The foundation of this dish is love and adaptability.
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish to prevent sticking.
- In a large skillet, heat olive oil or butter over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes. Stir in the garlic and cook for another minute until fragrant.
- While the onions cook, thinly slice the zucchinis and set them aside. If you prefer, you can lightly salt the zucchini slices and let them sit for 10 minutes to draw out excess moisture, then pat dry. This helps prevent a watery casserole—a tip I learned from Mama Lou herself!
- In a large mixing bowl, whisk together the eggs, sour cream, mayonnaise, thyme, salt, and pepper until smooth.
- Add the sautéed onion and garlic mixture to the bowl. Then fold in the shredded cheddar, mozzarella, and Parmesan cheeses, reserving a small handful of cheddar for topping.
- Gently fold in the sliced zucchini, making sure each piece is coated with the cheesy mixture.
- Transfer the mixture to the prepared baking dish, spreading it evenly. Sprinkle the reserved cheddar cheese and breadcrumbs evenly over the top for a golden crust.
- Bake uncovered for 35-40 minutes, or until the casserole is bubbly and the top is a beautiful golden brown. A toothpick inserted into the center should come out clean.
- Remove from the oven and let it rest for 10 minutes before serving. This pause allows the casserole to set and makes for easier slicing.
One of my favorite moments is pulling this casserole out of the oven and watching Ouma’s eyes light up. It’s always the same look—pure joy and anticipation that makes all the prep worth it. Mama Lou would remind us to savor not just the food but the time spent together around the table.

Tips for Making the Best Cheesy Zucchini Casserole
Over the years, I’ve picked up some little tricks that take this casserole from good to unforgettable:
- Don’t skip salting the zucchini: This step helps remove excess moisture and prevents the casserole from becoming soggy. After salting, give the slices a gentle squeeze with a clean towel.
- Choose good-quality cheese: Sharp cheddar and a creamy mozzarella bring the perfect balance of flavor and meltiness. Sometimes, I add a touch of smoked gouda for a subtle depth, inspired by Mama Lou’s adventurous palate.
- Use fresh herbs when possible: Thyme is traditional, but rosemary or basil can add a lovely twist. Ouma and I loved experimenting with the herbs from our garden, which made each casserole a little different.
- Let it rest before serving: I can’t stress this enough. Letting the casserole cool for 10 minutes makes it easier to cut and enhances the texture.
- Breadcrumb topping is optional but recommended: It adds a delightful crunch that contrasts the creamy interior. For a gluten-free option, crushed nuts or gluten-free panko work beautifully.
Serving Suggestions and Pairings
This Cheesy Zucchini Casserole is a star on its own, but I love pairing it with dishes that balance its richness. When I think back to family dinners with Mama Lou, this casserole often shared the table with her famous roasted chicken or a crisp garden salad tossed with lemon vinaigrette.
For a lighter meal, serve it alongside a fresh tomato and basil salad, drizzled with balsamic glaze. On colder days, it pairs beautifully with a warm bowl of homemade vegetable soup or a simple garlic bread to soak up every cheesy bit.
Ouma’s favorite way to enjoy it is with a dollop of tangy Greek yogurt on top, which cuts through the richness perfectly. Whatever you choose, this casserole lends itself well to both casual weeknight dinners and cozy weekend feasts.
Storage and Reheating Tips
One of the things I appreciate most about this Cheesy Zucchini Casserole is how well it reheats—perfect for leftovers or meal prep. After a family meal, I always save a portion, knowing it’ll taste just as comforting the next day.
- Store in an airtight container in the refrigerator for up to 3 days.
- To reheat, cover with foil and warm in a 350°F (175°C) oven for 15-20 minutes until heated through.
- For a quick microwave option, heat individual servings on medium power for 1-2 minutes, stirring halfway if possible.
- If you want to freeze it, bake the casserole fully, then cool completely before wrapping tightly. Freeze for up to 2 months. Thaw overnight in the fridge and reheat as described above.
When I reheat this casserole, it always brings back that same cozy feeling I had growing up—like a little piece of Mama Lou’s kitchen is right there with me.
