Place the corn vertically on a stable cutting board. Carefully cut the ear of corn in half crosswise. Stand each half upright and cut it lengthwise into quarters. You should end up with 8 “ribs” per ear of corn. Be very careful and use a sharp chef’s knife for this process.
In a large mixing bowl, toss the corn ribs with olive oil, chili powder, smoked paprika, garlic powder, salt, and pepper. Ensure every piece is evenly coated with the oil and spices so they crisp up properly in the air fryer.
Preheat your air fryer to 400°F (200°C). Arrange the corn ribs in the air fryer basket in a single layer, making sure they are not overcrowded. Cook for 10 to 12 minutes. Halfway through, give the basket a good shake. The corn should be tender and the edges should be curled and slightly charred.
While the corn is cooking, prepare the sauce. In a small bowl, whisk together the Greek yogurt and lime juice until smooth. If you prefer a thinner consistency, you can add a teaspoon of water or more lime juice.
Remove the hot corn ribs from the air fryer and place them on a serving platter. Drizzle the Greek yogurt mixture over the ribs. Sprinkle generously with crumbled Cotija cheese and chopped cilantro. Serve immediately with extra lime wedges on the side.
