In a large mixing bowl, combine ground chicken, ranch seasoning mix, egg, breadcrumbs, and garlic powder. Stir gently until just blended; avoid overmixing to keep the meat tender.

Using your hands, shape the mixture into golf ball-sized portions. Place the balls on a parchment-lined baking sheet, leaving some space between each for even cooking.

Preheat your oven to 400°F (200°C). Lightly spray the tops with olive oil and bake in the preheated oven for 18-22 minutes, or until they turn a lovely golden brown.

Once they are baked, remove the chicken bombs from the oven and add mozzarella on top of each one. Broil for 1-2 minutes until the cheese is bubbly and starts to turn golden.

Sprinkle chopped parsley over the melted cheese and serve warm alongside your favorite dipping sauces, or with sides like mashed potatoes or fresh veggies.
