What makes this recipe so special is how it transforms humble zucchini into something that tastes almost indulgent.

Recipe Overview
This creamy zucchini casserole is the perfect marriage of fresh garden vegetables and comfort food satisfaction. We’re talking about tender, perfectly seasoned shredded zucchini nestled in a rich, cheesy sauce and topped with a golden, bubbly layer that’s absolutely irresistible.
Difficulty Level: Easy peasy! If you can use a cheese grater and turn on an oven, you’ve got this! Total Time: About 1 hour (most of that is hands-off baking time) Serves: 6-8 people generously
What makes this casserole unique is the technique of salting and draining the zucchini first – this prevents that watery mess that ruins so many zucchini dishes. Here’s the secret: we’re going to draw out excess moisture, then create layers of flavor that’ll have everyone asking for your recipe!
Ingredients
Serves 6-8 people
For the Zucchini Base:
- 4 large zucchini (about 3 pounds), shredded
- 2 teaspoons salt (for draining)
- 3 large eggs, beaten
- 1 cup ricotta cheese
- 1/2 cup sour cream
- 1 medium onion, finely diced
- 3 cloves garlic, minced
For the Cheese Mixture:
- 2 cups shredded mozzarella cheese, divided
- 1/2 cup grated Parmesan cheese
- 1/4 cup fresh basil, chopped (or 2 tablespoons dried)
- 1 teaspoon dried oregano
- 1/2 teaspoon black pepper
- 1/4 teaspoon red pepper flakes (optional, but so good!)
For the Topping:
- 1/2 cup panko breadcrumbs
- 2 tablespoons butter, melted
- Extra Parmesan for sprinkling
Pro tip: Don’t skip the ricotta cheese – it adds this amazing creamy texture that makes the casserole feel really special. And if you can find fresh basil, use it! The flavor difference is incredible.
Ingredient Substitutions: You can swap the ricotta for cottage cheese if that’s what you have, and Greek yogurt works great instead of sour cream. For a lighter version, try using part-skim mozzarella, though I personally think the full-fat cheese is worth it for special occasions!
Cooking Method
Step 1: Prep Your Zucchini (15 minutes)
Start by shredding all your zucchini using the large holes of a box grater. This is where I like to get the kids involved – they love helping with the grating! Place all that beautiful green goodness in a large colander and toss with the salt. Let it sit for about 15 minutes while you prep everything else.
Here’s where the magic happens: after 15 minutes, grab handfuls of the salted zucchini and squeeze out as much liquid as you possibly can. I’m talking really get in there and wring it out like you’re doing laundry! This step is absolutely crucial – trust me on this one. All that excess water would turn your gorgeous casserole into a soggy mess.
Step 2: Create Your Flavor Base (10 minutes)
Preheat your oven to 375°F and grease a 9×13 inch baking dish. In a large mixing bowl, whisk together the beaten eggs, ricotta, and sour cream until it’s nice and smooth. This creamy mixture is what’s going to bind everything together beautifully.
Add your diced onion, minced garlic, 1 1/2 cups of the mozzarella (save that extra half cup for the top!), Parmesan, basil, oregano, black pepper, and red pepper flakes if you’re using them. Mix it all up until it looks like the most delicious, creamy vegetable mixture you’ve ever seen.
Step 3: Combine and Season (5 minutes)
Now fold in your perfectly drained zucchini. Don’t worry if it seems like a lot of zucchini – it’s going to cook down and become absolutely perfect. Taste the mixture and add a pinch more salt if needed, but remember, we already salted the zucchini, so go easy!
Pro tip: This is where I always add a little extra garlic powder because, let’s be honest, there’s no such thing as too much garlic in my kitchen!
Step 4: Assemble Your Masterpiece (5 minutes)
Spread the zucchini mixture evenly in your prepared baking dish. Sprinkle the remaining mozzarella cheese over the top – this is going to create that gorgeous golden, bubbly surface we’re all here for!
In a small bowl, mix the panko breadcrumbs with the melted butter, then sprinkle this over the cheese layer. Finish with a generous dusting of extra Parmesan cheese. You’ve got this – it’s going to look absolutely beautiful!
Step 5: Bake to Golden Perfection (25-30 minutes)
Slide that beauty into your preheated oven and bake for 25-30 minutes, until the top is golden brown and bubbly, and a knife inserted in the center comes out mostly clean. The edges should be set and slightly pulling away from the sides of the dish.
Let it rest for about 10 minutes before serving – I know it’s torture to wait, but this helps everything set up perfectly for clean, beautiful slices.
Chef’s Tips & Variations
Storage Secrets: This casserole actually gets better overnight! Store leftovers covered in the refrigerator for up to 4 days. To reheat, just pop individual portions in the microwave for 1-2 minutes, or reheat the whole dish covered in a 350°F oven for about 20 minutes.
Make-Ahead Magic: You can assemble this entire casserole up to 24 hours ahead! Just cover it tightly and refrigerate, then add an extra 5-10 minutes to the baking time since you’re starting with a cold dish.
Flavor Variations I Love:
- Mexican Style: Add some cumin, chili powder, and pepper jack cheese, then top with crushed tortilla chips
- Mediterranean Twist: Use feta cheese instead of ricotta and add sun-dried tomatoes and fresh dill
- Protein Power: Fold in some cooked ground turkey or leftover rotisserie chicken for a complete meal
Pro Tips from My Kitchen:
- Always, always drain that zucchini properly – it’s the difference between success and soup!
- Room temperature eggs mix better, so take them out about 30 minutes before cooking
- A cast iron skillet works beautifully for this recipe if you don’t have a casserole dish
- Double the recipe and freeze one for later – future you will thank present you!
Perfect Pairings: This casserole is incredible alongside grilled chicken, a simple green salad with lemon vinaigrette, or even just some crusty garlic bread. It’s hearty enough to be vegetarian main dish too!
