Butternut Squash Steaks with Brown Butter–Sage Sauce

This elegant vegetarian dish transforms the humble autumn squash into a sophisticated centrepiece. By pan-searing thick slices of the squash neck, you achieve a caramelised exterior and a tender, melting middle that rivals any traditional roast. The addition of crispy sage and toasted brown butter lends a deep, savoury flavour that perfectly balances the natural sweetness of the vegetable.

Ideal for a midweek treat or a meat-free Sunday lunch, these butternut squash steaks are remarkably simple to prepare. The garlic and lemon juice provide a bright finish to the rich sauce, ensuring the dish feels light yet satisfying. Serve alongside some nutty quinoa or a crisp green salad for a balanced and wholesome homemade meal.

Ingredients for Butternut Squash Steaks with Brown Butter–Sage Sauce

  • 1 large butternut squash (about 1.4kg .), preferably one with a long thick neck

  • 1 tablespoon extra-virgin olive oil

  • 2 tablespoons unsalted butter, cut into pieces

  • 6 sage leaves

  • 2 garlic cloves, crushed

  • 1 tablespoon fresh lemon juice

  • Kosher salt, freshly ground pepper

Cut the neck off of squash; reserve base for another use. Trim the stem off the neck then peel. Resting neck on cut base, cut in half lengthwise, creating two lobes. Trim off outer rounded side of each piece to create two 3/4"-thick steaks (about 170g per steak); reserve trimmed off sides for another use.

Heat oil in a large heavy skillet over medium. Cook squash steaks, turning every 3 minutes, until deeply browned on both sides and fork-tender, about 15 minutes. Add butter, sage, and garlic to skillet, tilt pan toward you so that butter pools on one side, and use a large spoon to continually baste steaks with butter. Cook, basting, until butter is no longer bubbling, smells nutty, and is beginning to brown, about 1 minute. Remove from heat and stir in lemon juice; season with salt and pepper.

Transfer squash steaks to plates and spoon sauce over.
