How to Make Cheesy Mashed Potato Cakes Step by Step
Step 1: Mix the Ingredients
In a large mixing bowl, combine the mashed potatoes, flour, Parmesan cheese, chopped chives, and sour cream. Season with sea salt to taste and mix until evenly combined.
Step 2: Add the Eggs
Pour the beaten eggs into the potato mixture and stir thoroughly until a cohesive dough-like mixture forms.
Step 3: Shape the Potato Cakes
Using your hands or a scoop, form the mixture into small, flat cakes about ½-inch thick. Place them on a plate or baking sheet while you prepare the skillet.
Step 4: Heat the Skillet
Lightly oil a large skillet and heat it over medium heat until hot but not smoking.
Step 5: Cook Until Golden
Carefully place the potato cakes into the skillet, leaving a little space between each one. Cook for 3 to 4 minutes per side until beautifully golden brown and crispy.
Step 6: Serve and Enjoy
Transfer the cooked potato cakes to a serving plate and garnish with extra chopped chives if desired. Serve warm while the outside is crispy and the inside remains creamy.
Expert Tips
- Cold mashed potatoes are easier to shape into cakes.
- If the mixture feels too soft, add a little extra flour.
- Don't overcrowd the skillet to ensure even browning.
- Use freshly grated Parmesan for the best flavor.
- Allow the cakes to cook undisturbed for a crisp golden crust.
How to Store and Reheat Them
Store leftover potato cakes in an airtight container in the refrigerator for up to 3 days.
To reheat, place them in a skillet over medium heat for a few minutes per side or warm them in a 350°F oven until heated through.
Avoid microwaving if possible, as it can soften the crispy exterior.
You can also freeze cooked potato cakes for up to 2 months. Thaw overnight before reheating.
What to Serve With Them
These potato cakes pair wonderfully with:
- Sour cream
- Ranch dressing
- Garlic aioli
- Fried eggs
- Grilled chicken
- Roasted vegetables
- Fresh green salad
- Smoked salmon
