I can honestly say I make roasted potatoes all of the time; sweet potatoes, fingerlings, red, russet. They’re easy and you can add just about any seasoning to them and they’ll come out great.
4 c potatoes, peeled and diced
1 tbs olive oil
1 tsp thyme, chopped
1 tsp rosemary, chopped
Kosher salt and pepper to taste
Preheat oven to 400 degrees
Transfer the potatoes to a large bowl. Toss with olive oil. Add remaining ingredients and give them several good tosses until evenly coated. Spread out on a lined sheet pan. Bake for 30 -45 minutes or until the are turning a crispy golden color. Try to refrain from opening the oven too much or touching them, just let them do their thing. Once crispy and golden, remove from oven and serve.
