directions

Preheat your oven to 400°F (200°C). Slice the spaghetti squash in half lengthwise and scoop out the seeds.

Brush the inside of each half with olive oil, place cut-side down on a baking sheet, and roast for 35-45 minutes until tender.

While the squash is roasting, soak the raw cashews in hot water for 20 minutes, then drain.

In a blender, combine soaked cashews, non-dairy milk, nutritional yeast, lemon juice, garlic powder, onion powder, smoked paprika, salt, and pepper. Blend until smooth and creamy.

Once the squash is cool enough to handle, use a fork to scrape the inside into spaghetti-like strands.

In a large skillet or saucepan, add the squash strands and pour the vegan cheese sauce over them. Stir well and heat over low-medium until everything is warmed through and evenly coated.

Optional: For a baked version, transfer the mixture to a baking dish, top with breadcrumbs or vegan parmesan, and bake at 375°F (190°C) for 10-15 minutes.
