• In a mixing bowl, whisk together the mayonnaise, avocado oil, Dijon mustard, soy sauce, thyme, sea salt, black pepper, and cayenne until the mixture is smooth and well blended. This marinade will infuse the chicken with savory depth and subtle heat.
• Place the chicken breasts into a shallow dish or sealable plastic bag and coat them thoroughly with the marinade. Cover or seal, then refrigerate for at least 4 hours—or overnight for deeper flavor penetration.
• When ready to cook, remove the chicken from the marinade and discard any leftover liquid.

Blackstone Flattop Griddle

• Preheat the Blackstone griddle to a low to medium setting, aiming for a surface temperature around 350°F. Lightly drizzle or spray avocado oil over the cooking surface to prevent sticking.
• Place the marinated chicken on the hot griddle. Let it cook undisturbed for 7 minutes to develop a seared, golden crust. Flip the chicken and cook for an additional 7 to 10 minutes, or until an instant-read thermometer inserted into the thickest part reads 160°F.
• Transfer the cooked chicken to a plate and cover loosely with foil. Allow it to rest for 5 to 10 minutes before slicing and serving. This step helps retain moisture and ensures tender results.

Stovetop Instructions

• Heat a tablespoon of avocado oil in a large skillet over medium heat. Add the chicken breasts and cook for 7 minutes without disturbing to achieve a good sear.
• Flip the chicken and continue cooking for another 7 to 10 minutes, or until the internal temperature reaches 160°F. Transfer to a plate and let it rest for 5 minutes before serving.
