A cozy bake of zucchini, sweet corn, and mild green chile layered with melty cheese and golden crunch.

Ingredients

    Directions

    This Zucchini, Corn & Chile Casserole is a vibrant, cheesy bake that celebrates the best of summer produce. Sweet corn, tender zucchini, and mild green chile are sautéed with herbs and folded into a creamy egg‑custard base enriched with three cheeses. Topped with buttery, golden panko breadcrumbs, it bakes into a dish that’s crisp on top and comfortingly soft inside. Versatile and crowd‑pleasing, it’s just as at home on a brunch table, served alongside fresh fruit and coffee, as it is for dinner, paired with a crisp salad. It also makes a standout side dish for gatherings, offering a colorful, flavorful way to showcase seasonal vegetables.

    Step1

    Preheat your oven to 375°F and grease a medium 2‑quart baking dish. Husk and wash the corn, then cut the kernels off the cobs. Slice the zucchini into rounds about ½‑inch thick and quarter each slice so they’re bite‑sized. Stem, seed, and dice the green chiles —I'm using Anaheim chiles from the garden; Hatch or poblano will also work beautifully. Dice 1 cup of yellow onion.

    Step2

    Heat a large skillet over medium heat and add 1 tablespoon of olive oil. Add the diced green chile and diced onion, cooking until softened and fragrant, about 5–7 minutes.

    Step3

    Add the corn kernels and quartered zucchini to the skillet, cooking until slightly softened and the corn turns a bright yellow (if using yellow corn), about 5 minutes.

    Step4

    Add 3 minced garlic cloves, 1 teaspoon dried summer savory (or substitute dried basil leaves), and 1 teaspoon dried oregano to the skillet with the corn, zucchini, chile, and onion. Stir in ½ teaspoon black pepper and 1 teaspoon salt, then cook for about 1 minute, or until fragrant. Remove from heat and allow the mixture to cool slightly before combining with the egg custard base.

    Step5

    In a large bowl, combine 2 eggs and ½ cup of heavy cream or whole milk, then beat until smooth and fully combined.

    Step6

    To the bowl, add ½ cup shredded sharp cheddar cheese, ½ cup shredded Monterey Jack cheese, and ½ cup grated Parmesan cheese, stirring until evenly combined.

    Step7

    Add the sautéed vegetables to the bowl with the egg and cheese mixture, stirring until everything is evenly combined.

    Step8

    Pour the mixture into the prepared 2‑quart baking dish, spreading it evenly to ensure the vegetables and custard are distributed throughout.

    Step9

    In a small bowl or measuring cup, melt 3 tablespoons of butter. Add ½ cup of panko breadcrumbs, stirring until the crumbs are evenly coated.

    Step10

    Spread the buttered breadcrumbs evenly over the top of the casserole. Bake in the preheated oven for 30–45 minutes, or until the casserole is set and firm, and the breadcrumbs are golden brown and crispy.

    Step11

    Allow the casserole to cool for 10-15 minutes.

    Step12

    Enjoy!
