London Broil substitute

Best substitute

Top round roast or top round steak

Use the same amount by weight as the london broil you are replacing

Best for marinated broiled beef

Close match

The best substitute for London broil is top round roast or top round steak at 1:1, because that is usually what London broil already is. Bottom round or sirloin tip also work at 1:1, and flank steak is the best swap if the recipe is a quick marinate-and-broil. The job this cut does is provide a large, cheap, very lean piece of beef that gets its tenderness from a marinade, a fast high-heat cook and thin slicing across the grain, not from marbling. Match the leanness and the shape and the recipe works.

Substitutes for London Broil with ratios

  1. 2Bottom round or sirloin tip roast

    Close match

    Use the same amount by weight

    Neighbouring cuts from the same rear leg, similarly lean and similarly priced.

    What changes
    Best for
    marinated broiled beef, roast beef, sandwich beef, budget cooking

    Very close, with a slightly firmer and marginally chewier bite than top round because the muscle fibres are a little coarser. Nobody eating thin slices with a marinade on them will pick the difference. Bottom round in particular benefits from a longer marinade, eight hours rather than four, and it punishes overcooking harder, so pull it at 130 F.

  2. 3Flank steak

    Different texture

    Use the same amount by weight

    The other cut that gets sold as London broil, especially in older recipes and East Coast markets.

    What changes
    Best for
    quick weeknight marinate and broil, steak salad, fajitas, sliced steak sandwiches

    Much thinner than a round-based London broil, so it broils in six to ten minutes total instead of twenty, and it tastes a touch richer and more distinctly beefy. Its coarse grain means thin cross-grain slicing is mandatory. If your recipe gives a long broiling time, ignore it and watch the meat. This is the better choice when you want dinner in half an hour.

  3. 4Sirloin steak or top sirloin

    Close match

    Use the same amount by weight

    A step up in tenderness for a modest step up in price, and available everywhere.

    What changes
    Best for
    marinated broiled beef, steak served in slices, cooks who want a more tender result

    Noticeably more tender and juicier than round, with a slightly richer flavor, so the dish is simply better. The trade-off is that the marinade matters less, meaning the tangy soy, Worcestershire and garlic character many London broil recipes rely on penetrates less deeply into a more marbled cut. Reduce the marinade time and consider spooning some over the sliced meat at the end.

  4. 5Eye of round roast

    Different texture

    Use the same amount by weight

    The leanest and often cheapest roast in the case, and the strictest test of technique.

    What changes
    Best for
    very thin sliced roast beef, cold beef sandwiches, tight budgets

    It has even less marbling than top round, so the margin for error narrows to almost nothing: at medium it is dry and faintly livery, and at medium-rare sliced paper-thin it is genuinely good. Salt it the day before, marinate it, and use a thermometer rather than a timer. Its neat cylindrical shape actually slices more evenly than a top round slab.

  5. 6Chuck roast, braised instead of broiled (different dish, honest option)

    Different texture

    Use the same amount by weight

    Named because chuck is often the only cheap beef left, and because using it as London broil is the classic mistake.

    What changes
    Best for
    pot roast, shredded beef, slow-cooker dinners

    Broiled like London broil, chuck comes out chewy and gristly no matter how long it marinated, because its toughness comes from connective tissue that only melts with hours of moist heat. If chuck is what you have, change the plan: braise it covered at 300 F for three hours and serve it as pot roast. Delicious, but it is not London broil and no marinade will make it so.

What is London Broil?

London Broil is London broil is a store label rather than an anatomical cut: in most American supermarkets it means a thick lean slab of top round, and occasionally flank steak, sold ready for marinating and broiling.

Cooking tips

  • The tenderness of London broil comes from three things and none of them is the cut: an acidic marinade, cooking no further than medium-rare, and slicing very thin across the grain. Get all three right and even eye of round is good; get the slicing wrong and even sirloin is ropey.
  • Marinate lean round-based cuts four to twelve hours, but not much longer. Beyond about a day, acid from vinegar, citrus or wine turns the surface of the meat mushy and grey rather than more tender.
  • Broil on the top rack, three to four inches from the element, and turn once. For a two-inch top round, that is roughly eight to ten minutes a side, but the only reliable guide is an instant-read thermometer reading 130 to 135 F at the thickest point.
  • Rest ten minutes before slicing, then cut at a slight angle across the grain into slices no thicker than a quarter inch. Slicing on the bias makes each slice wider and shortens the muscle fibres further, which reads as more tender in the mouth.
  • Because these cuts are so lean, the pan or broiler pan gives you very little fat to work with. Save the leftover marinade, boil it hard for at least a full minute to make it safe, and use it as a sauce so the plate is not dry.

Frequently asked questions

What cut is London broil actually?

It depends on the shop. Most American supermarkets put the label on a thick piece of top round; some use bottom round or sirloin tip, and traditionally London broil meant flank steak. It is a marketing name for lean beef sold to be marinated and broiled, so ask the counter what is underneath the sticker.

Can I just leave it out?

No, it is the main protein. But because London broil is a label rather than a cut, you have unusual freedom: buy any large lean piece of beef from the round or sirloin, marinate it, broil it to medium-rare and slice it thin. That is the whole recipe.

Is London broil a cooking method or a cut of meat?

Originally a method, and that is the useful way to think about it. London broil means marinating a lean cut, broiling or grilling it fast over high heat and slicing it thin on the bias. Over time American butchers turned the name into a product label, which is why the confusion exists.

Why is my London broil tough?

Almost certainly overcooking or slicing with the grain. Lean round has no marbling to hide behind, so at medium-well it is dry and stringy. Cook to 130 to 135 F, rest it, then look carefully at which way the muscle fibres run and cut across them in thin slices.

Can I use London broil for pot roast, or pot roast beef for London broil?

The first works reasonably, the second does not. Lean round can be braised into a decent if slightly dry pot roast. Chuck and brisket, the usual pot roast cuts, are full of connective tissue and come out chewy when broiled fast, so they are not interchangeable in that direction.
