Instructions

1. Step 1: In a large bowl, whisk together 1/4 cup fresh lemon juice, 3 tbsp olive oil, 2 tsp dried oregano, 4 minced garlic cloves, 1 tsp salt, and 1/2 tsp black pepper. Add 1.5 lbs boneless skinless chicken thighs and toss to coat thoroughly. Cover and marinate in the refrigerator for at least 1 hour, preferably up to 4 hours.
2. Step 2: Preheat the oven to 400°F (200°C). Arrange the marinated chicken thighs on a rimmed baking sheet lined with parchment paper, spacing evenly. Roast for 25-30 minutes until the chicken is cooked through and juices run clear, with edges starting to brown.
3. Step 3: While the chicken roasts, prepare the tzatziki by combining 1 cup Greek yogurt, 1/2 cup finely grated and well-drained cucumber, 2 tbsp chopped fresh dill, 1 tbsp white vinegar, 1 minced garlic clove, and 1/4 tsp salt in a bowl. Stir well and refrigerate until ready to serve.
4. Step 4: Remove the chicken from the oven and let rest for 5 minutes. Serve hot with the chilled tzatziki sauce alongside warm pita bread or a Greek salad.
