Unstuffed Chicken Cordon Bleu

 

1 T. olive oil

4 (6- to 8-ounce) boneless, skinless chicken breasts

2 T. Dijon mustard

4 slices (4 ounces) deli ham

1 cup (4 ounces) shredded Gruyere cheese

1 Ritz crackers (1 % ounces)

 

Adjust oven rack to lower-middle position and heat oven to 475 degrees. Brush rimmed baking sheet with oil. Trim chicken, pat dry with paper towels, season with pepper, and arrange on prepared sheet. Spread mustard over top of chicken, then top each breast with 1 slice ham, folded in half, and 1/44 cup Gruyere. Coarsely crush crackers and sprinkle over top, pressing on crumbs to adhere. Bake until chicken registers 160 degrees, about 20 minutes, rotating sheet halfway through baking. Serve.
