Step‑by‑Step Instructions for Crockpot London Broil Au Jus
Step 1: Prep the Roast
Begin by generously seasoning your 2 pounds of London broil with salt and pepper. Make sure to cover all sides to enhance the flavor. This step is crucial as it forms the foundation for your Crockpot London Broil Au Jus. Allow the meat to sit for a few minutes, allowing the seasoning to penetrate.
Step 2: Add Flavors
Next, create small slits in the roast using a sharp knife and insert slices of fresh garlic into each slit. This technique infuses the meat with aromatic flavor as it slow-cooks. The garlic will mellow under the low heat but will still impart a delightful taste to the final dish.
Step 3: Layer the Crock Pot
In your crock pot, start by placing half of the sliced onion at the bottom. Then, carefully position the seasoned London broil on top, followed by the remaining onion slices. To create a savory cooking liquid for your London broil, pour in ¾ cup of water alongside 3 tablespoons of soy sauce or tamari over the meat.
Step 4: Slow Cook
Cover your crock pot with the lid and set it to cook on low for 8 to 10 hours. The goal is to let the meat slowly become fork-tender while absorbing all the flavors of the au jus. You’ll know it’s ready when the meat is easily shredded and emits a mouthwatering aroma that fills your kitchen.
Step 5: Rest & Serve
Once cooked, carefully remove the London broil from the crock pot and let it rest for about 10-15 minutes. This allows the juices to redistribute, making for a succulent meal. For serving, slice the meat against the grain and drizzle with au jus, or serve it on the side for dipping.
Step 6: Make Gravy (optional)
If you desire a richer experience, you can make a gravy using the drippings. In a small bowl, mix 2 tablespoons of cornstarch with 2 tablespoons of cold water until smooth. Heat the remaining drippings in a saucepan, whisk in the cornstarch mixture, and stir over medium heat until thickened. This adds an extra layer of delight to your Crockpot London Broil Au Jus.

Expert Tips for Crockpot London Broil Au Jus
• Check Internal Temperature: Use a meat thermometer to ensure the roast reaches 120°F for perfect tenderness. Avoid overcooking, as it can lead to shredding.
• Adjust Cooking Time: Different crock pots may vary; if yours runs hot or cold, monitor the cooking times and adjust accordingly for the best results.
• Slice with Care: A sharp knife is essential for slicing against the grain; this keeps the meat juicy and tender, enhancing your Crockpot London Broil Au Jus experience.
• Make Gravy Smooth: For a clump-free gravy, ensure your cornstarch mixture is completely smooth before adding it to drippings; whisking continuously helps achieve the perfect texture.
• Season Wisely: Don’t be shy with seasonings! Adjust salt and pepper to your taste, and consider adding herbs to enhance the flavor of your au jus.

Crockpot London Broil Au Jus Recipe FAQs
What should I look for when selecting a London broil?
Absolutely! When choosing a London broil, look for a cut that is bright red with minimal marbling. The meat should feel firm and be free from any dark spots or discoloration, indicating freshness. If possible, opt for grass-fed beef for enhanced flavor and tenderness.
How should I store leftovers from this recipe?
Leftovers from your Crockpot London Broil Au Jus can be stored in an airtight container in the fridge for up to 4 days. I always recommend keeping the meat unsliced, as this helps to retain moisture and flavor. If you have larger quantities, consider placing a paper towel in the container to absorb any excess moisture, ensuring your leftovers stay delicious.
Can I freeze the London broil?
Yes, definitely! You can freeze your sliced or unsliced Crockpot London Broil Au Jus for up to 3 months. Just make sure to use a freezer-safe bag and remove as much air as possible to avoid freezer burn. For best results, wrap the meat in plastic wrap first, then place it in the bag. When you’re ready to enjoy it, thaw it in the refrigerator overnight for gentle defrosting.
What if my London broil is tough after cooking?
Very often, a tough London broil indicates it hasn’t cooked long enough or wasn’t kept at a low enough temperature. If you encounter this, try returning the meat to the crock pot for an additional hour or two on low, alongside a dash more liquid. If you find that your timing is off, using a meat thermometer can help you monitor doneness—aim for an internal temperature of around 120°F for perfectly tender slices.
Is this recipe suitable for gluten-sensitive individuals?
Yes, indeed! To make your Crockpot London Broil Au Jus gluten-free, simply substitute regular soy sauce with gluten-free tamari. This gives you the same rich umami flavor without worrying about gluten. If you have soy allergies, consider using coconut aminos as a tasty alternative, which brings a different flavor profile to the dish while remaining safe for gluten-sensitive diets.
