Essential Ingredients for Perfect Homemade Mashed Potato Cakes

Let’s take a closer look at a few of the key ingredients that make these crispy mashed potato cakes so delicious:

Mashed Potatoes: The star of the show. Ideally, use leftover mashed potatoes that are seasoned but not overly buttery to form sturdy cakes. If they’re too cold, let them come to room temperature for easier mixing.
Onion: Minced onion adds a lovely pop of flavor to the cakes. Fresh onions work best, but in a pinch, you can substitute dried minced onion or even a dash of onion powder.
Egg: Acts as a binder to hold the cakes together. Be sure to whisk it before adding to the potato mixture for even distribution.
Flour: Helps give the cakes structure while keeping them light. Gluten-free flour works well here for anyone with dietary constraints.

Homemade Mashed Potato Cakes Ingredients

½ cup Canola Oil
2 cups Leftover Cooked Mashed Potatoes (room temperature)
1 tablespoon Minced Onion
1 Egg
1 tablespoon All-purpose Flour
1 teaspoon Dried Parsley
½ teaspoon Salt
⅛ teaspoon Black Pepper

How to Make Homemade Mashed Potato Cakes

Preheat a large skillet with half the oil over medium heat. You want the oil hot but not smoking.
In a large mixing bowl, combine the mashed potatoes, minced onion, whisked egg, flour, parsley, salt, and pepper. Mix until smooth and well blended.
Using an ice cream scoop or large spoon, scoop out portions of the mixture and carefully place them into the hot oil.
Flatten each scoop gently with a spatula into a patty shape, ensuring the cakes don’t touch each other in the pan.
Cook 2–4 cakes at a time for about 2–4 minutes on each side, or until golden brown and crisp.
Transfer the cooked cakes to a plate lined with paper towels to drain excess oil.
Repeat the process, adding more oil as needed, until all the potato mixture is used.
Serve the cakes warm with your favorite toppings such as sour cream or applesauce.

Expert Tips for the Best Homemade Mashed Potato Cakes

Use room temperature potatoes: Cold mashed potatoes can be tough to mix and shape. Let them sit out for 30 minutes or gently reheat until just warm to the touch.
Don’t overcrowd the pan: Fry 2–4 cakes at a time depending on the size of your skillet. Giving each cake room ensures even browning.
Avoid over-mixing: Mix just until the ingredients are combined to prevent the cakes from becoming gummy.
Keep the oil temperature steady: Too hot, and the cakes will burn; too cool, and they’ll absorb more oil than necessary.
Storage: Store leftovers in an airtight container in the fridge for up to three days. Reheat in a skillet for a crisp finish, or pop them in the oven at 350°F for 8–10 minutes.

Delicious Homemade Mashed Potato Cakes Variations

Cheesy potato cakes: Mix in shredded cheddar cheese or Parmesan for extra flavor.
Spicy kick: Add a pinch of cayenne pepper or chopped jalapeños for a hint of heat.
Herbaceous twist: Swap dried parsley for fresh chives, dill, or rosemary to change up the flavor.
Gluten-free option: Replace the flour with gluten-free all-purpose flour or breadcrumbs.

Homemade Mashed Potato Cakes FAQs

Can I make these with instant mashed potatoes?

Yes, but try to make the instant mashed potatoes thicker than usual so they hold together better when forming the cakes.

How do I make the cakes extra crispy?

Ensure your oil is hot before frying, and press the cakes slightly flatter to increase the crispy surface area.

What can I serve with these?

Classic sides like sour cream, applesauce, or even a dollop of Greek yogurt pair beautifully. They also make a great side dish for roast chicken or beef!

Can I freeze mashed potato cakes?

Yes! Freeze the cakes after frying. When ready to enjoy, bake them straight from frozen at 400°F until heated through and crispy.
