Preheat oven to 425°F and line a baking sheet with parchment paper. Set aside.
In a small bowl, combine the butter, olive oil, salt, paprika, garlic powder, and onion powder and mix well.
2 tablespoons unsalted butter, 1 tablespoon olive oil, ½ teaspoon kosher salt, ½ teaspoon ground paprika, ½ teaspoon garlic powder, ½ teaspoon onion powder
On a large cutting board, cut each ear of corn in half lengthwise then cut in half again, about 2-inch-wide sections, creating "ribs."
3 ears fresh corn on the cob
Place the ribs on the prepared baking sheet, arranging them in a single layer, with the cut side facing down.
Brush the seasoned butter over each piece of corn.
Bake in the preheated oven for 30-35 minutes, or until the corn ribs are golden brown and crispy.
Remove from the oven and let them cool for a few minutes before serving.
Serve with butter, freshly chopped parsley, and the dipping sauce of your choice.
