  • Diet: Vegetarian

Description

A comforting and creamy dish made with buttery spaghetti squash, sautéed mushrooms, and a rich cheese sauce, perfect for cozy dinners.

Ingredients

Scale
  • 1 medium Spaghetti Squash
  • 3 tablespoons unsalted Butter
  • 1 cup Fresh Mushrooms (cremini, shiitake, or button)
  • 2 cloves Fresh Garlic, minced
  • 1 cup Heavy Cream
  • 1 cup sharp Cheddar Cheese, shredded
  • 1 cup Gruyère Cheese, shredded
  • 1 teaspoon Fresh Thyme or Rosemary
  • Salt, to taste
  • Pepper, to taste

Instructions

  1. Preheat your oven to 400°F (200°C). Cut the spaghetti squash in half lengthwise, scoop out the seeds, and brush the insides with melted butter. Sprinkle with salt and pepper. Place cut-sides down on a baking sheet and roast for about 40 minutes or until tender.
  2. In a skillet over medium heat, melt a bit of butter. Add freshly chopped mushrooms and minced garlic, cooking them until they’re tender and golden—about 5-7 minutes. Season lightly with salt and pepper.
  3. In a separate saucepan, combine heavy cream and a sprinkle of salt. Heat over medium-low until warm. Gradually stir in the shredded cheeses until melted and smooth.
  4. Once the spaghetti squash is cooked and cool enough to handle, use a fork to scrape out the strands and place them in a mixing bowl. Gently fold in the sautéed mushrooms and creamy cheese sauce, ensuring everything is well-coated.
  5. Transfer this mixture to a greased baking dish. If you like a crispy top, sprinkle additional cheese on the surface before baking. Bake at 400°F (200°C) for about 25-30 minutes or until bubbly and golden brown.
  6. Let it cool slightly before serving and sprinkle with fresh herbs just before serving for that vibrant final touch.

Notes

Patience is key when cooking spaghetti squash; roasting enhances the flavor. Avoid rushing the sautéing process to fully develop the mushroom flavor.
