Ingredients

  • 12 oz Dry pasta (penne or fettuccine) (Choose gluten‑free if needed)
  • 1 cup Raw cashews (Unsalted, raw; soak for 15 minutes)
  • 1 cup Raw walnuts (Unsalted; toasted lightly in pan)
  • 1 cup Broccoli stems (Trimmed and cut into ½‑inch cubes)
  • 4 pieces Garlic cloves (Minced)
  • 1 piece Jalapeño (Finely diced; optional for heat)
  • 2 tbsp Vegan butter (Unsalted)
  • 1 cup Coconut milk (full‑fat, canned) (Shake well before opening)
  • 1 cup Vegetable stock (Low‑sodium; keep extra on hand for deglazing)
  • 1 large Avocado (Diced; keep refrigerated until use)
  • 2 tbsp Nutritional yeast (Adds cheesy flavor; optional)
  • 1 tsp Salt
  • ½ tsp Black pepper (Freshly ground)
  • 1 tbsp Olive oil (For sautéing walnuts)
  • 1 tsp Lemon juice (Optional brightening)

Instructions

  1. Prep Ingredients

    Trim broccoli stems and cut into ½‑inch cubes. Mince garlic, dice jalapeño, and measure out all nuts and liquids.

    Time: PT10M

  2. Soak Cashews

    Place cashews in a bowl, cover with hot water and let sit for 15 minutes. Drain before blending.

    Time: PT15M

  3. Cook Pasta

    Bring a large pot of salted water to a rolling boil (212°F). Add pasta and cook al dente according to package, usually 10‑12 minutes. Reserve ½ cup pasta water, then drain.

    Time: PT12M

    Temperature: 212°F

  4. Process Walnut Mixture

    In the food processor, combine walnuts, half the minced garlic, diced jalapeño, ½ tsp salt, and ¼ tsp pepper. Pulse until the mixture resembles coarse crumbs, not a paste.

    Time: PT5M

  5. Sauté Walnut Crumble

    Heat skillet over medium heat, add olive oil, then the walnut crumb. Sauté 3‑4 minutes until fragrant. Deglaze with ¼ cup vegetable stock, scraping the browned bits.

    Time: PT5M

  6. Blend Cashew Cream

    Drain soaked cashews and place in the processor with coconut milk, remaining vegetable stock, nutritional yeast, lemon juice (if using), and a pinch of salt. Blend until completely smooth.

    Time: PT5M

  7. Make the Sauce

    In the same skillet, melt vegan butter over medium‑low heat. Pour in the cashew cream, stir, and bring to a gentle simmer for 5‑6 minutes, stirring frequently. Adjust thickness with reserved pasta water or extra stock as needed.

    Time: PT6M

  8. Add Veggies & Avocado

    Stir the chopped broccoli stems into the sauce and cook 2 minutes until just tender. Remove pan from heat and fold in diced avocado; the cold avocado creates a pleasant contrast.

    Time: PT3M

  9. Combine Pasta & Sauce

    Add the drained pasta to the skillet, toss to coat evenly. Warm through for 1‑2 minutes, adding a splash of reserved pasta water if needed for silkiness.

    Time: PT2M

  10. Serve

    Plate the pasta, garnish with extra toasted walnut pieces, a sprinkle of nutritional yeast, and a grind of black pepper.

    Time: PT2M

  • Cutting board
  • Wooden spoon or silicone spatula
  • Measuring cups & spoons
  • Ladle (optional)
  • Serving bowl (optional)

Critical Steps — Do Not Skip

  • Processing walnut mixture to a coarse crumb, not a paste.
  • Deglazing the walnut crumble with stock.
  • Blending cashew cream until completely smooth.
  • Simmering the sauce without boiling to prevent separation.
  • Folding cold avocado into the hot sauce for texture contrast.

Chef Tips from the Video

  • Toast walnuts and cashews lightly before processing for deeper, nuttier flavor.
  • Add a pinch of smoked paprika to the sauce for subtle smokiness.
  • Reserve a tablespoon of the walnut crumb for garnish to add crunch.
  • If you like extra heat, keep the seeds of the jalapeño.

Troubleshooting

Sauce is too thick.

Add a splash of vegetable stock, pasta water, or plant milk while stirring until desired consistency.

Sauce is watery or thin.

Blend in a few more soaked cashews or simmer a bit longer to reduce.

Walnut crumb is too fine, losing texture.

Pulse the processor for a shorter time or add a handful of coarsely chopped walnuts after processing.

Pasta is overcooked.

Cook pasta al dente next time; you can also briefly re‑heat overcooked pasta in a skillet with a little extra sauce.

Storage

Refrigerator: Store leftovers in an airtight container for up to 3 days. Reheat gently, adding a splash of plant milk or stock.

Freezer: Not recommended due to avocado texture; you may freeze pasta and sauce separately without avocado.

Room temperature: Do not leave at room temperature for more than 2 hours.

Make-Ahead Tips

  • Cook pasta a day ahead, rinse with cold water, and store in the fridge.
  • Prepare the walnut crumb and cashew cream ahead; keep cashew cream in a sealed container.
  • Dice avocado just before serving to maintain its cool texture.
