Garden Zucchini Casserole

Ingredients

• 3 medium zucchini, sliced or grated

• 6 large eggs

• 1 cup shredded cheddar cheese

• ½ cup grated Parmesan cheese

• ½ cup chopped onion

• 2 cloves garlic, minced

• ½ cup milk

• ¼ cup all-purpose flour

• 2 tablespoons olive oil

• 2 tablespoons chopped fresh parsley

• 1 teaspoon dried Italian seasoning

• ½ teaspoon salt, or to taste

• ¼ teaspoon black pepper

• ½ teaspoon paprika (optional)

• Fresh rosemary for garnish (optional)

Instructions

Step 1: Prepare the zucchini

Preheat your oven to 375°F (190°C). Lightly grease a baking dish with olive oil. Slice or grate the zucchini, sprinkle lightly with salt, and let it sit for 10 minutes. Squeeze out excess moisture using a clean kitchen towel to prevent a watery casserole.

Step 2: Cook the aromatics

Heat olive oil in a skillet over medium heat. Add the chopped onion and cook for 3–4 minutes until softened. Add the minced garlic and cook for another 30 seconds.

Step 3: Prepare the egg mixture

In a large bowl, whisk together the eggs, milk, flour, Italian seasoning, black pepper, and paprika. Mix until smooth and well combined.

Step 4: Add the vegetables and cheese

Stir the prepared zucchini, cooked onion and garlic, parsley, cheddar cheese, and Parmesan into the egg mixture. Mix gently so everything is evenly distributed.

Step 5: Assemble the casserole

Pour the mixture into the greased baking dish. Spread it evenly and sprinkle a little extra Parmesan cheese over the top for a delicious golden crust.

Step 6: Bake

Bake for 35–45 minutes, or until the top is golden brown and the center is set. A knife inserted into the center should come out without liquid egg mixture.

Step 7: Rest and serve

Allow the casserole to rest for 5–10 minutes before slicing. Garnish with fresh rosemary or parsley and serve warm.

Tips for the Best Zucchini Casserole

• Avoid excess moisture: Squeeze the zucchini thoroughly before mixing.

• Make it extra cheesy: Add mozzarella for a softer, stretchy cheese texture.

• Add more vegetables: Chopped spinach, mushrooms, or bell peppers work beautifully.

• Make it gluten-free: Replace all-purpose flour with a suitable gluten-free flour blend.

• Store leftovers: Refrigerate in an airtight container for up to 3–4 days.

• Reheat: Warm individual portions in the oven or microwave until heated through.

Questions & Answers (Q&A)

Q1: Can I make Garden Zucchini Casserole ahead of time?

Yes! Prepare the mixture, cover, and refrigerate it for up to 24 hours before baking. For best texture, remove excess zucchini moisture first.

Q2: Do I need to peel the zucchini?

No. The skin is tender, adds color, and helps the casserole hold its texture.

Q3: Why is my zucchini casserole watery?

Zucchini contains a lot of water. Salt it briefly, then squeeze out as much liquid as possible before adding it to the mixture.

Q4: Can I make this casserole without flour?

Yes. You can omit the flour for a more egg-based casserole, although the texture may be softer. Allow it to rest before slicing.

Q5: Can I add meat?

Absolutely! Cooked, crumbled turkey sausage, diced ham, or cooked chicken can add extra protein. Make sure all meat is fully cooked before mixing it in.

Q6: Is Garden Zucchini Casserole suitable for meal prep?

Yes. Cut it into portions and refrigerate them in airtight containers. It makes a convenient breakfast, lunch, or dinner.

Q7: What can I serve with this casserole?

Serve it with a fresh garden salad, roasted tomatoes, whole-grain toast, or grilled chicken for a balanced meal.

Q8: How do I know when it is fully cooked?

The top should be golden brown, the center should be set, and the egg mixture should not look wet or runny.
