Preheat the oven to 400°F (200°C). Pat the chicken dry and season both sides with salt, pepper, and dried oregano.
Heat the olive oil in a skillet over medium-high heat. When hot, sear the chicken breasts 4 minutes per side until golden brown.
Transfer the seared chicken to a baking dish in a single layer.
In a mixing bowl, whisk together the melted butter, minced garlic, chicken broth, and fresh lemon juice.
Pour the lemon-garlic butter mixture over the chicken, then place the dish in the preheated oven.
Bake for 25–30 minutes, or until the internal temperature of the chicken reaches 165°F (74°C).
Remove from the oven, baste the chicken with the pan juices, sprinkle with chopped parsley, and serve with lemon wedges.
