Ingredients
Instructions
- Preheat the oven to 425°F. Wash and dry the produce. Peel the potatoes and cut them into 1/2-inch cubes.
- Place the potatoes in a medium pot with a large pinch of salt and enough water to cover by 1 inch. Bring to a boil and cook until the potatoes are easily pierced with a knife, 12 to 15 minutes. Drain, then return the potatoes to the pot.
- While the potatoes cook, crush the tricolor peppercorns with a mallet or the bottom of a heavy pan until coarsely ground. Finely chop the parsley. Peel, halve and chop the shallot.
- Toss the green beans on a baking sheet with a drizzle of vegetable oil and a pinch each of salt and pepper. Roast until tender, 12 to 15 minutes.
- Heat a drizzle of vegetable oil in a large pan over medium-high heat. Pat the rib-eye dry with paper towels, then season all over with salt and pepper.
- Add the steak to the hot pan and cook to your desired doneness, 3 to 6 minutes per side. Transfer the steak to a plate to rest. Loosely cover with aluminum foil if you want to keep it warm.
- Reduce the heat under the pan to medium-low and add another drizzle of vegetable oil. Add the shallot and cook, tossing, until softened, 1 to 2 minutes.
- Stir in 1/4 teaspoon crushed peppercorns, the beef demi-glace and 1/2 cup water. Bring to a boil, then reduce the heat and simmer until slightly reduced, 2 to 3 minutes.
- Remove the sauce from the heat. Stir in the butter and half of the sour cream until the butter melts and the sauce is smooth. Season with salt and pepper to taste.
- Add the remaining sour cream and 1/2 teaspoon truffle oil to the drained potatoes. Mash with a potato masher or fork until smooth. Season with salt and pepper, adjusting the truffle oil to taste if desired.
- Slice the rested steak thinly against the grain. Toss the roasted green beans with the sliced almonds.
- Divide the truffle mashed potatoes, almond green beans and sliced steak between plates. Spoon the peppercorn sauce over the steak and potatoes, then garnish with parsley.
Recipe Tips
Patting the steak dry before seasoning helps it sear instead of steam.
Use more or less crushed peppercorn depending on how bold you want the sauce.
Let the rib-eye rest before slicing so the juices settle back into the meat.
A splash of milk can be added to the potatoes if you want a looser, creamier mash.
Truffle oil is potent, so start with the listed amount and adjust to taste.
