Preheat oven to 350°F.
Line a 9-inch sprinform pan with parchment paper, allowing edges to hang outside the pan.
In a large pot, cook pasta in boiling water for 10 minutes.
In a large bowl, combine sweet potatoes, cream, pepper, garlic, salt, eggs and goat cheese. Drain spaghetti and mix into sweet potato mixture, tossing to coat the pasta completely. Pour into prepared pan.
Bake for 40 minutes, until set. Allow to cool a bit before removing from pan. Serve warm.
Garnish with sweet potato chips, additional goat cheese and fresh basil.
