Cheddar Cheese: Sharp, melty, and irresistible. It gives the gratin its signature richness and flavor.

Parmesan Cheese: Adds a salty, nutty punch that pairs beautifully with the creamy base.

Heavy Cream: This is what makes the dish so luscious. It helps melt the cheeses and gives everything a silky texture.

Garlic: A little fresh garlic goes a long way in deepening the flavor of the gratin.

Salt and Pepper: Simple seasonings that bring everything together and enhance the natural flavors of the dish.

Instructions

Let’s dive into the steps to create this cheesy, bubbly masterpiece:

Preheat Your Equipment: Preheat your oven to 400°F (200°C). This ensures even roasting and perfectly cooked squash strands.

Prepare the Spaghetti Squash: Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the inside with a bit of olive oil, season with salt and pepper, and place cut side down on a baking sheet. Roast for about 35–40 minutes or until the flesh is tender and easily scraped into strands.

Sauté the Garlic: In a small skillet, melt the butter over medium heat. Add the minced garlic and sauté for 1–2 minutes, just until fragrant. Don’t let it brown this is where the flavor magic starts.

Combine Ingredients: In a large bowl, combine the roasted spaghetti squash strands with the sautéed garlic, heavy cream, cheddar cheese, and half of the Parmesan. Stir everything together until evenly coated.

Prepare Your Baking Dish: Lightly grease a casserole dish or gratin dish. This keeps everything from sticking and makes cleanup easy.

Assemble the Dish: Pour the squash mixture into the prepared baking dish and spread it out evenly. Top with the remaining Parmesan cheese and a little extra cheddar if you’re feeling cheesy (and who isn’t?).

Cook to Perfection: Bake for 15–20 minutes until the top is golden and bubbly. You can broil it for the last 2 minutes if you want a beautifully browned crust.

Finishing Touches: Remove from the oven and let it rest for about 5 minutes. This gives the dish time to settle and makes serving easier.

Serve and Enjoy: Scoop onto plates while it’s still warm and melty. It’s creamy, cheesy, and loaded with flavor comfort food at its finest.
