Cook the Chicken: Season chicken thighs with salt, pepper, and smoked paprika. Heat olive oil in a skillet over medium-high heat and cook chicken for 5-6 minutes per side until fully cooked. Let rest for 5 minutes, then slice.
Char the Corn: In the same skillet, add corn kernels and cook for 3-4 minutes until slightly charred.
Prepare the Sauce: In a small bowl, mix mayonnaise, sour cream, lime juice, chili powder, and a pinch of salt.
Assemble the Bowl: Divide cooked rice into bowls. Top with sliced chicken, charred corn, and drizzle with the creamy sauce.
Garnish: Sprinkle cotija cheese, cilantro, and lime zest on top. Serve immediately.
