Ingredients You’ll Need
For the Steak
- 2 ribeye, sirloin, or New York strip steaks (about 1 inch thick)
- Salt and freshly ground black pepper, to taste
- 2 tablespoons olive oil
- 3 tablespoons butter
- 4 garlic cloves, smashed
- 3 sprigs fresh thyme or rosemary
For the Garlic Mashed Potatoes
- 2 pounds (900g) Yukon Gold or Russet potatoes, peeled and cubed
- 4 cloves garlic, peeled
- 4 tablespoons butter
- ½ cup whole milk (or heavy cream for extra richness)
- 2 tablespoons sour cream (optional for tang)
- Salt and pepper, to taste
- Fresh parsley, chopped (for garnish)
Step-by-Step Instructions
Step 1: Prepare the Potatoes
Peel and cube your potatoes evenly—this helps them cook uniformly. Place them in a large pot of cold water and add a generous pinch of salt. Bring to a boil and cook for 15–20 minutes, or until tender when pierced with a fork.
Add the garlic cloves to the boiling water halfway through cooking to soften and infuse flavor.
Step 2: Drain and Mash
Once the potatoes and garlic are tender, drain them thoroughly. Return them to the pot to steam for 1–2 minutes—this removes excess moisture and prevents a watery mash.
Mash using a potato masher or ricer until smooth. Add butter, warm milk, and sour cream (if using). Stir until creamy and fluffy. Season with salt and pepper to taste. Keep warm while you prepare the steak.
Step 3: Bring the Steak to Room Temperature
Before cooking, remove the steaks from the refrigerator for about 30 minutes. This ensures even cooking throughout. Pat dry with paper towels to remove any moisture—dry surfaces sear better.
Season both sides generously with salt and pepper.
Step 4: Sear the Steak
Heat a large cast-iron skillet or heavy-bottomed pan over medium-high heat until hot. Add the olive oil, then carefully place the steaks in the pan.
Sear for 3–4 minutes on the first side without moving them—this allows a crust to form. Flip the steaks and add butter, garlic cloves, and thyme/rosemary to the pan.
As the butter melts, tilt the pan slightly and use a spoon to baste the steaks with the fragrant garlic-herb butter. Cook for another 3–4 minutes for medium-rare (adjust depending on your preferred doneness).
Use a meat thermometer if possible:
- 125°F (52°C) for rare
- 135°F (57°C) for medium-rare
- 145°F (63°C) for medium
Step 5: Rest the Steak
Once cooked, transfer the steaks to a plate and tent loosely with foil. Let them rest for 5–10 minutes to allow the juices to redistribute, keeping the meat tender and flavorful.
Step 6: Plate and Serve
Spoon a generous portion of garlic mashed potatoes onto each plate. Slice the steak against the grain and arrange it beside the potatoes. Spoon a bit of the pan’s garlic butter over the steak for extra flavor.
Garnish with fresh parsley or a sprinkle of flaky sea salt for the finishing touch.
Chef’s Tips for Perfect Results
- Choose marbled steak: Ribeye offers the most flavor, but sirloin or strip steak also works beautifully.
- Don’t overcrowd the pan: Cook steaks one or two at a time for an even sear.
- Use warm milk: Cold liquid can make mashed potatoes gluey.
- Mash gently: Over-mixing can result in dense potatoes; stop once creamy.
- Let it rest: Resting is crucial for juicy steak—don’t skip it.
Flavor Variations
- Garlic Herb Butter Steak: Mix softened butter with minced garlic, parsley, and lemon zest, and melt it over the steak before serving.
- Truffle Mashed Potatoes: Add a drizzle of truffle oil or sprinkle of truffle salt for a luxurious touch.
- Creamy Mushroom Sauce: Pour a mushroom cream sauce over the steak for a bistro-style upgrade.
- Spicy Twist: Add a pinch of smoked paprika or chili flakes to the butter for heat.
