Making Smothered Baked Chicken Burritos is a straightforward process. Follow these steps to create this delicious dish:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Chicken Mixture: In a large bowl, combine the shredded chicken, black beans, corn, salsa, cumin, chili powder, garlic powder, and onion powder. Mix until well combined.
3. Fill the Tortillas: Lay out the tortillas on a flat surface. Spoon a generous amount of the chicken mixture into the center of each tortilla.
4. Add Cheese: Sprinkle a little cheese on top of the chicken mixture in each tortilla.
5. Roll the Tortillas: Carefully roll each tortilla tightly, folding in the edges to secure the filling. Place the burritos seam-side down in a greased baking dish.
6. Prepare the Sauce: In a separate bowl, mix the sour cream and enchilada sauce together until smooth.
7. Smother the Burritos: Pour the sauce evenly over the top of the burritos in the baking dish. Top with the remaining cheese.
8. Bake: Cover the baking dish with aluminum foil and bake for 20 minutes. Then, remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.
9. Garnish: Once out of the oven, let the burritos cool slightly. Garnish with chopped cilantro if desired.
