How to Make Roasted Spaghetti Squash with Mushrooms

  1. Preheat oven: Set your oven to 400°F (200°C) and prepare a baking sheet lined with parchment paper for easy cleanup.

  2. Prepare the squash: Carefully halve the spaghetti squash lengthwise and scoop out the seeds. Brush the insides with extra-virgin olive oil and sprinkle with kosher salt.

  3. Bake squash: Place the squash cut sides down on the baking sheet. Bake for about 25-30 minutes, or until the flesh is tender and easily pierced with a fork.

  4. Sauté mushrooms: In a large skillet over medium heat, warm a splash of extra-virgin olive oil. Add the sliced cremini mushrooms and sauté for about 8 minutes, stirring until they turn golden brown.

  5. Add garlic and herbs: Toss in the minced garlic, fresh thyme, salt, and black pepper to the skillet. Cook for an additional minute until fragrant and inviting.

  6. Incorporate spinach: Gradually add the fresh spinach to the skillet. Stir until the spinach has wilted down, about 2 minutes.

  7. Mix it all together: Remove the baked squash from the oven and let it cool slightly. Use a fork to shred the squash into spaghetti-like strands. Combine in the skillet with the mushroom-spinach mixture. Finish by mixing in the Parmesan cheese until melted and everything is deliciously combined.

Optional: Garnish with extra parsley and a sprinkle of Parmesan before serving for an added touch of flavor.

Expert Tips for Roasted Spaghetti Squash with Mushrooms

  • Perfecting the Bake: Avoid overcooking the spaghetti squash to prevent mushiness. A fork should easily pierce the flesh, indicating it’s ready.

  • Prep Ahead: To streamline dinner, roast the spaghetti squash in advance, then simply reheat the squash and sautéed mixture when it’s mealtime.

  • Cheese Alternatives: If you’re aiming for a vegan version, nutritional yeast works wonders—just sprinkle it generously for that cheesy flavor without dairy.

Roasted Spaghetti Squash with Mushrooms Recipe FAQs

How do I choose a ripe spaghetti squash?
When selecting a spaghetti squash, look for one that has a firm, hard shell with a uniform golden-yellow color. Avoid any with soft spots, dark blemishes, or cracks—the squash should feel heavy for its size. A good rule of thumb is to give it a gentle tap; if it sounds hollow, you’re on the right track!

How should I store leftover roasted spaghetti squash with mushrooms?
Leftover roasted spaghetti squash with mushrooms can be stored in an airtight container in the refrigerator for up to 3 days. Make sure to let it cool completely before sealing it to minimize moisture buildup. You can enjoy it cold or reheat it in the microwave or skillet—just add a splash of olive oil to revive its delicious flavors!

Can I freeze roasted spaghetti squash with mushrooms?
Absolutely! To freeze, allow the dish to cool completely. Then, portion it into freezer-safe bags or containers and label them with the date. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it, thaw in the refrigerator overnight and reheat gently in a skillet over medium heat, adding a splash of olive oil for extra moisture.

What if my spaghetti squash is mushy after baking?
If your spaghetti squash becomes mushy, it might have been overcooked. To prevent this in the future, keep an eye on it during baking—between 25 to 30 minutes at 400°F should suffice. Aim for the flesh to be tender yet firm enough to hold its shape. If you encounter mushiness, you can transform it into a sauce by blending it with herbs and some tomato sauce for a delectable pasta alternative.

Are there any dietary considerations for this dish?
Yes, this recipe is vegetarian and gluten-free, making it a great choice for various dietary needs! If you’re making it vegan, a simple swap of Parmesan for nutritional yeast will do the trick.
