Serve them as a snack with ranch, a side with burgers, or even as a breakfast hash. The versatility of these potato cakes makes them a game-changer for any meal. Let’s get started on recreating this iconic dish step by step.

Ingredients for arby's potato cakes copycat

Twelve ingredients transform humble potatoes into iconic Arby's-style potato cakes with signature tangy crunch and fluffy centers.

The potatoes are the foundation—russets or Yukon golds yield the perfect starchy texture. Peel them uniformly for even cooking, then cut into precise 1-inch cubes to ensure consistent frying. For the brine, white vinegar and Diamond Crystal kosher salt create that signature sharpness; store-bought vinegar works, but distilled vinegar delivers the cleanest tang. The secret lies in the 1:3 vinegar-to-water ratio—don’t skimp on the salt, or the flavor will fall flat. Soak the potatoes for exactly 30 minutes to absorb the brine without over-saturating. Most grocery stores carry russet potatoes in the produce section, but specialty markets like Whole Foods often have Yukon golds with superior texture.

No buttermilk? Substitute 0.5 cup milk plus 0.5 tsp vinegar, but let it sit for 5 minutes to curdle properly. The baking powder and baking soda are non-negotiable for that signature fluffiness—aluminum-free versions ensure consistent rise without metallic aftertaste. For the oil, vegetable or canola oil works best due to its high smoke point, but peanut oil adds a subtle nutty note if you’re feeling adventurous. The double-fry technique requires two separate batches of oil: the first at 350°F for 4 minutes, the second at 375°F for 3 minutes. If your potatoes brown too quickly, reduce the heat by 25°F. For extra crispiness, pat them dry with paper towels before the second fry—this step is critical for that restaurant-quality crunch.

Potato cakes reheat beautifully—350°F for 10-12 minutes restores their crispiness. Store leftovers in an airtight container for up to 3 days, but they’re best enjoyed fresh. For meal prep, freeze them unfrosted on a tray for 1 hour, then transfer to a bag for up to 3 months. To serve, dust with extra garlic powder and black pepper straight from the fryer. Pair with ranch dressing or Arby's signature sauce for the full experience. The vinegar brine keeps them tangy even when reheated, making them ideal for game day or late-night snacks.

Step-by-step instructions for Arby's potato cakes copycat recipe

Here's the precise method to recreate Arby's signature potato cakes at home—crispy exteriors with fluffy, pink centers.

In a large bowl, combine the 2.5 lbs russet potatoes (cut into 1-inch cubes) with the 0.5 cup white vinegar and 1.5 tbsp diamond crystal kosher salt. Toss thoroughly until every potato cube is evenly coated. This step is critical—the vinegar tenderizes the potatoes while the salt enhances flavor and promotes crispiness.

Transfer the potato mixture to a resealable plastic bag and refrigerate for at least 1 hour, though 2 hours yields the best texture. The potatoes should absorb the brine completely, becoming slightly translucent at the edges. This soaking period ensures the cakes will hold together during frying and develop that signature tangy crunch.

In a medium bowl, whisk together the 1 cup all-purpose flour, 1 tbsp baking powder, 0.5 tsp baking soda, 0.5 tsp granulated sugar, 0.5 tsp freshly ground black pepper, 0.5 tsp garlic powder, and 0.5 tsp onion powder. Sift the dry ingredients to eliminate any lumps, which prevents dense cakes. Set aside.

In a separate bowl, beat the 1 whole large egg until frothy, then whisk in the 0.5 cup buttermilk until smooth. Gradually pour the wet mixture into the dry ingredients while stirring gently with a spatula. The batter should be thick but pourable—like heavy pancake batter. Avoid overmixing, as this develops gluten and makes the cakes tough.

After soaking, drain the potatoes in a colander and let them sit for 5 minutes to release excess moisture. This step is often skipped but makes a noticeable difference in crispiness. Working in batches, press the potatoes into the batter, ensuring each cube is fully coated. Let them sit for 2 minutes to allow the batter to adhere.

Heat 1.5 cups vegetable oil in a deep skillet or Dutch oven over medium heat until it reaches 350°F (use a thermometer for accuracy). The oil should shimmer but not smoke excessively. Fry the potatoes in batches, turning occasionally, for 4-5 minutes per side until golden brown and crispy. Avoid overcrowding the pan, as this lowers the oil temperature and results in greasy cakes.

Transfer the fried potato cakes to a wire rack or paper towels to drain excess oil. They should be deep golden brown with a crisp exterior. Serve immediately while still hot, as they lose crispiness as they cool. For extra authenticity, sprinkle with additional diamond crystal kosher salt and serve with a side of tangy dipping sauce.

Real talk: The secret to these potato cakes lies in the vinegar brine and precise frying temperature. If the oil isn't hot enough, the cakes will absorb too much oil and turn greasy. If they brown too quickly, reduce the heat slightly—you're aiming for even cooking without burning. Enjoy your copycat Arby's potato cakes with that signature vinegar-kissed crunch!

Dietary considerations for this arby's potato cakes copycat

Gluten-Free Adaptation

For a gluten-free version, replace the 1 cup all-purpose flour with a 1:1 gluten-free flour blend like Bob’s Red Mill 1-to-1. Add 1 tbsp xanthan gum to mimic gluten’s binding properties.

The vinegar brine and frying technique remain the same, but gluten-free batters often require slightly lower oil temperatures (325°F) to prevent burning. Test one cake first—they may need 1-2 extra minutes of frying time. 🌾

Dairy-Free Version

Swap the buttermilk for unsweetened almond milk mixed with 0.5 tsp vinegar (let it curdle for 5 minutes). Use dairy-free butter in the batter if desired, though the original recipe’s richness comes from the buttermilk.

The texture remains fluffy, but the flavor will be subtly milder. For extra tang, add 0.5 tsp apple cider vinegar to the batter. 🥛

Lower-Carb Option

Reduce the potatoes to 1.5 lbs and add 0.5 cup grated zucchini or cauliflower rice to the batter for bulk. Use almond flour instead of regular flour (mix with 0.25 cup gluten-free flour for binding).

The cakes will be lighter but still crispy. Keep the vinegar brine—it’s the star of the flavor! 🥦

Allergen-Friendly Notes

Check your Diamond Crystal kosher salt for iodine—some brands contain anti-caking agents that may trigger allergies. For egg-free versions, replace the 1 egg with 0.5 cup aquafaba (chickpea brine) or 1 tbsp ground flaxseed + 3 tbsp water.

Always test for cross-contamination if using shared fryers or utensils. Safety first! 💡

Vegan Substitutions

Use flax eggs (1 tbsp ground flax + 3 tbsp water per egg) and replace buttermilk with unsweetened soy milk + 0.5 tsp vinegar. For binding, add 1 tbsp nutritional yeast to the batter.

The texture won’t be identical, but the vinegar brine and crispy coating stay intact. Serve with vegan ranch for full authenticity. 🌱
