Equipment

  • Large Pot (for pasta)
  • Large Skillet
  • Blender (standard or immersion - only if making the creamy version)
  • Knife
  • Cutting Board
  • Colander
  • Measuring Cups
  • Measuring Spoons

Ingredients
  

  • 1 pound 450g pasta (your choice - whole wheat, spelt, GF recommended)
  • 3-4 medium zucchini approx 1.5 lbs / 680g, chopped or sliced
  • 1/2 cup 70g raw, unsalted cashews, soaked 2+ hours & drained (for optional creamy sauce)
  • 2 tablespoons ghee or coconut oil / light olive oil
  • 1 tablespoon fresh lemon juice
  • 1/2 cup loosely packed fresh basil leaves chopped (plus extra for garnish)
  • 1 teaspoon Himalayan pink salt or sea salt, plus more for pasta water & taste
  • 1/4 teaspoon freshly ground black pepper or to taste
  • Water for boiling pasta
  • 1 cup reserved pasta cooking water
  • Optional: Lemon zest for garnish
  • Optional: Toasted pumpkin or sunflower seeds for garnish

Instructions
 

  • Prepare Cashews (If Using): Ensure cashews are soaked (min. 2 hours), then drain well.
  • Cook Pasta: Boil pasta in generously salted water until al dente according to package directions. Important: Reserve about 1 cup of pasta water before draining. Drain pasta and set aside.
  • Prepare Zucchini: Wash, trim, and chop zucchini into roughly 1/2-inch pieces/slices.
  • Sauté Zucchini: Heat ghee/oil in a large skillet over medium heat. Add zucchini, 1/2 tsp salt, and 1/4 tsp pepper. Cook, stirring occasionally, until tender (about 8-10 minutes). Avoid significant browning.
  • Make Creamy Sauce (Optional): Transfer about 2/3 of the cooked zucchini to a blender. Add drained cashews, 1 tbsp lemon juice, and 1/2 cup reserved pasta water. Blend until very smooth. Add more pasta water (1 tbsp at a time) if needed to reach desired consistency. Taste and adjust salt.
  • Combine Sauce & Pasta: Pour blended sauce (if made) back into the skillet with remaining zucchini. If not blending, proceed with all sautéed zucchini in the skillet. Add cooked pasta. Toss gently over low heat until coated. Add more pasta water if dry. Simmer 1-2 minutes.
  • Add Fresh Herbs: Turn off heat. Stir in chopped fresh basil.
  • Serve: Taste and adjust seasoning (salt, pepper). Serve immediately, garnished with extra basil, lemon zest, or toasted seeds if desired.

NOTES:

  • Use fresh, firm, medium zucchini. Avoid overly large ones.
  • Al dente pasta is key to prevent mushiness.
  • Don't skip reserving the starchy pasta water; it's vital for the sauce texture.
  • For a lighter creamy sauce (nut-free): Skip cashews, blend 1/2 the cooked zucchini with 1/2 cup pasta water.
  • Other creaminess option: 1/2 cup full-fat coconut milk instead of cashews.
  • Storage: Best fresh. Refrigerate leftovers up to 2 days. Reheat gently on stovetop with a splash of water.
