Air Fryer Zucchini Casserole Recipe Tips

  • Preheat your air fryer: To ensure an even cook, preheat your air fryer to 320°F before placing the casserole in.
  • Cut zucchini evenly: Chop the zucchini into small, even pieces so they cook uniformly.
  • Don’t overfill the pan: Make sure to leave some space around the casserole for air circulation for a crispier finish.
  • Use a non-stick pan: For easy removal, use a non-stick, air fryer-safe pan.
  • Check for doneness: After 15 minutes, check if the casserole is golden and cooked through. If not, add a few extra minutes to ensure it’s fully cooked.

Air Fryer Zucchini Casserole Recipe Faqs

Can I use frozen zucchini for this recipe? It’s best to use fresh zucchini for this casserole to achieve the right texture. Frozen zucchini tends to release more water, which may affect the casserole’s consistency.

Can I substitute the eggs in this recipe? Yes! You can replace the eggs with a flaxseed meal or chia seed egg substitute, which works well for binding the ingredients together.

Can I make this casserole ahead of time? Absolutely! You can prepare the casserole and store it in the fridge before cooking. Just cover it and refrigerate for up to 24 hours, then cook when ready.

Can I add other vegetables to this casserole? Yes! Feel free to add vegetables like bell peppers, mushrooms, or spinach for extra flavor and texture. Just be sure to chop them finely to avoid altering the casserole’s balance.

How do I store leftovers? Leftovers can be stored in an airtight container in the fridge for up to 3-4 days. To reheat, simply pop it back into the air fryer for a few minutes until heated through.

Can I make this casserole without cheese? Yes! You can omit the cheese or use a dairy-free alternative to make it suitable for various dietary preferences.

How can I make this casserole spicier? To add some heat, sprinkle in some red pepper flakes, add chopped jalapeños, or incorporate a dash of hot sauce into the mix.
