Greek Chicken Breast Recipe Oven: Mediterranean Herb-Infused and Juicy

This oven-baked Greek chicken breast delivers juicy, herb-infused perfection every time. The secret lies in a simple marinade that keeps the meat tender while building authentic Mediterranean flavor.

I developed this method after years of dry, overcooked chicken. A quick brine followed by high-heat roasting locks in moisture while creating a golden crust. Fresh oregano, lemon, and garlic form the flavor base.

You’ll achieve restaurant-quality results with minimal effort. The chicken emerges perfectly cooked with fragrant herbs and citrus notes throughout, ready to serve with flatbread or salad.

This dish works for weeknight dinners or weekend gatherings. The hands-off oven method ensures consistent success.

Ingredients for Greek Chicken Breast Recipe Oven

Pantry staples and fresh Mediterranean herbs create this oven-baked masterpiece with minimal effort.

The chicken quality is paramount. Boneless, skinless breasts from Whole Foods or Costco offer consistent thickness and freshness. For optimal results, select pieces that are uniformly sized (about 6-8 oz each). The fresh oregano should have vibrant green leaves with a strong citrusy aroma—avoid any bunches with wilting or yellowing. Extra-virgin olive oil from California Olive Ranch provides the clean, fruity base this marinade requires.

No fresh oregano? Dried Mediterranean oregano at one-third the amount works, though the flavor profile will be more concentrated. Regular dried oregano can substitute in a pinch, but expect a slightly earthier taste. For the yogurt, Fage full-fat Greek yogurt is ideal, but any thick, unsweetened variety will tenderize effectively. The lemon can be swapped for lime, though the dish will lose some of its classic Greek character.

Marinated chicken keeps in the refrigerator for up to 24 hours before cooking. Leftovers store well for 4-5 days and reheat beautifully in the microwave or oven. For best results, allow cooked chicken to rest at room temperature for 10 minutes before slicing and serving.

Step-by-Step Instructions for Greek Chicken Breast Oven

Here is the tested method for achieving perfectly juicy, herb-infused chicken every time.

Step 1: Prepare the Marinade with Mediterranean Flavors

In a large bowl, whisk together the 0.33 cup extra-virgin olive oil, 0.25 cup fresh lemon juice, 0.25 cup fresh oregano, 4 cloves garlic cloves, 1 tsp dried thyme, 1 tsp dried rosemary, 1 tbsp lemon zest, 1 tsp freshly ground black pepper, and 1 tsp kosher salt. The herbs should release their aromatic oils as you mix.

Add the 0.5 cup plain Greek yogurt and whisk until fully incorporated. This creates a thick, flavorful base that will tenderize the chicken while infusing it with bold Mediterranean character. The mixture should be slightly emulsified with no oil separation.

Step 2: Marinate the Chicken for Maximum Flavor

Add the 1.5 lb boneless skinless chicken breasts to the marinade, ensuring each piece is fully coated. I use a fork to pierce the chicken slightly—this allows the marinade to penetrate deeper. Cover and refrigerate for at least 2 hours, or preferably overnight.

The chicken should take on a pale yellow hue from the lemon and herbs. Don’t skip this step; the marinating time is what delivers the juicy, flavorful result promised. The yogurt’s lactic acid works to break down proteins gently, ensuring tenderness.

Step 3: Roast the Chicken to Juicy Perfection

Preheat your oven to 400°F. Remove the chicken from the marinade (shaking off excess) and place it on a wire rack set over a baking sheet. This elevation allows hot air to circulate around the entire piece, preventing steaming and promoting even browning.

Roast for 20-25 minutes, or until the internal temperature reaches 165°F and the juices run clear. The chicken should have a light golden crust from the olive oil and herbs, with the oregano and rosemary visibly caramelized on the surface.

Step 4: Rest and Garnish for Serving

Transfer the chicken to a cutting board and let it rest for 5-10 minutes. This crucial step allows the juices to redistribute, so every slice remains moist. Tent loosely with foil to keep it warm.

Slice the chicken against the grain into ½-inch thick pieces. Arrange on a platter with the 0.5 whole red onion, thinly sliced, the 0.5 cup Kalata olive, and a generous sprinkle of 0.25 cup fresh parsley. The olives add a briny contrast, while the parsley brings a fresh, bright finish to the dish.

Troubleshooting Perfect Results

Dry Chicken Prevention

If your chicken turns out dry, the most likely culprit is overcooking. Use a meat thermometer and pull it from the oven at exactly 165°F internal temperature. I keep a ThermoWorks Instant Read in my kitchen drawer for this exact purpose. 🌡️

Marinade Separation

If your marinade separates, don’t worry—it’s natural for olive oil and lemon juice to separate. Just whisk it vigorously before adding the chicken. For better emulsion, slowly drizzle the oil while whisking the lemon juice and herbs together first.

Uneven Cooking

Uneven thickness leads to some pieces cooking faster than others. Always pound the chicken to ¾-inch thickness using a meat mallet or rolling pin. I place the breasts between sheets of plastic wrap to prevent splattering. This ensures even cooking throughout.

Herb Flavor Too Strong

If the herb flavor overpowers, you may have used too much dried oregano. Remember dried herbs are 3 times more potent than fresh. Start with 1 tbsp dried instead of the ¼ cup fresh called for, then adjust to taste.

Bland Chicken

For more flavor impact, extend the marinating time to overnight. Also, don’t shake off all the marinade before roasting—leave a thin coating on the chicken. I also sprinkle an extra ½ tsp kosher salt on each breast just before it goes into the oven. 💡

Sticking Problems

To prevent sticking, use a wire rack on your baking sheet and lightly oil it. If you don’t have a rack, turn the chicken halfway through cooking. The high heat of 400°F can cause the sugars in the marinade to caramelize and stick to the pan.
