01 - Preheat oven to 400°F. Line a baking sheet with aluminum foil and lightly grease the surface.
02 - Slice each chicken breast in half horizontally, then cut into 8 equal-sized portions for even cooking.
03 - In a mixing bowl, whisk together the maple syrup, Dijon mustard, soy sauce, olive oil, salt, and pepper until well combined.
04 - Toss the chicken portions in the maple glaze, ensuring each piece is evenly coated. Allow to rest for 10–15 minutes at room temperature.
05 - Arrange the bacon slices on the prepared baking sheet and bake for 12–15 minutes until golden and crisp. Transfer to paper towels to drain excess fat.
06 - Heat a grill pan or cast-iron skillet over medium-high heat. Sear the marinated chicken pieces for 3–4 minutes per side until cooked through and deeply caramelized.
07 - Brush the cut sides of each bun with melted butter. Toast on a hot skillet or grill pan until golden brown, about 1 minute per side.
08 - Layer arugula, a chicken portion, a strip of bacon, a slice of cheese, and a few rings of red onion on each bottom bun. Cap with the top bun.
09 - Secure each slider with a cocktail pick and serve immediately while warm.
