Preheat the oven to 400°F (200°C).

Heat a large pot or Dutch oven on medium-high heat. Add the olive oil, then the shallot, garlic, and red pepper flakes, cooking until fragrant, about 1 minute.

Add in the corn, zucchini and a pinch of salt. Cook until beginning to soften, about 3-5 minutes.
04 -
Add 2 cups of the broth, cream, pasta, lemon zest and another good pinch of salt. Bring to a boil. Cook until the pasta is almost al dente, about 15 minutes, stirring occasionally to prevent sticking. Add the remaining cup of broth as needed as liquid evaporates.

Top with mozzarella cheese and bake uncovered until the pasta is fully cooked and the cheese is melted, about 10 more minutes.

Serve immediately while hot.
