Prepare the Chicken:
Heat butter and olive oil in a skillet over medium heat.
Season the chicken pieces with salt and pepper, then sauté with garlic until golden brown and fully cooked (about 7-10 minutes).
Set aside and keep warm.
Make the Parmesan Cream Sauce:
In the same skillet, add heavy cream, Parmesan, garlic powder, onion powder, and Italian seasoning.
Let the sauce simmer for 5 minutes until it thickens.
Season with salt and pepper to taste.
Prepare the Cheesy Roasted Potatoes:
Preheat the oven to 400°F (200°C).
Toss the cubed potatoes with olive oil, garlic powder, parsley, salt, and pepper.
Roast the potatoes on a baking sheet for 25-30 minutes or until golden and crispy.
Sprinkle with cheddar and Parmesan cheese, then return to the oven for another 5 minutes until the cheese is melted.
Assemble:
Pour the Parmesan cream sauce over the chicken bites and garnish with fresh parsley.
Serve alongside the cheesy roasted potatoes.
