Equipment

  • large pot
  • skillet
  • Box grater or food processor
  • Blender (optional)
  • Airtight container (for storage)

Ingredients
  

  • 12 oz dry pasta any shape
  • 2.5 lb zucchini ends trimmed
  • ¾ cup extra-virgin olive oil
  • 1 cup sweet onion finely diced
  • 1 pinch crushed red pepper flakes optional
  • 1.5 tbsp garlic minced
  • 1 tsp kosher salt
  • 1 tsp freshly ground black pepper
  • 2 tbsp fresh basil chopped
  • 2 tbsp fresh oregano chopped
  • 2 tbsp fresh mint chopped
  • 1 cup heavy cream or half-and-half
  • ¾ cup Romano cheese finely grated, or Parmesan

Notes

  • Pasta Water Reserve 1 cup of starchy pasta water before draining pasta. Essential for binding sauce to noodles; add gradually to adjust consistency.

Optional Add-ins

  • White beans stir in
  • Sautéed mushrooms stir in
  • Shredded chicken stir in
  • Pesto a spoonful

Substitutions

  • Yellow squash can replace zucchini
  • Half-and-half use instead of heavy cream
  • Milk and cornstarch slurry substitute for cream
  • Full-fat canned coconut milk dairy-free substitute for heavy cream
  • Nutritional yeast dairy-free substitute for cheese

Garnish

  • Fresh herbs remaining chopped

Instructions
 

  • Boil salted water and cook pasta until al dente. Reserve 1 cup of pasta water before draining. Toss drained pasta with a little olive oil.
  • Halve zucchini, remove seeds if mature, and shred. Heat olive oil in a skillet over medium heat. Sauté onion until soft (approx. 3 minutes), then add garlic and red pepper flakes (if using) and cook until fragrant (approx. 1 minute).
  • Add shredded zucchini, salt, pepper, and half the herbs to the skillet. Increase heat to a simmer, cover, and cook on medium-low for 12–15 minutes until zucchini collapses, stirring occasionally.
  • Remove lid. Pour in cream and stir in the remaining herbs. Warm until the sauce slightly thickens.
  • Stir in grated cheese until melted and smooth. Whisk in reserved pasta water a few tablespoons at a time if the sauce is too thick.
  • Combine the pasta and sauce in the skillet, or spoon the sauce over plated pasta. Garnish with the remaining fresh herbs.

Notes

  • For a silkier sauce, puree half of the cooked zucchini mixture before adding cream. Scoop out seeds from large zucchini to prevent a watery texture.
  • For a lighter version, use half-and-half or substitute cream with milk and a cornstarch slurry. For dairy-free, use full-fat canned coconut milk and nutritional yeast.
  • Add delicate herbs like basil and mint at the end to preserve their freshness. Add a squeeze of lemon or extra salt if the sauce tastes flat.
  • Sauce can be stored in an airtight container in the fridge for up to 4 days, or freeze sauce only (not pasta) for up to 3 months. Reheat gently, adding liquid if thickened.
