Chateaubriand is the cut of meat you save for the good evenings. It comes from the thick end of the beef fillet, and it is so tender that it barely needs a knife. That is also exactly why it is the kind of meat you are most afraid of getting wrong — a couple of minutes too long, and the expensive cut is grey all the way through.

The air fryer actually makes the job easier than the pan. The hot air circulates evenly around the meat, you do not have to stand there turning it, and you get a beautifully browned surface without filling the kitchen with smoke. With 200 °C and a meat thermometer in hand, the whole dish is ready in 47 minutes — resting time included.

Why I love chateaubriand in the air fryer
A chateaubriand is expensive, and it deserves to be treated accordingly. In the air fryer I have control over the temperature the whole way through: no cold zone in the middle of the basket, and no pan that suddenly gets too hot while my back is turned. The meat gets even heat from all sides, and that means the pink centre stays the same from end to end instead of having a wide grey band around it.
Then there is the practical side. The air fryer is hot in a couple of minutes, it does not tie up the oven, and when you are cooking a big dinner, it is worth its weight in gold that the main course looks after itself for 22 minutes while you deal with the sauce and the side dishes.
The difference between the air fryer and the oven
The difference lies in the air circulation. A regular oven heats up the space and lets the heat find the meat at its own pace, while the air fryer blows the hot air straight at the surface. That gives faster browning at the same temperature, which is why 200 °C in an air fryer is not quite the same as 200 °C in an oven. Expect to be finished sooner, and let the thermometer — not the clock — decide when the meat comes out.
My kitchen test: chateaubriand
I have roasted chateaubriand in my Cosori Dual Blaze at 200 °C, and 22 minutes is the point where it comes out exactly right for me. The core temperature was 56 °C when I took the meat out, and to my taste that is where a beef fillet is at its very best: pink all the way through, but warm enough that the juices have spread.
The most important thing I have learnt along the way is that the resting time is not optional. I let the meat rest for 10 minutes under a loose piece of foil before I carve it. If you cut it straight away, the juices run out onto the board instead of staying in the meat. With 15 minutes of preparation, 22 minutes of roasting and 10 minutes of resting, the whole dish comes to 47 minutes.
A meat thermometer is not an accessory for a chateaubriand — it is the only tool that tells you the truth about what is going on inside the meat.
Tips and tricks from the author: Morten Jensen
The typical mistakes and how to avoid them
The first mistake is putting the meat straight from the fridge into the basket. A cold piece of meat heats up unevenly, and you end up with an overcooked outer edge and a centre that is too raw, so take it out 30-45 minutes before it goes in. The second mistake is trusting the clock instead of the thermometer; the thickness of a chateaubriand varies from butcher to butcher, and two pieces of the same weight can easily need different times. Aim for 56 °C in the middle rather than counting minutes. The third mistake is overfilling the basket. If the meat is squeezed up against the walls or sitting on top of the side dishes, the air cannot get round it, and the surface browns in patches — give the meat room of its own, and add the side dishes afterwards.
How to serve chateaubriand
Chateaubriand is classic food, and it suits classic side dishes. These are the combinations I keep coming back to:
- Béarnaise sauce and crispy fries — the original and still the best
- Dauphinoise potatoes or small potatoes fried in butter with parsley
- Roasted portobello or field mushrooms tossed in butter and thyme
- Green beans with flaky sea salt and a touch of grated lemon zest
- A rich red wine sauce made with beef stock
Storage and reheating
Leftovers from a chateaubriand are pure luxury in a packed lunch. Store the meat in an airtight container in the fridge and eat it within two days. Reheating is exactly where pink meat usually gets ruined, so be gentle: give the slices 2-3 minutes at 150 °C and no more. Personally I prefer the leftovers cold in a sandwich with remoulade and crispy fried onions, because the meat then keeps exactly the colour and tenderness it had the night before.
A chateaubriand in the air fryer is neither difficult nor unpredictable once you have a thermometer and the patience for the resting time. Buy a good piece of meat, stick to the 200 °C, and let the 56 °C decide when dinner is ready.
Frequently asked questions
At 200 °C a chateaubriand takes about 22 minutes in the air fryer, and then it needs to rest for 10 minutes. The thickness varies from piece to piece, so use a meat thermometer and take the meat out at 56 °C in the middle.
I take the meat out at 56 °C, which gives a pink medium rare. The core temperature rises a couple of degrees while it rests, so measure in the thickest part and let the meat rest for 10 minutes before you carve it.
No, it is not necessary. The hot air at 200 °C browns the surface all the way round on its own, and you save both a pan and the risk of overcooking the edges.

Ingredients
Chateaubriand
- 800 g chateaubriand (Centre cut of beef fillet, at room temperature for 30 minutes)
- 1 tbsp olive oil (For brushing)
- 1 tsp flaky sea salt
- 1 tsp black pepper (Freshly ground)
Herb butter
- 100 g butter (Softened)
- 2 clove garlic (Finely grated)
- 2 tbsp parsley (Freshly chopped)
- 1 tbsp tarragon (Freshly chopped)
- 1 tsp lemon juice
- 0.5 tsp salt
How to make it
Preparation
- Take 800 g chateaubriand out of the fridge 30 minutes before cooking, and pat the meat completely dry. A piece of meat that is at room temperature and dry gets a far better crust in the air fryer.
- Brush the meat all the way round with 1 tbsp olive oil, and season it generously with 1 tsp flaky sea salt and 1 tsp black pepper.
- In a bowl, beat 100 g butter until soft, then stir in 2 clove garlic, 2 tbsp parsley, 1 tbsp tarragon, 1 tsp lemon juice and 0.5 tsp salt. Chill the herb butter while the meat roasts.
Cooking in the air fryer
- Preheat the air fryer to 200 °C fan for 3-4 minutes.
- Place the chateaubriand in the basket with air all the way round the piece, and roast it at 200 °C for 8 minutes.
- Turn the meat, and continue roasting at 200 °C for 8-14 minutes depending on thickness. Insert the meat thermometer into the thickest part: 52 °C gives rare, 56 °C medium rare and 60 °C medium.
- Take the meat out, place it on a cutting board, and cover it loosely with foil. Let it rest for 10 minutes, so the juices spread through the whole piece.
Serving
- Cut the chateaubriand into slices about 1.5 cm thick, against the grain.
- Serve the slices with a knob of cold herb butter on top, so it melts down over the hot meat.
Our notes for the recipe
Use a meat thermometer rather than the clock — a chateaubriand varies in thickness, and the last few degrees go quickly. Take the meat out 2-3 °C below the core temperature you want, as the temperature keeps rising while it rests. Variation:
Replace the herb butter with a classic béarnaise, or stir a couple of tablespoons of blue cheese into the butter for a stronger version. Serving:
Serve with fries from the air fryer, roasted root vegetables or a crisp salad with mustard dressing. About the cut:
Chateaubriand is a piece of meat cut from the beef fillet — more precisely the thick centre section. Ask your butcher for an even piece of about 800 g, so it roasts evenly all the way through. Portion size:
If your air fryer is on the smaller side, you can divide the meat into two pieces and roast them in two batches. In that case, reduce the roasting time by 4-5 minutes per piece.
