Steak and Arugula Crispy Potato Slippers
Thinly sliced rare hanger steak, roasted beet wedges, and peppery arugula piled high on crispy, skin-on roasted potato slippers over a creamy, grainy mustard aioli, finished with red pepper flakes.
Ingredients
The Potato Slippers
- 1 large Russet potato, scrubbed clean (leave the skin on)
- 2 tbsp olive oil
- tbsp salt and freshly cracked black pepper
For the Steak
- ½ lb hanger steak (or flank/skirt), brought to room temperature
- 1 tbsp olive oil
- salt and black pepper to taste
For the Mustard Spread
- 2 tbsp mayonnaise
- 1 tbsp grainy Dijon mustard
- ½ tsp lemon juice
For the Salad
- 1 cup baby arugula
- 1 cooked beet, cut into bite-sized wedges
- 1 tsp extra virgin olive oil
- crushed red pepper flakes (for final dusting)
Directions
Roast the Potatoes
-
Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
-
Slice the potato: Slice the potato lengthwise into thick, uniform planks (about 1/3-inch thick). To get the ridges seen in the photo, you can use a wavy/waffle mandoline blade or gently score the surface crosswise with a knife.
-
3. Season: Pat the potato planks completely dry with a paper towel. Rub both sides generously with olive oil, salt, and pepper.
-
Roast: Bake for 25–30 minutes, flipping halfway through, until the edges are deeply browned, slightly blistered, and crispy.
Sear and Thinly Slice the Steak
-
Heat the pan: Get a cast-iron skillet smoking hot over high heat.
-
Season: Pat the hanger steak dry and season heavily with salt and coarse pepper.
-
Sear: Add 1 tablespoon of olive oil to the pan and sear the steak for 3–4 minutes per side for a beautiful rare-to-medium-rare center.
-
Rest and shave: Let it rest on a board for 5–10 minutes, then shave it into paper-thin ribbons cutting against the grain.
Mix the Mustard Cream & Toss Salad
-
The Spread: In a small bowl, whisk together the mayonnaise, grainy mustard, lemon juice, and garlic powder. Set aside.
-
The Salad: In a separate bowl, lightly toss the baby arugula and beet wedges with 1 teaspoon of olive oil and a tiny pinch of salt. Gently fold in the thin steak ribbons so they catch a bit of the oil.
Assemble the Plate
-
Place the hot, crispy potato slippers side-by-side on your serving plate.
-
Spread the base: Slather a generous layer of the mustard cream spread directly across the top surface of each potato slipper.
-
Pile the toppings: Group bundles of the steak, beets, and arugula together and pile them evenly along the length of each potato slipper.
-
Garnish: Dust the top of the slippers and the surrounding plate with crushed red pepper flakes.
