Instructions
1. Marinate the Chicken:
Whisk all marinade ingredients in a bowl. Add sliced chicken thighs and coat well. Cover and refrigerate overnight for maximum tenderness and flavor.
2. Make the Aioli:
Mix all aioli ingredients together. Let chill for at least 1 hour, preferably overnight, to allow flavors to develop.
3. Caramelize the Onions & Toast the Buns:
Melt butter on your griddle or skillet. Add sliced onions and cook low and slow until golden and soft. While onions cook, mix your garlic butter and apply to your bread. Toast your hoagie rolls cut side down until golden brown.
4. Season & Cook the Chicken:
Remove chicken from the marinade, pat dry, and toss in your seasoning blend. Cook the chicken on medium-high heat until caramelized and fully cooked.
5. Combine Chicken and Onions:
Lay the cooked chicken and onions into a line the length of your hoagie rolls.
6. Cheese Melt:
Top each pile with 2 slices white American cheese, 1 half-slice of provolone on each end, and a generous spoonful of garlic herb cream cheese. Cover with a lid or melt dome until gooey. Flip the pile briefly to crisp the cheese, then mix together into one cheesy mass.
7. Assemble the Sandwich:
Place the toasted roll on top of the filling. Slide your spatula underneath, flip it, and lay it onto your board like you’re laying down bricks. Slice and serve.
