How to Make Simple Zucchini Dill Casserole
Step 1: Combine the Dry Ingredients
Grab a large mixing bowl and get ready to build a flavor-packed foundation. Whisk together the baking mix, shredded parmesan cheese, dried dill, salt, and black pepper. This step is crucial because it makes sure that every bite is seasoned perfectly, and the dill gets beautifully dispersed for herby goodness from edge to edge.
Step 2: Add the Wet Ingredients
Next, make a little well in the center of your dry mixture and pour in the lightly beaten eggs and canola oil. Stir it all together until you’ve got a uniform, smooth, and slightly thick batter. This ensures a cohesive texture in your finished Simple Zucchini Dill Casserole — no dry pockets or oily surprises!
Step 3: Fold in the Vegetables
Now, it’s time for the stars of the show — fold in your diced zucchini and chopped onion gently. Mix just until everything is evenly combined. This step brings the color and crunch, and makes sure every slice is dotted with green zucchini and sweet onion in every bite.
Step 4: Prep the Baking Dish
Lightly grease a 1-1/2-quart baking dish with oil or nonstick spray to guarantee easy serving later on. Pour in the batter, smoothing it out evenly from corner to corner with a spatula. Even distribution means even baking, so don’t skip this little touch.
Step 5: Bake Until Golden and Set
Pop your casserole into a preheated 375°F (190°C) oven and let it bake, uncovered, for 25 to 30 minutes. You’re looking for a gorgeous golden brown top, and when a toothpick comes out clean, you’ll know it’s ready. Allow it to cool for a few minutes to set before you slice — anticipation is half the fun!
How to Serve Simple Zucchini Dill Casserole

Garnishes
A little garnish goes a long way! A sprinkle of extra dill on top not only enhances the herbaceous aroma but also hints at the flavors inside. For extra color and freshness, try scattering finely chopped chives or a handful of microgreens just before serving your Simple Zucchini Dill Casserole.

This casserole shines alongside crisp green salads, a simple bowl of tomato soup, or lightly roasted potatoes. It plays well with just about anything — from grilled chicken to a platter of fresh fruit — making it a versatile addition to any meal.
Creative Ways to Present
Portion the casserole into individual ramekins for a brunch-worthy touch, or cut it into bite-sized squares for a cheerful potluck platter. You can even top each piece with a dollop of sour cream and a sprig of dill to dress it up for special occasions!
Make Ahead and Storage
Storing Leftovers

Reheating
To reheat, pop individual slices in the microwave for 1-2 minutes or warm the whole casserole in a 325°F (160°C) oven until heated through. A quick splash of water or a cover of foil helps keep everything moist and tender.
