Ingredients for Herb Butter Steak Sandwich

To create the perfect Herb Butter Steak Sandwich with Caramelized Onion and Melty Havarti, you’ll need the following ingredients:

  • 1 lb flank steak or sirloin, trimmed
  • 2 tablespoons olive oil
  • Salt and pepper, to taste
  • 1 tablespoon fresh rosemary, chopped
  • 1 tablespoon fresh thyme, chopped
  • 1 tablespoon garlic, minced
  • 1/2 cup unsalted butter, softened
  • 1 large onion, thinly sliced
  • 1 tablespoon balsamic vinegar
  • 4 slices of Havarti cheese
  • 4 fresh hoagie rolls or baguettes
  • Fresh arugula or spinach, for garnish

Making the Herb Butter

The herb butter is an essential component of this sandwich, providing rich flavor and moisture that enhances the steak. Here’s how to make it:

  1. In a medium bowl, combine the softened butter, chopped rosemary, chopped thyme, minced garlic, salt, and pepper.
  2. Mix well until all ingredients are thoroughly incorporated.
  3. Transfer the herb butter onto a piece of plastic wrap and shape it into a log. Wrap it tightly and refrigerate for at least 30 minutes to firm up.

Caramelizing the Onions

Caramelized onions add a sweet, savory depth to the sandwich. Follow these steps to achieve perfectly caramelized onions:

  1. Heat a large skillet over medium heat and add 2 tablespoons of olive oil.
  2. Add the sliced onions to the skillet and stir to coat them in the oil.
  3. Cook the onions, stirring occasionally, for about 15-20 minutes until they become soft and golden brown.
  4. Once the onions are caramelized, add the balsamic vinegar and stir to combine. Cook for an additional 2-3 minutes until the vinegar has reduced slightly.
  5. Remove the skillet from heat and set the caramelized onions aside.

Cooking the Steak

The steak is the star of this sandwich, and cooking it to perfection is crucial. Here’s how to do it:

  1. Preheat your grill or a skillet over high heat.
  2. Rub the flank steak with olive oil, and season generously with salt and pepper on both sides.
  3. Once the grill or skillet is hot, add the steak and sear for about 4-5 minutes on each side for medium-rare, or until it reaches your desired doneness.
  4. In the last minute of cooking, place slices of Havarti cheese on top of the steak to allow it to melt.
  5. Remove the steak from the heat and let it rest for 5 minutes before slicing. This will help retain the juices.

Assembling the Sandwich

Now comes the fun part—putting together your Herb Butter Steak Sandwich! Follow these steps to create a delicious masterpiece:

  1. Slice the hoagie rolls or baguettes in half horizontally, being careful not to cut all the way through.
  2. Spread a generous amount of the herb butter on the inside of each roll.
  3. Place slices of the rested steak on the bottom half of each roll.
  4. Add a spoonful of the caramelized onions on top of the steak, spreading it evenly.
  5. Top with fresh arugula or spinach for a peppery crunch.
  6. Close the sandwich with the top half of the roll and serve immediately while the cheese is still melty.

Serving Suggestions

This Herb Butter Steak Sandwich with Caramelized Onion and Melty Havarti is perfect for any occasion. Here are some serving suggestions to elevate your meal:

Tips for the Perfect Sandwich

To ensure that your Herb Butter Steak Sandwich is as delicious as possible, keep these tips in mind:

  • Choose high-quality steak for the best flavor. Grass-fed beef often has a richer taste.
  • Let the steak rest after cooking to allow the juices to redistribute, ensuring each bite is juicy.
  • Experiment with different herbs in the butter; parsley or chives can also add a wonderful flavor.
  • Don’t rush the caramelization of the onions; cooking them slowly will enhance their sweetness.

Storing Leftovers

If you happen to have any leftover sandwich ingredients, here’s how to store them:

  • Store the cooked steak in an airtight container in the refrigerator for up to 3 days.
  • Caramelized onions can also be stored in an airtight container in the fridge for up to a week.
  • The herb butter can be kept in the refrigerator for up to 2 weeks or frozen for longer storage.
  • Reheat the steak gently in a skillet or microwave before assembling your sandwich again.

Feel free to get creative with this recipe! Here are a few variations you might enjoy:

  • Swap the Havarti cheese for blue cheese or aged cheddar for a different flavor profile.

  • Incorporate sliced jalapeños or a drizzle of spicy aioli for a kick of heat.
  • Use a different type of bread, such as ciabatta or a pretzel roll, for a unique texture.

Perfect Pairings for Your Sandwich

Looking for the perfect drink to accompany your Herb Butter Steak Sandwich? Consider these options:

  • A bold red wine, such as Cabernet Sauvignon or Malbec, pairs beautifully with the richness of the steak.
