How To Make Spaghetti Squash Bolognese

Roast Spaghetti Squash

Four step collage for roasting spaghetti squash.
  • Preheat the oven to 400°F. Line a baking sheet with parchment.
  • Carefully cut the squash in half lengthwise. If cutting is tough, microwave the whole squash for 3 to 4 minutes to soften the skin. Scoop out the seeds.
  • Rub the cut sides with olive oil, then season with salt and pepper. Place halves cut-side down on the lined sheet.
  • Roast 35 to 45 minutes until a fork slides in easily and the strands pull apart. Pull earlier if your oven runs hot to avoid mushy strands.
  • Let sit for 5 minutes. Use a fork to scrape the flesh into “noodles.”

Make Hearty Bolognese Sauce

Four step collage showing how to make bolognese sauce.
  • In a large skillet, warm 1 to 2 tablespoons olive oil over medium heat.
  • Add diced onion and cook until softened, about 5 minutes. Add garlic and cook 30 seconds. Add the chopped zucchini and carrot and continue cooking, stirring to keep from sticking, for an additional 5 minutes.
  • Crumble in ground beef. Season with salt and pepper. Cook until browned and caramelized, about 7 to 8 minutes.
  • Stir in tomato paste and cook 1 to 2 minutes to caramelize and deepen the sauce.
  • Pour in crushed tomatoes. Bring to a gentle simmer and cook 15 to 20 minutes, stirring now and then, until thick and glossy.
  • Stir in chopped fresh basil. Taste and adjust salt and pepper.

Plate and Serve

  • Divide squash strands among 4 bowls.
  • Spoon the hot bolognese over the top.
  • Finish with grated Parmesan and more basil if you are not doing Whole30.
  • For dairy-free, drizzle extra-virgin olive oil and nutritional yeast.
  • Add red pepper flakes for gentle heat.
  • Taste and salt right before serving.

Tips

  • Always read labels on tomato paste and crushed tomatoes to avoid hidden sugars.
  • No fresh basil? Use 1 teaspoon dried Italian seasoning or 1/2 teaspoon dried basil.
  • Spread spaghetti squash strands on a clean towel or paper towels for a minute to drain. This keeps bowls from getting watery.
  • Faster sauce: Use a quality no sugar added marinara in place of crushed tomatoes and tomato paste on busy nights.

How To Store

  • Store cooked squash strands and sauce in separate airtight containers. Refrigerate up to 4 days.
  • Reheat the sauce on the stove over medium heat until hot and thick.
  • Warm squash gently in a dry skillet over low to medium heat to steam off extra moisture. Stir a few times until heated through.
  • Freeze the bolognese sauce up to 3 months. Thaw in the fridge, then simmer to revive flavor. Do not freeze cooked squash, it turns soft and watery after thawing.
  • Assemble bowls right before eating for the best texture.
