Behind the Recipe

It all started during one bountiful summer when the garden zucchini just wouldn’t stop growing. Faced with more squash than I knew what to do with, I began experimenting. I remember tossing together a few simple ingredients—some cheese, eggs, a handful of herbs—and what came out of the oven was pure magic. Over time, this recipe became a family staple, shared at potlucks, cozy brunches, and even weeknight dinners when time was tight. It’s a go-to for when I want something hearty, wholesome, and just a bit nostalgic.

Recipe Origin or Trivia

Zucchini casseroles have roots in European kitchens, particularly Italian and Mediterranean cuisines where fresh vegetables are celebrated. The idea of shredding zucchini into a dish likely gained traction during post-war frugality when home gardeners needed to stretch seasonal produce creatively. While Americanized versions often include breadcrumbs and cheese, traditional Mediterranean variations might feature herbs like thyme and oregano, olive oil, and even tangy feta. This recipe bridges those worlds—simple, flavorful, and adaptable to what you have on hand.

Chef’s Pro Tips for Perfect Results

Getting this casserole just right is all about balance and texture. Here’s how to master it every time:

Salt and drain the zucchini: Zucchini holds a lot of water. Let it sit salted in a colander for 10 minutes, then squeeze out the excess to avoid a soggy casserole.
Use freshly grated cheese: Pre-shredded cheese often has anti-caking agents that prevent melting. Grate it fresh for creamier results.
Bake uncovered: This helps achieve that golden crust on top while keeping the inside moist.

Let it rest before serving: Like lasagna, giving the casserole 5–10 minutes to settle helps it slice cleanly and hold its shape.
Add herbs last minute: Fresh herbs retain their brightness best when stirred in just before baking.

Kitchen Tools You’ll Need

You won’t need anything fancy, just a few trusty kitchen staples:

Grater: For shredding the zucchini into thin, tender strands.

Colander: Essential for draining excess moisture from the zucchini.

Baking Dish (9×13″): The perfect size to bake this casserole evenly.
