  • 2 large eggs , beaten (or flax eggs for vegan option)
  • onion , finely chopped (or shallots for milder sweetness)
  • red bell pepper , finely chopped (or green pepper for sharper bite)
  • 100g (1 cup) shredded mozzarella cheese (or cheddar, Gouda, or vegan cheese)
  • 1 tbsp Parmesan cheese , grated (optional – or nutritional yeast for vegan umami boost)
  • 1–2 tbsp olive oil (or melted butter for richer crust)
  • 1 tsp salt (adjust to taste – or use sea salt flakes for texture)
  • Freshly ground black pepper , to taste
  • A pinch of nutmeg (enhances dairy richness – optional but recommended)
  • A pinch of dried marjoram (or thyme/oregano for shortcut herbs)

Instructions:

Step 1: Preheat Oven & Prep Dish

Preheat oven to 375°F (190°C) .

Grease a 9×13-inch baking dish or cast iron skillet with olive oil or butter—set aside.


Step 2: Grate & Dry Potatoes

Peel potatoes and grate them using a box grater or food processor.

Place grated potatoes in a clean kitchen towel or cheesecloth and squeeze out excess moisture.

Tip: Removing moisture helps achieve crispness instead of sogginess—don’t skip this step!
