Add the thyme, allspice, coconut sugar, sea salt, black pepper, garlic powder, cinnamon, cayenne, olive oil, and freshly squeezed lime juice in a mixing bowl. Stir to combine.
Add the chicken to a 1 quart freezer-safe sealable bag, followed by the jerk spice marinade. Press the air out of the bag and seal tightly, making sure to press the marinade around the chicken to coat.
Place in the fridge to marinate at least 30 minutes, up to overnight.
