Preheat oven to 350 degrees F (175 degrees C).
Add Bone-In Chicken Leg (4), Lemon (1), Fresh Rosemary (4 sprig), Garlic (3 clove), and Baby Potato (2 pound) to a sheet pan or baking dish. Drizzle with Olive Oil (to taste), Salt and Pepper (to taste). Toss to coat. Make sure the chicken is well seasoned on both sides.
Cook for 45 minutes. Remove the tray from the oven. Gently squeeze the roasted lemon wedges over everything in the pan.
Cook another 15 minutes until the chicken is cooked through and the potatoes are toasty.
Remove from oven, serve and enjoy!
