What Is London Broil And How To Choose The Right Cut

London broil refers to a cooking method rather than a specific cut of meat. The term typically describes flank steak or top round steak, cut against the grain into thin slices. Butchers label these cuts as “London Broil” due to their suitability for this preparation style.

Top round steak stands out as the most common cut for London broil, coming from the rear leg of the cow. This lean cut features minimal marbling with a distinctive grain pattern running through the meat.

Here’s what to look for when selecting London broil cuts:

• Choose meat with bright red coloring without brown spots
• Look for pieces 1.5 to 2 inches thick for optimal cooking
• Select cuts with minimal visible fat around the edges
• Verify uniform thickness throughout the piece
• Check for a clear grain pattern running in one direction

The ideal weight for a London broil cut ranges between 2 to 3 pounds. This size provides enough servings for 4 to 6 people while ensuring even cooking in a slow cooker.

These cuts contain high protein content with lean muscle fibers, making them perfect for slow cooking methods that break down tough connective tissues. The extended cooking process transforms these budget-friendly cuts into tender, flavorful meals.

Essential Ingredients For Slow Cooker London Broil

A successful slow cooker London broil requires specific ingredients to create a tender, flavorful result. The combination of marinades, seasonings, vegetables, and additional components transforms this lean cut into a memorable meal.

Marinades And Seasonings

The base marinade combines 1/2 cup soy sauce, 1/4 cup Worcestershire sauce, 3 minced garlic cloves, 2 tablespoons olive oil, and 1 tablespoon dried Italian herbs. Additional seasoning options include:

• Black pepper, kosher salt, and onion powder for creating a savory crust
• Red wine vinegar or balsamic vinegar to tenderize the meat
• Fresh herbs like rosemary, thyme, or oregano for aromatic depth
• Dijon mustard or brown sugar to balance flavors
• Beef broth or stock to create a rich cooking liquid

Vegetables And Add-ins

The slow cooker environment creates an ideal setting for vegetables to absorb meat flavors. Essential vegetable additions include:

• Yellow onions, sliced into rings for a sweet undertone
• Baby carrots or carrot chunks for natural sweetness
• Quartered potatoes (red or Yukon gold) for heartiness
• Mushrooms (button or cremini) for umami flavor
• Celery stalks cut into 2-inch pieces for aromatics

• Cornstarch for thickening the gravy
• Bay leaves for depth
• Pearl onions for texture contrast
• Minced shallots for subtle onion flavor
• Beef bouillon cubes for intensified flavor

Perfect Slow Cooker Settings And Time

Optimal slow cooker settings transform London broil into tender, juicy meat through controlled temperature and precise timing. The cooking environment creates the ideal conditions for breaking down tough muscle fibers.

Temperature Guidelines

The optimal slow cooker temperature for London broil is LOW (200°F) for tender results. High settings (300°F) cook the meat faster but produce less tender results. A digital thermometer confirms doneness at 145°F for medium-rare or 160°F for medium. The internal temperature continues rising 5-10 degrees during the resting period.

Cooking Duration Tips

London broil requires 8-10 hours on LOW for maximum tenderness. A 2-3 pound cut takes 6-8 hours to reach medium-rare on LOW. The HIGH setting reduces cooking time to 4-5 hours but sacrifices texture quality. Adding vegetables extends cooking time by 30-45 minutes. Dense root vegetables like carrots potatoes go at the bottom of the pot. The meat sits on top of the vegetable layer for even heat distribution.

Best Ways To Serve Slow Cooked London Broil

Slow cooked London broil transforms into a tender masterpiece ready for elegant presentation. The serving process requires attention to detail in both slicing technique and accompaniment selection.

Slicing And Presentation

London broil slicing demands a precise 45-degree angle cut against the grain to maximize tenderness. A sharp carving knife creates clean, thin slices approximately 1/4-inch thick across the meat’s surface. Rest the meat for 10 minutes before cutting to retain its juices. Place the slices in an overlapping arrangement on a warmed platter, drizzling them with the collected cooking juices. Garnish with fresh herbs like parsley or thyme for visual appeal. For family-style service, arrange the meat in a fan pattern surrounded by the cooked vegetables from the slow cooker.

Side Dish Pairings

Classic potato pairings include creamy mashed potatoes, roasted fingerlings or sweet potato wedges. Green vegetables complement the rich meat perfectly: steamed asparagus, roasted Brussels sprouts or sautéed green beans add color contrast. Rice variations enhance the meal: wild rice pilaf, brown rice or rice medley absorb the flavorful cooking juices. Fresh salad options include arugula with shaved parmesan, mixed greens with balsamic vinaigrette or a crisp Caesar salad. Crusty bread selections serve as excellent vehicles for the savory sauce: French baguette, sourdough or garlic bread complete the dining experience.
