Equipment

  • 8x8-inch baking dish
  • Cooking spray
  • Small bowl

Ingredients
  

  • 2 medium zucchini and/or summer squash sliced
  • 2 medium tomatoes sliced
  • 1/4 cup finely chopped shallot
  • 1/4 cup chopped fresh basil plus 2 tablespoons, divided
  • 1 tablespoon extra-virgin olive oil
  • 1/2 teaspoon salt
  • 1/4 teaspoon ground pepper
  • 3/4 cup shredded fresh mozzarella cheese (3 ounces)
  • 1 dash balsamic vinegar for optional drizzle

Instructions
 

  • Preheat your oven to 400°F. Lightly grease an 8x8-inch (or similar-sized) baking dish with cooking spray.
  • Layer the zucchini and tomato slices in the baking dish like overlapping shingles. If needed, slice the vegetables in half to fit better.
  • In a small bowl, combine the chopped shallot, 1/4 cup basil, olive oil, salt, and pepper. Stir well.
  • Spoon the shallot and basil mixture over the layered vegetables. Sprinkle the shredded mozzarella evenly on top.
  • Bake for about 30 minutes, or until the vegetables are tender, and the cheese is melted and starts to brown slightly.
  • Sprinkle the remaining 2 tablespoons of basil on top for a finishing touch. For extra flavor, drizzle with balsamic vinegar just before serving.

Notes

For a perfectly cooked casserole, pat zucchini and tomatoes dry to reduce extra moisture. Add parmesan for sharper flavor or experiment with other veggies like eggplant or mushrooms.
