Preheat oven to 400°F.

Marinade: In a small bowl, whisk together mustard, honey, mayonnaise, and lemon juice. Reserve ¼ cup sauce in a covered container and refrigerate until serving time. Meanwhile, place the chicken breast in a large Ziploc® bag. Pour in remaining sauce and turn in bag until evenly coated. Refrigerate 30 minutes or overnight.

In a large oven-proof skillet over medium-high heat, heat oil until shimmering. Add chicken (discarding any remaining marinade) in a single layer and do not flip until a golden-brown crust forms, about 5 minutes. Flip each piece and continue to cook until the second side is browned, about 5 minutes longer.

Top with bacon and cheese. Cover the skillet and place in the oven. Bake until the chicken reaches 165°F when tested with an internal thermometer at the thickest part, about 10 to 15 minutes. Remove from oven.

Serve with reserved sauce on the side for dipping and enjoy!
