This steak sandwich is a delicious combination of tender, flavorful beef, sweet caramelized onions, and melted Havarti cheese, all layered inside a crusty baguette with a fresh herb butter spread. It’s perfect for a hearty lunch or a satisfying dinner that comes together quickly.

Ingredients

• 1/2 cup unsalted butter (softened)
• 1 tbsp fresh dill (diced)
• 3 garlic cloves
• 1 tbsp oil
• 1 lb steak
• 1 tbsp salt (adjust to taste)
• 1 large yellow onion
• 4 slices Havarti cheese
• 1 baguette

Instructions

1. Step 1: Prepare the herb butter spread by combining softened butter with crushed garlic and diced fresh dill. Mix until evenly combined and set aside.
2. Step 2: Thinly slice the steak into strips. For easier slicing, freeze the steak for a few minutes beforehand.
3. Step 3: Heat a skillet over high heat with oil. Add the steak strips, season generously with salt, and cook until the beef is golden. Remove from the skillet and set aside.
4. Step 4: Slice the onion into half rings. In the same skillet, sauté the onions until they turn golden brown, then remove from heat and set aside.
5. Step 5: Slice the baguette lengthwise and spread the herb butter evenly on both sides of the bread.
6. Step 6: Layer the sliced steak, sautéed onions, and Havarti cheese slices on the baguette.
7. Step 7: Keep the sandwich open-faced and broil for about 2 minutes, or until the cheese is bubbly and melted.
8. Step 8: Serve immediately while the sandwich is warm and enjoy.

Tips & Variations

• Freeze the steak briefly before slicing to get clean, even strips.
• Swap Havarti cheese with provolone or mozzarella for a different melt and flavor.
• Try adding a handful of arugula or spinach after broiling for a fresh, peppery bite.
• Use a crusty sourdough baguette for an extra tangy flavor.

Storage

Store any leftover sandwich components separately in airtight containers in the refrigerator for up to 2 days. Reheat steak and onions gently in a skillet before assembling a fresh sandwich. Avoid reheating the assembled sandwich in the broiler, as bread may become too crispy or burnt.

FAQs

Can I use a different cut of steak?

Yes, tender cuts like ribeye, sirloin, or flank steak work best for this sandwich because they cook quickly and stay juicy when sliced thin.

How do I prevent the bread from getting soggy?

Spreading the herb butter on the bread acts as a barrier to keep moisture out. Also, assemble close to serving time and broil just long enough to melt the cheese without making the bread soggy.

Ingredients

Scale 1x2x3x

Herb Butter

• 1/2 cup unsalted butter (softened)
• 1 tbsp fresh dill (diced)
• 3 garlic cloves (crushed)

Steak Sandwich

• 1 tbsp oil
• 1 lb steak (thinly sliced)
• 1 tbsp salt (adjust to taste)
• 1 large yellow onion (sliced into half rings)
• 4 slices Havarti cheese
• 1 baguette (sliced lengthwise)

Instructions

1. Prepare Herb Butter: In a bowl, combine the softened unsalted butter with the crushed garlic cloves and diced fresh dill. Mix thoroughly until the ingredients are well integrated and the butter has a smooth, consistent texture. Set this herb butter aside for later use.
2. Slice the Steak: To ensure thin and even slices, briefly freeze the steak for a few minutes to firm it up. Then, carefully slice the steak into thin strips, which will cook quickly and evenly in the pan.
3. Cook the Steak: Preheat a skillet over high heat and add 1 tablespoon of oil to coat the surface. Once hot, add the sliced steak and season generously with salt. Cook the steak strips until they turn just golden brown, ensuring they remain tender. Remove from the skillet and set aside.
4. Sauté the Onions: Using the same skillet, add the sliced yellow onions and cook over medium heat, stirring occasionally, until they become golden brown and caramelized. Remove from heat and set aside.
5. Assemble the Sandwich: Slice the baguette lengthwise, then spread the prepared herb butter generously over both cut sides of the bread. Layer the cooked steak strips evenly over the bottom half, followed by the caramelized onions, and top with slices of Havarti cheese.
6. Broil the Sandwich: Keep the sandwich open-faced and place it under a broiler for about 2 minutes, or until the Havarti cheese melts and becomes bubbly. Watch carefully to avoid burning.
7. Serve: Serve the sandwich immediately while warm and the cheese is melted for the best flavor experience.

Notes

• Freezing the steak slightly before slicing makes the process easier and results in thinner slices.
• Adjust the salt seasoning based on your preference and the saltiness of other ingredients.
• Broiling is a quick method to melt cheese and add slight browning—do not leave unattended.
• You can substitute Havarti cheese with other melty cheeses like provolone or mozzarella for variation.
• For a spicier flavor, consider adding a pinch of black pepper or chili flakes to the steak before cooking.
