Why This Zucchini Butter Pasta Is Good for You

Rich in fiber: Zucchini adds a generous dose of fiber, supporting digestion and helping you feel fuller longer.
Low in saturated fat: The butter in this recipe is balanced by the lightness of olive oil, making it a healthier option than traditional butter-heavy sauces.
Protein-packed: Thanks to Parmesan and walnuts, this dish provides plenty of muscle-building protein.
Vitamin boost: Zucchini and lemon juice deliver vitamins C and A for healthy skin and a strong immune system.
Multi-diet friendly: This can easily be adapted for vegetarian or gluten-free diets (see our Dietary Modifications section below).

Wholesome Ingredients for This Zucchini Butter Pasta

We chose each ingredient here with both nutrition and taste in mind. Here are a few standouts:

Zucchini: The star of this dish! Zucchini is low in calories and high in water content, making it perfect for a creamy pasta that’s also light. Make sure to choose firm, unblemished zucchinis for maximum freshness.
Lemon juice: This brightens up the sauce and adds a burst of vitamin C. If fresh lemons aren’t available, a high-quality bottled lemon juice works as well.
Walnuts: Toasted walnuts contribute healthy omega-3 fats and crunch. If you’re nut-free, sunflower seeds are a great substitute.
Parmesan cheese: We love Parmesan for its flavor and protein content. Nutritional yeast is a vegan alternative that still delivers that “cheesy” goodness.

Ingredients for Zucchini Butter Pasta

1 tablespoon extra-virgin olive oil, plus more for serving
2 pounds zucchini (about 4 medium), coarsely grated
6 garlic cloves, finely chopped
Salt and pepper, to taste
1 cup vegetable stock
¼ cup unsalted butter
1 pound fusilli or other short pasta
1½ cups finely grated Parmesan, plus more for serving
3 tablespoons lemon juice (from 2 lemons)
Big handful of basil leaves, torn
1 cup toasted walnuts, roughly chopped

How to Make Zucchini Butter Pasta

Heat a large skillet (12-inch) on medium-high and add the olive oil. Once hot, stir in the coarsely grated zucchini and garlic. Generously season with salt and pepper.
Pour in the vegetable stock, reduce the heat to medium, and let the mixture cook, stirring occasionally. Wait 15–20 minutes until the zucchini becomes tender and most of the stock has reduced. Stir in the butter until fully melted, forming a chunky, thick sauce. Taste the sauce and adjust with more salt and pepper if needed.
Meanwhile, bring a large pot of salted water to a boil. Add the pasta and cook until al dente. Reserve about 1½ cups of the starchy pasta water before draining.
Add the cooked pasta to the zucchini sauce along with the Parmesan, lemon juice, and reserved pasta water (a little at a time) to loosen the sauce. Gently mix until the pasta is evenly coated and creamy. Taste again and adjust the seasoning as needed.
Garnish with torn basil leaves, chopped toasted walnuts, additional Parmesan, and a drizzle of olive oil for serving.

How to Customize This Zucchini Butter Pasta for Your Diet

Vegetarian: Already perfect for vegetarians! Just ensure your Parmesan is made with vegetarian-friendly rennet if needed.
Vegan: Swap the butter for vegan margarine and use nutritional yeast instead of Parmesan.
Gluten-free: Use a gluten-free pasta made from chickpeas, lentils, or rice.
Low-carb/Keto: Substitute the pasta with zucchini noodles or shirataki noodles for an ultra-light version.
Nut-free: Omit the walnuts and consider toasted pumpkin seeds or sunflower seeds for crunch.

Our Team’s Tips for the Best Zucchini Butter Pasta

Don’t rush the zucchini: Let it simmer until it softens and melds with the butter to create a luxurious sauce.
Toast the walnuts: Toss the walnuts in a dry skillet over medium heat until fragrant to bring out their nutty flavor.
Use high-quality Parmesan: Freshly grated Parmesan melts beautifully and adds a fantastic umami punch.
Save that pasta water: Starchy water helps bind the sauce to the pasta for that creamy texture.
Double the recipe for leftovers: This pasta tastes even better the next day, making it a great meal-prep option.
Reheat smartly: Add a splash of water or vegetable stock when reheating to avoid drying out the pasta.
