Ingredients:
- 1 medium spaghetti squash (approx. 3 lbs)
- 2 tbsp olive oil
- 1/2 tsp salt
- 1/4 tsp black pepper
- 3 tbsp unsalted butter
- 3 tbsp all-purpose flour
- 1 1/2 cups whole milk, warmed
- 2 cups sharp cheddar cheese, shredded
- 1/2 cup grated Parmesan cheese
- 1/2 tsp garlic powder
- 1/4 tsp salt
- 1/8 tsp ground nutmeg
- 1/2 cup panko breadcrumbs
- 2 tbsp melted butter
- 1/4 cup extra Parmesan cheese
Instructions:
- Preheat oven to 400°F (200°C). Cut the squash in half lengthwise and scoop out the seeds.
- Brush the interior of the squash with olive oil and sprinkle with salt and pepper.
- Place squash cut-side down on a baking sheet and roast for 40–50 minutes until the skin is easily pierced with a fork.
- Once cool enough to touch, use a fork to scrape the flesh into strands and transfer them to a 9x13 inch baking dish.
- Melt 3 tbsp butter in a saucepan over medium heat. Whisk in flour and cook for 1–2 minutes until pale and nutty.
- Slowly pour in warm milk, whisking constantly. Simmer until the sauce thickens enough to coat the back of a spoon.
- Remove from heat. Stir in the cheddar, 1/2 cup Parmesan, garlic powder, nutmeg, and salt until smooth.
- Pour the cheese sauce over the shredded squash in the baking dish and fold gently to coat.
- Mix panko breadcrumbs and 1/4 cup Parmesan with melted butter, then sprinkle evenly over the top of the squash.
- Bake or broil until the topping is golden brown and bubbling.
