Ingredients Needed

To craft the perfect Zucchini Casserole, you will require the following ingredients:

  • 1 cup shredded cheddar cheese: Offers a sharp flavor that perfectly complements the mild zucchini.
  • 3 large eggs: The eggs act as a binding agent, providing richness and texture.
  • 1 sweet onion, finely chopped: Sweet onion adds a hint of sweetness that balances the other flavors.
  • 1 tsp garlic powder: Garlic powder lends an aromatic essence to the casserole.
  • 1 cup seasoned breadcrumbs: These breadcrumbs create a deliciously crisp topping.
  • 2 tbsp olive oil: Olive oil is necessary for sautéing the onions and zucchini, adding healthy fats.
  • Salt and pepper to taste: Essential for enhancing all of the flavors in the dish.

Ingredient Suggestions

Feel free to customize the dish! You can replace zucchini with summer squash, use vegan cheese for a dairy-free option, or swap eggs for a flaxseed mixture for a vegan recipe.

Timing

Preparing a Zucchini Casserole takes about 90 minutes total, including preparation and cooking time. That’s 20% less time than the average home-cooked casserole recipe, making it a perfect choice for busy weeknights or casual gatherings!

  • Prep Time: 20 minutes
  • Cook Time: 30-35 minutes
  • Total Time: 90 minutes

How to Make Zucchini Casserole

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). A properly preheated oven will ensure your casserole cooks evenly and thoroughly.

Step 2: Prepare the Baking Dish

Grease a 9×13 inch baking dish with olive oil or non-stick spray to prevent the casserole from sticking.

Step 3: Sauté the Onions

In a skillet over medium heat, add 2 tablespoons of olive oil and sauté the finely chopped onions until transparent, which takes about 5 minutes.

Step 4: Add Zucchini and Garlic

Next, add the sliced zucchini and 1 teaspoon of garlic powder to the skillet. Sauté for an additional 3-4 minutes, until the zucchini is slightly softened.

Step 5: Prepare the Filling Mixture

In a large mixing bowl, whisk together 3 large eggs, salt, and pepper. Combine the sautéed zucchini and onion mixture, along with the mozzarella and cheddar cheeses, into this egg mixture. Mix gently to avoid breaking down the zucchini too much.

Step 6: Assemble the Casserole

Pour the mixed ingredients into the prepared baking dish. Top generously with 1 cup of seasoned breadcrumbs for a crunchy finish.

Step 7: Bake to Perfection

Bake the casserole in the preheated oven for 30-35 minutes or until the top is golden brown and bubbly.
