Garlic Parmesan Potato Wedges
Crispy, golden, and perfectly seasoned, these baked garlic parmesan potato wedges are fluffy on the inside and incredibly crispy on the outside.
- Alkaline parboiling breaks down surface pectin to create a starchy paste that bakes into an ultra-crispy exterior.
- High-heat roasting mimics the texture of deep-fried crispy fries without the messy oil cleanup.
- Freshly grated Parmigiano-Reggiano acts as a dry barrier, absorbing excess moisture while adding a rich, savory umami punch.
My first apartment in Chicago had a kitchen the size of a bathmat, a temperamental oven that ran fifty degrees hot, and a roommate who survived entirely on frozen crinkle-cuts. One rainy Tuesday, determined to prove I could cook real food, I tried making potato wedges from scratch. I hacked three russets into clumsy chunks, tossed them in cheap oil, and watched in horror as they fused into a soggy, carbonized mass on my warped baking sheet.
I actually cried over those sad, limp spuds.
The physics of a perfect potato wedge is surprisingly unforgiving. Raw potatoes thrown straight into a hot oven trap moisture inside, leaving you with a soggy, sad mess.
Here is the simple fix: parboil them first in alkaline water. Adding a pinch of baking soda to the boiling water breaks down the potato's exterior pectin, creating a starchy slurry on the surface of each wedge. When you vigorously shake them in a bowl, this slurry dries out in the oven to create an incredibly textured, micro-crispy crust that clings to the seasonings.
Trust me on this one, it is a total game-changer.
Garlic Parmesan Potato Wedges
Ingredients
- 4 large Russet potatoes (about 2 lbs), scrubbed and cut into 8 wedges each
- 1 tsp baking soda
- 1 tbsp Diamond Crystal kosher salt (for the boiling water)
- 3 tbsp extra virgin olive oil
- 1 tsp garlic powder
- 1 tsp onion powder
- 1/2 tsp smoked paprika
- 1/2 tsp freshly cracked black pepper
- 1/2 cup freshly grated Parmigiano-Reggiano cheese
- 2 tbsp finely chopped fresh flat-leaf parsley
- 1 pinch flaky sea salt for finishing
Directions
- Preheat your oven to 425°F (218°C) and line a large, heavy-rimmed baking sheet with parchment paper.
- Bring a large pot of water to a boil, then stir in the baking soda and Diamond Crystal kosher salt.
- Carefully lower the potato wedges into the boiling water and cook for exactly 8 minutes, until the edges are slightly tender but the wedges still hold their shape.
- Drain the potatoes thoroughly in a colander, letting them steam-dry for 2 minutes to remove excess surface moisture.
- Transfer the warm potatoes back into the dry pot, drizzle with olive oil, and add the garlic powder, onion powder, smoked paprika, and black pepper.
- Place the lid on the pot and shake it vigorously for 5 seconds to rough up the edges of the potatoes, creating a starchy coating.
- Arrange the wedges in a single layer on the prepared baking sheet, ensuring they do not touch so they roast instead of steam.
- Bake for 20 minutes, then use metal tongs to carefully flip each wedge.
- Sprinkle the freshly grated Parmigiano-Reggiano evenly over the wedges and return to the oven for another 10 to 15 minutes, until deeply golden and crispy.
- Remove from the oven, garnish immediately with fresh chopped parsley and a pinch of flaky sea salt, and serve hot.
Notes
- We highly recommend using Diamond Crystal kosher salt; if you are using Morton's kosher salt or fine table salt, cut the volume by half to avoid over-salting.
- The addition of baking soda raises the pH of the boiling water, which accelerates the breakdown of the potato's surface starch into a starchy paste that crisps up beautifully in the oven.
- Do not add the grated parmesan cheese at the very beginning of baking; the cheese will burn and turn bitter before the potatoes have a chance to fully cook and crisp.
- I tested this with pre-shredded cheese from the grocery store, and it failed miserably because of the anti-caking cellulose coating. Always grate your own cheese from a block.
- Leftover wedges will lose their signature crunch in the refrigerator as the starch retrogrades, but they can be easily revived to their former glory in a hot air fryer or oven.
Serving Suggestions
These crispy wedges are incredibly versatile and pair beautifully with a wide variety of mains, dipping sauces, and fresh salads.
- Serve them alongside a juicy crispy air fryer chicken wings platter for the ultimate game-day feast.
- Pair them with a comforting plate of garlic butter chicken to soak up all those delicious, savory pan juices.
- Dunk them into a homemade garlic aioli, spicy ketchup, or a tangy ranch dressing.
- Balance the rich, cheesy flavors with a bright, refreshing Greek salad on the side.
Storage and Reheating
Let's be completely honest here: potatoes are always best eaten fresh out of the oven.
If you do end up with leftovers, store them in an airtight container lined with a paper towel to absorb excess moisture. They will keep in the fridge for up to four days.
To reheat, avoid the microwave at all costs unless you enjoy eating sad, soggy cardboard. Instead, pop them into an air fryer at 380°F (193°C) for 4 to 5 minutes, or spread them on a baking sheet and bake at 400°F (204°C) until they sizzle and the cheese crisps up again.
They will taste almost as good as day one.
Ingredient Substitutes
If you don't have everything on hand, here are a few easy swaps that won't ruin your dinner:
- Russet Potatoes: You can substitute with Yukon Gold potatoes for a creamier, naturally buttery interior, though they won't get quite as thick of a crust as Russets.
- Parmigiano-Reggiano: Pecorino Romano works beautifully as a salty, tangy alternative, or use nutritional yeast for a dairy-free option.
- Garlic Powder: If you want to use fresh garlic, toss it with the parsley at the very end of baking so it doesn't burn in the high-heat oven.
- Olive Oil: Any high-smoke-point oil like avocado oil, canola oil, or even melted duck fat will work perfectly.
I hope these crispy spuds bring as much joy to your table as they do to mine. Let me know in the comments if you tried the parboiling trick—it really is life-changing!
