Let’s dive into making this comforting dish. I promise it’s as straightforward as it is delicious.

1. Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish.
2. In a large skillet, heat olive oil over medium-high heat. Season the chicken pieces with salt and pepper, then brown them in the skillet for about 5-6 minutes. Transfer the chicken to a plate and set aside.
3. In the same skillet, melt the butter over medium heat. Add the minced garlic and cook until fragrant, about 1 minute.
4. Stir in the heavy cream, chicken broth, and dried thyme. Let the mixture simmer for 2-3 minutes until slightly thickened.
5. Place the diced potatoes in the prepared baking dish. Pour the creamy garlic sauce over the potatoes, ensuring they are well-coated.
6. Add the browned chicken pieces on top of the potatoes. Sprinkle the shredded cheddar cheese over everything.
7. Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes.
8. Remove the foil and bake for an additional 15 minutes, or until the potatoes are tender and the cheese is bubbly and golden brown.
9. Let the casserole rest for a few minutes before serving. This is a great time to share some stories or laughter around the table, just like we did during those Sunday dinners growing up.
