Preheat and prep: Heat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or lightly oil it. This helps prevent sticking and encourages even browning.
Cut the potatoes: Slice each potato in half lengthwise, then cut each half into 3–4 wedges, depending on size.
Aim for similar thickness so they cook evenly.
Soak briefly (optional but helpful): For extra crispiness, soak the wedges in cold water for 10–15 minutes to release excess starch. Drain and pat very dry with a clean towel. Dry potatoes = crispier potatoes.
Make the seasoning mix: In a large bowl, whisk together the olive oil, minced garlic, Parmesan, paprika, onion powder, salt, pepper, and red pepper flakes if using.
Toss to coat: Add the potato wedges to the bowl and toss well, making sure every piece is evenly coated. Don’t be shy—get in there with your hands if needed.
Arrange on the pan: Spread the wedges cut-side down in a single layer with space between them. Overcrowding leads to steaming, not crisping.
Bake: Roast for 20 minutes.
Flip each wedge so the other cut side faces down. Roast another 15–20 minutes, until deeply golden with crisp edges and a tender center.
Finish and serve: Sprinkle with a little extra Parmesan and chopped parsley. Squeeze a bit of lemon over the top if you like a bright finish.
Taste and adjust salt.
