To make these Creamy Baked Chicken Chimichangas gluten free, replace the flour tortillas with certified gluten-free tortillas. Verify that the taco seasoning, cream cheese, Monterey Jack cheese, chicken, butter spray or melted butter, and nonstick cooking spray are gluten free. Use clean utensils, bowls, baking sheets, and prep surfaces to avoid cross-contact with gluten-containing ingredients.
