Method
 

Preparation
  1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper. Cut the acorn squash in half lengthwise, scoop out the seeds, and brush the cut sides with olive oil. Season with kosher salt and ground black pepper.
  2. Place squash cut side down on the baking sheet and roast for 35-40 minutes until tender.
  3. In a skillet, heat unsalted butter and olive oil over medium-low heat. Add sliced yellow onions and salt, stirring occasionally for 30-35 minutes until caramelized, adding granulated sugar halfway through.
  4. Add balsamic vinegar and fresh thyme to the onions, stirring for 2 minutes, then remove from heat.
  5. After roasting, flip the squash cut side up and reduce the oven temperature to 375°F (190°C). Fill each squash half with the caramelized onion mixture and top with grated Gruyere cheese.
  6. Bake for an additional 15-20 minutes until the cheese is melted and golden brown.
  7. Let cool slightly, garnish with parsley and thyme, then serve.
