FAQ

Can I use this marinade on other cuts of beef?

Yes, this garlic-thyme mixture works well on ribeye, strip steak, or flank steak. Adjust cooking times based on thickness and desired doneness.

How long can I marinate the steak?

Marinate for 30 minutes to 4 hours maximum. Longer marinating can break down the meat fibers and affect texture.

What if I don't have a grill?

Use a cast iron skillet or grill pan over medium-high heat. Cook for similar timing, ensuring good ventilation for smoke.
