Cooking London broil in an air fryer oven is a game-changer for busy home cooks. This lean, flavorful cut of beef becomes tender and delicious with minimal effort, thanks to the air fryer’s rapid hot air circulation. With the right marinade, timing, and technique, you can enjoy restaurant-quality results in under 30 minutes.
Key Takeaways
- London broil is not a specific cut but a cooking method: It usually refers to top round or flank steak, marinated and grilled or broiled.
- Air fryer ovens cook London broil faster than ovens: Expect 15–20 minutes total time, depending on thickness and desired doneness.
- Marinating is essential for tenderness: Use acidic ingredients like vinegar or citrus, plus herbs and garlic, for at least 2 hours (or overnight).
- Pat the meat dry before cooking: This ensures a better sear and prevents steaming in the air fryer.
- Let it rest after cooking: Resting for 5–10 minutes keeps juices inside, making each slice more flavorful.
- Slice against the grain: This breaks up muscle fibers, ensuring every bite is tender.
- Use a meat thermometer for accuracy: Target 130–135°F for medium-rare; carryover cooking will raise the temperature slightly.

What Is London Broil?
Despite its name, London broil isn’t a specific cut of beef—it’s actually a cooking method. Traditionally, it refers to a lean, relatively tough cut like top round, bottom round, or flank steak that’s marinated, cooked quickly over high heat, and then sliced thinly against the grain. The result? A flavorful, satisfying steak that’s budget-friendly and perfect for weeknight dinners.
Because these cuts are less tender than ribeye or filet mignon, they benefit greatly from marination and proper cooking techniques. That’s where the air fryer oven shines. Unlike conventional ovens or grills, air fryer ovens use rapid hot air circulation to cook food evenly and quickly, creating a delicious crust while keeping the inside juicy. This makes it an ideal appliance for cooking London broil without drying it out.
Why Cook London Broil in an Air Fryer Oven?
The air fryer oven has revolutionized home cooking, and London broil is one of the meats that benefits most from this technology. Unlike slow roasting or grilling, which can take over an hour, air frying reduces cooking time significantly—often by half. Plus, you get that coveted caramelized exterior without needing to stand over a hot grill or preheat a large oven.
Another advantage? Cleanup is a breeze. There’s no splattered grease or charred grill grates to scrub. Just place your marinated steak on the air fryer rack, set the timer, and walk away. The consistent heat distribution ensures even cooking, reducing the risk of overcooked edges or undercooked centers. And because air fryer ovens are compact, they’re perfect for small kitchens or anyone looking to save energy.
Air Fryer vs. Traditional Methods
Compared to broiling in a conventional oven, air frying is faster and more energy-efficient. Broiling can take 20–30 minutes and requires close monitoring to avoid burning. Grilling adds great flavor but isn’t always practical in bad weather or apartment living. Pan-searing gives a nice crust but can leave the interior underdone if not timed perfectly.
The air fryer oven combines the best of all worlds: speed, convenience, and consistent results. It mimics the high-heat environment of grilling while using less oil and producing less smoke. For anyone who loves steak but hates the hassle, this method is a total win.
Choosing the Right Cut of Meat
Since “London broil” isn’t a cut, you’ll need to know what to look for at the butcher counter or grocery store. The most common options are top round and flank steak. Both are lean, affordable, and respond well to marination.
Top round is slightly more tender and has a finer grain, making it easier to slice thinly. Flank steak has more pronounced muscle fibers and a beefier flavor, but it must be sliced correctly to avoid chewiness. Avoid cuts like sirloin or chuck—they’re better suited for slow cooking.
What to Look For When Buying
- Thickness: Aim for 1 to 1.5 inches thick. Thinner cuts may overcook; thicker ones may not cook through evenly.
- Marbling: While London broil isn’t known for marbling, a little fat can add flavor. Look for even color and minimal connective tissue.
- Freshness: Choose meat that’s bright red with no gray spots. If buying pre-packaged, check the sell-by date.
If you’re unsure, ask your butcher for a “London broil cut”—they’ll typically give you a top round steak ready for marinating.
Marinating for Maximum Flavor and Tenderness
Marinating is non-negotiable when cooking London broil. These lean cuts lack the natural fat that keeps richer steaks moist, so a good marinade does double duty: it adds flavor and helps break down tough muscle fibers.
A basic marinade includes three key components: an acid (like lemon juice, vinegar, or yogurt), oil (to carry fat-soluble flavors), and seasonings (garlic, herbs, salt, and pepper). Let the meat marinate for at least 2 hours, but overnight is even better. The longer it sits, the more tender and flavorful it becomes.
Simple Marinade Recipe
- ¼ cup olive oil
- 3 tablespoons soy sauce
- 2 tablespoons balsamic vinegar
- 2 cloves garlic, minced
- 1 tablespoon Dijon mustard
- 1 teaspoon black pepper
- 1 teaspoon dried oregano or rosemary
Whisk everything together, pour over the steak in a resealable bag or shallow dish, and refrigerate. Turn the meat occasionally to ensure even absorption.
Tips for Better Marination
- Don’t over-marinate: More than 24 hours can make the meat mushy, especially with strong acids like vinegar.
- Pierce the meat lightly: Use a fork to create small holes, helping the marinade penetrate deeper.
- Pat dry before cooking: Excess moisture prevents browning. Always dry the surface with paper towels before air frying.
Step-by-Step Guide to Cooking London Broil in an Air Fryer Oven
Now for the fun part—cooking! Follow these simple steps for a perfectly cooked London broil every time.
Step 1: Prep the Air Fryer
Preheat your air fryer oven to 400°F (200°C). Preheating ensures a quick sear and even cooking. While it heats, remove the marinated steak from the fridge and let it sit at room temperature for 15–20 minutes. This reduces cooking time and prevents cold centers.
Step 2: Season and Arrange
Pat the steak completely dry with paper towels. Lightly brush both sides with a little oil (optional, but helps with browning). Season with salt and pepper if desired—though the marinade likely already contains salt.
Place the steak on the air fryer rack or in the basket, leaving space around it for air circulation. Do not overcrowd. If your air fryer is small, cook one steak at a time.
Step 3: Cook to Perfection
Cook at 400°F for 12–16 minutes, flipping halfway through. Use a meat thermometer to check internal temperature:
– 125°F = rare
– 130–135°F = medium-rare (recommended)
– 140–145°F = medium
Remember, the temperature will rise 5°F during resting. For a 1-inch thick steak, 14 minutes usually yields medium-rare. Thicker cuts may need 16–18 minutes.
Step 4: Rest and Slice
Transfer the steak to a cutting board and tent loosely with foil. Let it rest for 5–10 minutes. This allows juices to redistribute, ensuring every bite is moist.
When ready to serve, slice against the grain—this means cutting perpendicular to the muscle fibers. Look for the direction of the lines in the meat and slice across them. Thin slices (¼-inch thick) are ideal.
Serving Suggestions and Pairings
London broil is incredibly versatile. Serve it as a main course with roasted vegetables, mashed potatoes, or a fresh salad. It also makes excellent leftovers—use sliced London broil in sandwiches, tacos, or stir-fries the next day.
For a complete meal, pair it with:
- Garlic mashed potatoes
- Air-fried asparagus or broccoli (try our how to cook broccoli in air fryer guide)
- A simple arugula salad with lemon vinaigrette
- Crusty bread to soak up the juices
If you’re meal prepping, cook a larger cut and slice it for easy lunches throughout the week. Store in an airtight container in the fridge for up to 4 days.
Common Mistakes to Avoid
Even with the best recipe, small mistakes can ruin your London broil. Here’s what to watch out for:
- Skipping the marinade: Without it, the meat will be tough and bland.
- Not preheating the air fryer: This leads to uneven cooking and a lack of browning.
- Overcooking: London broil dries out quickly. Use a thermometer and aim for medium-rare.
- Slicing with the grain: This makes the meat chewy. Always cut against the grain.
- Cutting too soon: Resting is crucial. Don’t skip it!
By following these tips, you’ll avoid the pitfalls and enjoy a tender, flavorful steak every time.
