Description

This easy Air Fryer Zucchini Casserole bakes fresh zucchini, onion, and cheese into a golden, savory casserole in just 15 minutes — a quick, family-favorite side dish for summer.

Ingredients 

  • 3 cups zucchini, chopped (about 3 small zucchini)
  • 1/2 cup onion, chopped
  • 4 large eggs, beaten
  • 1 cup Bisquick, or gluten-free baking mix
  • 1/2 cup vegetable oil
  • 1/2 cup shredded cheese
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon dried parsley
  • 1/2 teaspoon dried oregano

Instructions

  • Chop the zucchini into small pieces until you have 3 cups, then chop the onion.
  • Add the zucchini and onion to a large bowl with the salt, pepper, parsley, and oregano, and mix well.
  • Stir in the eggs, vegetable oil, Bisquick, and shredded cheese until fully combined.
  • Pour the mixture into a greased, oven-safe baking dish that fits inside your air fryer.
  • Set the air fryer to 320 degrees F and cook for 15 minutes.
  • Check the casserole — the top should be golden and the center set. Add a few more minutes if needed.
  • Let cool slightly, then slice and serve.

Equipment

  • Air fryer (basket or oven style)
  • Oven-safe baking dish that fits your air fryer
  • Large Mixing Bowl

Notes

  • Air fryers vary: start checking at 15 minutes and judge by a golden top and set center.
  • Prevent a watery casserole: pat the chopped zucchini dry with paper towels before mixing.
  • Gluten-free: swap the Bisquick for a gluten-free baking mix, cup for cup.
  • Storage: refrigerate covered up to 4 days; reheat in the air fryer at 350°F for 4–5 minutes.
