Steak Donburi

If you love Japanese rice bowls but want a method that guarantees perfectly cooked steak every single time, this Sous Vide Steak Donburi is the way to go. Using a sous vide will allow for the steak cooks gently in a temperature-controlled water bath until it becomes melt-in-your-mouth tender. After a quick sear, it’s sliced over warm Japanese rice and finished with a savory donburi sauce.

The beauty of the sous vide method is that it’s nearly foolproof—no babysitting, no overcooking, and no stress. While the steak cooks, you’re free to prep your toppings, make the sauce, or simply relax. Perfect results, every time.

Ingredient Breakdown

• Steak (Ribeye or Striploin) – These cuts stay tender and juicy after sous vide, with just enough marbling for rich flavor. The consistent temperature makes them nearly impossible to overcook.
• Garlic – Infuse subtle aromatics into the steak as it cooks slowly. Not overpowering—just enough to give it a restaurant-style finish.
• Soy Sauce & Mirin – These two create the essential Japanese donburi flavor: salty, sweet, glossy, and rich. They soak into the rice beautifully.
• Sake – Adds depth and umami. Helps balance the sweetness and saltiness of the sauce.
• Butter – Adds umami to finish the sauce without overpowering the steak.
• Short Grain Rice – Warm Japanese short-grain rice acts as the perfect base. Perfectly sticky, fluffy, and able to absorb the sauce and steak juices beautifully.
• Egg – An egg yolk or onsen egg adds creaminess and richness when cracked over the bowl.

Step-by-Step Instructions

1. Prep the Steak

• Pat the steak dry and season generously with salt and black pepper.
• Place it in a zip-top or vacuum-sealed bag with the garlic and thyme.
• Press out as much air as possible – I used a straw to suck out the air

2. Sous Vide in the Rice Cooker

• Fill your multicooker with water.
• Select Sous Vide → 131°F / 55°C for medium rare.
  • 129°F / 54°C for rare
  • 140°F / 60°C for medium
• Submerge the sealed steak.
• Cook for 2 hours.

3. Make the Donburi Sauce

Combine soy sauce, mirin, sake, and sugar in a small pot. Heat until the sugar dissolves. Cook until the sauce is slightly thickened and glossy. Set aside.

4. Sear the Steak

• Remove the steak from the bag and pat it VERY dry.
• Heat a pan on high with a little oil.
• Add butter and sear the steak 30–45 seconds per side, just until browned.
• Let rest for 5 minutes before slicing.

5. Assemble the Donburi

• Add hot rice to a bowl.
• Place sliced steak on top.
• Spoon donburi sauce over the steak and rice.
• Add toppings:
  • green onions
  • soft-boiled egg or onsen egg
  • optional chili powder or chili oil

If you don’t have sous vide or want to make stove top steak

• Bring steak to room temperature (10–15 minutes).
• Pat dry very well.
• Season generously with salt & pepper.
• Heat a pan over medium-high heat until hot.
• Add a little oil.
• Sear 2–3 minutes per side for medium-rare.
• Add 1 tbsp butter + garlic at the end (optional).
• Baste the steak with the melted butter for 30 seconds.
• Rest 5 minutes, then slice.

Tips for Success

• Patting the steak dry before searing ensures a beautiful crust.
• Don’t skip resting the steak—this keeps the juices inside.
• Save the liquid from the sous vide bag and add a spoonful to the sauce for extra richness.
• For extra shine, drizzle melted butter over the steak at the end.
