Mustard-Crusted Pork with Carrots and Lentils

Preparation

1. Step 1

   Preheat oven to 425°F with rack in middle.

   Step 2

   Toss carrots with 2 tablespoons oil and 1/4 teaspoon each of salt and pepper in a shallow baking pan and roast while preparing pork.

   Step 3

   Pat pork dry and sprinkle with 1/2 teaspoon salt. Heat 1 tablespoon oil in a 12-inch heavy skillet over medium-high heat until it shimmers, then brown pork all over, about 3 minutes total.

   Step 4

   Put pork on a work surface and brush with 1 tablespoon mustard. Stir together bread crumbs and 1/2 tablespoon oil, then press onto mustard on pork to form a crust.

   Step 5

   Transfer pork to pan with carrots and roast until carrots are browned and tender and an instant-read thermometer inserted into center of meat registers 140 to 145°F, 15 to 22 minutes. Let pork stand 5 minutes; keep carrots warm, covered (or continue roasting if needed).

   Step 6

   While pork roasts, heat remaining 2 tablespoons oil with garlic and thyme in a small saucepan until fragrant, about 1 minute. Stir in lentils, broth, and remaining tablespoon mustard and cook until heated through. Season with salt and pepper and discard thyme. Serve pork with carrots and lentils.
