Few meals capture indulgence and comfort quite like a perfectly seared ribeye steak paired with creamy mashed potatoes. It’s a dish that feels luxurious yet approachable, combining a golden-brown crusted steak with fluffy potatoes and the richness of garlic butter melting over the top. Whether it’s a romantic dinner, a special family meal, or simply a night when you want to treat yourself, this recipe guarantees a restaurant-quality experience at home.
Why This Recipe Works
The magic of this dish comes from balance and technique. Ribeye is one of the most flavorful cuts of beef, thanks to its marbling, which melts into the meat as it cooks, creating tenderness and juiciness. When seared correctly in a hot skillet, ribeye develops a deep crust while staying pink and succulent inside.
The garlic butter plays its part by infusing the steak with richness and aroma, while velvety mashed potatoes create the perfect counterpart to the bold beef flavors. Put together, it’s a classic steakhouse-style plate that’s comforting, hearty, and surprisingly simple to achieve in your own kitchen.
Ingredients You’ll Need
For the Ribeye and Garlic Butter
- 2 bone-in ribeye steaks (about 1 to 1.5 inches thick)
- Salt and freshly ground black pepper, to taste
- 2 tablespoons olive oil
- 4 tablespoons unsalted butter
- 4 garlic cloves, smashed
- Optional: a few sprigs of fresh rosemary or thyme
For the Mashed Potatoes
- 2 pounds potatoes (Yukon Gold or Russet work best)
- 4 tablespoons butter
- ½ cup whole milk or heavy cream, warmed
- Salt and black pepper, to taste
- Optional: roasted garlic or sour cream for extra creaminess
Step-by-Step Instructions
Step 1: Prepare the Mashed Potatoes
- Peel and cube the potatoes into even chunks to ensure they cook evenly.
- Place them in a large pot, cover with cold water, and add a generous pinch of salt.
- Bring to a boil and cook until fork-tender, about 15–20 minutes.
- Drain the potatoes thoroughly to avoid watery mash.
- Mash with butter and warm milk or cream until smooth. Season with salt and pepper. For ultra-creamy potatoes, use a potato ricer or hand mixer.
Step 2: Bring Steaks to Room Temperature
Before searing, let the ribeyes rest at room temperature for about 30 minutes. This step ensures even cooking and a consistent crust.
Step 3: Season Generously
Pat the steaks dry with paper towels. Generously season both sides with salt and freshly cracked black pepper. This simple seasoning enhances the natural beef flavor.
Step 4: Sear the Ribeye Steaks
- Heat a heavy-bottomed skillet, preferably cast iron, over medium-high heat until very hot. Add olive oil.
- Lay the steaks in the skillet carefully, away from you to avoid oil splatter.
- Sear without moving for 3–4 minutes on each side for medium-rare, flipping only once.
- In the final minute of cooking, reduce heat slightly and add butter, smashed garlic cloves, and optional rosemary or thyme.
- Tilt the skillet and spoon the melted garlic butter over the steaks to baste them with flavor.
Step 5: Rest the Steaks
Transfer steaks to a plate or cutting board and let them rest for 5–10 minutes. Resting allows the juices to redistribute, preventing them from running out when sliced.
Step 6: Serve and Enjoy
Plate the ribeye steaks with a generous portion of mashed potatoes on the side. Drizzle pan juices or extra garlic butter over both for maximum indulgence.
Tips for Ribeye Perfection
-
Use a meat thermometer: Ensure accuracy with these internal temperatures:
- Rare: 120–125°F (49–52°C)
- Medium Rare: 130–135°F (54–57°C)
- Medium: 140–145°F (60–63°C)
- Medium Well: 150–155°F (65–68°C)
- Well Done: 160°F (71°C) and above (not recommended for ribeye)
- Avoid overcrowding the pan: If your skillet isn’t large enough, cook steaks one at a time. Overcrowding traps steam, preventing a proper sear.
- Don’t skip the resting time: Cutting too soon makes the steak lose its juices. Be patient.
- Butter basting is essential: This step layers on flavor and keeps the meat juicy.
Serving Suggestions
This dish is already a complete meal, but you can elevate it with a few sides and pairings:
- Vegetables: Sautéed green beans, crispy Brussels sprouts, or roasted carrots complement the richness of the steak.
- Fresh Garnish: Sprinkle fresh parsley, chives, or thyme over the dish for color and freshness.
- Sauce Additions: A splash of Worcestershire sauce or balsamic reduction in the butter adds extra depth.
- Wine Pairing: A bold red wine like Cabernet Sauvignon, Malbec, or Syrah pairs beautifully with ribeye.
Variations to Try
- Spicy Kick: Add chili flakes or smoked paprika to the steak before searing.
- Herb-Infused: Swap rosemary for sage or thyme for a different aroma.
- Dairy-Free: Use plant-based butter and almond or oat milk for mashed potatoes.
- Loaded Potatoes: Stir in sour cream, shredded cheese, or roasted garlic for extra indulgence.
Storing and Reheating Leftovers
- Refrigeration: Store leftover steak and mashed potatoes in separate airtight containers for up to 3 days.
- Reheating Steak: Warm gently in a skillet over low heat with a little beef broth or butter to keep it moist.
- Reheating Potatoes: Stir in a splash of milk or cream and reheat over low heat until creamy again.
- Freezing: Mashed potatoes freeze well, but ribeye is best enjoyed fresh.
FAQs About Seared Ribeye with Garlic Butter
Can I use boneless ribeye instead of bone-in?
Yes. Boneless ribeye cooks slightly faster, but it delivers the same rich flavor and tenderness.
What’s the best skillet for searing ribeye?
A cast iron skillet is ideal because it holds high heat and creates a deep, flavorful crust.
How do I know when the steak is ready to flip?
When the steak naturally releases from the pan and develops a dark crust, it’s ready to turn.
Can I make this recipe with other cuts of beef?
Yes. New York strip, filet mignon, or sirloin can be prepared similarly, though cooking times may vary.
What can I substitute for heavy cream in mashed potatoes?
Whole milk, half-and-half, or plant-based milk can be used. For extra richness, add sour cream.
Can I cook the steak in the oven instead?
Yes. After searing each side for 2 minutes in the skillet, transfer to a preheated oven at 400°F (200°C) until the desired doneness is reached.
