WHAT ARE REUBEN BALLS?

Reuben Balls are a deconstructed, bite-sized version of the classic Reuben sandwich. Where the original features corned beef, sauerkraut, Swiss cheese, and Thousand Island dressing layered between slices of rye bread, Reuben Balls take all those same fillings, mix them together into a compact ball, bread them in seasoned breadcrumbs, and deep-fry them until golden and crispy.

The result is a finger food that captures every flavor note of the original sandwich — the savory beef, the tangy sauerkraut, the nutty melted Swiss — in a single crispy, poppable bite. They are served with a spicy Thousand Island dipping sauce on the side which replaces the dressing that would normally be inside the sandwich.

WHY YOU WILL LOVE THIS RECIPE

• All the Reuben flavors in one bite: Every single element of the classic Reuben sandwich — corned beef, sauerkraut, Swiss cheese, Dijon, Thousand Island — is packed into one crispy little ball. It is the whole sandwich experience without the bread.

• Incredible texture contrast: The breadcrumb coating fries up shatteringly crispy while the inside stays warm, gooey, and melty. That hot-and-crispy versus warm-and-cheesy contrast is what makes these so addictive.

• Perfect party and game day food: Easy to eat standing up, no utensils needed, poppable in one bite. These are exactly what party food should be — impressive to look at, easy to eat, and impossible to stop eating.

• Make-ahead friendly: Mix the filling, shape the balls, bread them, and refrigerate for up to 24 hours before your event. Fry them fresh right before serving for maximum crunch — no last-minute prep stress.

• The dipping sauce is addictive: The spicy Thousand Island sauce takes about 2 minutes to make and is so good you will want to put it on everything. Creamy, tangy, smoky, with a kick of heat — it elevates these balls from great to unforgettable.

• Three cooking methods: Deep-fry for maximum crunch, bake for a lighter option, or air fry for the best of both worlds — crispy outside with minimal oil. All three methods work beautifully.

• Freezer-friendly: Make a big batch, freeze the uncooked breaded balls, and fry straight from frozen whenever you need a quick impressive appetizer. They go from freezer to table in under 10 minutes.

INGREDIENTS

Here is everything you need for the Reuben Balls and the spicy dipping sauce, with notes on each ingredient:

For the Reuben Balls:

• 2 cups cooked corned beef, finely chopped — Use leftover corned beef, deli corned beef, or canned corned beef. Chop it as finely as possible so the filling holds together cleanly. The smaller the pieces the easier the balls are to shape and the less likely they are to fall apart during frying.
• 1 cup sauerkraut, drained and chopped — This is the most important prep step in the entire recipe. Squeeze every drop of liquid out of the sauerkraut using your hands or a clean kitchen towel. Excess moisture is the number one reason Reuben Balls fall apart — properly drained sauerkraut prevents this completely.
• 1 cup shredded Swiss cheese — Swiss is traditional and melts beautifully into the filling. Shred it yourself from a block rather than using pre-shredded — block cheese melts more smoothly and has better flavor. Gruyère is an excellent upgrade if you want a nuttier, more intense cheese flavor.
• 1 cup mashed potatoes (optional, for binding) — Adds body and helps the filling hold together without making it dense. Use plain mashed potatoes with no extra seasoning. If you skip this, use 2 tablespoons of cream cheese as a binding alternative — it works just as well and adds a pleasant richness.
• 1 tablespoon Dijon mustard — Adds the sharp, tangy mustard note that is essential to the Reuben flavor profile. Do not substitute with yellow mustard — Dijon has the right sharpness and complexity.
• 1 teaspoon health benefits of garlic powder — Adds a subtle savory depth to the filling without overpowering the other flavors.
• 2 eggs, beaten — Used for the breading station. The egg wash helps the breadcrumbs adhere to the balls and creates a seal that keeps the filling inside during frying.
• 1½ cups breadcrumbs — Panko breadcrumbs give the crispiest, crunchiest coating and are strongly recommended over regular breadcrumbs. Season with a pinch of salt, pepper, and garlic powder for extra flavor. For a nod to the original rye bread, use rye breadcrumbs if you can find them.
• Oil for frying — Use a neutral oil with a high smoke point — vegetable oil, canola oil, or peanut oil all work well. You need enough oil to submerge the balls at least halfway, ideally fully.

For the Spicy Thousand Island Dipping Sauce:

• ½ cup mayonnaise — The creamy base. Full-fat mayo gives the best flavor and consistency.
• 3 tablespoons ketchup — Adds sweetness, color, and that classic Thousand Island tang.
• 1 tablespoon sweet pickle relish — The defining ingredient of Thousand Island dressing. Do not skip it.
• 1 teaspoon hot sauce, adjusted to taste — Frank's RedHot or Tabasco both work perfectly. Start with 1 teaspoon and add more to taste. For a milder sauce use just ½ teaspoon.
• ½ teaspoon smoked paprika — Adds a subtle smokiness that takes this sauce from basic Thousand Island to something genuinely special.
• Salt and pepper to taste — Season after mixing and taste before serving.

DIRECTIONS

• Step No.1: Make the dipping sauce first
  In a small bowl whisk together the mayonnaise, ketchup, sweet pickle relish, hot sauce, smoked paprika, salt, and pepper until fully combined and smooth. Taste and adjust the heat level by adding more hot sauce if desired. Cover and refrigerate while you prepare the Reuben Balls — chilling the sauce for at least 20 minutes allows the flavors to meld together and improves the taste significantly. The sauce can be made up to 3 days ahead and stored in the fridge.

• Step No.2: Prepare the filling
  In a large mixing bowl combine the finely chopped corned beef, thoroughly drained and chopped sauerkraut, shredded Swiss cheese, mashed potatoes if using, Dijon mustard, and garlic powder. Mix everything together until fully and evenly combined. The mixture should hold together when you squeeze a small amount in your palm — if it is too wet or crumbly add a tablespoon of cream cheese or an extra tablespoon of mashed potato to help it bind.

• Step No.3: Shape the balls
  Using a tablespoon or small cookie scoop, portion the filling and roll firmly between your palms to form compact 1½-inch balls. Place each ball on a parchment-lined baking sheet as you go. If the mixture is sticking to your hands, lightly dampen them with cold water. Once all the balls are shaped, place the baking sheet in the refrigerator and chill for at least 20 to 30 minutes. This step is essential — chilling firms the balls so they hold their shape during breading and frying without falling apart.

• Step No.4: Set up the breading station
  Place the beaten eggs in one shallow bowl and the breadcrumbs in another. For extra crunch use panko breadcrumbs and season them with a pinch of salt, pepper, and garlic powder. Working one at a time, roll each chilled ball in the beaten egg until fully coated, then immediately roll in the breadcrumbs pressing gently to ensure the crumbs adhere evenly all over. For an extra thick, extra crispy coating double-bread them — egg, breadcrumbs, egg again, breadcrumbs again. Place breaded balls back on the parchment-lined tray.

• Step No.5: Fry until golden
  Pour oil into a deep skillet, Dutch oven, or deep fryer to a depth of at least 2 inches. Heat to 350°F (175°C) — use a kitchen thermometer for accuracy. The right oil temperature is critical: too low and the balls absorb oil and become greasy, too high and the outside burns before the inside heats through. Fry the balls in small batches of 4 to 6 at a time — do not crowd the pan as this drops the oil temperature. Fry for 3 to 4 minutes, turning occasionally, until deep golden brown all over. Remove with a slotted spoon and drain on a paper towel-lined plate. Let the oil return to 350°F between batches.

• Step No.6: Serve immediately
  Arrange the hot Reuben Balls on a serving platter alongside the chilled spicy Thousand Island dipping sauce. Garnish with a sprinkle of fresh chopped parsley or a light dusting of smoked paprika for presentation. Serve immediately while the coating is still crispy and the filling is hot and gooey — these are at their absolute best in the first 10 minutes after frying.

TIPS FOR SUCCESS

• Drain the sauerkraut completely: This cannot be overstated. Wet sauerkraut is the single most common reason Reuben Balls fall apart in the fryer. Drain it in a strainer, then squeeze it in your hands, then squeeze it again in a clean kitchen towel. It should be almost completely dry before mixing.

• Always chill before frying: Do not skip the 20 to 30 minute refrigeration step. Chilled balls are firm, hold their shape during breading, and do not expand and crack open during frying. Warm balls will fall apart in the oil.

• Use panko breadcrumbs: Panko gives a significantly crispier, lighter, crunchier coating than regular fine breadcrumbs. It is worth seeking out — most supermarkets stock it in the Asian foods aisle or baking aisle.

• Monitor oil temperature: Use a kitchen thermometer. Dropping below 340°F produces greasy, soggy balls. Going above 375°F burns the outside before the inside is hot. Keep a close eye on it and adjust the heat between batches.

• Fry in small batches: Adding too many balls at once drops the oil temperature sharply. Fry 4 to 6 at a time maximum and always let the oil recover to 350°F before adding the next batch.

• Make the sauce ahead: The spicy Thousand Island sauce tastes better after sitting in the fridge for at least 20 minutes. Make it first or even the day before so the flavors have time to develop fully.

• Serve immediately: Fried foods are always best the moment they come out of the oil. If you are serving these at a party, fry them in batches as guests arrive rather than all at once so they are always fresh and hot.

VARIATIONS

• Baked Reuben Balls: Place breaded balls on a greased baking sheet, spray generously with cooking spray or brush with oil, and bake at 400°F (200°C) for 18 to 22 minutes, turning halfway through, until deep golden brown. Not quite as crispy as fried but significantly lighter and much less messy.

• air fryer cooking Reuben Balls: Preheat air fryer to 375°F. Spray breaded balls generously with cooking spray and air fry in a single layer for 10 to 12 minutes, shaking the basket halfway through, until golden and crispy. This method gives excellent results with minimal oil — almost as crispy as deep-fried.

• Pastrami Reuben Balls: Swap the corned beef for pastrami for a smokier, more peppery flavor profile. Pastrami is more intensely seasoned than corned beef which gives the balls a bolder taste that many people prefer.

• Spicy Reuben Balls: Add 2 tablespoons of finely chopped pickled jalapeños and a teaspoon of hot sauce directly into the filling mixture for heat in every single bite, not just the dipping sauce.

• Caraway rye coating: Mix 1 teaspoon of crushed caraway seeds into the breadcrumbs before breading. This adds the distinctive rye bread flavor of the original sandwich to the crispy exterior — a small touch that makes a big difference.

• Different cheeses: Swap Swiss for Gruyère for a more complex nutty flavor, provolone for a milder melt, or pepper jack for a spicier kick. Any good melting cheese works well in this recipe.

SERVING AND STORAGE

Serving

Serve Reuben Balls immediately after frying while the coating is at peak crispiness and the filling is hot and gooey. Arrange on a platter with the spicy Thousand Island dipping sauce in a small bowl alongside. For parties, provide toothpicks for easy grabbing. Garnish with a light sprinkle of smoked paprika or fresh chopped chives for a professional presentation. These also pair beautifully alongside other appetizers — try them next to our Creamy Bruschetta Dip or our Marinated Cheese Appetizer with Salami and Pickles for a complete appetizer spread.

Storage

Store leftover cooked Reuben Balls in an airtight container in the refrigerator for up to 3 days. Reheat in a 375°F oven for 8 to 10 minutes or in the air fryer at 350°F for 4 to 5 minutes until hot and crispy again. Do not microwave — it makes the coating soft and soggy. The dipping sauce keeps in the fridge for up to 5 days in a sealed jar.

Freezer instructions: To freeze uncooked breaded Reuben Balls, place them on a parchment-lined tray and freeze until completely solid, about 2 hours. Transfer to a freezer-safe zip-lock bag and freeze for up to 3 months. Fry directly from frozen at 350°F for 5 to 6 minutes — no thawing needed. You can also air fry from frozen at 375°F for 14 to 16 minutes. This makes them an incredible make-ahead party appetizer you can pull out of the freezer at a moment's notice.
