1. Make the marinade: In a small bowl, mix together olive oil, minced garlic, dried thyme, paprika, salt, and pepper until it forms a fragrant paste. Don’t skip the mixing—you want all those flavors evenly distributed.
2. Marinate the meat: Place your London broil in a shallow dish or large zip-top bag. Rub the spice mixture all over both sides of the meat, really working it into the surface with your hands. Cover the dish with plastic wrap or seal the bag, squeezing out excess air. Refrigerate for at least 2 hours, though 8-12 hours (overnight) is ideal for maximum flavor and tenderness.
3. Bring to room temperature: About 30 minutes before cooking, remove the meat from the fridge and let it sit on the counter. This helps it cook more evenly—cold meat straight from the fridge can char outside while staying raw inside.
4. Preheat your grill: Crank your grill to medium-high heat (about 400-450°F) and let it get nice and hot. You want those grates hot enough that water droplets sizzle immediately. Oil the grates lightly to prevent sticking.
5. Grill the meat: Place the London broil on the hot grill and close the lid. Cook for 6-8 minutes without moving it—this develops that gorgeous crust. Flip it once and cook another 6-8 minutes for medium-rare (130-135°F internal temperature). Use an instant-read thermometer inserted into the thickest part—trust the thermometer, not the timer, since every grill is different.
6. Rest before slicing: This is crucial! Remove the meat from the grill and transfer it to a cutting board. Tent loosely with foil and let it rest for 10 full minutes. This lets the juices redistribute so they don’t all run out when you slice—if you can resist cutting right away.
7. Slice against the grain: Here’s the secret to tender London broil: look at the direction the muscle fibers run (the “grain”) and slice perpendicular to those lines, creating thin slices about 1/4 inch thick. Cut on a slight diagonal for prettier presentation. Serve immediately while it’s still warm and watch it disappear!

Notes:

• Don’t skip the resting period. Those 10 minutes make the difference between juicy and dry meat. The juices need time to redistribute.
• Use an instant-read thermometer. Every grill runs differently, so trust your thermometer: 130-135°F for medium-rare, 135-145°F for medium. Past 145°F and London broil gets tough.
• Slice against the grain—seriously. This is the single most important step for tender London broil. If you’re not sure which direction is against the grain, hold up a slice and look—if you see short fibers, you did it right. If you see long stringy fibers, rotate your cutting angle 90 degrees.
• Room temperature matters. Cold meat from the fridge cooks unevenly. Those 30 minutes on the counter are worth the wait.
• For oven cooking: Broil 4-6 inches from heat for 6-8 minutes per side, or reverse-sear (roast at 275°F to 120°F internal, then sear in hot pan).

Storage Tips:

Store leftover London Broil sliced or whole in an airtight container in the refrigerator for up to 4 days. It’s fantastic cold on sandwiches with horseradish mayo or sliced over salads. For reheating, use a low oven (250°F) just until warmed through, or quickly sear in a hot pan—don’t microwave or it’ll toughen up. You can freeze cooked London broil wrapped tightly in plastic wrap and foil for up to 3 months, though the texture will be slightly less tender when thawed. Thaw overnight in the fridge before reheating.

Serving Suggestions:

• Classic steakhouse style: Serve with baked potatoes, creamed spinach, and sautéed mushrooms
• Fresh and light: Pair with grilled asparagus, garden salad, and garlic bread
• Sandwich heaven: Slice thin and pile on crusty bread with caramelized onions, arugula, and horseradish sauce
• Bowl-style: Serve over rice or quinoa with roasted vegetables and chimichurri sauce

Mix It Up (Recipe Variations):

• Balsamic London Broil: Add 2 tablespoons balsamic vinegar and 1 tablespoon Worcestershire sauce to the marinade for tangy, complex flavor.
• Herb-Crusted London Broil: Mix in 1 tablespoon fresh rosemary, 1 tablespoon fresh oregano, and 1 teaspoon Dijon mustard for an elegant, herb-forward version.
• Spicy Southwest London Broil: Use smoked paprika, add 1 teaspoon cumin and 1/4 teaspoon cayenne pepper, then serve with chimichurri or cilantro-lime sauce.
• Asian-Inspired London Broil: Replace thyme with 1 tablespoon grated fresh ginger, add 2 tablespoons soy sauce to the marinade, and finish with toasted sesame seeds.

What Makes This Recipe Special:

This London Broil perfectly demonstrates how proper technique transforms an affordable cut into steakhouse-quality results. The simple marinade penetrates and tenderizes the meat, high-heat grilling creates a flavorful crust while keeping the interior juicy, and slicing against the grain ensures every bite is tender rather than chewy—these three elements are what separate tough London broil from restaurant-worthy perfection.
