Pin A hearty, all-in-one meal featuring juicy steak and creamy garlic mashed potatoes roasted together on a single sheet pan for maximum flavor and minimal cleanup.

Instructions

- 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.
- Prep Steaks:
- While potatoes cook, pat steaks dry. Rub both sides with olive oil, salt, pepper, paprika, and thyme. Let rest at room temperature.

- Arrange Pan:
- Mound mashed potatoes on the other side of the pan, forming 4 separate piles.
- Add Steaks:
