Ingredients

• 1.5 pounds London broil (flank steak or top round)
• 2 tablespoons Olive oil
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 teaspoon Garlic powder
• 0.5 teaspoon Dried rosemary
• 2 tablespoons Butter
• 2 small Shallots, finely chopped
• 2 Garlic cloves, minced
• 8 ounces Cremini mushrooms, sliced
• 1 cup Beef broth
• 0.5 cup Heavy cream
• 1 tablespoon Flour
• 1 tablespoon Fresh parsley, chopped (optional for garnish)

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 2

Rub the London broil with olive oil, then season evenly on both sides with salt, black pepper, garlic powder, and dried rosemary. Let it rest at room temperature for 15 minutes to marinate.

Step 3

Heat a large, oven-safe skillet over medium-high heat. Add a tablespoon of olive oil.

Step 4

Sear the London broil in the hot pan for about 2-3 minutes per side until browned. Transfer the skillet to the preheated oven, and roast for 8-12 minutes or until the internal temperature reaches 130°F (54°C) for medium-rare, or your desired doneness.

Step 5

Remove the steak from the oven, place it on a cutting board, and tent it with aluminum foil. Let it rest for 10 minutes before slicing.

Step 6

While the steak rests, make the mushroom sauce. Return the skillet to the stovetop over medium heat and add the butter.

Step 7

Stir in the shallots and garlic, cooking for 1-2 minutes until fragrant.

Step 8

Add the sliced cremini mushrooms and cook for 5-7 minutes until they release their moisture and are tender.

Step 9

Sprinkle the flour over the mushrooms and stir well, cooking for another 1 minute to remove the raw flour taste.

Step 10

Slowly pour in the beef broth, stirring constantly, and bring the mixture to a simmer. Cook for 2-3 minutes until the sauce thickens slightly.

Step 11

Add the heavy cream, reduce the heat, and let the sauce simmer for 2-3 more minutes. Adjust seasoning with salt and pepper if needed.

Step 12

Slice the London broil thinly against the grain, and serve it on a platter topped with the mushroom sauce.

Step 13

Garnish with fresh parsley, if desired. Serve warm and enjoy!
