Description

Crispy onion and cheddar mashed potato cakes made from creamy mashed potatoes mixed with sharp cheddar and sautéed onions, then pan-fried until golden and crunchy on the outside.


Ingredients

  • 3 cups mashed potatoes (cold works best)
  • 1 cup shredded sharp cheddar cheese
  • 1 small onion, finely diced
  • 2 tbsp butter
  • 1/4 cup all-purpose flour
  • 1 large egg
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 1/4 tsp garlic powder
  • 1/4 cup chopped green onions or chives
  • 1/2 cup breadcrumbs (optional for coating)
  • 2–3 tbsp vegetable oil or olive oil for frying


Instructions

  1. Heat butter in a skillet over medium heat. Add the diced onion and cook for 4–5 minutes until soft and lightly golden. Remove from heat and allow to cool slightly.
  2. In a large bowl, combine mashed potatoes, cheddar cheese, cooked onions, flour, egg, salt, pepper, garlic powder, and green onions. Mix until well combined.
  3. If the mixture is too soft, add a little more flour until it can hold its shape.
  4. Form the mixture into small patties about 2–3 inches wide.
  5. Optional: Lightly coat each potato cake in breadcrumbs for extra crispiness.
  6. Heat oil in a large skillet over medium heat.
  7. Place the potato cakes in the skillet and cook for 3–4 minutes per side until golden brown and crispy.
  8. Transfer to a paper towel-lined plate to drain excess oil.
  9. Serve warm, optionally topped with sour cream or extra chopped green onions.

Notes

  • Cold leftover mashed potatoes work best for shaping the cakes.
  • Add cooked bacon bits for extra flavor if desired.
  • If the mixture feels sticky, chill it for 20 minutes before forming patties.
  • These cakes can be baked at 400°F (200°C) for about 20 minutes instead of frying.
  • Store leftovers in the refrigerator for up to 3 days and reheat in a skillet for best texture.
