Chopped scallions: Provide a mild onion flavor and a touch of crunch.
Fresh parsley: Adds a burst of fresh, herbaceous brightness.
Large egg: Acts as a binder, keeping the patties together.
Onion powder: For a subtle depth of savory flavor.
Cayenne pepper: A pinch gives a gentle, warming kick without overpowering.
All-purpose flour: Helps absorb moisture and bind the mixture without weighing it down.

Make It Your Way

One of the best things about this Savory Potato Cakes with Cheddar and Parsley Recipe is how easy it is to customize. Whether you want to swap in your favorite herbs, adjust the spice level, or make it fit a special diet, these cakes are super adaptable and always delicious.

Try Adding Bacon or Ham: If you enjoy a bit of smoky flavor, toss in some crispy cooked bacon bits or finely diced ham with the potato mixture. It adds a wonderful savory punch that takes these cakes from light to hearty.
Make It Vegan: Use a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) instead of the regular egg, and swap cheddar for a plant-based cheese alternative. Be sure to check your panko breadcrumbs are vegan-friendly too!
Play with Herbs and Spices: Fresh dill or chives can be swapped in for parsley and scallions for a fresh twist. And if you like things spicier, add a pinch of smoked paprika or a bit more cayenne pepper for a subtle heat that perks up the flavor.
Seasonal Veggies: Grated zucchini, finely chopped roasted red peppers, or even corn kernels stirred into the batter bring seasonal freshness and a pop of color to the cakes.

Step-by-Step: How I Make Savory Potato Cakes with Cheddar and Parsley Recipe

A large clear glass bowl sits on a white marbled surface, filled with a thick mixture that has three main visible layers: creamy off-white batter, bright orange shredded pieces, and finely chopped green herbs spread throughout. A woman's hand holds the bowl steady while another woman's hand stirs the mixture with a white spatula that has a wooden handle. Around the bowl, there are white bowls, one showing flour and another with yellow shredded ingredients, all on the same white marbled surface. Photo taken with an iphone --ar 2:3 --v 7

Step 1: Gather and mix your ingredients into a flavorful batter

Start by combining 2 cups of leftover mashed potatoes with ⅔ cup grated sharp cheddar cheese, 3 chopped scallions, ¼ cup fresh parsley, 1 large egg, ½ teaspoon onion powder, and a pinch of cayenne pepper in a large bowl. Stir them together until everything is evenly mixed. Then gently fold in ½ cup all-purpose flour until just combined. Be careful not to overmix the batter—that helps keep the cakes tender and light. At this stage, the mixture should feel slightly sticky but hold together well.

Step 2: Shape the patties and coat in panko breadcrumbs

Next, pour ¾ cup panko breadcrumbs into a shallow dish for coating. Using a ¼-cup measuring cup, scoop the potato mixture and form it gently with your hands into thick patties. If the mixture is too sticky to work with, pop it in the fridge for 20 to 30 minutes to firm up—this really helps the shaping process. Once shaped, coat each patty thoroughly in the panko, then gently press them down to about ½-inch thickness. This thickness ensures a perfectly crisp crust and a warm, gooey center.

Step 3: Fry until golden and melty

Heat a cast-iron skillet over medium heat, then add enough avocado oil to coat the bottom. When the oil shimmers, carefully add a batch of the potato cakes—don’t overcrowd the pan. Press lightly with a spatula to help the bottoms make full contact, which gives you that perfect golden crust. Cook for 2 to 3 minutes on each side until both sides are beautifully browned and the cheddar inside is melted and oozing. If you're making multiple batches, keep the cooked cakes warm in a low oven.

Step 4: Garnish and serve immediately

Transfer the cooked potato cakes to a plate lined with paper towels to soak up any excess oil. Sprinkle with extra chopped scallions for a fresh, oniony crunch. Serve them warm alongside a dollop of cool, tangy sour cream for dipping. These cakes shine as a side dish or a light lunch when paired with a crisp green salad.

Top Tip

Mastering the Savory Potato Cakes with Cheddar and Parsley Recipe is all about getting that perfect balance of crispy exterior and melty, flavorful inside. Here are some tips I've picked up from making these over and over to help you get it just right.

Use leftover mashed potatoes: Freshly made mashed potatoes tend to be too soft, which makes shaping the cakes tricky. Leftovers have firmer texture and bind much easier without adding extra flour.
Chill sticky batter: If your mixture feels too sticky to handle, pop it in the fridge for 20-30 minutes before shaping. It firms up beautifully and makes coating with panko crumbs much easier.
Preheat the oil properly: Make sure your skillet and avocado oil are hot enough before adding the cakes. This helps form a crispy crust quickly and prevents the cakes from soaking up too much oil.
Don’t overcrowd the pan: Cooking in batches ensures each cake has enough room to crisp up nicely without steaming. It’s worth the little extra time!

Garnishes

These potato cakes shine with a simple garnish of extra chopped scallions for a fresh crunch and mild onion flavor. A dollop of cool, tangy sour cream on the side complements the warm, cheesy cakes perfectly. For a little extra zing, sprinkle on a pinch of smoked paprika or a squeeze of fresh lemon juice just before serving.

Side Dishes

Because these savory potato cakes are rich and hearty, they pair wonderfully with light, crisp sides. Try a fresh green salad tossed with a lemon vinaigrette, steamed seasonal vegetables, or simple roasted carrots. They’re also a delightful side to grilled chicken, pan-seared fish, or roasted pork—adding that satisfying crispy, cheesy element to your meal.

Make Ahead and Storage

Storing Leftovers

Once cooled, store your leftover potato cakes in an airtight container in the refrigerator. They’ll keep well for up to 3 days—perfect for quick lunches or snacks.

Freezing

If you want to make a big batch ahead of time, these cakes freeze beautifully. After shaping and coating, arrange them on a baking sheet so they aren’t touching and freeze until solid. Then transfer to a freezer-safe bag or container. They’ll keep for up to 2 months frozen.

Reheating

Reheat chilled or frozen potato cakes in a preheated skillet over medium heat with a little avocado oil, cooking 3–4 minutes per side until warmed through and crisp again. You can also pop them in a 350°F (175°C) oven for about 10 minutes if you prefer baking.

Frequently Asked Questions:

Can I make these potato cakes gluten-free?

Absolutely! Substitute the all-purpose flour and panko breadcrumbs with gluten-free versions, such as almond flour and gluten-free panko or crushed gluten-free crackers. The texture might differ slightly, but they’ll still be delicious.

What if I don't have leftover mashed potatoes?

You can make mashed potatoes fresh, but be cautious not to make them too soft or watery. Use starchy potatoes like Russets and mash them until smooth but firm. You may need to add a little more flour to help the cakes hold their shape.

Can I bake the potato cakes instead of frying?

Yes! Preheat your oven to 400°F (205°C). Place the coated cakes on a baking sheet lined with parchment and lightly spray or drizzle with oil. Bake for about 15-20 minutes, flipping halfway through until golden and crispy.

How can I make these potato cakes spicier?

For an extra kick, increase the cayenne pepper a bit or serve with a spicy dipping sauce like chipotle mayo or sriracha mixed with sour cream. Fresh jalapeño or red chili flakes folded into the batter also work great.
