° Celsius.
Combine in a bowl the salt, black pepper, garlic powder, and olive oil.
Add carrot and potato pieces to the seasoned olive oil and coat.
Spread coated vegetables over a sheet pan.
Roast at 350° Fahrenheit/ 180° Celsius for about 25-30 mins or until cooked through or golden.
