In a large skillet, melt the butter over medium heat.
Add the chicken pieces to the skillet and season with garlic powder, onion powder, smoked paprika, salt, and pepper. Cook for about 5-7 minutes, stirring occasionally, until the chicken is cooked through and golden brown.
Reduce the heat to low and pour in the heavy cream, stirring to combine. Let it simmer for 2-3 minutes until the sauce thickens slightly.
Sprinkle the shredded cheddar cheese over the chicken and cover the skillet with a lid. Allow the cheese to melt for about 2-3 minutes.
Once the cheese is melted, remove the skillet from heat and garnish with diced green onions and chopped parsley.
Serve immediately with crusty bread or over rice for a complete meal.
