Make the marinade Whisk together olive oil, soy sauce, lemon juice, brown sugar, minced garlic, Italian seasoning, smoked paprika, black pepper, and salt in a small bowl until the sugar is fully dissolved. Taste it . it should be bold, slightly salty, and tangy. This is your best chicken marinade base.
Reserve basting portion (optional) If you want a sauce for basting during cooking, set aside 3 tablespoons of marinade now before it contacts raw chicken. Store in a small sealed container in the fridge.
Marinate the chicken Place chicken in a gallon zip-top bag. Pour the marinade over the chicken, press out as much air as possible, and seal. Massage the bag so every surface is coated. Refrigerate for a minimum of 30 minutes and up to 6 hours. For overnight, reduce lemon juice to 1 tablespoon.
Remove and dry When ready to cook, remove chicken from the marinade. Pat each piece completely dry with paper towels. This removes surface moisture that would otherwise create steam and prevent browning. The flavor that has penetrated stays in the meat.
Cook to temperature Cook using your preferred method. For the skillet: heat avocado oil in a cast iron skillet over medium high until shimmering, cook 5 to 6 minutes per side. For the oven: bake at 425F for 20 to 25 minutes. For the grill: medium high heat, 6 to 7 minutes per side. All methods are done at 165F internal temperature.
Rest Rest chicken for 5 minutes before cutting. This allows the juices redistributed during cooking to settle back into the meat instead of running out when you cut it.
Serve Slice or serve whole depending on how you are using the chicken. Spoon any reserved basting sauce over the top if using. Serve immediately over rice, with roasted vegetables, or in whatever dish you planned.
