Ingredients for Keto-Friendly Broiled Flank Steak

• 1.5 to 2 pounds flank steak (look for a well-marbled cut for maximum tenderness)
• 1/4 cup olive oil (or avocado oil for a keto-friendly fat option)
• 3 tablespoons soy sauce (or coconut aminos for a gluten-free alternative)
• 2 tablespoons apple cider vinegar (adds a tangy kick to the marinade)
• 2 cloves garlic, minced (for a robust, savory flavor)
• 1 teaspoon smoked paprika (adds a hint of smokiness)
• 1 teaspoon onion powder (enhances the marinade’s depth of flavor)
• 1/2 teaspoon black pepper (freshly ground for the best taste)
• 1/2 teaspoon sea salt (adjust to taste)
• 1/2 teaspoon red pepper flakes (optional, for a touch of heat)
• 1 tablespoon fresh rosemary, chopped (or 1 teaspoon dried rosemary for herbaceous notes)
• 1 tablespoon fresh thyme, chopped (or 1 teaspoon dried thyme for added aroma)

Step-by-Step Directions for Keto-Friendly Broiled Flank Steak

Step 1: Prepare the Marinade

1. In a medium-sized bowl, whisk together 1/4 cup olive oil, 3 tablespoons soy sauce, 2 tablespoons apple cider vinegar, 2 minced garlic cloves, 1 teaspoon smoked paprika, 1 teaspoon onion powder, 1/2 teaspoon black pepper, 1/2 teaspoon sea salt, 1/2 teaspoon red pepper flakes (optional), 1 tablespoon fresh rosemary, and 1 tablespoon fresh thyme.
2. Place the 1.5 to 2 pounds flank steak in a large resealable plastic bag or shallow dish. Pour the marinade over the steak, ensuring it’s fully coated. Seal the bag or cover the dish, then refrigerate for at least 1 hour (or up to 4 hours for deeper flavor).

Step 2: Preheat the Broiler

1. While the steak marinates, preheat your broiler to high. Adjust the oven rack to the top position, about 4-6 inches from the broiler element.
2. Line a broiler pan or baking sheet with foil for easy cleanup. Place a wire rack on top to allow air circulation and even cooking.

Step 3: Prepare the Steak for Broiling

1. Remove the steak from the marinade, letting any excess drip off. Discard the remaining marinade.
2. Pat the steak dry with paper towels to ensure a good sear. Place it on the prepared wire rack.

Step 4: Broil the Steak

1. Broil the flank steak for 5-6 minutes per side for medium-rare, or until the internal temperature reaches 130°F (54°C) on a meat ther).mometer. For medium, cook until the thermometer reads 140°F (60°C
2. Keep a close eye on the steak to prevent burning, as broiling can cook food quickly.

Step 5: Rest and Slice the Steak

1. Once cooked, transfer the steak to a cutting board and let it rest for 10 minutes. This allows the juices to redistribute, ensuring a moist and tender result.
2. After resting, cut the steak against the grain into thin slices. This step is crucial for achieving the most tender texture.

Step 6: Serve and Enjoy

1. Serve your Keto-Friendly Broiled Flank Steak with your favorite low-carb sides, such as roasted vegetables, cauliflower mash, or a fresh green salad.

Storage Instructions

To store your Keto-Friendly Broiled Flank Steak, let it cool completely to room temperature before transferring it to an airtight container or wrapping it tightly in plastic wrap. Refrigerate for up to 3-4 days to maintain freshness. For best results, slice the steak only when ready to serve, as this helps retain its moisture. When reheating, place the steak in a preheated oven at 300°F (150°C) for about 10 minutes, or until warmed through. Avoid using the microwave, as it can dry out the meat. If you’d like to enjoy it cold, thinly sliced steak makes a delicious addition to salads or keto-friendly wraps. Always use a clean knife and cutting board to prevent cross-contamination.

Tips for Achieving Maximum Flavor

To elevate the taste of your Keto-Friendly Broiled Flank Steak, start by marinating the steak for at least 1-4 hours—this allows the flavors to penetrate deeply. Use fresh herbs like rosemary and thyme for a vibrant, aromatic touch, and don’t shy away from bold seasonings like smoked paprika and garlic. When broiling, ensure your oven rack is positioned close to the heat source for a perfectly caramelized crust. Always let the steak rest for 10 minutes after cooking to lock in juices, and slice it against the grain for maximum tenderness. For an extra flavor boost, drizzle the sliced steak with a bit of olive oil or a squeeze of lemon before serving. These simple steps will ensure a restaurant-quality meal every time!
