Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large skillet, heat the olive oil over medium heat. Sauté the diced onion until translucent, about 3-4 minutes.
Add the minced garlic to the skillet and cook for an additional minute until fragrant.
Stir in the shredded chicken, black beans, corn, cumin, chili powder, smoked paprika, salt, and pepper. Cook for another 5 minutes, allowing flavors to meld.
Remove the skillet from heat and stir in half of the shredded cheese to the chicken mixture, allowing it to melt slightly.
Take a flour tortilla and spoon about ½ cup of the filling onto the center. Fold the sides over the filling, then roll it up tightly to create a chimichanga. Repeat with the remaining tortillas and filling.
Place the chimichangas seam-side down on the prepared baking sheet. Lightly spray the tops with cooking spray or brush with olive oil to ensure they crisp up while baking.
Bake in the preheated oven for 20-25 minutes, or until golden and crispy. Flip halfway through for even browning.
Remove from the oven and let them cool slightly before serving, garnished with the remaining shredded cheese, sour cream, guacamole, salsa, or chopped cilantro as desired.
Notes
Serve with optional toppings like sour cream, guacamole, and salsa.
