Garlic Butter Steak and Potatoes Skillet is a bold, savory one-pan meal with juicy steak bites, golden potatoes, and a rich garlic herb butter sauce. Fast, satisfying, and perfect for any night.
1½ lbs sirloin or ribeye steak, cut into cubes
1½ lbs baby potatoes, halved
1 tbsp olive oil (plus more if needed)
3 tbsp unsalted butter
4–5 garlic cloves, minced
1 tsp chopped fresh rosemary
1 tsp chopped fresh thyme
Salt and pepper, to taste
Optional: chopped parsley, lemon juice
Boil potatoes 6–7 min until just tender. Drain and pat dry.
Heat 1 tbsp oil in skillet. Sear potatoes cut-side down 5–7 min until golden. Remove.
Pat steak dry and season. Sear in batches 2–3 min per side. Remove.
Reduce heat. Add butter, garlic, rosemary, and thyme. Sauté 30 sec.
Return steak and potatoes to skillet. Toss to coat in garlic butter.
Cook 1–2 min until heated through. Garnish and serve hot.
Use a cast-iron skillet for best sear. Don’t overcook garlic. Add lemon or broth to deglaze if needed.
