London Broil vs Roast Beef: Clearing Up the Confusion

Walk into any supermarket meat section or local butcher shop and you’ll likely see both “London broil” and “roast beef” on display. But what’s the real difference between these two popular beef dishes? Are they just interchangeable names for the same cut of meat?

The relationship between London broil and roast beef often causes confusion among home cooks. While they share similarities, important distinctions exist in how they are prepared, served, and enjoyed.

In this comprehensive guide, we’ll break down the key characteristics that set London broil and roast beef apart. Whether you’re an occasional dabbler or aspiring home chef, understanding these nuances can level up your culinary skills and beef menu offerings. Let’s dive in!

London Broil’s Unique Identity

Despite its geographically misleading moniker, London broil is a preparation method developed in America, not England. It involves marinating a flank or top round steak, then broiling or grilling it whole before thinly slicing against the grain.

The keys to great London broil include:

• Marinating – A marinade of oil, acid, and spices tenderizes and infuses flavor.

• Cooking Method – High, dry heat from broiling or grilling.

• Slicing – Thin, against-the-grain slices ensure tenderness.

• Lean Cut – Flank or top round steak provides optimum texture.

So while the term “London broil” has come to represent a specific dish, it originally referred to this unique cooking technique resulting in flavorful, tender meat from typically tough cuts.

The Essence of Roast Beef

In contrast to London broil’s specificity, “roast beef” has a broader meaning. At its core, it refers to oven roasting beef cuts to succulent, fork-tender perfection.

Characteristics of traditional roast beef include:

• Dry Heat – Roasted uncovered in the oven

• Low and Slow – Cooked for hours at ~250°F

• Basting – Frequently basted to enhance flavor and moisture.

• Resting – Allowed to rest before carving and serving.

• Diverse Cuts – Ribs, loin, sirloin, rump, etc.

So roast beef describes both a cooking method and a beloved dish open to interpretation based on cut, seasoning, and doneness preferences.

Key Differences Between the Dishes

With the background covered, where exactly does London broil diverge from a typical roast beef? Here are the top distinguishing factors:

Preferred Cuts

• London Broil – Flank or top round steaks. Their leanness suits the high-heat method.

• Roast Beef – Rib, loin, sirloin, rump, etc. More variety including fattier cuts.

Seasoning Approach

• London Broil – Marinated for hours in oil, acid, and spices.

• Roast Beef – Light coating of herbs, salt, and pepper. Favors beef’s natural flavor.

Cooking Method

• Roast Beef – Low and slow roasting in the oven for tender, even cooking.

Serving Style

Flavor Profile

Fat Content

Are They Completely Different?

While distinct in many regards, London broil and roast beef do share some common ground that blurs the lines between them:

• Both rely on dry heat without moisture braising.

• When sliced thinly, they produce similar textures.

• Top round can be used for both dishes.

• Either can be served au jus or with horseradish sauce.
