Cut the squash: Carefully slice each spaghetti squash in half lengthwise, then scoop out the seeds and stringy fibers for a clean base.
(Optional) Soften the squash: If desired, microwave each half with large slits for 5-10 minutes; this helps to soften the squash for easier cutting.
Season the squash: Drizzle olive oil on the cut sides and generously sprinkle with salt and pepper to enhance the flavors during roasting.
Bake the squash: Place the squash halves cut side down on a parchment-lined baking sheet and roast for 30-40 minutes, or until they are soft to the touch.
Prepare the filling: While the squash is baking, heat 1 tablespoon of olive oil in a large skillet over medium heat, creating a perfect saut ing environment.
Cook the sausage and mushrooms: Add the crumbled spicy Italian sausage and sliced mushrooms to the skillet, cooking for about 5 minutes, until the sausage is browned. Drain any excess fat if you prefer.
Add the aromatics: Stir in minced garlic, Italian seasoning, and a dash of red pepper flakes, followed by the chopped cherry tomatoes (saving a few for topping later).
Incorporate the spinach: Gradually fold in fresh spinach and cook until it wilts down, creating a colorful and nutritious filling.
Cool the squash: Remove the roasted squash from the oven and flip the halves cut side up, letting them cool slightly before filling.
Stuff the squash: Generously divide the savory sausage mixture among the four squash halves, then top with the reserved cherry tomatoes and a sprinkle of shredded Parmesan cheese.
Final bake: Return the stuffed squash halves to the oven and roast for an additional 15 minutes, or until the cheese melts into a bubbly, golden topping.
Garnish before serving: Finish off with a sprinkle of fresh thyme for a delightful aroma and touch of elegance.
