Why You Will Love This Recipe
You’ll fall in love with Kake Udon for its rich umami flavor, which comes from the dashi broth—a staple in Japanese cuisine. The broth is light yet deeply satisfying, complementing the thick, slurp-worthy udon noodles perfectly. Plus, this recipe is incredibly easy to prepare, making it accessible even for beginner cooks. In just about 30 minutes, you can whip up a wholesome meal that fits well into vegetarian or gluten-free diets (with appropriate substitutions). It’s not just a dish; it’s a warm hug in a bowl!
Tips and Tricks
- Use Fresh Udon: If possible, opt for fresh udon noodles over dried ones for the best texture. Fresh noodles will cook faster and have a chewier bite.
- Make Your Own Dashi: For a more authentic flavor, consider making your own dashi using kombu (seaweed) and bonito flakes. This will elevate your broth to a whole new level.
- Prep Toppings in Advance: Chop your vegetables and prepare any proteins ahead of time. This will streamline the cooking process and make dinner come together faster.
- Experiment with Broth: If you’re feeling adventurous, try adding a splash of soy sauce or mirin for extra depth, or go for a miso-based broth for a different flavor profile.
Make Ahead Tips
You can prepare the dashi broth in advance and store it in the refrigerator for up to three days. Cooked udon noodles can also be stored in an airtight container for about 2-3 days. Just reheat them gently before serving. If you want to save time on weeknights, consider chopping vegetables and proteins ahead of time and storing them separately in the fridge.

Recipe Variations
- Spicy Kake Udon: Add a spoonful of chili paste or chili oil to your broth for a spicy kick.
- Vegetarian Option: Use vegetable dashi or miso broth instead of fish-based dashi.
- Protein Additions: Top your udon with grilled chicken, shrimp, or tofu for added protein.
- Seasonal Vegetables: Incorporate seasonal vegetables like bok choy in the spring or root vegetables in the fall.
How to Serve
Serve your finished Kake Udon in a large, deep bowl for a hearty presentation. Garnish with thinly sliced scallions, a sprinkle of shichimi togarashi (Japanese seven-spice), and a dash of sesame oil for added flavor. For a touch of color, you can also add a few slices of nori or a soft-boiled egg on top. Pair your udon with a side of pickled ginger for an authentic experience.

Pairing Suggestions
For a delightful drink pairing, consider serving your Kake Udon with a chilled glass of sake or a light Japanese beer. Alternatively, a warm cup of green tea complements the flavors beautifully. As for side dishes, you can enjoy it with a light salad or some tempura vegetables for a satisfying meal.
How to Store
Leftover Kake Udon can be stored in an airtight container in the refrigerator for up to 3 days. The noodles may absorb some of the broth; when reheating, add a splash of water or broth to loosen the mixture. You can freeze the broth separately from the noodles for up to a month. When you’re ready to enjoy it, thaw the broth in the refrigerator overnight and reheat gently on the stovetop.
Equipment Needed
- Large pot for boiling noodles
- Medium saucepan for the broth
- Ladle for serving
- Sharp knife and cutting board for preparing toppings

Dietary Adaptations
To make Kake Udon vegan, simply replace the dashi with a vegetable broth and skip any meat toppings. For gluten-free options, look for gluten-free udon noodles or substitute with rice noodles. Check labels on soy sauce to ensure it’s gluten-free if needed.
Seasonal Adaptations
In the spring, add fresh green onions and snap peas for a vibrant touch. During winter, consider using hearty vegetables like shiitake mushrooms or bok choy for warmth and nutrition. In the fall, a sprinkle of pumpkin or squash can bring a seasonal twist to your udon soup.
