With ham, swiss, and a flavorful breading, this easy chicken cordon bleu is simple enough to make on a weeknight and fancy enough for a romantic Valentine's Day dinner! You can even make ahead of time and bake the day of. It's so juicy and flavorful!
Fold each slice of swiss cheese accordion-style to make a cheese stick about half an inch wide.
Place a cheese stick on a piece of ham long-ways. Fold ends of ham over ends of cheese stick and roll up like a burrito. Repeat with remaining slices to make six ham and cheese rolls. This keeps the cheese from melting out while baking.
Combine bread crumbs with onion soup mix in one flat-bottomed bowl or tray. Put mayonnaise in another. Dredge the smooth side of each piece of chicken in mayo, then in the bread crumb mixture.
With the uncoated side of the chicken facing up, place a ham and cheese roll in the center short-ways. Fold each end of the chicken over the ham roll and place in a 9x9 baking pan with the open seam facing down. You will not need toothpicks to secure.
Bake for 45 minutes. Enjoy with a glass of white wine!
Chicken can be prepared a day ahead and baked the next day. Remove the pan of chicken from the refrigerator while oven preheats and then bake as directed.
