Optimal Cooking Times and Temperatures for London Broil in an Air Fryer

When cooking London Broil in an air fryer, achieving the perfect balance between tenderness and flavor relies heavily on precise timing and temperature control. Since London Broil is typically a lean cut of beef, it benefits from quick, high-heat cooking to avoid drying out while still allowing a desirable sear.

For best results, preheat your air fryer to a temperature between 375°F and 400°F. This range encourages the Maillard reaction, which develops a flavorful crust on the surface while sealing in juices. The cooking time will vary depending on the thickness of the steak and your preferred level of doneness.

Below is a general guideline for cooking a 1-inch thick London Broil steak in an air fryer:

Doneness Level Internal Temperature (°F) Cooking Time (minutes) Flip Frequency
Rare 125 6-7 Flip halfway (at 3-3.5 min)
Medium Rare 135 8-9 Flip halfway (at 4-4.5 min)
Medium 145 10-11 Flip halfway (at 5-5.5 min)
Medium Well 150 12-13 Flip halfway (at 6-6.5 min)
Well Done 160+ 14-15 Flip halfway (at 7-7.5 min)

Keep in mind that air fryer models vary, so it’s advisable to use a reliable instant-read meat thermometer to monitor the internal temperature for precise doneness. Additionally, flipping the steak halfway through cooking ensures even heat distribution and a consistent crust.

Tips for Preparing London Broil Before Air Frying

Proper preparation of London Broil prior to air frying enhances both texture and taste. Consider the following expert tips:

  • Marinate for tenderness: London Broil is often tougher than other cuts due to muscle fibers. Marinating it for at least 2 hours (or overnight) with acidic ingredients like vinegar, citrus juice, or wine helps break down connective tissue and infuses flavor.
  • Pat dry before cooking: Excess moisture on the steak surface can inhibit browning and cause steaming. After marinating, pat the steak dry with paper towels to promote a crispy crust.
  • Season adequately: Even after marinating, season the steak lightly with salt and pepper or your preferred dry rub to complement the marinade flavors.
  • Bring steak to room temperature: Allow the steak to rest outside the refrigerator for 20-30 minutes before air frying. This step promotes even cooking throughout the meat.
  • Trim excess fat: While some fat adds flavor, trimming thick fat layers reduces flare-ups and uneven cooking in the air fryer.

Resting and Serving London Broil After Air Frying

Once the London Broil has reached the desired internal temperature, it’s crucial to rest the steak before slicing. Resting allows the muscle fibers to reabsorb juices displaced during cooking, resulting in a juicier final product.

  • Tent the steak loosely with aluminum foil.
  • Rest for 5 to 10 minutes depending on thickness.
  • Slice thinly against the grain to maximize tenderness.

Serving suggestions include pairing London Broil with roasted vegetables, a fresh salad, or a robust sauce such as chimichurri or a red wine reduction. Proper resting and slicing enhance the eating experience by ensuring each bite is flavorful and tender.

Optimal Cooking Time and Temperature for London Broil in an Air Fryer

Cooking London broil in an air fryer offers a quick and efficient way to achieve a tender, flavorful steak with a desirable crust. The exact cooking time depends on the thickness of the cut and your preferred level of doneness.

For a London broil approximately 1 to 1.5 inches thick, the following guidelines apply:

Doneness Level Air Fryer Temperature Cooking Time (per side) Total Cooking Time
Rare (125°F internal) 400°F (204°C) 4 minutes 8 minutes
Medium Rare (135°F internal) 400°F (204°C) 5 minutes 10 minutes
Medium (145°F internal) 400°F (204°C) 6 minutes 12 minutes
Medium Well (150°F internal) 400°F (204°C) 7 minutes 14 minutes
Well Done (160°F+ internal) 400°F (204°C) 8 minutes 16 minutes

Key Factors Affecting Cooking Time

  • Steak Thickness: Thicker cuts require longer cooking times. Adjust times accordingly if the London broil is thicker than 1.5 inches.
  • Air Fryer Model: Variations in wattage and airflow can impact cooking speed; always monitor progress closely the first time.
  • Initial Meat Temperature: Starting with room temperature meat ensures even cooking and prevents undercooked centers.
  • Desired Doneness: Use a reliable meat thermometer to check internal temperature for precise results.

Preparation and Cooking Tips for Best Results

Proper preparation enhances the flavor and texture of London broil cooked in an air fryer. Follow these expert recommendations:

  • Marinate Prior to Cooking: London broil benefits greatly from marination, which helps tenderize the meat and infuse flavor. Use a marinade with acidic components such as vinegar, citrus juice, or wine for at least 2 hours or overnight.
  • Pat Dry Before Air Frying: Remove excess marinade and pat the steak dry with paper towels to promote browning and crisping.
  • Preheat the Air Fryer: Preheating to 400°F ensures immediate searing and optimal crust formation.
  • Use a Light Coating of Oil: Brush both sides lightly with a high smoke point oil (e.g., avocado or canola oil) to enhance browning without excessive smoke.
  • Flip Halfway Through: Turning the steak halfway through cooking promotes even heat distribution and consistent doneness.
  • Rest the Meat Post-Cooking: Allow the steak to rest for 5 to 10 minutes after air frying to redistribute juices and improve tenderness.

Using a Meat Thermometer for Precision

Achieving the perfect London broil requires monitoring internal temperature accurately. Follow these guidelines:

  • Insert the thermometer probe into the thickest part of the steak, avoiding fat or bone.
  • Remove the steak from the air fryer when it is 5°F (3°C) below your target temperature to account for carryover cooking during resting.
  • Recommended internal temperatures for London broil:
  • Rare: 125°F (52°C)
  • Medium Rare: 135°F (57°C)
  • Medium: 145°F (63°C)
  • Medium Well: 150°F (66°C)
  • Well Done: 160°F (71°C) and above

Adjusting Cooking Time for Different Thicknesses and Sizes

London broil steaks vary in thickness, and cooking times must be adjusted accordingly. Use the following multiplier to estimate cooking times based on thickness:

Steak Thickness Multiplier for Cooking Time
Up to 1 inch 0.75×
1 to 1.5 inches (standard) 1× (base time)
1.5 to 2 inches 1.25×
Over 2 inches 1.5× or more (monitor closely)

For example, if a 1-inch steak requires 8 minutes total for medium rare, a 1.75-inch steak would require approximately 10 minutes (8 × 1.25).

Additional Considerations for Air Frying London Broil

  • Avoid Overcrowding: Cook one steak at a time or leave sufficient space around the meat for proper air circulation.
  • Use the Air Fryer Basket or Rack: Elevating the steak promotes even heat exposure and allows fat to drip away.
  • Check for Doneness Early: Begin checking the internal temperature a minute or two before the minimum recommended time to prevent overcooking.
  • Consider Carryover Cooking: Residual heat will raise the
