Hanger Steak with Shallots and Jerusalem Artichokes

Preparation

1. Roasted Shallots

   Step 1

   Preheat oven to 350°. Heat butter in a large ovenproof skillet over medium heat. Cook shallots, tossing occasionally, until golden brown, 8–10 minutes. Add pepper, 1 teaspoon salt, and 2 tablespoons vinegar and toss. Roast shallots in oven, checking after 10 minutes and shaking pan to turn and adding a splash or so of water if butter is burning, until tender, 10–20 minutes.

   Step 2

   Meanwhile, whisk oil, chile, and remaining 1/4 cup vinegar in a large bowl; season with salt (vinaigrette will separate as it sits).

   Step 3

   When shallots are done cooking, whisk vinaigrette, add shallots, and toss gently.

2. Purée:

   Step 4

   Cook Jerusalem artichokes in a large saucepan of boiling, generously salted water until tender, 10–12 minutes. Drain; return to saucepan. Cook over medium heat, tossing, until dry, about 2 minutes. Remove from heat, add cream and butter, and stir to combine.

   Step 5

   Purée in a blender. With motor running, gradually add oil and blend until emulsified; season with salt. Strain through a fine-mesh sieve into a large bowl; discard solids.

3. Steak and Assembly:

   Step 6

   Prepare grill for medium-high heat. Season steaks with salt and grill, turning occasionally, until lightly charred and an instant-read thermometer registers 130° for medium-rare, 8–10 minutes. Transfer to a cutting board. Squeeze lemons over and drizzle with oil; season with pepper. Let rest 5–10 minutes before slicing.

   Step 7

   Spoon purée onto plates and place steak around. Top with shallots, leaving vinaigrette in pan. Toss herbs and fennel fronds in vinaigrette; season with salt. Top steak with salad and drizzle with oil.
