A comforting fusion soup combining the hearty layers of lasagne with chewy udon noodles and a sweet soy broth, perfect for cozy evenings.

I first made this soup on a rainy evening craving both pasta and noodles. Combining lasagne cheese layers with soft udon in a sweet soy broth surprised my family—it became an instant favorite!

  • Vegetables: 1 medium carrot (julienned), 1 small zucchini (sliced into half-moons), 1 cup (60 g) baby spinach, 1/2 cup (50 g) frozen peas, 2 green onions (thinly sliced)
