Preheat the oven to 350°F (175°C).

In a large skillet, melt a tablespoon of butter over medium heat. Add 1 pound of cubed chicken breast, seasoning with salt and pepper, and cook until the chicken is no longer pink, about 5–7 minutes.

In the same skillet, reduce the heat to low and add 1 cup of heavy cream, 8 oz. of cream cheese, and 2 minced garlic cloves. Whisk until smooth and creamy, about 3–5 minutes.

In a greased baking dish, layer the cooked chicken, then scatter veggies if using, and pour the creamy sauce over. Top with 1 cup of shredded cheddar cheese.

Bake for 25–30 minutes until bubbly and golden brown.

Let it cool for 5–10 minutes, then serve and enjoy.
