Pasta & Base

  • 400g (14 oz) spaghetti (whole wheat or regular)
  • 2 tbsp olive oil

Aromatics & Vegetables

  • 1 large onion, finely diced
  • 3 cloves garlic, minced
  • 1 large carrot, finely diced
  • 1 celery stalk, finely diced
  • 1 red bell pepper, diced
  • 200g (7 oz) mushrooms, sliced (cremini or portobello work best)

Sauce Elements

  • 1 can (400g / 14 oz) crushed tomatoes
  • 2 tbsp tomato paste
  • ½ tsp sugar (optional, to balance acidity)
  • 1 tsp dried oregano
  • 1 tsp dried basil (or a handful of fresh, torn at the end)
  • Salt and pepper to taste

Finishing Touches

  • Fresh parsley, chopped
  • Grated parmesan or plant-based cheese
  • Extra olive oil for drizzling

Cooking Instructions

  1. Prep The Vegetables

    • Chop everything before you start cooking – it’s much easier to keep the process smooth without scrambling to dice onions while your garlic burns.
  2. Cook The Pasta

    • Bring a large pot of salted water to a boil.
    • Cook spaghetti according to package instructions until al dente.
    • Reserve ½ cup pasta water before draining.
  3. Build The Flavor Base

    • Heat olive oil in a large skillet over medium heat.
    • Add onion, carrot, and celery. Cook for 5-7 minutes until softened.
    • Add garlic and red pepper, sauté for another 2 minutes.
  4. Add Mushrooms & Herbs

    • Toss in sliced mushrooms, letting them cook until golden and reduced (about 5 minutes).
    • Sprinkle in oregano and basil, stirring to coat vegetables with seasoning.
  5. Make The Sauce

    • Stir in tomato paste, cooking for 1 minute to deepen flavor.
    • Pour in crushed tomatoes, sugar (if using), salt, and pepper.
    • Lower heat, cover, and simmer for 10-15 minutes.
  6. Combine Pasta & Sauce

    • Add drained spaghetti to the skillet.
    • Toss together, adding reserved pasta water a splash at a time for a silkier sauce.
  7. Finish & Serve

    • Top with parsley, parmesan, and a light drizzle of olive oil.
    • Serve hot and enjoy the applause from your taste buds.

Ingredient Science Spotlight

  • Onions & Garlic – The backbone of savory flavor. They release sulfur compounds when cut, which mellow into sweetness when cooked.
  • Carrot & Celery – Classic soffritto vegetables that create a balanced sweetness and depth, softening the acidity of tomatoes.
  • Mushrooms – Nature’s umami bombs. They contain glutamates, giving you that rich, meaty flavor without actual meat.
  • Tomato Paste – Not just for color. Cooking it briefly caramelizes natural sugars and intensifies the sauce’s body.
  • Reserved Pasta Water – The starch in it binds sauce to pasta, creating a silky, restaurant-quality texture.

Expert Tips

  • Don’t rush the onions. A few extra minutes here makes all the difference in sweetness and flavor depth.
  • Salt in stages. Add a little with each ingredient to enhance natural flavors instead of dumping it all at the end.
  • Use fresh herbs if possible. Dried are fine for simmering, but fresh basil at the end is transformative.
  • Sauce tastes better the next day. Make extra for effortless lunches.

Recipe Variations

  • Spicy Kick – Add red pepper flakes with the garlic.
  • Creamy Tomato Twist – Stir in ¼ cup cream or coconut milk just before serving.
  • Protein Boost – Add cooked lentils or chickpeas to the sauce.
  • Green Power – Toss in spinach or kale during the last 2 minutes of cooking.

Final Words

This spaghetti isn’t about ’making do’ without meat – it’s about redefining what satisfying pasta can be. By layering vegetables, aromatics, and umami-rich ingredients, you get depth, texture, and comfort in every bite.

It’s simple enough to whip up after work but sophisticated enough for guests who think vegetarian food is “just salad”. You’ll prove them wrong – deliciously.
