This easy Air fryer London broil turns out tender and juicy every time with a delightful crust you just can’t get from the oven. And there’s no marinade needed!
London broil is one of those dishes people either love or hate. When it’s not cooked properly, top round can turn out tough and flavorless, so I understand why some are a little skeptical.
But let me tell you, this air fryer London broil is changing the game!
The meat turns out tender and juicy every time while the outside gets a delightful crust you just can’t get from trying to roast it in the oven.
Best of all, it’s ready in 25 minutes, no marinade necessary. Just use your favorite seasoning or rub for London Broil and let the air fryer do the rest.

- How to store and reheat leftover London Broil
The taste and texture of this dish is absolutely worthy of a special occasion, yet it’s so easy to make.
And because top round is a less expensive cut of beef, it ends up being a very budget-friendly meal, too!

A full printable version of this recipe with ingredient measurements is available at the bottom of this post.
STEP ONE: Preheat your air fryer to 400 degrees.
STEP TWO: Rub the beef down with oil, then sprinkle with Montreal steak seasoning.
STEP THREE: Place the London broil in the preheated air fryer and cook for 8-10 minutes until the meat reaches your desired doneness (115-120 degrees F for medium-rare).
STEP FOUR: Remove the roast from the air fryer and allow it to rest for 10 minutes before serving.
What Temperature Should I Cook London Broil To?
The internal temperature you cook your meat to is what we refer to as “doneness.” Whether your beef turns out red, pink, or grey in the center will all depend on that internal temperature.
In this recipe, I recommend cooking your London Broil for 8-10 minutes until it reaches about 115 degrees F for a medium-rare cut of beef.
For medium doneness, keep cooking until the meat reaches about 145 degrees F. For well done, you’ll want an internal temperature of 160 degrees F.
Keep in mind that the total cooking time is going to depend on the size of your top round.
As you can imagine, a 1-pound cut is going to cook faster than a 2-pound cut.
I always recommend using an Instant-Read Meat Thermometer to check for doneness to make sure your meat is tender every time.

How to Store Leftover London Broil
If you find yourself with extra London broil, you’re in luck! This cut of meat makes fantastic leftovers that you can enjoy throughout the week.
You can choose to cut your London broil into slices or leave it as a whole slab.
I recommend wrapping tightly in plastic wrap and aluminum foil or placing the meat in an airtight container.
Store in the refrigerator for up to four days.
Can I Choose to Marinate the London Broil Instead?
If you prefer to marinate your London broil, you can skip the seasonings listed and use your favorite option instead!
If you’re looking for recommendations, one of my favorite store-bought marinades is Lawry’s Teriyaki with Pineapple Juice.
Why is my London Broil so Tough?
London broils get a bad reputation for turning out tough. It’s a leaner cut of meat with low-fat content, which means you have to get the cooking method just right.
Thankfully, when you’re cooking London broil in the air fryer, you don’t have to worry! The circulation of hot air keeps the beef from drying out so that it stays wonderfully tender and juicy.
