Air fryers are a quick and easy way to cook a roast, producing a tender and juicy roast with a beautifully caramelized crust. While roast beef is traditionally cooked in an oven, air fryers can produce the same delicious results in a fraction of the time. The key to a perfect roast is achieving a balance between a dark caramelized outer crust and a juicy pink inside. This can be done by cooking the roast at a high temperature to create a crust, and then lowering the temperature to cook the beef slowly, ensuring it remains moist and juicy.

Choosing the right cut of beef
When it comes to choosing the right cut of beef for slow cooking in an air fryer, there are a few things to keep in mind. Firstly, consider the amount of fat in the meat. Fattier cuts of beef are good for slow cooking as the fat helps to keep the meat moist and adds flavour. Look for good marbling—a flecked, speckled appearance of fat within the meat—but avoid cuts with too much exterior fat.
Next, consider the connective tissue in the meat. Cuts with a lot of connective tissue, such as the shank, taken from the lower leg of the animal, will need to be cooked slowly to become tender. The chuck, a budget-friendly cut from the shoulder area, is also a hard-working muscle that benefits from slow cooking.
For air fryer roast beef, it is recommended to choose a tender cut of beef with some marbling. Top sirloin roast, prime rib roast, rump roast, and top-round roast are all good options. If you're looking for a leaner cut of meat, go for a sirloin tip roast, top round roast, or ribeye roast. Keep in mind that the size and type of roast will impact the cooking time, so choose a cut that fits well in your air fryer.
If you're looking for a cheaper option, consider the flat, which is the other half of the brisket cut. It is more suited to thin slicing or shredding. Oxtail, a traditional cheap cut, has also gained popularity in recent years. It is loaded with fat, cartilage, and marrow that becomes incredibly flavoursome when slow-cooked.

Preparing the roast
After this, season the roast. You can use salt and pepper, or get creative with herbs and spices. Some suggestions include rosemary, thyme, garlic powder, and oregano. You can also add an onion to the air fryer with the beef for extra flavor. Once the roast is seasoned, place it in the air fryer basket. If you're cooking vegetables with the roast, place them in a cake pan first, then put the beef joint on top before placing the pan in the air fryer basket.
Now it's time to cook the roast. Preheat your air fryer to between 350°F and 400°F (180°C to 200°C). The exact temperature will depend on your air fryer and personal preference. Cook the roast for 10 to 15 minutes at this high temperature to create a crust, then reduce the heat to 350°F / 180°C and cook for an additional 30 minutes. If you're cooking vegetables, you can add them to the air fryer now and cook them for about 20 minutes.

Cooking the roast
Preheat your air fryer to a high temperature of around 380–400 °F (180°C). Place the roast in the air fryer basket and cook for 10–15 minutes to form a crust. Then, reduce the temperature to 350 °F (180 °C) and cook for an additional 30 minutes, flipping the roast halfway through. For a 2–3 lb roast, this should take around 40–42 minutes in total. If you are cooking a larger roast, you can use the rule of thumb of 13 minutes per pound, plus an additional five minutes for how well done you want it.
To check if the roast is done to your liking, use a meat thermometer to gauge the internal temperature. For rare or medium-rare, aim for an internal temperature of 130–134 °F (55–57 °C). When the roast is almost at your desired temperature, remove it from the air fryer and let it rest on a cutting board for 10–30 minutes. This allows the juices to redistribute and the meat fibers to relax, resulting in a juicier and more tender roast. Finally, slice the roast and serve with your favorite side dishes.

Resting the roast
While the roast is resting, you can continue to cook any vegetables or sides that you may be serving alongside. For example, you can cook potatoes, carrots, and other vegetables in a separate container in the air fryer while the roast rests. You can also use this time to make a gravy using the pot roast juices.
It is important to note that the temperature of the roast will continue to rise slightly as it rests. Therefore, it is recommended to remove the roast from the air fryer just before it reaches your desired temperature. This will ensure that the roast is cooked to your liking and prevent overcooking.
Additionally, the resting period allows you to clean and prepare your workspace for slicing and serving the roast. Gather a sharp knife and a serving platter or plates. When the resting time is complete, slice the roast against the grain to ensure maximum tenderness.
By following these steps and allowing the roast to rest adequately, you will be able to serve a juicy and tender roast cooked to perfection in your air fryer.

Serving the roast
Once your roast is cooked to your liking, it's time to serve it! Place the roast on a warm platter and cover it loosely with foil. It is important to let the roast rest for 20 to 30 minutes before slicing and serving. This allows the juices to redistribute throughout the meat, making it moist and juicy. It also gives the muscle fibers time to relax, resulting in a more tender roast.
While the roast is resting, you can prepare your side dishes. Some classic side dishes to consider are roast potatoes, mashed potatoes, green bean casserole, braised red cabbage, creamy sprouts with bacon, or roasted butternut squash salad. For a true British experience, don't forget to include some Yorkshire puddings!
When you're ready to serve, slice the roast against the grain for the most tender slices. Arrange the roast beef slices on a platter, surrounded by your chosen side dishes. Don't forget to drizzle the platter with the delicious juices that have accumulated while the roast was resting.
For a picture-perfect presentation, garnish the platter with fresh herbs like rosemary or thyme. You can also add a few pats of butter on top of the roast beef to enhance its juiciness and flavor.
Now, simply enjoy your delicious air fryer roast with your family and friends!
