This cheesy zucchini casserole is a delightful dish that combines the fresh flavors of zucchini with the rich, creamy taste of vegan cheese. It's a perfect option for those looking for a comforting, plant-based meal that's both satisfying and nutritious. The addition of nutritional yeast and breadcrumbs gives it a deliciously crunchy topping, making it a crowd-pleaser for any dinner table.
If you're not familiar with nutritional yeast, it's a deactivated yeast that has a cheesy, nutty flavor and is often used in vegan cooking. You can find it in the health food section of most supermarkets. Vegan cheese is another ingredient you might need to look for specifically; it’s usually located in the dairy-free or vegan section. Make sure to pick up some breadcrumbs as well, which are typically found in the baking aisle.
Ingredients For Cheesy Zucchini Casserole
Zucchinis: Fresh, large zucchinis are the base of this casserole, providing a tender and mild flavor.
Vegan cheese: This dairy-free alternative melts beautifully and adds a creamy, cheesy taste.
Breadcrumbs: These add a crunchy texture to the top of the casserole.
Nutritional yeast: Adds a cheesy, nutty flavor and boosts the nutritional value.
Garlic: Freshly minced garlic enhances the overall flavor with its aromatic and pungent taste.
Olive oil: Used to coat the zucchini slices, adding richness and helping them to cook evenly.
Technique Tip for This Recipe
When preparing the zucchinis, make sure to slice them evenly to ensure they cook uniformly. A mandoline slicer can be particularly useful for achieving consistent thickness. This will help the casserole bake evenly and prevent some slices from being undercooked while others are overcooked. Additionally, allowing the zucchini slices to sit with a light sprinkle of salt for about 10 minutes before assembling the dish can help draw out excess moisture, preventing the casserole from becoming too watery.

How to Store or Freeze This Dish
Allow the casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
Transfer the cooled cheesy zucchini casserole to an airtight container. If you don't have one large enough, you can use multiple smaller containers.
For short-term storage, place the container in the refrigerator. The casserole will stay fresh for up to 3-4 days.
If you plan to keep the casserole for a longer period, consider freezing it. Wrap the container tightly with aluminum foil or plastic wrap to prevent freezer burn.
Label the container with the date so you can keep track of how long it has been stored.
When you're ready to enjoy the casserole, thaw it in the refrigerator overnight if frozen.
To reheat, preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover with foil to prevent drying out. Heat for about 20-25 minutes, or until warmed through.
For a quicker option, you can also reheat individual portions in the microwave. Place a serving on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power for 2-3 minutes, checking and stirring halfway through.
If the casserole seems a bit dry after reheating, you can add a splash of vegetable broth or a drizzle of olive oil to moisten it up.
Enjoy your reheated cheesy zucchini casserole as a main dish or a side, paired with a fresh salad or some crusty bread.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover cheesy zucchini casserole in an oven-safe dish. Cover it with aluminum foil to retain moisture. Bake for 15-20 minutes or until heated through.
For a quicker method, use the microwave. Place a portion of the casserole on a microwave-safe plate. Cover it with a microwave-safe lid or another plate to prevent splattering. Heat on medium power for 2-3 minutes, checking halfway through to ensure even heating.
If you prefer a crispy top, use a toaster oven. Preheat the toaster oven to 350°F (175°C). Place the leftover casserole in a toaster oven-safe dish. Heat for 10-15 minutes, or until the top is golden and the zucchinis are warmed through.
For stovetop reheating, use a non-stick skillet. Add a small amount of olive oil to the skillet and heat over medium-low. Place the casserole in the skillet, cover with a lid, and heat for 5-7 minutes, stirring occasionally to ensure even heating.
