Description

A comforting and creamy spaghetti squash dish baked to perfection, featuring sautéed mushrooms and a rich cheese sauce.


Ingredients

Scale
  • 1 spaghetti squash
  • 2 cups fresh mixed mushrooms (cremini and shiitake recommended)
  • 1 cup heavy cream
  • 1 cup sharp cheddar cheese, shredded
  • 1 cup Gruyere cheese, shredded
  • 3 cloves garlic, minced
  • 2 tablespoons fresh thyme, chopped
  • 2 tablespoons fresh rosemary, chopped
  • 2 tablespoons butter
  • Salt and pepper to taste

Instructions

  1. Preheat your oven to 400°F (200°C). Slice the spaghetti squash in half lengthwise and scoop out the seeds. Place it cut-side down in a baking dish with a bit of water and roast for 40-50 minutes, until fork-tender.
  2. In a skillet, melt 1 tablespoon of butter over medium heat. Add the sliced mushrooms, season with salt and pepper, and sauté until browned, about 7-10 minutes. Add minced garlic during the last 2 minutes.
  3. In a medium saucepan, melt 1 tablespoon of butter over medium-low heat. Add the heavy cream and bring to a gentle simmer. Stir in the cheeses until melted and creamy, then season with salt, pepper, and herbs.
  4. Once the squash is cooked and slightly cooled, scrape out the flesh with a fork. In a mixing bowl, combine the strands with sautéed mushrooms and the cheese sauce until well incorporated.
  5. Transfer the mixture to a greased baking dish, top with additional cheese if desired, and bake for 20-25 minutes until golden brown and bubbling.
  6. Let cool slightly before serving, garnished with fresh herbs or breadcrumbs.

Notes

Substitutions include coconut milk for a dairy-free version and spinach or kale instead of mushrooms.
