Creating High-Protein Creamy Garlic Cheesy Chicken Potatoes is a straightforward process when you follow these steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Potatoes: Boil a pot of salted water. Add the diced potatoes and cook until tender, about 10-15 minutes. Drain and set aside.
3. Cook the Chicken: In a large skillet, heat olive oil over medium heat. Add the cubed chicken and season with salt, pepper, onion powder, garlic powder, and paprika. Cook until the chicken is browned and cooked through, about 5-7 minutes.
4. Make the Sauce: Add the minced garlic to the skillet and sauté for an additional 1-2 minutes until fragrant. Pour in the heavy cream and stir to combine. Allow the sauce to simmer for 3-5 minutes until slightly thickened.
5. Combine Ingredients: In a large mixing bowl, combine the cooked potatoes and chicken mixture. Stir gently to coat the potatoes in the creamy garlic sauce.
6. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish. Spread it evenly.
7. Add Cheese: Sprinkle the shredded cheddar cheese generously over the top of the potato and chicken mixture.
8. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown.
9. Garnish: Remove from the oven and let it cool for about 10 minutes. Garnish with fresh parsley if desired.
