The combination of zucchini, onion, parmesan, and dill baked together with eggs and baking mix creates a savory casserole with a moist texture and golden top.

How to Make This Recipe

The process begins by preparing the vegetables. Zucchini is diced into small pieces so that it cooks evenly and blends well with the other ingredients. Onion is chopped finely, adding both sweetness and depth of flavor. The dry ingredients—baking mix, parmesan cheese, dill, salt, and black pepper—are combined in a bowl. The eggs and oil are whisked separately before everything is brought together into a smooth batter. Once the vegetables are folded in, the mixture is transferred to a casserole dish and baked until golden and firm.

This recipe works well for busy days because the prep is quick, and the oven does the rest of the work. Within half an hour, you have a fragrant casserole ready to serve.

Step-by-Step Instructions for Making

  1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). This ensures the casserole bakes evenly from the start.

  2. Prepare the Baking Dish: Lightly grease a medium-sized casserole dish with oil or nonstick spray to prevent sticking.

  3. Mix Dry Ingredients: In a large bowl, combine the baking mix, shredded parmesan cheese, dried dill, salt, and black pepper. Stir well so that the seasoning is evenly distributed.

  4. Beat the Wet Ingredients: In a separate bowl, whisk together the eggs and canola oil until smooth. This mixture provides moisture and structure for the casserole.

  5. Combine Mixtures: Pour the egg and oil mixture into the bowl with the dry ingredients. Stir gently until combined into a thick batter.

  6. Fold in Vegetables: Add the diced zucchini and chopped onion to the batter. Mix until the vegetables are evenly coated.

  7. Transfer to Baking Dish: Pour the mixture into the prepared casserole dish, spreading it out evenly with a spatula.

  8. Bake the Casserole: Place the dish in the preheated oven and bake for 25 to 30 minutes, or until the top is golden and the center is set. You can test doneness by inserting a toothpick into the center; it should come out clean.

  9. Cool Slightly Before Serving: Allow the casserole to rest for 5 minutes before slicing. This helps it hold together when serving.

Quick and Easy

This casserole stands out for its simplicity. The prep takes only about 10 minutes, making it one of those recipes you can throw together without stress. Since the zucchini does not require pre-cooking, you save time while still achieving a tender result. It is ideal for weeknights when you want something homemade but don’t have hours to spare.

Customizable

One of the best features of this recipe is how adaptable it is. You can switch the parmesan cheese for cheddar if you prefer a sharper flavor. Fresh herbs like parsley or chives can be added alongside the dill for extra freshness. If you want more protein, mix in cooked chicken or turkey bacon before baking. You can also experiment with spices like garlic powder or paprika for a slightly different flavor profile.

Crowd-Pleasing

This zucchini dill casserole is always a hit at family gatherings and potlucks. Its soft texture and gentle seasoning make it appealing to almost everyone. Since it can be enjoyed warm or at room temperature, it travels well and stays tasty even after sitting out for a while. Guests will appreciate the light, herby flavor and the comforting feel of baked zucchini.

With its quick preparation, customizable options, and universal appeal, this casserole is one of those recipes that you will find yourself making again and again. It is wholesome, practical, and guaranteed to be enjoyed by both small families and larger groups.
