Hot Pot Shabu Shabu: Broth, Ingredients and Easy Steps

Shabu shabu is a Japanese hot pot meal in which diners swish thin slices of meat and vegetables through gently simmering broth, then dip them in sauce. This home version pairs beef, tofu, mushrooms, greens, and noodles with a simple kombu broth; the quick cooking keeps the meal lively and lets everyone cook each bite to order.

Ingredients

8 cups (1.9 L) water
1 piece dried kombu, about 4 by 6 inches (10 by 15 cm; roughly 10 g)
1 tablespoon (15 ml) sake, optional
1 pound (450 g) very thinly sliced beef, such as ribeye or sirloin, cut for shabu shabu
8 ounces (225 g) firm tofu, cut into 1-inch (2.5 cm) cubes
8 ounces (225 g) napa cabbage, cut into 2-inch (5 cm) pieces
6 ounces (170 g) shiitake mushrooms, stems trimmed and caps halved if large
6 ounces (170 g) enoki mushrooms, root ends removed and clusters separated
1 bunch (about 5 ounces/140 g) spinach or mizuna, rinsed and trimmed
2 scallions (about 30 g), thinly sliced
8 ounces (225 g) dried udon noodles, or 12 ounces (340 g) fresh udon
½ cup (120 ml) ponzu sauce, for dipping
½ cup (120 ml) sesame dipping sauce (goma dare), for dipping
2 tablespoons (30 ml) water, to thin the sesame sauce if needed
1 teaspoon (5 g) toasted sesame seeds, optional garnish

Instructions

Prepare the kombu broth. Add the water and kombu to a wide, heavy pot. Let the kombu soak for 20 minutes while you prepare the ingredients. Set the pot over medium heat and warm until small bubbles appear around the edges, about 8–10 minutes; do not let it boil vigorously. Remove the kombu just before the broth boils. Stir in the sake, if using. Keep the broth at a gentle simmer on a portable burner at the table, or on the stove between batches.
Arrange the ingredients. Place the beef on a chilled platter, separating the slices so diners can pick them up easily. Arrange the tofu, cabbage, shiitake, enoki, spinach, and scallions on another platter. Keep raw beef separate from ready-to-eat foods, and use clean serving plates and utensils. If the slices are not paper-thin, cut them into manageable pieces so they cook quickly and evenly.
Cook the noodles separately. Prepare dried or fresh udon according to its package directions, usually in a separate pot of boiling water. Drain and rinse briefly if the package instructs you to do so, then divide among serving bowls. Cooking noodles separately keeps the hot pot broth from becoming cloudy or starchy. Set out the ponzu and sesame sauce; thin the sesame sauce with a little water if it is too thick.
Cook vegetables and tofu in the broth. Add a few pieces of cabbage, mushrooms, and tofu to the simmering pot. Cook until the cabbage is tender-crisp and the mushrooms are hot and softened, about 3–5 minutes depending on their size. Add spinach near the end; it wilts in about 30–60 seconds. Avoid overcrowding the pot, which can cool the broth and slow cooking.
Swish the beef to cook it. Using clean chopsticks or tongs reserved for raw meat, lower one slice into the simmering broth and move it gently until it is no longer pink, usually 10–30 seconds for very thin slices. The USDA FSIS safe minimum for whole cuts of beef is 145°F (63°C) followed by a 3-minute rest; check a thicker slice with a food thermometer when needed, since color alone is not a reliable measure. Do not put raw-meat utensils back into cooked food. Diners can dip cooked beef in ponzu or sesame sauce.
Finish and eat in rounds. Let each diner cook small batches of ingredients and transfer them to a bowl with noodles and dipping sauce. Add more vegetables and beef as the pot empties, allowing the broth to return to a gentle simmer between additions. If the broth reduces, top it up with hot water; taste before adding salt, since the sauces are already seasoned.

Tips

Buy appropriately sliced beef. Japanese or Korean grocery stores often sell beef labeled for shabu shabu. If unavailable, ask a butcher to slice boneless ribeye or sirloin paper-thin while very cold. Partly freezing a piece of beef for 30–45 minutes can make it easier to slice thinly at home; slice across the grain.
Kombu is easy to substitute. Kombu gives the broth a delicate, savory flavor. If you cannot find it, use 8 cups (1.9 L) unsalted chicken or vegetable broth instead; the result will taste richer and less like a light Japanese kelp broth. Avoid boiling kombu hard, which can make its flavor harsh or its broth cloudy.
Keep the pot at a simmer, not a rolling boil. A hard boil can break up tofu, overcook greens, and make delicate beef tough. Add ingredients in small batches and let the liquid recover its simmer before cooking more.
Handle raw beef carefully. Keep it refrigerated until needed, use separate utensils for raw and cooked food, and discard any raw-meat juices. Do not leave perishable ingredients at room temperature for more than 2 hours, or 1 hour when the temperature is above 90°F (32°C).

Serving Suggestions

Set the pot on a stable, heatproof surface with a portable burner, and make sure the cord or fuel canister is safely positioned according to the appliance instructions. Provide each diner with a bowl, chopsticks, and a small dish of each sauce. Ponzu brings a bright citrus-soy flavor; sesame sauce is creamy and nutty. Offer extra sliced scallions, sesame seeds, or a little grated ginger as optional garnishes.

The udon can go directly into bowls before the meal or be added to the broth after the meat and vegetables are finished. The broth will have picked up flavor from the ingredients, so ladle some into bowls as a simple soup. If serving rice instead, provide about ¾ cup (140 g) cooked rice per person.

Variations

For a mixed-meat pot, replace some or all of the beef with paper-thin pork loin or chicken. Pork and chicken slices must be cooked through; check the thickest piece with a food thermometer. USDA FSIS safe minimum temperatures are 145°F (63°C) with a 3-minute rest for whole cuts of pork, and 165°F (74°C) for poultry.

For a seafood version, use peeled shrimp, firm white fish pieces, or scallops, and cook each until opaque and safely done. Fish should reach 145°F (63°C) according to USDA FSIS; shrimp and scallops should be cooked until firm and opaque. For a vegetarian pot, use vegetable broth, omit the beef, and add extra tofu, mushrooms, napa cabbage, and sliced carrot. Check that the dipping sauces are vegetarian if that matters to your guests.

Storage and Reheating

For best texture, cook only what you expect to eat. Refrigerate leftover cooked beef, vegetables, tofu, and broth within 2 hours in shallow, covered containers; eat within 3–4 days. Store cooked noodles separately if possible, since they can absorb broth and soften. Discard food left out longer than 2 hours, or longer than 1 hour above 90°F (32°C).

Reheat broth to a boil, then add refrigerated cooked ingredients and heat them until steaming hot throughout. USDA FSIS recommends reheating leftovers to 165°F (74°C); check with a food thermometer. Reheat only the amount you plan to serve, rather than repeatedly cooling and warming the full batch. Freeze leftovers in airtight containers for up to 2–3 months for best quality; thaw in the refrigerator and reheat to 165°F (74°C). Do not freeze raw beef that has been thawed unless it was thawed safely in the refrigerator.

Frequently Asked Questions

What does “shabu shabu” mean?
The name imitates the swishing sound of thinly sliced ingredients moving through hot broth. The quick dip-and-cook style is central to the meal.

Can I make shabu shabu without a table burner?
Yes. Simmer the broth on the stovetop and cook ingredients in small batches there, transferring them to bowls. Keep the uncooked beef refrigerated between batches and avoid carrying a pot of hot broth across a crowded table.

Can I prepare the ingredients ahead?
Yes. Cut the vegetables and tofu up to a day ahead and refrigerate them covered. Keep meat in its original packaging or a covered container on the lowest refrigerator shelf, and slice or unwrap it just before serving. Kombu can soak in the measured water in the refrigerator for up to a day.

Is the beef supposed to be rare?
Very thin beef cooks rapidly, and some diners prefer it just cooked through, but doneness should not be judged by appearance alone. For the USDA FSIS safe minimum, whole cuts of beef should reach 145°F (63°C) and rest for 3 minutes; use a thermometer for thicker pieces.

What can I use instead of ponzu or sesame sauce?
For a quick alternative, combine soy sauce with a little lemon or rice vinegar for a tangy dip. For a sesame-style dip, stir tahini with soy sauce and water until pourable. These substitutes are convenient but differ from traditional ponzu and Japanese sesame dipping sauce in flavor and texture.
