Cooked right, grilled chicken is juicy, smoky, and deeply flavorful. Cooked wrong, it is charred on the outside and dry on the inside. Both problems can be remedied with this Mediterranean grilled chicken recipe with an easy marinade and a smart grill setup.
The Marinade Does the Heavy Lifting
Boneless, skinless chicken breasts are lean by nature, making them one of the cuts most likely to dry out over high heat. A marinade of extra‑virgin olive oil, lemon juice, garlic, and herbs helps prevent that. The acid in lemon juice tenderizes the meat’s surface, helping it absorb flavor and retain moisture during cooking. Olive oil creates a light protective coating that slows moisture loss and promotes even browning on the grill.
The marinade does double duty for health. Marinating meat can reduce carcinogenic compounds such as heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) that form at very high heat.
One caution: Marinating longer than eight hours can soften the texture of chicken breasts more than most people prefer. Two to four hours is the sweet spot for flavor and juiciness without compromise.
Why Your Grill Setup Matters
The grill matters as much as the marinade. Direct flame contact, such as when fat or marinade drips onto the heat source, increases charring and carcinogens.
Pellet grills and flat-top griddles naturally fix the charring. On a pellet grill, food sits above a drip pan and a heat deflector plate, so it never comes into contact with an open flame, just convective heat and wood smoke. A griddle eliminates flame contact entirely, cooking via a radiant surface heat. Both produce excellent browning and real grill flavor without flare-up problems.
The Mediterranean grilled chicken recipe is designed for grills that have a solid heat shield between the flame and the grates. However, if you have a standard gas or charcoal grill, you can avoid the direct flame by setting up two zones—setting one side to medium-high and leaving the other side unlit. Cook the food over the unlit side with the lid closed, letting the ambient heat do the work. If you want light grill marks at the end, a quick 60 seconds per side over the lit zone is enough. Aim for color, not char.
A few additional steps reduce flare-ups on open-flame grills: Trim visible fat from the chicken before marinating, and shake off excess marinade before placing the pieces on the grill to prevent dripping directly onto the heat source.
Don’t Forget the Veggies
Sweet potato planks and zucchini get their own portion of the same delicious lemon-garlic-and-herb marinade. Unlike muscle meat, vegetables and starchy roots do not form HCAs, so they are inherently safer on the grill. However, they still require attention to charring. Avoid deep blackening, which also concentrates PAHs in plant foods. Gentle caramelization on indirect heat is exactly what brings out their natural sweetness.
How to Make Mediterranean Grilled Chicken, Sweet Potato Planks, and Zucchini
Dried oregano, sage, basil, and marjoram give the marinade a classic Mediterranean flavor that ties together the chicken, sweet potatoes, and zucchini.
Prep Time: 15 minutes
Marinating Time: 30 minutes to 4 hours
Cook Time: 20 to 25 minutes
Serves 4
Ingredients
- 1/3 cup extra‑virgin olive oil
- 1/3 cup fresh lemon juice (about 2 lemons)
- 3 large garlic cloves, minced (preferably fresh, or 1/2 teaspoon garlic powder)
- 1 1/2 teaspoons dried oregano
- 1 1/4 teaspoons fine sea salt
- 1 teaspoon dried basil
- 1 teaspoon rubbed sage
- 1/2 teaspoon dried marjoram
- 1/2 teaspoon red pepper flakes (or less to taste)
- 1/2 teaspoon ground black pepper
- 4 boneless, skinless chicken breasts
- 2 medium orange or purple sweet potatoes, peeled and sliced into 1/2‑inch‑thick planks
- 2 medium zucchini, sliced lengthwise into 1/2- to 3/4-inch thick planks
Instructions
Step 1: In a medium bowl or measuring cup, whisk together the olive oil, lemon juice, garlic, oregano, salt, basil, sage, marjoram, red pepper flakes, and black pepper until well combined.
Step 2: Measure out 1/4 cup of the marinade, transfer it to a small container, and refrigerate it for the vegetables.
Step 3: Place the chicken breasts in a shallow glass or ceramic dish and pour the remaining marinade over the chicken. Cover and refrigerate the chicken for at least 30 minutes and up to 4 hours, turning once.
Step 4: About 30 minutes before grilling, put the sweet potato planks and zucchini in a large bowl. Add the reserved marinade and toss until all sides are lightly coated. Let the vegetables sit at room temperature while the grill preheats.
Step 5: Preheat the grill to medium-high (about 400 F).
Step 6: Remove the chicken from the marinade, letting excess drip back into the dish. Discard the chicken marinade. Place the chicken on the preheated grill. Close the lid and cook the chicken for about three minutes.
Step 7: Add the sweet potato planks and zucchini to the grill. Cover and continue cooking for 15 to 20 minutes, flipping the chicken and sweet potatoes once halfway through and the zucchini once after about seven minutes. Cook until the sweet potatoes and zucchini are tender and the chicken reaches an internal temperature of 165 F.
Step 8: Transfer the chicken and vegetables to a platter. Let the chicken rest for five minutes before slicing.
Notes
Grills vary widely, as do weather conditions. Use the times here as a guide and keep an eye on your food. Grilling is not a set‑it‑and‑forget‑it method.
The thickness of your vegetables will also affect cooking time. Any thinner than listed and they will cook faster and may turn out drier.
Frequently Asked Questions
Q: Can I make Mediterranean grilled chicken with thighs instead of breasts or bone-in instead of boneless?
A: Yes. Boneless, skinless chicken thighs work well with the same marinade, but they typically take a few minutes longer to cook than breasts. For the best texture, cook thighs to about 175 F to 185 F, where they become more tender. If using bone-in pieces, allow additional time and cook until the internal temperature reaches at least 175 F near the bone.
Q: Can I bake the chicken instead of grilling it?
A: Yes. Arrange the marinated chicken on a parchment-lined sheet pan and roast at 400 F for 20 to 25 minutes, until it reaches an internal temperature of 165 F. Roast the sweet potatoes and zucchini on a separate pan for 25 to 30 minutes, until tender.
Q: Can this grilled chicken be reheated for meal prepping?
A: Grilled chicken is best enjoyed fresh off the grill. If you have leftovers, serve them cold over greens or sliced into a wrap. If reheating is necessary, warm gently in a 300 F oven just until heated through. Repeated reheating and multiple freeze-thaw cycles can increase the formation of harmful compounds created when fats and proteins break down under heat. For the best quality and to minimize this effect, thaw and reheat frozen chicken only once.
