Start by preheating your oven to 425°F (220°C). A hot oven is key to achieving those perfectly crispy fries.
Wash the russet potatoes thoroughly, scrubbing off any dirt. Slice them into wedges, aiming for uniform sizes to ensure even cooking.
In a large mixing bowl, toss the potato wedges with vegetable oil, salt, pepper, and garlic powder until they are well-coated.
Spread the seasoned wedges in a single layer on a large baking sheet. Bake for 30-35 minutes, flipping them halfway through, until they are golden brown and crispy.
While the fries are baking, combine the buffalo wing sauce and butter in a small saucepan over low heat. Stir until the butter is melted and the sauce is well combined.
Once the fries are done baking, remove them from the oven and drizzle the buffalo sauce mixture over the hot fries. Then, sprinkle the sharp cheddar and crumbled gorgonzola cheese on top.
Return the fries to the oven and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly.
Remove the fries from the oven and garnish with sliced green onions, chopped chives, and freshly torn cilantro. Serve immediately and enjoy the crispy buffalo oven fries!
