Homemade cordon bleu: the cheese stays inside, the breadcrumb stays crispy
Shop-bought cordon bleu is convenient. Homemade cordon bleu is a different story: a tender escalope, real ham, oozing cheese and a golden crumb. The only challenge is stopping the cheese from escaping. Here's the step-by-step method, in a pan, in the oven or in air fryer mode.
- 4 servings, 30 min preparation
- Escalopes flattened to 5 mm, edges well sealed
- Double breading : the cheese no longer escapes
- Air fry 200 °C, 18 to 20 min, almost no oil
Appliance and settingPan on hob, or oven in air fry mode 200 °C
Ingredients
The children's favourite, but better
A cordon bleu is an escalope stuffed with ham and cheese, breaded then fried until golden. Homemade, it is thicker, juicier and far tastier than the frozen version. Two details make all the difference: a well-sealed escalope to keep the cheese inside, and controlled cooking, long enough to cook the chicken without burning the breadcrumbs.
The steps
- Flatten the meat. Place each escalope between two sheets of baking paper and beat it with the bottom of a saucepan until it is about 5 mm thick. Meat of even thickness cooks evenly.
- Fill. Season lightly with salt and pepper (the ham and cheese are already salty). On one half of the escalope, place a folded slice of ham then a slice of cheese, leaving 1 cm of free edge all around.
- Close. Fold the other half over and press the edges firmly with your fingers to seal them. If the escalope is too small, secure it with one or two cocktail sticks (to be removed before serving).
- Prepare the breading. Three shallow dishes: the flour, the eggs beaten with the milk, the breadcrumbs mixed with the Parmesan.
- Bread twice. Flour (tap off the excess), egg, breadcrumbs. Then dip back into the egg and a second time into the breadcrumbs, pressing well on the edges. It is this double coating that holds the cheese in.
- Chill. 20 minutes in the fridge, on a plate. The breading sets and will not come off during cooking.
- Cook in the pan… Heat the oil and butter in a large pan on the hob at level 6 (out of 9). When the butter foams, add the cordons bleus, then reduce to level 5. Allow 5 to 6 minutes per side, without moving them, until the breading is well browned.
- …or in the oven. Preheat in air fry mode to 200 °C (or in fan-assisted mode to 200 °C). Place the cordons bleus on the perforated tray or on a rack lined with baking paper, brush them with a tablespoon of oil. Put them in at level 2 for 18 to 20 minutes in air fry (22 to 25 minutes in fan-assisted mode), turning them halfway through.
- Check and serve. 74 °C at the centre, or clear juices. Let rest for 2 minutes before cutting, so the cheese doesn't run out all at once. Serve with a lemon wedge.
Appliance settings
| Step | Appliance and mode | Setting | Duration |
|---|---|---|---|
| Pan cooking | Induction hob | Level 6 to heat, then 5 | 5 to 6 min per side |
| Oven cooking (the lightest) | Oven, air fry mode | 200 °C, perforated tray level 2 | 18 to 20 min, turn halfway through |
| Oven cooking (without air fry) | Oven, fan-assisted | 200 °C, shelf level 2 | 22 to 25 min, turn halfway through |
| Homemade frozen cordons bleus | Oven, fan-assisted | 190 °C, rack level 2 | About 30 min |
| Doneness check | Probe or meat thermometer | 74 °C at the centre (chicken, turkey) | At the end of cooking |
A perforated tray lets air pass under the meat: the underside stays crispy without needing much oil. On a solid tray, be sure to turn them halfway through.
Variations
- With pork or veal : this is the original Swiss version. Very thinly flattened veal escalope, 3 to 4 minutes per side in a pan.
- Belgian style : Ardennes ham and an abbey cheese in slices. Reduce the salt.
- Extra crispy : replace the breadcrumbs with panko, or add crushed cornflakes.
- Vegetarian : two slices of celeriac cooked for 8 minutes in water, with the cheese in between, breaded the same way.
Storage
Once cooked, cordons bleus keep 2 days in the fridge. To bring back their crispiness, forget the microwave: 10 minutes in air fry mode or fan oven at 180 °C. Raw and breaded, they freeze 3 months and cook straight from frozen, without thawing.
Use cheese in slices, not grated: a slice melts into a single layer and stays in the middle, whereas grated cheese always finds a way out. And if your oven has a temperature probe, insert it at an angle into the thickest part of the meat, without touching the cheese. With homemade chips, you've got the whole family's favourite meal.
Which appliance?
For a crispy cordon bleu with almost no oil, the air fry setting on the oven is ideal: the very hot air browns the breadcrumb coating on all sides at once.

Frequently asked questions
How do you stop the cheese leaking out of a cordon bleu?
Three steps: leave a 1 cm border free around the ham and cheese, press the edges of the meat firmly together to seal them, then coat twice (flour, egg, breadcrumbs, then egg and breadcrumbs again). Twenty minutes in the fridge before cooking firms everything up.
How do you know if the cordon bleu is cooked through?
Chicken must reach 74 °C at the centre: the simplest way is with the oven's temperature probe or a meat thermometer. Without a thermometer, the juices running from the meat should be clear, with no pinkness.
Can you freeze homemade cordon bleu?
Yes, raw and breaded. Lay them flat on a tray in the freezer, then transfer them to a bag. Cook them without thawing, in the fan oven at 190 °C, for about 30 minutes.
