The creamiest lemon zucchini pasta made without dairy:

This lemon zucchini pasta is creamy, bright, and deeply flavorful — no cheese required. The sauce relies on dairy-free milk and a light roux to create a silky texture, while lemon zest and juice give it a fresh zing. Searing the zucchini adds a savory caramelized note that balances the citrus.

Even picky eaters will enjoy it — the combination of textures and flavors makes it easy to serve as a weeknight main or a light dinner for guests.

The technique is simple: cook pasta, sear zucchini with shallot and garlic, make a quick lemony sauce using dairy-free milk and a small roux, then toss everything together and finish with crunchy sourdough pangrattato flavored with pine nuts and parsley.

This recipe uses common pantry ingredients — olive oil, pasta, flour or cornstarch, and citrus — plus a few fresh items. It’s flexible, fast, and perfect for summer when zucchini is at its best.

Simple Ingredients:

  • Pasta: Choose shapes that hold sauce well, such as fusilli, conchiglie, or orecchiette. Use gluten-free pasta if needed.
  • Lemon: Both zest and juice are used for brightness.
  • Zucchini: Sliced and seared until golden.
  • Garlic and shallot: Provide the savory base.
  • Dairy-free milk: Oat, almond, soy, or cashew milk work. Cashew and oat milk give extra creaminess; avoid coconut if you want a neutral flavor.
  • Flour or cornstarch: A small amount thickens the sauce. Use cornstarch for a gluten-free option.

For the sourdough pangrattato:

  • Day-old sourdough (pulsed into crumbs)
  • Olive oil
  • Pine nuts
  • Garlic powder and dried or fresh parsley
  • Sea salt

Key tips for making this dish:

  • Make the roux separately: Whisk flour or cornstarch into a small portion of dairy-free milk first to avoid lumps, then add it into the warm milk and lemon mixture to thicken evenly.
  • Use fresh lemon: Fresh juice and zest provide the best bright, acidic flavor; bottled lemon juice can taste flat.
  • Reserve pasta water: A splash of starchy pasta water helps the sauce cling to the noodles and adds body without extra ingredients.

Ingredients

Lemon Zucchini Pasta

  • 1 tbsp olive oil
  • 3 shallots, minced
  • 4 cloves garlic, minced
  • 2 large zucchinis, sliced
  • 16 ounces pasta of choice
  • 1 1/2 cups (360 mL) dairy-free milk
  • 1 tbsp all-purpose flour or cornstarch
  • 2 large lemons
  • 2 tbsp fresh lemon zest
  • 1/2 tsp sea salt, or to taste
  • Fresh parsley, to garnish

Sourdough Pangrattato

  • 2–3 slices day-old sourdough
  • 1/2 tbsp olive oil
  • 1/4 cup pine nuts
  • 1 tsp dried parsley (or fresh)
  • 1 tsp garlic powder
  • 1/2 tsp sea salt

Instructions

  1. Prep: Wash and slice the zucchini, mince shallot and garlic. Bring a large pot of salted water to a boil for the pasta. Preheat the oven to 400°F and line a baking sheet with parchment.
  2. Toast the bread: Arrange sourdough on the baking sheet and toast for about 10 minutes until crunchy.
  3. Pulse crumbs: Pulse the toasted bread in a food processor to make coarse breadcrumbs and set aside.
  4. Sauté zucchini: In a large pan, heat olive oil over medium. Sauté shallot and garlic until fragrant, add zucchini, reduce heat to low, cover for 3–5 minutes, then uncover and continue to sauté until edges are seared. Season with salt.
  5. Cook pasta: Add pasta to boiling water and cook according to package directions until al dente.
  6. Make the roux: Whisk 1/2 cup (120 mL) dairy-free milk with the flour or cornstarch until smooth and lump-free.
  7. Make the sauce: Pour the remaining milk (about 1 cup / 240 mL) into a saucepan with lemon zest and the juice of 2 lemons. Stir in the roux and cook over medium-low until the sauce thickens. Remove from heat and cover.
  8. Toss pasta: When pasta is al dente, reserve 1/3–1/2 cup pasta water, drain most of the water, then combine pasta with the sauce and a splash of pasta water to help the sauce coat the noodles. Cover and set aside.
  9. Finish pangrattato: In a medium skillet, heat olive oil over medium heat, add breadcrumbs, pine nuts, garlic powder, parsley, and salt. Sauté until golden and fragrant, then remove from heat.
  10. Serve: Plate the pasta, sprinkle with pangrattato and fresh parsley, and finish with extra lemon zest if desired. Store leftovers in an airtight container in the fridge up to 4 days; store pangrattato separately.

Notes

Gluten free: Substitute gluten-free pasta and bread, and use cornstarch instead of flour.
