Preheat oven to 400°F (200°C). Line a large sheet pan with foil.
Melt butter in a saucepan over medium heat. Add honey, garlic, salt, and pepper. Bring to a boil, then reduce heat and simmer 5–6 minutes. Set aside.
Pound chicken breasts to even thickness. Cut potatoes into evenly sized pieces.
Arrange chicken and potatoes on the sheet pan. Drizzle with oil and sprinkle with garlic powder, pepper, paprika, and steakhouse seasoning.
Pour honey garlic sauce over the chicken.
Bake for 25–30 minutes, until chicken is cooked through and potatoes are fork-tender.
Remove from oven and let rest a few minutes before serving.
