This Air Fryer Topside Beef Roasting Joint recipe is a great way to quickly roast this popular cut of beef. I've included instructions to make a simple but delicious gravy from the beef drippings and as always, comprehensive step-by-step photos for how to prepare the beef and air fry it to perfection.
Make sure that the joint has plenty of clearance in the air fryer with the drawer shut/lid on/door closed. Joints of meat have a tendency of expanding as they start to cook so bear this in mind.If you think there might be an issue, remove any string from the joint and unroll it as much as possible. You can also consider removing the crisper rack.
Air Fry The Beef
If your air fryer requires pre-heating, start this setting now.
Thoroughly dry a 1 kg Beef Topside Joint and remove any string/netting - it isn't needed.
Drizzle with roughly 1 tbsp Vegetable Oil and rub all over the joint including the underneath and ends.
Season well with roughly 2 tsp Sea Salt Flakes. Again, don't miss all the sides and underneath.
Place the beef into the air fryer basket. If it is a preheated basket, use 2 forks to lower the meat in so you don't touch the hot metal with your hands.
Air fry for 15 minutes at 180℃/350℉.
Turn the beef in the basket.
Air fry for a further 15 minutes at 170℃/350℉. This will cook to a medium rare. Add 5 minutes for medium and a further 5 for medium well. If you prefer beef any more cooked than that, this isn't the right cut and cooking method of beef - it will just be tough. Remember that the beef will continue cooking slightly as it rests.
Allow the beef to rest for at least 15 minutes. You can either leave it in the air fryer turned off or wrap it in foil and cover with a towel. Use this time to make the gravy.
Pour any juices and fat from the basket into a small saucepan. Don't forget to add any juices from the resting period to the reserved juices/fat or gravy if it's already made.
Carve into thick or thin slices as preferred and serve.
To Make The Beef Gravy
Start heating the beef juices and fat over a high heat.
Add 400ml Water to the pan. Freshly boiled from the kettle will speed up the process.
Mix 3 tbsp Cornflour with roughly 3 tbsp Wateruntil all the cornflour has dissolved.
Once the juices and water have come to the boil, add the cornflour slurry with one hand while whisking with the other.
Continue to boil until the gravy is thickened. If after a few minutes, it is not thick enough for your liking, make up and add more cornflour slurry - add a little at a time. If it is thicker than you would like, add a little water at a time.
Taste the gravy and add Sea Salt Flakes a little at a time until the gravy is flavoursome. Don't be shy, salt is your friend with gravy.
Pour into a jug and serve with the sliced beef.
Notes
The air fryer version of this recipe is tested in a Cosori Lite 3.8L (CAF-LI401S) which has a square(ish) shaped basket of 21cm x 21cm and 24cm on the diagonal. The depth of the basket is more of an important consideration in this case.
Not all models advise preheating is required. Please follow the recommended instructions for your model. Mine has a specific preheat setting which is 4 minutes at 205c.
For this recipe, I could easily fit in up to a 1kg beef topside in the basket.
As all air fryer models are a little different, you may find that you can fit more or less in at a time.
Required cooking times and temperatures can also vary between models and brands. If you know that your air fryer runs a little hotter than most recipes suggest, use a lower temperature. And vice versa. Equally if you find that food cooks more quickly in your machine than instructions usually state, reduce the cooking time (or check it earlier) and vice versa.
