Step-by-Step Instructions
Step 1: Prepare the Spaghetti Squash Foundation
Preheat your oven to 425°F (220°C). Cut the spaghetti squash in half lengthwise and scoop out all seeds and pulp using a sturdy spoon. Brush the cut surfaces with 1 tablespoon olive oil and season generously with salt and pepper. Place cut-side down on a parchment-lined baking sheet and roast for 35-40 minutes until the flesh easily separates into strands when tested with a fork.
Step 2: Create the Aromatic Base
While the squash roasts, heat 2 tablespoons olive oil in a large skillet over medium heat. Add diced onion and cook for 4-5 minutes until translucent and fragrant. The key here is patience – properly caramelized onions create the flavor foundation that makes this dish extraordinary.
Step 3: Build the Mediterranean Medley
Add minced garlic to the skillet and cook for 30 seconds until aromatic. Incorporate bell pepper and zucchini, cooking for 6-8 minutes until vegetables are tender-crisp. This timing ensures optimal texture – vegetables that are cooked through but still retain a satisfying bite.
Step 4: Develop the Rich Sauce
Stir in cherry tomatoes, sun-dried tomatoes, and tomato paste. Cook for 2-3 minutes until tomatoes begin to soften and release their juices. Add vegetable broth, oregano, basil, and smoked paprika. Simmer for 10-12 minutes until the sauce reduces by one-third and develops a rich, concentrated flavor.
Step 5: Combine and Finish
Once the spaghetti squash is tender, use a fork to scrape the flesh into long strands. Add the squash strands directly to the skillet with the Mediterranean sauce. Toss gently for 2-3 minutes, allowing the flavors to meld. Remove from heat and stir in fresh basil, lemon juice, and half the pine nuts.

Common Mistakes to Avoid
Overcooking the Squash: Test doneness at 35 minutes – overcooked squash becomes mushy and loses its appealing texture.
Underseasoning: Spaghetti squash has a mild flavor that requires generous seasoning. Season each component separately for optimal taste.
Crowding the Pan: Cook vegetables in batches if necessary to ensure proper caramelization rather than steaming.
Skipping the Resting Period: Allow the finished dish to rest for 3-4 minutes before serving to let flavors meld completely.
Storing Tips for the Recipe
Refrigeration: Store leftovers in airtight containers for up to 4 days. The flavors actually improve overnight as they continue to meld.
Freezing: Freeze portions in freezer-safe containers for up to 3 months. Thaw overnight in refrigerator before reheating.
Reheating: Warm gently in a covered skillet over medium-low heat, adding 1-2 tablespoons vegetable broth if needed to prevent sticking.
Meal Prep: Roast multiple squashes on Sunday and store the strands separately from sauce for quick weeknight assembly.

Q: Can I prepare this recipe ahead of time?
A: Absolutely! Roast the spaghetti squash and prepare the sauce up to 2 days in advance. Store separately and combine when ready to serve.
Q: How do I know when spaghetti squash is perfectly cooked?
A: The flesh should separate easily into long strands when scraped with a fork, but still maintain some firmness. It should not be mushy or waterlogged.

A: Pierce the whole squash several times with a knife tip, then microwave for 2-3 minutes to soften slightly before cutting. Use a sharp, heavy knife and cut slowly with steady pressure.
Q: Can I make this recipe oil-free?
A: Yes! Roast the squash using vegetable broth instead of oil, and sauté vegetables in broth or water, adding small amounts as needed to prevent sticking.
