Ingredients

  • 1 egg
  • 1 Tbsp. flour
  • 1 small onion

Instructions

  1. Mix the egg with the mashed potatoes.
  2. Add the chopped onion and blend well.
  3. Stir in the flour until the mixture is well combined.
  4. Spoon the mixture into flour and roll to coat both sides.
  5. Drop the coated patties into hot oil in a skillet and fry on both sides until golden brown.
  6. Optionally, add leftover meat pieces to the mixture before frying.

Tips & Substitutions

For extra flavor, consider adding garlic powder or herbs like parsley or chives to the potato mixture. If you're short on flour, breadcrumbs can be a great substitute for coating the patties. Be sure to keep the oil hot but not smoking to achieve a perfectly crispy exterior while keeping the insides deliciously creamy. These patties can also work well with leftover bacon or ham for a heartier meal.

Serving Suggestions

Serve these patties hot, garnished with sour cream or your favorite dipping sauce. They pair wonderfully with a side salad or steamed vegetables, and for a complete meal, consider serving them alongside Hungarian Sweet-Sour Carrots. For an extra touch, top with freshly chopped herbs or a sprinkle of cheese just before serving.

Storage & Reheating

Store any leftover mashed potato patties in an airtight container in the refrigerator for up to 3 days. To reheat, place them in a skillet over medium heat until warmed through and crispy, or use an air fryer for about 5-7 minutes at 350°F for a quick and easy reheating option.

Frequently Asked Questions

Can I use instant mashed potatoes instead of fresh?

Yes, you can use instant mashed potatoes, but the texture may differ slightly. Be sure to follow the package instructions to prepare them before mixing with the egg and onion. Instant varieties can yield a denser patty, so adjust the flour accordingly to achieve the desired consistency.

What kind of oil is best for frying these patties?

For frying, use oils with a high smoke point like vegetable oil, canola oil, or grapeseed oil. These oils will help achieve a crispy texture without burning. Avoid using olive oil for deep frying, as it has a lower smoke point and may impart unwanted flavors.

Can I freeze the patties before frying?

Absolutely! To freeze, place the formed patties on a baking sheet lined with parchment paper and freeze them until solid. Once frozen, transfer them to a freezer bag. They can be fried directly from frozen; just add a few extra minutes to the cooking time for even heat distribution.
