What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 400 g spaghetti
  • 400 g canned crushed tomatoes
  • 2 whole medium carrots peeled and chopped
  • 1 whole medium zucchini roughly chopped
  • 1 whole small onion diced
  • 2 cloves garlic

Step by step instructions

Step 1: Soften the Vegetables

Heat a drizzle of olive oil in a large pot over medium heat and cook the onion, carrots, zucchini, and garlic for 10 minutes until completely softened and beginning to turn golden.

Step 2: Add Tomatoes and Simmer

Pour in the crushed tomatoes, season with salt and a pinch of sugar, and simmer the sauce on low heat for 15 minutes to allow all the flavors to meld together.

Step 3: Blend Until Smooth

Use an immersion blender directly in the pot or carefully transfer to a countertop blender to blend the sauce until it is completely smooth with no visible vegetable pieces.

Step 4: Cook Pasta and Combine

Cook spaghetti in a large pot of salted boiling water according to package directions. Drain and toss with the blended sauce, serving with grated parmesan on top.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • zucchini → cauliflower florets or spinach
  • canned crushed tomatoes → passata or blended fresh tomatoes

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Not cooking the vegetables long enough before blending which leaves a raw veggie flavor in the sauce
  • Blending a hot sauce in a countertop blender without leaving the lid slightly open which can cause a dangerous steam explosion
