Pro Tips

Here are some pro tips for making Air Fryer Zucchini Casserole:

  • Evenly slice the zucchini: Use a mandoline slicer or a sharp knife to ensure the slices are evenly cut. This will help them cook more uniformly in the air fryer.

  • Precook the zucchini: To prevent the casserole from becoming too watery, precook the zucchini slices in the air fryer for a few minutes before assembling the casserole. This helps remove excess moisture and ensures a creamy texture.

  • Layer the ingredients: Assemble the casserole in layers, alternating between zucchini slices, cheese, and other ingredients like tomatoes or onions. This creates a delicious and well-balanced flavor throughout the casserole.

  • Season generously: Season each casserole layer generously with salt, pepper, and any other herbs or spices you choose. This enhances the dish’s flavor and ensures that each bite is delicious.

  • Cover with foil: To prevent the cheese from burning during cooking, cover the casserole dish before placing it in the air fryer. This helps create a steamy environment that melts the cheese evenly.

  • Check for doneness: Keep an eye on the casserole as it cooks in the air fryer, and use a fork to test the zucchini for tenderness. Cook until the zucchini is tender and the cheese is melted and bubbly.

  • Let it rest: Allow the casserole to rest for a few minutes after removing it from the air fryer. This allows the flavors to meld together, making it easier to slice and serve.

  • Customize toppings: Before serving, add any desired toppings, such as chopped fresh herbs, breadcrumbs, or a drizzle of balsamic glaze, to enhance the dish’s flavor and texture.

By following these pro tips, you can make a delicious and flavorful Air Fryer Zucchini Casserole that’s sure to impress!




Can I use other vegetables in the casserole besides zucchini? You can customize the casserole by adding other vegetables, such as yellow squash, eggplant, bell peppers, or tomatoes. Just keep in mind that different vegetables may require different cooking times.

Do I need to peel the zucchini before slicing? Peeling the zucchini before slicing is not necessary, as the skin adds color and texture to the casserole. However, you can peel it if you prefer a smoother texture.

How do I prevent the casserole from becoming too watery? To prevent the casserole from becoming too watery, sprinkle salt over the sliced zucchini and let it sit for 10-15 minutes. Then, pat the zucchini dry with paper towels before assembling the casserole.

Can I use frozen zucchini in the casserole? While fresh zucchini is preferred for best results, you can use frozen zucchini if you have it on hand. Just make sure to thaw and drain the zucchini well before using it in the casserole to remove excess moisture.

How do I store leftover casserole? Allow the casserole to cool completely, transfer it to an airtight container, and refrigerate for 3-4 days. Then, reheat individual servings in the microwave or oven until heated through.

Can I freeze the casserole for later? Yes, you can. Allow it to cool completely, then transfer it to a freezer-safe container or resealable plastic bag. Freeze for up to 2-3 months. To reheat, thaw overnight in the refrigerator and then reheat in the oven or microwave until heated.

Can I make the casserole ahead of time? Yes, you can assemble the casserole and refrigerate it, covered, for up to 24 hours before baking. This is convenient for meal prep or when hosting a gathering.

Can I add meat or protein to the casserole? You can add cooked meat such as ground beef, sausage, or shredded chicken to the casserole for added protein. Just ensure the meat is fully cooked before adding it to the dish.
