Charred Steak and Broccolini with Cheese Sauce

This charred steak and broccolini with cheese sauce is a sophisticated yet simple dish that proves diabetes-friendly cooking can be truly indulgent. By searing the steaks in their own fat before finishing them in the oven, you achieve a professional crust and a succulent centre. The earthy, slightly bitter notes of the roasted broccolini provide the perfect counterpoint to the rich, peppery beef.

Served with a velvety sauce made from Gruyère and a hint of nutmeg, this high-protein, low-carbohydrate meal is an excellent choice for a midweek treat or a Saturday night dinner. Using cream cheese ensures the sauce remains stable and smooth without the need for a flour-based roux, keeping the dish naturally lighter and suitable for those monitoring their starch intake.

Ingredients for Charred Steak and Broccolini with Cheese Sauce

  • 2 (1 1/2"–2" thick) boneless New York strip steaks

  • 1 teaspoon freshly ground black pepper

  • 2 1/4 teaspoons kosher salt, divided

  • 2 bunches broccolini (about 450g total), trimmed, halved lengthwise

  • 1 tablespoon extra-virgin olive oil

  • 90g coarsely grated Gruyère (about 350ml )

  • 90g cream cheese, cut into pieces

  • 180ml whole milk

  • 1/4 teaspoons freshly grated or ground nutmeg

  • Large pinch of cayenne pepper

  • Flaky sea salt

Preheat oven to 232°C. Season steaks all over with pepper and 1 1/2 teaspoons kosher salt. Let sit 10 minutes.

Meanwhile, toss broccolini, oil, and 1/2 teaspoons kosher salt on a rimmed baking sheet to combine. Spread out in a single layer and set aside.

Using tongs if needed, hold both steaks together fat cap side down in a large ovenproof skillet, then set over high heat. Cook until pan is coated in fat, about 4 minutes. Lay steaks flat and continue to sear until deeply browned, about 3 minutes per side. Transfer skillet to oven and roast steaks until an instant-read thermometer inserted into the thickest part registers 49°C for medium-rare, 6–8 minutes. Transfer to a cutting board and let rest 10 minutes before slicing.

While steaks are resting, roast reserved broccolini until crisp-tender and lightly charred, about 10 minutes.

Heat cheese, cream cheese, milk, nutmeg, cayenne, and remaining 1/4 teaspoons kosher salt in a medium saucepan over medium, whisking constantly, until a smooth sauce forms, about 5 minutes.

Divide sauce among plates. Top with broccolini and steaks; sprinkle with sea salt.
