Tender London Broil

I love a recipe that looks fancy on a plate but is basically forgiving chaos in the kitchen — that’s this London broil for me. Big, bold-flavored marinade, seared until the edges get that lovely crust, then sliced thin so even a tougher cut feels tender. It’s the kind of weeknight dinner that also makes killer leftovers for sandwiches, salads, or a no-shame midnight snack.

My little family eats this like it’s a holiday. My husband will literally hover by the oven and ask, every single time, “Can we just eat it raw?” (No, babe — but good try.) The kids love when I slice it super thin and pile it on buttered rolls. Once I forgot to marinate it long enough and we all pretended we liked it — eventually I marinated the leftovers overnight and it was a different animal. Now it’s become our Sunday dinner that stretches into lunches and late-night bites.

I once panicked and flipped the steak every 30 seconds like a short-order cook — not necessary and wildly overcooked. The trick that saved me: get a good crust quickly over high heat, then back off a touch so the middle doesn’t dry out. I’ve also winged a marinade with pantry odds and ends (soy + mustard + a sweetener + acid) and somehow it always turns out okay. Oh and slicing against the grain? Non-negotiable. There’s nothing more disappointing than a chewy slice because you sliced with the grain.

Shopping Tips

– Protein: Look for flank or top round labeled London broil; choose a uniform thickness for even cooking.
– Spices: Use coarse-ground black pepper and kosher salt if possible — they give a better crust than fine table salt.
– Fresh Herbs: Parsley, thyme, or rosemary brighten up the marinade; buy a small bunch and use what you can.
– Fats & Oils: Use a neutral oil with a high smoke point for searing, and save a little olive oil to finish if you like.
– Citrus: A lemon or two is handy for finishing; fresh juice wakes the whole dish up compared to bottled.

Prep Ahead Ideas

– Marinate the steak the night before in a zip-top bag so the flavors really sink in; it also saves time the day you cook.
– Slice onions, mince garlic, and mix the dry rub or marinade in advance and store in a small jar in the fridge.
– Keep the marinating steak in a shallow dish or bag on the bottom shelf of the fridge to avoid drips.
– If you want to serve with a chimichurri or quick herb sauce, make it the morning of so the flavors meld but it stays bright.

Time-Saving Tricks

– Use a broiler or a screaming-hot cast-iron pan to get a crust fast — less time standing at the stove.
– Make a double batch of the marinade and keep some in the fridge for another week of quick steaks.
– Thin-slice leftovers and toss on a salad instead of warming the whole steak; it’s fast and less fussy.
– Don’t rush the rest after cooking — a short 5–10 minute rest improves juiciness thanks to carryover cooking.

Common Mistakes

– Overcooking because you left it under a fat broiler too long; solution: watch the edges and use visual cues, not only time.
– Cutting too early — I once sliced immediately and all the juices ran out; let it rest to keep things juicy.
– Slicing with the grain (guilty!) — that makes even a nice steak feel chewy; flip your brain and cut across the fibers.
– Using too much acid in the marinade for too long — it can “cook” the surface and make it mushy; balance is key.

What to Serve It With

– Roasted garlic mashed potatoes or simple buttered noodles for ultimate comfort.
– A crisp green salad or quick slaw to cut the richness.
– Grilled veggies or charred broccoli for smoky contrast.
– Crusty bread and honey-butter for sopping up juices.

Tips & Mistakes

– Sear hot, then finish gentler — that crust is worth standing over the pan for a minute.
– Salt at least 30 minutes before cooking (or right before searing) to avoid a dry interior.
– If the steak is stubbornly tough, slice paper-thin and serve with a sauce to mask the chew.
– Forgot to rest? Tent with foil for 5 minutes so the juices redistribute.

Storage Tips

Leftovers live well in an airtight container in the fridge for 3–4 days. Cold slices on a sandwich are basically a weekday flex — no shame. To reheat, warm gently in a skillet with a splash of broth or butter so it doesn’t dry out, or briefly under the broiler. Steak for breakfast? Yes: chop it, throw it in a skillet with eggs — instant hero.

Variations and Substitutions

Flank or top round both work; hanger steak is a tastier splurge. Swap soy for tamari if you want gluten-free, and honey or brown sugar in place of syrup for caramel notes. If you like a smoky vibe, finish on the grill or add a dash of smoked paprika. Heavy with acid? Cut the marinating time back next time. Tried it with a coffee rub once — weird but surprisingly delicious.

Ingredients

 

1x2x3x

Steak

• ▢ 2 pounds London broil (top round or sirloin)
• ▢ 2 tablespoons fresh parsley, chopped

Marinade

• ▢ 6 tablespoons olive oil
• ▢ 1/4 cup low-sodium soy sauce
• ▢ 3 tablespoons Worcestershire sauce
• ▢ 3 tablespoons fresh lemon juice
• ▢ 1 teaspoon lemon zest
• ▢ 2 teaspoons Dijon mustard
• ▢ 1 teaspoon light brown sugar
• ▢ 2 cloves garlic, minced
• ▢ 1 tablespoon finely grated shallot
• ▢ 2 teaspoons dried Italian seasoning
• ▢ 1 1/2 teaspoons smoked paprika
• ▢ 3/4 teaspoon black pepper
• ▢ 3/4 teaspoon kosher salt
• ▢ 1/4 teaspoon crushed red pepper flakes (optional)

Instructions

Preparation Steps

• Pat the steak dry and trim any silverskin. Lightly score the surface in a shallow crosshatch (about 1/8-inch deep) to help the marinade penetrate. Place the meat in a large zip-top bag or shallow glass dish.
• Whisk together all marinade ingredients until smooth. Set aside 2 tablespoons of the marinade in a small saucepan for finishing; pour the remainder over the steak, seal, and massage to coat, working it into the scores.
• Refrigerate the steak 4–12 hours, turning once or twice. For a stronger flavor, marinate up to 24 hours.
• Remove the steak from the marinade, letting excess drip off; discard used marinade. Pat very dry with paper towels and set on a wire rack. Let it stand at room temperature for 20–30 minutes while you preheat your cooking method.
• To broil: Position an oven rack 6 inches from the broiler and preheat the broiler on high. Set a rimmed sheet pan or broiler pan under the heat for 5 minutes to preheat. Place the steak on the hot pan and broil 5–6 minutes. Flip and broil another 4–6 minutes, until an instant-read thermometer inserted in the thickest part reads 130–135°F for medium-rare (135–140°F for medium).
• To grill: Preheat a gas or charcoal grill to 500°F (hot fire). Clean and oil the grates. Grill the steak 5–7 minutes, covered, then flip and grill 4–6 minutes more, aiming for 130–135°F in the center for medium-rare (135–140°F for medium).
• Transfer the steak to a cutting board and rest 10 minutes, loosely tented with foil. Meanwhile, bring the reserved clean marinade to a lively simmer in the small saucepan for 2–3 minutes to make a quick drizzle.
• Slice the steak thinly against the grain at a 45° angle. Spoon over a little of the reduced marinade, scatter with chopped parsley, and serve immediately.

Notes

Tip: For a superior crust, blot the steak very dry before cooking and preheat your pan or grill thoroughly—moisture and cool surfaces inhibit browning.

Leftovers keep well up to 4 days; slice thin and rewarm gently or serve chilled in sandwiches or salads.
