- Thinly sliced beef: I used pre-sliced beef labeled “shabu shabu” from the Japanese market. If you can’t find it, you can slice ribeye or chuck steak yourself at home. Just follow my easy tutorial How To Slice Meat Thinly.
- Komatsuna: If you can’t find this Japanese mustard spinach at the Japanese market, you can use regular spinach instead.
- Maitake mushrooms: I love using these mushrooms because they hold up well in sautés and have a delicious flavor. If you can’t find them, you can use brown crimini mushrooms or king trumpet (eryngii) mushrooms.
- Ponzu: This refreshing citrus-based sauce has a tangy and savory flavor. You can find it at Japanese and Asian markets, but I highly recommend making your own Homemade Ponzu Sauce if you can. It is so easy and tastes better than bottled! If you don’t have ponzu, try my quick version with equal parts soy sauce and fresh lemon juice plus a touch of mirin for sweetness.


How to Make Butter Ponzu Beef
Preparation
Step 1 – Cut the beef and komatsuna. Slice them into 2-inch (5-cm) sections.


Step 2 – Prep the mushrooms and garlic. Break the maitake into smaller, bite-sized clusters. Crush the garlic.


Cooking
Step 3 – Sauté the komatsuna stems and mushrooms. Start cooking the thick stems, then add the maitake and toss to coat with oil.


Step 4 – Add the leafy greens. When the maitake are almost done, add the komatsuna leaves and sauté until just wilted. Transfer to a serving dish.


Step 5 – Cook the beef. Stir in the garlic as the butter melts, then add the sliced beef. Separate the slices so it cooks evenly.


Step 6 – Season with ponzu. When the beef is no longer pink, pour in the ponzu sauce. Stir to combine and heat until bubbling.


Assemble
Step 7 – Plate and serve. Transfer the beef onto the sautéed vegetables and spoon the pan sauce on top. Sprinkle with optional sesame seeds and serve.


Nami’s Recipe Tips
- Cook the komatsuna stems and leaves separately – The tough stems take longer to cook, so throw them in the pan first. To keep the leafy greens from overcooking, I like to add them later and sauté until they’re just wilted.
- Don’t overcook the maitake – I cook these mushrooms until they’re tender but still firm. I know they’re done when they develop a light golden brown color.
- Don’t burn the garlic – You don’t need to cook the garlic very long in the butter. Simply toss the two together for a few seconds in the pan, then add the beef.
- Separate the beef slices – I use cooking chopsticks to separate the layers of sliced beef in the pan. All the meat has contact with the hot cooking surface this way, so everything cooks evenly.
- Don’t overcook the beef – It doesn’t take long to cook this paperthin meat. I keep the beef tender by sautéing until it’s no longer pink, then quickly adding the ponzu. As soon as it bubbles, I turn off the heat.
Variations and Customizations
- Use thin-sliced pork. For a change of pace, I like to make this dish with pre-sliced pork loin, too.
- Sear scallops. Quickly fry fresh scallops in butter for a delicious seafood variation.
- Try other greens. Some fiber-rich veggies that work include conventional spinach, Shanghai (baby) bok choy, or green cabbage. You could even toss in slivers of green or red bell pepper.
- Use a mushroom medley. Why choose just one type? Try a mix of your favorite mushroom varieties.
- Add minced ginger. Fresh ginger adds a zesty aroma and flavor that pairs well with garlic.
- Mix in other aromatics. Try adding chopped garlic chives, onion wedges, or sliced scallions/green onions. You can even garnish with crispy garlic chips.
- Drizzle with toasted sesame oil. It adds a wonderful aroma and nutty flavor to the dish.
What to Serve with Butter Ponzu Beef
- With rice – Serve a bowl of my irresistible Japanese Corn Rice.
- With soup – Pair it with comforting and restorative Easy Japanese Egg Drop Soup.
- With a vegetable side – My colorful Namasu (Daikon and Carrot Salad) is a bright and tangy addition to any meal.
- With pickles – Japanese Pickled Cabbage is crunchy, refreshing, and goes with everything!

Frequently Asked Questions
If you don’t have ponzu, whisk up my quick version with equal parts soy sauce and fresh lemon juice plus a touch of mirin for sweetness. You do not need to add sake. Instead of lemon, try a combination of citrus like lemon juice, orange juice, and/or grapefruit juice. I don’t recommend lime juice. If you happen to have a few tbsp yuzu juice, you can certainly use that! You’ll need about 4 tablespoons of sauce for this dish. You can use any leftovers to whisk up a ponzu dressing to drizzle on tossed greens, thick slices of avocado, or broiled salmon.
If your thin-sliced beef is frozen or partially frozen, the slices won’t separate easily and it will cook unevenly. Please defrost it overnight in the fridge first covered in plastic wrap. Leave it on the countertop to bring up the temperature a bit (it doesn’t have to be at room temperature). Pat dry with paper towels if the beef has released juices while thawing.

Butter Ponzu Beef
Ingredients
- ½ lb thinly sliced beef (chuck or ribeye) (I used shabu shabu beef from the Japanese market; or learn how to slice meat thinly at home)
- 2 cloves garlic
- 1 bunch komatsuna (3 oz, 85 g; or spinach)
- 1 package maitake mushrooms (3.5 oz, 100 g)
- 1 Tbsp neutral oil
- ¼ tsp Diamond Crystal kosher salt (divided)
- ¼ tsp freshly ground black pepper (divided)
- 1 Tbsp unsalted butter
- 4 Tbsp ponzu
- ½ tsp toasted white sesame seeds (optional, for garnish)
Instructions
- Gather all the ingredients.
- Cut ½ lb thinly sliced beef (chuck or ribeye) into 2-inch (5 cm) sections.
- Crush 2 cloves garlic (I use a garlic press). Slice 1 bunch komatsuna crosswise into 2-inch (5 cm) pieces. Separate the thick stems and leafy greens into different piles.
- Open 1 package maitake mushrooms and cut off the root end. Then, separate them into smaller clusters with your hands. I like to cut the maitake bunch in half with a knife before I break them into small chunks.
To Cook the Vegetables
- Preheat a wok, frying pan, or saucepan (I used a 10¼" carbon steel pan) over medium heat. When it's hot, add 1 Tbsp neutral oil. When the oil is hot, add the komatsuna stems and sauté to coat with oil.
- Add the maitake mushrooms. Toss to combine and coat with oil. Sauté until they develop a bit of color and become tender, with no stiffness and the center just cooked through—avoid overcooking so they retain their shape.
- When the mushrooms are almost done, add the komatsuna leaves. Season with ⅛ tsp kosher salt and ⅛ tsp freshly ground black pepper and toss it all together. Reserve the remaining salt and pepper to season the beef.
- When the leafy greens are wilted, transfer everything to a serving plate. Clean any remaining food particles from the pan with a paper towel.
To Cook the Beef
- Add 1 Tbsp unsalted butter and the crushed garlic to the pan. Stir briefly to coat the garlic in the melted butter. Then, add the sliced beef.
- Season with the remaining ⅛ tsp kosher salt and ⅛ tsp ground black pepper. Separate the beef slices (I use cooking chopsticks) so all the pieces come in contact with the hot pan and cook evenly.
- Once the beef is no longer pink, add 4 Tbsp ponzu. Stir to combine well. When the sauce begins to bubble, turn off the heat.
To Serve
- Transfer the beef onto the sautéed vegetables and spoon the pan sauce on top. Sprinkle with ½ tsp toasted white sesame seeds (optional). Serve immediately.
