Curry Udon Calories and a Cozy One-Pot Recipe

Curry udon is a Japanese noodle soup of thick udon noodles in a savory curry broth, often with chicken, onion, and scallions. This version gets its warming flavor from Japanese curry roux and dashi, with a little soy and mirin for depth; it makes four generous bowls at about 600 calories per serving, depending on the noodles and roux you use.

Ingredients

4 portions frozen or fresh udon noodles, about 28 oz (800 g)
12 oz (340 g) boneless, skinless chicken thighs, cut into ¾-inch (2 cm) pieces
1 medium yellow onion, about 5 oz (150 g), thinly sliced
1 small carrot, about 3½ oz (100 g), cut into thin half-moons
1 tablespoon (15 ml) neutral cooking oil
4 cups (960 ml) Japanese dashi stock, homemade or prepared from instant dashi
4 Japanese curry roux cubes, about 2.8 oz (80 g), broken into smaller pieces
2 tablespoons (30 ml) soy sauce
1 tablespoon (15 ml) mirin
1 teaspoon (4 g) granulated sugar
1 tablespoon (8 g) cornstarch
2 tablespoons (30 ml) cold water
2 scallions, about 1 oz (30 g), thinly sliced
1 teaspoon (5 ml) toasted sesame oil, optional, for serving
Shichimi togarashi or Japanese chili flakes, optional, for serving

Instructions

Prepare the ingredients, 15 minutes. Slice the onion and carrot, cut the chicken into evenly sized pieces, and measure the stock and seasonings. Breaking the roux into smaller pieces now helps it melt smoothly later. If using frozen udon, keep it frozen until you are ready to heat it.
Brown the chicken and soften the vegetables, 5 minutes. Warm the oil in a medium Dutch oven or heavy saucepan over medium-high heat. Add the chicken in one layer and cook for about 2 minutes, turning once, until the outside is no longer raw-looking; it does not need to be cooked through yet. Add the onion and carrot and cook for 3 minutes, stirring, until the onion begins to soften.
Simmer in dashi, 9 minutes. Pour in the dashi, soy sauce, mirin, and sugar. Bring the liquid to a gentle boil, then lower the heat to maintain a steady simmer. Cook uncovered for 8 minutes, stirring occasionally. Check a larger chicken piece with a food thermometer; USDA FSIS lists 165°F (74°C) as the safe minimum internal temperature for poultry. If it has not reached that temperature, simmer and check again in short intervals.
Thicken the curry broth, 2 minutes. Turn the heat to low. Stir in the curry roux a little at a time until dissolved. Mix the cornstarch with the cold water in a small cup, then stir the slurry into the pot. Let the broth bubble gently for about 1 minute, stirring, until it lightly coats a spoon. Avoid a hard boil, which can make the roux stick to the bottom. Taste before adding salt; roux and soy sauce are already seasoned.
Heat the noodles and serve, 4 minutes. Cook the udon according to its package directions, usually by simmering or briefly boiling until hot and separated. Drain well. Divide the noodles among four bowls, ladle the chicken curry broth and vegetables over them, and finish with scallions. Add a few drops of sesame oil or a pinch of shichimi togarashi if desired. The final minute is for dividing and garnishing; the noodle heating itself takes about 3 minutes.

Tips

Use the package as your noodle guide. Fresh, frozen, and shelf-stable udon have different heating instructions. The goal is hot, springy noodles, not prolonged boiling. Cook them separately from the curry so their starch does not make the broth gluey, and drain them well to keep the soup’s flavor balanced.
Choose a practical dashi substitute. Instant dashi is an easy pantry option; prepare 4 cups (960 ml) according to its package directions. For a vegetarian bowl, use kombu-and-shiitake dashi or a mild vegetable broth. Vegetable broth is less distinctly Japanese and can taste sweeter, so taste the finished soup before adjusting the soy sauce.
Keep the roux from scorching. Curry roux contains starch and fat that can settle at the bottom. Lower the heat before adding it, stir until fully dissolved, and scrape the base of the pot as you mix. Japanese curry roux comes in different heat levels and saltiness, so use the package’s suggested amount as a starting point if your brand’s cubes are unusually large.
Adjust the thickness gradually. This recipe makes a lightly thickened broth that clings to udon without becoming gravy. Add the cornstarch slurry a little at a time; you may not need every drop if your roux has already thickened the soup. If the broth gets too thick, stir in hot water or dashi, a tablespoon at a time.

Serving Suggestions

Serve curry udon as a filling meal in wide, deep bowls, with chopsticks for the noodles and a soup spoon for the broth. A small side of quick-pickled cucumber, plain steamed greens, or a crisp cabbage salad provides a cool, fresh contrast to the warm curry. If you are setting out toppings, keep them simple: sliced scallions, shichimi togarashi, toasted sesame seeds, or a little beni shoga (pickled red ginger) all work without obscuring the broth.

The calorie estimate is approximately 600 per serving, calculated as one quarter of this recipe and including the chicken, noodles, oil, and roux. It is an estimate rather than a lab analysis: udon portion size and the nutrition information on curry roux packages can shift the total. For a more accurate count with your ingredients, add the calories listed on each package and divide the total by four. Adding a soft-boiled egg, extra chicken, or another portion of noodles will raise the total; extra vegetables in place of some noodles will change it in the other direction.

Variations

Make it vegetarian. Replace the chicken with 8 oz (225 g) sliced mushrooms and 7 oz (200 g) firm tofu, cut into cubes, and use kombu-shiitake dashi or vegetable broth. Brown the mushrooms first so they release some moisture and develop savory flavor, then add tofu with the stock. Check the curry roux label, because some varieties contain meat-derived ingredients; a vegetarian roux or curry seasoning thickened with a little extra cornstarch is a suitable alternative. The broth will taste earthier and less chicken-forward.

Use pork or beef. Replace the chicken with 12 oz (340 g) thinly sliced pork or beef. Briefly brown the slices, then simmer until cooked through. If using ground meat, cook it completely while browning and break it into small pieces. The recipe’s chicken timing does not apply exactly to different cuts, so use a thermometer as appropriate: ground meat should reach 160°F (71°C), while whole cuts of pork or beef should reach 145°F (63°C) and rest for 3 minutes. Thin slices cook quickly, so avoid simmering them longer than needed.

Make it more vegetable-forward. Add 4 oz (115 g) sliced shiitake mushrooms with the onion, or stir in 2 cups (60 g) baby spinach during the last minute. You can also add 1 cup (130 g) small cauliflower florets; simmer them in the dashi until tender before dissolving the roux. Keep the total vegetables moderate so the liquid still covers the noodles when served.

Control the heat and richness. Choose mild, medium, or hot Japanese curry roux to suit your preference. For extra heat, add chili flakes at the table; this is easier to adjust than making the whole pot too spicy. For a richer broth, stir in ¼ cup (60 ml) unsweetened oat milk or dairy milk after the roux has dissolved, keeping the pot below a boil. The result is creamier and less sharply savory, so taste before adding any more seasoning.

Storage and Reheating

For the best texture, store the noodles and curry broth separately when possible. Transfer them to shallow containers and refrigerate within 2 hours of cooking. The broth with chicken keeps for 3–4 days in the refrigerator; cooked udon is best within 2–3 days because it softens as it sits. If you have already combined them, refrigerate the leftovers promptly and expect the noodles to absorb broth and become softer.

Reheat only the portion you plan to eat. Warm the broth and chicken in a saucepan over medium heat, stirring and adding a splash of water or dashi if it has thickened. Heat leftovers to 165°F (74°C), checking the center with a food thermometer. Reheat noodles separately in simmering water for a short time, drain, and put them in a bowl before adding the hot broth. You can also microwave a serving in a covered, microwave-safe bowl, stirring partway through and checking that it reaches 165°F (74°C). Avoid repeatedly cooling and reheating the full pot.

Frequently Asked Questions

How many calories are in curry udon?
This recipe has about 600 calories per serving when divided into four bowls. The number varies with the brand and amount of udon and curry roux, as well as any toppings or extra protein. Restaurant and packaged versions can use different portions and richer broths, so their calorie counts may not match this estimate.

What makes curry udon different from Japanese curry rice?
Both can use Japanese curry roux, but curry udon is served with thick wheat noodles in a broth that is looser than the sauce commonly spooned over rice. Dashi gives the noodle soup a savory, stock-based character. Home and regional versions vary: some are quite brothy, while others are thick enough to cling closely to the noodles.

Can I make the curry broth ahead?
Yes. Cook the broth and chicken, cool and refrigerate them promptly, then cook the udon when you are ready to eat. The broth may thicken as it chills, so loosen it with a little water or dashi as it reheats. Keeping the noodles separate helps them retain a springier texture.

Can I use curry powder instead of Japanese curry roux?
You can, but curry powder alone will not give the broth the same thickness or the rounded, mildly sweet flavor of roux. For a substitute, bloom 1 tablespoon (6 g) curry powder in the pan after the vegetables soften, then add the stock. Thicken the broth with a cornstarch slurry, adjusting gradually, and season with soy sauce and a small amount of sugar to taste. Curry powders vary, so begin with less if yours is strongly flavored.

Why is my curry udon broth too thick or too salty?
Roux brands differ in concentration, and the noodles can also release starch if cooked directly in the soup. Add hot water or dashi a little at a time to thin the broth. If it tastes too salty, add more unsalted stock or water rather than more sugar, and avoid adding extra soy sauce until you have tasted it. Cooking noodles separately also helps keep the broth’s texture predictable.

Can I freeze curry udon?
The broth and chicken can be frozen in an airtight container for up to 2 months for best quality, but the udon is better cooked fresh. Thaw the broth in the refrigerator, reheat it until it reaches 165°F (74°C), and prepare fresh noodles for serving. Frozen and thawed vegetables may be softer, but the curry broth will still be useful for a quick meal.
