Ingredients
For the Steak
- 2 ribeye or sirloin steaks, about 8 ounces each
- 1 tablespoon olive oil
- 1 tablespoon unsalted butter
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1 teaspoon dried thyme
- 1 teaspoon fresh rosemary, chopped
- Salt, to taste
- Black pepper, to taste
- Coarse sea salt, for garnish
For the Mashed Potatoes
- 1 1/2 pounds potatoes, peeled and cubed
- 3 tablespoons unsalted butter
- 1/3 cup warm milk
- 2 tablespoons heavy cream
- Salt, to taste
- Black pepper, to taste
For the Roasted Vegetables
- 8 baby potatoes, halved
- 2 medium carrots, cut into sticks
- 1 tablespoon olive oil
- 1/2 teaspoon garlic powder
- 1/2 teaspoon dried thyme
- Salt, to taste
- Black pepper, to taste
Instructions
Start with the mashed potatoes. Place the cubed potatoes in a pot of salted water and bring them to a boil. Let them cook for 15 to 18 minutes, until they are fork-tender and easy to mash.
While those cook, preheat your oven to 425°F (220°C). Toss the baby potatoes and carrot sticks with olive oil, garlic powder, thyme, salt, and black pepper. Spread them out on a baking sheet so they have room to roast instead of steam.
Slide the vegetables into the oven and roast for 25 to 30 minutes. Turn them once halfway through so they get golden on all sides and tender in the middle.
Once the boiling potatoes are done, drain them well. Mash them with the butter, warm milk, and heavy cream until smooth and creamy. Season with salt and black pepper to taste, then cover and keep warm.
Now turn to the steaks. Pat them dry with paper towels so they sear properly. Rub them with olive oil, then season with garlic powder, onion powder, thyme, rosemary, salt, and black pepper. Make sure both sides are well coated.
Heat a grill pan or heavy skillet over medium-high heat. Once it is hot, add the steaks. Sear them for 3 to 5 minutes per side, depending on their thickness and how you like them cooked. You want that deep brown crust and those lovely grill marks or caramelized edges.
During the last minute of cooking, add the butter to the pan. As it melts, spoon it over the steaks again and again. This gives them extra richness and brings out the flavor of the herbs in the most delicious way.
Transfer the steaks to a plate and let them rest for 5 minutes. That short rest makes a big difference and keeps the meat juicy.
To serve, spoon the creamy mashed potatoes onto each plate. Add a generous pile of roasted vegetables alongside, then place the steak next to everything. Finish with a pinch of coarse sea salt and, if you like, a little extra rosemary or thyme on top.
Presentation
This dish looks especially beautiful when the mashed potatoes are swooshed gently onto the plate and the steak is set right beside them. Stack the roasted vegetables in a relaxed pile for a cozy, rustic feel.
A sprinkle of coarse sea salt over the steak just before serving adds texture and makes it look extra inviting. A little fresh rosemary or thyme on top gives the plate a finished touch. If you want to make it feel restaurant-worthy, spoon a bit of the buttery pan juices over the steak right before it goes to the table.
