Preparation and Cooking
Preparing the London Broil Recipe with Onions
This step is where the magic begins. Prepping your London broil properly makes all the difference between a tough piece of meat and a melt-in-your-mouth masterpiece. Don’t skip these steps!
1. Choose the Right Cut of Meat
London broil typically uses flank steak or top round. Both are lean and flavorful but can be tough if not prepared correctly. Look for a cut that’s about 1½ to 2 inches thick with good marbling—just a little fat running through it for flavor.
2. Tenderize the Beef
Tenderizing is key to breaking down the muscle fibers and making your steak soft and juicy. Here’s how to do it:
- Use a meat mallet: Gently pound the meat to flatten it slightly, focusing on the thicker areas.
- Score the surface: Lightly slice diagonal cuts across the top in a crisscross pattern—this helps the marinade penetrate deeper.
3. Marinate Like a Pro
A great marinade not only flavors the meat but also helps tenderize it. Combine these ingredients in a bowl:
- ¼ cup Worcestershire sauce
- 3 tbsp soy sauce
- 2 tbsp olive oil
- 3 cloves garlic, minced
- 1 tsp black pepper
- Optional: 2 tbsp balsamic vinegar or red wine for extra depth
Place the beef in a resealable bag or shallow dish and pour the marinade over it. Make sure it’s fully coated, then seal it up. Pop it in the fridge for at least 4 hours, but overnight is even better.
Preparing the Onions
While your beef marinates, let’s get those onions ready. this caramelization guide are the secret weapon of this dish—sweet, savory, and totally irresistible.
1. Choosing the Right Onions
Yellow onions work best for caramelizing because they’re naturally sweet. If you want a slightly sharper flavor, go for white onions
2. Slice Them Up
Peel the onions and cut them into thin, even slices. (Pro tip: Use a sharp knife to avoid crushing the onions, which can release too much water.
3. Pre-Cooking Prep
Before cooking, sprinkle a pinch of salt over your onion slices. This draws out moisture and helps them cook evenly.
Cooking Process
Now it’s time to bring it all together—get ready to sear, caramelize, and combine for the ultimate flavor explosion!
1. Searing the London Broil
Searing locks in the juices and creates that crave-worthy crust on the outside of the beef.
- Heat a cast iron skillet or grill pan over medium-high heat.
- Add a tablespoon of oil and let it shimmer.
- Place the beef in the pan and sear for about 3-4 minutes per side until it develops a golden-brown crust.
2. Caramelizing the Onions
Use the same skillet to cook your onions. (No need to clean it—you want those beefy bits!)
- Add a little more oil or a pat of butter to the pan.
- Toss in your sliced onions and cook on low heat.
- Stir occasionally, letting them turn golden brown and soft. This can take 15-20 minutes. If they stick, splash in a little beef broth or water.
3. Combining the Flavors
Once your onions are caramelized, remove them from the skillet and set them aside. Place the seared beef back into the pan, layering the onions on top.
4. Slow Cooking for Tenderness
There are two ways to finish the dish:
- Oven Method: Preheat to 375°F. Cover the skillet with foil and bake for 20-30 minutes until the beef reaches your desired doneness.
- Slow Cooker Method: Transfer the beef and onions to a slow cooker, set it on low, and cook for 3-4 hours.
5. Checking Doneness
Use a meat thermometer to ensure your London broil is cooked perfectly:
- Medium-rare: 130°F
- Medium: 140°F
- Medium-well: 150°F
Let the meat rest for 10 minutes before slicing.
Serving and Pairing for tender London broil recipe with onions
Finishing Touches
The hard part is over! Now it’s all about letting the flavors shine and plating your dish like a pro. Here’s how to wrap it up.
1. Rest the Meat
After cooking, let your London broil rest for 10 minutes. This allows the juices to redistribute, making every slice tender and juicy.
2. Slice Against the Grain
Grab a sharp knife and cut the beef into thin slices at a slight angle, against the grain. (What’s the grain? Those long muscle fibers running through the meat.) Slicing this way keeps the meat tender and easy to chew.
3. Plate with Style
Arrange the slices of beef on a large serving platter. Spoon the caramelized onions over the top, letting them tumble naturally. Add a sprinkle of fresh parsley or thyme for a pop of color. For an extra touch, drizzle any leftover pan juices or a splash of balsamic reduction over the top.
Sauce and Garnishes
Elevate your London broil with a simple sauce or garnish that ties the dish together. Here are a few ideas:
1. Easy Pan Sauce
After removing the beef and onions, deglaze your skillet:
- Add ½ cup beef broth and a splash of red wine or balsamic vinegar.
- Scrape up any browned bits, then simmer until the liquid reduces and thickens.
Pour the sauce over the beef for a savory finish.
2. Garnish Ideas
- Fresh Herbs: Chopped parsley, thyme, or rosemary.
- Citrus Zest: A sprinkle of lemon or orange zest adds brightness.
- Cracked Black Pepper: For a rustic touch.
3. Cheese Option
Feeling indulgent? Add a sprinkle of crumbled blue cheese or shaved Parmesan over the caramelized onions.

A great London broil needs equally delicious sides to complete the meal. Here are some classic pairings that will take your dish to the next level:
