Preheat your oven to 180°C (350°F) so it’s fully ready for even cooking. Lightly grease a baking dish with a small amount of oil or cooking spray, then place the chicken breasts inside in a single layer, leaving a little space between each piece so they cook evenly.

In a mixing bowl, combine Greek yogurt, olive oil, freshly squeezed lemon juice, lemon pepper seasoning, garlic powder, dried parsley, salt, and black pepper. Use a whisk or spoon to mix everything thoroughly until you get a smooth, creamy sauce with evenly distributed seasoning.

Spoon the prepared sauce over the chicken breasts and spread it evenly across the top and sides using the back of a spoon. Make sure each piece is fully coated, as this helps keep the chicken moist and infuses it with flavor during baking.

Place the baking dish in the preheated oven and bake for about 25–30 minutes. The chicken should be fully cooked through, tender, and juicy. You can check doneness by ensuring the internal temperature reaches 75°C (165°F) or that the juices run clear.

If you’d like to add cheese, sprinkle it over the chicken during the last 5 minutes of baking. Return the dish to the oven just long enough for the cheese to melt and become slightly golden and bubbly on top.

Remove the dish from the oven and let the chicken rest for 3–5 minutes before serving. This allows the juices to redistribute, keeping the chicken tender and flavorful. Serve warm for the best taste and texture.
