- 1 tablespoon dried dill: Brings a fresh, herbal brightness that pairs perfectly with zucchini.
- 1 teaspoon salt: Enhances all the flavors without overpowering.
- 1/8 teaspoon black pepper: Offers a subtle hint of warmth and spice.
- 4 large eggs (slightly beaten): Binds the ingredients together with richness and moisture.

How to Make Simple Zucchini Dill Casserole Recipe
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that the casserole bakes evenly and develops that beautiful golden crust while the inside remains tender and moist.
Step 2: Combine Dry Ingredients
In a large mixing bowl, whisk together the baking mix, shredded parmesan cheese, dried dill, salt, and black pepper. This dry mixture forms the flavorful foundation for your casserole and ensures those herbs and cheese are evenly distributed.
Step 3: Mix Wet Ingredients
In a separate bowl, beat the eggs slightly and combine them with the canola oil until smooth. This liquid mixture will add moisture and richness to the casserole, helping bind everything perfectly.
Step 4: Blend Wet and Dry Mixtures
Pour the egg and oil mixture into the bowl with your dry ingredients and stir gently until everything just comes together. Be careful not to overmix here; you want a cohesive batter without being tough.
Step 5: Fold in Zucchini and Onion
Now fold in the diced zucchini and chopped onion, distributing them evenly throughout the batter. These veggies bring wonderful freshness and slight crunch to the casserole, making every bite satisfying.
Step 6: Bake Until Golden
Grease a casserole dish and pour in your batter, smoothing out the top. Bake in the preheated oven for about 25 minutes or until the top looks nicely golden brown and the casserole feels set when gently pressed. The aroma will be impossible to ignore!
How to Serve Simple Zucchini Dill Casserole Recipe

Garnishes
A sprinkle of fresh dill or chopped green onions on top right before serving adds a vibrant pop of color and reinforces that lovely herbaceous note that makes this casserole sing. A dollop of sour cream or Greek yogurt can also add a creamy tang that pairs beautifully.
Side Dishes
This casserole shines as a main or a side, pairing wonderfully with grilled chicken, seared fish, or a fresh leafy salad. For a cozy meal, consider serving with warm crusty bread or a simple tomato salad to complement those garden-fresh flavors.
Creative Ways to Present
For entertaining, try serving the casserole in individual ramekins to make it feel extra special. You can also layer in other veggies like roasted red peppers or mushrooms for personalized twists. Drizzling a bit of lemon-infused olive oil over the top before serving adds a zesty brightness that guests will adore.
Make Ahead and Storage
Storing Leftovers
This zucchini dill casserole keeps very well in the fridge for up to 3 days. Store it in an airtight container to maintain freshness and avoid absorbing other flavors from your fridge.
Freezing
If you want to enjoy this dish later, it freezes beautifully. Wrap it tightly or use freezer-safe containers. When ready to eat, thaw overnight in the fridge before reheating to preserve the texture and flavor.
Reheating
Reheat leftovers in the oven at 350°F until warmed through for best results. Microwaving works in a pinch, but the oven will help maintain that satisfying crispy top that makes this casserole feel freshly baked.
FAQs
Can I use fresh dill instead of dried in this recipe?
Absolutely! If using fresh dill, use about three times the amount called for dried, so around 3 tablespoons, to get the same flavor impact.
Is there a way to make this zucchini dill casserole gluten-free?
Yes, simply substitute the baking mix with a gluten-free baking mix of your choice. Just make sure it has similar properties to keep the texture right.
Can I add other vegetables to this casserole?
For sure! Bell peppers, mushrooms, or spinach would complement the zucchini and dill well. Just make sure to adjust the moisture levels if adding watery veggies.
What is the best way to dice zucchini for this recipe?
Try to keep your zucchini pieces roughly the same size, about half an inch cubes. This ensures even cooking and a pleasing texture throughout the casserole.
Can I prepare this casserole a day in advance?
Yes, you can assemble the casserole the day before and keep it covered in the fridge. Bake it fresh when ready to serve for the best flavor and texture.
