A classic take onchicken cordon bleu with tender chicken breasts stuffed with ham and Swiss cheese then coated in breadcrumbs, baked and served with a creamy Dijon sauce.
Using a sharp knife, cut each chicken breast in half horizontally to create 2 chicken breast halves. Place 1 chicken breast half between 2 sheets of plastic wrap. Gently pound each piece into an even 1/4-inch thickness, being careful not tear the chicken. Repeat with remaining chicken.
Lay chicken flat on a piece of plastic wrap. Layer 1 slice of ham and then 1 slice of cheese over the chicken, leaving 1/2-inch uncovered around all edges.
Starting on the smaller end of the chicken, roll the chicken tightly, while tucking in the ham and chicken on each side, to the opposite end (like you would a burrito). This will help keep the cheese inside as it bakes.
Wrap the chicken tightly in the plastic wrap, twisting the excess plastic on the sides to create a tootsie-roll shape of a firm chicken bundle. Chill at least 30 minutes or up to 1 day in advance.
Preheat the oven to 400°F. Lightly spray a rimmed 9x13-inch baking sheet with non-stick cooking spray.
In a shallow dish, whisk together the panko, salt, and pepper until combined. Place melted butter in a separate shallow dish.
Remove the plastic wrap from the chicken bundles. Dip 1 bundle into the butter. Transfer to panko mixture, pressing lightly to help the panko stick to the chicken. Transfer to the baking sheet. Repeat with remaining bundles. Spray the panko with nonstick cooking spray.
Bake 30 minutes, or until a digital thermometer inserted into the chicken (not the filling) reads 160°F degrees.
In a small bowl, whisk the mayonnaise and mustard together. Serve with the chicken.
Notes
Cheese: Sharp cheddar or gruyere are other great cheese options.Make-ahead:You can make the wrapped chicken bundles up to one day before breading and baking.Freeze: Place wrapped, uncooked chicken bundles in a freezer-safe container or zip-top bag and freeze up to 3 months. Thaw in the fridge overnight and bread and bake from there.
