Why You’ll Love This Recipe
I love this zucchini casserole because it’s the perfect balance of fresh vegetables and cheesy indulgence. I often serve it at potlucks or cozy family dinners, and it always disappears quickly. The melty cheese and golden topping make it appealing even to picky eaters, while the tender zucchini keeps it light. It’s versatile enough to be the main dish or a hearty side, and I enjoy switching it up with different cheeses or spices.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
4 medium zucchinis, sliced
1 cup shredded mozzarella cheese
1 cup shredded cheddar cheese
3 large eggs
1 sweet onion, finely chopped
1 tsp garlic powder
1 cup seasoned breadcrumbs
2 tbsp olive oil
Salt and pepper to taste
Directions
Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish with olive oil or cooking spray.
In a skillet, heat olive oil over medium heat and sauté the chopped onion until translucent, about 5 minutes.
Add sliced zucchini and garlic powder, then cook until just tender, about 3–4 minutes.
In a bowl, whisk eggs with salt and pepper.
Combine sautéed vegetables with cheeses and egg mixture in a large bowl. Mix gently.
Pour mixture into the prepared baking dish, spread evenly, and sprinkle breadcrumbs on top.
Bake for 30–35 minutes, until golden brown and bubbly.
Servings and timing
This recipe serves 8 people. It takes about 15 minutes of prep time and 35 minutes of baking time, so the total cooking time is 50 minutes.
Variations
I like to make small changes depending on the occasion:
Swap zucchini for yellow squash or use a mix of both for color.
Use different cheeses such as feta, parmesan, or gouda for new flavors.
Add cooked ground turkey, chicken, or sausage to make it a protein-packed main dish.
Mix in fresh herbs like thyme, oregano, or basil for a fragrant twist.
Storage/Reheating
I store leftovers in an airtight container in the refrigerator for up to three days. To reheat, I prefer using the oven at 350°F (175°C) for 10–15 minutes to bring back the crispy topping. The microwave works in a pinch, but the breadcrumbs won’t stay as crunchy.
FAQs
Can I use frozen zucchini for this zucchini casserole?
I can use frozen zucchini, but I make sure to thaw it first and drain excess moisture. This prevents the casserole from turning watery.
What can I serve with zucchini casserole?
I usually serve it with a fresh green salad, roasted chicken, or grilled fish. It also pairs well with crusty bread to soak up the cheesy goodness.
How can I make this recipe gluten-free?
I simply swap the seasoned breadcrumbs for a gluten-free version or use crushed gluten-free crackers. Everything else in the recipe stays the same.
Can I prepare zucchini casserole ahead of time?
Yes, I often assemble it earlier in the day, cover it, and refrigerate until baking time. This makes it perfect for dinner parties or busy evenings.
How do I keep zucchini from getting soggy in the casserole?
I sauté the zucchini just until slightly tender and avoid overcooking before baking. This way, it holds its texture in the oven.
