Ingredients

For the Steak

  • 1½ lbs flank steak, skirt steak, or ribeye
  • Salt and black pepper to taste
  • 1 tablespoon neutral oil (canola, vegetable, or avocado oil)
  • 2 tablespoons butter
  • 2 cloves garlic, smashed
  • 1 sprig fresh thyme (optional)
For the Miso Butter
  • 3 tablespoons softened butter
  • 1 tablespoon white miso paste
  • 1 teaspoon soy sauce
  • 1 teaspoon honey or brown sugar
  • ½ teaspoon rice vinegar
For the Charred Scallion Noodles
  • 10 oz noodles (udon, ramen, rice noodles, or spaghetti)
  • 1 tablespoon sesame oil
  • 1 tablespoon neutral oil
  • 6–7 scallions, cut into 2-inch sections
  • 2 cloves garlic, minced
  • 1 tablespoon soy sauce
  • 1 tablespoon oyster sauce
  • 1 teaspoon toasted sesame seeds
  • ½ teaspoon chili flakes (optional)
Instructions

Step 1: Make the Miso Butter

In a small bowl, combine the softened butter, white miso paste, soy sauce, honey, and rice vinegar. Mix until smooth and creamy.

Set aside at room temperature. This will melt beautifully over the hot steak.

Step 2: Prepare and Sear the Steak

Pat the steak dry and season generously with salt and pepper. A dry surface helps achieve a deep golden crust.

Heat a large cast-iron skillet over medium-high heat. Add the neutral oil and swirl to coat.
Once the skillet is hot and shimmering, lay the steak down carefully. Sear for 3–4 minutes per side (for medium-rare, depending on thickness). Add butter, garlic, and thyme during the last minute, basting the steak with the melted butter using a spoon.

Remove the steak from the pan and let rest for 10 minutes. Resting ensures the juices redistribute and the steak stays tender.

Step 3: Cook the Noodles

While the steak rests, cook your noodles according to package instructions. Drain and set aside, reserving a splash of noodle water.

Udon or ramen noodles work best, but any noodle with some body will absorb the flavors beautifully.

Step 4: Char the Scallions

Heat sesame oil and neutral oil together in a nonstick or cast-iron skillet over medium-high heat.

Add the scallions in a single layer. Let them cook undisturbed until they begin to char, blister, and soften—about 3–4 minutes. Flip and cook the other side.

Add the minced garlic and cook for 30 seconds, stirring quickly to avoid burning.

Step 5: Make the Noodle Sauce

Reduce heat to medium. Add soy sauce, oyster sauce, sesame seeds, and chili flakes. Toss the scallions in the sauce until glossy.

Add the cooked noodles to the pan, tossing thoroughly to coat. If the mixture feels too thick, add 1–2 tablespoons of noodle water to loosen everything.

The noodles should become shiny, aromatic, and infused with the smoky charred scallion flavor.

Step 6: Assemble the Dish

Slice the rested steak thinly against the grain for maximum tenderness.

Place a generous heap of charred scallion noodles onto plates or bowls. Add sliced steak over the top.

Finish with a spoonful of the miso butter, letting it melt slowly into the warm steak and noodles.

Serve immediately.

Final Thoughts

This Miso Butter Steak with Charred Scallion Noodles is the kind of dish that feels indulgent yet smartly balanced. The miso butter melts into the steak to create a glossy, savory coating, while the charred scallion noodles deliver smoky aromatics and rich umami flavors. Together, they create a fusion of Japanese-inspired comfort with modern steakhouse flair.

It’s a dish that satisfies deeply—perfect for date nights, special dinners, or simply elevating an everyday meal. Once you try miso butter on steak, you’ll wonder how you ever lived without it.

Helpful Tips

1. Don’t skip the steak rest time

Resting ensures juiciness—cutting too soon makes the steak dry.

2. White miso works best

It’s mild, creamy, and blends beautifully with butter.

3. Char the scallions well

That smoky flavor brings dimension to the whole dish.

4. Adjust noodle sauce to taste

More soy for saltiness, more oyster sauce for richness, a splash of vinegar for brightness.

5. Use a hot pan

A very hot skillet creates the best steak crust.

6. Make it spicy

Add chili oil, sriracha, or crushed chili flakes for heat.

7. Leftovers

Store separately for best texture. Reheat noodles with a splash of water.
