Put ½ pound chicken breasts inside a Ziploc bag or between two sheets of parchment paper. Gently pound the chicken using a meat tenderizer or heavy rolling pin until it's even in thickness. Repeat for the other ½ pound chicken breasts. Place the chicken in a gallon size Ziploc bag, or a shallow glass or ceramic dish and set it aside.
Whisk together the marinade ingredients (2 tablespoons olive oil, 1 teaspoon salt, ½ teaspoon black pepper, and ½ teaspoon garlic powder). Pour the marinade over the chicken, turning to coat. Marinate at room temperature for 30-60 minutes, or in the refrigerator for up to 12 hours
Turn your grill to medium heat and let it preheat. Add the chicken breasts to the grill, cooking for about 6 minutes on each side. When the internal temperature of the chicken reaches 165℉, remove chicken from the grill and let it rest for 5-10 minutes before slicing.
Make the Dressing
In a medium bowl, whisk together 1 clove garlic (minced), ¼ teaspoon anchovy paste, ¼ teaspoon Dijon mustard, ¼ teaspoon Worcestershire sauce, 1 teaspoon lemon juice, and ⅓ cup mayonnaise until smooth.
While whisking constantly, slowly drizzle in 3 tablespoons olive oil until the dressing thickens, emulsifies, and becomes creamy.
Whisk in the 1 tablespoon finely grated Parmesan cheese and ⅛ teaspoon black pepper. Taste and adjust with additional lemon juice or ⅛ teaspoon salt if desired.
Use immediately or refrigerate for 20–30 minutes to let the flavors meld.
Assemble the Salad
Divide 8 cups romaine lettuce, 5 ounces croutons, and ½ cup shaved Parmesan cheese among four large bowls. Top each salad with 4 ounces chicken and cracked black pepper. Serve and enjoy!
Notes
The Caesar salad dressing ingredients shown are enough to lightly dress 4 chicken Caesar salads. If you like a lot of dressing, make my homemade Caesar salad dressing recipe, which yields 1.5 cups of dressing.
