Pork rump roast in the air fryer is my shortcut to a proper Sunday roast, without having to fire up the big oven. Pork rump roast is a lean, triangular roast from the leg of pork with a fat cap on top, and the hot air handles that combination beautifully: the fat cap turns golden while the meat underneath stays juicy.

I season it very simply with coarse salt, freshly ground black pepper and fresh thyme. What matters is not the seasoning but the internal temperature. The meat is so lean that it turns dry if it cooks for too long, so here is my method, with a meat thermometer, an unhurried rest and thin slices. A 1 kg roast serves 4 people.

Why I love pork rump roast in the air fryer
Pork rump roast is a lovely, uncomplicated roast, but it has a reputation for turning dry. That is almost always because it has been cooked for too long, or at too high a heat all the way through. In the air fryer the roast first gets 10 minutes at 200 °C, so the scored fat cap takes on colour, and then it finishes cooking at 160 °C. The lower temperature gives the lean meat time to cook through gently, without the outside drying out.
I pick the leaves from half of the thyme and rub them into the scores along with the salt and pepper. The other half goes in as whole sprigs in the bottom of the basket, with the roast on top. That way the aroma fills the kitchen while the roast more or less takes care of itself, and I only need to turn it twice along the way.
The difference between an air fryer and an oven
A regular oven has to heat up a large oven cavity just to cook a single 1 kg roast. In the air fryer, the hot air circulates close around the meat, so the fat cap takes on colour within the first 10 minutes. It is also easy to pull out the basket, turn the roast with tongs and push the meat thermometer into the thickest part.
My kitchen test of pork rump roast
I tested the recipe with a 1 kg pork rump roast in my Cosori Dual Blaze, where heating elements at both the top and the bottom give even cooking above and below. I still turn the roast twice, exactly as in the recipe: first it gets 10 minutes at 200 °C with the fat cap facing up, then 20 minutes at 160 °C with the fat cap facing down, and finally 15-20 minutes at 160 °C with the fat cap facing up again.
The meat thermometer read 70 °C in the thickest part when the roast had had its 50 minutes in total, and after 15 minutes of resting, loosely covered with aluminum foil, the slices were juicy all the way through. Allow about 75 minutes from start to serving, including preparation and resting time. In a Philips XXL there is plenty of room around the roast, but a 1 kg pork rump roast fits in most air fryers from around 4 litres.
I always trust the meat thermometer more than the clock. The roast comes out when the thickest part reads 70 °C, and then it gets its 15 minutes of rest before the knife comes out.
Tips and tricks from the author: Morten Jensen
The typical mistakes and how to avoid them
The most common mistake is to cook by the clock alone. Pork rump roast is lean meat, and a few minutes too many will dry it out, so measure the internal temperature in the thickest part and take the roast out at 70 °C. If it is a few degrees short, give it 3-5 more minutes at a time at 160 °C, and then measure again.
The second mistake is scoring too deeply. The cuts should be about 1 cm apart and go through the fat only, not down into the meat, otherwise the meat juices run out during cooking. The third mistake is carving the roast straight away. Give it 15 minutes of rest, loosely covered with aluminum foil, and then cut it into thin slices across the grain. That way even the lean meat turns out tender.
How to serve pork rump roast
Pork rump roast is a classic Danish roast, and the side dishes can happily be just as classic. Here are my favourites:
- Fried potatoes or creamy mashed potatoes
- Brown gravy or a cream sauce
- Green beans or other seasonal vegetables
- A crisp salad as a fresh counterpoint to the roast
- Cold leftovers in thin slices on rye bread the next day
Storage and reheating
Leftover pork rump roast can be stored covered in the fridge for up to 3-4 days. Reheat the slices in the air fryer at 170 °C for 5-7 minutes, until the meat is heated through. The roast can also be frozen for up to 3 months, and then it needs to thaw in the fridge overnight before reheating. It helps to slice the leftovers first, so they are easy to take out in portions.
With a meat thermometer, an unhurried rest and a sharp knife, pork rump roast in the air fryer is a roast that turns out right every time. You will find all the quantities and steps in the recipe at the bottom of the page.
FAQ
A 1 kg pork rump roast needs about 50 minutes in the air fryer: 10 minutes at 200 °C and the rest of the time at 160 °C. Then it rests for 15 minutes. Always let the meat thermometer decide when the roast is done.
The pork rump roast is done when the meat thermometer reads 70 °C in the thickest part of the roast. Then let it rest for 15 minutes, loosely covered with aluminum foil, before you carve it.

Ingredients
- 1 kg pork rump roast (Roast from the leg of pork with a fat cap)
- 1 tbsp olive oil
- 6 sprigs fresh thyme
- 2 tsp coarse salt
- 1 tsp black pepper (Freshly ground)
How to make it
Preparation
- Pat 1 kg pork rump roast completely dry on all sides with paper towels.
- Score the fat cap in a diamond pattern with a sharp knife, spacing the cuts about 1 cm apart. Cut only through the fat and not into the meat.
- Rub the roast all over with 1 tbsp olive oil.
- Divide 6 sprigs fresh thyme into two equal portions. Pick the leaves from one half, and keep the other half as whole sprigs.
- Season the roast all the way round with 2 tsp coarse salt, 1 tsp black pepper and the picked thyme leaves, and rub the seasoning well into the scores in the fat.
Cooking in the air fryer
- Preheat the air fryer to 200 °C fan.
- Place the whole thyme sprigs in the bottom of the basket, and put the roast on top with the fat cap facing up. Cook at 200 °C for 10 minutes, until the fat cap has taken on colour.
- Turn the temperature down to 160 °C. Turn the roast over with tongs so the fat cap faces down, and cook at 160 °C for 20 minutes.
- Turn the roast over again so the fat cap faces up, and continue cooking at 160 °C for 15-20 minutes.
- Measure the internal temperature in the thickest part of the roast with a meat thermometer. The roast is done when the thermometer reads 70 °C. If it is a few degrees short, continue cooking at 160 °C for 3-5 minutes at a time, and measure again.
Serving
- Place the roast on a cutting board, cover it loosely with aluminum foil, and let it rest for 15 minutes.
- Cut the roast into thin slices across the grain with a sharp knife, and serve straight away.
Our notes for the recipe
Pork rump roast is a lean, triangular roast from the leg of pork, and the meat quickly turns dry if it is cooked for too long. So trust the meat thermometer rather than the clock, and take the roast out as soon as the thickest part reads 70 °C. Let it rest for the full 15 minutes so the juices stay in the meat, and cut it into thin slices across the grain – that makes the lean meat tender. It also helps to take the roast out of the fridge 20-30 minutes before cooking, so it cooks more evenly. Variation:
Swap the thyme for rosemary or sage, or rub the roast with 1 tsp smoked paprika along with the salt and pepper. You can also brush the fat cap with a little coarse mustard when you turn the roast for the last time. Serving:
Serve the slices with fried potatoes or mashed potatoes, a cream sauce or brown gravy and seasonal vegetables, for example green beans or a crisp salad. Cold leftovers taste great in thin slices on rye bread. Portion size:
A 1 kg pork rump roast fits in most air fryers from around 4 litres. If your roast is larger or smaller, the cooking time changes, so always let the meat thermometer decide when it is done.
