Vegan Spaghetti Squash Mac Cheese: A Delicious & Healthy Recipe

June 11, 2025 by DottieDinner

Vegan Spaghetti Squash Mac Cheese: Prepare to have your mind blown! Forget everything you thought you knew about vegan comfort food because this recipe is about to redefine it. Imagine a creamy, cheesy sauce, so rich and decadent you won’t believe it’s dairy-free, blanketing tender strands of naturally sweet spaghetti squash. This isn’t just a meal; it’s an experience.

Mac and cheese, in its various forms, has been a beloved staple in American cuisine for generations. Its origins can be traced back to macaroni and cheese recipes found in medieval Europe, but it truly gained popularity in the United States thanks to Thomas Jefferson, who brought a pasta machine back from Europe and served macaroni pie at a state dinner in 1802. Over time, it evolved into the comforting, cheesy dish we all know and love.

But what if you’re looking for a healthier, plant-based twist on this classic? That’s where this Vegan Spaghetti Squash Mac Cheese comes in. People adore mac and cheese for its creamy texture, satisfying flavor, and the sheer comfort it provides. This vegan version delivers all of that and more. The spaghetti squash adds a subtle sweetness and a delightful texture that complements the creamy cashew-based sauce perfectly. It’s a dish that’s both incredibly satisfying and surprisingly nutritious. Plus, it’s relatively easy to make, making it perfect for a weeknight dinner or a special occasion. Get ready to indulge in a guilt-free, plant-powered version of your favorite comfort food!

Vegan Spaghetti Squash Mac Cheese this Recipe

Ingredients:

  • 1 medium spaghetti squash (about 2-3 pounds)
  • 1 tablespoon olive oil
  • 1 teaspoon salt, plus more to taste
  • ½ teaspoon black pepper, plus more to taste
  • 1 cup raw cashews, soaked in hot water for at least 30 minutes (or boiled for 15 minutes)
  • ¾ cup nutritional yeast
  • ½ cup unsweetened plant-based milk (almond, soy, or oat milk work well)
  • ¼ cup lemon juice
  • 2 tablespoons Dijon mustard
  • 1 teaspoon garlic powder
  • ½ teaspoon onion powder
  • ¼ teaspoon smoked paprika (optional, for added flavor)
  • Pinch of cayenne pepper (optional, for a little heat)
  • Salt and pepper to taste
  • Optional toppings: breadcrumbs, chopped parsley, vegan parmesan cheese

Preparing the Spaghetti Squash:

  1. Preheat your oven to 400°F (200°C). This is crucial for even cooking. While the oven is heating, let’s get the squash ready.
  2. Prepare the squash. Carefully cut the spaghetti squash in half lengthwise. This can be a bit tough, so use a sharp knife and be cautious. You can microwave the squash for a few minutes to soften it slightly if you’re having trouble.
  3. Remove the seeds. Scoop out the seeds and stringy bits from the center of each squash half. A spoon works well for this. Discard the seeds or save them for roasting later!
  4. Season the squash. Drizzle the cut sides of the squash with olive oil. Then, sprinkle generously with salt and pepper. Make sure to coat the entire surface.
  5. Roast the squash. Place the squash halves cut-side down on a baking sheet lined with parchment paper. This prevents sticking and makes cleanup easier. Roast in the preheated oven for 45-60 minutes, or until the squash is tender and you can easily pierce the flesh with a fork. The cooking time will vary depending on the size of your squash.
  6. Let the squash cool slightly. Once the squash is cooked, remove it from the oven and let it cool for about 10-15 minutes. This will make it easier to handle.
  7. Shred the squash. Using a fork, shred the spaghetti squash flesh into strands. It should easily separate into spaghetti-like strands. Transfer the shredded squash to a large bowl.

Making the Vegan Cheese Sauce:

  1. Drain the cashews. Drain the soaked cashews and rinse them thoroughly. This removes any excess starch and ensures a smooth sauce.
  2. Blend the sauce ingredients. In a high-speed blender (such as a Vitamix or Blendtec), combine the drained cashews, nutritional yeast, plant-based milk, lemon juice, Dijon mustard, garlic powder, onion powder, smoked paprika (if using), and cayenne pepper (if using).
  3. Blend until smooth and creamy. Blend the mixture on high speed until it is completely smooth and creamy. This may take a few minutes, depending on the power of your blender. If the sauce is too thick, add a little more plant-based milk, one tablespoon at a time, until you reach your desired consistency.
  4. Taste and adjust seasonings. Taste the sauce and adjust the seasonings as needed. Add more salt, pepper, nutritional yeast, or lemon juice to your liking. Remember that the flavors will mellow out slightly when the sauce is heated.

Combining the Squash and Sauce:

  1. Pour the sauce over the squash. Pour the vegan cheese sauce over the shredded spaghetti squash in the large bowl.
  2. Mix well. Gently toss the squash and sauce together until the squash is evenly coated. Be careful not to overmix, as you don’t want to break down the squash strands too much.
  3. Heat through (optional). You can serve the mac and cheese immediately, or you can heat it through for a warmer dish. To heat it, you can either microwave it for a few minutes, stirring occasionally, or transfer it to a baking dish and bake it in the oven at 350°F (175°C) for 15-20 minutes.

Serving and Optional Toppings:

  1. Serve immediately. Serve the vegan spaghetti squash mac and cheese immediately.
  2. Add toppings (optional). Top with your favorite toppings, such as breadcrumbs, chopped parsley, or vegan parmesan cheese. A sprinkle of extra smoked paprika is also a nice touch.

Tips and Variations:

  • Soaking the cashews: Soaking the cashews is essential for a smooth and creamy sauce. If you’re short on time, you can boil the cashews for 15 minutes instead of soaking them.
  • Nutritional yeast: Nutritional yeast is what gives the sauce its cheesy flavor. Don’t skip it! You can find it at most health food stores or online.
  • Plant-based milk: I prefer to use unsweetened almond milk or oat milk, but any plant-based milk will work. Just make sure it’s unsweetened so it doesn’t affect the flavor of the sauce.
  • Lemon juice: The lemon juice adds a brightness to the sauce and helps to balance the richness of the cashews.
  • Smoked paprika: Smoked paprika adds a smoky flavor that complements the cheesy sauce. If you don’t have it, you can omit it, but I highly recommend using it if you can.
  • Add vegetables: Feel free to add other vegetables to the mac and cheese, such as broccoli florets, peas, or spinach. Simply steam or sauté the vegetables before adding them to the squash and sauce.
  • Spice it up: If you like a little heat, add a pinch of cayenne pepper or a dash of hot sauce to the sauce.
  • Bake it: For a more decadent mac and cheese, transfer the mixture to a baking dish, top with breadcrumbs, and bake in the oven at 350°F (175°C) for 20-25 minutes, or until the breadcrumbs are golden brown.
  • Make it ahead: You can make the vegan cheese sauce ahead of time and store it in the refrigerator for up to 3 days. When you’re ready to serve, simply heat the sauce and toss it with the cooked spaghetti squash.
  • Gluten-free breadcrumbs: If you’re gluten-free, use gluten-free breadcrumbs for the topping.
  • Vegan parmesan cheese: There are many vegan parmesan cheese recipes available online. You can also find store-bought vegan parmesan cheese at some health food stores.
  • Storage: Store leftover vegan spaghetti squash mac and cheese in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven.

Troubleshooting:

  • Sauce is too thick: If the sauce is too thick, add more plant-based milk, one tablespoon at a time, until you reach your desired consistency.
  • Sauce is too thin: If the sauce is too thin, you can add a tablespoon of cornstarch or tapioca starch to thicken it. Mix the starch with a little cold water to form a slurry before adding it to the sauce.
  • Sauce is not cheesy enough: If the sauce is not cheesy enough, add more nutritional yeast, one tablespoon at a time, until you reach your desired flavor.
  • Squash is too watery: If the spaghetti squash is too watery after shredding, you can squeeze out the excess water with a clean kitchen towel.

Health Benefits of Spaghetti Squash:

  • Low in calories: Spaghetti squash is a low-calorie food, making it a great option for weight management.
  • High in fiber: It’s also high in fiber, which can help you feel full and satisfied, and can also aid in digestion.
  • Rich in vitamins and minerals: Spaghetti squash is a good source of vitamins A and C, as well as potassium and manganese.
  • Antioxidant properties: It contains antioxidants that can help protect your cells from damage.
  • Gluten-free: Naturally gluten-free, making it a suitable choice for those with gluten sensitivities or celiac disease.
