- Red Onion: Adds a subtle sweetness and sharp aromatic kick when sautéed.
- Garlic: No Mediterranean dish is complete without the fragrant punch of fresh garlic.
- Baby Spinach: This leafy green wilts beautifully, adding a nutritious boost and vibrant color to the dish. It’s packed with iron and vitamins.
- Oregano: A classic Mediterranean herb, oregano provides an earthy, slightly peppery flavor that ties all the ingredients together.
- Sun-Dried Tomatoes: These intensely flavored tomatoes offer a concentrated sweetness and tanginess that is truly irresistible. They are a powerhouse of flavor in this dish.
- Sun-Dried Tomato Pesto: Takes the tomato flavor to the next level, adding a creamy, savory depth. You can use store-bought or make your own with my easy homemade sun-dried tomato pesto recipe.

Step-by-Step Guide: Crafting Your Mediterranean Spaghetti Squash
Creating this flavorful dish is a breeze. Follow these detailed instructions to achieve perfect results every time. Each step is designed for clarity, ensuring a smooth and enjoyable cooking process.
Instructions:
- Prepare the Squash: Preheat your oven to 400° F (200°C). Carefully cut the spaghetti squash in half lengthwise. Scoop out and discard the seeds and stringy bits.
- Season and Roast: Brush the cut sides of the spaghetti squash with 1 tablespoon of olive oil. Season generously with ½ teaspoon of sea salt and ½ teaspoon of black pepper. Place the squash halves cut-side down on a baking sheet.
- Roast to Perfection: Roast in the preheated oven for approximately 45 minutes, or until the squash is tender and the strands can be easily pulled away with a fork. Once roasted, remove from the oven and set aside to cool slightly.
- Sauté Aromatics: While the squash cools, add the remaining tablespoon of olive oil to a large skillet and heat over medium flame. Add the diced red onion and sauté for 3-4 minutes until it begins to soften and become translucent.
- Add Greens and Herbs: Stir in the minced garlic and baby spinach. Sprinkle the remaining ½ teaspoon of salt, ½ teaspoon of black pepper, and the oregano over the spinach.
- Finish Sautéing: Continue to sauté for 2-3 minutes until the spinach has wilted. Then, add the sun-dried tomatoes and sauté for another 1-2 minutes to warm them through and release their flavors. Remove the skillet from heat and set aside.
- Create Spaghetti Strands: Once the squash is cool enough to handle, use a fork to scrape the “noodles” out of the shell and transfer them into a large mixing bowl.
- Combine Flavors: Add the sun-dried tomato pesto, lemon juice, and lemon zest to the spaghetti squash strands. Toss gently to ensure the squash is evenly coated. Then, fold in the sautéed spinach and sun-dried tomato mixture.
- Serve and Garnish: Transfer the Mediterranean spaghetti squash to serving bowls. Garnish generously with crumbled feta cheese and diced green onions. Serve immediately and enjoy!
Tips for Success and Variations
To make your Mediterranean spaghetti squash experience even better, consider these extra tips and exciting variations:
- Perfectly Cooked Squash: Don’t overcook the squash, or it will become mushy. It should be tender but still hold its shape. A fork should easily pull the strands apart.
- Homemade Pesto: While store-bought pesto is convenient, a homemade sun-dried tomato pesto can elevate the flavor significantly. It’s surprisingly easy to make and offers a fresher, more vibrant taste.
- Add Protein: For a more substantial meal, consider adding grilled chicken, shrimp, white beans, or chickpeas to your dish. These additions will complement the Mediterranean flavors beautifully.
- Extra Veggies: Feel free to customize with other vegetables! Roasted bell peppers, zucchini, Kalamata olives, or artichoke hearts would be delicious additions.
- Spice it Up: A pinch of red pepper flakes can add a lovely kick if you enjoy a bit of heat.
- Meal Prep Friendly: This dish makes fantastic leftovers! Store in an airtight container in the refrigerator for up to 3-4 days. It reheats well in the microwave or on the stovetop.

This Mediterranean Spaghetti Squash offers a new, exciting way to enjoy this versatile vegetable.
