The Story Behind the Keto London Broil

The London Broil is traditionally known for its marinating and broiling technique, which turns a less expensive cut of beef into a mouth-watering meal. Our keto version takes this concept and tailors it to fit a ketogenic dietary pattern, focusing on low-carb, high-fat ingredients that help you maintain ketosis. The inspiration for this dish comes from a desire to enjoy classic flavors while adhering to a health-conscious lifestyle.

Each ingredient has been carefully selected to enhance the natural flavors of the beef while keeping carbs to a minimum. The use of olive oil not only adds healthy fats but also carries the flavors of garlic, rosemary, and spices deep into the meat. The Worcestershire sauce, while modest in quantity, imparts a complex umami taste without adding significant carbs. These key ingredients ensure that every serving of our Keto London Broil is not just a treat for your taste buds but also a fitting component of your keto diet.

What makes this recipe particularly special is the balance it strikes between simplicity and sophistication. The marinade, with its aromatic herbs and spices, doesn’t just tenderize the meat; it creates a crust that’s packed with flavor as it sears to perfection. This dish showcases how a ketogenic diet can be both delicious and diverse, proving that you can enjoy classic dishes with a low-carb twist.

Mastering the Keto London Broil: Tips and Techniques

Creating the perfect Keto London Broil is all about the details. Here’s how you can elevate your cooking game and ensure that your steak is cooked to tender perfection.

Marinating is the first and one of the most crucial steps. It’s essential to allow the meat to marinate for at least 2 hours, but if you can plan ahead, letting it sit overnight will result in a more tender and flavorful steak. The acids in the marinade work to break down the proteins, making the meat more succulent.

When it’s time to cook, make sure your grill or broiler is preheated to high heat. This is key for achieving that desirable sear that locks in juices. If you’re using a meat thermometer, aim for an internal temperature of 135°F for medium-rare—but remember, the temperature will continue to rise slightly as the meat rests after cooking.

Speaking of resting, this is a step you don’t want to skip. Resting the meat for 10 minutes allows the juices to redistribute, resulting in a juicier, more flavorful steak. And when you’re ready to slice, always cut against the grain. This shortens the muscle fibers, making each piece more tender. By following these tips, you’ll take your Keto London Broil from good to great.

Keto London Broil Variations

Herb-Infused Keto London Broil

For those who love a fresh, herbaceous flavor, consider adding a variety of fresh herbs to the marinade. Thyme, oregano, and basil can all contribute to a more nuanced and vibrant taste profile. The key is to finely chop these herbs so they can fully release their flavors into the oil and coat the meat evenly.

Spicy Keto London Broil

If you’re a fan of heat, don’t hesitate to kick things up a notch. Increase the cayenne pepper or add some diced jalapeños to the marinade. The capsaicin in the peppers not only adds spice but also has metabolism-boosting properties, making it a win-win for those on keto.

Citrusy Keto London Broil

Adding a touch of citrus can brighten up the dish and offer a tangy contrast to the rich flavors of the meat. Try incorporating some lemon zest or a squeeze of fresh lime juice into the marinade for a zesty twist.

Ingredient Substitutions for Keto London Broil

While the original recipe is designed to be keto-friendly, there are always options to tweak it based on your preferences or availability of ingredients.

For the olive oil, you can substitute with avocado oil, which has a similar profile of healthy fats and a high smoke point, making it ideal for grilling. If Worcestershire sauce is not your cup of tea or hard to find, consider using coconut aminos. It offers a similar umami flavor with lower carbs and is soy-free. Lastly, if you’re out of fresh rosemary, dried rosemary can be used in a pinch—just remember to use less as the flavor is more concentrated.

Frequently Asked Questions

Here are some common questions and answers to help you make the best Keto London Broil.

Q: Can I use a different cut of beef for this recipe?
A: Absolutely! While London Broil typically refers to a top round roast, you can use flank steak or sirloin tip as alternatives. Just adjust cooking times accordingly.

Q: How can I tell if the steak is done without a meat thermometer?
A: Use the finger test. Press the steak with your finger—the firmer it feels, the more done it is. However, a meat thermometer is the most accurate method.

Q: Is marinating necessary?
A: While you can cook the steak without marinating, doing so adds flavor and tenderness. Even a short marinating time can make a difference.

Q: Can I make this dish ahead of time?
A: Yes, you can marinate the meat and keep it in the fridge up to 24 hours before cooking. Cooked steak can also be stored and reheated, though it’s best enjoyed fresh.

Q: What sides go well with Keto London Broil?
A: Opt for keto-friendly sides like cauliflower mash, roasted Brussels sprouts, or a fresh green salad.

  • Grill or broiler
  • Cutting board
  • Meat thermometer
  • Knife


  • 2 lbs London Broil 907g
  • 3 tbsp olive oil 45ml
  • 2 tbsp Worcestershire sauce 30ml
  • 2 cloves garlic, minced about 1 tsp / 5g
  • 1 tbsp fresh rosemary, finely chopped about 3g
  • 1 tsp sea salt 5g
  • ½ tsp ground black pepper 1g
  • 1 tsp smoked paprika 2g
  • ¼ tsp cayenne pepper optional for heat, 0.5g


  • Begin by preparing the marinade. In a mixing bowl, combine olive oil, Worcestershire sauce, minced garlic, chopped rosemary, sea salt, black pepper, smoked paprika, and cayenne pepper if using. Whisk together until well combined.
  • Place the London Broil in a large, sealable plastic bag or shallow dish. Pour the marinade over the meat, ensuring it's fully coated. Seal the bag or cover the dish, and let the meat marinate in the refrigerator for at least 2 hours, or overnight for best results.
  • Preheat your grill or broiler to high heat. Remove the London Broil from the marinade and let excess drip off. Discard the remaining marinade.
  • Place the London Broil on the grill or under the broiler. For medium-rare, cook for approximately 7-10 minutes on each side, depending on thickness. Use a meat thermometer to ensure an internal temperature of 135°F (57°C) for medium-rare.
  • Once cooked to your desired level of doneness, transfer the London Broil to a cutting board and let it rest for 10 minutes. This allows the juices to redistribute throughout the meat.
  • Slice the meat against the grain into thin strips and serve immediately.


Marinating time can significantly influence the tenderness and flavor of the meat. It's recommended to marinate for at least 2 hours, but overnight will yield the best results.
Always slice the London Broil against the grain to ensure each piece is as tender as possible.
