Sheet Pan Dinner: Hanger Steak with Mushrooms and Carrots

Ingredients

Instructions

  1. Heat the oven to 475°F with a large rimmed sheet pan on the upper rack — a screaming-hot pan is what keeps the carrots from going pale and limp.
  2. Toss the carrots with 2 tablespoons melted tallow and 1/2 teaspoon salt, then spread on the hot pan and roast 10 minutes.
  3. Push the carrots to one side, add the mushrooms, smashed garlic, thyme sprigs, and remaining 1 tablespoon tallow to the empty side, and roast 12 minutes more, tossing everything once, until the mushrooms are browned and the carrots are tender with charred edges.
  4. While the vegetables finish, season the steaks all over with the coriander, remaining 1 teaspoon salt, and pepper. Sear in a cast-iron skillet over the highest heat 2-3 minutes per side, to 120-125°F for medium-rare.
  5. Rest the steaks on a cutting board 5 minutes; hanger steak turns tough and gray if you cut it hot.
  6. Pull the sheet pan out, discard the thyme stems, and toss the vegetables with the red wine vinegar and cold butter right on the pan until glossy.
  7. Carve the steaks thick, against the grain, and pile on top of the vegetables with the pan juices.

Why this recipe works

Tips for making this recipe well

Cut carrots on the bias

Half-inch diagonal coins put more flat surface against the hot pan than round coins. More contact means more browning in the same 10 minutes. Rounds also roll away when you toss the pan.

Sear hard, check the side

Cast iron on the highest heat, 2-3 minutes per side, targets 120-125°F for medium-rare. Check through the side of the steak with an instant-read thermometer. Hanger steak's loose grain needs a dark crust to balance it.

Rest while you finish

Five minutes on the board, and the recipe is blunt about why: hanger steak turns tough and gray when cut hot. Toss the vegetables with vinegar and butter during that window. Resting and finishing share the clock.

Carve thick, against the grain

Hanger steak's grain runs one long, clear direction. Slicing across it keeps the pieces tender; slicing with it turns the plate stringy. Cut thick slices too, since thin ones cool before they reach the table.

Pull the thyme stems

The sprigs perfume the mushrooms and carrots through the roast and come out before the butter toss. Their work is done by then. Fishing stems first keeps the glaze glossy and the pan clean.

Serving suggestions

Pile the carved steak over the vegetables and pour every drop of the pan glaze on top. At 12.3 net carbs, with the carrots carrying most of that number, this plate stands alone. If you want a companion, arugula with a mustard vinaigrette sits well next to the tallow and butter. Open a bottle for the table, since the red wine vinegar in the pan sauce points that direction already. Slice at the table and let everyone see the medium-rare center before it's gone.

Storage and meal prep

Refrigerate leftovers in a covered container for 3 to 4 days. The carrots and mushrooms hold their shape better than most roasted vegetables, and the steak is good cold, sliced thin over greens. To reheat, give the vegetables a few minutes in a 400°F oven and the steak one quick turn in a hot skillet so the center stays pink. Freezing works for 2 to 3 months, though the carrots soften noticeably after thawing. This one is at its best on day one, so size the batch to your table.

Variations worth trying

Frequently asked questions

Why preheat the empty sheet pan?

Vegetables dropped onto a 475°F surface brown on contact instead of warming slowly in their own moisture. Cold-pan starts are why roasted carrots so often turn out pale and limp. The recipe heats the empty pan on the upper rack first for exactly this reason.

What if I don't have beef tallow?

Use another high-heat fat for the roasting and searing; butter burns at 475°F. Save the cold butter for the finish, where it belongs. The tablespoon tossed at the end needs to be cold, not the cooking fat.

How do I hit medium-rare?

The recipe targets 120-125°F after 2-3 minutes per side on the highest heat. Check through the side with an instant-read thermometer. The 5-minute rest nudges the temperature up a few degrees while the juices settle.

Can I roast the vegetables longer?

By about 5 minutes, if you want deeper char, but toss them at the halfway point as written. Past that the mushrooms shrink and the carrot edges dry instead of caramelizing. The butter-vinegar toss is timed for when they still have snap.

Why vinegar and butter at the very end?

Roasted vegetables land flat without acid, and the red wine vinegar cuts the three tablespoons of tallow. Cold butter melts in the pan's residual heat into a glaze that coats everything. Added earlier, both cook off instead of coating.
