Coat the Croquettes: One by one, coat each croquette in the flour, then dip it in the egg, and finally roll it in the breadcrumbs, ensuring an even coat for maximum crispiness.
-
Prepare for Air Frying: Place the coated croquettes in the air fryer basket in a single layer without overcrowding. Lightly spray them with olive oil to encourage a golden finish.
-
Air Fry: Set the air fryer to 400°F and cook for 8-10 minutes, flipping them halfway through until they are golden brown and crispy on the outside.
-
Serve: Once cooked, serve the croquettes hot with Thousand Island dressing for dipping—this adds that classic Reuben flavor that everyone loves!

Storage Tips for Reuben Croquettes
Fridge: Store leftovers in an airtight container for up to 3 days to maintain freshness and flavor.
Freezer: For longer storage, freeze uncooked Reuben croquettes on a baking sheet until firm, then transfer to a freezer bag. They can be air-fried directly from frozen, adding 2-3 minutes to the cooking time.
Reheating: If you’ve cooked croquettes, reheat them in the air fryer at 350°F for about 5 minutes until warmed through and crispy again.
Keep Coated: Properly coat your croquettes with flour, egg, and breadcrumbs before freezing to ensure they remain intact and fry beautifully.
Expert Tips for Reuben Croquettes
- Use Leftover Potatoes: For an even creamier filling, utilize leftover cold mashed potatoes instead of instant; they add great texture and flavor.
- Chill Before Shaping: If your mixture feels loose, chill it in the refrigerator for 20-30 minutes to make shaping the croquettes easier.
- Don’t Overcrowd: For perfectly cooked Reuben croquettes, avoid placing too many in the air fryer at once; this ensures each croquette gets crispy all around.
- Experiment with Cheese: For a twist, try adding small pieces of cheese inside each croquette for an oozy, delightful center as they cook.
- Adjust Cooking Time: Keep an eye on the cooking time; depending on your air fryer model, timing might differ. Start with 8 minutes, then check for the perfect golden brown exterior.
Reuben Croquettes Recipe FAQs
What type of potatoes should I use for the filling?
For the filling, I recommend using roasted garlic instant mashed potatoes for their creaminess. If you have leftover cold mashed potatoes, those work wonderfully too! Just add a touch of garlic powder for extra flavor.
How do I store leftover Reuben croquettes?
Store any leftover croquettes in an airtight container in the fridge for up to 3 days. Make sure they are completely cooled before sealing the container to maintain their texture and flavor.
Can I freeze Reuben croquettes?
Absolutely! To freeze uncooked croquettes, place them on a baking sheet in a single layer until firm, about an hour.
