Prep the oven and pan: Heat the oven to 375°F (190°C). Lightly spray a 9x13-inch baking dish with nonstick spray.
Spread 1/2 cup enchilada sauce over the bottom of the dish.
Sauté the aromatics: Warm olive oil in a skillet over medium heat. Add onion and cook 3–4 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.
Season the filling: Add cumin, chili powder, smoked paprika, salt, and pepper to the skillet.
Stir for 30 seconds to bloom the spices.
Build the mixture: Add shredded chicken, black beans, and corn. Stir until warmed through, 2–3 minutes. Remove from heat and let cool for 2 minutes.
Make it creamy: Stir in Greek yogurt and 1 cup of the cheese.
Taste and adjust salt if needed. The filling should be creamy but not wet.
Warm the tortillas: Wrap tortillas in a damp paper towel and microwave 30–45 seconds until pliable. This helps prevent cracking.
Assemble enchiladas: Place 2–3 tablespoons of filling down the center of each tortilla.
Roll snugly and arrange seam-side down in the baking dish.
Sauce and cheese: Pour the remaining enchilada sauce evenly over the rolled tortillas. Sprinkle with the remaining 1/2 cup cheese.
Bake: Cover loosely with foil and bake 15 minutes. Uncover and bake another 8–10 minutes, until the cheese melts and the edges bubble.
Finish and serve: Let rest 5 minutes.
Top with cilantro and green onions. Serve with lime wedges.
