Instructions
Let’s dive into the steps to create this comforting dish:
Preheat Your Oven: Start by preheating your oven to 375°F (190°C). This ensures the gratin will cook evenly and get that golden, bubbly finish.
Roast the Squash: Cut the spaghetti squash in half, remove the seeds, and roast it in the oven for about 30-40 minutes, or until tender. Once it’s done, use a fork to shred the flesh into spaghetti-like strands.
Prepare the Creamy Sauce: In a pan, melt the butter over medium heat and sauté the garlic until fragrant. Add the heavy cream and bring it to a simmer. Stir in the cheddar cheese, Parmesan, salt, and pepper, allowing it to melt into a velvety sauce.
Combine and Assemble: Mix the shredded spaghetti squash with the creamy sauce and fresh herbs. Pour everything into a greased baking dish, then top with more Parmesan cheese for that perfect crispy topping.
Bake to Perfection: Place the dish in the oven and bake for about 20-25 minutes, or until the top is golden and bubbly.
Serve and Enjoy: Let it cool for a few minutes before serving. Garnish with additional fresh herbs and enjoy this cheesy, comforting dish!
