How to Cook London Broil in an Air Fryer Oven?
London broil, a flavorful and relatively lean cut of beef, can be cooked to perfection in an air fryer oven. The key is proper preparation, including marinating for enhanced tenderness and flavor, and utilizing the air fryer’s efficient heat circulation to achieve a beautifully seared exterior with a juicy, medium-rare center.
Understanding London Broil
London broil isn’t a specific cut but rather refers to the preparation method for tougher cuts of beef, typically top round or flank steak. Traditionally, it involves marinating, broiling (hence the name), and then slicing thinly against the grain. Air frying provides a modern, faster, and arguably more convenient alternative to traditional broiling.
Benefits of Air Frying London Broil
Air frying offers several advantages over traditional cooking methods for London broil:
- Speed: Air fryers cook faster due to the concentrated heat and circulating air.
- Even Cooking: The consistent airflow promotes even browning and cooking throughout the steak.
- Crispy Exterior: Achieves a desirable seared crust similar to grilling, but indoors.
- Less Oil: Requires minimal oil, making it a healthier option.
- Easy Cleanup: Air fryer baskets are generally easy to clean.
Preparing Your London Broil
Successful air fryer London broil begins with proper preparation:
- Choose the Right Cut: Opt for top round or flank steak, typically about 1-1.5 inches thick.
- Marinate: Marinating is crucial for tenderizing and adding flavor. A minimum of 2 hours, but preferably overnight, is recommended. Consider a marinade consisting of:
- Olive Oil
- Soy Sauce or Worcestershire Sauce
- Balsamic Vinegar or Red Wine Vinegar
- Garlic (minced)
- Onion Powder
- Black Pepper
- Optional: Dijon Mustard, Red Pepper Flakes, Fresh Herbs (Rosemary, Thyme)
- Bring to Room Temperature: Remove the marinated steak from the refrigerator about 30 minutes before cooking. This allows for more even cooking.
- Pat Dry: Before air frying, pat the steak dry with paper towels. This promotes better browning.
Air Frying Process: Step-by-Step
Follow these steps for perfect air fryer London broil:
- Preheat: Preheat your air fryer oven to 400°F (200°C).
- Lightly Oil: Lightly spray the air fryer basket with cooking oil.
- Place the Steak: Place the steak in the air fryer basket, ensuring it’s not overcrowded. Overcrowding will steam the steak rather than sear it.
- Cook: Air fry for approximately 5-7 minutes per side for medium-rare (130-135°F). Adjust cooking time based on the thickness of the steak and your desired level of doneness. Use a meat thermometer to ensure accuracy.
- Rest: Crucially important! Remove the steak from the air fryer and let it rest for 10-15 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful steak. Tent loosely with foil.
- Slice: Slice the steak thinly against the grain. This shortens the muscle fibers, making it easier to chew.
Temperature Guide for London Broil
| Doneness | Internal Temperature |
|---|---|
| Rare | 125-130°F (52-54°C) |
| Medium Rare | 130-135°F (54-57°C) |
| Medium | 135-145°F (57-63°C) |
| Medium Well | 145-155°F (63-68°C) |
| Well Done | 155°F+ (68°C+) |
- Note: The internal temperature will continue to rise slightly during resting (carryover cooking).
Common Mistakes to Avoid
- Skipping the Marinade: Marinating is essential for tenderizing.
- Overcrowding the Air Fryer: Overcrowding leads to steaming instead of searing.
- Overcooking: Use a meat thermometer to avoid overcooking. London broil is best enjoyed medium-rare to medium.
- Skipping the Resting Period: Resting allows the juices to redistribute, resulting in a more tender steak.
- Not Slicing Against the Grain: Slicing with the grain results in a tough, chewy steak.
Frequently Asked Questions (FAQs)
Can I use frozen London broil in the air fryer?
While not recommended, you can cook frozen London broil in the air fryer. However, you will need to adjust the cooking time significantly and the texture may be less desirable compared to cooking from thawed. Thawing is always the preferred method.
What temperature should I set my air fryer to for cooking London broil?
400°F (200°C) is the ideal temperature for air frying London broil. This high temperature promotes a nice sear while cooking the inside to your desired level of doneness.
How long does it take to cook London broil in an air fryer oven?
Cooking time varies depending on the thickness of the steak and your desired level of doneness. Generally, it takes about 5-7 minutes per side for medium-rare for a 1-inch thick steak. Always use a meat thermometer to ensure accuracy. Remember the steak will continue to cook while resting.
Do I need to flip the London broil while it’s air frying?
Yes, flipping the London broil halfway through cooking ensures even cooking and browning on both sides.
What kind of oil should I use in the air fryer?
Any cooking oil with a high smoke point is suitable, such as avocado oil, canola oil, or vegetable oil. Lightly spray the air fryer basket to prevent sticking.
Can I add vegetables to the air fryer along with the London broil?
Yes, you can add vegetables to the air fryer during the last 10-15 minutes of cooking. Good choices include broccoli, asparagus, bell peppers, and onions. Toss the vegetables with olive oil, salt, and pepper before adding them to the air fryer.
How do I store leftover London broil?
Allow the cooked London broil to cool completely before storing it in an airtight container in the refrigerator. It will keep for up to 3-4 days.
How do I reheat London broil?
Reheat leftover London broil in the air fryer at a lower temperature (around 300°F or 150°C) to prevent it from drying out. Reheating time will vary depending on the thickness of the slices. You can also reheat it in a skillet with a little bit of oil or in the microwave, but these methods may result in a less desirable texture.
What are some good side dishes to serve with London broil?
London broil pairs well with a variety of side dishes, including roasted vegetables, mashed potatoes, baked potatoes, rice, salad, and steamed green beans.
Can I use dry rub instead of marinade?
While a marinade is preferred for tenderizing, a dry rub can certainly be used for added flavor. Apply the dry rub generously to the steak at least 30 minutes before cooking.
My London broil is tough. What did I do wrong?
The most common causes of tough London broil are insufficient marinating, overcooking, and slicing with the grain. Ensure you marinate the steak for an adequate amount of time, cook it to the correct internal temperature, and slice it thinly against the grain.
Is air frying London Broil healthy?
Yes, air frying can be a healthier way to cook London broil. It requires significantly less oil than deep frying or pan-frying, and it helps to render out excess fat from the steak. As long as you’re using a leaner cut and a healthful marinade, it can be a delicious and healthy protein option.
