This one’s bold, juicy, and crazy good — sweet, savory, and perfect for a quick grill night or a show-off dinner.

Ingredients

• 1½–2 lb flat iron steak
• 1 tbsp olive oil
• Girls Gone Grillin’ S.P.G. Plus a Kiss of Onion BBQ seasoning
  
• Optional: garlic powder or steak seasoning
• Balsamic Soy Glaze
• ½ cup balsamic vinegar
• ¼ cup soy sauce (or low sodium)
• 2 tbsp brown sugar or honey
• 2 cloves garlic, minced
• 1 tsp Dijon mustard
• ½ tsp black pepper
• Optional kick: pinch of red pepper flakes

Make the Glaze

Add all glaze ingredients to a small saucepan.

Simmer over medium-low heat 10–15 minutes, stirring often, until reduced and syrupy.

Remove from heat — it will thicken more as it cools.

Grill the Steak

Preheat grill to medium-high (425–450°F).

Pat steak dry, rub with olive oil, and season generously.

Grill 4–5 minutes per side for medium-rare (internal temp ~130–135°F).

During the last minute, brush lightly with glaze (don’t burn it).

Rest & Serve

Rest steak 5–10 minutes, then slice against the grain.

Drizzle with extra balsamic soy glaze right before serving.
