Creating delicious Baked Chicken Chimichangas is simple when you follow these steps:

1. Preheat Oven: Start by preheating your oven to 400°F (200°C). Prepare a baking sheet by lining it with parchment paper.

2. Prepare Filling: In a large mixing bowl, combine the shredded chicken, black beans, corn, cheese, taco seasoning, garlic powder, onion powder, cumin, salt, and pepper. Mix well until all ingredients are evenly incorporated.

3. Assemble Chimichangas: Lay a tortilla flat on a clean, dry surface. Add a generous portion of the filling (about ½ cup) to the center of the tortilla.

4. Fold the Tortilla: Fold in the sides of the tortilla over the filling, then roll it tightly from the bottom to the top. Secure it by placing the seam-side down on the baking sheet. Repeat this for the remaining tortillas and filling.

5. Brush with Oil: Lightly brush the tops of the chimichangas with olive oil to encourage browning and crispness.

6. Bake: Place the baking sheet in the preheated oven. Bake for 30-35 minutes, or until the chimichangas are golden brown and crispy.

7. Cool: Once baked, remove the chimichangas from the oven and allow them to cool for about 10-15 minutes.

8. Serve: Plate the chimichangas and serve hot with your favorite toppings such as salsa, guacamole, sour cream, and fresh cilantro.
