Take a bowl and add shredded chicken. Mix in chopped onion, garlic powder, salt, and pepper. Stir well until everything is combined. This makes the filling flavorful and ready to use.

Heat tortillas lightly in a pan or microwave. This makes them soft and easy to roll. Do not overheat or they may break when rolling.

Take one tortilla and add chicken filling inside. Sprinkle a little cheese on top. Roll it tightly and place it in a greased baking dish. Repeat for all tortillas.

In a saucepan, melt butter on medium heat. Add flour and whisk continuously. Cook for one minute. This forms a smooth base for the sauce.

Pour milk slowly into the butter-flour mixture. Keep whisking to avoid lumps. The sauce will start to thicken as it cooks.

Add sour cream and shredded cheese to the sauce. Stir until smooth and creamy. Add salt and pepper for taste. This creates the rich white sauce.

Pour the creamy white sauce over the rolled tortillas in the baking dish. Make sure everything is covered evenly. This keeps the enchiladas soft and moist.

Preheat oven to 180°C (350°F). Bake for 20–25 minutes. The top should become golden and bubbly.

Remove from oven and let it rest for a few minutes. This helps the sauce settle and makes serving easier.

Serve warm with rice or salad. Enjoy your homemade Chicken Enchiladas with White Sauce recipe.
