Pork Loin

Gratin Dauphinois

Seasonal Vegetables

Method

Pork Loin

  1. 1

    Prep and season pork

    Pat the pork loin dry with paper towels. In a small bowl, mix salt, pepper, and chopped rosemary. Rub the pork with olive oil, then rub the seasoning all over the meat. If using, spread Dijon mustard on all sides.

  2. 2

    Sear the pork

    Heat a large ovenproof skillet over medium-high heat with a little olive oil. Sear the pork on all sides until deeply browned, about 6-8 minutes total.

  3. 3

    Roast the pork

    Transfer the pork to a roasting pan. Roast in a preheated 180°C (350°F) oven until an instant-read thermometer reads 145-150°F (63-66°C) at the thickest part, about 60-75 minutes. Baste once midway if desired.

  4. 4

    Rest and pan sauce

    Remove from oven and tent with foil. Rest at least 10-15 minutes. Optional pan sauce: deglaze the skillet with a splash of wine or broth, simmer to reduce, whisk in a knob of butter and any juices from the roast.

Gratin Dauphinois

  1. 5

    Prepare dish and preheat

    Preheat oven to 180°C (350°F). Rub a gratin dish with a cut clove of garlic.

  2. 6

    Layer potatoes

    Spread a thin layer of potato slices in the dish. Season lightly with salt, pepper, and a pinch of nutmeg. Pour a portion of the cream-milk mixture over the layer.

  3. 7

    Finish the layers

    Layer the remaining potatoes, pouring over the rest of the cream-milk mixture. Dot with butter and top with the grated Gruyère cheese.

  4. 8

    Bake

    Bake until potatoes are tender and the top is golden and bubbling, about 60-75 minutes. If the top browns too quickly, loosely cover with foil.

Seasonal Vegetables

  1. 9

    Prep vegetables

    Wash, trim, and cut carrots, Brussels sprouts, and asparagus as indicated.

  2. 10

    Roast vegetables

    Toss with olive oil, salt, and pepper. Spread on a baking sheet in a single layer and roast in the oven alongside the gratin or pork during the last 25-30 minutes, until tender and caramelized.
