Chef’s pro tip

Here is a great tip to get tender London Broil: don’t skip the ‘resting’ phase. Resist the temptation to dive right in after pan-searing. Let the steak rest for about 5 minutes.

What to serve with London broil?

Here are some delicious side dishes that pair perfectly with the London broil.

  • Chimichurri sauce: A refreshing Keto Chimichurri Sauce is a great option to enhance the beef flavors.
  • Creamy cauliflower mash: This low-carb alternative to traditional mashed potatoes pairs well with the richness of the steak.
  • Grilled asparagus: The bitterness of asparagus provides a refreshing contrast.
  • Roasted Brussels sprouts: Brussels Sprouts pair nicely with this tasty beef.
  • Zucchini noodles (Zoodles): Zoodles offer a light, refreshing counterpoint.
  • Avocado salad: Avocado’s natural creaminess pairs well with the steak. Make an avocado green salad to complement your dish.

How to make it healthier?

  • Swap out soy sauce: Soy sauce is high in sodium. So use coconut aminos or liquid aminos to lower the sodium content.
  • Add more veggies: While beef is the star, don’t forget the power of vegetables. Serve the steak with leafy greens or roasted green beans.

Time-saving tips

  • Use a blender: Use a blender to make the London broil marinade. Pulse the garlic cloves, onions, soy sauce, and olive oil in the blender for 10 seconds. You can also use a food processor or immersion blender.
  • Use a meat mallet: Gently pound the surface of the steak with a meat pounder. It makes the steak more tender and speeds up the cooking process.

What can I prepare ahead of time?

  • Marinaded steak: Marinate the meat with London broil seasoning. Store it in a sealable plastic bag in the refrigerator. This will save you time and allow it to absorb the flavors.

Storage and reheating instructions

Storage tips

To store the leftover steak, let it cool down to room temperature. Then wrap it tightly in plastic wrap or transfer it to an airtight container.

  • Refrigerator: Store it in the fridge for 3-4 days.
  • Freezer: Place the leftovers in a freezer-safe bag. It will keep for 2-3 months.

Reheating tips

You can easily reheat the leftovers. In case they are frozen, thaw them in the refrigerator overnight. Then follow the practices below:

  • Oven: Preheat your oven to 350°F (175°C). Place the leftover steak on a baking sheet and cover it with an aluminum foil. Heat it for 10-15 minutes or until it reaches your desired temperature.
  • Stovetop: Heat a small amount of oil in a cast-iron skillet over medium-high heat. Add the leftovers to the hot skillet and cook for 1-2 minutes per side or until heated.

Frequently asked questions

Absolutely! The longer you marinate the London broil cut, the more flavorful it will be. Just don’t do it over 24 hours.

Definitely! The cooking times should be similar to pan grilling but always use a meat thermometer to check the doneness.

Score the surface lightly with a sharp knife on each side.

Ensure the pan is well-heated before adding the meat. A hot pan quickly sears the outside of the steak, creating a crust that prevents sticking.

For kids, cut the tender steak into smaller pieces before serving. You can also make a fun dipping sauce on the side — like a mild salsa or a creamy avocado dip.
