Potato croquettes belong to the kind of side dish that turns an ordinary weeknight dinner into something that feels like restaurant food. Outside, a golden-brown, crunchy breadcrumb crust; inside, a fluffy potato mash with a hint of nutmeg. Traditionally, they’re fried in a pot of boiling oil, and that’s exactly what has kept many people from making them at home.

In the air fryer, all you need is two tablespoons of oil for brushing, and the croquettes still turn out crispy all the way around. They bake for 14 minutes at 200°C and come out with exactly the crust you’re hoping for. Here’s the method, the three classic pitfalls, and my experience from the kitchen.

Why I Love Potato Croquettes in the Air Fryer
The biggest win is that deep-frying disappears completely. No pot with a liter of oil, no splatters on the stove, and no question about what to do with the oil afterward. Two tablespoons brushed onto the croquettes do the same job as a deep fryer: the oil carries heat into the breadcrumbs, so they turn golden and crunchy instead of dry and pale.
Control is better too. In a pot, the oil temperature drops every time you add a cold croquette, and the last batches rarely turn out as nice as the first. The air fryer holds a constant 200°C, and with one flip after 8 minutes, all 12 croquettes come out the same. The mash still needs to chill for 30 minutes in the fridge either way, so most of the work can be done well ahead of time.
Why Floury Potatoes Make All the Difference
The choice of potato determines whether the croquettes hold their shape. Floury varieties like Bintje and King Edward have low water content and a dry, crumbly texture that binds with the egg yolks into a firm mass. Waxy potatoes contain too much water, and the mash turns gluey instead of fluffy. After boiling, the potatoes need to steam dry in the hot pot for two to three minutes. Most people skip this step, and that’s often where the croquettes start to crack.
My Kitchen Test of Potato Croquettes
I’ve run the batch through several times in my Cosori Dual Blaze, and 14 minutes at 200°C is the point where the crust turns golden all the way around without the mash inside drying out. I first tried taking them out earlier, and the underside was still pale. The flip after 8 minutes is non-negotiable: without it, the croquettes get a flat, pale underside where they sat against the basket.
The chilling time surprised me the most. When I shaped the croquettes from warm mash, three out of twelve cracked in the basket. With the full 30 minutes in the fridge, all twelve held their shape. The final two minutes of resting in the basket after baking are also worth it, since that’s when the crust sets, letting the croquettes be lifted out without breaking.
Brush the croquettes on all sides, including the ends. A dry spot in the breadcrumbs never turns golden — it just turns floury.
Tips and tricks from the author: Morten Jensen
The Typical Mistakes and How to Avoid Them
The most common mistake is mash that’s too wet. If the water isn’t steamed off, or milk and cream get added, you end up with a mixture that can’t hold its shape and cracks in the heat. Use only butter and egg yolks, and let the potatoes dry in the pot before mashing them. The next mistake is an overcrowded basket. If the croquettes lie against each other, air can’t circulate, and the sides that touch turn soft and pale instead of crispy. Place them in a single layer with air between them, and do two batches instead. The third mistake is patchy coating. Even just a couple of bare spots where the mash shows through will push out during baking. Turn the croquettes thoroughly in the breadcrumbs, and check the ends, which are easy to forget.
How to Serve Potato Croquettes
The croquettes step in exactly where you’d otherwise serve boiled potatoes, and they especially shine with meals that involve gravy or sauce.
- With roast meat and a rich gravy, where the crust can soak some up
- As a side for Danish meatballs with a tangy salad
- With steak and béarnaise sauce instead of french fries
- As part of a tapas spread with aioli and pickled vegetables
- With fried fish, remoulade, and lemon
Storage and Reheating
Fully baked croquettes keep covered in the fridge for up to two days. Reheat them in the air fryer at 180°C for four to six minutes, until crispy and heated through again. The lower temperature than the original baking keeps them from drying out. The microwave ruins the crust in half a minute, so skip that. If you want to freeze them, do it while the croquettes are still coated and raw: they keep for up to three months and bake straight from frozen at 200°C for 16-18 minutes.
Potato croquettes elevate the rest of the plate without requiring anything more than potatoes you already have on hand. Feel free to make a double batch and put half of the coated croquettes in the freezer, so your next Sunday roast is already half planned.
FAQ
Yes, if the mash was made without milk or cream. Mash mixed with milk contains too much liquid to hold its shape and will crack in the basket. Stir egg yolks, salt, and nutmeg into the cold mash, and check that the mixture is firm enough to hold its shape.
This is almost always because the mash is too wet or not cold enough. Let the potatoes steam dry after boiling, and refrigerate the mash for at least 30 minutes. Air pockets cause the same problem, so press the croquettes together firmly when shaping them.
Yes. The croquettes need to go in at 200°C so the breadcrumbs start browning right away. If you put them in a cold basket, the coating absorbs the oil before the heat takes hold, and the crust turns greasy instead of crispy.

Shopping list
Ingredients
- 800 g floury potatoes (E.g. Bintje or King Edward)
- 30 g butter
- 2 pcs egg yolks
- 1 tsp salt
- 0.5 tsp nutmeg (Freshly grated)
- 0.25 tsp black pepper (Freshly ground)
Coating
- 60 g plain flour
- 2 pcs eggs (Beaten)
- 120 g breadcrumbs
- 2 tbsp oil (For brushing)
How to make it
Preparation
- Peel 800 g floury potatoes and cut them into rough, even-sized pieces. Boil them until tender in lightly salted water for 18-20 minutes, drain, and let them steam completely dry in the hot pot for 2-3 minutes.
- Mash the potatoes until completely smooth while still hot, and stir in 30 g butter until melted. Avoid whisking the mash, as this will make it gluey.
- Stir 2 pcs egg yolks into the warm mash along with 1 tsp salt, 0.5 tsp nutmeg and 0.25 tsp black pepper. The mash needs to be thick and firm, not loose.
- Cover the mash and refrigerate for at least 30 minutes, until completely cold and firm enough to shape.
Coating
- Shape the mash into 12 oblong croquettes about 7 cm long with slightly damp hands. Press them together firmly so there are no air pockets that could make them crack.
- Coat the croquettes first in 60 g plain flour, then in 2 pcs eggs and finally thoroughly in 120 g breadcrumbs, so the whole surface is covered.
- Brush the croquettes lightly with 2 tbsp oil on all sides. The oil is what gives the golden, crispy crust in the air fryer.
Cooking in the air fryer
- Preheat the air fryer to 200 °C fan.
- Place the croquettes in the basket in a single layer so they don’t touch, and bake for 14 minutes at 200 °C. Turn them carefully after 8 minutes so they turn evenly golden all the way round.
- Let the croquettes rest for 2 minutes in the basket to let the crust set, and serve them hot.
Our notes for the recipe
Use floury potatoes and let them steam completely dry after boiling. A damp mash will make the croquettes crack and fall apart in the basket. The mash needs to be completely cold before you shape the croquettes. Variation:
Stir 40 g finely grated parmesan or a tablespoon of chopped parsley into the mash for extra flavour. Panko instead of breadcrumbs gives a coarser and even crispier crust. Serving:
Serve the croquettes with roast meat, meatballs or a good gravy instead of boiled potatoes. Portion size:
If your air fryer is smaller, you can cook the croquettes in two batches. They need to lie in a single layer to get crispy all the way round.
