This Classic Ribeye Steak and Creamy Mashed Potatoes platter represents the ultimate steakhouse dinner experience prepared right at home. A thick-cut, well-marbled ribeye steak is pan-seared to medium-rare perfection in a cast-iron skillet, basted with aromatic garlic and rosemary butter to form a caramelized, savory crust. Served alongside silky, velvety mashed potatoes filled with a pool of rich brown gravy and vibrant roasted vegetables, this comforting meal is pure culinary indulgence.
Detailed Ingredients
For the Ribeye Steak:
- 1 thick-cut bone-in or boneless ribeye steak (approx. 14–16 oz, 1.5 inches thick)
- 1.5 tsp kosher salt
- 1 tsp freshly cracked black pepper
- 1.5 tbsp high-smoke point oil (avocado or canola oil)
- 3 tbsp unsalted butter
- 4 cloves garlic, smashed
- 3 sprigs fresh rosemary
- 3 sprigs fresh thyme
For the Creamy Mashed Potatoes & Gravy:
- 1.5 lbs (680g) Yukon Gold potatoes, peeled and quartered
- 1/3 cup heavy cream, warmed
- 4 tbsp unsalted butter, softened
- 1/2 tsp garlic powder
- Salt and white pepper, to taste
- 1 cup rich beef or veal gravy (warm)
For the Roasted Vegetables:
- 1 cup broccoli florets
- 1 cup baby carrots, halved lengthwise
- 1/2 cup cherry tomatoes on the vine
- 1.5 tbsp olive oil
- Salt and black pepper, to taste
Step-by-Step Instructions
- Prep and Roast Vegetables: Preheat oven to 400°F (200°C). Toss broccoli florets, baby carrots, and cherry tomatoes in olive oil, salt, and pepper on a baking sheet. Roast for 20–25 minutes until tender and caramelized at the edges.
- Make the Mashed Potatoes: Place quartered Yukon Gold potatoes in a pot of cold, heavily salted water. Bring to a boil and cook for 15–20 minutes until fork-tender. Drain well and return to the warm pot for 1 minute to evaporate excess moisture. Mash thoroughly using a potato ricer or masher. Stir in warmed heavy cream, softened butter, garlic powder, salt, and pepper until velvety smooth. Keep warm.
- Season the Steak: Dry the ribeye thoroughly with paper towels (moisture prevents a good sear). Season generously on all sides with kosher salt and cracked black pepper at least 15 minutes before cooking.
- Pan-Sear and Baste: Heat a heavy cast-iron skillet over high heat until smoking. Add 1.5 tablespoons of avocado oil. Carefully lay the steak in the skillet away from you. Sear for 2 minutes without moving it to form a deep crust, then flip.
- Butter Baste: Reduce heat to medium. Add 3 tablespoons of butter, smashed garlic, rosemary, and thyme to the skillet. Tilt the pan slightly toward you and use a large spoon to continuously baste the foaming hot herb butter over the steak for 2–3 minutes until the internal temperature reaches 130°F (54°C) for medium-rare.
- Rest, Slice, and Serve: Transfer the steak to a cutting board and let it rest for 8–10 minutes to lock in juices. Slice across the grain into thick pieces. Plate alongside a generous mound of creamy mashed potatoes with a well carved in the center filled with hot brown gravy, and arrange the roasted vegetables on the side.
Tips, Variations, and Storage Notes
- Tips: Yukon Gold potatoes have a natural buttery flavor and creamy texture that yields the smoothest mash without getting gummy.
- Variations: Swap ribeye for New York strip or tenderloin cutlets. Add roasted garlic cloves directly into the mashed potatoes for extra aroma.
- Storage: Store cooked steak and mashed potatoes in separate airtight containers in the refrigerator for up to 3 days. Reheat the steak gently in a 250°F (120°C) oven to retain tenderness without overcooking.
Pairings
- Beverages: Sparkling cranberry-pomegranate mocktail with fresh sage, ice-cold sparkling water with lime, or non-alcoholic red grape spritzer.
- Sides: Caesar salad with parmesan crisp croutons, or sautéed garlic mushrooms.
