Preheat oven to 425ºF/220ºC.Scrub and wash potatoes well. Pat dry. Cut into wedges (each potato was cut into 8-10 wedges) and toss with 2 tbsp olive oil to coat (reserve 1 tbsp for the pan).In a small bowl, stir flour, paprika, garlic powder, onion powder, and salt.Sprinkle over oiled potato wedges and toss to coat.Prepare a baking sheet with the remaining 1 tbsp oil. Arrange potato wedges to stand up on the potato skin side. If some fall over, no big deal!Bake for 35-40 minutes until edges are crisp and golden, and the sides are golden.Remove from heat and serve. Feel free to sprinkle a little extra salt here, or serve with my favourite: ketchup and sriracha sauce.
