I start by adjusting my oven racks, one in the center and another about 6 inches from the broiler. Preheat the oven to 350°F. This ensures the dip cooks evenly and browns perfectly on top later.
In a 10-inch skillet, I heat the olive oil over medium heat. I sauté the white and light-green parts of the scallions with a pinch of salt until softened, about 2–3 minutes. Then I add the corn and seasoning, cooking until slightly tender, 3–5 minutes.
Next, I stir in the cream cheese until smooth, then fold in the sour cream and ¾ cup of the grated Cotija. The mixture becomes creamy and indulgent without being too heavy.
I transfer the skillet to the oven and bake for 10–12 minutes until the edges bubble and turn golden. Then I sprinkle the remaining cheese on top and broil for 2–3 minutes, watching closely to avoid burning.
Finally, I sprinkle the reserved scallion greens and fresh cilantro over the dip. It looks vibrant and tastes amazing right from the skillet.
