Step‑by‑Step Instructions for Zucchini Squash Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that it reaches the perfect baking temperature as you prepare your Zucchini Squash Casserole. Preheating is a vital step that will contribute to that beautifully golden, bubbling top as the casserole cooks.
Step 2: Prepare the Zucchini
Next, slice your firm zucchini into thin rounds and lay them out on a clean kitchen towel or paper towels. Generously sprinkle some salt over the slices and let them rest for about 15 minutes. This process draws out excess moisture, ensuring your casserole turns out perfectly textured rather than soggy.
Step 3: Sauté Aromatics
While your zucchini rests, heat a skillet over medium heat and add a drizzle of olive oil. Sauté chopped onions until they turn soft and translucent, about 5 minutes, before adding minced garlic. Cook for an additional minute until fragrant, allowing those aromatics to fill your kitchen while enhancing the flavors in your Zucchini Squash Casserole.
Step 4: Pat Dry and Layer Ingredients
After the zucchini has rested, pat the slices dry with a clean towel to remove any excess moisture. In a baking dish, start layering half of the zucchini slices at the bottom. Follow this with sautéed onions and garlic, a sprinkle of herbs, and a generous layer of mozzarella cheese, creating a melty base for your casserole.
Step 5: Continue Layering
Repeat the layering process with the remaining zucchini slices, topping off with tomato sauce, more herbs, and a final layer of mozzarella and parmesan cheese. This creates a hearty and comforting stack in your Zucchini Squash Casserole, which will be bursting with flavor once baked.
Step 6: Bake the Casserole
Place your baking dish in the preheated oven, allowing the casserole to bake for about 45 minutes. Keep an eye on it as it cooks; you’ll know it’s ready when the cheese is bubbly and golden brown on top, while the edges are slightly crisped.
Step 7: Cool and Serve
Once baked to perfection, carefully remove the casserole from the oven and let it cool for about 10 minutes. This resting time helps the layers set, making it easier to serve. Now your delicious Zucchini Squash Casserole is ready to bring comfort to your table!

Zucchini Squash Casserole Recipe FAQs
How do I choose the right zucchini for this casserole?
Absolutely! When selecting zucchini, look for firm, shiny skin without any soft spots or dark blemishes. Fresh zucchini should feel heavy for its size and the color should be a vibrant green. Avoid any that are overly large, as they might contain large seeds and less flavor.
What is the best way to store leftovers of the zucchini squash casserole?
Very good question! Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, you can either pop it in the microwave or reheat it in the oven at 350°F (175°C) for about 20-25 minutes, making sure to cover it with foil to keep it moist.

How do I freeze zucchini squash casserole properly?
Great question! To freeze the casserole, let it cool completely after baking. Then, wrap the dish tightly with aluminum foil or transfer the casserole to a freezer-safe container. It can be frozen for up to 2 months. When ready to enjoy, thaw it overnight in the fridge and reheat as needed at 350°F (175°C) for about 20-25 minutes.
What if my casserole seems too watery after baking?
The more the merrier! If you find your zucchini squash casserole is watery, it could be due to excess moisture from the zucchini.
