How to Make Spaghetti Squash Au Gratin
-
Preheat the oven to 400°F (200°C). This step ensures an even roast for your spaghetti squash, which is key to achieving that tender, caramelized texture you want.
-
Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the inside with melted butter, then season with salt and pepper. Place the squash cut-side down on a baking sheet to roast evenly.
-
Roast for 45-60 minutes until tender. You’ll know it’s ready when the flesh easily shreds with a fork, transforming into delightful, spaghetti-like strands.
-
Sauté the onion in a saucepan with the remaining melted butter. Cook until translucent, then add the garlic, allowing its fragrance to fill your kitchen.
-
Create a roux by whisking in flour until combined. Gradually pour in the milk, stirring continuously until the mixture is smooth and has thickened slightly, which should take about 5-7 minutes.
-
Mix in the seasonings along with the melted cheese. Stir until fully incorporated. Add the shredded squash to this creamy cheese sauce, making sure it’s well coated, and transfer everything to a greased baking dish.
-
Combine the remaining cheese with panko breadcrumbs for a tasty topping. Generously sprinkle this mixture over the squash, ensuring every bit is covered for maximum crunch.
-
Bake for 20-25 minutes until the topping is golden brown and bubbly. Once out of the oven, let it rest for a few minutes before serving.
Optional: Garnish with fresh parsley for a dash of color and freshness.
