# Method:

01 - Cook fettuccine in large pot of salted boiling water until al dente. Reserve 1/2 cup pasta water before draining.

03 - Sprinkle brown sugar over onions and continue cooking, stirring frequently, until deeply caramelized and golden, 15-20 more minutes.
04 - Add minced garlic and chopped red chili pepper to caramelized onions. Sauté 1-2 minutes until fragrant.
05 - Stir in honey, heavy cream, Parmesan, red pepper flakes, and black pepper. Simmer gently 2-3 minutes until sauce thickens slightly.

07 - Taste and adjust seasoning as needed. Serve hot garnished with fresh parsley and extra Parmesan cheese.
