18 Summer Casserole Recipes to Use Up All Those Leftover Veggies

1. Layered Zucchini Corn Casserole: Summer comes to this casserole in the form of layers of zucchini slices, corn and fresh jalapeños. Plus, don’t forget the crave-able goodness from two types of cheese and a hefty dose of garlic. (via From a Chef’s Kitchen)

2. Hatch Green Chile and Tomato Egg Casserole: Whether you have it for dinner or for brunch, this hearty casserole-meets-strata is the perfect anytime dish.

3. Chicken Penne Casserole With Corn and Zucchini: We had to include at least one creamy pasta casserole, but you can feel good about going for seconds since it includes plenty of veggies. Plus, that creamy sauce is made with a whole wheat flour white sauce instead of cream. Bonus: All those summer vegetables and whole wheat pasta further boosts this one’s health quotient. (via The Seasoned Mom)4. Tomato Cobbler: This dish had us at “cobbler.” A base of juicy fresh tomatoes (a mix of heirloom and grape varieties) makes this the ultimate late summer casserole. The biscuit topping can hold its own against all that tomatoey goodness too — the dough is flavored with whole grain mustard and thyme. (via Saving Room for Dessert)

5. Roasted Cauliflower, Tomato and Goat Cheese Casserole: Roasting the cauliflower before mixing it into the casserole adds caramelized flavor notes to this dish.

10. Roasted Garlic Ratatouille: You may feel like a bit of a show-off bringing something this gorgeous to the potluck, but all you need is a sharp knife and a good playlist to make it.
