Ingredient Substitution Guide

1. Step 1

   Start by flattening the chicken breasts: Place a breast smooth side down on a cutting board, with the thick end at the top and the pointy end at the bottom. Cut a deep slit — without cutting all the way through the meat — down the center of its length. Pry open the slit, turn the knife blade to the left, parallel to the board, and slice perpendicular to the initial cut without cutting all the way through the meat. Repeat on the right side to end up with two flaps that open out from the center like window shutters to form a broader, flatter piece of meat. Use your palm to smack the lumpy parts flat, but don’t pound so hard that you tear the meat. Repeat with the remaining breasts.

2. Step 2

   Make the marinade: Use a fine grater to zest the lemon directly over a large bowl or airtight container, then run the garlic cloves over the grater. Squeeze in the juice from the lemon, then stir in the herbs, oil, salt and pepper. 

3. Step 3

   Marinate the chicken: Add the flattened chicken and turn and rub it evenly with the marinade. Let stand at room temperature for at least 15 minutes if grilling right away or cover and refrigerate for up to 4 hours. If chilled, take it out of the fridge right before heating the grill.

4. Step 4

   Prepare the grill: Heat an outdoor grill to the higher side of medium-high. When it’s ready, you should be able to hold your hand 5 inches above the grate for 3 to 5 seconds. If the grill grates aren’t already clean, use a grill brush to remove anything stuck to them. Oil a wadded up paper towel, grip it with tongs and rub it over the grate. (See Tip for indoor cooking.)

5. Step 5

   Set the chicken and any marinade clinging to it on the oiled grate, spreading each piece in a single, even layer. Cook, covered if using a gas grill, until the bottom is deeply browned and releases easily from the grate, 3 to 5 minutes. Flip each piece and cook until a paring knife inserted in the center reveals meat that’s just opaque throughout but still juicy, 2 to 3 minutes longer. Transfer to a platter and rest for about 5 minutes before slicing and serving with lemon wedges for squeezing. Leftovers can be refrigerated in an airtight container for up to 5 days.

Tip

• You also can use a cast-iron grill pan on the stovetop. Heat it over high and lightly oil it before adding the chicken. Cook in batches if needed, turning the meat when it releases easily from the pan, until the meat is opaque but still juicy.
