California Steak Sandwich: A Taste of Sunshine on a Bun

I can still taste it, the memory as vivid as the golden California sun: my first California steak sandwich. It wasn’t in some fancy restaurant, but at a beachside food truck, the air thick with the scent of grilling meat and the crashing waves providing a perfect soundtrack. The simplicity of the ingredients, the explosion of flavors in each bite – tender steak, sweet caramelized onions, peppery arugula, all nestled between slices of perfectly garlicky toast – it was pure culinary poetry. It was more than just a sandwich; it was a taste of California, a memory I cherish. Today, I’m sharing that experience with you.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 20 minutes
• Total Time: 40 minutes
• Servings: 2
• Yield: 2 Sandwiches
• Dietary Type: Omnivore

Ingredients

• 3 tablespoons olive oil
• 2 tablespoons soy sauce
• 1 tablespoon lime juice (or lemon)
• 1 tablespoon brown sugar
• 1 lb flank steak
• ½ teaspoon kosher salt, to taste
• ¼ teaspoon fresh ground black pepper, to taste
• 1-2 sweet onions, circular slices
• 1 cup arugula
• 6 tablespoons butter, softened (3/4 of a stick)
• 2 garlic cloves
• ⅓ cup parsley, flat leafed, finely chopped
• 4 slices bread, your favorite (Texas toast or sliced sourdough recommended)

Equipment Needed

• Large bowl
• Whisk
• Paper towels
• Grill or Broiler
• Sheet pan (if broiling)
• Nonstick griddle or grill pan
• Small metal skewer (optional, for onions)
• Food processor or mixer
• Pan for toasting bread

Instructions

1. Marinate the Steak: In a large bowl, whisk together the olive oil, soy sauce, lime juice, and brown sugar. Add the flank steak to the bowl and toss to ensure it’s fully coated in the marinade. Let the steak marinate for at least 30 minutes, or up to 2 hours in the refrigerator. The longer it marinates, the more flavorful and tender it will become.

2. Prepare the Steak: Remove the marinated steak from the bowl and pat it completely dry with paper towels. This is crucial for getting a good sear on the steak. Season the steak lightly with kosher salt (remember that the soy sauce in the marinade already contains a good amount of salt) and fresh ground black pepper, to taste.

3. Cook the Steak: You have two options for cooking the steak: grilling or broiling.

   • To Grill: Preheat your grill to medium-high heat. Place the seasoned steak on the grill and cook to your desired doneness, about 6 minutes per side for medium-rare. Keep in mind that the cooking time will vary depending on the thickness of your steak. Use a meat thermometer for accuracy: 130-135°F for medium-rare, 135-145°F for medium.
   • To Broil: Preheat your oven broiler to high. Place the seasoned steak on a sheet pan and cook, turning once halfway through, until cooked to your liking, about 6 minutes per side for medium-rare. Again, cooking time will vary.

4. Caramelize the Onions: Cut the sweet onion into four (1-inch thick) circular slices. Carefully remove the outer ring of skin from each slice. Drizzle the sliced onion with a light colored oil (like canola or vegetable oil) and season both sides with steak seasoning or salt and pepper, to taste. Grill the onion slices on a hot grill or on a nonstick griddle for 5 to 7 minutes on each side, until the onion is tender and has begun to caramelize. The natural sugars in the onion will break down and create a deliciously sweet flavor. Chef’s Tip: Using a small metal skewer to hold the onion slices together makes them easier to flip on the grill.

5. Prepare the Garlic Bread: Combine the softened butter, chopped parsley, and garlic cloves in a food processor or with a mixer until the mixture is smooth and well combined. Season with salt and pepper to taste. Spread the garlic butter generously on both sides of each slice of bread. Place the buttered bread in a pan over medium heat and toast until golden brown and crispy, then flip and repeat on the other side. Watch carefully to prevent burning.

6. Season the Arugula: Place the arugula in a bowl. Lightly drizzle with olive oil and season with salt and pepper. Toss gently to coat.

7. Assemble the Sandwich: Now for the best part! Place two slices of the garlic toast on a plate. Top with the seasoned arugula, followed by the sliced steak. Generously top the steak with the caramelized onions, and finally, place the remaining slice of garlic toast on top. Serve immediately and enjoy!

Expert Tips & Tricks

• Don’t overcrowd the pan: When toasting the garlic bread, make sure not to overcrowd the pan. This will ensure that the bread toasts evenly and gets nice and crispy.
• Let the steak rest: After cooking the steak, let it rest for at least 5-10 minutes before slicing. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful steak.
• Spice it up: Add a pinch of red pepper flakes to the garlic butter for a little extra heat.
• Marinate for longer: If you have the time, marinating the steak overnight will result in an even more flavorful and tender sandwich.

Serving & Storage Suggestions

Serve the California Steak Sandwich immediately after assembling. The warm garlic toast, juicy steak, and caramelized onions are best enjoyed fresh.

• Storage: Leftover steak can be stored in an airtight container in the refrigerator for up to 3 days. The garlic butter can also be stored in the refrigerator for up to a week. Arugula is best consumed fresh but can be stored in a plastic bag in the crisper drawer of your refrigerator for 1-2 days.
• Reheating: Reheat leftover steak in a skillet over medium heat or in the microwave. Reheat the garlic bread in a toaster oven or skillet to maintain its crispness.
• Serving Suggestions: Serve with a side of crispy fries, a fresh salad, or creamy coleslaw. A cold beer or a glass of crisp white wine pairs perfectly with this sandwich.

Q: Can I add other toppings to the sandwich?
A: Absolutely! Feel free to add other toppings such as sliced tomatoes, avocado, or roasted red peppers.

Q: Is it possible to marinate the steak for longer than 2 hours?
A: While you can marinate the steak for longer, be aware that marinating it for more than 4 hours could result in the steak becoming mushy in texture.
