Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large bowl, combine the ground chicken, ricotta cheese, panko breadcrumbs, egg, Parmesan cheese, lemon zest, oregano, garlic powder, salt, and pepper. Mix gently until just combined. Do not overmix.
Roll the mixture into meatballs, about 1.5 inches in diameter. Place them on the prepared baking sheet.
Bake for 20-25 minutes, or until browned and cooked through.
While the meatballs are baking, prepare the sauce. Heat the olive oil in a skillet over medium heat. Add the minced garlic and cook until fragrant, about 1 minute.
Pour in the chicken broth and lemon juice. Bring to a simmer and cook for 5 minutes, scraping up any browned bits from the bottom of the pan.
Stir in the butter until melted and the sauce is slightly thickened.
Add the baked meatballs to the skillet with the sauce. Gently toss to coat.
Garnish with fresh parsley and serve immediately.
Notes
These meatballs are great served with orzo, pasta, or a side salad.
