For a more intense flavor, marinate the steaks overnight in the refrigerator.
If you prefer a toasted sandwich, lightly grill the baguettes before assembling.
Substitute Swiss cheese with provolone or mozzarella for a different flavor profile.
Can I use a different cut of steak?
Yes, you can use ribeye, strip steak, or even flank steak as alternatives.
How long should I marinate the steak?
For best results, marinate for at least 15 minutes, but overnight marination will enhance the flavor further.
Can I make the garlic aioli ahead of time?
Yes, you can prepare the aioli up to 2 days in advance and store it in the refrigerator.
What can I use instead of Better Than Marinade?
You can use your favorite steak marinade or create a simple mix of olive oil, garlic, soy sauce, and Worcestershire sauce.
How do I know when the steak is cooked to my liking?
Use a meat thermometer: 130°F for medium-rare, 140°F for medium, and 150°F for medium-well.
