How to Make It
Preheat the oven to 425°. Generously butter a 10-inch Bundt pan. In a pot of salted boiling water, cook the spaghetti until al dente. Drain well.
In a large bowl, mix the pasta with all of the remaining ingredients. Scrape into the prepared pan and bake until the cheese is melted and bubbling, 35 to 40 minutes.
Transfer the pan to a rack and let cool for 15 minutes. Invert the loaf onto a platter, cut into wedges and serve.
