Ingredients for arby's potato cakes copycat
Eight simple ingredients transform into Arby's signature crispy, tangy potato cakes at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 2 lbs | Medium size, peeled and cut |
| All-Purpose Flour 🌾 | ½ cup | For binding potato mixture |
| Fine Cornmeal 🌽 | ½ cup | Yellow or white, not self-rising |
| Baking Powder 🧂 | 1 tbsp | For lightness in texture |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Vegetable Oil 🫒 | 1 cup | For frying, high smoke point |
| White Vinegar 🍶 | ½ cup | For tangy dipping sauce |
| Water 💧 | ½ cup | For dipping sauce |

The potatoes are everything here—russets are ideal for their starch content, but Yukon Golds work too (they'll be slightly creamier). Peeled and cut into 1-inch cubes, they absorb the cornmeal crust perfectly. Most grocery stores carry russets, but if you're at Whole Foods or a specialty market, ask for organic russets—they're less waxy and taste better. The cornmeal is non-negotiable for that signature crunch; Bob's Red Mill is my go-to brand, but any fine cornmeal will do. Pro tip: Soak the cut potatoes in cold water for 10 minutes after peeling to remove excess starch, which helps the crust adhere better.
No cornmeal? Crushed cornflakes in a pinch (pulse them in a blender or food processor), but they won't be quite as crispy. Short on baking powder? 1/4 tsp cream of tartar plus 1/4 tsp baking soda works as a substitute. The vinegar dip is where the magic happens—white vinegar gives that classic tang, but apple cider vinegar adds a fruity twist. For the dipping sauce, Trader Joe's sells pre-made vinegar mixes that cut prep time in half. If you're making a big batch, double the sauce ingredients—trust me, you'll want seconds. The butter in the dip isn't just for flavor; it balances the acidity and makes every bite richer.
These potato cakes reheat beautifully—pop them in a 350°F oven for 10-15 minutes to restore crispiness. Store leftovers in an airtight container for 3-4 days, but honestly, they're best fresh. The dipping sauce keeps for 1 week in the fridge, though I always make extra because it disappears fast. For game day or parties, fry the cakes ahead and reheat before serving. They freeze well too—just lay them flat on a tray to freeze, then transfer to a bag for up to 3 months. The cornmeal crust gets extra crispy after freezing, so it's worth it for leftovers.
Why You'll Love This Recipe
- No Peel, No Stress: I swear by this trick—just grate those Russets raw, no peeling, no fuss. The baking powder does the magic, fluffing them up while keeping that golden crust intact. (Yes, even when my hands get tired halfway through.)
- Crispy-Creamy Magic: That cornmeal crust? Chef’s kiss. It’s got this perfect crunch on the outside while staying pillowy inside—just like the ones I’d drive 10 minutes for. Honestly, the flour and baking powder combo makes them light, not dense.
- Game for Any Meal: Slap these on a plate with a side salad for lunch, turn them into nachos with cheese sauce, or serve them as a snack with BBQ dip. My kids grab them straight from the pan—no judgment here.
- Pantry Staple Power: Five ingredients, zero specialty items. The potatoes and flour alone are cheap, and the cornmeal stretches it further. Plus, they reheat like a dream—microwave or oven, no soggy edges. My wallet and leftovers thank me.
Step-by-step instructions for Arby's potato cakes copycat recipe
Here's how to make those iconic crispy potato cakes with the perfect vinegar dipping sauce.
Prepare the Potato Mixture
Start by grating the 2 lbs russet potatoes using the large holes of a box grater. Place the grated potatoes in a clean kitchen towel and squeeze out all the excess moisture. This step is crucial—wet potatoes won't crisp up properly. I like to work in batches, squeezing each handful until it's just barely damp to the touch, not wet.
In a large mixing bowl, combine the grated potatoes with the 0.5 cup all-purpose flour, 0.5 cup fine cornmeal, 1 tbsp baking powder, 1.5 tsp salt, 0.5 tsp black pepper, 0.5 tsp garlic powder, and 0.5 tsp onion powder. Mix gently with a wooden spoon just until everything is evenly distributed. Don't overmix—you're looking for a rough, shaggy texture that holds together when pressed. The mixture should be thick enough to form balls without sticking to your hands.
Form and Fry the Potato Cakes
Heat 1 cup vegetable oil in a large skillet over medium-high heat until it reaches 350°F. You can test the temperature by dropping a small piece of potato mixture in—it should sizzle and float immediately. If it sinks or bubbles too vigorously, the oil isn't hot enough.
Using a tablespoon measure, scoop portions of the potato mixture and gently press them into 1-inch thick patties on parchment paper. Place them on a wire rack to firm up for 5 minutes—this prevents them from falling apart when you fry them. Working in batches, carefully slide the potato cakes into the hot oil. Fry for 3-4 minutes per side until they're golden brown and deeply crispy. You'll know they're done when they release easily from the pan and have a crisp exterior with a soft, fluffy interior. Transfer to a paper towel-lined plate to drain excess oil.
Make the Vinegar Dipping Sauce
While the potato cakes are frying, make the tangy dipping sauce. In a small saucepan, combine the 0.5 cup white vinegar, 0.5 cup water, 1 tbsp granulated sugar, and 2 tbsp butter. Bring to a gentle simmer over medium heat, stirring until the butter melts completely and the sugar dissolves. Let it simmer for 2-3 minutes until slightly thickened and the flavors meld together. The sauce should coat the back of a spoon and have a glossy sheen.
Taste and adjust the seasoning if needed—you might want to add a pinch more salt or a splash more vinegar to suit your preference. Keep the sauce warm over low heat until ready to serve. The perfect sauce should be slightly sweet, tangy, and rich enough to complement the crispy potato cakes.
Serve Immediately for Maximum Crispiness
Serve the potato cakes hot with the warm vinegar dipping sauce on the side. The key to serving these right is timing—they're best enjoyed immediately while still crispy. If you need to hold them for a few minutes, keep them warm in a 200°F oven on a wire rack to prevent sogginess.
For an extra touch, sprinkle a pinch of black pepper on top of each cake right before serving. The contrast of the crispy, golden exterior with the soft, fluffy interior and the tangy vinegar sauce makes this dish irresistibly addictive. You'll love how these copycat potato cakes capture the exact texture and flavor of the original—crispy on the outside, tender on the inside, with that perfect vinegar kick.
Pro Tips For Making Arby'S Potato Cakes Copycat
- GRATE WHILE COLD: Russets lose structure fast—grate them right after peeling while still chilled from the fridge. The starch stays tighter, and your cakes won’t turn into mush when mixing. (I learned this the hard way after a batch of sad, gluey batter.)
- WEIGH THE FLOUR: Scooping flour from the bag packs in air—use a kitchen scale for 1 cup (120g) of all-purpose flour. Too much flour makes these dense; too little means they’ll fall apart. (Yes, even if you’re impatient like me, grab the scale.)
- PRESS HARD, FLATTEN EVEN: Use a fork to press the batter into the pan—apply firm, even pressure so the edges are crisp while the center stays tender. Uneven pressing = uneven cooking. (Think of it like making pancakes: consistent thickness = consistent results.)
- COOK IN BATCHES: Skip the urge to crowd the pan—cook 2-3 cakes at a time over medium-high heat. Overfilling steams them instead of crisping, and they’ll stick like glue. (Your future self will thank you for the extra 2 minutes of waiting.)
Storing and reheating this arby's potato cakes copycat
Refrigerator Storage
Store leftover potato cakes in an airtight container for up to 3-4 days—just like Arby's would, if they did leftovers! Keep them in a single layer to maintain crispiness, and separate the dipping sauce to prevent sogginess.
I like using glass containers with tight-sealing lids because they keep moisture out better than plastic. The cornmeal crust stays crunchy if you let them cool completely before storing. 💫
Freezer Prep
For long-term storage, freeze the potato cakes on a wire rack-lined tray for 1 hour to prevent sticking, then transfer to a freezer bag with parchment paper between layers. They'll keep for up to 3 months—the cornmeal crust gets even crispier after freezing, which is a bonus!
Thaw overnight in the fridge before reheating. Never microwave from frozen; that's a one-way ticket to mushville. ❄️
Oven Reheating
To restore that golden crispiness, preheat your oven to 350°F and place the frozen or refrigerated cakes on a wire rack over a baking sheet. Bake for 10-12 minutes until heated through and crispy again.
For extra crunch, brush the tops with a little melted butter before baking. The vinegar sauce reheats beautifully too—just warm it in a small saucepan over low heat for 2-3 minutes. 🔥
Air Fryer Option
If you're short on time, the air fryer is your best friend. Preheat to 375°F and cook frozen cakes for 4-5 minutes, shaking halfway, until crispy. For refrigerated cakes, increase to 5-6 minutes.
This method works best for small batches—don't overcrowd the basket, or they'll lose their crunch. The air fryer preserves that Arby's-style texture better than any other method. ⚡
Dipping Sauce Refresh
Reheat the vinegar sauce separately in a small saucepan over medium-low heat, stirring until warm. If it thickens too much, thin it with 1-2 teaspoons of water or vinegar.
For extra richness, stir in 1 extra tablespoon of butter while reheating. The sauce should be glossy and tangy—just like the first time you made it. 💡
Pro Tips for Leftovers
If your potato cakes lose crispiness overnight, pop them back in the air fryer at 400°F for 3-4 minutes to revive them. For the sauce, store it separately in a small jar with a lid to keep it fresh.
I always double the sauce recipe because it disappears faster than the potato cakes! The secret to perfect leftovers is proper storage and reheating methods—don't skip the wire rack or you'll end up with soggy disappointment. 💪

Frequently asked questions about Arby's-style potato cakes
Why does my potato cake batter turn out too wet or sticky?
Excess moisture is the #1 reason for sticky batter. Always squeeze grated potatoes thoroughly in a clean towel until they're just barely damp—not wet. If your mixture feels too loose, add 1-2 extra tablespoons of cornmeal to absorb moisture. The key is working in small batches to wring out every drop of liquid before mixing.
Can I make these potato cakes ahead of time?
Fry them up to 3 days ahead and store in an airtight container at room temperature. For longer storage, freeze them on a wire rack for 1 hour before transferring to a bag. The cornmeal crust stays crispy when reheated properly—just pop them in a 350°F oven for 10 minutes or use an air fryer at 375°F for 4-5 minutes.
What's the secret to getting that perfect crispy crust?
The two-step frying process is everything! First, par-cook at 350°F for 3-4 minutes per side to set the shape. Then increase heat to medium-high and crisp for 1-2 extra minutes until golden brown. The cornmeal needs hot oil to crisp properly—never overcrowd the pan or the temperature will drop. A wire rack helps maintain crispiness during cooking.
Can I use sweet potatoes instead of russets?
While possible, russet potatoes are ideal for their high starch content and neutral flavor. Sweet potatoes will give you a slightly sweeter, denser cake with less crispiness. If you must use them, grate them extra fine and increase cornmeal to 2/3 cup to compensate for the moisture difference. The vinegar dip will still balance the sweetness beautifully.
How do I adjust the vinegar dipping sauce for picky eaters?
For less tang, reduce vinegar to 1/4 cup and add 1 extra tablespoon of sugar. For more richness, increase butter to 3 tablespoons. Kids often prefer a milder version—try mixing equal parts sauce with ketchup or ranch dressing. The sauce keeps well in the fridge for 1 week**, so you can always adjust it later if needed.
