Follow these simple steps to make your Classic Potato Kugel:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare Baking Dish: Grease a 9×13-inch baking dish with some vegetable oil to prevent sticking.
3. Grate Potatoes and Onions: In a large bowl, combine the grated potatoes and onions, mixing well.
4. Drain Excess Liquid: Use a fine mesh strainer or cheesecloth to drain excess liquid from the potato mixture to prevent a soggy kugel.
5. Whisk Eggs: In a separate bowl, whisk together the eggs, vegetable oil, salt, pepper, garlic powder, and paprika if using.
6. Combine Mixtures: Pour the egg mixture into the potato and onion mixture. Stir until everything is evenly combined.
7. Add Flour (Optional): If you prefer a denser kugel, mix in the flour. This step is optional, depending on your texture preference.
8. Transfer to Baking Dish: Pour the entire mixture into the prepared baking dish, spreading it out evenly.
9. Bake: Place in the preheated oven and bake for about 1 hour or until the top is golden brown and crispy.
10. Cool and Serve: Allow the kugel to cool for a few minutes before cutting it into squares and serving warm.

Following these steps will result in a classic Potato Kugel that is sure to impress everyone at your table.
