• 3 cloves garlic, minced
• 2 tbsp butter
• 1 tbsp olive oil

Instructions:

1. Preheat the oven to 375°F (190°C).

   • Stir in the grated Parmesan cheese.
6. Assemble the casserole:

   • Pour the creamy onion sauce over the chicken.
   • Top with shredded mozzarella cheese.
7. Bake:
   • Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.
