Substitutions & Dietary Swaps

• Gluten-free: Use tamari instead of soy sauce.
• Low-sodium: Replace broth with low-sodium broth and reduce soy sauce by half.
• Garlic-free: Substitute 1/2 tsp garlic powder.
• Beef alternatives: Flank steak or bottom round roast also work.

Chef’s Pro Tips

• Sear for depth: Browning maximizes richness.
• Cook low and slow: The cut becomes tender only with long, gentle heat.
• Let it rest: Rest 10 minutes before slicing.
• Slice correctly: Always cut against the grain to avoid chewiness.

Make Ahead, Storage & Reheating

Slow Cooker London Broil reheats beautifully. Store leftovers in an airtight container for up to 4 days or freeze for 3 months.

• Make ahead: Prep ingredients in a freezer bag; thaw overnight.
• Reheat: Warm gently in a saucepan with a splash of broth.
• Freeze: Slice before freezing for easier portioning.

Troubleshooting & Common Mistakes

• Beef is tough: It likely needs more time; cook at least 6 hours on LOW.
• Too salty: Use low-sodium broth and reduce soy sauce next time.
• Dry texture: Ensure enough broth; do not cook on HIGH.
• Watery sauce: Thicken with a cornstarch slurry.

Flavor Pairings & Serving Suggestions

Slow Cooker London Broil pairs beautifully with buttery mashed potatoes, roasted vegetables, or a crusty artisan bread to soak up the gravy.
