I first made this sheet pan steak dinner for a busy weeknight, amazed at how easy it was to put together a complete, comforting meal with hardly any dishes to wash at the end. My family raved about the tender steak and garlicky potatoes & it quickly became a staple dinner in our rotation.
Ingredients
- Boneless sirloin steaks: 4 (6 oz / 170 g)

Instructions
- Prep:
- Preheat oven to 425°F (220°C). Line a large sheet pan with parchment paper or foil.
- Boil Potatoes:
- Place potatoes and garlic in a large saucepan. Cover with water and add a generous pinch of salt. Bring to a boil, then simmer for 12–15 minutes until fork-tender. Drain well.
- Mash Potatoes:
- Return potatoes and garlic to the pot. Add butter, cream, salt, and pepper. Mash until smooth and creamy. Set aside, covered to keep warm.
- Season Steak:
- While potatoes cook, pat steaks dry. Rub both sides with olive oil, salt, pepper, paprika, and thyme. Let rest at room temperature.
- Prep Green Beans:
- Toss green beans with olive oil, salt, and pepper. Spread evenly on one side of the prepared sheet pan.
- Arrange Pan:
- Mound mashed potatoes on the other side of the pan, forming 4 separate piles. Lay steaks in the remaining space on the pan.
- Roast:
- Roast for 12–15 minutes, flipping steaks halfway through, until desired doneness (130°F/54°C for medium-rare).
- Brown Steaks (Optional):
- If needed, broil for 2 minutes to brown the steaks.
- Finish & Serve:
- Remove from oven. Let steaks rest for 5 minutes. Sprinkle with parsley before serving.
