Effortless Elegance: Slow Cooker London Broil Recipes for Delicious Dinners
London broil, often perceived as a tough cut of beef, can transform into a tender, flavorful masterpiece with the magic of a slow cooker. Forget hours of babysitting a grill; this method is all about set-it-and-forget-it convenience, perfect for busy weeknights or relaxed weekends. This blog post will guide you through several delicious slow cooker London broil recipes, complete with detailed instructions, tips, and variations to suit your taste. We’ll cover everything from choosing the right cut to achieving that melt-in-your-mouth texture.
## What is London Broil?
Before diving into the recipes, let’s clarify what we’re working with. London broil isn’t actually a specific cut of beef but rather a method of preparing it. The name refers to broiling (or grilling) a relatively lean cut of beef and then slicing it thinly against the grain. While traditionally top round or flank steak are used, for the slow cooker, we primarily focus on top round due to its ability to become incredibly tender with prolonged, low-temperature cooking.
**Why Choose Slow Cooker London Broil?**
The slow cooker is a game-changer for London broil. Here’s why:
* **Tenderizes Tough Cuts:** The low and slow cooking process breaks down tough muscle fibers, resulting in remarkably tender meat.
* **Enhances Flavor:** The long cooking time allows the meat to absorb the flavors of the marinade or braising liquid, creating a deeply rich and savory dish.
* **Convenience:** Simply prep the ingredients, toss them in the slow cooker, and let it do its thing. Perfect for busy lifestyles!
* **Budget-Friendly:** Top round is generally a more affordable cut of beef, making this a cost-effective way to enjoy a delicious and satisfying meal.
## Choosing the Right Cut of Beef
While “London broil” often implies flank steak, for slow cooking, **top round** is the preferred choice. Look for a top round roast that is at least 1-2 inches thick. Some marbling (flecks of fat within the meat) is desirable, as it contributes to flavor and moisture, but avoid cuts that are overly fatty, as they can become greasy during slow cooking. Ask your butcher for assistance if you’re unsure.
## Essential Slow Cooker Equipment
* **Slow Cooker (Crock-Pot):** A 6-quart or larger slow cooker is recommended.
* **Cutting Board:** For prepping vegetables and slicing the cooked London broil.
* **Sharp Knife:** Essential for trimming excess fat and slicing the meat.
* **Measuring Cups and Spoons:** For accurate ingredient measurements.
* **Tongs:** For handling the hot meat and vegetables.
* **Meat Thermometer (Optional):** To ensure the meat is cooked to a safe internal temperature.
## Recipe 1: Classic Slow Cooker London Broil
This recipe is a simple and flavorful starting point. It utilizes a basic marinade and slow cooking to create a tender and delicious London broil.
**Ingredients:**
* 2-3 lb Top Round Roast (London Broil)
* 1 large Onion, sliced
* 2 cloves Garlic, minced
* 1/4 cup Soy Sauce
* 1/4 cup Worcestershire Sauce
* 2 tablespoons Olive Oil
* 1 tablespoon Dijon Mustard
* 1 teaspoon Dried Thyme
* 1/2 teaspoon Black Pepper
* 1/2 cup Beef Broth
**Instructions:**
1. **Prepare the Marinade:** In a bowl, whisk together soy sauce, Worcestershire sauce, olive oil, Dijon mustard, minced garlic, dried thyme, and black pepper.
2. **Marinate the Beef:** Place the top round roast in a large resealable plastic bag or a shallow dish. Pour the marinade over the beef, ensuring it’s evenly coated. Seal the bag or cover the dish and refrigerate for at least 4 hours, or preferably overnight. The longer it marinates, the more flavorful and tender the beef will be.
3. **Sear the Beef (Optional but Recommended):** While not strictly necessary, searing the beef before slow cooking adds a rich, caramelized flavor and helps to seal in the juices. Heat a large skillet over medium-high heat. Remove the beef from the marinade (reserve the marinade) and pat it dry with paper towels. Sear the beef on all sides for 2-3 minutes per side, until nicely browned.
4. **Assemble the Slow Cooker:** Place the sliced onions in the bottom of the slow cooker. This will create a bed for the beef and prevent it from sticking. Place the seared (or unseared) beef roast on top of the onions.
5. **Add Liquids:** Pour the reserved marinade and beef broth over the beef.
6. **Slow Cook:** Cover the slow cooker and cook on low for 6-8 hours, or on high for 3-4 hours, or until the beef is fork-tender. Cooking times may vary depending on your slow cooker, so check for doneness after 6 hours on low or 3 hours on high. The internal temperature of the beef should reach at least 145°F (63°C) for medium-rare, 160°F (71°C) for medium, or 170°F (77°C) for well-done. Use a meat thermometer to check the internal temperature.
7. **Rest and Slice:** Once the beef is cooked through, remove it from the slow cooker and let it rest for at least 10-15 minutes before slicing. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful result.
8. **Slice Against the Grain:** Use a sharp knife to slice the London broil thinly against the grain. This is crucial for maximizing tenderness. The grain refers to the direction of the muscle fibers. Look closely at the meat and slice perpendicular to the direction of the fibers.
9. **Serve:** Serve the sliced London broil with the cooking liquid from the slow cooker, mashed potatoes, roasted vegetables, or your favorite sides.

7. **Make the Balsamic Glaze (Optional):** While the beef is resting, prepare the balsamic glaze. In a small saucepan, combine balsamic vinegar and honey or maple syrup (if using). Bring to a simmer over medium heat and cook for 5-7 minutes, or until the glaze has thickened slightly. Be careful not to burn it.
8. **Rest and Slice:** Remove the beef from the slow cooker and let it rest for 10-15 minutes before slicing.

## Tips for Perfect Slow Cooker London Broil
* **Don’t Overcook:** Overcooked London broil, even in a slow cooker, can become dry and tough. Check for doneness regularly after 6 hours on low or 3 hours on high.
* **Sear for Flavor:** Searing the beef before slow cooking adds a significant boost of flavor. Don’t skip this step if you have the time.
* **Marinate for Tenderness:** Marinating the beef helps to tenderize it and infuse it with flavor. Aim for at least 4 hours of marinating time, or preferably overnight.
* **Slice Against the Grain:** This is the most important step for ensuring tenderness. Always slice the London broil thinly against the grain.
* **Rest the Meat:** Letting the beef rest after cooking allows the juices to redistribute, resulting in a more tender and flavorful result. Don’t skip this step!
* **Thicken the Sauce (If Desired):** If you want a thicker sauce, you can whisk together 1-2 tablespoons of cornstarch with an equal amount of cold water and stir it into the slow cooker during the last 30 minutes of cooking. Alternatively, you can transfer the cooking liquid to a saucepan and simmer it over medium heat until it thickens.
* **Add Vegetables:** Feel free to add other vegetables to the slow cooker along with the onions, such as carrots, potatoes, or celery. Add root vegetables at the beginning of the cooking time, and more delicate vegetables (like broccoli or bell peppers) during the last hour of cooking.
* **Adjust Seasoning:** Taste the cooking liquid and adjust the seasoning as needed before serving. You may need to add more salt, pepper, or other spices to achieve the desired flavor.
* **Use a Meat Thermometer:** To ensure your London broil is cooked to the correct internal temperature, use a meat thermometer. Insert the thermometer into the thickest part of the meat, avoiding bone.
* **Don’t overcrowd the slow cooker:** If you’re making a large batch, it’s best to cook in batches to ensure even cooking.
