Ingredients

• 4 lbs Russet or Yukon Gold potatoes, peeled
• 1 large onion, finely chopped or grated
• 8-10 slices thick-cut bacon, diced
• 3 large eggs, beaten
• 1 cup whole milk or heavy cream (or a mix)
• 2 teaspoons salt, or to taste
• 1/2 teaspoon freshly ground black pepper, or to taste
• Optional: 1 bay leaf (for baking), 1/2 teaspoon dried marjoram
• Optional Topping: Sour cream, lingonberry jam (for serving)

Directions

1. Prep the Potatoes: This is the most crucial step for perfect Kugelis!
   1. Peel and Rinse: Start by thoroughly peeling all your potatoes. Give them a quick rinse under cold water to remove any lingering dirt.
   2. Grate with Care: You have two main options here:
   3. Box Grater: Use the fine side of a box grater. This creates a finer texture that helps the pudding bind beautifully. It’s a bit of an arm workout, but traditional.
   4. Food Processor: For a faster method, use the fine grating disc on your food processor. Work in batches to avoid overloading the machine.
   5. Drain Properly: Immediately after grating, the potatoes will release a lot of liquid. This moisture control is key! Transfer the grated potatoes to a cheesecloth-lined colander or a very fine mesh sieve. Gather the ends of the cheesecloth and twist tightly, squeezing out as much liquid as you possibly can. Don't skip this! The more liquid you remove, the crispier and less watery your Kugelis will be. You should see a significant amount of starchy water come out. Visual cue: The potato shreds will look drier and more compact after draining.
   6. Prevent Oxidation: As you work, keep the grated potatoes submerged in cold water until ready to drain and use, or work quickly to combine them with other ingredients to minimize browning.
2. Cook the Bacon and Onions:
   1. Crisp the Bacon: In a large skillet, cook the diced bacon over medium heat until it's perfectly crispy. This usually takes about 8-10 minutes.
   2. Sauté Onions: Using a slotted spoon, remove the crispy bacon bits from the skillet and set them aside, leaving about 2-3 tablespoons of bacon fat in the pan. Add the finely chopped onion to the same skillet with the bacon fat. Sauté over medium-low heat until the onions are softened and beautifully translucent, about 5-7 minutes. Avoid browning them too much; we want sweetness, not bitterness. Visual cue: Onions will be soft and clear, not browned.
3. Combine the Batter:
   1. Mix Wet Ingredients: In a large mixing bowl, whisk together the beaten eggs, milk (or cream), salt, and pepper until well combined. If using, stir in the dried marjoram now.
   2. Add Solids: Add the drained grated potatoes, the cooked (and slightly cooled) bacon bits, and the sautéed onions to the wet mixture.
   3. Balance Moisture: Give everything a good stir until all ingredients are evenly distributed. The mixture should be thick but still pourable. If it seems too dry, add another splash of milk; if it seems too wet (which shouldn't happen if you drained the potatoes well), you can add a tablespoon or two of flour or potato starch to help bind it, though this is rarely needed with proper draining.
4. Bake Perfectly:
   1. Preheat Oven: Preheat your oven to 350°F (175°C). Lightly grease a 9x13 inch baking dish (or a similar sized casserole dish).
   2. Transfer Batter: Pour the Kugelis batter into the prepared baking dish, spreading it evenly. If using, tuck a bay leaf or two into the mixture for extra flavor during baking.
   3. Cover and Bake: Cover the baking dish tightly with aluminum foil. Bake for 1 hour. This initial covered bake allows the potatoes to cook through and become tender without drying out.
   4. Uncover and Crisp: After 1 hour, remove the foil. Increase the oven temperature to 375°F (190°C). Continue baking uncovered for another 45-60 minutes, or until the top is a beautiful golden brown and crispy, and a knife inserted into the center comes out clean. An oven thermometer can help ensure your oven maintains the correct temperature for even cooking. Visual cue: The top should have a deep golden, almost reddish-brown crust.
   5. Rest: Once baked, remove the Kugelis from the oven and let it rest for 10-15 minutes before slicing and serving. This allows it to set up properly and makes for cleaner slices.
