Instructions

  1. Adjust oven racks to the middle and top positions. Preheat the oven to 450°F. Wash and dry all produce. Halve, peel and finely chop the shallot. Slice the potatoes into ¼-inch-thick rounds (no need to peel).
  2. Lightly oil a baking sheet. In a large bowl, combine the potatoes, 4 tablespoons olive oil, garlic powder and generous pinches of salt and pepper. Toss until the potatoes are completely coated. Arrange the potatoes on the prepared baking sheet in clusters (about 6 slightly overlapping slices each). Roast on the middle rack for 10 minutes.
  3. Meanwhile, toss the green beans on a second baking sheet with a drizzle of olive oil, salt and pepper. After the potatoes have roasted for 10 minutes, remove them from the oven and sprinkle with Parmesan cheese. Return the potatoes to the middle rack and place the green beans on the top rack. Roast until the potatoes are tender and the cheese is lightly browned and the green beans are tender, about 12-15 minutes.
  4. While the green beans roast, pat the steak dry with paper towels and season all over with salt and pepper. Heat a large drizzle of vegetable oil in a large pan over medium-high heat. Add the steak and cook to your desired doneness, 4-6 minutes per side. Turn off the heat, transfer the steak to a cutting board and let it rest. Wipe out the pan.
  5. Heat a drizzle of olive oil in the same pan over medium heat. Add the shallot and cook, stirring, until softened, 1-2 minutes. Pour in the sherry vinegar and simmer until reduced by half, 15-30 seconds. Stir in ⅓ cup water and the beef stock concentrates. Simmer until the sauce thickens, 2-3 minutes. Turn off the heat. Stir in the sour cream and 2 tablespoons butter. Season with salt and pepper.
  6. Slice the steak against the grain. Divide the potato clusters, green beans and steak among plates. Spoon the sauce over the steak and serve.

Recipe Tips

For the best sear, make sure the steak is patted very dry before seasoning.

Let the steak rest for at least 5 minutes before slicing to keep it juicy.

If you don’t have sherry vinegar, you can substitute with red wine vinegar mixed with a pinch of sugar.

FAQ

Can I use a different cut of steak?

Yes, you can substitute the sirloin with ribeye, strip steak or filet mignon. Adjust cooking time based on thickness.

Can I make the potato clusters ahead of time?

The potato clusters are best served fresh from the oven, but you can reheat them in a 400°F oven for a few minutes to crisp them up.

What can I use instead of sour cream in the sauce?

You can substitute the sour cream with heavy cream or crème fraîche for a similar richness.
