    Heat the oven to 200 °C / 400 °F and line a baking tray with parchment.

  2. 2

    Carefully cut the spaghetti squash in half lengthwise and scoop out the seeds.

  3. 3

    Brush the cut sides with 1 tsp of the olive oil and sprinkle with 1/4 tsp of the salt and the black pepper.

  4. 4

    Place the halves cut side down on the tray and roast for 40-45 minutes, until the flesh is tender when pierced with a fork.

  5. 5

    Meanwhile, warm the remaining olive oil in a saucepan over medium heat.

  6. 6

    Add the onion and cook for 5-6 minutes, stirring, until soft and translucent.

  7. 7

    Stir in the garlic, oregano and red pepper flakes and cook for 1 minute until fragrant.

    Pour in the crushed tomatoes, add the remaining salt and bring to a gentle simmer.

Swaps, storage and make-ahead

Swaps

  • Stir a can of drained white beans or a cup of cooked lentils into the sauce for a heartier vegan meal.
  • Use grated Parmesan instead of nutritional yeast if you don't need it to be vegan or dairy-free. Traditional Parmesan is made with animal rennet, so choose a vegetarian hard cheese to keep it vegetarian.
  • Swap the crushed tomatoes for no-salt-added crushed tomatoes and season to taste at the end.
  • Use 1 tsp dried basil in the sauce if fresh basil is hard to find, adding it with the oregano.

Storage

Refrigerate leftovers within 2 hours, ideally keeping the squash and sauce in separate airtight containers, and eat within 3 to 4 days, reheating until steaming hot. The sauce freezes well for up to 3 months, but the squash strands turn watery when frozen, so it is best not to freeze them.

Make ahead

Make the marinara up to 4 days ahead and keep it in the fridge, or freeze it. You can also roast and shred the squash a day or two ahead, then reheat it in a pan or microwave until steaming before topping with hot sauce and fresh basil.
