Ingredients

• 16 ounces Lean boneless beef steak (top sirloin or eye of round is ideal)
• 3 tablespoons Olive oil
• 1 tablespoon Balsamic vinegar
• 1 teaspoon Garlic powder
• 0.5 teaspoon Ground black pepper
• 0.5 teaspoon Salt
• 2 Medium-sized onions
• 0.5 cup Low-sodium chicken broth
• 1 teaspoon Fresh thyme leaves

Directions

Step 1

Begin by preparing the marinade. In a large bowl, combine 2 tablespoons of olive oil, 1 tablespoon balsamic vinegar, 1 teaspoon garlic powder, 0.5 teaspoon ground black pepper, and 0.25 teaspoon salt. Mix well.

Step 2

Place the steak in the bowl, ensuring it is well-coated with the marinade. Cover the bowl and let it marinate in the refrigerator for at least 30 minutes. For optimal flavor, consider marinating the steak for up to 4 hours.

Step 3

While the steak is marinating, peel and slice the onions thinly.

Step 4

In a large non-stick skillet, heat 1 tablespoon of olive oil over medium heat. Add the sliced onions and a pinch of salt. Cook the onions for about 25 minutes, stirring occasionally, until they become golden brown and caramelized. Add the 0.5 cup of low-sodium chicken broth and stir in the 1 teaspoon of fresh thyme leaves, allowing the liquid to reduce and onions to become tender.

Step 5

Preheat a grill or grill pan to medium-high heat.

Step 6

Remove the steak from the marinade and let it sit at room temperature for about 5 minutes.

Step 7

Place the steak on the preheated grill and cook for 4-5 minutes on each side, or until it reaches your desired level of doneness. For a medium-rare steak, aim for an internal temperature of 135°F (57°C).

Step 8

Remove the steak from the grill and let it rest for 5-10 minutes before slicing. This helps the juices redistribute within the meat.

Step 9

Slice the steak thinly against the grain.

Step 10

Serve the grilled steak topped with the sweet caramelized onions and drizzled with any remaining juices from the skillet.
