Ingredients
  

For the squash

  • 1 large spaghetti squash
  • 2 tablespoons olive oil (divided)
  • to taste salt
  • to taste pepper

For the filling

  • 1 onion, chopped
  • 3 cloves garlic, minced
  • 8 oz mushrooms, sliced
  • 4 cups fresh spinach, chopped
  • ½ cup cream cheese
  • ¼ cup grated Parmesan cheese
  • ½ teaspoon red pepper flakes (optional)
  • to taste fresh parsley, chopped (for garnish)

Instructions
 

Preparation

  • Preheat your oven to 400°F (200°C).
  • Slice the spaghetti squash in half lengthwise and scoop out the seeds.
  • Drizzle each squash half with 1 tablespoon of olive oil and season generously with salt and pepper. Place the squash cut-side down on a baking sheet.
  • Roast the squash for 40–45 minutes until the flesh is tender and easily shredded with a fork.

Cooking the Filling

  • While the squash bakes, heat the remaining tablespoon of olive oil in a large skillet over medium heat.
  • Add the chopped onion and sauté until translucent, about 5 minutes.
  • Add the minced garlic and sliced mushrooms to the skillet. Cook, stirring occasionally, until the mushrooms are browned and any liquid has evaporated, about 7–8 minutes.
  • Toss in the chopped spinach, stirring until wilted, about 2–3 minutes.
  • Lower the heat, then stir in the cream cheese. Mix until it’s fully melted and creates a creamy sauce.
  • Add the grated Parmesan cheese and red pepper flakes (if using). Season the mixture with salt and pepper to taste.

Assembly

  • Once the squash is cooked, remove it from the oven and let it cool for a few minutes.
  • Use a fork to scrape the squash into long, spaghetti-like strands, leaving the shell intact.
  • Fill each squash half with the creamy spinach and mushroom mixture, spreading it evenly.
  • Return the stuffed squash halves to the oven and bake for an additional 10–15 minutes, until hot throughout and slightly golden on top.
  • Garnish with chopped fresh parsley before serving.

Notes

This stuffed spaghetti squash can be served as a main dish or as a hearty side. Pair it with a fresh salad or some crusty bread for a complete meal. It's also great for lunch the next day. If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. You can reheat it in the microwave or oven until warmed through.
