- Black pepper: Brings a subtle warmth and depth to the dish.
- Large eggs: Provide structure and moisture, helping the casserole hold its shape.

How to Make Simple Zucchini Dill Casserole Recipe
Step 1: Preheat and Prepare
Start by heating your oven to 350°F (175°C). This perfect temperature ensures the casserole cooks evenly and develops that irresistible golden brown top. Also, be sure to grease your casserole dish so the finished dish slides out easily and the edges crisp up nicely.
Step 2: Mix the Dry Ingredients
In a large bowl, combine the baking mix, shredded parmesan cheese, dried dill, salt, and black pepper. Mixing these dry ingredients first helps distribute the flavors evenly and ensures that each bite bursts with the herbaceous dill and savory parmesan.
Step 3: Whisk the Wet Ingredients
In a separate bowl, whisk the eggs until slightly frothy and then slowly incorporate the canola oil. This mixture adds moisture and richness to the casserole while helping it set perfectly as it bakes.
Step 4: Combine Wet and Dry
Pour the wet egg and oil mixture into the dry ingredients, stirring gently but thoroughly. The batter should become smooth and just a little thick, ready to embrace the fresh vegetables.
Step 5: Fold in Vegetables
Gently fold the diced zucchini and chopped onion into the batter. The folding technique keeps the zucchini from becoming mushy, allowing every bite to have beautiful chunks of tender veggies blended with the soft batter.
Step 6: Bake to Perfection
Pour the mixture into your prepared casserole dish and spread it evenly. Bake it for about 25 minutes until the top is golden and crisp, signaling it’s time to dig in and enjoy the wonderful aromas filling your kitchen.
How to Serve Simple Zucchini Dill Casserole Recipe

Garnishes
A sprinkle of fresh dill or a light dusting of extra parmesan on top just before serving adds a burst of color and flavor. This final touch also enhances the fresh, garden-inspired nature of the casserole.
Side Dishes
This zucchini dill casserole pairs wonderfully with a simple green salad dressed in lemon vinaigrette or a plate of roasted cherry tomatoes. For a heartier meal, serve it alongside grilled chicken or baked fish to balance the meal with protein.
Creative Ways to Present
For dinner parties or special occasions, try scooping the casserole into individual ramekins and presenting them with tiny sprigs of fresh dill or a dollop of sour cream on top. This makes it feel extra special and personal, turning a humble casserole into a star dish.
Make Ahead and Storage
Storing Leftovers
Simply cover the casserole tightly and store in the refrigerator for up to three days. The flavors will develop even more, and you can quickly reheat portions whenever you need a quick, wholesome bite.
Freezing
You can freeze leftover casserole in airtight containers for up to two months. When you’re ready to enjoy it again, thaw overnight in the fridge and then reheat for the best texture and flavor.
Reheating
For the tastiest results, reheat your casserole in the oven at 350°F for 10-15 minutes until warmed through. This method helps keep the topping crisp instead of soggy like the microwave sometimes does.
FAQs
Can I substitute fresh dill for dried dill in the Simple Zucchini Dill Casserole Recipe?
Yes! Fresh dill can be used instead of dried. Use about three times the amount since fresh herbs are less concentrated. Add it towards the end of mixing to maintain its bright flavor.
Is this casserole gluten-free?
It depends on the baking mix you choose. If you select a gluten-free baking mix, then the casserole can be gluten-free. Always check the package to be sure!
Can I use a different cheese instead of parmesan?
Parmesan offers a distinct nutty flavor and good browning, but you can try cheddar, gruyere, or even a mix of cheeses to switch things up. Keep in mind that flavor and texture might change slightly.
How do I make the casserole less oily?
Try reducing the canola oil slightly or substitute half of it with Greek yogurt for a lighter, tangy flavor while still maintaining moisture. Just note that texture may differ a bit.
Can I add other vegetables to the Simple Zucchini Dill Casserole Recipe?
Absolutely! Feel free to fold in diced bell peppers, shredded carrots, or spinach for extra color and nutrition. Just make sure to squeeze out excess moisture from watery veggies to keep the casserole from becoming soggy.

There’s something truly wonderful about how this Simple Zucchini Dill Casserole Recipe combines easy everyday ingredients into a dish that feels special but is incredibly approachable.
