Difficulty Level

Ingredients
- 1 medium spaghetti squash (about 3 pounds)
- 2 cups fresh spinach leaves, washed and stems removed
- 1/2 cup walnuts, toasted for depth of flavor
- 1/3 cup extra virgin olive oil, plus extra for drizzling
- 2 cloves garlic, peeled
- 1/3 cup freshly grated Parmesan cheese (optional for vegan option, substitute nutritional yeast)
- 1 tablespoon lemon juice, fresh
- Salt and freshly ground black pepper to taste
- Red pepper flakes (optional, for a subtle kick)
Instructions
- Prepare the spaghetti squash: Preheat your oven to 400°F (205°C).Slice the squash in half lengthwise using a sharp knife. Scoop out the seeds and stringy pulp with a spoon. Drizzle the cut sides with olive oil and sprinkle generously with salt and pepper.
- Place the halves cut-side down on a rimmed baking sheet lined with parchment paper. Roast for 35-40 minutes until the flesh easily pulls apart with a fork into spaghetti-like strands.
- Toast the walnuts: While the squash roasts,toast the walnuts in a dry skillet over medium heat. Stir frequently until fragrant and lightly browned, about 5 minutes. Set aside to cool.
- Make the spinach walnut pesto: In a food processor, combine the toasted walnuts, fresh spinach, garlic cloves, Parmesan cheese (or nutritional yeast), and lemon juice. Pulse until finely chopped.
- With the processor running, slowly drizzle in the extra virgin olive oil until the pesto reaches a smooth, creamy consistency. Scrape down the sides as needed. Season with salt, pepper, and optional red pepper flakes.
- Combine and serve: Onc the squash is done, let it cool slightly. Using a fork,scrape the flesh carefully into a large bowl or directly onto serving plates. Toss gently with the vibrant spinach walnut pesto until perfectly coated.
- Garnish with toasted walnut pieces, additional Parmesan, and a drizzle of olive oil. Serve warm or at room temperature for maximum flavor enjoyment.
Tips for Success
- Spaghetti squash cooking method: For faster cooking, try microwaving the squash halves for 10-12 minutes before roasting to speed up the process.
- Make-ahead pesto: The spinach walnut pesto can be prepared up to 3 days in advance. Store it in an airtight container with a thin layer of olive oil on top to prevent oxidation.
- Ingredient swaps: Replace walnuts with pine nuts or almonds if preferred.For a nut-free version, use sunflower seeds.
- Brighten the pesto: Adjust lemon juice and salt to elevate the pesto’s freshness – a critical balance that highlights the spinach and walnut flavors beautifully.
- Avoid watery pesto: Ensure spinach leaves are well-drained and patted dry before blending to keep the pesto thick and luscious.
