Tips & Substitutions
For a creamier texture, consider adding a sprinkle of grated cheese to the filling before baking. You can substitute zucchini with yellow squash for a different flavor profile. If you're short on time, pre-chopped frozen corn can save preparation time. Experiment with spices like paprika or Italian seasoning to enhance the dish's flavor.
Serving Suggestions
Serve the zucchini au gratin as a side dish with grilled chicken or fish for a delightful meal. It pairs beautifully with Corn-Zucchini Bake for a cohesive summer spread. A simple green salad dressed with vinaigrette can complement the richness of the gratin, making for a balanced and satisfying dinner.
