For the Zucchini Base

Step-by-Step Instructions
I’m gonna walk you through making this Cheesy Zucchini Casserole like I’m right there in the kitchen with you. I’ve made this so many times, I’ve got a few little tricks up my sleeve to make it foolproof. Let’s dive in!
Step 1: Preheat and Prep
First things first, crank your oven to 375°F (190°C). Grease a 9×13-inch baking dish with a bit of butter or cooking spray. I’ve skipped this step before, and let me tell ya, scraping off stuck casserole is no fun.
Step 2: Sauté the Veggies
Grab a large skillet, heat up 2 tablespoons of olive oil over medium heat, and toss in your sliced zucchini, chopped onion, and minced garlic. Cook for about 5-7 minutes until they’re just tender. I like to stir often so nothing burns, and honestly, the smell at this stage is pure heaven!
Step 3: Mix the Cheesy Base
In a big ol’ bowl, combine 2 cups of shredded cheddar, 1/2 cup of Parmesan, 1 cup of sour cream, and those 2 beaten eggs. Stir it up until it’s nice and smooth. I’ve found that mixing this while the veggies cool a bit stops the eggs from scrambling when you combine everything.
Step 4: Combine and Transfer
Add your sautéed veggies to the cheesy mixture and give it a good mix. Pour it all into your prepared baking dish, spreading it out evenly. This is where I sneak a taste (don’t tell!), because raw Cheesy Zucchini Casserole mix is just too tempting.
Step 5: Top It Off
In a small bowl, mix 1 cup of breadcrumbs with 2 tablespoons of melted butter and 1/2 teaspoon of Italian seasoning. Sprinkle this over the casserole for that golden, crunchy top. I sometimes press it down lightly so it sticks better.
Step 6: Bake to Perfection
Pop the dish into the oven and bake for 30-35 minutes until the top is golden and bubbly. Check it at the 25-minute mark, ‘cause ovens can be sneaky! When it’s done, your Cheesy Zucchini Casserole will look and smell like a cheesy dream come true.
And that’s it! Let it cool for a few minutes before digging in, if you can resist. I never can.
