Spaghetti Squash With Tomato and Feta - A Bright, Simple Weeknight Favorite

Print Recipe Pin Recipe

Prep Time 15 minutes mins

Cook Time 45 minutes mins

Total Time 1 hour hr

Servings: 4 servings

Ingredients Method

Ingredients

  

• 1 medium spaghetti squash (about 3–4 pounds)
• 2 tablespoons olive oil, plus more for drizzling
• 3 cloves garlic, thinly sliced or minced
• 1 pint cherry or grape tomatoes (or 3 medium ripe tomatoes), halved or chopped
• 1/2 teaspoon red pepper flakes (optional, to taste)
• 1 teaspoon dried oregano or Italian seasoning
• 1/2 cup crumbled feta cheese
• 1/4 cup fresh parsley or basil, chopped
• Salt and freshly ground black pepper
• 1 tablespoon lemon juice (optional, but brightens the dish)
• To serve (optional): toasted pine nuts, a drizzle of balsamic glaze, or extra-virgin olive oil

Method

 

1. Preheat and prep. Heat the oven to 400°F (200°C). Line a baking sheet with parchment for easy cleanup. Carefully halve the spaghetti squash lengthwise and scoop out the seeds.
2. Season the squash. Rub the cut sides with about 1 tablespoon olive oil. Season generously with salt and pepper. Place cut side down on the baking sheet.
3. Roast until tender. Bake for 35–45 minutes, depending on size, until the flesh is easily pierced with a fork and strands pull apart. The edges should be lightly caramelized for the best flavor.
4. Make the tomato topping. While the squash roasts, warm 1 tablespoon olive oil in a large skillet over medium heat. Add garlic and red pepper flakes. Cook 30–60 seconds, just until fragrant.
5. Cook the tomatoes. Add the tomatoes, oregano, a pinch of salt, and black pepper. Cook 4–6 minutes, stirring occasionally, until the tomatoes soften and release some juices but still hold their shape. Turn off the heat and stir in lemon juice if using.
6. Shred the squash. When the squash is cool enough to handle, flip the halves and use a fork to pull the strands into “spaghetti.” Leave the strands in the shells or transfer to a serving bowl.
7. Combine. Pour the warm tomato mixture over the squash. Sprinkle with feta and chopped herbs. Toss gently to combine, tasting and adjusting salt, pepper, and lemon.
8. Finish and serve. Drizzle with a little extra-virgin olive oil. For extra texture, add toasted pine nuts or a very light drizzle of balsamic glaze. Serve warm or at room temperature.

What Makes This Special

This dish balances rich and fresh flavors in an easy, weeknight-friendly format. The sweetness of roasted squash pairs beautifully with juicy tomatoes and salty, creamy feta.

A quick sizzle of garlic and red pepper flakes in olive oil brings gentle heat and aroma without much effort. It also happens to be naturally gluten-free and vegetarian, but it doesn’t feel like a compromise. Most important, it’s adaptable—great warm or at room temperature, and even tasty cold the next day.

Keeping It Fresh

Leftovers keep well for about 3–4 days in the fridge, stored in an airtight container. If you plan for leftovers, store the tomato mixture and squash strands separately to keep the texture bouncy. Reheat gently on the stovetop or in the microwave, adding a splash of water or olive oil to loosen.

Freshen with extra herbs and a crumble of feta right before serving.

Health Benefits

Spaghetti squash is a smart swap when you want a lighter, veggie-forward base. It’s naturally low in calories and provides fiber, which supports digestion and helps you feel satisfied. Tomatoes bring vitamin C, potassium, and lycopene, an antioxidant linked to heart health.

Olive oil adds heart-healthy monounsaturated fats, and feta contributes calcium and protein in a modest portion. The end result is a colorful, nutrient-dense plate that feels indulgent without being heavy.

Pitfalls to Watch Out For

• Undercooked squash. If the strands feel crunchy or stiff, it needs more time. Aim for tender strands that separate easily.
• Watery sauce. Overcrowding the pan or using very watery tomatoes can dilute flavor.

  Cook uncovered and let excess moisture evaporate until the juices turn slightly jammy.

• Burnt garlic. Garlic browns fast. Keep the heat moderate and stir often; once it turns golden, add the tomatoes.
• Over-salting. Feta is salty. Season the tomatoes lightly and taste after adding the cheese before you add more salt.
• Mushy textures. Toss gently.

  If you overmix, the squash can break down and turn soggy.

Variations You Can Try

• Mediterranean twist: Add sliced Kalamata olives, capers, and a sprinkle of dried oregano.
• Protein boost: Fold in chickpeas, grilled chicken, or sautéed shrimp for a more filling meal.
• Roasted vegetable mix: Toss in roasted bell peppers, zucchini, or red onion for extra color and sweetness.
• Herb swap: Use dill with feta for a fresh, tangy note, or mint for a cool finish.
• Creamy finish: Stir in a spoonful of Greek yogurt or ricotta off the heat for a silky texture.
• Spice route: Replace red pepper flakes with a pinch of smoked paprika or Aleppo pepper for gentle warmth.
• Crunch factor: Top with toasted breadcrumbs or crushed pistachios right before serving.

FAQ

Can I cook the spaghetti squash in the microwave?

Yes. Pierce the whole squash several times with a knife, microwave 4–5 minutes to soften, then halve and scoop the seeds. Place cut side down in a microwave-safe dish with a little water and cook 8–12 more minutes until tender.

The oven gives better flavor, but the microwave is fast and convenient.

What kind of tomatoes work best?

Cherry or grape tomatoes are reliable year-round and stay sweet and firm. In peak season, any ripe, meaty tomato works well—Roma, vine-ripened, or heirlooms. If using large tomatoes, remove some seeds to reduce wateriness.

Is there a good dairy-free alternative to feta?

Try a high-quality dairy-free feta or crumble firm tofu with a splash of lemon, olive oil, and salt.

You can also use toasted pine nuts for richness and a salty hit from capers or olives.

Can I make this ahead?

You can roast the squash and cook the tomato mixture up to 2 days in advance. Store separately, then reheat, combine, and finish with fresh herbs and feta right before serving. This keeps the texture bright and the flavors fresh.

How do I choose a good spaghetti squash?

Look for one that feels heavy for its size with a firm, matte rind and no soft spots.

A dry, intact stem is a good sign. Store it in a cool, dark place for up to a month before cooking.

What can I serve with this?

A simple green salad with lemon vinaigrette is perfect. For heartier meals, add garlicky grilled bread or roasted chicken.

It also pairs well with a crisp white wine or sparkling water with lemon.

Can I add sauce instead of fresh tomatoes?

Absolutely. A good-quality marinara works well; warm it with garlic and olive oil, then toss with the squash and feta. Adjust salt since jarred sauces can be seasoned already.
