Ingredients
Instructions
- Preheat the oven to 425°F (220°C). Wash and dry all produce. Cut the potatoes in half, then into ½-inch-thick wedges. Trim the woody ends from the asparagus and cut into 1-inch pieces. Pat the steak dry with paper towels and season generously with salt and pepper. Let it sit at room temperature.
- On one side of a baking sheet, toss the potato wedges with a drizzle of olive oil, salt and pepper. Peel the garlic clove and place it in the center of a small piece of foil. Drizzle with olive oil and season with salt and pepper. Wrap into a packet and place on the same baking sheet. Roast on the top rack for 18 minutes.
- After 18 minutes, remove the sheet from the oven. Add the asparagus to the empty side of the sheet, drizzle with olive oil, salt and pepper and toss to coat. Return to the oven and roast until the potatoes are browned and tender and the asparagus is lightly browned, about 10-12 minutes more.
- While the vegetables roast, prepare the aromatics. Trim and thinly slice the scallions, separating the white and green parts. Halve, peel and mince the red onion until you have 2 tablespoons (or more if desired).
- Pat the steak dry again. Heat a drizzle of olive oil in a large skillet over medium-high heat. Add the steak and cook until browned on the first side, 3-6 minutes. Flip the steak, reduce the heat to medium and add 1 teaspoon Herbes de Provence and 2 tablespoons butter to the pan. Tilt the pan slightly and use a spoon to baste the steak with the melted butter continuously until the steak reaches your desired doneness, 6-9 minutes more. Transfer the steak to a cutting board to rest, leaving the butter in the pan.
- Return the skillet to medium-high heat. Add the minced onion and cook, stirring, until softened, 3-4 minutes. Add the scallion whites and cook for 1-2 minutes. Stir in the beef stock concentrate and ¼ cup water. Bring to a simmer and cook until the sauce thickens slightly, 2-3 minutes. Remove from heat.
- Carefully unwrap the roasted garlic and mash it with a fork. In a small bowl, combine the mayonnaise with as much mashed garlic as you like. Season with salt and pepper.
- Slice the rested steak against the grain. Divide the steak, roasted potatoes and asparagus among plates. Stir any juices from the cutting board into the pan sauce. Drizzle the sauce over the steak and garnish with scallion greens. Serve the garlic aioli on the side.
Recipe Tips
For the best sear, pat the steak dry before cooking and let it come to room temperature.
Basting the steak with butter and Herbes de Provence adds incredible flavor and keeps the meat moist.
Let the steak rest for at least 5 minutes before slicing to retain its juices.
FAQ
