For the Herb Butter:

1. In a mixing bowl, combine the softened butter with crushed garlic and diced dill.

FAQs

1. Can I use a different type of bread for this sandwich?

Yes! You can use a hoagie roll, ciabatta, or any type of crusty bread you prefer. Just make sure it can hold up to the fillings.

2. Can I use a different cut of steak for this sandwich?

Absolutely! Flank steak, ribeye, or sirloin all work great for steak sandwiches. Just be sure to slice the steak thinly for the best texture.

3. How do I make sure the steak stays tender?

Slicing the steak thinly against the grain will help ensure that the steak stays tender. Also, don’t overcook the steak; it should be just golden, not fully browned.

4. Can I make the herb butter in advance?

Yes, the herb butter can be made ahead of time and stored in the refrigerator for up to 1 week. You can also freeze it for up to 2 months.

5. What if I don’t have a broiler?

If you don’t have a broiler, you can place the sandwich in a preheated oven at 375°F (190°C) for about 5-7 minutes until the cheese is melted.

6. Can I add other vegetables to the sandwich?

Yes! You can add sautéed mushrooms, bell peppers, or even pickled onions for additional flavor.

7. Can I make this sandwich without cheese?

Yes, you can leave out the cheese if you prefer a lighter option or need a dairy-free version.

8. How can I make the steak sandwich spicier?

Add a layer of hot sauce, jalapeños, or chili flakes to spice up the sandwich.

9. Can I freeze the steak sandwiches?

It’s best to freeze the individual components (steak, onions, and bread) separately and assemble the sandwich when you’re ready to eat. You can also freeze the cooked steak and reheat it when needed.

10. How do I get the onions perfectly caramelized?

Make sure to cook the onions over medium-low heat, allowing them to brown slowly. Stir occasionally to prevent burning, and add a pinch of sugar if you like a sweeter caramelization.
