What is Crab Hot Pot?

Crab Hot Pot, known as Kani Nabe, is a traditional Japanese communal meal where fresh crab and seasonal vegetables are gently simmered in a light broth made from dashi, kombu, soy sauce, mirin, and sake. The broth enhances the crab's natural sweetness without overpowering it, creating a refined and comforting dish.

Each diner serves themselves directly from the shared pot, making Kani Nabe both interactive and memorable.

Preparation Time

  • Prep Time: 20 minutes
  • Cook Time: 25 minutes
  • Total Time: 45 minutes

Servings: 4

Step 1: Prepare the Broth

In a donabe or large pot, combine:

  • Dashi stock
  • Kombu
  • Soy sauce
  • Mirin
  • Sake
  • Salt

Heat gently until it begins to simmer.

Remove the kombu just before the broth reaches a boil.

Step 2: Prepare the Crab

If necessary, rinse the crab legs under cold water.

Use kitchen scissors to make shallow cuts in the shells, making them easier to eat after cooking.

If using cooked crab, it only needs to be heated through in the broth.

If using raw crab, ensure it cooks completely.

Step 3: Arrange the Ingredients

Neatly arrange the crab, tofu, napa cabbage, mushrooms, leek, carrots, daikon, and chrysanthemum greens in the simmering broth.

This traditional presentation allows everything to cook evenly while creating a beautiful centerpiece.

Step 4: Simmer

Cook gently over medium heat for 8–12 minutes, depending on whether the crab is raw or pre-cooked.

Add the leafy greens during the last few minutes of cooking.

Avoid vigorous boiling, as it can toughen the crab meat.

Step 5: Serve

Ladle the hot broth and ingredients into individual bowls.

Serve with ponzu sauce, grated daikon, yuzu kosho, or shichimi togarashi for extra flavor.

Step 6: Finish with Rice or Noodles

After most of the crab and vegetables have been enjoyed, add cooked rice or udon noodles to the remaining broth.

Simmer until heated through, allowing the rice or noodles to absorb the sweet crab-infused broth.

This traditional finishing dish is often called zosui when made with rice.

Garnish

Complete your Crab Hot Pot with:

  • Chopped green onions

  • Use the freshest crab available for the sweetest flavor.

  • Cut the vegetables into similar sizes for even cooking.

  • Save the remaining broth for rice or noodles—it becomes even more flavorful.
  • Taste the broth before serving and adjust the seasoning if necessary.

Frequently Asked Questions

What type of crab is best for Kani Nabe?

Snow crab, king crab, Dungeness crab, or blue crab all work well. Fresh crab offers the sweetest flavor, but high-quality frozen crab is also excellent.

Can I use cooked crab?

Yes. Cooked crab only needs to be heated through in the broth, making it a convenient option.

Why is kombu removed before boiling?

Boiling kombu for too long can create a bitter taste and affect the clarity of the broth. Removing it just before the broth reaches a boil preserves its delicate umami.

What vegetables are traditionally used?

Napa cabbage, shiitake mushrooms, enoki mushrooms, daikon radish, carrots, tofu, leek, and chrysanthemum greens are common choices.

What should I do with the leftover broth?

The remaining broth is highly prized. Add cooked rice to make zosui or simmer udon noodles in the broth for a delicious final course.
