Step 1: Prep the Zucchini
If using shredded zucchini, place it in a clean kitchen towel and squeeze out as much moisture as possible. If sliced, lay slices on paper towels and pat dry.
Step 2: Sauté the Onions
In a skillet, heat butter or olive oil over medium heat and sauté the diced onions until soft and lightly golden. Set aside to cool.
Step 3: Mix the Base
In a large bowl, beat the eggs. Stir in the shredded cheese, seasonings, sautéed onions, drained zucchini, and about half the breadcrumbs.
Step 4: Assemble the Casserole
Pour the mixture into a greased 8×8-inch or 9×13-inch baking dish (depending on how thick you want it). Sprinkle the remaining breadcrumbs and a bit more cheese on top.
Step 5: Bake
Bake at 375°F (190°C) for 30–35 minutes, or until golden on top and set in the center. A knife inserted should come out clean.
Step 6: Cool & Serve
Let it sit for 5–10 minutes before slicing. Serve warm and enjoy the cheesy zucchini goodness!
