My dear friends and food enthusiasts, prepare yourselves for an unforgettable culinary experience with the Wagyu Steak Sandwich Recipe. This sandwich recipe is a mouthwatering combination of savory and sweet flavors that will tantalize your taste buds in all the right ways.

Firstly, let’s talk about the star of this dish – the wagyu steak. It is not just any ordinary steak, mind you. It is a full-blooded, A5 grade wagyu sirloin, known for its incredible marbling and tenderness. Every bite of this steak will melt in your mouth like butter, leaving behind a rich umami flavor.

Secondly, this recipe cleverly pairs the steak with some unusual ingredients like watercress, pear slices, blue cheese crumbles, and capers to cut through the richness of the meat, creating a perfect balance of flavors in your mouth. The peppery crunch of the watercress complements the softness of the steak, while the tangy saltiness of the blue cheese and capers adds depth to every bite.

Thirdly, do not underestimate the role of properly toasted bread in making a fantastic sandwich. In this recipe, we use Japanese milk bread to encase our wagyu beef katsu cutlet (yes, we went there!) that’s breaded and fried to addictively crispy perfection. The result? A crunchy outer layer followed by a soft and pillowy inside.

Last but definitely not least, we cannot forget about the secret weapon – homemade katsu sauce. It is a mixture of Worcestershire sauce, ketchup, soy sauce, honey, and some spices that adds an irresistible sweetness to your sandwich without overpowering any other flavors.

The Recipe How-To

Now, let’s get to the fun part: cooking the perfect wagyu steak sandwich. Follow these steps and you’ll have an irresistible, melt-in-your-mouth masterpiece in no time.


  • 2 Wagyu zabuton steaks, sliced 1/4 inch thick
  • 1/4 cup flour
  • 2 eggs, lightly beaten
  • 2 cups panko bread crumbs
  • Salt and black pepper to taste
  • Olive oil for frying
  • 2 medium onions, sliced thinly
  • 1 teaspoon brown sugar
  • 1 tablespoon balsamic vinegar
  • Salt and black pepper to taste
  • Watercress for garnish (optional)
  • Bread of your choice

Step 1: Prepare the Wagyu beef katsu

To make the beef katsu cutlet, season the Wagyu zabuton steaks with salt and pepper. Coat both sides of each steak in flour, shaking off any excess. Dip into the egg mixture then coat with panko breadcrumbs.

Heat olive oil in a large pan over medium-high heat. Fry the beef katsu cutlets until golden brown on both sides. Set aside on a paper towel to drain any excess oil.

Step 2: Caramelize onions

Add olive oil into another pan over medium heat. Add thinly sliced onions and sauté until the onions become translucent. Then add brown sugar, balsamic vinegar, salt, and black pepper to taste. Cook until the onions are caramelized, stirring occasionally.

Step 3: Toast bread

Lightly toast two slices of bread in a toaster or on a griddle until golden brown.

Step 4: Assemble the sandwich

Place one bread slice on a plate and generously spread mayonnaise on top of it. Add caramelized onions, sliced pear, and blue cheese crumbles. Place Wagyu katsu cutlet on top of all these ingredients then add capers and watercress leaves on top of it. Finish off by either adding another slice of toasted bread or not according to your preference.

Congratulations! You’ve successfully made a delicious Wagyu Steak Sandwich that will satisfy your cravings in one bite. Enjoy your tasty creation!

When it comes to making the perfect wagyu steak sandwich, there are plenty of different substitutions and variations you can make to suit your preferences. Here are a few ideas to get you started:

– Cheese: Instead of blue cheese, you could try using Swiss cheese or cheddar for a milder flavor.

– Greens: If watercress isn’t your favorite, arugula or baby spinach would be great alternatives.

– Fruit: Instead of pear, you could try thinly sliced apple or even fresh strawberries for a sweet twist.

– Sauce: Katsu sauce is essential for the authentic Japanese flavor of this dish, but if you can’t find it at your local grocery store, try making your own by mixing together Worcestershire sauce, soy sauce, and brown sugar. Or switch it up with a creamy dijon mustard sauce.

– Bread: A classic wagyu katsu sando is made with milk bread, but other soft white breads like brioche or even ciabatta can work as well.

– Steak Cut: Although we recommend using either a wagyu zabuton or skirt steak for the best results, rib eye or filet mignon would also work well in this recipe.

Experiment with different ingredients and see what combination works best for you. Remember that cooking is an art and sometimes the best creations come from experimenting with new techniques and ingredients. Get your apron on and bring out your inner chef!

Now that you’ve made this succulent wagyu steak sandwich, it’s time to serve and pair it with your favorite sides and drinks. Remember to serve the sandwich immediately after preparation to maintain the texture and flavor.

One of my favorite ways to serve wagyu steak sandwich is with watercress or arugula salad with thin slices of pear, blue cheese crumbles, and capers. The subtle sweetness of the pear complements the savory taste of the wagyu steak while the saltiness of blue cheese brings out the flavors of the beef. Adding capers gives a tangy twist to this classic pairing.

You can also serve your wagyu sandwich with roasted garlic fingerling potatoes, coleslaw or grilled vegetables like bell peppers, zucchini, and asparagus on the side. It’s a well-balanced meal that offers both protein and greens in one dish.

For drinks, I’d recommend a full-bodied red wine like Cabernet Sauvignon or Merlot to complement the rich flavors of the steak. A refreshing IPA beer or cider would also pair nicely to balance out the richness of the beef.

Finally, don’t forget to garnish your plate with some fresh watercress leaves for an extra pop of color and texture – it makes for a lovely presentation!

Making a delicious Wagyu Steak Sandwich can be time-consuming, but with the right preparation, you can save time and effort. You’ll be glad to know that this sandwich is a perfect make-ahead meal. You can prepare the steak in advance and assemble the sandwich later when you’re ready to eat.

To make ahead, start by cooking your steak according to the recipe instructions. After cooking, slice it thinly and let it cool completely before storing it in an airtight container. Keep it in the refrigerator for up to 3 days.

When you’re ready to assemble the sandwich, take out the steak from the fridge and let it come to room temperature for about 10 minutes. Then simply reheat your steak in a skillet or microwave for a few seconds just until it’s warmed through. Do not overcook as this will cause the meat to lose its juiciness and flavor.

Storing your Wagyu Steak Sandwiches is also quite easy. Wrap them tightly in plastic wrap or aluminum foil and keep them in an airtight container in your fridge for a maximum of three days. Avoid freezing leftover sandwiches with mayonnaise or lettuce as these ingredients don’t freeze well.

Reheating your leftover Wagyu Steak Sandwich is best done by first unwrapping your sandwich and heating it up wrapped in paper towels or a napkin to avoid messy reheatings. This ensures that bread remains warm without becoming soft and soggy.

By following these tips, you can enjoy a warm and flavorful Wagyu Steak Sandwich even when you don’t have much time on hand!

Cooking a perfect wagyu steak sandwich may seem like a daunting task, especially if you are new to cooking beef katsu. The key to achieving a result that is juicy and tender on the inside and crispy on the outside is ensuring you use the right cooking techniques and equipment. Here are some valuable tips that will help you get the best results possible:

1. Choose the Right Wagyu Steak Cut

When making your wagyu steak sandwich, it’s essential to select the right cut of meat. Depending on your preferences, you can choose from a5 grade, fullblood wagyu, and Japanese wagyu sando. Whether you opt for skirt steak, rib-eye or zabuton steak, ensure it’s at least ¾ inch thick to allow for optimal flavor development during cooking.

2. Preheat Your Skillet or Grill

Wagyu steaks cook best when exposed to high heat to create an irresistible crust while keeping the tenderness of the meat. Thus, it’s necessary to preheat your skillet or grill to make sure that you achieve optimal temperatures when cooking.

3. Season Your Wagyu Steak Generously

Season your wagyu steak with salt and pepper as desired; avoid adding too much seasoning since wagyu beef has natural flavors that you don’t want to overpower with too many spices.

4. Use High-Quality Ingredients for Your Sandwich

Making an excellent sandwich requires high-quality ingredients – this includes using fresh watercress, pear slices, blue cheese crumbles, capers, brown sugar caramelized onions, and a delicious katsu sauce made from blending mayo with breadcrumbs.

5. Rest Your Wagyu Steak Before Serving

After cooking your steak, it would be best to let it rest for five minutes before slicing into it. This “resting” period allows moisture to redistribute throughout the meat properly.

6. Serve on Freshly Toasted Bread

For optimal texture when creating your wagyu steak sandwich recipe, be sure to use freshly toasted bread slices such as milk bread or white bread.

By following these tips precisely, you’ll be sure that your wagyu steak sandwich will turn out great every time you prepare it!

A common question that frequently comes up is how to properly serve Wagyu. In my experience, the most effective approach is also the easiest: just stick with salt and pepper seasoning.
