Cooking Instructions for Roasted Spaghetti Squash with Parmesan Mushrooms

Cooking Roasted Spaghetti Squash with Parmesan Mushrooms is an adventure that unfolds with every step. The process is simple yet satisfying, inviting you to savor every moment. Let’s embark on this culinary journey together!
Preheat your oven to 375 degrees F. Lightly coat a large baking sheet with cooking spray and set it aside. This initial step is crucial as it sets the stage for perfectly roasted squash.
Next, halve the spaghetti squash and remove the seeds. Lightly drizzle and rub the insides and outsides of the squash with olive oil, then sprinkle the insides with 1/4 teaspoon kosher salt. Place the cut sides down on the prepared baking sheet, ensuring they are snug against the surface for even roasting.
Bake the squash until it’s fork-tender, which should take about 25 minutes. Let it rest for 10 to 15 minutes until cool enough to handle. The anticipation builds as you wait, and the aroma of roasted squash fills your kitchen!
Once cooled, shred the insides into strands with a fork and set aside. This step transforms the squash into a delightful noodle-like base.
Meanwhile, heat 1 tablespoon of olive oil in a large, deep skillet over medium-high heat. Add the mushrooms and sauté until they turn golden brown, which should take about 8 minutes. It’s essential to let them cook undisturbed for a while to achieve that beautiful caramelization.
Once golden, add the garlic, thyme, remaining kosher salt, and black pepper. Sauté until fragrant, about 1 additional minute. The smell will be irresistible!
Now, add the chopped spinach by handfuls, allowing it to wilt before adding more. Cook just until all of the spinach wilts down, which should take about 2 minutes.
Next, gently fold in the shredded spaghetti squash into the skillet. Cook just until everything is heated through, about 2 minutes. Take a moment to taste and adjust with additional salt and pepper as needed.
Finally, stir in the Parmesan and parsley. The warm mixture will melt the cheese slightly, creating a creamy consistency. Serve warm, topped with additional parsley and Parmesan as desired. Enjoy every bite of your delicious creation!
Things Worth Knowing
