Recipe Help

Can I use dry udon noodles instead of fresh?

Yes, dry udon noodles work well. Adjust cooking time as indicated on the packaging to reach the right tenderness.

How do I make this dish vegan?

Replace ricotta, mozzarella, and Parmesan with vegan cheese or use silken tofu for the creamy layer. Omit dairy ingredients entirely if preferred.

Is sweet soy sauce essential?

Sweet soy sauce balances the broth, but you can substitute with regular soy sauce and a little brown sugar to mimic the flavor.

Can I add extra vegetables to this soup?

Absolutely. Mushrooms and bok choy are excellent additions for more flavor and nutrients, adapting to your tastes.

How do I serve this for gluten-free diets?

Use gluten-free noodles and lasagne sheets, and swap traditional soy sauce for tamari to avoid gluten.

What type of broth should I use?

Low-sodium vegetable broth is recommended to maintain balance between flavors and saltiness in the dish.
