Easy Air Fryer Potato Croquettes (Leftover Mashed Potatoes)

Air Fryer Potato Croquettes turn a bowl of leftover mashed potatoes into crispy, golden bites with a creamy center in about 35 minutes. Each croquette gets a crunchy panko crust in the air fryer, so you skip the pot of hot oil and the mess that comes with deep frying but keep every bit of the crispy-outside, soft-inside texture that makes croquettes so good.

This is the recipe I reach for whenever I have mashed potatoes left over from dinner. Roll them, bread them, air fry them, and you have an appetizer or side dish that disappears faster than you can plate it. They’re just as at home next to a weeknight dinner as they are on a party spread with a bowl of dipping sauce.

What Is a Potato Croquette?

A croquette is a small breaded, fried roll made from a thick base and a savory filling, coated in breadcrumbs and cooked until golden. In potato croquettes, mashed potato is the base, and the mix-ins can be anything from cheese and herbs to ham, bacon, or vegetables. Croquettes started in France and now show up in kitchens all over the world, each version shaped by local flavors.

The appeal is the contrast: a crunchy shell around a soft, creamy interior. Cooking them in the air fryer gives you that shell with a fraction of the oil, which is why this version has become a staple in my kitchen.

Why You’ll Love This Recipe

• A reliable crowd-pleaser. Bite-sized and dippable, they work as an appetizer, a snack, or a side dish.
• Less oil, same crunch. The air fryer crisps the panko coating with just a light spray of oil instead of a pot of it.
• A smart way to use leftovers. Leftover mashed potatoes are the perfect starting point, so nothing goes to waste.
• Fast and low-mess. No deep fryer to fill, heat, and clean up afterward.
• Endlessly customizable. Swap the cheese, add bacon, fold in herbs, or make them spicy.

Ingredients You’ll Need

The full measurements are in the printable recipe card below, along with nutrition information.

• Mashed potatoes – Cooled leftover or freshly made mashed potatoes form the creamy base. Let them come to room temperature so they’re easy to shape.
• Eggs – One goes into the potato mixture to bind it; two more are beaten for the coating.
• Grated cheese – Sharp cheddar, mozzarella, or Parmesan all melt into the center beautifully.
• Chopped ham or cooked bacon (optional) – For a smoky, savory bite.
• Green onions or chives – A little fresh onion flavor and a pop of color.
• Kosher salt and black pepper – Season the potato mixture well so the croquettes taste good all the way through.
• All-purpose flour – The first layer of the coating; it helps the egg and breadcrumbs grip.
• Breadcrumbs – Panko is my pick for the lightest, crispiest crust, but regular breadcrumbs work too.
• Cooking spray – A light mist before air frying is what turns the coating golden.

How to Make Air Fryer Potato Croquettes

Step 1: Mix the potato base. In a large bowl, combine the mashed potatoes, 1 beaten egg, grated cheese, ham or bacon (if using), green onions or chives, salt, and pepper. Mix until evenly combined.

Step 2: Shape the croquettes. Scoop the mixture and roll it into small logs or balls, keeping them a uniform size so they cook evenly.

Step 3: Set up a breading station. Use three shallow dishes: one with flour, one with the 2 beaten eggs, and one with breadcrumbs.

Step 4: Coat each croquette. Roll in flour and shake off the excess, dip into the egg, then roll in breadcrumbs until fully coated.

Step 5: Preheat the air fryer to 400°F (200°C) for 5 minutes so the crust starts crisping the moment the croquettes go in.

Step 6: Air fry. Arrange the croquettes in a single layer in the basket with space between them so the air can circulate, and mist lightly with cooking spray. Air fry at 400°F for 10 to 12 minutes, flipping halfway through, until golden brown and crisp. Work in batches if your basket is small.

Step 7: Rest and serve. Move the croquettes to a wire rack for a couple of minutes to stay crisp, then serve warm with your favorite dip.

Pro Tips for the Crispiest Croquettes

• Keep them uniform. Same-size croquettes cook at the same rate.
• Chill before frying. Thirty minutes in the fridge helps shaped croquettes hold together and keeps the coating neat.
• Reach for panko. Its flaky texture crisps up lighter than standard breadcrumbs.
• Don’t crowd the basket. Leave space around each one so hot air can reach every side.
• Mist, don’t drench. A light spray of oil is all it takes for that golden color.
• Flip halfway. Turning them once gives you an even, all-over crisp.

Flavor Variations

Once you have the base down, the mix-ins are up to you:

• Cheesy jalapeño – Chopped jalapeño plus extra sharp cheddar for heat balanced by creamy potato.
• Sweet potato – Swap in mashed sweet potato with a pinch of cinnamon and nutmeg.
• Bacon and chive – Crispy bacon bits and chives for a loaded-potato feel.
• Mozzarella-stuffed – Tuck a small cube of mozzarella into the center for a gooey pull.
• Garlic Parmesan – Grated Parmesan and minced garlic folded into the mix.
• Vegan – Use a plant-based cheese and an egg substitute, and bread with panko.

If you love the croquette format, try the same technique with meat: my Air Fryer Chicken Croquettes and Air Fryer Turkey Croquettes are made the same crispy way and are perfect for using up cooked poultry.

What to Serve With Potato Croquettes

These croquettes round out a plate of air fryer favorites. They’re great alongside Air Fryer Garlic Parmesan Fries for a loaded snack board, next to Air Fryer Irish Potato Nachos for game day, or with Air Fryer Hasselback Sweet Potatoes when you want a heartier side. For a full air fryer dinner, serve them with Air Fryer Steak Fajitas or Frozen Beef and Broccoli in the Air Fryer.

Set out a few dips too. Marinara, garlic aioli, sour cream, or a creamy mustard sauce all pair well.

Storage and Reheating

• Refrigerator: Store cooked croquettes in an airtight container for up to 3 days.
• Freezer: Freeze shaped, breaded (uncooked) croquettes on a tray until solid, then transfer to a freezer bag. Air fry straight from frozen, adding a few extra minutes.
• Reheat: Warm cooked croquettes in the air fryer at 350°F (175°C) for 3 to 5 minutes to bring the crisp back, which works far better than the microwave.

Frequently Asked Questions

Can I use instant mashed potatoes?

Yes. Prepare them, let them cool to room temperature, then mix with the other ingredients. The texture will be a little different from homemade, but it works well as a shortcut.

How do I keep the croquettes from falling apart?

Make sure the potato mixture isn’t too wet, chill the shaped croquettes before breading, and coat them fully in breadcrumbs. Place them gently in the basket and flip carefully.

Can I make them gluten-free?

Yes. Use a gluten-free flour blend and gluten-free breadcrumbs for the coating.

Can I freeze them before cooking?

Yes. Freeze the shaped, breaded croquettes on a tray until solid, then bag them. Air fry from frozen and add a few extra minutes.

Why did my croquettes turn out dry?

Dry croquettes usually mean they were overcooked or the potato mixture needed more moisture. Follow the mixture ratios and check them a minute or two early, since air fryer models vary.

What sauces go best with them?

Aioli, marinara, ranch, tonkatsu sauce, or a simple sour cream and chive dip all work beautifully.
