Instructions

Step 1: In a large bowl, combine 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 6 bone-in chicken thighs and turn to coat well. Marinate for at least 30 minutes at room temperature.
Step 2: Preheat the oven to 400°F. Arrange the marinated chicken thighs on a baking sheet lined with foil, skin side up. Roast for 35-40 minutes until skin is crispy and internal temperature reaches 165°F.
Step 3: While the chicken roasts, prepare tzatziki by mixing 1 cup Greek yogurt with 1/2 grated and drained cucumber, 1 tbsp chopped fresh dill, 1 tsp white wine vinegar, and a pinch of salt. Stir until combined and refrigerate until serving.
Step 4: Serve the roasted chicken thighs hot with a generous dollop of tzatziki sauce on the side.
