Grate the Potatoes: Peel and grate 3 medium potatoes using a box grater or food processor. Once grated, place the potatoes in a clean kitchen towel or cheesecloth and squeeze out as much excess moisture as possible. Removing excess water will ensure the patties turn out crispy and golden.

Chop the Onion and Garlic: Finely chop the onion and mince 2 cloves of garlic. Set them aside to be added to the beef mixture later.

Combine the Ingredients: In a large mixing bowl, combine the 500g of ground beef with the grated potatoes, chopped onion, and minced garlic. Add 1 tablespoon of mayonnaise, 30g of melted butter, 1 teaspoon of salt, 1 teaspoon of paprika, and black pepper to taste.

Add the Fresh Herbs: Finely chop a handful of parsley and add it to the beef mixture for a fresh, herby flavor. Use your hands or a spoon to mix all the ingredients thoroughly until well combined.

Form the Patties: Using your hands, shape the beef and potato mixture into round patties. Each patty should be about the size of the palm of your hand and around 1-1.5 cm thick. You should be able to make about 8-10 patties from this recipe.

Heat the Oil: Heat about 2-3 tablespoons of olive oil in a large frying pan over medium heat. You want enough oil to cover the bottom of the pan but not so much that the patties are submerged.

Fry the Patties: Once the oil is hot, carefully place the patties into the pan, being careful not to overcrowd it. Fry the patties for about 4-5 minutes on each side, or until they are golden brown and crispy on the outside. The internal temperature of the patties should reach 160°F (71°C) to ensure the beef is fully cooked.

Drain the Patties: After frying, transfer the patties to a plate lined with paper towels to drain any excess oil. Repeat the process with the remaining patties, adding more oil to the pan as needed.

Serve Hot: These crispy beef and potato patties are best served hot. You can garnish them with a bit of fresh parsley and serve them with a dipping sauce like ketchup, garlic aioli, or sour cream. They also pair well with a side salad, steamed vegetables, or roasted potatoes.
