Roasting the garlic brings out a mellow, slightly sweet flavor that blends perfectly into the silky pan sauce. The sauce captures all the flavor left behind from searing the steak, creating a luxurious drizzle you’ll want to spoon over everything on the plate. Chive-studded mashed Yukon Gold potatoes add comforting richness, while oven-roasted green beans bring balance and texture to the meal.

This dish comes together in about 40 minutes and feels elegant enough for a special occasion, yet approachable enough for a confident weeknight cook.

How It Comes Together
First, garlic is roasted in foil until soft and fragrant while green beans roast alongside it until tender and lightly browned. Meanwhile, Yukon Gold potatoes are boiled and mashed with sour cream until smooth and creamy.
The ribeye steak is seasoned simply and seared in a hot pan to develop a flavorful crust. After resting the steak, the same pan is used to create the sauce—mashed roasted garlic, beef demi-glace, butter, and a splash of water simmer together to form a rich, glossy finish.
Finally, the steak is sliced and served with mashed potatoes and green beans, all topped with the savory garlic sauce and finished with fresh chives.
Serving Notes
- Let the steak rest before slicing to keep it juicy
- Slice against the grain for the most tender bites
- Spoon extra sauce over both the steak and potatoes for maximum flavor
