Ingredients
Main Ingredients:
-
3 cups zucchini, thinly sliced or grated
-
1 large onion, thinly sliced
-
2 tablespoons olive oil or butter
-
3 large eggs
-
1 cup (100 g) shredded cheese (cheddar, mozzarella, or a blend)
-
½ cup (60 g) all-purpose flour or biscuit mix
-
½ teaspoon baking powder (if using flour)
-
½ teaspoon salt
-
¼ teaspoon black pepper
Optional Additions:
-
½ teaspoon garlic powder or fresh minced garlic
-
1 tablespoon fresh parsley or dill
-
¼ teaspoon paprika or chili flakes for a slight kick
-
¼ cup grated Parmesan cheese for extra flavor
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9-inch pie dish or baking pan lightly with oil or butter.
Step 2: Prepare the Vegetables
Wash and slice or grate the zucchini. If using grated zucchini, squeeze out excess moisture using a clean kitchen towel.
Thinly slice the onion for even cooking.
Step 3: Sauté the Onion and Zucchini
In a large skillet, heat olive oil or butter over medium heat.
Add the onions and cook for 5–7 minutes until soft and slightly caramelized.
Add the zucchini and cook for another 5 minutes, stirring occasionally, until tender. Remove from heat and let cool slightly.
Step 4: Prepare the Batter
In a large mixing bowl, whisk together the eggs, flour (or biscuit mix), baking powder (if using), salt, and pepper.
Stir in the shredded cheese and any optional seasonings or herbs.
Step 5: Combine Everything
Add the sautéed zucchini and onion mixture to the batter. Mix until everything is evenly combined.
Step 6: Bake the Pie
Pour the mixture into the prepared pie dish and spread evenly.
Bake for 30–40 minutes, or until the top is golden brown and the center is set. A knife inserted in the center should come out clean.
Step 7: Cool and Serve
Let the pie cool for 10–15 minutes before slicing. This helps it set and makes serving easier.
Serve warm or at room temperature.
Tips for Perfect Zucchini Onion Pie
-
Remove excess moisture: Zucchini contains a lot of water—squeezing it out prevents a soggy pie.
-
Cook vegetables first: Sautéing enhances flavor and ensures proper texture.
-
Use good cheese: Sharp cheddar or Parmesan adds depth of flavor.
-
Don’t overbake: Keeps the pie soft and tender.
-
Let it rest: Cooling slightly helps the pie firm up.
