Vietnamese-Style Spaghetti Squash “Noodle” Bowls with Skirt Steak

This vibrant Vietnamese-style spaghetti squash noodle bowl offers a fresh, grain-free alternative to traditional rice vermicelli dishes. By roasting the spaghetti squash until tender, you create delicate vegetable strands that perfectly absorb the zesty flavours of lime, ginger, and fish sauce. Combined with flash-seared skirt steak and a punchy jalapeño dressing, it is a dish that balances savoury depth with a bright, herbaceous crunch.

As a high-protein main course, this recipe is ideal for those seeking a lighter dinner that doesn't compromise on satisfaction. The combination of cooling cucumber, mung bean sprouts, and fragrant coriander brings an authentic Southeast Asian street-food feel to your kitchen. It is an excellent choice for meal prep, as both the squash and the marinated beef can be prepared in advance for a quick midweek assembly.

Ingredients for Vietnamese-Style Spaghetti Squash “Noodle” Bowls with Skirt Steak

  • 1 medium spaghetti squash (2–1.1kg), halved lengthwise, seeded

  • 1 1/2 teaspoons kosher salt

  • 60ml fish sauce

  • 1 tablespoon brown sugar

  • 1 tablespoon finely grated fresh ginger

  • 2 garlic cloves, finely grated

  • 120ml fresh lime juice, divided

  • 450g skirt steak, cut crosswise into 4-inch sections

  • 1 medium jalapeño, stemmed, seeded, finely chopped

  • 45ml toasted sesame oil

  • 1 tablespoon neutral vegetable oil

  • 1/2 cos heart, coarsely chopped (about 600g )

  • 1 medium carrot, peeled, sliced into 3" matchsticks

  • 1 mini or Persian cucumber, cut in half lengthwise, thinly sliced

  • 1/2 cup mung bean sprouts (about 60g )

  • 2 spring onions, thinly sliced

  • 1/4 cup coriander leaves

  • 1/4 cup roasted salted peanuts, coarsely chopped

Preheat oven to 191°C. Line a rimmed baking sheet with parchment paper.

Sprinkle each half of squash with 1/4 teaspoons salt, then place cut side down on prepared baking sheet. Bake until interior of squash is fork-tender, 40–50 minutes. Let cool.

Meanwhile, whisk fish sauce, brown sugar, ginger, garlic, 2 tablespoons lime juice, and 1/2 teaspoons salt in a large bowl. Transfer 45ml fish sauce mixture to a shallow wide bowl. Add steak and turn to coat. Let sit at room temperature at least 30 minutes.

Add jalapeño, sesame oil, and remaining 90ml lime juice to remaining fish sauce mixture in large bowl and stir to combine.

Using a fork, scrape squash crosswise to pull strands from shells into a large bowl; discard shells. Toss squash with 4 tablespoons jalapeño sauce and remaining 1/2 teaspoons salt.

Heat vegetable oil in a large heavy skillet over high; pat steak dry. Working in batches if needed, sear steak until browned, about 3 minutes per side for medium-rare. Let rest 5 minutes, then thinly slice lengthwise against the grain.

Divide squash among bowls. Toss lettuce, carrot, cucumber, and bean sprouts in remaining jalapeño sauce, then arrange over squash. Add steak to bowls, then top with spring onions, coriander, and peanuts.

Squash can be cooked 2 days ahead. Let cool completely, then store in an airtight container and chill. Steak can be marinated 1 day ahead. Store in a resealable plastic bag and chill.
