Ingredients

• 1 medium spaghetti squash (about 3-4 pounds)
• 1 cup cashews, soaked for 2 hours
• 1 cup unsweetened almond milk (or any plant-based milk)
• 1/4 cup nutritional yeast (for cheesy flavor)
• 2 tablespoons olive oil
• 1 medium onion, diced
• 3 cloves garlic, minced
• 1 red bell pepper, diced
• 2 cups fresh spinach, chopped
• 1 cup cherry tomatoes, halved
• 1 teaspoon smoked paprika
• 1 teaspoon dried oregano
• Salt and black pepper, to taste
• 1 cup vegan mozzarella cheese (optional for topping)
• Fresh basil, chopped for garnish

Equipment

• Baking sheet (for roasting spaghetti squash)
• Large skillet (for sautéing veggies)
• Food processor or blender (for cashew sauce)
• Mixing bowl
• 9×13 inch casserole dish
• Knife and cutting board
• Spatula or wooden spoon

Instructions

1. Prepare the spaghetti squash: Preheat your oven to 400°F (200°C). Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle with 1 tablespoon olive oil and sprinkle with salt and pepper. Place cut-side down on a baking sheet and roast for 35-40 minutes until tender.
2. Make the cashew cheese sauce: While the squash roasts, drain the soaked cashews and add them to a food processor with almond milk, nutritional yeast, 1 tablespoon olive oil, a pinch of salt, and garlic powder. Blend until smooth and creamy. Adjust the consistency with more almond milk if needed.
3. Sauté the vegetables: In a large skillet, heat 1 tablespoon olive oil over medium heat. Add diced onion and garlic, sauté until translucent about 3-4 minutes. Add diced bell pepper, chopped spinach, and cherry tomatoes. Cook until spinach wilts and tomatoes soften, about 5 minutes. Season with smoked paprika, oregano, salt, and black pepper.
4. Combine the squash and veggies: Once the spaghetti squash is cool enough to handle, use a fork to scrape out the strands into a mixing bowl. Add the sautéed vegetables and pour in the cashew cheese sauce. Stir gently to combine everything evenly.
5. Assemble the casserole: Transfer the mixture into your 9×13 inch casserole dish, spreading it out evenly. If using, sprinkle vegan mozzarella cheese on top for a golden crust.
6. Bake the casserole: Bake at 375°F (190°C) for 20-25 minutes, until the casserole is heated through and the top is slightly browned.
7. Garnish and serve: Remove from oven and let it cool for 5 minutes. Garnish with fresh chopped basil before serving.

Tips & Variations

For a nut-free version, substitute the cashew cheese sauce with a creamy tahini sauce or a blended tofu-based sauce.

Try these variations to keep things interesting:

• Add cooked mushrooms or zucchini for extra veggies
• Mix in some cooked vegan sausage or crumbled tempeh for protein boost
• Spice it up with a pinch of red pepper flakes or cayenne
• Use vegan parmesan or other vegan cheese alternatives for different flavors
• Incorporate fresh herbs like thyme or rosemary for added aroma

Don’t hesitate to experiment! Each tweak can bring a new twist to this already delightful casserole.
