Directions

1. Preheat oven to 325 degrees.
2. Heat oil in a large skillet over medium-high heat. Add onions and cook until translucent. Remove from heat and let cool.
3. In the bowl of an electric mixer fitted with the paddle attachment, combine fish, cooled onions, eggs, water, matzah meal, salt, pepper, and sugar. Beat on medium speed for 15 minutes. Add grated carrots and mix until well combined.
4. Transfer mixture to 12-cup bundt pan, smoothing top with a spatula. Place bundt pan in a larger baking dish and fill baking dish 2-inches high with water. Transfer to oven and bake for 1 hour. Cover bundt pan with parchment paper-lined foil and continue baking until center feels solid when a wooden skewer is inserted into the center, about 1 hour more.
5. Remove bundt pan from oven and let stand 5 minutes. Invert onto a flat serving plate and refrigerate overnight. Slice and serve garnished with parsley.
